Paste to DialogBar

Hi All,

I've got a combo box in a dialog bar (inserted by the Component
Gallery) attached to my MainFrame window. I can set the focus to the
box's edit window easily, but I can't paste text into it. If a document
(based on RichEditDoc) is open, the text is inserted into the doc. How
can I get the combo box edit window to accept pasted text when it has
the focus?

Thanks,

The problem is that the cut,copy, paste keys are being translated by
your app's accelerator table, and the standard windows controls don't
understand ID_EDIT_CUT, etc.

The easiest way round this I've found is to override
PreTranslateMessage() in your control bar, to ensure these keys get thru
to the relevant control. I define a function which I then call from each
CDialogBar's pretranslate message...as it's sometimes useful in other
places. Code is below.

Mark.


BOOL CMyDialogBar::PreTranslateMessage(MSG* pMsg) 
{
	switch(pMsg->message)
	{
		case WM_KEYDOWN:
			if (PreTranslateClipboardKeys(pMsg))
				return TRUE;
    			break;
		.. any other messages you might need to intercept....
	}
    return CDialogBar::PreTranslateMessage(pMsg);
}


BOOL PreTranslateClipboardKeys(MSG * pMsg)
// If the message is a clipboard key (or one that a control is likely to
want),
// then	avoid want to avoid translate accelerator tables.
{
    if (pMsg->message == WM_KEYDOWN)
    {
		int nVirtKey = pMsg->wParam;
		// intercept Ctrl+X, Ctrl +C, Ctrl+V, Shift+Ins, Ctrl+Ins, Shift+Del
		switch(nVirtKey)
		{
			case 'X':
			case 'C':
			case 'V':
				if (IsControlKeyDown())
					goto _TranslateDispatch;
				break;

			case VK_INSERT:
				if (IsControlKeyDown() || IsShiftKeyDown())
					goto _TranslateDispatch;
				break;

			case VK_DELETE:
				if (IsShiftKeyDown())
					goto _TranslateDispatch;
				break;
		}
	}
	return FALSE;

_TranslateDispatch:
	::TranslateMessage(pMsg);
	::DispatchMessage(pMsg);
	return(TRUE);
}

inline BOOL IsShiftKeyDown()
    { return (GetKeyState(VK_SHIFT) & 0x8000); }; // Returns TRUE if the
Shift key is held down ie top bit set

inline BOOL IsControlKeyDown()
    { return (GetKeyState(VK_CONTROL) & 0x8000); }; // Returns TRUE if
the Control key is held down ie top bit set

See MSJ July 95, C/C++ Q&A for how to construct a dialog bar (or
toolbar) with cut/copy/paste functionality.

     MSJ 1995, July issue  C/C++ column has a solution for this.
     Also there is an article on same issue talking about MFC message and 
     command routing. Excellent!!! Both from Paul DiLascia.
