• Visual Basic VB6 calling a C# dll

  Hi all, I am trying to call a c# dll from VB6. I could able to add the refernece for the dll but I am not able to access the methods of the dll. What could be the reason I registered the dll using the regasm and .tlb is also generated. If any one could help me. Regards, Santha This is because C# will create a .NET CLass Library and not a COM Class Library. VB6 knows only about COM Class Libraries. So if you have the C# project you can make it a COM DLL's which then would be visible to VB6. ...Show All

• Software Development for Windows Vista How to use DirectShow in a multithreaded application

  Dear DirectShow forum, When I call functions related to the filter graph from a different thread than the one the filter graph was created on, strange things happen (functions cause errors or do not return). How can I use DirectShow in a multithreaded application P.S. I am using DirectShowNet in the C# language. Thank you! wtrn Hi LGS, I have found the cause of the problem! You could not have known the problem without my source code. Blocking in the SG callback as per my previous thread has some side-effects which I had not considered. SetPositions does not return because the callback function is blocking. I don't know why this problem does not occur when SetPositions is called from the same thread the gr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA with Windows Forms - Game does not stay active

  I programmed my own FormsGraphicsComponent like this: public class FormsGraphicsComponent : IGraphicsDeviceService , IGraphicsDeviceManager , IDisposable {   public FormsGraphicsComponent( Game game, IntPtr renderWindowHandle)   {     ...   }   ... } Then used a standard windows form as a base, placed a Panel on it, that I exposed as a property of the form.

• Windows Forms DataGridView - Copy only selected text

  Hi there. I am having an annoying problem with a DataGridView not linked to any database; I save/load to/from a simple XML file. (Using VSNet 2005 release version - developping in VB.NET) When editing a cell's content, highlighting a portion of text and pressing CTRL-C, the complete cell content is copied to the clipboard.

• SQL Server RMO Replication problems with Pull Subscriptions

  Hello, I have the following situation. I have a single publication on my publisher Server. This publication is created using SQL Server Manager. Snapshot is created completly.

• Software Development for Windows Vista FindFirstUrlCacheEntry and COOKIE_CACHE_ENTRY

  Hi, I'm trying to enumerate the cookies on a user's machine and present them to the user along with the associated cookie information. Using the FindFirstURLCacheEntry(Ex) and FindNextURLCacheEntry(Ex) API functions I can do this successfully in Win XP (and in Win XP with IE7 installed so it does not appear to be an IE7 issue). After having looked at the msdn entry for these functions they are listed as supported in Vista but, despite having cookies on my machine and confirming as much by looking in the cookies directory, these functions are not listing out the cookies. Is there a new API to retrieve them or is Vista storing the information differently or are they just flagged differently and it hasn't been documented Any he ...Show All

But it hangs as soon as I create a new project.

The problem still persists. 3) Right now, my VC++ Express install fails to install the MSDN Express Edition component. 4) Even after closin ...Show All

• Visual Basic Code Snippets

  As I was trying to create my own snippets, I added two new ones to the database folder. Now I cannot access this folder from VB 2005 Express. Besides, I created a new folder and added a snippet. I can see the folder but when I try to get the snippet, the system says that I do not have any. Hi, Have you tried selecting ALL FILES view in the OPEN File/Project window If not each file should end with "dot vb" as in >> my_Code_Snippet_For_An_Example_Class.Vb Each "dot vb" file is simply a text file so you should be able to load it into Notepad, WordPad or Word.
