Hi. I'm having problems with a script that changes the TCP/IP settings of my NICs. The script works as it should on most PCs, but on some it don't.

I tried using Win32's GetPixel() with Ruby and it is really slow even on a Quad Core Intel machine. I think for example, if I get a really small region such as 100 x 10 pixels = 1000 pixels and it can take 30 seconds to complete. Is there a better way such as by getting a region all at once? ...

Hello, I am trying to develop a util (using system-hook) for that works like an expander (user selects some text and presses a hotkey and it is expands). It should work with Visual Studio.

So, I'm using AlphaBlend() to copy a rectangle from one HBITMAP to another. It works, but there is a problem. Whenever I use the FillRect() function, the alpha values in the HBITMAP get slammed out to 0. Everytime. So I have to GetDIBits(), reset the alpha back to 255, and then SetDIBits(), after every call to the Win32 api functions...
How can I get the x,y coordinate of a mouse click, to see if it is over my menu button drawn by directx? Currently, my codebase has the following mouse-related class that doesn't seem to be able to give me this..I'm not sure how this might work. InputMouse::InputMouse() : m_LastX(-1), m_LastY(-1) { m_MouseActionEvent.clear(...
I wrote this utility (exe) which can be called from within this host application. And I'd prefer it that the utility can only be called from the host application. Running it from the outside or a different host should terminate the utility immediately. Is there a way to find out which process launched my utility? Thanks for the repli...

Simple question I think, after I have registered a few system-wide hotkeys with RegisterHotKey() do I need to eventually call UnregisterHotKey() to clean them up, or can I simply exit my application without worrying about it? MSDN doesn't seem to say, that or I misunderstand it, anyways: I realize I should just go ahead and call Unregis...

We have a legacy build infrastructure for nightly builds (implemented in Perl) to compile, link and unit tests our applications/plugins. On Windows, if the unit testing process crashes, this pops up a Modal Dialog which "locks" our build farm. Is there a way (win32 API call, system config, env var, something...) to disable this behavior...
How could I create similar structure to handle Win32 Messages like it is in MFC?
