error working with exceptions

I dont know why I cant get the stacktrace of the error this way:

I'm doing error handling this way, and the Globals.LogError function below always returns false:

VB Code:

Try
            Dim img As Image = Image.FromFile(imagePath)
            Dim frm As New frmImage(img, imagePath)
            frm.MdiParent = Me
            frm.Show()
            Return frm
        Catch ex As Exception When [b]Globals.LogError(ex)[/b]
        Catch ex As IO.FileNotFoundException
           MessageBox.Show("Error loading image. The following file could not be found: " & ex.FileName, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        [b]Catch ex As Exception[/b]
            MessageBox.Show("Error loading image: " & ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
            ' StackTrace has a value here
        End Try

My problem is that when I check ex.StackTrace in my LogError function, its value is Nothing. But when I check it in the last Catch clause, it has a value. I dont know, is there a reason why this is happening? :confused: :confused: :confused:

ignore the code inside the try catch block...

I don't think ex is assigned to anything until its inside the Catch. That is just a guess really. Can you get the message or other parts of the exception in the LogError method?

well yeah that's the weird part. I can get ex.Message and I can also get the type of the exception. This doesnt make sense! why would the other variables of ex be empty?

I dunno that is wierd.?!
