Dear Velu,

I was searching some information from the crystal report support site.

before go that article, check the solution which i give below...

make it use according to your project / product

And I found this article,


With the same idea, is it mean that there is no way to access two or
more databases from a singal crystal report template?

so, am not sure, try to implement...

to make 2 diff connection to call two database.. i don't how u develop the source, if u tell that the way of source code, i ill help u sure...

check this...

Code: [Select]
CrystalReport1.LogonInfo(0) = "dsn=DB1; uid=ID; pwd=password"
CrystalReport1.LogonInfo(1) = "dsn=DB2"
CrystalReport1.ReportFileName = "1.rpt"

another method:

and one more thing if it possbile use 2 different database to call in single report.

If u have a report template "itacumens.rpt" requires data from 2 different databases, MSSQL and MSAccess. When u make the connect
individually on each database, they both work very well. However, it isn't make sense to me that I can make 2 connections in the same
CrystalReport object.

Are there any methods to handle this sort of situation? try this code..

Code: [Select]
Private Sub Command1_Click()
   With CrystalReport1
       '* works with SQL server *
     .Connect = "dsn=myLocalSQLDB;uid=myID;pwd=myPassword"    'works
     '.ReportFileName = "C:\Report_SqlSers.rpt"               'works
       '* works with MSAccess *
     .Connect = "dsn=myLocalAccessDB"                         'works
     '.ReportFileName = "C:\Report_MSAccess.rpt"              'works
       '/* Both */
     .ReportFileName = "C:\Report_both.rpt" 
       'with runtime error, due to re-assign value as the
       'parameter to the connection, I believe?
     .WindowHeight = 600
     .WindowWidth = 800
     .Action = 1
End With     
End Sub
