The easiest way is to edit the dialog with the resource editor

Using the resource editor (the little tree tab between the classes and the files tab) select the dialog to edit it.  Place the cursor on the dialog and right click once then select properties.  On the Properties dialog ,use the Styles tab, then uncheck the Title box.  You will see the title bar disappear instantly.  Recompile and your on your way.  Let me know if you need more help...

Use WS_MODALFRAME and WS_DLGFRAME (no caption) in ModifyStyle function.
