Magical Toolbars

Hello,
Env : Win 95, MSVC 4.0, MFC

This is a wierd problem I have encountered. I have an application with =
some toolbars. When I go to and return from "Print Preview" (which is =
handled by MFC) all my toolbars are suddenly visible.=20
Tracking the code I found that in "winfrm.cpp" a function =
"OnSetPreviewMode" is called which displays the first 32 control bars, =
before going into preview mode.
Is there some solution for this problem? Or some workaround?

Thanks in advance.

Pradeep.

     Hi,
     Env : Win 95, MSVC 4.0, MFC
     
     I too have the same problem.I guess there are more legant solutions to 
     it but the way i am currently handeling this is, to show or hide the 
     relavant toolbars in the view's on activate handler. Please let me 
     know about any other workarounds.
     Thanks in advance.
     Ratan.

The first 32 toolbar id's are special in this sense, and this is
documented in a tech note somewhere. The workaround is to use ID's
outside the first 32 for your toolbars/dialog bars.

Text item: 


CMainFrame::OnPrintPreview()
{
        CFrameWnd::OnPrintPreview();

        //
        // Insert code here to disable the tool bars you want disabled
        //
}

Checkout the CPrintPreviewState structure, the member, dwState, is a 
bitmap of which bar on and which bar off. If for some reason, dwState is 
set to 0xffffffff before going in into the OnSetPreviewMode, then all 
first 32 bars will be displayed.

	Rukmar,

 	Use this code to find the next available id for your toolbar
	
	unsigned int nIDToolBar;
	for (nIDToolBar = AFX_IDW_CONTROLBAR_FIRST; nIDToolBar < AFX_IDW_CONTROLBAR_FIRST + 256; nIDToolBar++)
	{
		if ( NULL == this->GetControlBar(nIDToolBar) )	// stop when we don't find a control bar
			break;
	}
	ASSERT(nIDSelector < AFX_IDW_CONTROLBAR_LAST);
