If you step through the code what happens in the

For i = 0 To lstHSL.Items.Count() - 1
    dataString = dataString + lstHSL.Items(i)
Next i
 

part? Does the string build up correctly? Did you mean to use '&' instead of '+' in the loop?

[DR00ME]

I have allways thought & is same as + ? ...anyway I tried '&' with the same result... I got same error... have to investigate whats going on...

[PlausiblyDamp]

Is the dataString building up in the loop though? What is the value of lstHSL.Items.Count? Try putting Option Strict On at the top of the source file and fix any errors that get generated.

Also what does lstHSL(i) evaluate to in each itteration of the loop?

ROFL, a good point actually I didn't have anytihng in the listbox :DDDD
