How to perform something after dialog is initialized and displayed.

[TPN]

Hi all, I want to perform file copy operations and display a progress-bar after my dialog has just been initialized and displayed with out any user action such as clicking on a button... However I cannot put that codes in the OnInitDialog() virtual function of that dialog. If I do that, the dialog will appear after all operations are ended. Please help to show me how to do that. Thanks in advance.

Hi. U r requirement is to display this progress only when user starts the file transfer operation say by clicking on any button. You can take the following approach... 1. Add the Progress at the time of Layouting your dialog box. 2. Keep that progress bar invisible. 3. When user starts file transfer process; make that progress bar visible. U can use CWnd::ShowWindow(TRUE/FALSE) to show and hide perticular control.

One easy way would be to set a timer (SetTimer) in your OnInitDialog and in the handler for the timer, kill the timer and start your copy process. You could probably get away with just a 10-20 millisecond setting for the timer. Hope that helps.

The way I've always done this is to post a user-defined message right before OnInitDialog() returns. In your handler for that message, do your processing.

Thank you, Sameer_Thakur. I just only want to start the file transfer operation automatically after the dialog box is displayed (exactly after OnInitDialog() called) without clicking any button, without any user action. Thank you.

Thank you DavidCrow. I think your sugesstion is better than using a timer, because using a timer looks manually and not reliable. But I don't think that Windows doesn't support this situation. Once again, thank you.
