VB, Oracle and Crystal Reports.......URGENT !!!!!

hi experts,

i'm using crystal reports ver 4.5 for reports with VB as front end and oracle as back end.  I connect with a microsoft userconnection object to oracle and perform all the sql operations. While generating the reports using the crystal Reports ocx, the method LogOnServer works fine. I use LogOffServer method in the next line, once i display the needed report as below,

CRpt.LogOffServer (connID, False)

But the vb compiler displays a message as "Expected:=" . But i'm sure that LogOffServer is not a Function but a sub and no return value can be obtained.
My versions are Crystal Report 4.5, Vb 6, oracle 8.
Please help me.......and this is urgent.

thanx in advance

I recommend reinstalling Crystal Reports.  All the DLLs you need will be installed.

Did I answer your original question?

Does it mean that the report file (.rpt) is read only?

Can you see the report?

Do you get the error messsage when you are doinging something to the report preview?

Your problem is stumping me.  Please list the VB code that sets/accesses the CRW properties, both before and after the .Action=1 statement.

oops, sorry if i'm troubling you...
this is how i've tried so far

conID% = crpt.LogOnServer("pdsodbc.dll","mydsn","","username","pass")
crpt.Action = 1
call crpt.LogOffServer(connID,False)

i write above code mnu_Report_Click() sub, i mean i need to get the report when the menu item is clicked.

But remember, i'm already connected to the DB using an user connection and it is active.

i get error at LogOffServer, when the application is run at most of the time as it cannot Log Off from the server after showing the report, as there is an active connection(user connection).

try:

crpt.LogOffServer("pdsodbc.dll", "mydsn")

pramodkumarAuthor Commented:
crpt.LogOffServer takes 2 parameters -
LogOffServer(connectionID reutrned by the LogOnServer, Bool value for logging off all active connections (True) or only the connection indiacated by the connectionID (False))
is that right????????

will the code given by you will work?????? anyway i'll try that for u.....
and need not worry about your marks......i'll may also give more than 150 !!!
thanx for staying with my question for such a long time....

The LogOffServer documentation I read had two non-optional parameters as I suggested.  My documentation might have been wrong or out of date.  It shouldn't hurt to try.  

Also, read http://support.crystaldecisions.com/communityCS/TechnicalPapers/logon_ocx.pdf

=====================================
The more I read, the more I'm inclined to suggest that you don't use the LogOnServer or the LogOffServer methods.  Just supply your userid and password with the connect string.
