Hide Controls When Setting Properties To Avoid Multiple Repaints
Every repaint is expensive. The fewer repaints Visual Basic must perform, the faster your application will appear. One way to reduce the number of repaints is to make controls invisible while you are manipulating them. For example, suppose you want to resize several list boxes In The Resize Event for the Form:
Sub form_resize ()
DIM I as integer, Sheight AS Integer
Sheight = scaleheight / 4
For i = 0 TO 3
LSTDISPLAY (i) .MOVE 0, i * sheight, _
Scalewidth, Sheight
NEXT
End Sub
This creates four separate repaints, one for each list box. You can reduce the number of repaints by placing all the list boxes within a picture box, and hiding the picture box before you move and size the list boxes. Then, when you make the Picture Box Visible Again, All of Of
The List Boxes Are Painted In A Single Pass:
When moving pictures in VB, the speed is slow, and when the picture is large, you can use the following method:
Sub form_resize ()
DIM I as integer, Sheight AS Integer
Piccontainer.visible = false
Piccontainer.move 0, 0, Scalewidth, ScaleHeight
Sheight = scaleheight / 4
For i = 0 TO 3
LSTDISPLAY (i) .MOVE 0, i * sheight, _
Scalewidth, Sheight
NEXT
Piccontainer.visible = true
End Sub
