Hi,
I am using Modeless dialog in a CAD API program, launching it, it closes immediatly after it is created.
I am using this two lines to create the dialog.
MyDialog dlg;
dlg.Create(IDD_DIALOG_SA,0);
dlg.ShowWindow(SW_SHOW);
It just flickers in the sceen, If I show the window, it stays no time. It doesnot call any message functions. Any one knows the reason please suggest resolution.
Thanks in advance.
Joseph
You need to run the message loop (RunModalLoop). It will block until the function closes, but it will not force it to be modal.

Is sounds like the dialog variable is going out of scope right after the showwindow, meaning the function where the dialog is created ends, killing your dialog variable, therefore no dialog.
You will need to have a variable for the dialog that will persist longer than the function it is created in.
Regardless, you will still need to pump messages, which you do with RunModalLoop, and it will block, so there is no problem with running out of scope.
Thanks Dave. That worked. I have not used pointer to create dlg, used as local variable
Thanks for all the replies.
