case WM_COMMAND:
           switch (LOWORD (wParam))
           {
               case IDC_PLAY:
                   static char textmessage[256];
                   SendMessage((HWND)lParam,WM_GETTEXT,(WPARAM)256,(LPARAM)textmessage);
                   MessageBox(NULL,textmessage,NULL,NULL);
                   if(textmessage=="PLAY")
                   {
                                        SetWindowText((HWND)lParam,"Stop");

                   }

I am not entering in to the if though its "PLAY";
How to compare exactly this. I am new to use such cases for WM_COMMAND and sendMessage

change

from

to

C++

if( strncmp(textmessage, "PLAY", 4) == 0 )

(or use a CString).
