Is there any way to retrieve this data through the win32API? I've tried GetWindowInfo() and stuff but I think I'm not heading in the right direction.. thanks edit: I'm iterating with Enu...
Usually, when a user holds the mouse pressed over a button, moves the mouse away from the window, and then releases it, the button can tell that the mouse has been released even though the release has actually occured outside the window. When I inspect mouse clicks in my window, how can I imitate the same behavior? When a mouse button ...

I can only imagine I'm not searching correctly; this seems like an obvious question to be asked here. My apologies if this is a duplicate. I'm writing a Perl program that will take a filename as a command-line argument. I need to convert the filename (or the filename with a relative path attached) to an absolute path (specifically to wo...
I need to register a window class, and right after that set some data in it's extra memory section (the one cbClsExtra refers to) before any window of the class is being created. The problem is that SetClassLong expects a HWND in order to identify the class, instead of the class's name or atom. What's the way to acheive this? ...
Question: Are there Windows API calls (perhaps NTFS only) which allows one to split a very large file into many others without actually copying any data (in other words, specify the logical breakpoints between joined files, with file names and sizes)? Examples: SetFileValidData, NtSetInformationFile Scenario: I need to programatically...
What is the best way for detecting whether a network interface is a loopback adapter? The windows API's GetAdaptersInfo and GetAdaptersAddresses state in the documentation that they will return whether an interface is a loopback through the Type (MIB_IF_TYPE_LOOPBACK) but neither of these do for the Microsoft Loopback Adapter at least, ...

I'm trying to create a function that takes the name of a directory (C:\foo\bar, or ..\foo\bar\..\baz, or \\someserver\foo\bar), and creates directories as necessary so that the whole path is created. I am attempting a pretty naive implementation of this myself and it seems to be a string processing nightmare. There is / vs \, there is ...
