    No need to mark it closed. It'll just move on and be there for anyone else with a similar issue :)
  2. In Topic: There is already an open datareader error

    Posted 28 Mar 2015

    OK, I honestly didn't look that far down. I haven't dug into your code but is there a way you can move that reader code (the lines I originally told you to remark) down to just before you need to read the information for the memorystream.

    The fill would have finished by then and you shouldn't have an issue with multiple readers open.

    If that doesn't fix it, I'll take the time to read it closer a little later when I have more time.

    That's not the button click code. That's creating buttons. The button click code would be the UserClick2 Sub

    While you're at it, we'll need to see the UserClick sub too.

    When two different methods of input, produce two different outputs to the same user interface, it leads me to believe you have duplicated code in your project to do the same thing. Then from the back of my mind an old song from Sesame Street surfaces and I start humming it.

    Let's see the code for the button
  5. In Topic: There is already an open datareader error

    Posted 28 Mar 2015

    line 7 opens a datareader (although I don't see you doing anything else with it)
    line 13 open a datareader through Fill method on the dataadapter.

    Scanning your code I think you're trying to do the exact same thing two different ways. Since you appear to end up using the dataset, I would remark out any of the code above that (lines 5,6 and 7) as they are setting up for the reader.
