  • asp.net mvc jquery + tabs +jqgrid +jqgrid loaded only for first tab

    - by niao
    Greetings, I have a problem using jqgrid and jquery tab (I am coding in asp.net mvc) I have two tabs. Each tabs should contains jqgrid with different data. I specify tabs as follows: <script type="text/javascript"> $(document).ready(function() { $("#tabs").tabs(); getContentTab (1); }); function getContentTab(index) { var url='<%= Url.Content("~/Admin/GetWorkspaces") %>/' + index; var targetDiv = "#tabs-" + index; var ajaxLoading = "<img id='ajax-loader' src='<%= Url.Content("~/Content") %>/ajax-loader.gif' align='left' height='28' width='28'>"; $(targetDiv).html("<p>" + ajaxLoading + " Loading...</p>"); $.get(url,null, function(result) { $(targetDiv).html(result); }); } </script> <div id="tabs"> <ul> <li><a href="#tabs-1" onclick="getContentTab(1);">tab1</a></li> <li><a href="#tabs-2" onclick="getContentTab(2);">tab2</a></li> </ul> <div id="tabs-1"> </div> <div id="tabs-2"> </div> </div> As seen above GetWorkspaces action gets my tabs: public ActionResult GetWorkspaces(int id) { string viewName = string.Empty; switch (id) { case 1: viewName = "MarketplaceOfferView"; break; case 2: viewName = "MyMessagesView"; break; } return PartialView(viewName); } each of view is a partial view. In these partial views I have jqgrids specified as follows: <script type="text/javascript"> jQuery("#list").ready(function() { jQuery("#list").jqGrid({ url: '/Admin/GetGridData/', datatype: 'json', mtype: 'GET', colNames: ['Klient', 'Zapytanie', 'Atrakcyjnosc', 'Cena', 'Data poczatkowa', 'Data koncowa', 'Branza', 'Lokalizacja' ], colModel: [ { name: 'CompanyName', index: 'CompanyName', width: 150, align: 'left' }, { name: 'Content', index: 'ContactName', width: 300, align: 'left' }, { name: 'Rating', index: 'Address', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'City', width: 150, align: 'left' }, { name: 'Price', index: 'PostalCode', width: 100, align: 'left' } ], pager: jQuery('#pager'), rowNum: 100, rowList: [5, 10, 20, 50], sortname: 'Operator.FullName', sortorder: "asc", viewrecords: true, imgpath: '/scripts/themes/steel/images', caption: 'Historia moich wiadomosci', height:400 }); // .navGrid(pager, { edit: true, add: false, del: false, refresh: true, search: false }); }); </script> Historia moich wiadomosci <table id="list" class="scroll" cellpadding="0" cellspacing="0" width="100%"> </table> <div id="pager" class="scroll" style="text-align: center;"> </div> For second view I have an action: /Admin/GetGridDataForTab2/ THe problem is that I see a jqgrid only when I click on first tab. When I click on second tab the grid is not displayed and /Admin/GetGridData/ is not executed. Does anybody have an idea what is wrong?

  • Edit and render RichText

    - by OregonGhost
    We have an application (a custom network management tool for building automation) that supports printing labels that you can cut out and insert into the devices' front displays. In earlier versions of the tool (not developed in my company), the application just pushed the strings into an Excel file that the field technician could then manipulate (like formatting text). We didn't do this in the new version because it was hard (impossible) to keep the Excel file in sync, and to avoid a binding to an external application (let alone different versions of Excel). We're using PDFSharp for rendering the labels. It has a System.Drawing-like interface, but can output to a System.Drawing.Graphics (screen / printer) as well as to a PDF file, which is a requirement. Later, basic formatting was introduced like Font Family, Style, Size, Color which would apply to one label (i.e. to exactly one string). Now the customer wants to be able to apply these formats to single characters in a string. I think the easiest way would be to support a subset of RichText. It's not as easy as I thought though. Currently the editor just displays a TextBox for the label you want to edit, with the font set to the label's font. I thought I'd just replace it with RichTextBox, and update the formatting buttons to use the RichTextBox formatting properties. Fairly easy. However, I need to draw the text. I know you can get the RichTextBox to draw to a HDC or System.Drawing.Graphics - but as already said, I need it to use PDFSharp. Rendering to bitmaps is not an option, since the PDF must not be huge, and it's a lot of labels. Unfortunately I couldn't get the RichTextBox to tell me the layout of the text - I'm fine with doing the actual rendering by hand, as long as I know where to draw what. This is the first question: How can I get the properly layouted metrics of the rich text out of a RichTextBox? Or is there any way to convert the rich text to a vector graphics format that can be easily drawn manually? I know about NRTFTree which can be used to parse and manipulate RichText. The documentation is bad (actually I don't know, it's Spanish), but I think I can get it to work. As far as I understood, it won't provide layouting as well. Because of this, I think I'll have to write a custom edit control (remember, it's basically just one or two line labels with basic RTF formatting, not a full-fledged edit control - more like editing a textbox in PowerPoint) and write custom text layout logic that used PDFSharp rather than System.Drawing for drawing. Is there any existing, even if partial, solution available, either for the editing or for doing the layout manually (or both)? Or is there an entirely different approach I'm just not seeing? Bonus points if exporting the label texts as RTF into a CSV file, and then importing in Excel retains the formatting. For the editing part, I need it to work in Windows Forms. Other than that it's not Windows-Forms-related, I think.

  • Mac 10.6 Universal Binary scipy: cephes/specfun "_aswfa_" symbol not found

    - by Markus
    Hi folks, I can't get scipy to function in 32 bit mode when compiled as a i386/x86_64 universal binary, and executed on my 64 bit 10.6.2 MacPro1,1. My python setup With the help of this answer, I built a 32/64 bit intel universal binary of python 2.6.4 with the intention of using the arch command to select between the architectures. (I managed to make some universal binaries of a few libraries I wanted using lipo.) That all works. I then installed scipy according to the instructions on hyperjeff's article, only with more up-to-date numpy (1.4.0) and skipping the bit about moving numpy aside briefly during the installation of scipy. Now, everything except scipy seems to be working as far as I can tell, and I can indeed select between 32 and 64 bit mode using arch -i386 python and arch -x86_64 python. The error Scipy complains in 32 bit mode: $ arch -x86_64 python -c "import scipy.interpolate; print 'success'" success $ arch -i386 python -c "import scipy.interpolate; print 'success'" Traceback (most recent call last): File "<string>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/__init__.py", line 7, in <module> from interpolate import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/interpolate.py", line 13, in <module> import scipy.special as spec File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/__init__.py", line 8, in <module> from basic import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/basic.py", line 8, in <module> from _cephes import * ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so, 2): Symbol not found: _aswfa_ Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Expected in: flat namespace in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Attempt at tracking down the problem It looks like scipy.interpolate imports something called _cephes, which looks for a symbol called _aswfa_ but can't find it in 32 bit mode. Browsing through scipy's source, I find an ASWFA subroutine in specfun.f. The only scipy product file with a similar name is specfun.so, but both that and _cephes.so appear to be universal binaries: $ cd /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/ $ file _cephes.so specfun.so _cephes.so: Mach-O universal binary with 2 architectures _cephes.so (for architecture i386): Mach-O bundle i386 _cephes.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 specfun.so: Mach-O universal binary with 2 architectures specfun.so (for architecture i386): Mach-O bundle i386 specfun.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 Ho hum. I'm stuck. Things I may try but haven't figured out how yet include compiling specfun.so myself manually, somehow. I would imagine that scipy isn't broken for all 32 bit machines, so I guess something is wrong with the way I've installed it, but I can't figure out what. I don't really expect a full answer given my fairly unique (?) setup, but if anyone has any clues that might point me in the right direction, they'd be greatly appreciated. (edit) More details to address questions: I'm using gfortran (GNU Fortran from GCC 4.2.1 Apple Inc. build 5646). Python 2.6.4 was installed more-or-less like so: cd /tmp curl -O http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tar.bz2 tar xf Python-2.6.4.tar.bz2 cd Python-2.6.4 # Now replace buggy pythonw.c file with one that supports the "arch" command: curl http://bugs.python.org/file14949/pythonw.c | sed s/2.7/2.6/ > Mac/Tools/pythonw.c ./configure --enable-framework=/Library/Frameworks --enable-universalsdk=/ --with-universal-archs=intel make -j4 sudo make frameworkinstall Scipy 0.7.1 was installed pretty much as described as here, but it boils down to a simple sudo python setup.py install. It would indeed appear that the symbol is undefined in the i386 architecture if you look at the _cephes library with nm, as suggested by David Cournapeau: $ nm -arch x86_64 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ 00000000000d4950 T _aswfa_ 000000000011e4b0 d _oblate_aswfa_data 000000000011e510 d _oblate_aswfa_nocv_data (snip) $ nm -arch i386 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ U _aswfa_ 0002e96c d _oblate_aswfa_data 0002e99c d _oblate_aswfa_nocv_data (snip) however, I can't yet explain its absence.

  • Doing CRUD on XML using id attributes in C# ASP.NET

    - by Brandon G
    I'm a LAMP guy and ended up working this small news module for an asp.net site, which I am having some difficulty with. I basically am adding and deleting elements via AJAX based on the id. Before, I had it working based on the the index of a set of elements, but would have issues deleting, since the index would change in the xml file and not on the page (since I am using ajax). Here is the rundown news.xml <?xml version="1.0" encoding="utf-8"?> <news> <article id="1"> <title>Red Shield Environmental implements the PARCSuite system</title> <story>Add stuff here</story> </article> <article id="2"> <title>Catalyst Paper selects PARCSuite for its Mill-Wide Process...</title> <story>Add stuff here</story> </article> <article id="3"> <title>Weyerhaeuser uses Capstone Technology to provide Control...</title> <story>Add stuff here</story> </article> </news> Page sending del request: <script type="text/javascript"> $(document).ready(function () { $('.del').click(function () { var obj = $(this); var id = obj.attr('rel'); $.post('add-news-item.aspx', { id: id }, function () { obj.parent().next().remove(); obj.parent().remove(); } ); }); }); </script> <a class="del" rel="1">...</a> <a class="del" rel="1">...</a> <a class="del" rel="1">...</a> My functions protected void addEntry(string title, string story) { XmlDocument news = new XmlDocument(); news.Load(Server.MapPath("../news.xml")); XmlAttributeCollection ids = news.Attributes; //Create a new node XmlElement newelement = news.CreateElement("article"); XmlElement xmlTitle = news.CreateElement("title"); XmlElement xmlStory = news.CreateElement("story"); XmlAttribute id = ids[0]; int myId = int.Parse(id.Value + 1); id.Value = ""+myId; newelement.SetAttributeNode(id); xmlTitle.InnerText = this.TitleBox.Text.Trim(); xmlStory.InnerText = this.StoryBox.Text.Trim(); newelement.AppendChild(xmlTitle); newelement.AppendChild(xmlStory); news.DocumentElement.AppendChild(newelement); news.Save(Server.MapPath("../news.xml")); } protected void deleteEntry(int selectIndex) { XmlDocument news = new XmlDocument(); news.Load(Server.MapPath("../news.xml")); XmlNode xmlnode = news.DocumentElement.ChildNodes.Item(selectIndex); xmlnode.ParentNode.RemoveChild(xmlnode); news.Save(Server.MapPath("../news.xml")); } I haven't updated deleteEntry() and you can see, I was using the array index but need to delete the article element based on the article id being passed. And when adding an entry, I need to set the id to the last elements id + 1. Yes, I know SQL would be 100 times easier, but I don't have access so... help?

  • jquery Tab - Open Link in current panel does not work

    - by Maik Koster
    Hi, I just started playing around with the Jquery ui tabs. The content of the Tabs consist mainly of static content at the beginning. Now some of the content within the panels do have Links to some kind of subcontent. So if the User clicks on a link in the panel I would like to replace the content of the current panel with the content coming from the link. So I used the script directly from the jquery ui tab documentation but I can't get it to work. It is always opening the link directly, not within the panel. The code I use for testing is quite simple: <div id="MyTabs"> <ul> <li><a href="#TestTab1">TestTab</a></li> <li><a href="#TestTab2">TestTab</a></li> </ul> <div id="TestTab1"> Lorem ipsum dolor. dumm di dumm <a href="http://mywebserver/somelink">Test</a> </div> <div id="TestTab2"> Lorem ipsum dolor. dumm di dumm 2 <a href="http://mywebserver/somelink2">Test 2</a> </div> </div> <script type="text/javascript"> $(document).ready(function() { $('#MyTabs').tabs({ load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); }); Additionally, if I have the content of the panel loaded using an AJAX call no link within the panel is working whatsoever. Any idea what I`m doing wrong? Help is really appreciated Regards Maik Edit1: OK, I got a bit further. I replaced the Javascript with the following snippet: $(function() { $("#MyTabs").tabs(); $("#MyTabs").bind('tabsshow', function(event, ui) { AddClickHandler(ui); }); }); function AddClickHandler(ui) { $('a', ui.panel).click(function() { MyAlert("AddClickHandler"); $(ui.panel).load(this.href, AddClickHandler(ui)); return false; }); } After this change all links on a panel will update the content of the current panel. So far so good. Still one problem left. I can't get it to work for subsequent links. I tried to do it with the second "AddClickHandler" for callback when the ajax call has finished. Using a different function with a simple alert showd it is actually been called when the content of the panel has been updated. But I can't bind anything to the new links in that content. The "$('a', ui.panel)..." doesn't work. What would be the correct selector for this? Any hint? Regards Maik

  • jQuery DatePicker - 'fake' click on page load

    - by Danny
    Hey! I've got a quick question about the jQuery UI DatePicker. When I load the page, defaultDate: 0 will work fine with selecting the current day's date. I would like to create a 'fake' click on the date so it will execute my JavaScript function and retrieve information from the database. I tried calling the function when the page loads but that doesn't work. $(document).ready(function(){ $("#datepicker").datepicker({ gotoCurrent: false, onSelect: function(date, inst) { ajaxFunction(date); }, dateFormat: 'dd-mm-yy', defaultDate: 0, changeMonth: true, changeYear: true }); }); //Browser Support Code function ajaxFunction(date){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ var ajaxDisplay = document.getElementById('ajaxDiv'); ajaxDisplay.innerHTML = ajaxRequest.responseText; } } var queryString = "?date=" + date; ajaxRequest.open("GET", "getDiary.php" + queryString, true); ajaxRequest.send(null); } function ajaxAdd(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } var day1 = $("#datepicker").datepicker('getDate').getDate(); var day2 = (day1 < 10) ? '0' + day1 : day1; var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1; var month2 = (month1 < 10) ? '0' + month1 : month1; var year1 = $("#datepicker").datepicker('getDate').getFullYear(); var year2 = (year1 < 1000) ? year1 + 1900 : year1; var fullDate = day2 + "-" + month2 + "-" + year2; var queryString = "?breakfast=" + diary1.breakfast.value; queryString = queryString + "&lunch=" + diary1.lunch.value; queryString = queryString + "&dinner=" + diary1.dinner.value; queryString = queryString + "&date=" + fullDate; ajaxRequest.open("GET", "addDiary.php" + queryString, true); ajaxRequest.send(null); alert("Added value to database!"); diary1.breakfast.value = ""; diary1.lunch.value = ""; diary1.dinner.value = ""; ajaxFunction(fullDate); } I have pasted my DatePicker class, and the two functions that are used (one to retrieve information from the database, and one to store). Basically I want to mirror the onSelect: function on the DatePicker, but when the page first loads. Thanks!

  • Calculate a set of concatenated sets of n sets

    - by Andras Zoltan
    Okay - I'm not even sure that the term is right - and I'm sure there is bound to be a term for this - but I'll do my best to explain. This is not quite a cross product here, and the order of the results are absolutely crucial. Given: IEnumerable<IEnumerable<string>> sets = new[] { /* a */ new[] { "a", "b", "c" }, /* b */ new[] { "1", "2", "3" }, /* c */ new[] { "x", "y", "z" } }; Where each inner enumerable represents an instruction to produce a set of concatenations as follows (the order here is important): set a* = new string[] { "abc", "ab", "a" }; set b* = new string[] { "123", "12", "1" }; set c* = new string[] { "xyz", "xy", "x" }; I want to produce set ordered concatenations as follows: set final = new string { a*[0] + b*[0] + c*[0], /* abc123xyz */ a*[0] + b*[0] + c*[1], /* abc123xy */ a*[0] + b*[0] + c*[2], /* abc123x */ a*[0] + b*[0], /* abc123 */ a*[0] + b*[1] + c*[0], /* abc12xyz */ a*[0] + b*[1] + c*[1], /* abc12xy */ a*[0] + b*[1] + c*[2], /* abc12x */ a*[0] + b*[1], /* abc12 */ a*[0] + b*[2] + c*[0], /* abc1xyz */ a*[0] + b*[2] + c*[1], /* abc1xy */ a*[0] + b*[2] + c*[2], /* abc1x */ a*[0] + b*[2], /* abc1 */ a*[0], /* abc */ a*[1] + b*[0] + c*[0], /* ab123xyz */ /* and so on for a*[1] */ /* ... */ a*[2] + b*[0] + c*[0], /* a123xyz */ /* and so on for a*[2] */ /* ... */ /* now lop off a[*] and start with b + c */ b*[0] + c*[0], /* 123xyz */ /* rest of the combinations of b + c with b on its own as well */ /* then finally */ c[0], c[1], c[2]}; So clearly, there are going to be a lot of combinations! I can see similarities with Numeric bases (since the order is important as well), and I'm sure there are permutations/combinations lurking in here too. The question is - how to write an algorithm like this that'll cope with any number of sets of strings? Linq, non-Linq; I'm not fussed. Why am I doing this? Indeed, why!? In Asp.Net MVC - I want to have partial views that can be redefined for a given combination of back-end/front-end culture and language. The most basic of these would be, for a given base view View, we could have View-en-GB, View-en, View-GB, and View, in that order of precedence (recognising of course that the language/culture codes could be the same, so some combinations might be the same - a Distinct() will solve that). But I also have other views that, in themselves, have other possible combinations before culture is even taken into account (too long to go into - but the fact is, this algo will enable a whole bunch of really cool that I want to offer my developers!). I want to produce a search list of all the acceptable view names, iterate through the whole lot until the most specific match is found (governed by the order that this algo will produce these concatenations in) then serve up the resolved Partial View. The result of the search can later be cached to avoid the expense of running the algorithm all the time. I already have a really basic version of this working that just has one enumerable of strings. But this is a whole different kettle of seafood! Any help greatly appreciated.

  • Parallax backgrounds in OpenGL ES on the iPhone

    - by Scott
    I've got basically a 2d game on the iPhone and I'm trying to set up multiple backgrounds that scroll at different speeds (known as parallax backgrounds). So my thought was to just stick the backgrounds BEHIND the foreground using different z-coordinate planes, and just make them bigger than the foreground (in size) to accommodate, so that the whole thing can be scrolled (just at a different speed). And (as far as I know) I basically implemented that. The only problem is that it seems to entirely ignore whatever z-value I give it, or rather it just zeroes all of them. I see the background (I've only tested ONE background so far, to keep it simple...so for now I just have a foreground and I want one background scrolling at a different speed), but it scrolls 1:1 with my foreground, so it obviously doesn't look right, and most of it is cut off (cause it's bigger). And I've tried various z-values for the background and various near/far clipping planes...it's always the same. I'm probably just doing one simple thing wrong, but I can't figure it out. I'm wondering if it has to do with me using only 2 coordinates in glVertexPointer for the foreground? (Of course for the background I AM passing in 3) I'll post some code: This is some initial setup: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrthof(-1.0f, 1.0f, -1.5f, 1.5f, -10.0f, 10.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glEnableClientState(GL_VERTEX_ARRAY); //glEnableClientState(GL_COLOR_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); //transparency glEnable (GL_BLEND); glBlendFunc (GL_ONE, GL_ONE_MINUS_SRC_ALPHA); A little bit about my foreground's float array....it's interleaved. For my foreground it goes vertex x, vertex y, texture x, texture y, repeat. This all works just fine. This is my FOREGROUND rendering: glVertexPointer(2, GL_FLOAT, 4*sizeof(GLfloat), texes); <br> glTexCoordPointer(2, GL_FLOAT, 4*sizeof(GLfloat), (GLvoid*)texes + 2*sizeof(GLfloat)); <br> glDrawArrays(GL_TRIANGLES, 0, indexCount / 4); BACKGROUND rendering: Same drill here except this time it goes vertex x, vertex y, vertex z, texture x, texture y, repeat. Note the z value this time. I did make sure the data in this array was correct while debugging (getting the right z values). And again, it shows up...it's just not going far back in the distance like it should. glVertexPointer(3, GL_FLOAT, 5*sizeof(GLfloat), b1Texes); glTexCoordPointer(2, GL_FLOAT, 5*sizeof(GLfloat), (GLvoid*)b1Texes + 3*sizeof(GLfloat)); glDrawArrays(GL_TRIANGLES, 0, b1IndexCount / 5); And to move my camera, I just do a simple glTranslatef(x, y, 0.0f); I'm not understanding what I'm doing wrong cause this seems like the most basic 3D function imaginable...things further away are smaller and don't move as fast when the camera moves. Not the case for me. Seems like it should be pretty basic and not even really be affected by my projection and all that (though I've even tried doing glFrustum just for fun, no success). Please help, I feel like it's just one dumb thing. I will post more code if necessary.

  • How to pre-load all deployed assemblies for an AppDomain

    - by Andras Zoltan
    Given an App Domain, there are many different locations that Fusion (the .Net assembly loader) will probe for a given assembly. Obviously, we take this functionality for granted and, since the probing appears to be embedded within the .Net runtime (Assembly._nLoad internal method seems to be the entry-point when Reflect-Loading - and I assume that implicit loading is probably covered by the same underlying algorithm), as developers we don't seem to be able to gain access to those search paths. My problem is that I have a component that does a lot of dynamic type resolution, and which needs to be able to ensure that all user-deployed assemblies for a given AppDomain are pre-loaded before it starts its work. Yes, it slows down startup - but the benefits we get from this component totally outweight this. The basic loading algorithm I've already written is as follows. It deep-scans a set of folders for any .dll (.exes are being excluded at the moment), and uses Assembly.LoadFrom to load the dll if it's AssemblyName cannot be found in the set of assemblies already loaded into the AppDomain (this is implemented inefficiently, but it can be optimized later): void PreLoad(IEnumerable<string> paths) { foreach(path p in paths) { PreLoad(p); } } void PreLoad(string p) { //all try/catch blocks are elided for brevity string[] files = null; files = Directory.GetFiles(p, "*.dll", SearchOption.AllDirectories); AssemblyName a = null; foreach (var s in files) { a = AssemblyName.GetAssemblyName(s); if (!AppDomain.CurrentDomain.GetAssemblies().Any( assembly => AssemblyName.ReferenceMatchesDefinition( assembly.GetName(), a))) Assembly.LoadFrom(s); } } LoadFrom is used because I've found that using Load() can lead to duplicate assemblies being loaded by Fusion if, when it probes for it, it doesn't find one loaded from where it expects to find it. So, with this in place, all I now have to do is to get a list in precedence order (highest to lowest) of the search paths that Fusion is going to be using when it searches for an assembly. Then I can simply iterate through them. The GAC is irrelevant for this, and I'm not interested in any environment-driven fixed paths that Fusion might use - only those paths that can be gleaned from the AppDomain which contain assemblies expressly deployed for the app. My first iteration of this simply used AppDomain.BaseDirectory. This works for services, form apps and console apps. It doesn't work for an Asp.Net website, however, since there are at least two main locations - the AppDomain.DynamicDirectory (where Asp.Net places it's dynamically generated page classes and any assemblies that the Aspx page code references), and then the site's Bin folder - which can be discovered from the AppDomain.SetupInformation.PrivateBinPath property. So I now have working code for the most basic types of apps now (Sql Server-hosted AppDomains are another story since the filesystem is virtualised) - but I came across an interesting issue a couple of days ago where this code simply doesn't work: the nUnit test runner. This uses both Shadow Copying (so my algorithm would need to be discovering and loading them from the shadow-copy drop folder, not from the bin folder) and it sets up the PrivateBinPath as being relative to the base directory. And of course there are loads of other hosting scenarios that I probably haven't considered; but which must be valid because otherwise Fusion would choke on loading the assemblies. I want to stop feeling around and introducing hack upon hack to accommodate these new scenarios as they crop up - what I want is, given an AppDomain and its setup information, the ability to produce this list of Folders that I should scan in order to pick up all the DLLs that are going to be loaded; regardless of how the AppDomain is setup. If Fusion can see them as all the same, then so should my code. Of course, I might have to alter the algorithm if .Net changes its internals - that's just a cross I'll have to bear. Equally, I'm happy to consider SQL Server and any other similar environments as edge-cases that remain unsupported for now. Any ideas!?

  • SQLAlchemy session management in long-running process

    - by codeape
    Scenario: A .NET-based application server (Wonderware IAS/System Platform) hosts automation objects that communicate with various equipment on the factory floor. CPython is hosted inside this application server (using Python for .NET). The automation objects have scripting functionality built-in (using a custom, .NET-based language). These scripts call Python functions. The Python functions are part of a system to track Work-In-Progress on the factory floor. The purpose of the system is to track the produced widgets along the process, ensure that the widgets go through the process in the correct order, and check that certain conditions are met along the process. The widget production history and widget state is stored in a relational database, this is where SQLAlchemy plays its part. For example, when a widget passes a scanner, the automation software triggers the following script (written in the application server's custom scripting language): ' wiget_id and scanner_id provided by automation object ' ExecFunction() takes care of calling a CPython function retval = ExecFunction("WidgetScanned", widget_id, scanner_id); ' if the python function raises an Exception, ErrorOccured will be true ' in this case, any errors should cause the production line to stop. if (retval.ErrorOccured) then ProductionLine.Running = False; InformationBoard.DisplayText = "ERROR: " + retval.Exception.Message; InformationBoard.SoundAlarm = True end if; The script calls the WidgetScanned python function: # pywip/functions.py from pywip.database import session from pywip.model import Widget, WidgetHistoryItem from pywip import validation, StatusMessage from datetime import datetime def WidgetScanned(widget_id, scanner_id): widget = session.query(Widget).get(widget_id) validation.validate_widget_passed_scanner(widget, scanner) # raises exception on error widget.history.append(WidgetHistoryItem(timestamp=datetime.now(), action=u"SCANNED", scanner_id=scanner_id)) widget.last_scanner = scanner_id widget.last_update = datetime.now() return StatusMessage("OK") # ... there are a dozen similar functions My question is: How do I best manage SQLAlchemy sessions in this scenario? The application server is a long-running process, typically running months between restarts. The application server is single-threaded. Currently, I do it the following way: I apply a decorator to the functions I make avaliable to the application server: # pywip/iasfunctions.py from pywip import functions def ias_session_handling(func): def _ias_session_handling(*args, **kwargs): try: retval = func(*args, **kwargs) session.commit() return retval except: session.rollback() raise return _ias_session_handling # ... actually I populate this module with decorated versions of all the functions in pywip.functions dynamically WidgetScanned = ias_session_handling(functions.WidgetScanned) Question: Is the decorator above suitable for handling sessions in a long-running process? Should I call session.remove()? The SQLAlchemy session object is a scoped session: # pywip/database.py from sqlalchemy.orm import scoped_session, sessionmaker session = scoped_session(sessionmaker()) I want to keep the session management out of the basic functions. For two reasons: There is another family of functions, sequence functions. The sequence functions call several of the basic functions. One sequence function should equal one database transaction. I need to be able to use the library from other environments. a) From a TurboGears web application. In that case, session management is done by TurboGears. b) From an IPython shell. In that case, commit/rollback will be explicit. (I am truly sorry for the long question. But I felt I needed to explain the scenario. Perhaps not necessary?)

  • Asp.net mvc, view with multiple updatable parts - how?

    - by DerDres
    I have started doing asp.net mvc programming and like it more everyday. Most of the examples I have seen use separate views for viewing and editing details of a specific entity. E.g. - table of music albums linking to separate 'detail' and 'update' views [Action] | Title | Artist detail, update | Uuuh Baby | Barry White detail, update | Mr Mojo | Barry White With mvc how can I achieve a design where the R and the U (CRUD) are represented in a single view, and furthermore where the user can edit separate parts of the view, thus limiting the amount of data the user can edit before saving? Example mockup - editing album detials: I have achieved such a design with ajax calls, but Im curious how to do this without ajax. Parts of my own take on this can be seen below. I use a flag (enum EditCode) indicating which part of the view, if any, that has to render a form. Is such a design in accordance with the framework, could it be done more elegantly? AlbumController public class AlbumController : Controller { public ActionResult Index() { var albumDetails = from ManageVM in state.AlbumState.ToList() select ManageVM.Value.Detail; return View(albumDetails); } public ActionResult Manage(int albumId, EditCode editCode) { (state.AlbumState[albumId] as ManageVM).EditCode = (EditCode)editCode; ViewData["albumId"] = albumId; return View(state.AlbumState[albumId]); } [HttpGet] public ActionResult Edit(int albumId, EditCode editCode) { return RedirectToAction("Manage", new { albumId = albumId, editCode = editCode }); } // edit album details [HttpPost] public ActionResult EditDetail(int albumId, Detail details) { (state.AlbumState[albumId] as ManageVM).Detail = details; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } // edit album thought [HttpPost] public ActionResult EditThoughts(int albumId, List<Thought> thoughts) { (state.AlbumState[albumId] as ManageVM).Thoughts = thoughts; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } Flag - EditCode public enum EditCode { NoEdit, Details, Genres, Thoughts } Mangae view <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication1.Controllers.ManageVM>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Manage </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Manage</h2> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Details) {%> <% Html.RenderPartial("_EditDetails", Model.Detail); %> <% }else{%> <% Html.RenderPartial("_ShowDetails", Model.Detail); %> <% } %> <hr /> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Thoughts) {%> <% Html.RenderPartial("_EditThoughts", Model.Thoughts); %> <% }else{%> <% Html.RenderPartial("_ShowThoughts", Model.Thoughts); %> <% } %>

  • How to echo if field is not found?

    - by Fahad
    Hi I'm trying to figure out how to echo back if the value entered does not match when a database lookup is done. I'm using ajax to run the request and php to do the lookup ajax.js: function showResult(str) { if (str=="") { document.getElementById("description").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("description").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getuser.php?voucher="+str,true); xmlhttp.send(null); } and getuser.php: <?php $q=$_GET["voucher"]; $con = mysql_connect('localhost', 'root', ''); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $sql="SELECT * FROM redemption WHERE voucher = '".$q."'"; $result = mysql_query($sql); echo "<table> <tr> <th>Name</th> <th>Product</th> <th>Address</th> <th>Status</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['product'] . "</td>"; echo "<td>" . $row['address'] ." ".$row['city'] ." ".$row['province'] ." ".$row['postal'] . "</td>"; echo "<td>" . $row['status'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> What I would like to do is that once the person enters an invalid or a voucher number that is not found I would like to return an error that "Voucher number is not found". There is also a column in the db that stores the status such as "redeemed" or "not redeemed". How could I check for both whether the voucher number exists and if it has already been redeemed? I assume it'd have to be a syntax such as $sql="SELECT * FROM redemption WHERE voucher = '".$q."'" AND status = 'not redeemed' and then use an else or case statement perhaps? Thanks in advance

  • 3D game engine for networked world simulation / AI sandbox

    - by Martin
    More than 5 years ago I was playing with DirectSound and Direct3D and I found it really exciting although it took much time to get some good results with C++. I was a college student then. Now I have mostly enterprise development experience in C# and PHP, and I do it for living. There is really no chance to earn money with serious game development in our country. Each day more and more I find that I miss something. So I decided to spend an hour or so each day to do programming for fun. So my idea is to build a world simulation. I would like to begin with something simple - some human-like creatures that live their life - like Sims 3 but much more simple, just basic needs, basic animations, minimum graphic assets - I guess it won't be a city but just a large house for a start. The idea is to have some kind of a server application which stores the world data in MySQL database, and some client applications - body-less AI bots which simulate movement and some interactions with the world and each other. But it wouldn't be fun without 3D. So there are also 3D clients - I can enter that virtual world and see the AI bots living. When the bot enters visible area, it becomes material - loads a mesh and animations, so I can see it. When I leave, the bots lose their 3d mesh bodies again, but their virtual life still continues. With time I hope to make it like some expandable scriptable sandbox to experiment with various AI algorithms and so on. But I am not intended to create a full-blown MMORPG :D I have looked for many possible things I would need (free and open source) and now I have to make a choice: OGRE3D + enet (or RakNet). Old good C++. But won't it slow me down so much that I won't have fun any more? CrystalSpace. Formally not a game engine but very close to that. C++ again. MOgre (OGRE3D wrapper for .NET) + lidgren (networking library which is already used in some gaming projects). Good - I like C#, it is good for fast programming and also can be used for scripting. XNA seems just a framework, not an engine, so really have doubts, should I even look at XNA Game Studio :( Panda3D - full game engine with positive feedback. I really like idea to have all the toolset in one package, it has good reviews as a beginner-friendly engine...if you know Python. On the C++ side, Panda3D has almost non-existent documentation. I have 0 experience with Python, but I've heard it is easy to learn. And if it will be fun and challenging then I guess I would benefit from experience in one more programming language. Which of those would you suggest, not because of advanced features or good platform support but mostly for fun, easy workflow and expandability, and so I can create and integrate all the components I need - the server with the database, AI bots and a 3D client application?

  • Actionscript multiple file upload, with parameter passing is not working

    - by Metropolis
    Hey everyone, First off, I am very bad at flash/actionscript, it is not my main programming language. I have created my own file upload flash app that has been working great for me up until this point. It uses PHP to upload the files and sends back a status message which gets displayed in a status box to the user. Now I have run into a situation where I need the HTML to pass a parameter to the Actionscript, and then to the PHP file using POST. I have tried to set this up just like adobe has it on http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html without success. Here is my Actionscript code import fl.controls.TextArea; //Set filters var imageTypes:FileFilter = new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg; *.jpeg; *.gif; *.png"); var textTypes:FileFilter = new FileFilter("Documents (*.txt, *.rtf, *.pdf, *.doc)", "*.txt; *.rtf; *.pdf; *.doc"); var allTypes:Array = new Array(textTypes, imageTypes); var fileRefList:FileReferenceList = new FileReferenceList(); //Add event listeners for its various fileRefList functions below upload_buttn.addEventListener(MouseEvent.CLICK, browseBox); fileRefList.addEventListener(Event.SELECT, selectHandler); function browseBox(event:MouseEvent):void { fileRefList.browse(allTypes); } function selectHandler(event:Event):void { var phpRequest:URLRequest = new URLRequest("ajax/upload.ajax.php"); var flashVars:URLVariables = objectToURLVariables(this.root.loaderInfo); phpRequest.method = URLRequestMethod.POST; phpRequest.data = flashVars; var file:FileReference; var files:FileReferenceList = FileReferenceList(event.target); var selectedFileArray:Array = files.fileList; var listener:Object = new Object(); for (var i:uint = 0; i < selectedFileArray.length; i++) { file = FileReference(selectedFileArray[i]); try { file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, phpResponse); file.upload(phpRequest); } catch (error:Error) { status_txt.text = file.name + " Was not uploaded correctly (" + error.message + ")"; } } } function phpResponse(event:DataEvent):void { var file:FileReference = FileReference(event.target); status_txt.htmlText += event.data; } function objectToURLVariables(parameters:Object):URLVariables { var paramsToSend:URLVariables = new URLVariables(); for(var i:String in parameters) { if(i!=null) { if(parameters[i] is Array) paramsToSend[i] = parameters[i]; else paramsToSend[i] = parameters[i].toString(); } } return paramsToSend; } The flashVars variable is the one that should contain the values from the HTML file. But whenever I run the program and output the variables in the PHP file I receive the following. //Using this command on the PHP page print_r($_POST); //I get this for output Array ( [Filename] => testfile.txt [Upload] => Submit Query ) Its almost like the parameters are getting over written or are just not working at all. Thanks for any help, Metropolis

  • How to use multiple instances of a usercontrol (with jquery) on the same page

    - by Julian
    Hi All, I've been working on an usercontrol with a jquery timer in it. At first I had the jquery within the usercontrol. But when I add 2 of those controls to my page the second usercontrol isn't showing it's data very well. Now I've put the jquery into the mainpage and the usercontrol only uses the id's of the jquery. Here is my usercontrol: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %> <style type="text/css"> #mainpanel { width: 145px; height: 123px; } </style> <div id="mainpanel"> <div> test</div> <div id="shortly" style="background-color: #FFFFFF"> </div> <button id="resetButton"> Reset </button> </div> Mainpage: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>hoi</title> <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <link href="Css/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script type="text/javascript" src="Scripts/jquery.countdown.js"></script> <script type="text/javascript"> $(document).ready(function () { $(function() { $("#mainpanel"); }); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown({ until: shortly, onExpiry: liftOff, layout: '{sn}', }); $('#resetButton').click(function () { $('#mainpanel').effect("highlight", {}, 700 ); $('#shortly').effect("highlight", {}, 700 ); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown('change', { until: shortly }); }); function liftOff() { // refresh the page window.location = window.location; } }); </script> </head> <body> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </body> </html> But still my usercontrols are acting weird, now my question is: "How can I make the SAME usercontrols work properly on ONE page?" Both of those use the same jquery code but the buttons etc. should only work within the usercontrol itself.

  • twitter bootstrap collapsable nav menu

    - by clifgray
    I am using twitter bootstrap on my web app to do all of the styling and everything is great for the most part. The problem is that my nav bar, once collapsed, will not drop down when I click the dropdown icon. I have listed my HTML but I think the problem is with my javascript seeing as this fiddle with the exact same code: http://jsfiddle.net/YWUmb/30/ works just fine. <div class="navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container"> <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a class="brand" href="/">Exployre</a> <div class="nav-collapse"> <ul class="nav"> <li><a href="/">Home</a></li> <li><a href="/profile">Profile</a></li> <li><a href="/sponsors">Sponsors</a></li> <li><a href="/working">Exployrers</a></li> <li><a href="/about">About</a></li> <li><a href="/share">Share</a></li> <li> {% if user %} User: {{ user }}<br> <a href="{{ logout }}">Logout</a> {% else %} <a href="/login">Signin or Register</a> {% endif %} <li> <a href="/profile"> {% if visits %} {% if visits > 10 %} Prestige: {{ visits }} {% elif visits > 5 %} {% endif %} {% endif %} </a> </li> <li> <form action="/search" class="navbar-search"> <div> <input type="text" placeholder="Search" class="search-query" name="q" size="55"/> </div> </form> <script type="text/javascript" src="http://www.google.com/coop/cse/brand?form=cse-search-box&amp;lang=en"></script> </li> </ul> </div><!--/.nav-collapse --> </div> </div> </div> <script type="text/javascript" src="/static/js/bootstrap.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> Is there anything wrong with my source code links or anything additional that I need to do to make it work?

  • jQuery dynamic field classes not being assigned as desired.

    - by Simon
    Hello, I'm working on a fancy login page with 4 unique states attributed through classes for each field (normal, focus, active-on, active-off). Normal is the default style. Focus is the focus style when nothing is typed. Active-on is the focus style when something has been typed. Active-off is for field that have user text in them, but are not focused right now. Here's a demo to help you understand what I'm doing: http://www.controlstack.com/login My JS is working almost correctly (thanks to some folks on this site), except in 2 cases: If I enter something in the username field, then tab over to the password field, it does not add the ".focus" class to the password field. If I blur out of the username field, then focus back on it, enter a few characters, then delete them, it does not add the ".focus" field.

  • IErrorHandler doesn't seem to be handling my errors in WCF .. any ideas?

    - by John Nicholas
    Have been readign around on IErrorHandler and want to go the config route. so, I have read the following in an attempt to implement it. MSDN Keyvan Nayyeri blog about the type defintion Rory Primrose Blog I have got it to compile and from the various errors i have fixed it seems like WCF is actually loading the error handler. My problem is that the exception that i am throwing to handle in the error handler doesn;t get the exception passed to it.

  • LibreOffice UNO Java API: how to open a document, execute a macro and close it?

    - by MarcoS
    I'm working on LibreOffice server-side: on the server I run soffice --accept=... Then I use Java LibreOffice client API's to apply a macro on a document (calc or writer). The java execution does not give any error, but I do not get the job done (macro code is executed, but it's effects are not in the output file). More, after macro script is invoked, the Basic debugger window appears, apparently stopped on the first line of my macro; F5 does not restart it... This is the relevant code I'm using: try { XComponentContext xLocalContext = Bootstrap.createInitialComponentContext(null); System.out.println("xLocalContext"); XMultiComponentFactory xLocalServiceManager = xLocalContext.getServiceManager(); System.out.println("xLocalServiceManager"); Object urlResolver = xLocalServiceManager.createInstanceWithContext( "com.sun.star.bridge.UnoUrlResolver", xLocalContext); System.out.println("urlResolver"); XUnoUrlResolver xUrlResolver = (XUnoUrlResolver) UnoRuntime.queryInterface(XUnoUrlResolver.class, urlResolver); System.out.println("xUrlResolve"); try { String uno = "uno:" + unoMode + ",host=" + unoHost + ",port=" + unoPort + ";" + unoProtocol + ";" + unoObjectName; Object rInitialObject = xUrlResolver.resolve(uno); System.out.println("rInitialObject"); if (null != rInitialObject) { XMultiComponentFactory xOfficeFactory = (XMultiComponentFactory) UnoRuntime.queryInterface( XMultiComponentFactory.class, rInitialObject); System.out.println("xOfficeFactory"); Object desktop = xOfficeFactory.createInstanceWithContext("com.sun.star.frame.Desktop", xLocalContext); System.out.println("desktop"); XComponentLoader xComponentLoader = (XComponentLoader)UnoRuntime.queryInterface( XComponentLoader.class, desktop); System.out.println("xComponentLoader"); PropertyValue[] loadProps = new PropertyValue[3]; loadProps[0] = new PropertyValue(); loadProps[0].Name = "Hidden"; loadProps[0].Value = Boolean.TRUE; loadProps[1] = new PropertyValue(); loadProps[1].Name = "ReadOnly"; loadProps[1].Value = Boolean.FALSE; loadProps[2] = new PropertyValue(); loadProps[2].Name = "MacroExecutionMode"; loadProps[2].Value = new Short(com.sun.star.document.MacroExecMode.ALWAYS_EXECUTE_NO_WARN); try { XComponent xComponent = xComponentLoader.loadComponentFromURL("file:///" + inputFile, "_blank", 0, loadProps); System.out.println("xComponent from " + inputFile); String macroName = "Standard.Module1.MYMACRONAME?language=Basic&location=application"; Object[] aParams = null; XScriptProviderSupplier xScriptPS = (XScriptProviderSupplier) UnoRuntime.queryInterface(XScriptProviderSupplier.class, xComponent); XScriptProvider xScriptProvider = xScriptPS.getScriptProvider(); XScript xScript = xScriptProvider.getScript("vnd.sun.star.script:"+macroName); short[][] aOutParamIndex = new short[1][1]; Object[][] aOutParam = new Object[1][1]; @SuppressWarnings("unused") Object result = xScript.invoke(aParams, aOutParamIndex, aOutParam); System.out.println("xScript invoke macro" + macroName); XStorable xStore = (XStorable)UnoRuntime.queryInterface(XStorable.class, xComponent); System.out.println("xStore"); if (outputFileType.equalsIgnoreCase("pdf")) { System.out.println("writer_pdf_Export"); loadProps[0].Name = "FilterName"; loadProps[0].Value = "writer_pdf_Export"; } xStore.storeToURL("file:///" + outputFile, loadProps); System.out.println("storeToURL to file " + outputFile); xComponent.dispose(); xComponentLoader = null; rInitialObject = null; System.out.println("done."); System.exit(0); } catch(IllegalArgumentException e) { System.err.println("Error: Can't load component from url " + inputFile); } } else { System.err.println("Error: Unknown initial object name at server side"); } } catch(NoConnectException e) { System.err.println("Error: Server Connection refused: check server is listening..."); } } catch(java.lang.Exception e) { System.err.println("Error: Java exception:"); e.printStackTrace(); }

  • If 'Architect' is a dirty word - what's the alternative; when not everyone can actually design a goo

    - by Andras Zoltan
    Now - I'm a developer first and foremost; but whenever I sit down to work on a big project with lots of interlinking components and areas, I will forward-plan my interfaces, base classes etc as best I can - putting on my Architect hat. For a few weeks I've been doing this for a huge project - designing whole swathes of interfaces etc for a business-wide platform that we're developing. The basic structure is a couple of big projects that consists of service and data interfaces, with some basic implementations of all of these. On their own, these assemblies are useless though, as they are simply intended intended as a scaffold on which to build a business-specific implementation (we have a lot of businesses). Therefore, the design of the core platform is absolutely crucial, since consumers of the system are not intended to know which implementation they are actually using. In the past it's not worked so well, but after a few proof-of-concepts and R&D projects this new platform is now growing nicely and is already proving itself. Then somebody else gets involved in the project - he's a TDD man who sees code-level architecture as an irrelevance and is definitely from the camp that 'architect' is a dirty word - I should add that our working relationship is very good despite this :) He's open about the fact that he can't architect in advance and obviously TDD really helps him because it allows him to evolve his systems over time. That I get, and totally understand; but it means that his coding style, basically, doesn't seem to be able to honour the architecture that I've been putting in place. Now don't get me wrong - he's an awesome coder; but the other day he needed to extend one of his components (an implementation of a core interface) to bring in an extra implementation-specific dependency; and in doing so he extended the core interface as well as his implementation (he uses ReSharper), thus breaking the independence of the whole interface. When I pointed out his error to him, he was dismayed. Being test-first, all that mattered to him was that he'd made his tests pass, and just said 'well, I need that dependency, so can't we put it in?'. Of course we could put it in, but I was frustrated that he couldn't see that refactoring the generic interface to incorporate an implementation-specific feature was just wrong! But it is all very Charlie Brown to him (you know the sound the adults make when they're talking to the children) - as far as he's concerned we don't need to worry about it because we can always refactor. The problem is, the culture of test-write-refactor is all very well and good - but not when you're dealing with a platform that is going to be shared out among so many projects that you could never get them all in one place to make the refactorings work. In my opinion, sometimes you actually have to think about what you're doing, and not just let nature take its course. Am I simply fulfilling the role of Architect as a dirty word here? I believe that architecture is important and should be thought about before code gets written; unless it's a particularly small project. But when you're working in a team of people who don't think that way, or even can't think that way how can you actually get this across? Is it a case of simply making the architecture off-limits to changes by other people? I don't want to start having bloody committees just to be able to grow the system; but equally I don't want to be the only one responsible for it all. Do you think the architect role is a waste of time? Is it at odds with TDD and other practises? Can this mix of different practises be made to work, or should I just be a lot less precious (and in so doing allow a generic platform become useless!)? Or do I just lay down the law? Any ideas/experiences/views gratefully received.

  • My Dijit DateTimeCombo widget doesn't send selected value on form submission

    - by david bessire
    i need to create a Dojo widget that lets users specify date & time. i found a sample implementation attached to an entry in the Dojo bug tracker. It looks nice and mostly works, but when i submit the form, the value sent by the client is not the user-selected value but the value sent from the server. What changes do i need to make to get the widget to submit the date & time value? Sample usage is to render a JSP with basic HTML tags (form & input), then dojo.addOnLoad a function which selects the basic elements by ID, adds dojoType attribute, and dojo.parser.parse()-es the page. Thanks in advance. The widget is implemented in two files. The application uses Dojo 1.3. File 1: DateTimeCombo.js dojo.provide("dojox.form.DateTimeCombo"); dojo.require("dojox.form._DateTimeCombo"); dojo.require("dijit.form._DateTimeTextBox"); dojo.declare( "dojox.form.DateTimeCombo", dijit.form._DateTimeTextBox, { baseClass: "dojoxformDateTimeCombo dijitTextBox", popupClass: "dojox.form._DateTimeCombo", pickerPostOpen: "pickerPostOpen_fn", _selector: 'date', constructor: function (argv) {}, postMixInProperties: function() { dojo.mixin(this.constraints, { /* datePattern: 'MM/dd/yyyy HH:mm:ss', timePattern: 'HH:mm:ss', */ datePattern: 'MM/dd/yyyy HH:mm', timePattern: 'HH:mm', clickableIncrement:'T00:15:00', visibleIncrement:'T00:15:00', visibleRange:'T01:00:00' }); this.inherited(arguments); }, _open: function () { this.inherited(arguments); if (this._picker!==null && (this.pickerPostOpen!==null && this.pickerPostOpen!=="")) { if (this._picker.pickerPostOpen_fn!==null) { this._picker.pickerPostOpen_fn(this); } } } } ); File 2: _DateTimeCombo.js dojo.provide("dojox.form._DateTimeCombo"); dojo.require("dojo.date.stamp"); dojo.require("dijit._Widget"); dojo.require("dijit._Templated"); dojo.require("dijit._Calendar"); dojo.require("dijit.form.TimeTextBox"); dojo.require("dijit.form.Button"); dojo.declare("dojox.form._DateTimeCombo", [dijit._Widget, dijit._Templated], { // invoked only if time picker is empty defaultTime: function () { var res= new Date(); res.setHours(0,0,0); return res; }, // id of this table below is the same as this.id templateString: " <table class=\"dojoxDateTimeCombo\" waiRole=\"presentation\">\ <tr class=\"dojoxTDComboCalendarContainer\">\ <td>\ <center><input dojoAttachPoint=\"calendar\" dojoType=\"dijit._Calendar\"></input></center>\ </td>\ </tr>\ <tr class=\"dojoxTDComboTimeTextBoxContainer\">\ <td>\ <center><input dojoAttachPoint=\"timePicker\" dojoType=\"dijit.form.TimeTextBox\"></input></center>\ </td>\ </tr>\ <tr><td><center><button dojoAttachPoint=\"ctButton\" dojoType=\"dijit.form.Button\">Ok</button></center></td></tr>\ </table>\ ", widgetsInTemplate: true, constructor: function(arg) {}, postMixInProperties: function() { this.inherited(arguments); }, postCreate: function() { this.inherited(arguments); this.connect(this.ctButton, "onClick", "_onValueSelected"); }, // initialize pickers to calendar value pickerPostOpen_fn: function (parent_inst) { var parent_value = parent_inst.attr('value'); if (parent_value !== null) { this.setValue(parent_value); } }, // expects a valid date object setValue: function(value) { if (value!==null) { this.calendar.attr('value', value); this.timePicker.attr('value', value); } }, // return a Date constructed date in calendar & time in time picker. getValue: function() { var value = this.calendar.attr('value'); var result=value; if (this.timePicker.value !== null) { if ((this.timePicker.value instanceof Date) === true) { result.setHours(this.timePicker.value.getHours(), this.timePicker.value.getMinutes(), this.timePicker.value.getSeconds()); return result; } } else { var defTime=this.defaultTime(); result.setHours(defTime.getHours(), defTime.getMinutes(), defTime.getSeconds()); return result; } }, _onValueSelected: function() { var value = this.getValue(); this.onValueSelected(value); }, onValueSelected: function(value) {} });

  • Dynamic model choice field in django formset using multiple select elements

    - by Aryeh Leib Taurog
    I posted this question on the django-users list, but haven't had a reply there yet. I have models that look something like this: class ProductGroup(models.Model): name = models.CharField(max_length=10, primary_key=True) def __unicode__(self): return self.name class ProductRun(models.Model): date = models.DateField(primary_key=True) def __unicode__(self): return self.date.isoformat() class CatalogItem(models.Model): cid = models.CharField(max_length=25, primary_key=True) group = models.ForeignKey(ProductGroup) run = models.ForeignKey(ProductRun) pnumber = models.IntegerField() def __unicode__(self): return self.cid class Meta: unique_together = ('group', 'run', 'pnumber') class Transaction(models.Model): timestamp = models.DateTimeField() user = models.ForeignKey(User) item = models.ForeignKey(CatalogItem) quantity = models.IntegerField() price = models.FloatField() Let's say there are about 10 ProductGroups and 10-20 relevant ProductRuns at any given time. Each group has 20-200 distinct product numbers (pnumber), so there are at least a few thousand CatalogItems. I am working on formsets for the Transaction model. Instead of a single select menu with the several thousand CatalogItems for the ForeignKey field, I want to substitute three drop-down menus, for group, run, and pnumber, which uniquely identify the CatalogItem. I'd also like to limit the choices in the second two drop-downs to those runs and pnumbers which are available for the currently selected product group (I can update them via AJAX if the user changes the product group, but it's important that the initial page load as described without relying on AJAX). What's the best way to do this? As a point of departure, here's what I've tried/considered so far: My first approach was to exclude the item foreign key field from the form, add the substitute dropdowns by overriding the add_fields method of the formset, and then extract the data and populate the fields manually on the model instances before saving them. It's straightforward and pretty simple, but it's not very reusable and I don't think it is the right way to do this. My second approach was to create a new field which inherits both MultiValueField and ModelChoiceField, and a corresponding MultiWidget subclass. This seems like the right approach. As Malcolm Tredinnick put it in a django-users discussion, "the 'smarts' of a field lie in the Field class." The problem I'm having is when/where to fetch the lists of choices from the db. The code I have now does it in the Field's __init__, but that means I have to know which ProductGroup I'm dealing with before I can even define the Form class, since I have to instantiate the Field when I define the form. So I have a factory function which I call at the last minute from my view--after I know what CatalogItems I have and which product group they're in--to create form/formset classes and instantiate them. It works, but I wonder if there's a better way. After all, the field should be able to determine the correct choices much later on, once it knows its current value. Another problem is that my implementation limits the entire formset to transactions relating to (CatalogItems from) a single ProductGroup. A third possibility I'm entertaining is to put it all in the Widget class. Once I have the related model instance, or the cid, or whatever the widget is given, I can get the ProductGroup and construct the drop-downs. This would solve the issues with my second approach, but doesn't seem like the right approach.

  • mediaelement.js control sizes are wrong when clip nested in a hidden element

    - by Martin Francis
    It's a nasty one this. In an audio control placed within a container element whose display property is initially set to none, the audio clip does NOT correctly size the progress bar when it is initialised. This is clear when the container's display property is changed from 'none' to '' (which is equivalent to 'static'). But who would ever do that? I make extensive use of 'tabbed' display arrangements on community sites like this one: http://www.churchesInBracebridge.ca Owing to the page arrangement, the audio controls which you see under 'sermons' (which at the time of writing still using Flash rather than John's excellent library here) are initially rendered in a div that is hidden. Simplified Test case Rather than have anyone have to wade through all of that, here's a much simplified test case: http://jsfiddle.net/sJL6T/36 Here's the full page source for those who'd prefer to work with it that way. <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>MediaElementPlayer.js</title> <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="http://mediaelementjs.com/js/mejs-2.13.1/mediaelement-and-player.js"></script> <link rel="stylesheet" href="http://mediaelementjs.com/js/mejs-2.13.1/mediaelementplayer.css" /> <script type="text/javascript"> function toggle(id){ document.getElementById(id).style.display= (document.getElementById(id).style.display=='none' ? '' : 'none'); } </script> </head> <body> <h1>MediaElementPlayer.js</h1> <h2 onclick="return toggle('test1')">Initially Hidden (Click to toggle)</h2> <div id='test1' style='display:none'> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <h2 onclick="return toggle('test2')">Initially Shown (Click to toggle)</h2> <div id='test2' style=''> <audio controls="controls"> <source src="http://mediaelementjs.com/media/AirReview-Landmarks-02-ChasingCorporate.mp3" type="audio/mp3" /> </audio> </div> <script> $('audio').mediaelementplayer(); </script> </body> </html> Possible Workarounds Now I know that Google maps has the same quirk and there are two possible ways I've used to deal with that: Use absolute positioning in a displayed div to place the element 10,000px to the left then bring it onto the stage when we want to see it Have the map pane displayed when loading then hide it as soon as it's loaded (ugly I know, but it usually works) However either approach would be a pain to do, as I have a lot of legacy code using the simpler div hiding method. I know that JQuery can get the dimensions of an element event if it is hidden - someone thoughtfully fiddled that and it does work: http://jsfiddle.net/sJL6T/9 Perhaps it may be possible to modify the actual library to find correct dimensions, even if the container itself is hidden? That would be wonderful, if it can be done! Initial experiments on mediaelement-and-player.js code I found that when I provided a fixed value in the setControlsSize function for railWidth, I got consistent results with both controls in the test case above (and obviously I'm working with my own copy of the library to do that, not the one stored at mediaelementjs.com): // outer area rail.width(railWidth); Change to this: // outer area railWidth=216; rail.width(railWidth); Many thanks in anticipation!
