• Visual Studio 2008 (Pre-release) installation and VS setup script succeed, but still no IDE support

  I've done LINQ installation on several other occasions and have never encountered this problem. I was trying to install LINQ on a new machine running SBS 2003. The installation was successful. I then ran the IDE setup script which also succeeded. However, when I opened an existing MS solution which has several DLINQ projects in VS 2005, the new C# 3.0 syntax is not being recognized. And I didn't get the usual C# 3.0 warning when the project was loaded as I had expected. The compilation, however, was able to succeed because the LINQ build target was included in the project file of these existing projects. But I could not create a new LINQ project. I went to the VS template directory and no template zip fi ...Show All

• Windows Forms move focus to next control,whaterver that control is--> at Form's level

  I have many control in the windows form, some are custom controls from different "programming way". How can I set a method to change focus from one control to next one, when you hit enter key, so you actually have a controls ring including buttons, listbox, textbox, ... thanks in advance for your help, Edward On buttons, to get the enter key, I think you also have to create your own button and override ProcessDialogKey or ProcessCmdKey: http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.processdialogkey.aspx http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.processcmdkey(VS.80).aspx - Charlie ...Show All

• Software Development for Windows Vista LoadXml() causes bizarre error

  I'm attempting to load an internal XmlDocument in a WF class using doc.LoadXml(string). I keep getting the "Compilation Failed. Exception has been thrown by the target of the invocation" error when I build. I've narrowed it down to that single line of code, and what's even crazier, is that the following line will build doc.LoadXml("<test/>"); whereas doc.LoadXml("test"); will throw the error at compile-time. The real code, though, was trying to load a string property on the class. public string OrderDocument { get { if (this._orderDocument == null) { this._orderDocument = new XmlDocument(); this._orderDocument. ...Show All

• Visual Studio Team System Tracking requirements, scenarios & tasks through iterations

  I think I know the answer to this question having read some of the answers on this forum...but I'd like to make sure I have this is clear in my mind. In the MSF for CMMI process there are requirements, scenarios and tasks (plus other work items). In a development there will be multiple iterations to develop various features of the system. I would like to be able to track a requirement to its implementation in one or more of the iterations. I'm assuming that I would analyse the requirements to create scenarios and link them together (e.g. "customer creates wibble" and "customer views wibble history" being two scenarios that fufil the "customer's can manage their wibbling" requirement). From the scenarios ...Show All

• Visual Studio 2008 (Pre-release) Cascade delete support ?

  Hi, I've hit a problem concerning cascade deletes on foreign keys in SQL. I have in my 'noddy' app again a contact with many address emails . This is managed via a ContactAddressEmail table. This table has a unique PK and corresponding non-nullable FKs. Now I've marked the foreign key betwen Contact and ContactAddressEmail as 'Cascade' for the Delete Rule on the relation. Same for the AddressEmail and ContactAddressEmail relation. When testing in TSQL this is fine - any Contact I delete results in the associated ContactAddressEmail record being removed. Likewise for the AddressEmail record. Magic. However, in LINQ when I db.Contacts.Remove(c), I get a problem as the non-null constraint fires. Why is the cascade not firing f ...Show All

• Visual Studio Express Editions How to convert char string to Unicode?

  Hi -- I'm looking for a simple way to convert an ASCII string to Unicode. More specifically, I've got a function that starts out... int main (int argc, char *argv[]) And I need argv[1] converted to Unicode because I want to feed that string (it's a file name) to a Win32 API call SetNamedSecurityInfoW, which requires a filename (logically) but needs it in Unicode. I have tried using MultiByteToWideChar, but it doesn't like my argv[1]. Any help would be much appreciated.

Many thanks. ...Show All

• Visual Studio Team System No backslahes in regular expressions for work item rules? (MATCH pattern attribute)

  I attempted to write a regular expression to disallow backslashes in work item titles. It looks like this in the work item type definition XML: <FIELD name="Title" refname="System.Title" type="String"> <MATCH pattern="^[^\\]*$"/><!--disallows backslashes--> </FIELD> However, the server rejects it: Xml validation error at row 11, column 13: The 'pattern' attribute is invalid - The value '^[^\\]*$' is invalid according to its datatype 'http://schemas.microsoft.com/VisualStudio/2005/workitemtracking/typelib:NonEmptyPlainConstant' - The Pattern constraint failed. Looking up the "Non empty plain constant" in typelib.xsd, I can see that backslashes are prohibited! <!-- Non-empty plain constant --> ...Show All

• Visual Studio Custom Project Item Templates

  Hello everyone, I am developing a new project wizard, and from it I am trying to use an existing project item from a template I created that is working fine. The problem I have is when I call GetProjectItemTemplate from the solution2 object, I get: The system cannot find the file specified. (Exception from HRESULT: 0x80070002) So, I started testing some things, and replaced my call for the custom template with a call to a microsoft supplied template, class.zip: string classTemplate = soln2.GetProjectItemTemplate("class", " csharp" ); I found that this works just fine. However, if i replace "class" with another microsoft supplied template, Form for instance: string classTemplate = soln2. ...Show All

• .NET Development Object Allocation Performance

  I have been implementing a geometrical algorithm in C#. The algorithm performs boolean operation on triangle meshes of arbitrary size. This implies that meshes sometimes get rather large (500,000-1,000,000 triangles) and as a result a lot of objects need to be allocated (triangles and vertices of the mesh). The allocation seems to be the primary bottle neck of the algorithm, instead of the very large amount of arithmetic computations. So my question is if there is any way to fasten or tweak the allocation of such a large amount of objects (avoiding the managed heap by using structs is of course not an option as the vertices are not unique for each triangle neither are triangle adjacencies). Pre-allocat ...Show All

• SQL Server How to change configured value for the ServerName property of a Connection via DTEXEC
