I am trying to paste a bitmap on a button

CButton *dlgButton = (CButton*)GetDlgItem(IDC_START);
      CBitmap key;

Answer : how to paste a bitmap on a button

make the CBitmap key   as memeber variable of your dialog box.
Because you have defined it as local variable thats way its not getting displayed.
