Hello,

My manager is all over me because of this issue ... please can some help me

I am working on an VB6 application which use Crystal Report 8.0.1.0 for reports and the backend database is SQL Server 2005.

My report uses stored procedure to get the records from database. The Stored Procedure access multiple database to get the records.

I am having trouble with few Crystal Reports which I am calling from VB6. The report is the cumulative report and the issue is that the crystal Report is not returning any data.

I am passing 2 parameter to the report:
1. DATE passed as varchar
2. VARCHAR

Reference in Code
1. Crystal Viewer Control (cviewer.oca)
2. Crystal ActiveX Report Viewer Library 11.0
3. Crystal Reports ActiveX Designer Run Time Library 11.0

Components used in Code
1. Crystal ActiveX Report Viewer Library 11.0 (crviewer.dll)
2. Crystal Report Control (Crystl32.OCX)



Here is the code I am using
