>This should work fine. Try dropping an instance of CPageFrame on the sample Project Manager's "Projects" form. It instantiates without a hitch!

Your right, it does work fine there... plus I know I did this in an older version. But what I'm seeing is really strange. Here's the details:

Version 4.2, we have an application specific subclass of cBizObjForm that doesn't have any special functionality built into it at this point. I subclassed from that for my form & added cPageframe with 3 pages. Each of those 3 pages contains another cPageframe instance. The inner pageframes each contain a BizObj sent to back, an aGridList instance (cCgridList inside of cContainer), and a commandbutton eventualy. When I run the app and DoForm() gets to the CreateObject call for my form class it hits an error with tcSys16 = error 2005 and the message pointing to ccontrl.vct.

Now here's the odd part - if I trigger the offending form from toolbar, the mouse pointer turns into an hourglass and just sits there. In the debugger I can see the error event running but it doesn't get logged to the event log and the app ends up back at Read Events. If I trigger the form from the menu, I get a blank program error dialog but it still doesnt get logged. If I start stripping the controls off the form, as soon as I take off the inner pageframes it instantiates just fine. I even tried it with just the outer pageframe containing my aGridList and that works fine too. As soon as I throw that inner pageframe (with or without the aGridList)into the mix it chokes.

I tried to make the outer pageframe only based off of VFP base class and the form will run until I edit/save it in the class designer. Then on the next run I get an error pointing to ccontrls.vct again that says something to the effect of "invalid container for this type of control". If I leave the outer pageframe based on cPageframe and the inner pageframes based off of VFP base class I get the same problem as using cPageframe for both.

I rebuilt/recompiled the entire project, tried using a direct subclass of cBizObjForm, tried getting a fresh version of the ..\MMortals\Libs directory, and tried running it on another workstation - no difference. At which point < g > I copped an attitude and just used VFP base class with the additional error method parameters used by the framework added to each instance. This works but I would much rather be able to use cPageFrame now that I seen it work in the ProjMgr app. Any suggestions?
