A Drag drop question
I have managed the following:
From VC6, I have used Ole's DoDragDrop() method and the system global memory to create a unique ID and drag it to Excel, which then triggers a selectionchange event. In that event I call an add-in macro that does a lot of things, including deleteing the unique id from the cell. For the user, there is sometimes a flash of the unique id before I delete it even though I delete it first thing. Questions: 1 - Is there a better (no flash, more reliable) way to trigger an event in Excel with the drag drop. 2 - Is there a way to trigger a permanent macro (in an add-in) in any instance of excel from outside of excel, using COM or DDE or some other communication method? 3 - Regarding the drag/drop, is there any way during the drag over excel to change work sheets or scroll up/down/left/right programmatically - e.g. like a mouse move event or a isdraggingoveryou event in excel? Thanks in advance. |
