For the new version CExtDynamicBarSite::BarFree(pbar);

Will crash if the the pbar is floating or MDI.

For example: in MDI_DynamicBaras sample add one command to free first bar:

void CMainFrame::OnFree()
{

 CExtDynamicBarSite::BarFree(m_pBarPersistent);

}

The previous version 3.1 will not have this problem.

Thanks.

It seems the answer to the problem is in your message. You are trying to free a persistent bar. This operation is not supported by the design of the dynamic bar site. You did not encounter this problem in the previous code release because persistent control bars were added only in the latest release. Please note that persistent bars are designed as really persistent components which are never destroyed and created again during all the application’s runtime even if the application reloads the control bar’s state.

m_pBarPersistent is just a name, It is dynamiclly created when program start runing.

otherwise you can try this program, it also crash if you float any DynamicBar and try to BarFree it.

void CMainFrame::OnFree()
{
 while (m_arrAllDynamicBars.GetSize()){
  CExtDynamicBarSite::BarFree(m_arrAllDynamicBars[0]);
  m_arrAllDynamicBars.RemoveAt(0);
 }
 //CExtDynamicBarSite::BarFree(m_pBarPersistent);

}
