Thread: accessing text from another program

Anyone know how I can make a program that can read text from another program's window?

I'm making the program that needs to read the text, but I didn't make the program it needs to read from and I don't have access to its source code.

Is there some Windows API for doing things like this?

Here's a program I just whipped together that might help you a bit.

Code:

 #include <iostream.h>
 #include <windows.h>
 
 int main()
 {
 	while(1)
 	{
 		POINT mouse;
 		GetCursorPos(&mouse);
 		HWND hwnd=WindowFromPoint(mouse);
 		char text[512];
 		GetWindowText(hwnd,text,511);
 		cout << text << endl;
 		Sleep(1000);
 	}
 	return 0;
 }
