                SendMessageW(hackedh, WM_SETTEXT, (WPARAM) sizeof(TextBuffer), (LPARAM) TextBuffer);

now when ii try to send chars like that it comes up as ?

also hwndEdit is a rich text box

please help..thanks

Well do you have UNICODE defined? I don't usually use WCHAR, I use TCHAR. In non unicode it evalutes to a char and in unicode, a wide char. Maybe that is what is happening. Also don't explicitly call the Wide versions of functions, the compiler will call the correct version for you. Just use SendMessage.

ah thanks for the reply..i worked it out thou
needed to use GETTEXTEX to read from the rtf box
