Hi,
I've created an ActiveX control. I would like to have a pop-up context menu for when the user right clicks the mouse. However, my search has been proved fruitless.

I've already created the menu in the resource editor. When I add the WM_CONTEXTMENU it generates the code below.

C++

void CMyActiveXCtrl::OnContextMenu(CWnd* /*pWnd*/, CPoint /*point*/)
{
	// TODO: Add your message handler code here
}

What I would like to know is how do I accomplish this and can anyone point me in the right direction.

BTW: I'm using Visual C 2008.

I did the same thing as explained in Solution 2 but my menu items are disabled. Any ideas why this happens and how to get these enabled?

Solution 1

you'll have to catch the WM_RBUTTONUP event and then use CreatePopupMenu and TrackPopupMenu

Best also to work out where the mouse is in relation to the desktop edges, so your menu doesn't display 'out of screen' [MapWindowPoints(yourHWND,NULL,...)]

TrackPopupMenu

method.

I found the solution.
Since my contol is a shape using CRgn First I have to catch the WM_RBUTTONUP message this ensures that point is in the region. Then have to also handle WM_CONTEXTMENU event. Because if I don't the popup menu can appear in the wrong place on the screen.
With the genrated code

C++

void CMyActiveXCtrl::OnContextMenu(CWnd* /*pWnd*/, CPoint /*point*/)
{
    // TODO: Add your message handler code here
}

I comment out the paramaters giving

C++

void CMyActiveXCtrl::OnContextMenu(CWnd* pWnd, CPoint point)
{
    // TODO: Add your message handler code here
}

Inside the body I inserted the following

C++

myMenu.TrackPopupMenu(MY_ALIGNEMT_FLAGS,point.x, point.y,this);
