Question

I remember in VB6 i was able to get the handle of a form of a software that’s currently running, and change it from outside with some API functions.
Is it possible to do with c#? how? The problem is that this software is in a different language. I want to change some of it to English.

Answer 1

Try to use FindWindow and SetWindowText from Win32 API:

FindWindow c# signature:

[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

SetWindowText c# signature:

[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern bool SetWindowText(IntPtr hwnd, String lpString);

and a sample cod:

SetWindowText(Process.GetCurrentProcess().MainWindowHandle, "Hello W");
