Invalid Procedure Call

[openpro]

I am using a DLL compiled in VB6 that references the CRAXDRT.DLL (crystal reports object) to print reports. This is being utilised by several users from a windows 2k server via ASP pages on an intranet.
This works perfectly well for a period of time, then starts to get an ‘Error 5 Invalid Procedure Call or Argument’ on the line
‘Set crxApp = New CRAXDRT.Application’.

Code used:
Dim crxApp As CRAXDRT.Application
Dim crxReport As CRAXDRT.Report
Set crxApp = New CRAXDRT.Application
Set crxReport = crxApp.OpenReport(xxxx)
With crxReport.Database.Tables(1)
.SetLogOnInfo &quot;&quot;, &quot;&quot;, &quot;<<Use Integrated Security>>&quot;, &quot;&quot;
End With
crxReport.PrintOut False
Set crxReport = Nothing
Set crxApp = Nothing

The crystal report is saved with an OLE DB connection to the database because integrated security is used.
A reboot of the server clears the problem for a period of time before it re-appears, this points to memory leakage but it only affects crystal reports.
Any ideas would be appreciated.

If this is happening after a period of time, maybe it has to do with the concurrent liscencing issue? I don't recall offhand, but I am fairly certain that CE only ships with 5 concurrent liscences - which may mean that your application is using these liscences and not giving them back (causing the error). I think there was some form of server setting that you could use to define how long a liscence would be in use before it gets returned. Could someone confirm this (or disprove it, whichever is right )
