I'm trying to write a MATLAB function to find the position in screen coordinates of an arbitrary window (not just a MATLAB window). The code only needs to work in the current version of MATLAB and on Windows XP. I know I could write a MEX-file or shell out to another program, but I want to do this all with MATLAB code. It should be po...
Hi folks, I am currently working on a C++ programm which calls another C# programm I have code-level access to. However when I call the program using CreateProcess(0, temp2, 0, 0, false, 0, 0, 0, &si, &pi) where temp2 contains the executable including command line parameters the C# program starts but the OnLoad event of the MDIForm (= m...
I'm a Mac user and a Windows user (and once upon a time I used to be an Amiga user). I much prefer the menu-bar-at-the-top-of-the-screen approach that Mac (and Amiga) take (/took), and I'd like to write something for Windows that can provide this functionality (and work with existing applications). I know this is a little ambitious, esp...

I know this involves JNI, but how, exactly, do I do this? Do I need to call javah on Wininet.h? Where...

One such application is Skype, which has a button for switching from a one-window-that-contains-everything mode to a one-window-per-conversation mode and vice versa: I'd like to know how you ca...

Also, can I call CreateNamedPipeW or CreateNamedPipeA and ignore whether unicode is enabled, or do I have to call...

Hi, I just started learning programming for windows in c++. I had this crazy image, that win32 programming is based on calling windows functions and sending parameters to and from them. Like, when you want to create window, you call some win32 function that handles windows GUI and say "Hi, please, create me new window, 100 x 100 px, with...
In windows is it possible through an API to write to the middle of a file without overwriting any data and without having to rewrite everything after that? If it's possible then I believe it will obviously fragment the file; how many times can I do it before it becomes a serious problem? If it's not possible what approach/workaround is...
