Hi, in this example i need a WDK installed, is this right? Because VS 10 don't know a "NtQueryInformationFile" and i found on microsoft.com that i need "ntifs.h" to include for this? After all ntifs.h is on my system but now i can't find "windowsfamiliy.h" :( Best wishes bosfan

You're not trying to update the control inside of PreTranslateMessage are you? The controls get updated from messages sent through the message pump. If you're blocking from inside of PreTranslateMessage, then your code could hang.

If functionality provided by the operating system is not sufficient, you might consider using software revision control for your files or differential backup with your prefered tool. Philippe Mori

"%C3%B6" is a two byte character, perhaps the issue has something to do with character encoding (UTF-8 vs UTF-16)? Edit: I see that 0xF6 (246 decimal) is ASCII character "ö". [Window Detective] - Windows UI spy utility
