• Problem using custom HttpHandler to process requests for both .aspx and non-extension pages in IIS7

  - by Noel

  I am trying to process both ".aspx" and non-extension page requests (i.e. both contact.aspx and /contact/) using a custom HttpHandler in IIS7. My handler works just fine in either one case or the other, but as soon as I try to process both cases, it only works for one. Please see Handlers snippet from my web.config below: If i keep only mapping to "*.aspx" then all .aspx requests are processed correctly, but obviously extensionless requests won't work: <add name="AllPages.ASPX" path="*.aspx" verb="*" type="Test.PageHandlerFactory, Test" preCondition="" /> If i change the mapping to "*" then all extensionless requests are processed correctly, but ".aspx" requests that should still be handled by this handler stop working. Note that i added the StaticFiles entry in order to process files that are on disk like images, css, js, etc. <add name="WebResource" path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader" /> <add name="StaticFiles" verb="GET,HEAD" path="*.*" type="System.Web.StaticFileHandler" resourceType="File" /> <add name="AllPages" path="*" verb="*" type="Test.PageHandlerFactory, Test" preCondition="" /> The crazy thing is that when i load an ".aspx" request (with the 2nd configuration shown) IIS7 gives a 404 not found error. The error also says that the request is processed by the StaticFiles handler. But I made sure to add resourceType="File" to the StaticFileHandler in order to avoid this. According to MS this means the request is only for "physical files on disk". Am i misreading/interpreting the "on disk" part? My .aspx file isn't on disk, that's why i want to use the handler in the first place.

• JQueryUI with Google's CDN help

  - by TenaciousImpy

  Hi, I'm having trouble loading JQueryUI from Google's CDN. I've got an ASP.NET application that and am using this to call the scripts: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js" type="text/javascript"></script> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/ui-darkness/jquery-ui.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> $(function() { $("#accordion").accordion(); }); </script> </asp:Content> I then have a test accordion: <div id="accordion"> <h3><a href="#">First header</a></h3> <div>First content</div> <h3><a href="#">Second header</a></h3> <div>Second content</div> </div> However, this doesn't work. I used Chrome's Dev tool and I get this error: Uncaught Error: The 'accordion' plugin requires Sys.scripts.ExtendedAccordion to be loaded with a call to Sys.require() first I'm also using MS' Ajax CDN in my masterpage, so could that be causing a problem? Thanks

• Replacing/Extending Visual Studio's Generate Stub in Visual Studio 2010

  - by devoured elysium

  When we write the name of a method that doesn't exist, Visual Studio 2010 asks us if we'd like to generate a method stub with that name. What I'd like to know if is it possible to replace that same code stub generating command with one made by myself. I never did any kind of extensibility programming for Visual Studio so I have a couple of questions: How hard is it? Is it something I can learn in a couple of nights, or is it something that'll make me "lose" a lot of time? It seems to me that there isn't a lot of support for that kind of programming, as generally people are not that interested in developing solutions that extend the Visual Studio IDE. I searched on SO and it doesn't appear to have many threads about extending Visual Studio. I don't know how the generate method stub thing works in Visual Studio, but I just wanted to turn it into something a bit more flexible and useful. Has anyone dealt with these kind of things before, that can give me a pointer to where to start? I know of MS VSX site but that has a lot of resources and can be overwhelming for someone new to the subject as I am. What technology will I need to use? T4? Maybe I'll need to know a lot about the code, like Visual Studio does, so I can know other method's type arguments, names, etc. Is that what T4 is for? Thanks

• display sqlite datatable in a jtable

  Hi I'm trying to display an sqlite data table in a jtable but i have an error " sqlite is type forward only" how could I display it in a jtable try { long start = System.currentTimeMillis(); Statement state = ConnectionBd.getInstance().createStatement( ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY ); ResultSet res = state.executeQuery("SELECT * FROM data"); ResultSetMetaData meta = res.getMetaData(); Object[] column = new Object[meta.getColumnCount()]; for(int i = 1 ; i <= meta.getColumnCount(); i++){ column[i-1] = meta.getColumnName(i); } res.last(); int rowCount = res.getRow(); Object[][] data = new Object[res.getRow()][meta.getColumnCount()]; res.beforeFirst(); int j = 1; while(res.next()){ for(int i = 1 ; i <= meta.getColumnCount(); i++) data[j-1][i-1] = res.getObject(i); j++; } res.close(); state.close(); long totalTime = System.currentTimeMillis() - start; result.removeAll(); result.add(new JScrollPane(new JTable(data, column)), BorderLayout.CENTER); result.add(new JLabel("execute in " + totalTime + " ms and has " + rowCount + " ligne(s)"), BorderLayout.SOUTH); result.revalidate(); } catch (SQLException e) { result.removeAll(); result.add(new JScrollPane(new JTable()), BorderLayout.CENTER); result.revalidate(); JOptionPane.showMessageDialog(null, e.getMessage(), "ERREUR !

• Seeking reporting or templating tool to generate large formatted PDF reports from dataset

  - by Mr. Tacos

  Say I have some data in MySQL or a big ole CSV file. I also have a report. It's a PDF, call it 100 pages long. I need to generate variations on this PDF for slices of the data. More specific example: I have a CSV file with each StackOverflow user in a row and each column contains various statistics about that user. I have a report called "Your StackOverflow Performance". Its got lots of text, always the same, but each section contains something like: "You Vs. The Average StackOverflow Poster on this metric". I want a table that appears there that has the average data, which is the same in every run of the PDF, in one column. In the second column, I want your data, which is different for each PDF/row in the CSV file/user of StackOverflow. I'm pretty sure people use things like Crystal for this? Is there something in MS SQL Server that's good for this? An open source template language? I'm not even really sure if what I need is called a 'reporting' tool (since I don't really need to do any crunching, the data in this case is being crunched by a series of scripts and SPSS, I don't need bands and subbands and so on) or 'templating'. Is there even such a thing as templating PDFs? Natch, I'd be fine with something that generates output easily scriptable to PDF, like eps, but not something like HTML. The report formatting is fussy and done and externally determined and handed down from on high. It's print-oriented, not webby. Thanks in advance.

• Hg: How to do a rebase like git's rebase

  - by jpswain09

  Hey guys, In Git I can do this: 1. Start working on new feature: $ git co -b newfeature-123 # (a local feature development branch) do a few commits (M, N, O) master A---B---C \ newfeature-123 M---N---O 2. Pull new changes from upstream master: $ git pull (master updated with ff-commits) master A---B---C---D---E---F \ newfeature-123 M---N---O 3. Rebase off master so that my new feature can be developed against the latest upstream changes: (from newfeature-123) $ git rebase master master A---B---C---D---E---F \ newfeature-123 M---N---O I want to know how to do the same thing in Mercurial, and I've scoured the web for an answer, but the best I could find was this: http://www.selenic.com/pipermail/mercurial/2007-June/013393.html That link provides 2 examples: 1. I'll admit that this: (replacing the revisions from the example with those from my own example) hg up -C F hg branch -f newfeature-123 hg transplant -a -b newfeature-123 is not too bad, except that it leaves behind the pre-rebase M-N-O as an unmerged head and creates 3 new commits M',N',O' that represent them branching off the updated mainline. Basically the problem is that I end up with this: master A---B---C---D---E---F \ \ newfeature-123 \ M'---N'---O' \ newfeature-123 M---N---O this is not good because it leaves behind local, unwanted commits that should be dropped. The other option from the same link is hg qimport -r M:O hg qpop -a hg up F hg branch newfeature-123 hg qpush -a hg qdel -r qbase:qtip and this does result in the desired graph: master A---B---C---D---E---F \ newfeature-123 M---N---O but these commands (all 6 of them!) seem so much more complicated than $ git rebase master I want to know if this is the only equivalent in Hg or if there is some other way available that is simple like Git. Thanks!! Jamie

• How to dispatch a new property value in an object to the same property of two other objects

  - by WPFadvocate

  In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects. Edited: here is my tentative code for multibinding, with the false hope that it would work without additional code: // create the multibinding MultiBinding mb = new MultiBinding() { Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }; // create individual bindings to associate object_2 and object_3 to object_1 Binding b2 = new Binding() { Source = object_2, Path = new PropertyPath("X") }; Binding b3 = new Binding() { Source = object_3, Path = new PropertyPath("X") }; // add individual bindings to multibinding mb.Bindings.Add(b2); mb.Bindings.Add(b3); // bind object_2 and _3 to object_1 BindingOperations.SetBinding(object_1, TypeObject_1.XProperty, mb); But actually, there is a runtime error, saying the binding set by the last instruction is lacking a converter. But again I don't know how to write this converter (there is nothing to convert (as this is the case in the related MS sample of code linking 3 rgb properties to a color property), only to forward the value of the property changed to the two other properties). I understand I could solve the problem by creating an X_Changed event in the 3 types and then have each object registering to the two other objects event. I don't like this "manual" way and would prefer to bind the 3 properties together.

• SQL Server, how to join a table in a "rotated" format (returning columns instead of rows)?

  - by Joshua Carmody

  Sorry for the lame title, my descriptive skills are poor today. In a nutshell, I have a query similar to the following: SELECT P.LAST_NAME, P.FIRST_NAME, D.DEMO_GROUP FROM PERSON P JOIN PERSON_DEMOGRAPHIC PD ON PD.PERSON_ID = P.PERSON_ID JOIN DEMOGRAPHIC D ON D.DEMOGRAPHIC_ID = PD.DEMOGRAPHIC_ID This returns output like this: LAST_NAME FIRST_NAME DEMO_GROUP --------------------------------------------- Johnson Bob Male Smith Jane Female Smith Jane Teacher Beeblebrox Zaphod Male Beeblebrox Zaphod Alien Beeblebrox Zaphid Politician I would prefer the output be similar to the following: LAST_NAME FIRST_NAME Male Female Teacher Alien Politician --------------------------------------------------------------------------------------------------------- Johnson Bob 1 0 0 0 0 Smith Jane 0 1 1 0 0 Beeblebrox Zaphod 1 0 0 1 1 The number of rows in the DEMOGRAPHIC table varies, so I can't say with certainty how many columns I need. The query needs to be flexible. Yes, it would be trivial to do this in code. But this query is one piece of a complicated set of stored procedures, views, and reporting services, many of which are outside my sphere of influence. I need to produce this output inside the database to avoid breaking the system. Any ideas? This is MS SQL Server 2005, by the way. Thanks.

• Lua task scheduling

  - by Martin

  I've been writing some scripts for a game, the scripts are written in Lua. One of the requirements the game has is that the Update method in your lua script (which is called every frame) may take no longer than about 2-3 milliseconds to run, if it does the game just hangs. I solved this problem with coroutines, all I have to do is call Multitasking.RunTask(SomeFunction) and then the task runs as a coroutine, I then have to scatter Multitasking.Yield() throughout my code, which checks how long the task has been running for, and if it's over 2 ms it pauses the task and resumes it next frame. This is ok, except that I have to scatter Multitasking.Yield() everywhere throughout my code, and it's a real mess. Ideally, my code would automatically yield when it's been running too long. So, Is it possible to take a Lua function as an argument, and then execute it line by line (maybe interpreting Lua inside Lua, which I know is possible, but I doubt it's possible if all you have is a function pointer)? In this way I could automatically check the runtime and yield if necessary between every single line.

• Using ServletOutputStream to write very large files in a Java servlet without memory issues

  - by Martin

  I am using IBM Websphere Application Server v6 and Java 1.4 and am trying to write large CSV files to the ServletOutputStream for a user to download. Files are ranging from a 50-750MB at the moment. The smaller files aren't causing too much of a problem but with the larger files it appears that it is being written into the heap which is then causing an OutOfMemory error and bringing down the entire server. These files can only be served out to authenticated users over https which is why I am serving them through a Servlet instead of just sticking them in Apache. The code I am using is (some fluff removed around this): resp.setHeader("Content-length", "" + fileLength); resp.setContentType("application/vnd.ms-excel"); resp.setHeader("Content-Disposition","attachment; filename=\"export.csv\""); FileInputStream inputStream = null; try { inputStream = new FileInputStream(path); byte[] buffer = new byte[1024]; int bytesRead = 0; do { bytesRead = inputStream.read(buffer, offset, buffer.length); resp.getOutputStream().write(buffer, 0, bytesRead); } while (bytesRead == buffer.length); resp.getOutputStream().flush(); } finally { if(inputStream != null) inputStream.close(); } The FileInputStream doesn't seem to be causing a problem as if I write to another file or just remove the write completly the memory usage doesn't appear to be a problem. What I am thinking is that the resp.getOutputStream().write is being stored in memory until the data can be sent through to the client. So the entire file might be read and stored in the resp.getOutputStream() causing my memory issues and crashing! I have tried Buffering these streams and also tried using Channels from java.nio, none of which seems to make any bit of difference to my memory issues. I have also flushed the outputstream once per iteration of the loop and after the loop, which didn't help.

• Using Regex Replace when looking for un-escaped characters

  - by Daniel Hollinrake

  I've got a requirement that is basically this. If I have a string of text such as "There once was an 'ugly' duckling but it could never have been \'Scarlett\' Johansen" then I'd like to match the quotes that haven't already been escaped. These would be the ones around 'ugly' not the ones around 'Scarlett'. I've spent quite a while on this using a little C# console app to test things and have come up with the following solution. private static void RegexFunAndGames() { string result; string sampleText = @"Mr. Grant and Ms. Kelly starred in the film \'To Catch A Thief' but not in 'Stardust' because they'd stopped acting by then"; string rePattern = @"\\'"; string replaceWith = "'"; Console.WriteLine(sampleText); Regex regEx = new Regex(rePattern); result = regEx.Replace(sampleText, replaceWith); result = result.Replace("'", @"\'"); Console.WriteLine(result); } Basically what I've done is a two step process find those characters that have already been escaped, undo that then do everything again. It sounds a bit clumsy and I feel that there could be a better way.

• "User Friendly" .net compatible Regex/Text matching tools?

  - by Binary Worrier

  Currently in our software we provide a hook where we call a DLL built by our clients to parse information out of documents we are processing (the DLL takes in some text (or a file) and returns a list of name/value pairs). e.g. We're given a Word doc or Text file to Archive. We do various things to the file, and call a DLL that will return "pertinent" information about the file. Among other things we store that "pertinent" data for posterity. What is considered "pertinent" depends on the client and the type of the document, we don't care, we get it and store it. I've been asked to develop a user friendly "something" that will allow a non-programmer user to "configure" how to get this data from a plain text document (<humor>The user story ends with the helpful suggestion/query "We could use regex for this?"</humor>) It's safe to assume that a list of regex's isn't going to cut this, I've written some of these parsers for customers, the regex's to do these would be hedious and some of them can't be done by regex's. Also one of the requirements above is "user friendly" which negates anything that has users seeing or editing regex expressions. As you can guess, I don't have a fortune of time to do this, and am wondering is there anything out there that I can plug in to our app that has a nice front end and does exactly what I need? :) No? Whadda mean no! . . . sigh Ok then failing that, anything out there that "visually" builds regex's and/or other pattern matching expressions, and then allows one to run those expressions against some text? The MS BRE will do what I want, but I need something prettier that looks less like code. Thanks guys,

• VMWare steals IP addresses [closed]

  - by Ishan Amin

  I'm having a peculiar problem, that I think I have narrowed down to VMware. For the past one year, every once in a while we lose internet connection and not all users (about 10 users) go down at the same time, its usually one-by-one. First someone will call me and say "Internet is down" and then we would go reset the router and modem and switch and it would be working again for a while, then go down again without any pattern or replicatable sequence. We'd go repeat the steps again to get everyone in the office running again. We called our Internet Service Provider and they constantly say, We see your modem and we see your router and from thier end everything is OK. we replaced our router and switch and modem, twice! Last friday, it dawned upon me, that everytime we turn on a VMware machine, this sequence of taking everyone down starts, which also explains the message that my users get for "IP Conflict Found" So we do alot of VMware testing and lo and behold, it takes my Internet down. My Yahoo and Gtalk would continue working but www is down when the VMware machines are started. I do use bridged networking to all the VMware machines, but I dont know what else to set it at. now, sorry for this long rambling but anyone have any clue on how to stop this? thanks IA

  I am working on a school project that uses ASP.NET. I found this TextEditor control ( http://blogs.msdn.com/kirti/archive/2007/11/10/rich-text-editor-is-here.aspx ) that I am trying to include but it isn't working. The error I am getting is: Error Rendering Control - TextEditor. An unhandled exception has occurred. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I see this error when I go Design part of the editor. I just don't understand this error at all. Also I am a lil bit confused as there is no parameter called index. :( What I have done is reference the binary in my project and then on the page I am trying to use it have registered its namespace and assembly with this line: <%@ Register Assembly="RichTextEditor" Namespace="AjaxControls" TagPrefix="rtt" %> I then go ahead and try to add the control to the page with this line of code: <rtt:richtexteditor ID="TextEditor" Theme="Blue" runat="server" /> Any help would be much appreciated.

• Svn import with auto-props & pre-commit hook

  - by James Tisato

  My company's svn repo has a lot of MS Word docs in it. We've implemented a policy that all .doc files must have the svn:needs-lock property set to prevent parallel access on files that are hard to merge (we've also done this for xls, ppt, pdf etc.). We've implemented the policy by distributing a svn config with auto-props set appropriately for all relevant document types. We've also set up a pre-commit hook that checks that all added files of these types have the needs-lock property set (i.e. if they forget/are too lazy to update their svn config file, they won't be able to add any docs to the repo). The problem I'm having, however, is that the pre-commit hook fails when users try to import files into the repo, e.g. some users like to add files directly thru TortoiseSVN's Repo Browser, which effectively is an svn import. Through testing on other file types, I have seen that doing an import does in fact apply the auto-props listed in my config, but they don't seem to be applied at the point that the pre-commit hook runs. When importing .doc files, the hook fails, saying that the needs-lock property is missing. Is there really much difference between adding a single file to a working copy and committing it vs importing a file directly? Do we need to tailor our precommit hook in some way to cater for this scenario?

• Embedding Perl Interpreter

  - by cam

  Hi, just downloaded ActivePerl. I want to embed the perl interpreter in a C# application (or at least call the perl interpreter from C#). I need to be able to send send out data to Perl from C#, then receive the output back into C#. I just installed ActivePerl, and added MS Script Control 1.0 as a reference. I found this code on the internet, but am having trouble getting it to work. MSScriptControl.ScriptControlClass Interpreter = new MSScriptControl.ScriptControlClass(); Interpreter.Language = @"ActivePerl"; string Program = @"reverse 'abcde'"; string Results = (string)Interpreter.Eval(Program); return Results; Originally, it had 'PerlScript' instead of 'ActivePerl', but neither work for me. I'm not entirely sure what Interpreter.Language expects. Does it require the path to the interpreter? Solved... I'm not sure how, but when I changed it back to PerlScript it works now. Still, I would like to know if MSScript Control is using ActivePerl or another interpreter.

• Architecting iPhone Views - seeking help on a specific issue + general advice

  - by Ev

  Hi there, I am a web developer (rails, python) that is new to iPhone development. I've done some desktop development in the past within the MS environment (C#). I'm trying to build a really simple iPhone application and I am confused by the way that views work in general. If someone can provide advice for my particular problem, along with some resources where I can learn how to architect iPhone views in the future, that would be awesome. I feel like a lot of the Apple documentation that I've come across is too specific - I am lacking a fundamental understanding of how views work on the iPhone. My particular problem looks like this: I need one view that displays some downloaded text content. This is the view that shows when the app loads, and it is pretty straightforward. Then I need a settings area (I've already decided I don't want to use the iPhone settings area). The settings area main page will have some text fields on it. It will also have a 2-row grouped table. Each cell in that table will take you to another view which also has a grouped table used for multi-select. I suspect that I can reuse the same view for these two final "detailed setting" views. In summary: home page settings main page detailed setting 1 detailed setting 2 Any help and advice appreciated.

• Which parts of Sharepoint do I need to understand to build a publicly facing website?

  - by Petras

  I am building a publicly facing website that does the following. Users log in. And then view a list of their customers. They click on a customer to view their past purchases, order them, change them etc. This is not a shopping site by the way. It is a simple look up tool. Note that none of the data accessed by the website is in anything other than a SQL database - no office documents. Also, the login does not use users Windows credentials on a VPN or something like that. Typically I would build this using a standard ASP.NET MVC website. However the client says they want to use Sharepoint. As I understand it, Sharepoint is used for workflow and websites that are collaboration tools such as the components you can see here http://www.sharepointhosting.com/sharepoint-features.html Here are my questions: Would I be right in saying that WSS is completely inappropriate for this task as it comes with an overhead that provides no benefits? If I had to use it, would I need WSS or MOSS? If I had to use it, would I be right in saying the site would consist of : List item a) Web Parts b) And a custom site layout. How do I create one of these?

• Save email as draft in php

  - by Yorian

  Hello, The past few days I've been trying to find out how I can save emails as drafts using php. I've created an emailaddress that uses imap (and resides on the same server). What I would like to do is to use php to create an email and store it in the drafts folder. These emails would then be recognized by the email client (ms office outlook in this case) so they can be editted and send from the email client. I've found some interesting information about the imap functions from php, they let you send mail, but I can't really figure out how to store them in the drafts folder (to which I have write access). I can actually find and read the emails, I save as drafts in my email client, using my ftp connection. However they make use of UID and message-ID's and such which I don't understand where they come from. My questions: - how could I create email drafts - How does a new UID or message-ID get created, and how would I use them for my email-draft file? Help is much appreciated, thanks. Yorian

• How can I get the Name of the Program associated with a file extension using Delphi?

  - by lkessler

  I need to get the name of the program currently associated with a file extension for the current user. If you right-click on a file and select properties, then what I need is the program name that is to the right of the "Opens with" line. e.g. For ".xls", I want to be able to get the answer "Microsoft Office Excel", or whatever program the user has as their default program to open .xls files. I have determined it's not as easy as just going into HKEY_CLASSES_ROOT and picking it out, since it may also be specified in HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER or HKEY_USERS. Maybe all I need to know is the pecking order used by Windows to determine this and how to get to each of the locations. Of course, a Windows API call to do this would be ideal. This is a similar question to: How to get icon and description from file extension using Delphi? but that question only answered how to get the description of the extension and the icon of the associated program. I couldn't find a way to extend that to also get the name of the associated program.

• How to create a high quality icon for my Windows application?

  - by Patrick Klug

  If you are running Windows with a higher DPI setting you will notice that most application icons on the desktop look terrible. Even high profile application icons such as Google Chrome look terrible while for example Firefox, Skype and MS Office icons look sharp: (example) I suspect that most icons look blurry because a lower resolution icon is scaled up rather than using a higher resolution icon. I want to give my application a high quality icon and can't seem to convince Windows to use the higher resolution icon. I have created a multi-resolution icon with the free icon editor IcoFX. The icon is provided in 16x16, 24x24, 32x32,48x48, 128x128 and 256x256 (!) (all in 32 bit including alpha channel) yet Windows seems to use the 128x128 version of the icon on the desktop and scale it up which looks terrible. (I am using Windows 7 - 64 bit - the icon is placed by means of setting up a shortcut in the msi (created via Visual Studio 2008 Setup Project) and pointing it to the .ico file that contains the multi-resolution icon) I have tried removing the 128x128 icon but to no avail. Interestingly in Windows Explorer the icon looks great even when using the Extra Large Icon setting. How can I create a high quality desktop icon that looks great on higher DPI settings on Windows?

• How to refactor this database to allow sync. with smart clients?

  - by Anton Zvgny

  Howdy, I have inherited the following database: http://i46.tinypic.com/einvjr.png (EDIT: I cannot post images, so here goes the link) This currently runs 100% online thru an Asp.Net web app , but some employees will need to have offline access to this database to either get documents or to insert new documents for later synchronization when back to the office. What changes need to be made to this database scheme to support such scenario (sync smart clients with central web database)? Thanks! ps. I'm not an developer/dba, i'm just an mechanic engineer tasked with changing this app, so, take it easy on me :D ps1. We're using MSSQL Server for the online central database and MSSQL Compact for the smart client. ps2. the ImageGuid field of the images table is used to save the images to the file system. The web app takes the guid and create folders according to the first 3 initial letters to persist the image to the file system. ps3. The users of the smart client not always get server data first and then go modifying to sync later the changes. Most of the time they start working completely offline (with a blank local database) and later sync the data to the server. ps4. All the users of the smart client app have an account at the web app.

• How can I run a local Windows Application and have the output be piped into the Browser.

  I have Windows Application (.EXE file is written in C and built with MS-Visual Studio), that outputs ASCII text to stdout. I’m looking to enhance the ASCII text to include limited HTML with a few links. I’d like to invoke this application (.EXE File) and take the output of that application and pipe it into a Browser. This is not a one time thing, each new web page would be another run of the Local Application! The HTML/java-script application below has worked for me to execute the application, but the output has gone into a DOS Box windows and not to pipe it into the Browser. I’d like to update this HTML Application to enable the Browser to capture that text (that is enhanced with HTML) and display it with the browser. <body> <script> function go() { w = new ActiveXObject("WScript.Shell"); w.run('C:/DL/Browser/mk_html.exe'); return true; } </script> <form> Run My Application (Window with explorer only) <input type="button" value="Go" onClick="return go()"> </FORM> </body>

• Sharepoint designer is replacing french characters with &#65533;

  - by chris

  First of all, I'm not a web designer, I'm a programmer, so I'm working a bit out of my knowledge area. However, as the person in my office who has some working knowledge of French, I'm stuck with this issue. The Problem: Sharepoint Designer is replacing all French accented characters with the &#65533; (square box or diamond-? �) character. It doesn't appear to matter if I enter the 'é' character as alt-130 (in either design or source or as &eacute; Everything works fine when editing, but when the file is saved and loaded into a browser, it replaces the characters. When reloading into designer, the file shows the 65533 symbol. EDIT: More info. I use &#233; and save, close SP designer, Reloading SP designer will show the é (instead of the code) in source. Next reload will have replaced it with &#65533; Question 1: (more important) HOW DO I STOP THIS!? Question 2: (more interesting) Why does this happen? Charset is iso-8859-1

• How do I detect whether the sample supplied by VideoSink.OnSample() is right-side up?

  - by Ken Smith

  We're currently using the Silverlight VideoSink to capture video from users' local webcams, kinda like so: protected override void OnSample(long sampleTime, long frameDuration, byte[] sampleData) { if (FrameShouldBeSubmitted()) { byte[] resampledData = ResizeFrame(sampleData); mediaController.SetVideoFrame(resampledData); } } Now, on most of the machines that we've tested, the video sample provided in the byte[] sampleData parameter is upside-down, i.e., if you try to take the RGBA data and turn it into, say, a WriteableBitmap, the bitmap will be upside-down. That's odd, but fairly easy to correct, of course -- you just have to reverse the array as you encode it. The problem is that at least on some machines (e.g., the single Macintosh in our test environment), the video sample provided is no longer upside-down, but right-side up, and hence, flipping the image actually results in an image that's received upside-down on the far side. I reported this to MS as a bug, but their (terse) response was that it was "As Designed". Further attempts at clarification have so far been ignored. Now, I'll grant that it's kinda entertaining to imagine the discussions behind this design decision: "OK, just to make it interesting, let's play the video rightside up on a Mac, but let's turn it upside down for Windows!" "Great idea!" "Yeah, that'll keep those developers guessing!" But beyond that, I can't find this, umm, "feature" documented anywhere, nor can I find any documentation on how one is supposed to be able to tell that a given video sample is upside down or rightside up. Any thoughts on how to tell this?
