I have an app that periodically calls CopyToScreen to grab and save a screenshot. It seems that every time I do this I create a GDI object that I can't seem to dispose. I've boiled it down to a simple form with a timer. The code for the form follows:
Option Strict On
Option Explicit On
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim screenSize As Size = My.Computer.Screen.Bounds.Size
Using bmp As New Bitmap(screenSize.Width, screenSize.Height)
Using g As Graphics = Graphics.FromImage(bmp)
g.CopyFromScreen(0, 0, 0, 0, screenSize)
End Using
End Using
End Sub
End Class
I'm watching GDI counters using Process Explorer which I downloaded from Microsoft. The GDI counter will increment up to 10,000 and stay there. I also see my Private Bytes increase.
As a side note, I tried creating a thread for this and got the same results. It seems like I'm missing something pretty basic here. Any help would be appreciated.
