When I made a separate class file in code blocks...

I apologize I had the wrong dialog identifier thus the wrong dialog control

The Documentation says DDX_Text is for a edit control and I am getting an assertation

So maybe I have to use GetDlgItem and SetWindowText to set the text of the CTEXT

If you implement the Cancel button in a modeless dialog box, you must override the OnCancel method and call DestroyWindow inside it. Do not call the base-class method, because it calls EndDialog, which will make the dialog box invisible but not destroy it.

No David its a Modeless dialog pressing the Ok button doesn't close the dialog like on a normal modal dialog.

He is probably going to put some other button on screen to exit but its a stock standard modeless dialog.
