Can I have clipboard shortcut keyevents sent to my cvi MainCallback Funciton?

Hello,

After reading the post Ctrl - Alt Keypress, I wrote a program as below:

int panelHandle = 0;

WNDPROC currentWndProc = 0;

int main (int argc, char *argv[])
{
	............
	panelHandle = LoadPanel (0, "test.uir", test);
	InstallMainCallback (EventFunc, NULL, 0);
	InstallParentWndProc ();
	............
}

int CVICALLBACK EventFunc (int panelOrMenuBarHandle, int controlOrMenuItemID, int event, void *callbackData, int eventData1, int eventData2)
{
	............
	if (event == EVENT_KEYPRESS)
	{ 
		...........//codes trying to catch Ctrl+C/V keyevents and do sth.
	}
	............
}

LRESULT CALLBACK ChainedParentWndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	switch (message)
	{
		case WM_KEYDOWN:
			if ((GetKeyState (VK_CONTROL) & 0x8000) && (wParam == 'C'))
			{
				break;//can catch Ctrl+C here
			}
			else if ((GetKeyState (VK_CONTROL) & 0x8000) && (wParam == 'V'))
			{
				break;//can catch Ctrl+V here
			}
		default:
			return (CallWindowProc (currentWndProc, hwnd, message, wParam, lParam));
	}
	retrun FALSE;//or DefWindowProc//or CallWindowProc//doesn't make sense
} 

int InstallParentWndProc ()
{
	intptr_t PanelWindowHandle;
	............
	GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, &PanelWindowHandle);
	currentWndProc = (WNDPROC)GetWindowLongPtr ((HWND)PanelWindowHandle, GWLP_WNDPROC);
	SetWindowLongPtr ((HWND)PanelWindowHandle, GWLP_WNDPROC, (LONG_PTR)ChainedParentWndProc);
	............
}
