• Software Development for Windows Vista Breakpoints not working

  I'm running the February CTP on WinXP SP2 and Visual Studio Pro. I'm running my development environment inside of a Virtual PC VM. The problem that I'm having is that I can create workflows fine, but breakpoints set up on a workflow activity do not work. I see the hollow circle with the warning when running in debug mode. Breakpoints set on the code beside code such as a CodeActivity handler work. I've looked at the other posts on the forum about the same problem, but the solution doesn't appear to be valid for my issue. I'm not running workflows from another library. I've built a console application and have the workflows in the conso ...Show All

• Visual Studio Understanding Check Out Behavior

  VS.NET 2003 and VSS 6.0d build 31222 Occasionally if I try to simply view the designer for some of my VSS protected ASP.NET pages, I am prompted for checkout. I am not explicitly selecting checkout, however - just "View Designer" from the context sensitive menu in my project pane. When the checkout window comes up, I have options to either Check Out, or Edit, the file. I also have an alert symbol that reads "Editing items in memory without checking them out can cause loss of data". So I'll check it out, despite the fact that I do not intend to make any changes to the page. This is an annoyance than anything since ...Show All

• Visual C# Unloading an Assembly

  Hello, I read in one of the Blogs that an Assembly cannot be unloaded. It has to be loaded into a AppDomain and then unloaded. I have tried that. Take a look at the following code. AppDomain newDomain = AppDomain.CreateDomain("NewDomain"); Assembly myAssembly = newDomain.Load(AssemblyName.GetAssemblyName(assemblyPath); After doing Reflection on myAssembly, I used AppDomain.Unload(newDomain); There are a some other statements in the CurrentDomain. While executing, Iam getting the following exception: 'System.Runtime.Seri ...Show All

• SQL Server Maybe I'm asking for too much.

  I’m using oracle but I’m sure this problem will have similar solution to SQL. I have a list of string in a table (aa, bb, cc, dd). I also have a list of numbers that are not in the database. What I’m looking for is an output like this. Aa, 11 Aa, 22 Bb, 11 Bb, 22 Cc, 11 Cc, 22 Dd, 11 Dd, 22 Is this possible, without having to insert the numbers in a database table and with a simple query (this could be done with temporary table) Sure...   SELECT    YourTable.YourStringColumn,    N.Number FROM YourTable CROSS JOIN (   SEL ...Show All

• .NET Development request.BeginGetRequestStream with FTP in ACTIVE mode problem.

  Hi, i'm making an asynchronous upload function. When using .usepassive = true all is good, i can transfer and catch pretty much every exception thrown at it. When using .usepassive = false and the server and client are both configured properly, all is good too. The problem i have is when .usepassive = false and either the ftp or client are not configured properly to use active ftp connections. Here is the code that calls the BeginGetRequestStream request.BeginGetRequestStream(New AsyncCallback(AddressOf EndGetStreamCallback), state) waitObject.WaitOne() After BeginGetRequestStream is used and EndGetStreamCa ...Show All

• Visual Basic Displaying list of text in a TextBox

  I'm a novice programmer and I have a very basic question. I am trying to display text in a TextBox, with one caveat. I need to be able to insert "carriage returns" or force the text onto a new line. I am using the text box to display the results of a numbered list.

Thank you for any help you can provide. ''If it were me I would make the textbox multi line then do somethin ...Show All

• Visual Studio Problems getting the VCCLCompilerTool object!

  Hi I'm writing some (C#) code to modify the compiler settings on a large number of VC++ projectfiles and I'm having trouble getting the VCCLCompilerTool object. My code looks something like this: VCConfiguration CurrentConfig = <some code to get the config> VCCLCompilerTool Compiler = (( IVCCollection )CurrentConfig.Tools).Item( "VCCLCompilerTool" ) as VCCLCompilerTool ; Now, the Item method returns some object, but the cast to VCCLCompilerTool fails. If I change VCCLCompilerTool to VCLinkerTool everything works as expected and I get a VCLinkerTool object. Is there ANY way to figure out what kind of ...Show All
