Typographical error in the code (not that it is causing a problem). This line
mDrawingAreaMatrix[X] = NEW DrawingArea(Panel1) AS "Card" & CInt(X) CInt(X) is redundant and not at all what I was thinking about when I typed that line. It should more properly read; mDrawingAreaMatrix[X] = NEW DrawingArea(Panel1) AS "Card" & CStr(X) I'm beginning to think that what I am trying to accomplish is not possible. How can a Draw event that is not in the compile-time source be accessed during run-time?
