easiest way is following step as I think
1) Add control array of label if number of dots are not fixed.
2) Add two textbox for co-ordinates entry e.g. textX, textY
3) Add in there textchanged event, enter following code
textX.location = New System.Drawing.Point(Val(txtX.Text) , textX.location.Y)
Collapse | Copy Code
textY.location = New System.Drawing.Point(textX.location.X,Val(txtY.Text))
try this and reply.
