I'm trying to change the default windows minimize effect with a C# winforms app. I have no idea where to start. Maybe I should set some kind of hook or something? I just need to know, when a window likes to be minimized, the minimizing itself is no problem. Anyone having any ideas?? ...

I'm trying to interact with a webcam from Java on Windows (without going through the FMJ or JMF frameworks) by using COM4j. However, I'm unable to find the typelib identifier for Direct Show in order to build the interfaces. The COM4j site recommends using OleView to find the typelib, but I've gone through the list of typelibs there an...
I'm porting some sockets code from Linux to Windows. In Linux, I could use strerror() to convert an errno code into a human-readable string. MSDN documentation shows equivalent strings for each error code returned from WSAGetLastError(), but I don't see anything about how to retrieve those strings. Will strerror() work here too? How ...

I've got some code that worked fine under Delphi 2007 but breaks under D2010. It involves passing in a string, converting it to a PWideChar (specifically, a WideString pointer, not a UnicodeString pointer), doing some processing, and then calling SysFreeString on it. It works fine until a blank string is passed in, then SysFreeString b...
I have a console app in .net that I'm doing some processing of fonts. I'm using Win32APIs for this and one of them requires a device context for loading a font - actually a IntPtr hdc = GetDC(handle of screen element). Obviously, my app doesn't have these handles as it's a console app. Is there a way to get around this? ...

I have a menu that contains submenus. eg: Item1 Item2 Item3 item A Item B Item3 has items under it. At any given time 1, 2, or the items under 3 should be checked. Since I don't have an ID for Item3 I have to use the MF_BYPOSITION indicator when I try to set a check on Item3 to indicate one of its children has a checkmark. Item...
The idea is that an existing project uses timeGetTime() (for windows targets) quite frequently. milliseconds = timeGetTime(); Now, this could be replaced with double tmp = (double) lpPerformanceCount.QuadPart/ lpFrequency.QuadPart; milliseconds = rint(tmp * 1000); with lpPerformanceCount.QuadPart and lpFrequency.QuadPart being...

Hello, I was using a ITK library. When I wrote a sample program using this library, I've got following linker errors. As we can see these all "unresolved" symbols are Windows API functions and these windows API functions were used by ITK library and not my program. Error 1 error LNK2019: unresolved external symbol _SnmpUtilVarBind...
In my application, I have a large structure of many objects and children. I'm designing a set of property sheets that you can open to inspect a specific object (and it's base classes) so you can modify them directly. What's the best strategy for populating these dialogs? The current design is to test the current object on dialog open,...

My message loop doesn't seem to see the WM_VSCROLL message, but it does see the WM_NCLBUTTONDOWN message with the HTVSCROLL value in Msg.wParam. Anybody ...
