i am trying to insert text into notepad.
CWnd *myWnd = FindWindow(_T("Notepad"), _T("Untitled - Notepad"));
if(myWnd)
{
::PostMessage(myWnd->GetSafeHwnd(),WM_CHAR,(BYTE)'a',0x000e0001);
//::PostMessage(myWnd->GetSafeHwnd(),WM_DESTROY,0,0);
}if i enable the second line, notepad is quitting. how to insert a character? it is not working.

- to reduce (an object) to useless fragments, a useless form, or remains, as by rending, burning, or dissolving; injure beyond repair or renewal; demolish; ruin; annihilate.
You're getting the main window for notepad.exe - so it shouldn't come as a great shock that if you send a DESTROY! message, it closes. What did you expect? Even if you actually had the text area for notepad, why on earth would you think WM_DESTROY would help you put a character there? I hope I'm missing out on something in your question that you didn't write down. Your idea of sending a WM_CHAR isn't bad - but you're sending it to the main window for the application. If I use Spy++ on notepad, there are two child windows - a big edit one, and a status bar window. You could get the child window, and try sending the WM_CHAR to that. But that is implementation dependent. For all I know, notepad.exe under Vista is built completely differently. Maybe it uses a richedit window, rather than an edit one? Or Notepad under windows 2000 didn't have subwindows, it just worked as you expected. I would have a look at WM_PASTE message. It's likely the notepad's parent window would pass it on to the child edit window to handle, and that would paste the contents of the clipboard into notepad. It is harder to set up some text on the clipboard - but there are samples on codeproject - and it would allow you to do more than one letter at a time. I hope that helps, Iain.

Uhmmm, are you sure the notepad is aware of such a message? :-D

[my articles]I was wondering when you'd spot that... I'm going to have to change it now! Iain.

WM_DESTROY is a notification message from the system. Sending it to a window that actually isn't being destroyed isn't going to do anything except possibly leave the target application in an unstable state. What are you expecting sending that message to do? Mark
