GetPrivateProfileInt on network file on freshly booted machine
After intensive searching why certain workstations wouldn't perform a certain action when just being started up in the morning (...) I've discovered that GetPrivateProfileInt just returns the default value and doesn't bother to set GetLastError to something non-zero when the network-subsystem hasn't activated yet (e.g. because the DHCP c...

FlushFileBuffers as good as CloseHandle then CreateFile at saving data to disk?
For a file on disk, is the Win32 function FlushFileBuffers as reliable and certain as closing the file using CloseHandle then re-opening the file using CreateFile?

WH_GETMESSAGE global hook not working
I am trying to set a global GetMessage hook on all threads. This is my DLL: #include <windows.h> __declspec(dllexport) LRESULT CALLBACK GetMsgProc(int nCode, WPARAM wParam, LPARAM lParam) { MessageBeep(0); return CallNextHookEx(NULL, nCode, wParam, lParam); } As you can see, it's not much.

Is registration-free activation possible for EXE (out-of-process) COM servers?
I know that we can use CoLoadLibrary and DllGetClassObject to get the IClassFactory interface and get the COM component interface without registering the DLL.

Ok, let's see if this all makes sense. Today, as I began working on a small project, I ran into an error I can't seem to get over.

Hi there, I'm writing some Perl which takes TV shows recorded on Windows Media Center and moves/renames/deletes them depending on certain criteria.
