Many many moons ago I did some drag and drop code, but I have forgotten completely and it's no longer in my possession anyway. I want to drag names amongst a screen full of listboxes: https://www.screencast.com/t/6M8XxvSFV
I know I need to code in the OLEDragDrop event and native VFP Help sucks, not really showing me anything.
I was thinking the oDataObject was the listbox where the drag started but no. I tried to SET STEP ON but VFP says "CANCEL or SUSPEND is not allowed."
LPARAMETERS oDataObject, nEffect, nButton, nShift, nXCoord, nYCoord LOCAL loLB as ListBox loLB = oDataObject wait window loLB.ListCount && this fails
SET STEP ON && this doesn't work either
I have the properties set correctly to allow me to drag from one list to another but now I'm stuck. Going to search the archives next but throwing this out there in the meantime. Was hoping to have drag/drop implemented by the time I had a ZOOM call with my fellow hockey captains to set the teams tonight!
