I need to push two options from menu (two different function), and call the same Dialog, and change to different Caption (Dialog title) due to which function call
Caption Location: http://140.134.4.20/~d8825313/1.GIF
Example
OnCopyFile(){
<... set "Copy" title to dlgOper Dialog ...>
dlgOper.DoModal();
}
OnMoveFile(){
<... set "Move" title to dlgOper Dialog ...>
dlgOper.DoModal();
}
I have tried dlgOper.SetWindowTextA(), dlgOper.SetDlgItemTextA(), and didn't work;

How to change "Caption" of Dialog in run-time

It doesn't work because, before calling DoModal, the dialog window is not yet created (the CDialog-derived object has not yet attached a window).
One solution is to add a public member to your CDialog-derived class (e.g. CString m_strCaption), set its value before calling DoModal, then call SetWindowText in the WM_INITDIALOG message handler (OnInitDialog).
Example:
