I didn't know where to begin. And I looked at an example project named DragPics (Examples > Graphics > DragPics), which has scared the hello out of me. Then I searched the board and found a simple example suggested by Tim and serd83. Okay. It's actually that simple. Just put some code under MouseDown and MouseDrag. Now, I've been greatly relieved. I only need to move the knot horizontally, so I only need the left part. My question is how can I set boundaries? Let's say that I want to let a Canvas control to stay between 50 and 200. For the highest part, if I use the following code under MouseDrag, the knot icon will flicker if the user keeps dragging beyond Me.Left>200. Code: If Me.Left>210 Then Me.Left=210 Elseif Else Me.left=Me.left + x - dragX End if This is a totally new territory for me. So my question is probably basic. Muchas gracias for your advice.
