End "Enter" key press event to a program 1

[WilliamCalm]

Hi, friends:

I want to write a small program that runs at background and simulates a key press event to a running program. To be specific, I need the computer to automaticall press the "enter" key once a minute to the active program window, namely notepad.exe, and in all the process the active window should be notepad.exe. Can anybody tell me how to do that in C, or in VB? Thanks. My OS is Windows 98.

Thanks in advance

Here is some code which will find the first "Notepad" program window, find the view window inside it, and simulate a key press by sending it the same window message that it would have gotten if you really did hit the Enter key:

    HWND notepad = FindWindow ("Notepad", NULL);
    HWND notepadEdit = GetWindow (notepad, GW_CHILD);
    if (notepad && notepadEdit)
    {
        SendMessage (notepadEdit, WM_CHAR, (WPARAM) '\r',
                     (LPARAM) 0x001C0001);
    }
