Impromptu reports with .Net

Title:  Impromptu reports with .Net

I am having trouble launching Impromptu reports.  I have an ASP.Net web application and Impromptu version 6.
When the process.start line is executed, nothing happens.  In debug, there is a beep.  Impromptu does not launch.  If I double-click the vbs file in windows the macro runs just fine.

I have tried simply:  process.start("Notepad.exe").  Notepad appears in the task manager but does not open a window.

Any idea what I'm missing?

Code Behind:
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim myproc As System.Diagnostics.Process
        myproc = New System.Diagnostics.Process()
        myproc.EnableRaisingEvents = False
        Try
            myproc.Start("C:\Program Files\Cognos\cer1\samples\Impromptu\Macros\accounts.vbs")
        Catch err As Exception
            Response.Write(err.Message)
        End Try
    End Sub

.vbs file:  (this same code works fine as a macro with Impromptu open)
  CatalogLocation="q:\cp\cptools\catalogs\cattbe\test.cat"
  FileName="q:\cp\cptools\reports\rpt_tbe\test.imr"
  Set ImpAppObject = CreateObject("CognosImpromptu.Application")
  ImpAppObject.OpenCatalog CatalogLocation,"Creator","","dbusername","dbpassword"
  ImpAppObject.Visible 1
  Set ImpRepObject = ImpAppObject.Openreport(Filename)  
  ImpRepObject.RetrieveAll
  ImpRepObject.Print,,1
  ImpRepObject.CloseReport
  ImpAppObject.Quit

I did it with script. You can generate script from VB with parameters and then call impromptu report

Here si an example of a script

'IMR Reports
'Balance Sheet 2_2_8.imr
CatalogLocation = "F:\CognosApps\AR ATB\Catalog\ATB Reporting.CAT"
FileName = "F:\CognosApps\AR ATB\reports\Balance Sheet  2_2_8.imr"
Set ImpAppObject = CreateObject("Impromptu.Application")
ImpAppObject.OpenCatalog CatalogLocation, "Creator", "UserName", "UserPwd"
ImpAppObject.Visible 1
set ImpRepObject = ImpAppObject.Openreport (FileName)
'Print the report (FromPage, ToPage, Copies)
ImpRepObject.Print ,,1
ImpRepObject.CloseReport
ImpAppObject.Quit

write the txt file with a script. Include your params there and save this file as .vbs file

THen execute the vbs file (System.Diagnostic.....)

The vbs works fine stand alone.  But, when calling in the ASPNET, as below, nothing launches.  

Also, if I start("notepad.exe"), notepad appears in the task manager but does not open a window.  Are you using a windows application or a web application.  What version of Impromptu do you have installed?  Did you need to add any "Referencing" in the project?
 
Thanks
