You can add some method which loop  controls and check if control with pControl->IsTemporary()  == FALSE exists.

 

BOOL HasButtons(CXTPToolBar* pToolBar)
{

  for (int i = 0; i < pToolBar->GetControls()->GetCount(); i++) 
  {

     if (!pToolBar->GetControl(i)->IsTemporary())

        return TRUE;

  }

  return FALSE: 

}

 

I use the following code:

 

  CXTPControl* pControl = pToolBar->GetControls()->FindControl(nCmdID);
  if(pControl == NULL) continue;
  pToolBar->GetControls()->Remove(pControl);

 

If I remove all buttons from a toolbar, I want to remove the toolbar also. So I write:

 

  int nTbBtnCount = pToolBar->GetControls()->GetCount();
  if(nTbBtnCount  == 0)
  {
   pToolBar->GetControls()->ClearOriginalControls();
   GetCommandBars()->Remove(pToolBar);
  }

 

This is supposed to be right. However, I find that when the toolbar is visible(sometimes it is not the only case), the toolbar buttons include "close" and "toolbar options" buttons, which are system buttons. So my question is how I know the toolbar has no my own button.
