Help with using Crystal Report with XML data source

Hello,

I'm gettimg prompted for a password eventhough my XML datasource is not password protected.  Can you help me fix this problem? The code below is what I've tried, but it still doesn't work. I'm using VB.NET with crystal report 2008.

Thanks,

V.

Dim xyzcal As String
        xyzcal = Trim(TextBox1.Text)
        Dim myaop29report As New AOP29_XML
        Dim myaop6viewer As New AOP6VIEWER
        Dim mySQL_Statement As String

        Dim fs1 As System.IO.FileStream
        fs1 = New System.IO.FileStream(Application.StartupPath + "\Link.xml", IO.FileMode.Open)
        mySQL_Statement = "{Link.Receiver_ID}in [" & xyzcal & "]"
        Dim myDataAdapter As New Xml.XmlTextReader(fs1)
        Dim dtset1 As New DataSet
        dtset1.ReadXml(fs1)
        myaop29report.SetDataSource(dtset1)
        myaop29report.SetDatabaseLogon("admin", "")
        With myaop6viewer
            .CrystalViewer1.ReportSource = myaop29report
            myaop29report.RecordSelectionFormula = mySQL_Statement
            .Show()
        End With
        MsgBox(myaop29report.RecordSelectionFormula)
        Me.Cursor = Cursors.Default
        myaop29report = Nothing

Is this where the problem is occurring?:
myaop29report.SetDatabaseLogon("admin", "")

If so try sending a dummy password i.e.:
myaop29report.SetDatabaseLogon("admin", "Dummy")

Havent tested this but worth a try.

No, that is not the Location. I don't get an error message, just a prompt for login data. Dummy did not work. Do you have another suggestion?

Yes, data source is xml.

When you created the report, did you do so against an XML file or against a database?

Thanks for the source code, the source of my report is .xml instead of .xsd, could that be the problem?

Hi,

Below is an example of the data source (Three xml files, donor.xml and receiver.xml are linked by link.xml) The report displays the values of Domors and recivers based on their id field in the link file.
The report works alone, but doesn't work with vb.net. Is something wrong with the files' format for .net?

Donor:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Row>
            <Donor_ID>1</Donor_ID>
            <Donor>BEL</Donor>
      </Row>
      <Row>
            <Donor_ID>2</Donor_ID>
            <Donor>CAN</Donor>
      </Row>
      <Row>
            <Donor_ID>3</Donor_ID>
            <Donor>CZE</Donor>
      </Row>
      <Row>
            <Donor_ID>4</Donor_ID>
            <Donor>DNK</Donor>
      </Row>
      <Row>
            <Donor_ID>5</Donor_ID>
            <Donor>USA</Donor>
      </Row>
</Root>

Link.xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Row>
            <Receiver_ID>1</Receiver_ID>
            <Donor_ID>2</Donor_ID>
            
      </Row>
      <Row
            <Receiver_ID>3</Receiver_ID>
            <Donor_ID>4</Donor_ID>
      </Row>
</Root>


Receiver:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <Row>
            <Receiver_ID>1</Receiver_ID>
            <Receiver>FRA</Receiver>
      </Row>
      <Row>
            <Receiver_ID>2</Receiver_ID>
            <Receiver>GBR</Receiver>
      </Row>
      <Row>
            <Receiver_ID>3</Receiver_ID>
            <Receiver>NLD</Receiver>
      </Row>
      <Row>
            <Receiver_ID>4</Receiver_ID>
            <Receiver>DEU</Receiver>
      </Row>
      <Row>
            <Receiver_ID>5</Receiver_ID>
            <Receiver>USA</Receiver>
      </Row>
</Root>

Most XML files also include the data whereas the XSD is only the database definition.

I think that is the issue.  You want to build th ereport against the data definition then pass it the dataset.  That said, I am not sure there is much difference in using the XML file rather than simply the XSD.

Hello,
How do you obtain an xsd from an xml? How do you design the report with the xsd? and how do you pass the data using a dataset to the xsd?
Thanks,
V.

mlmccCommented:
I think the example linked above shows how to use the XSD file.

I don't know how to build an XSD file.
