I've been presented with an architectural challenge and am looking for ideas. Customer has an existing win32 native application that they are pretty resistant to changing in any but trivial ways. It is written in unmanaged c++ and uses at least one 3rd party dll so it is not a stand alone exe. What it is doesn't matter much, think of it...

Hi! Is there a way to get a notification that a thread no longer runs (has returned) in your application? I know this is possible in kernel mode (using PsSetCreateThreadNotifyRoutine), but is there a way to know this from user mode, using only Win32 API ? The problem is that I can't control the code in the thread, because my module i...

I have a very shallow idea of .NET and C#/C++.NET. I've used it a few times to create some simple, stand-alone apps. From my simplistic viewpoint, I look at it as another "framework", eg. layer, on top of the OS that can be used to write apps for. Can someone shed some more light on what its limitations are and when it is most useful? I...

I'm fairly new to Windows programming. I'm doing a simple launcher app for WinCE using VC++ (not MFC). So far I've created the basic interface and buttons and stuff. I just wanted to know the best way to launch an external application when the user clicks the button (on BN_CLICKED). I found some methods such as ShellExecute, CreateProce...
I have an application that message-loops using MsgWaitForMultipleObjects to catch additional events while pumping ui messages. It seems that as soon as a window is being moved or resized, DefWindowProc begins it's own message loop until the mouse is being released. This situation prevents from the outer loop to catch the additional messa...

For instance,in the sequence below, 5...
As I know in win32 every program receives say 4GB of virtual memory. Memory manager is responsible for offloading chunks of memory from physical memory to disk. Does it imply that malloc or any other memory allocation API will throw OUT_OF_MEMORY exception only when virtual limit is hit? I mean is it possible for malloc to fail even i...
Hi, I'm interested in how plausible it would be to capture Win32 debug traces system-wide in the way DbgView does. I'm not interested in Kernel messages thankfully so I don't need any help there. This needs to be in C# but I'm happy with unmanaged/unsafe if necessary. Is there any global hook I can get or am I setting off down a diff...
