• PHP controllable menubar position

  - by craide

  I'm an admin for a page and I want to give certain users dynamic control of the menubar layout. The ideal would be a page with a list with menu items and arrows pointing up and down with each item and when you click them the item is reordered. I have a pretty basic idea of how I can do it but I would like some suggestions. The items are stored in MySQL and I only need help figuring out how the items should be ordered or numbered and how to re-order them. This probably needs some javascript trickery and I'm not familiar with JS.

• Caching HTML output with PHP

  - by Mohamed Amine

  Hi! I would like to create a cache for my php pages on my site. I did find too many solutions but what I want is a script which can generate an HTML page from my database ex: I have a page for categories which grabs all the categories from the DB, so the script should be able to generate an HTML page of the sort: my-categories.html. then if I choose a category I should get a my-x-category.html page and so on and so forth for other categories and sub categories. I can see that some web sites have got URLs like: wwww.the-web-site.com/the-page-ex.html even though they are dynamic. thanks a lot for help

• ASP.NET MVC. Hot to guess autogenerated id value ?

  - by Andrew Florko

  My web form contains list of dynamic fields that are generated like this: <% for (int i = 0; i < Model.Options.Count; i++) { %> ... <%= Html.Hidden("Options[" + i + "].Id", Model.Options[i].Id)%> <%= Html.CheckBox("Options[" + i + "].Selected", Model.Options[i].Selected)%> ... This maps perfectly on array of controller method parameters as described in Model Binding To A List article. I want to add label for checkboxes to title them, but I have to guess their ids in hmtl layout. Options[" + i + "].Selected turns into Options_0__Selected How can I avoid hardcoding Id generation in-built asp.net mvc rules? Thank you advance.

• js regexp problem

  - by Alexander

  I have a searching system that splits the keyword into chunks and searches for it in a string like this: var regexp_school = new RegExp("(?=.*" + split_keywords[0] + ")(?=.*" + split_keywords[1] + ")(?=.*" + split_keywords[2] + ").*", "i"); I would like to modify this so that so that I would only search for it in the beginning of the words. For example if the string is: "Bbe be eb ebb beb" And the keyword is: "be eb" Then I want only these to hit "be ebb eb" In other words I want to combine the above regexp with this one: var regexp_school = new RegExp("^" + split_keywords[0], "i"); But I'm not sure how the syntax would look like. I'm also using the split fuction to split the keywords, but I dont want to set a length since I dont know how many words there are in the keyword string. split_keywords = school_keyword.split(" ", 3); If I leave the 3 out, will it have dynamic lenght or just lenght of 1? I tried doing a alert(split_keywords.lenght); But didnt get a desired response

• Drupal - Getting node id from view to customise link in block

  - by hfidgen

  I got a little problem with Drupal (again) in that I'm trying to work out how I can build a block which is able to show the node ID of the view page the block is currently sitting on. I'm using views to build a large chunk of my site, but I need to be able to make "intelligent" blocks in PHP mode which will have dynamic content depending on what the view is displaying. So.. how can I go about finding the $nid which a view is currently displaying?! Any ideas?

• Custom Parser for JQuery Tablesorter

  - by Tim

  I'm using the jQuery Tablesorter and have an issue with the order in which parsers are applied against table columns. I'm adding a custom parser to handle currency of the form $-3.33. $.tablesorter.addParser({ id: "fancyCurrency", is: function(s) { return /^\$[\-]?[0-9,\.]*$/.test(s); }, format: function(s) { s = s.replace(/[$,]/g,''); return $.tablesorter.formatFloat( s ); }, type: "numeric" }); The problem seems to be that the built-in currency parser takes precedence over my custom parser. I could put the parser in the tablesorter code itself (before the currency parser) and it works properly, but this isn't very maintainable. I can't specify the sorter manually using something like: headers: { 3: { sorter: "fancyNumber" }, 11: { sorter: "fancyCurrency" } } since the table columns are generated dynamically from user inputs. I guess one option would be to specify the sorter to use as a css class and use some JQuery to explicitly specify a sorter like this question suggests, but I'd prefer to stick with dynamic detection if possible.

• How to test reliability of my own (small) embedded operating system ?

  - by TridenT

  I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

• Need help in using Eclipse JEE version to develop a servlet project

  - by michael

  Hi, I have downloaded eclipse jee version (3.5) and I would like to use it to develop a servlet project on tomcat. So I * install tomcat and add it as my server in my eclipse environment. * create a Dynamic Web Project called 'TestServlet' * create a new servlet called 'MainServlet' and then I deploy my project to the tomcat server via eclipse and 'run the server in debug' mode. But when I use the browser to hit 'http://localhost:8080/TestServlet/MainServlet' I see no resource found (that page is generated by Tomcat, so I know my Tomcat is running). Can you please tell me what am I missing? Or how can I trouble shoot my problem? I think it must be some path /name is not set correctly.

• Compiling Qt for Windows 98

  - by wrp

  I need to support Windows 98. The Qt documentation claims this is possible, but there are no instructions. The distributed binaries don't run on Win98 and the majority of Qt applications I have sampled also don't. For several apps that do run on 98, I have asked authors how they did it, but the common answer is that it was accidental and they don't know what factors caused it. In searching the forums for help, I found only guesses that turned out to be wrong. For example, one belief is that to compile for Win9x, you must build the tools and the apps on that platform. Yet, things I found to run were built on newer versions of Windows. What is required to build the Qt dev tools and then applications for Win98? How about cross-compiling from WinXP or Linux? Are there specific components that can't be made to run on Win98? Are there particular difficulties with dynamic or static linking for Win98 support?

• Correct model for a database with a table for each user.

  - by BAH

  Kinda stuck here... I have an application with lets say 5000 rows of data per user and was wondering if it was right or wrong to do it this way: On user account creation a new table is created (UserData_[UserID]) or should I just have 1 table for userdata and have everything in there with a column for userid? The reason I am stuck at the moment is that it seems NHibernate isn't able to be mapped to dynamic table names without creating another ISessionFactory which has alot of overhead AFAIK. Any help would be greatly appreciated. Thanks.

• backslashes in url variables

  - by namtax

  Hi there I have set up my coldfusion application to have dynamic urls on the page, such as www.musicExplained/index.cfm/artist/:VariableName However my variable names will sometimes contain backslashes, such as www.musicExplained/index.cfm/artist/GZA/Genius This is causing a problem, because my application presumes that the slash in the variable name represents a different section of the website, the artists albums. So the URL will fail. I am wondering if there is anyway to prevent this from happening? Do I need to use a function that replaces slashes in the variable names with another character? Thanks

• Does .NET have a linker?

  - by Water Cooler v2

  From Jon Skeet's blog: What does the following comment mean? // The line below only works when linked rather than // referenced, as otherwise you need a cast. // The compiler treats it as if it both takes and // returns a dynamic value. string value = com.MakeMeDynamic(10); I understand what referencing an assembly is. You may reference it when compiling the program files either using the /ref: switch at the command line or you may add a statically reference to the assembly in Visual Studio. But how do you link to an assembly in .NET? Does he mean, load the assembly using Reflection (Assembly.LoadFile())? Or, the Win32 API LoadLibrary()? Or, does .NET have a linker that I have never heard of?

• How do I dynamically specify a file in DOS?

  - by donde

  I am trying to use c# in .net to run dos commands to ftp a a file. Technically, it calls a BAT file which calls a CMD file which executes the DOS code. It was up to the CMD file. The CMD fiel will work if I hardcode the path, but I need to dynamically specify the path of the file. BAT File... ftp.exe -s:%~dp0\mycmdfile.cmd And in the cmd file... open <my ost> <my user name> <my pw> quote site cyl pri=1 sec=1 lrecl=1786 blksize=0 recfm=fb retpd=30 put <here is where I need the dynamic path> + localfilename remotefilename quit

• How to select elements from a set that are children of another element

  - by Tatu Ulmanen

  Hi, The title is a bit confusing but here's what I'm after: I have a set of elements containing all the h3 elements in a page. In jQuery terms: var mySet = $('h3'). I also have an div element var myContainer = $('div#foo') I need to find all items in the set mySet that are children of myContainer. Any ideas? I bet there's some magical one liner for this but I cannot think of any. I'd rather not loop through every element in the set manually and use .closest(myContainer) or something like that to determine the relationship. Note that in my scenario, I cannot use a new selector like $('div#foo h3') (that would be too easy) as I don't have access to the actual selector values. So it has to be dynamic.

• How to tell the MinGW linker not to export all symbols?

  - by James R.

  Hello, I'm building a Windows dynamic library using the MinGW toolchain. To build this library I'm statically linking to other 2 which offer an API and I have a .def file where I wrote the only symbol I want to be exported in my library. The problem is that GCC is exporting all of the symbols including the ones from the libraries I'm linking to. Is there anyway to tell the linker just to export the symbols in the def file? I know there is the option --export-all-symbols but there seems not to be the opposite to it. Right now the last line of the build script has this structure: g++ -shared CXXFLAGS DEFINES INCLUDES -o library.dll library.cpp DEF_FILE \ OBJECT_FILES LIBS -Wl,--enable-stdcall-fixup EDIT: In the docs about the linker it says that --export-all-symbols is the default behavior and that it's disabled when you don't use that option explicitly if you provide a def file, except when it doesn't; the symbols in 3rd party libs are being exported anyway. EDIT: Adding the option --exclude-libs LIBS doesn't keep their symbols from being exported either.

• Why does derivative trading position always require C++ knowledge?

  - by Jeffrey

  I’ve never worked in trading environment before and I was curious to see that few of the trading houses seem to use C# but most of them do heavily rely on C++. Why is it? Is it because C++ is better performance wise? Is it because of legacy code base? Is it because cross platform issue? What about dynamic languages (ruby, python)? Are they too slow for this kind of work in terms of performance? Updated: If realibility and performance are important would "Erlang" be the "next big thing" in trading platform?

• Guice expert question

  - by Roman

  Hi All I am wondering if someone would be such an expert in guice that he even would know how to implement that : I have an injection annotation (@ConfParam)with some parameters , like that : class TestClass { private final int intValue; @Inject public TestClass(@ConfParam(section = "test1", key = "1") int intValue{ this.intValue = intValue; } public int getIntValue() { return intValue; } } The ConfParam is my custom annotation. Now , when the injection value is requested , I would like guice to create a dynamic binding, to resolve the value. For that binding I will need the parameters inside the annotation. Some example could be , I will have to look in the database in some table where the section is ? and the key is ?. All the trouble is that the data is not available when the injector is created and could be also be added at runtime. Ps. I static solution is easy. ( just have a look at the Names class)

• How to position columns in select list based on a variable.

  - by Rohit

  I am creating a dynamic grid which is created by selecting the format defined in the below XML.My select list includes all columns in this XML,I want to position these columns columns on the basic of position attribute in XML. <gridFormat> <column property="CustomerID" dbName="CustName" HeaderText="Customer" IsVisible="0" Position="1" /> <column property="CustomerName" dbName="FacilityName" HeaderText="Facility" IsVisible="1" Position="3" /> <column property="FacilityInternalID" dbName="Pname" HeaderText="Patient" IsVisible="1" Position="2" /> </gridFormat> I cannot select them in the order specified by the position attribute. I can do it in C# by looping around the returned datatable and specifically position columns using datatable.columns.setordinal() method. Is there any better way in SQL or C# to accomplish this.

• clearcase option for view movement from one host path to another

  - by wrapperm

  Hi all, I have created a clearcase dynamic view for my development by name "view1". I have mistakenly selected the view storage location as a local PC in my network, that was made sharable by the PC owner. I was suppose to select the view storage location to be a server. Now, the issue is that I have done lot of development with the view that I have created and have plenty of view DO's and view private files in it. So I'm ruling out the option of deleting the view from the PC local storage (host path) and then creating another view in the server with the same config spec. Please, let me know if there is any method of editing the view properties (or doing something else) by which I could be able to move the view to the server (with all the DO's and view private files retained) Thanks in advance, Rahamath

• How to learn Ruby on Rails as a complete Programming Beginner?

  - by Alex

  I want to build a scalable dynamic Web Application. I have never programmed an Object Oriented language before. Or, let's just say I am completely new to programming, because the previous experiences aren't worth talking about. I know I have a really big task ahead of me ^^ but I wanted to get into coding for the last 10 years and now that I'm finally doing it, I would like to know how to get there in the most efficient way. Any good books/tutorials you could recommend? Would it really make sense to learn other, better documented languages before learning RoR? Or would it be better for a beginner to learn C# with ASP.NET first? Thank you for your help in advance ;-)

• What's the best way to share one Entity Framework 4 data model among multiple applications (meant to

  - by Ivan

  A project (a "solution" to say in VS terms) of mine consists of an ASP.Net 4 Dynamic Data Entities web application, some WinForms applications, some WPF applications, some services. All they are intended to work with one SQL Server database, generated from an Entity Framework 4 model as table-per-type, with lots of inheritance and multiple self-referencing relations. Where do I best put my model? In a separate class library, a copy in every project, in one project, etc. What naming should I best use? Is it good idea to name it MySolution.MyClassLibrary.MySolutionEntities, or just MySolutionEntities or just MySolution? Can you share any useful experience on this subject?

• Bootstrap Modal & rails remote

  - by Kevin Brown

  Using this bootstrap modal extension and animate.css for fun, how can I take a make an easy ajax modal using :remote => true to fill in the modal box? Also, how would I use the bootstrap modal default "submit/cancel" buttons to interact with a form that's loaded? I'm looking for a more dynamic solution instead of hard-html-ing every modal into the page or using a bunch of jquery ajax calls for each dialog. I've done a few quick searches, but they've turned up nil for this particular solution.
