>Hi all,
>I'm trying to figure out how to recognise when the left mouse button has been released over a different form than the one where the mouse was pressed. I'm trying to drag from a listbox on one from and drop something on a form in the class designer. Right now it sort of works. When I release over the class being designed, nothing happens until I click on the class. Then my mouseup code runs and adds the object. I think I have tried every combination of drag(), mousemove(), etc. and I can't seem to trap that event over another form until I click on that form. It's possible to do this because the toolbox does it, but I cannot for the life of me figure out how they trap this event. Any ideas? Thanks.

Gary,
Why do you try to track the release of mouse button. Start the drag and catch it with DragDrop.

ie:

*Form1.text1.MouseDown
Lparameters nButton, nShift, nXCoord, nYCoord
If nButton = 1
  nStart = Seconds()
  Do While Mdown() And Seconds()-nStart < 0.4
  Enddo
  If Mdown()
    This.Drag(1)
    oObj = Sys(1270)
    cSCX = Sys(1271,oObj)
    cHierarchy = Sys(1272,oObj)
    MessageBox('Drag ended'+Chr(13)+;
    'FormFile :'+cSCX+Chr(13)+;
    'Hierarchy:'+cHierarchy+Chr(13)+;
    'Object class'+oObj.Baseclass)
  Endif
Endif

*Form2.text1.dragdrop
LPARAMETERS oSource, nXCoord, nYCoord
this.Value = oSource.Value

*Form2.Label1.DragOver
LPARAMETERS oSource, nXCoord, nYCoord, nState
oSource.drag(0) && Cancel the drag
