    Unhappy When my modeless dialog has been closed it doesn't open again

    Hi !

    The title bar of my modeless dialog ends with the wellknown square red button I hit to close the dialog.
    Unfortunately, the dialog can't be open again after closing it.
    I guess I should modify or add some code to solve the problem.

    Any suggestion ?

    Thanks a lot for your help.

    Best regards.

    Sorry, but I don't see what you mean. Do you need an e-mail ?

    What he means, is that you have to post some code examples by replying to the messages, not by email.
    Are you using the correct function to terminate the dialog? I think it's called EndDialog() for modal dialogs..

    OK.

    Dialog's name : First , its ID: IDD_FIRST_DIALOG, its Class : CFirst.

    First.h
    Code:
        BOOL bCreate;
    MainFrame.cpp
    Code:
        CFirst oneDlg;
    
        void CMainFrame::OnCurrents()
        {
              if (oneDlg.bCreate)
                        oneDlg.SetFocus();
              else
                    {
                          if (oneDlg.create( IDD_FIRST_DIALOG, this));
                                    oneDlg.bCreate = TRUE;
                    }
        }
    First.cpp
    Code:
        void CFirst::OnOK()
        {
              UpdateData(TRUE);
              if (DestroyWindow())
                        oneDlg.bCreate = FALSE;
        }
    I repeat that when I press the OK button I have no problem to open the dialog again.

    Anyway thanks again for your help.

    try

    Only modless dialogs can be destroyed. Replace the destroywindow with a call to

    CDialog EndDialog()


    also I would replace the flag oneDlg.bCreate with say

    if ( oneDlg.GetSafeHwnd() )
