• Visual Basic vb.net listbox item count issue

  I use a listBox on VB.NET (VS.NET 2005) and pass the listbox's handle to a C function for item population. Within the C function I use SendMessage() with LB_INSERTSTRING to insert item into the listbox, as in SendMessage((HWND)hWnd, LB_INSERTSTRING, lIndex, (LPARAM) ((LPCSTR) item_to_be_inserted)); After the above call, I can verify the listCount is correct within the C function using LB_GETCOUNT, as in listCount = SendMessage((HWND)hWnd, LB_GETCOUNT, (WPARAM) 0, (LPARAM) ((LPCSTR)0)); The problem is when execution returns to VB.NET, the listCount from VB.NET via listBox.Items.Count() always returnes a value of 0. This s ...Show All

• Visual C++ compiler generates incorrect code /w all optimizations disabled

  I have encountered, twice now, cases where the VS2005 C++ compiler generates incorrect x86 code. I have a small boyer-moore implementation that I can send to anyone interested that demonstrates one of these cases. Actually, I'll post it as a reply to this.. Simply re-arranging the code (no functional difference) fixes the errata. Below are copies from the Visual Studio debugger, showing the incorrect code.. then a simple adjustment that resulted in generation of correct code. Again, optimizations disabled. The conditonal jump instruction missing below is very essential, as this branch is taken the majority of the time. INCORRECTLY GENERATED ...Show All

• Visual Basic VB6

  Hi It's been a while since I've done any VB programming, and I need to get back in to it for work purposes. I've quite a bit of experience at VB 6 programming and have lots of code and examples that I need to use again. Is the latest VB development package backwards compatible with VB6 I'm sure all of these questions have already been answered so appologies for that. Thanks John VB.Net is NOT backwards compatible with VB6...there will be a small learning curve tranfering over to .NET....the curve is primarily learning the namespaces and classes...with the exception of a few new keywords and a few t ...Show All
