Is it possible to preload assemblies before they are called? Each time

Here you go...
' load up crystal when the app starts up.
' use a separate thread since its such a pig.
TraceWriteLine("starting Crystal Reports Thread")
myTimer = New FunctionTimer("load crystal")
Dim t As New Thread(AddressOf LoadCrystal)
t.Priority = ThreadPriority.BelowNormal
t.Start()
myTimer.EndTimer()
TraceWriteLine("...thread started")
' here's the code to load up a dummy report.
' this seems to load up and keep everything in memory throughout the
life of the app.
Public Sub LoadCrystal()
crReport = New ReportDocument
Try
' Need to preload crystal engine so the reports will print
quickly throughout the rest of the application.
' This report is not used, it is just loaded. Testing so
far 12/23/04 has not shown any
' problems such as memory or print errors.
crReport.Load(CrystalReportFolder & "rptBlank.rpt")
Catch ex As Exception
DisplayException(ex, "Error: Could find the startup Crystal
Report named 'rptBlank.rpt'." & _
vbCrLf & "If you are a new user, you may lack Server
permissions to read this directory and file: " & CrystalReportFolder &
"rptBlank.rpt" & _
vbCrLf & "Or the report may have been deleted or

End Try
End Sub
