After hours digging into the code i think i found the problem with the deletefile not working (i mean...i am sure i found it and i put a sort of "bandaid" on my version of the code....but i am definitely not sure it won't cause other problems....since the source of the problem is in another part of the code...but i didn't know how to fix it properly).
Here are my discoveries (all these code snippets are in form1.vb).
The main problem is in the Public Sub ClearMainPictureBox() ....this sub gets called a lot of times....but is completely empty so it does nothing at all actually.....and here is the source of the problem i think....in most cases it doesn't give problems, but when it is called in a loop cycle like when @DeleteLocalFile is used, then it stuck the program completely.
Your code is this:
If StringClean.Contains("@DeleteLocalImage") Then
Debug.Print("FoundString = " & FoundString)
If Not mainPictureBox Is Nothing Then
ClearMainPictureBox()
Do
Application.DoEvents()
Loop Until mainPictureBox.Image Is Nothing
End If
As you can see it gets stuck in the loop because ClearMainPictureBox() does nothing as i said earlier....and so it never exit the loop.
I changed it like this:
If StringClean.Contains("@DeleteLocalImage") Then
Debug.Print("FoundString = " & FoundString)
If Not mainPictureBox Is Nothing Then
<b>mainPictureBox.Image = Nothing</b>
Do
Application.DoEvents()
Loop Until mainPictureBox.Image Is Nothing
End If
Now it goes on and cancels the image as expected....everything seems to work fine.
The problem is that, this same loop is called also by other parts of the code (@SlideshowLast for ex....and dont remember how many others...) so, this is clearly a temporary solution to the problem itself because when the other similar loops gets called we're back to the same problem.
I also tried leaving the @DeleteLocalImage part of the code calling ClearMainPictureBox() and the modifying the sub like this:
Public Sub ClearMainPictureBox()
mainPictureBox.Image = Nothing
End Sub
It doesn't work well though....the problem is that everytime it changes a pic, the screen blinks black for a fraction of a second before showing the next pic,which is kinda annoying....so, for now i preferred leaving it with the temporary "bandaid" and using that trick in every part of the code there was the loop....it works but i don't know if it is the right solution :).
I hope these information will help you track the problem and solve it correctly...because i have just started learning vb and this code is a bit too big and messy for me to understand completely :D
