ListBox Drag and Drop

[Eric]

I'm trying to implement Drag and Drop with objects in list boxes and I'm not having any success. I can drag and drop strings, but when I try to change the code to drag an object it allows me to pick up the object and the mouse changes when I get over a place that will accept the drop but when I let go of the mouse button it sits there for about 3 seconds then the mouse turns to the normal pointer and the object isn't listed in the drop listBox but is also gone from the place I dragged it from. Following is my code unsuccessfull code

private void box1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e

if(box1.Items.Count==0
return
int index = box1.IndexFromPoint(e.X,e.Y)
SchedStudent s = (SchedStudent)box1.Items[index]

DragDropEffects dde1=DoDragDrop(s, DragDropEffects.All)
if(dde1 == DragDropEffects.All
{
box1.Items.RemoveAt(box1.IndexFromPoint(e.X,e.Y));
}
private void box2_DragDrop(object sender, System.Windows.Forms.DragEventArgs e

SchedStudent str= (SchedStudent)e.Data
box2.Items.Add("test")
private void box2_DragOver(object sender, System.Windows.Forms.DragEventArgs e

e.Effect = DragDropEffects.All
