    Object reference not set to an instance of an object with hs.GETUrl VB Script

    I am running the following script and I get the following error. Any thoughts?

    Sub main()
    Dim startint
    Dim Endint
    Dim Strdata as string


    Strdata = hs.GetURL("http://lite.cnn.io", "/en" , true, 80)

    End Sub

    VB.Net script exception(0), re-starting: Object reference not set to an instance of an object

    Your startint and Endint variables are null. Initialise the variable as an integer and assign a value. Or just remove them from your dimension section of code

        Change your script to:

        Code:
        Sub Main(parms As Object)
          Dim Strdata As String
          Strdata = hs.GetURL("http://lite.cnn.io", "/en" , true, 80)
        End Sub
        HS tries to pass a input parameter to Main, but your Main did not allow it.

            Well, your script will fail without that declare.

            How are you evoking this script? Will the script work if you replace the GetUrl call with:
            Code:
            hs.WriteLog("Testing", "Testing")
            The script error processing can be a little obtuse sometimes. Can we see the entire error message (which should be in the system log, where you should see the Testing message as well)?

                Are you by chance calling the script from an event? If so when it asks for sub to call are you using Main? If so I would remove the main. I have had problems with this before.

                  That throws a namespace error:

                    Can you post your whole script with the forums script tags around it?

                      hs.writelog ("test", "test")

                        You are missing main after the sub. I was talking about the call from event to remove the main.

                              If you are getting the same error without the GetUrl statement (in other words, just the writelog statement), then it is something else.

                              Is it possible that some other script is trying to run, or is running, at the same time? The error may be unrelated directly with your script.

                              Hate to ask this, but if you can dump out the actual log with some lines before and after the script, maybe we can spot something.

                              Otherwise, I am not seeing it yet.

                              (This assumes you have made the corrections mentioned above, including adding back "Main" to your subroutine declaration.)
