PictureBox error when Form_Activated is fired

[Mr.No]

Hi

I am getting an error when I minimize and maximize a form where I dynamically load a picture box. Here's the code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim bRet As Boolean
        Dim myimg As Image
        Dim sAppName As String
        Dim sLogo As String
 
        Try
 
            myimg = New Bitmap("C:\Program Files\Common Files\Microsoft Shared\Clipart\cagcat50\BD06675_.WMF")
            picLogo.SizeMode = PictureBoxSizeMode.AutoSize
            picLogo.Image = CType(myimg, Image)
            picLogo.Refresh()
 
        Catch ex1 As Exception
            MessageBox.Show(ex1.ToString())
        Finally
            If Not IsNothing(myimg) Then
                myimg.Dispose()
                myimg = Nothing
            End If
        End Try
 
    End Sub

Before I load the image by clicking the button I can minimize and maximize my form. However, when I load the image in the picturebox, minimize the form and maximize I get the following error popping up:


An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll

Additional information: Invalid parameter used


I get a much longer error message when running the compiled code.

Can anyone help please.

Thanks
