Ajay Kalr #2 / 6	Toolbar at runtime You can do it like this: 1. CToolBarCtrl& tb = m_wndToolBar.GetToolBarCtrl(); tb.SetImageList(...); OR 2. You could also call CToolBar::SetBitmap() to set bitmap. -- Ajay Kalra Quote: >Hello, >I need to create a toolbar with a bitmap specified at run time. >How would I do that? >Thanks, >Svetlana

Ed Fult #3 / 6	Toolbar at runtime How would I go about making toolbar buttons unavailable dynamically? when I startup all of the toolbar buttons are available by default. I want to make them available/unavailable at appropriate times. I can't seem to find this in the MSDN so I must just be looking in the wrong place. I created the toolbar which contains many buttons.

Eugene Kai #4 / 6	Toolbar at runtime Hello, If you only want to enable/disable the toolbar buttons, you should use the standard UPDATE_COMMAND_UI mechanism. If you want to dynamically change the toolbar itself (to have additional buttons...) you can use the following function to switch between 2 toolbars: void EkSwitchBars( CFrameWnd* pFrame, CControlBar* pBar1, CControlBar* pBar2, BOOL bShowBar2, BOOL bDelay /* = TRUE / ) { ASSERT_VALID( pFrame ); ASSERT_VALID( pBar1 ); ASSERT_VALID( pBar2 ); // 1 - Compute "From" and "To" bars CControlBar pBarFrom = bShowBar2 ? pBar1 : pBar2; CControlBar* pBarTo = bShowBar2 ? pBar2 : pBar1; BOOL bVisible = EkIsBarVisible( pBarFrom ); // 2 - Exchange "From" and "To" window IDs UINT nIDFrom = ::GetWindowLong( pBarFrom->GetSafeHwnd(), GWL_ID ); UINT nIDTo = ::GetWindowLong( pBarTo->GetSafeHwnd(), GWL_ID ); ::SetWindowLong( pBarFrom->GetSafeHwnd(), GWL_ID, nIDTo ); ::SetWindowLong( pBarTo->GetSafeHwnd(), GWL_ID, nIDFrom ); // 3 - Hide "From" bar, show "To" bar if "From" bar was visible pFrame->ShowControlBar( pBarFrom, FALSE, bDelay ); pFrame->ShowControlBar( pBarTo, bVisible, bDelay ); Quote: } The above code can easily be generalized to switch between more than 2 toolbars. You will find additional details in FAQ 6.8 of "The MFC Answer Book": How do I dynamically switch between different toolbars?

Eugene Kai #6 / 6	Toolbar at runtime Hello, If you want to enable/disable toolbar buttons, you should use the standard UPDATE_COMMAND_UI mechanism and write update handlers. If you want to dynamically switch between different toolbars (with additional buttons, graphics, etc.) you can use the following function excerpted from my own "MFC Answer Book": void EkSwitchBars( CFrameWnd* pFrame, CControlBar* pBar1, CControlBar* pBar2, BOOL bShowBar2, BOOL bDelay /* = TRUE / ) { ASSERT_VALID( pFrame ); ASSERT_VALID( pBar1 ); ASSERT_VALID( pBar2 ); // 1 - Compute "From" and "To" bars CControlBar pBarFrom = bShowBar2 ? pBar1 : pBar2; CControlBar* pBarTo = bShowBar2 ? pBar2 : pBar1; BOOL bVisible = EkIsBarVisible( pBarFrom ); // 2 - Exchange "From" and "To" window IDs UINT nIDFrom = ::GetWindowLong( pBarFrom->GetSafeHwnd(), GWL_ID ); UINT nIDTo = ::GetWindowLong( pBarTo->GetSafeHwnd(), GWL_ID ); ::SetWindowLong( pBarFrom->GetSafeHwnd(), GWL_ID, nIDTo ); ::SetWindowLong( pBarTo->GetSafeHwnd(), GWL_ID, nIDFrom ); // 3 - Hide "From" bar, show "To" bar if "From" bar was visible pFrame->ShowControlBar( pBarFrom, FALSE, bDelay ); pFrame->ShowControlBar( pBarTo, bVisible, bDelay ); Quote: } You will find additional details in FAQ 6.8 of "The MFC Answer Book": How do I dynamically switch between toolbars?
