Need to force a repaint somehow

[Algar]

I am manualy drawing 2 graphs on a picturebox. I put the drawing code in a routine and call it front the _Paint() event.

 

The problem is:

When the form is first loaded its invisible, and when I move the form from halfway off the screen, it won't repaint fully.

 

So basicaly I need a way to make this picturebox repaint no matter what happens

 

Here is the relavent code:

 

======== Form Load =========

Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
                               Call MakeGraph()
	Me.SetStyle(ControlStyles.ResizeRedraw, True)
	Me.SetStyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.UserPaint Or ControlStyles.DoubleBuffer, True)
End Sub

======== Control Paint =========

Private Sub picGraph_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles picGraph.Paint
	Call MakeGraph()
End Sub

 

Also to note, it works with other controls, just doesn't seem to want to go with picturebox

Im not excatly sure what you need but since you said you need to force repaint try this:

PictureBox1.Invalidate()

This will make the pic box repaint when you call this. You could call this in your form's move event.

Ok, thanks a lot, works great !

 

I had already figured out that regraphing on the move event worked, but your way is much less resource intensive
