[Dev-C++] Process keyboard messages

[Tom C. <tho...@ya...>]

hi there,

i'm trying to write a window program to send keyboard input to notepad,
but notepad won't be able to accept the input. can anyone point to me as
what's wrong with the following piece of code?

#include <windows.h>

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow)
{
    HWND hAppWnd;

    if ((hAppWnd = FindWindow(NULL, "Untitled - Notepad"))!=NULL) {
        MessageBox(NULL, "Send a MSG to NotePad", NULL, MB_OK);
//        SendMessage(hAppWnd, WM_DESTROY, NULL, NULL); // this line works
fine
        SendMessage(hAppWnd, WM_CHAR, 65, NULL); // send a "A" character
    } else {
        MessageBox(NULL, "Can't get notepad handle", NULL, MB_OK );
    }
    return 0;
}

TIA!
please reply to tho...@ya...

apparently, the main Notepad window gets the messages, not the edit window in notepad. i don't know if the main window transfers WM_CHAR messages to its child edit.

Does it make a difference if you try WM_KEYDOWN and WM_KEYUP?
