Refreshing Object on Form

You can cause the area of the control to call the paint event by doing the following after you have the width.

NameOfControl.Invalidate()

'Also call update after invalidate to syncronize it.

NameOfControl.Invalidate()
NameOfControl.Update()

...or just call the controls Refresh() method:

    NameOfControl.Refresh()

ok how would I refresh an object on frmMain from a different form?

You need a reference to frmMain from your secondary form:

Public Class frmMain
    Inherits ...

    Public Sub Button1_Click(...) Handles Button1.Click
        Dim f2 As New Form2
        f2.fMain = Me
        f2.Show()
    End Sub

End Class


Public Class Form2
    Inherits ...

    Public fMain As frmMain

    Private Sub foo()
        If Not (fMain Is Nothing) Then
            fMain.Label1.Text = "Something..."
            fMain.Label1.Refresh()
        End If
    End Sub

End Class

Below code does not work... gives me an invalid instance code... help?        

        Dim mainForm As frmMain

        overallRun = overallRun + EventsFinished
        overallWidth = Convert.ToInt32((overallRun / overallCount) * 436)
        mainForm.loadbarOverall.Width = overallWidth
        mainForm.loadbarOverall.Invalidate()
        mainForm.loadbarOverall.Refresh()
