I have this great code below that does a screen capture of my winform but found that it fails if the workstation is locked.
<pre class="prettyprint lang-vb Private Sub Btn_Image_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Btn_Image.Click
Me.WindowState = FormWindowState.Normal
Me.TopMost = True
Me.Activate()
Me.Refresh()
Dim bmpScreenshot As Bitmap = New Bitmap(Width, Height, PixelFormat.Format32bppArgb)
Create a graphics object from the bitmap
Dim gfxScreenshot As Graphics = Graphics.FromImage(bmpScreenshot)
Take a screenshot of the entire Form1
gfxScreenshot.CopyFromScreen(Me.Location.X, Me.Location.Y, 0, 0, Me.Size, CopyPixelOperation.SourceCopy)
Save the screenshot
bmpScreenshot.Save("image.jpg", ImageFormat.Jpeg)
End Sub[/code]
I get the below Win32Exception error if the workstation is locked, I need help by fixing the above code or a new method. any help is greatly appreciated.
