PLEASE HELP ME!!!! (crystal report)

[suki]

Hi!

I use crystal reports on .net (framework 2.0).
in .net i click on my crystal report object (report.rpt)
There i can click on the report with the right mouse, select
database/set datasource location.
There i see the current data source (my xml file) :

Current data source/dsTitel (name of the dataset that is written in
this xml file)/properties/file path!

My question is:
How can i change THIS path at runtime????
I cant find it anywhere.....

Please help me, it is very urgent and i searched the whole net for
it.....

THANKS!

Just a suggestion. You probably can look through those files with
<filename>.designer.cs extension. Remember to click the show all files from
you solution explorer first.

Hi,


Super easy, just load your data in a dataset and use
ReportDocument.SetDataSource( theDataset);

you don't even need a file in the first place !

Hi!

Thanks for your answer!

I think i tried this - but since i`m not very familiar in using crystal
report -
Maybe i did something wrong..
At the moment i do not have such a dataset...
Can you tell me how to create such a dataset?
(I have to link it to my Datasource: System.Data.DataSet()
Is this possible and can you please tell me how to do this?

thanks a lot.....

Hi,

Hi!

Thanks for your answer!

What do u have?
The data I mean, where it's coming from? and in what form

Can you tell me how to create such a dataset?

Depend of the above answer, my example, I generate it from either an xml
file or from a SQL server.

(I have to link it to my Datasource: System.Data.DataSet()
Is this possible and can you please tell me how to do this?

This is a pseudocode:

//get the datasource
sqlDa.Fill ( myDS ) ; // DataAdapter
or
myDS.ReadXml( path2file, XmlReadMode.ReadSchema); //or from a file

ReportDocument myreport = new MyReportName(); //this class is named like the
..rpt you created

myreport.SetDataSource( myDS);

//readty to rock
