When I resize (Enlarge) the form while the progress bar is running the
rectangle drawing is not going to the end of the rectangle?
I got a form with one button, one statusbar with three statusbarpanel
Here is the code for help
What is wrong there?
#Region "ProgressBar"
Public Structure progresspanel
Dim x As Integer
Dim y As Integer
Dim Width As Integer
Dim Height As Integer
End Structure
Dim pb As Drawing.Drawing2D.LinearGradientBrush
Dim myProgressPanel As progresspanel
Dim g As Graphics
Dim rect As Rectangle
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim t As New Threading.Thread(AddressOf progress)
t.Start()
End Sub
Private Sub StatusBar1_DrawItem(ByVal sender As Object, ByVal sbdevent As
System.Windows.Forms.StatusBarDrawItemEventArgs) Handles StatusBar1.DrawItem
myProgressPanel.x = sbdevent.Bounds.X
myProgressPanel.y = sbdevent.Bounds.Y
myProgressPanel.Width = sbdevent.Bounds.Width
myProgressPanel.Height = sbdevent.Bounds.Height
End Sub
Private Sub StatusBar1_Resize(ByVal sender As Object, ByVal e As
System.EventArgs) Handles StatusBar1.Resize
StatusBar1.Invalidate(rect)
End Sub
Sub progress()
Dim i, j, w As Integer
j = 10000
g = Me.StatusBar1.CreateGraphics
For i = 0 To j
w = CInt((myProgressPanel.Width / j) * i)
If w = 0 Then w = 1
rect = New Rectangle(myProgressPanel.x, myProgressPanel.y, w,
myProgressPanel.Height)
pb = New Drawing.Drawing2D.LinearGradientBrush(rect, Color.AntiqueWhite,
Color.LightBlue, Drawing.Drawing2D.LinearGradientMode.Vertical)
g.FillRectangle(pb, rect)
g.DrawString(w.ToString, New Font("Arial", 10, FontStyle.Regular,
GraphicsUnit.Point), New SolidBrush(Color.Red), myProgressPanel.x,
myProgressPanel.y)
Me.StatusBar1.Panels(0).Text = w.ToString
Next
Me.StatusBar1.Panels(0).Text = "0"
g.Flush()
End Sub
#End Region

I tried your code but I can not reproduce the problem. I can resize the form
(resizing the docked statusbar (resizing the panel)) during painting the
panel in the other thread and the panel is always filled completely.

To rreproduce the error that I got:
1) launch the application (should not be maximized) - (if launch full screen
no problem)
2) press the button to start the progress bar
3) while the progress bar is incrementing, grab the right side of the form
to strech widely the form then release the mouse before the progressbar
stop. The progress bar counter should still increment (indicating the width
of the statusbarpanel) but the drawing is not going anyfurther then his
original maximum width instead of going to the end of the panel.
Thank you for your help if you find anything

Hi,
I know this is not of help to you but I'd like to ask you help me make a
progress bar. I need to make a pop up progress bar (on a form) that will
show progress of a file download.
Can you help me with that.
Thanks,

That's what I've already done, but it was not reproducable. Now I did it
again, and, you are right, I can reproduce it. Well, when the graphics
object is created the width is smaller. If you resize the panel in the
meantime, you probably have to destroy the graphics object and create a
new one.

Thank you, I think it work with this approach
Private Sub StatusBar1_Resize(ByVal sender As Object, ByVal e As
System.EventArgs) Handles StatusBar1.Resize
g = Nothing
StatusBar1.Invalidate(rect)
g = Me.StatusBar1.CreateGraphics
End Sub

Sorry Armin,
I don't get it. I don't use status bar and I don't use a graphic object.
Can you explain to me little bit more how to use what you just posted.
I appreciate your help

I only added "g.dispose" to Nicolas' code because the Dispose method of
disposable objects should be called before setting the reference to Nothing.

Actually this is better with a little check before isNothing() otherwise it
doesn't "g" at this point to dispose it. the resize event is call event
before I got it setup..
Private Sub StatusBar1_Resize(ByVal sender As Object, ByVal e As
System.EventArgs) Handles StatusBar1.Resize
If Not IsNothing(g) Then
g.Dispose()
g = Nothing
StatusBar1.Invalidate(rect)
g = Me.StatusBar1.CreateGraphics
End If
End Sub
