Hello,

I try to follow SDI_DynamicBars example but possible missed something. I created non persistant empty dynamic bar and is can be displayed as floating, dockable. It can be hided and viewed. But when I try to set it to Tabbed state I receive Assertion failure in CExtDynamicControlBar::BarStateSet function:

        if( OnQueryChildHWND() == NULL )
        {
            ASSERT( FALSE );...

Thank you in advance

Please create a child window inside your dynamic control bar. Switching a dynamic control bar into document mode in the SDI application is implemented as follows

1) The control bar hides.

2) The child window changes its parent. Now the parent the tab page container window created as the main SDI view window.

3) In the tab page container, a tab item in the tab is registered for this child window .

4) The dynamic control bar is marked as switched into the document state.

As you can see from the above details, the dynamic control bar cannot be switched into document mode in an SDI application if a child window inside this control bar was not created.

I solved the problem: there was no any dialog attached to the control bar.
