I'm using a corporate workstation, and my IT department keeps using programs to restart my PC without my permission. I've asked them to stop, but they don't how how - typical. Anyway, I figured there must be a way of preventing (malicious?) programs like these from restarting my PC... So how about preventing ExitWindows or ExitWindowsEx...
I have been using emacsw32 for a year or so, and I never even realized that meta+r is supposed to be interactive and show hits right away! This works in the unpatched emacsw32 client (which is also much newer, btw). Wondering if anyone knows why this is? Is it the patching breaking it or is it the older emacs? Its not very old though, s...

Using C++ in VS2008, I'm at the beginnings of a DirectX program which can so far display a token image and flip between fullscreen and windowed mode with no problems. It has a menu bar, which is invisible as expected in fullscreen mode. The ALT key could still activate this menu in fullscreen, but it was very clumsy since its items wer...
No, this is not a send me teh codez request. I am writing a small utility for my own amusement.

I am assuming I'll need to PInvoke for...
Hi, I’m trying to use the SendMessage function of a hotkey utility (or NirCMD, etc.) to get a hidden window to pop up. I can for example get windows to close by sending 0x0010 (WM_CLOSE), but when I try sending 0x0018 (WM_SHOWWINDOW) with a wParam of 1 and an lParam of 0, nothing happens. I’ve looked around, and the few places where so...
I noticed that the message WM_NCHitTest isn't sent to a form when the cursor is inside the caption bar (not on the border). I tried to intercept it using either procedure WMNCHitTest(var Message: TWMNCHitTest); message WM_NCHITTEST; or procedure WndProc(var Message: TMessage); override; According to MSDN I was expecting to receive...

For a requirement to generate per-PC license keys, I need some code which will return a stable and (near) unique key on any PC. It doesn't have to be guaranteed unique, but close. It does need to be reasonably stable though, so that a given PC always generates the same result unless the hardware is substantially changed. This is for a W...

Since, there is guarantee that LONG is 32 bit on any Windows, it's probably safe just to pass (long*) some_var. However, it seems to me quite ugly and I c...
