With this dll you can get and set the x,y,w,h of another window. Also, this dll is not fool proof and will fail if there are two windows with the same title.

Functions:

mwin_init()
mwin_get_handle("Window Name/Title")
mwin_get_handle_class("Window Name/Title","Window's Class name")
mwin_set_win(handle,x,y,w,h)
mwin_get_winx(handle)
mwin_get_winy(handle)
mwin_get_winw(handle)
mwin_get_winh(handle)

Download:
The download includes the gmk, dll, and exe

Please give credit to cswenson1 and freaked if used.

Enjoy and give feedback!
Thanks,

Pretty good, but you should allow users to specify a class name to narrow the search down.

What is a class name and how would that narrow the search down?

It's the first parameter in FindWindow: http://msdn.microsof...y/ms633499.aspx

Both of the arguments are optional, see this page for more information on classes.

I still dont understand how it works, how does it narrow down a windows title by saying whether its a scroll bar or button or not

Consider this.
You have two windows having the title "Notepad".
One is the "official one" and the other is a Java program written by some one to see how swing works.
Now, someone using this dll will want to set the Java Notepad window to size 100,100.
In the title parameter he puts "Notepad".
When he runs it the official notepad window shrinks to 100,100.

If you provide class based search, it will help to narrow down the search since both windows can have same titles but not the same class names.

If the class name of the java notepad window is "SwingWin32WindowClass" then putting it alongside "Notepad" will shring the Java window to size 100,100, and will leave the real notepad window untouched.

Thanks freaked! I'll try that later when I get on my other computer. But just for the sake of learing, how did you get "SwingWin32WindowClass"? I understand that swing has to do with java, but how would it work if i made a c++ win32 window or a visual basic window called notepad and the real one?

CreateWindowEx

lpCLassName is used when creating windowed applications. Now, I do not know how the RAD (VB, Delphi, etc.) applications handle their window classes, but you don't need the class info, the user needs to know.

If you want to find the class names of other windows, use a tool called Spy++.
It will let you find the Handle, class name, process id, and other stuff for windows.
NB: Every Control is a window.
And as for "SwingWin32WindowClass", I made that up.

Ok, thanks! I downloaded Spy++ and got the class names of like paint and notepad. Anyways, i added another function to allow the user to input the title and the class name if they want. Thanks for your guys help in explaining class names!
