• Visual Studio Team System Changesets and Labeling

  I'm trying to get familiar with the source control functionality in TFS before we migrate over from VSS. One thing I'm having trouble wrapping my head around is labeling. I can label a project, but I can't find anyway to find what label a changeset belongs to. I'm used to looking at the history of a project and then doing a "get" on the label. Thanks. Have you tried the Find Label dialog Beyond that, there isn't really a feature like you're asking for. Brian's blog has the short reason why: http://blogs.msdn.com/bharry/archive/2005/11/18/494439.aspx We're looking at improving the UI for la ...Show All

• SQL Server Paging Header and Detail

  I would like to create a report with header and detail, like an invoice with invoice # and line items. I'd like the invoice # to come from a summary query that breaks 1 invoice # per page. Then I'd like to display the line items below the invoice # on each page, from a second query passing the invoice number as a parameter. How is this done Do I need a subreport ie: header from summary query: invoice 101 detail from detail query passed invoice # = 101: line 1 item A line 2 item B line 3 item C page header from summary query: invoice 102 detail from detail query passed invoice # = 102: line 1 i ...Show All

• SQL Server 64bit problem?

  I run SQL Server 2005 on a Windows 2003 64-bit server. I have created a package where I run an execute t-sql statement task. In the t-sql I have the following: select * from OpenDataSource('Microsoft.Jet.OLEDB.4.0','Data Source="c:\test.mdb";User ID=Admin;Password=').pubs.dbo.data and I get the following error: The OLE DB provider "Microsoft.Jet.OLEDB.4.0" has not been registered.

• Visual Basic Using a Registry Launch Condition to Specify a Target Directory does not work

  I am trying to use VS deployment as per http://msdn.microsoft.com/library/default.asp url=/library/en-us/vsintro7/html/vxtskusingregistrysearchtospecifytargetdirectory.asp but it does not work as intended. I have logged the installation failure.The launch condition seems to be evaluated after the target directory is formed so [INSTALLATIONPATH] retrieved from the registry is empty when it is supposed to be applied via DefaultDirectory in my custom folder.

• Visual C# vs2003 vs. vs2005

  I noticed when I create a new Windows Application in visual studio 2005 it creates a file Form1.Designer.cs which is all of the generated code, and seperately there is a another file form1.cs which is what I suppose is for me to add code to Both of these files are partial classes But only form1.cs is public. Why the change from vs2003 where all this was in one file Tyler Perkins Visual Basic 2005 and Visual C# 2005 have come with a new feature called partial classes that enables classes to be extended across multiple files. As you've already noticed, the Visual Studio project system has made use of this a ...Show All

• Windows Forms Inheritance and designers

  I have a class 'SyntaxBox' which extends richTextBox to do some rudimentry syntax highlighting. How do I determine what designer richTextBox uses inorder to inherit it The thing that I usually do is check reflector. Reflector is a little program that disassembles .NET so you can browse the managed code. It can be found here . In reflector, search for System.Windows.Forms.RichtTextBox. You can do that by simple searching the tree or using the Find function (looking glass). From there, right click the class and select 'Disassemble'. You see the RichTextBox class definitiion there with all the attributes. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. how to create an 8 bit raw file?

  Hi every one. Does anyone know how to create an 8 bit raw file from a bitmap The idea is to generate landscapes from those raw files and also to automatically generate the raw and then create the terrain. Thanks in advance. Cubaconn Instead of completely RAW format, I'd advise using the PGM format (or PPM if you need RGB rather than just an 8 bit value). You can find details of the PGM format at: http://www.wotsit.org/search.asp page=6&s=graphics The binary form of PGM is exactly the same as a RAW file, except it has the addition of a very simple ASCII header describing the contents of the file; ha ...Show All

• Windows Forms ListBox question -- is there an 'ItemAdded' event or similar?

  I need to do some processing whenever an item is added (or indeed removed, so changes generally) to a listbox. From a cursory glance at the documentation I do not find relevant events. I would be grateful however if anyone could point out that I am missing something. Or do I have to add a custom event If so, if anyone has code that could get me started I would again be very grateful. Thanks. There is no event or protected method that is invoked when the items change. There are a couple of alternatives however. The first option is to use a DataSource or BindingSource and handle the events within these object ...Show All
