hi guys,

I use Crystal Report control in my VB app to plot a chart with data from a database (mdb) located at app.path. At design time I specified the database location inside Crystal Report Designer in VB like this:- "Designer -> Database Fields -> Set Locaton -> File: ChartData!.\DBName.mdb". I believe the ".\" equivalent to App.Path. And I plot the chart using Chart Expert at design time. This approach works fine in Windows 98, NT and 2000. However, in XP, it gives me the follow error: File could not be found: "ChartData", at file location: "ChartData". Is there anyway I can specify the DB location and plot the chart at runtime using VB code instead of at design time. Thanks in advance! :)

Yes there is.  What controls are you using in VB to call the report?

It sounds like the RDC.

The RDC object has a SetDataSource method.

yes, I use RDC.

After I specified the location of the Database, how can I plot the chart programmatically? At design time I can use the Chart Expert but how about at runtime??

mlmcc,

I found out from one of the articles on the site you gave me. This is all I needed:

Report.Database.Tables(1).Location = "C:\myDatabase.mdb"

Thanks!

Still can't find anything about plotting a chart programmatically though. If you have any information on that please let me know. Later.
