Im using MFC to make dailog based program. I have one button that will change my start button text to "TEST" after click. my program crash after I clicked on the button here is the code for the button. void CStart_Button_ChangerDlg::OnText() { HWND starthandle; CWnd StartButton; CWnd* Window = CWnd::FindWindow("Shell_TrayWnd",""); starthandle = FindWindowEx(NULL,NULL,"Button",""); StartButton.m_hWnd=starthandle; StartButton.SetWindowText("TEST"); StartButton.SendMessage(WM_SETTEXT,0,0); //SendMessage (StartButton, WM_SETTEXT, 0); }

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...
