	Hi, I have created MFC SDI App with view derived from CFormView which hosts FlowChart. It works fine including flowchart item removing by pressing Del key. But when I creates MFC ActiveX with SDI interface which hosts FlowChart in its formview, revoming items by pressing Del key doesn't works. Please could you help me to resolve this issue? Thanks

	Hi, That means that the flowchart does not get a WM_KEYDOWN message when Del is pressed. Try that with the fHandleDelInTranslAcc bit in the KeyboardFlags property set to TRUE - then the FlowChart will handle Del if it is passed to it through the PreTranslateAccellerator COM API function. I hope that helps, Stoyan

	I have a look at flowchart's window messages by using Microsoft Spy++. The spy logs that flowchart window (class name FCX_PRO) receives WM_KEYDOWN/WM_KEYUP with VK_DELETE when I press Del key on flowchart. What could this mean? Is it OK? Thanks

	The message might be intercepted by a hook function in the parent control, or maybe ATL reflects the message to the parent. Then if the parent window handles that key, it won't reach the flowchartx message handler. I believe the first thing happens - MFC forms hook into their child controls' message queues and intercept keys such as tab, del, the arrow keys... Have you tried setting that bit in KeyboardFlags?

	Yes, I have set KeyboardFlags to FALSE. Now items can be removed from flowchart by pressing Del key. Thanks
