wma and wmv files are Advanced Systems Format (ASF) files.

ASF files are covered in the Windows Media Format 11 SDK[^]
There's sample apps in the SDK as well.

If you choose to use DirectShow to play these files there's the DirectShow[^]
SDK (which is now part of the Platform SDK).

If you want to use Windows Media Player there's the Windows Media Player 11 SDK[^]

I hope a message is sent to parent window when user right clicks a button on CToolBar - so I can display a pop up menu associated with the button.

can a button on CToolBar send message with mouse right-clicking?
if not, any idea to modify CToolBar?

thx

A toolbar sends a NM_RCLICK notification through a WM_NOTIFY message when the user right-clicks
on the toolbar. To get the message in your parent window, add a OnNotify() override to the
parent's class, something like:

BOOL CMyWnd::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
	if (wParam == ID_MYTOOLBAR)
	{
		NMMOUSE *pNMMouse = (NMMOUSE *)lParam; 
 
		if (pNMMouse->hdr.code == NM_RCLICK)
		{
			//process right click
 
			return TRUE;
		}
	}
 
	return CWnd::OnNotify(wParam, lParam, pResult);
}

Now that I've had some caffeine, I thought maybe an easier way would be to let MFC do some of the
work Laugh | :laugh:

ON_NOTIFY(NM_RCLICK, ID_MYTOOLBAR, OnToolbarRClick)
... 
void CMyWnd::OnToolbarRClick(NMHDR *pNMHdr, LRESULT *pResult)
{
	NMMOUSE *pNMMouse = (NMMOUSE *)pNMHdr; 
  
	//process right click
  
	*pResult = (LRESULT)TRUE;
}

change CharacterSet property in your C++ projekt settings (VS2005) to "use unicode charset".
If you are not using VS 2005. Add "_UNICODE" and "UNICODE" define to your preprocessor defines.

A LVN_ITEMCHANGED notification is sent to the control's parent.

maybe u change resource ID of the control?
use class wizard to delete member of the CListBox then add it again.

I just guess so.

Make sure you are trying to use the combo box after the base class version of OnInitialUpdate(...) has been called, or your controls may not have been created or attached-to yet.

Peace!
