Invoking Powershell within default.aspx.vb RRS feed

  • Question

  • User-851819717 posted

    I'm looking for some help with my default.aspx.vb script. I have a webpage which an end user will enter an ID and a file, which uploads into a directory.

    I have Powershell script which I have converted into a module, and additionally i have an module for launching Exchange Server 2010 Powershell too.

    I have tested both modules within native powershell, and they work fine.

    With regards to attempts via default.aspx.vb, the file submitted is uploaded correctly, The second part of the aspx.vb code is to run the powershell commmand, does not work, and this is captured by the exception on line 83 (Catch ex As Exception)

    Looking for advice with regards why the latter half of the code fails

    I included error logging into this aspx.vb page, for me i need to understand my modules are not loading.

    Fatal error : The term 'MailboxReport -SAID admin -TXTPATH D:\Reports\uploads\08156-20140427-145235-719' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again., please find a complete error at ErrorLog file.

    Dim Initial As InitialSessionState = InitialSessionState.CreateDefault()
    Initial.ImportPSModule(New String() {"MailboxPSTCheck", "NewExchangeSession"})
    Dim rs As Runspace = RunspaceFactory.CreateRunspace(Initial)
