[RESOLVED] OutOfMemory problem?

Hi all! I'm working on a program. It's some sort of a slideshow program. It works fine until one moment, when an OutOfMemory exception appears. Here's the code:

Code:

---

Private Sub TimerCase2_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TimerCase2.Tick
        Dim loop2_1 As Integer = CType(txtLoop2_1.Text, Integer)
        Dim loop2_2 As Integer = CType(txtLoop2_2.Text, Integer)
        intNumberOfLoops += 1
        If intNumberOfLoops > loop2_1 Then
            If Not intNumberOfLoops = 0 Then
                intNumberOfLoops += 1
            End If
            If intNumberOfLoops > loop2_2 Then
                Previewer.PictureBox1.Image = Nothing
            End If
            CurrentImage = CurrentImage + 1
            If CurrentImage > Case2Images2.Count Then
                CurrentImage = 0
            End If
            Previewer.PictureBox1.Image = Image.FromFile(Case2Images2.Item(CurrentImage))
        End If
        CurrentImage = (CurrentImage + 1)
        If CurrentImage > Case2Images1.Count Then
            CurrentImage = 0
        End If
        Previewer.PictureBox1.Image = Image.FromFile(Case2Images1.Item(CurrentImage))
    End Sub

Please help me fix the problem. I'm not familiar with this kind of exceptions.
Thanks in advance!

By the way, I have Windows 7 64bit with 4GB RAM and Intel Core i5.

Anybody???????:confused::confused::confused:

I don't know why you get an OutOfMemory exception. Often when that happens, it isn't because you have an actual shortage of memory. Some parts of the Framework seem to use it simply as a default exception.

All the same, I'm surprised you aren't getting IndexOutOfRange exceptions whenever CurrentImage reaches Case2Images.Count, because Count is 1 more than the maximum index. You need to correct that in two places; maybe it will also correct the OOM error. BB

Does this 'OutOfMemory' exception has anything with the number of 'Public' variables? Because I have many of them and I've read something about that on the Internet, but I'm not sure.

I've never heard of that and it seems unlikely to me. Assuming you've fixed the indexing error, there might be something wrong with one of the images -- maybe too large, or an invalid format. It's often not until you try to show it in the PictureBox that the problem shows up, and it can throw an OOM. What happens if you try with a different bunch of images?

I think I've found the problem. The code that I've posted before is a mess. That may be the problem.

The problem is with my code. It was all messed up. Now I'm cleaning it and I will mark the thread resolved when I finish my program. :)

Ok, I've made the program. The thread is resolved. :D
