another question on drawing in pic box

[gfreeman1]

i need some help. What i would like to do is create a drawing tool just like the straight line tool in paint. I have the code to draw the line and erase it everytime the mouse moves, and when the button is released the line is erased. Here is the code i have:

Option Explicit
Public A As Integer, B As Integer

Private Sub picDraw_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
A = X
B = Y
End Sub

Private Sub picDraw_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
picDraw.Cls
If Button = 1 Then
picDraw.Line (X, Y)-(A, B), RGB(255, 0, 0)
End If
End Sub

can someone tell me how to keep from erasing the line when the button is released?
i know it probably has something to do with the MouseUp function

try putting it in the mouse Click event instead of mouse down event

Private Sub picDraw_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) 
'picDraw.Cls <-REMOVE
If Button = 1 Then 
picDraw.Line (X, Y)-(A, B), RGB(255, 0, 0) 
End If 
End Sub
