starthandle = FindWindowEx(Window->GetSafeHwnd(),NULL,"Button",NULL);
::SetWindowText(starthandle, "TEST");However, this will not work as intended as the Start button's text is not drawn in the normal fashion.

The compiler is telling you exactly what the problem is. You are trying to use
CWnd::SetWindowText()which does not take 2 parameters.

I got it working now now Im trying to get working with the user defined edit box. I use control CEdit for the edit box. void CStart_Button_ChangerDlg::OnText() { HWND hWnd; RECT rc; if (hWnd = FindWindowEx(NULL, NULL, "Shell_TrayWnd", NULL)) { ::GetWindowRect(hWnd, &rc); if (hWnd = FindWindowEx(hWnd, NULL, "Button", NULL)) { /* CEdit* text = (CEdit*)GetDlgItem(IDC_EDIT1); CString gettext; text->GetWindowText(gettext); */ CString starttext; m_text.GetWindowText(starttext); ::SendMessage(hWnd, WM_SETTEXT, 0, (LPARAM)(LPTSTR) TEXT(starttext)); } } } compile error: Compiling...
