vb.net upload multiple files script, duplicates all files
Hello All;
I have the following code, of which uploads multiple files at one time.
The issue is this.
I am renaming the files to the current date/time format.ext ......
With this renaming, it is naming the files appropriately, but it is duplicating the files in the upload folder.
Could someone please, take a look at this code, and let me know what is going on with it?
Thank You

You didn't mention WHEN the it is getting duplicated. Are you getting error once in a while?
There is nothing hugely inappropriate with code, that I can spot. All I could see that may be you wish to use HH instead of hh which will give hour in 24H format.

I didn't understand the assignment to GlobalVariables and then taking it back from there. I suggest don't do it unless ABSOLUTELY necessary, I cannot see the reason.
When the file is uploaded to the server, it is duplicated.
All you have to do is make a new "Website" and run this code, and you will see.
As for the GlobalVariable, it is was supposed to be removed.
As it was not needed in this project. Just did not get it out of the example.

Fixed it.
I got it working in this example, I just need to recode my actual project to mimic this example.
But it runs and only uploads one file, and not duplicating files.
I removed the extension and replaced it with the filename of ".mp3"
As that is what I am uploaded to the server.
And all seems to work now.
What I did was went back to the original code from here. aspsnippets
And started over with that code, and then slowly added in the renaming.
When I did the extension, it duplicated the files.
So, I removed it and replaced it with the .mp3 and everything went to working.
I am not really sure what the issue is with the extension being there, but it seemed to cause it to duplicate the files.
So, here is the working CodeBehind.

===========UPDATE=========
In the Event Handler, the end of the line has
>>>> Handles btnUpload.Click
This it what was causing the duplicate.
