Database logon problem with Crystal Report

jaucourt · #1 (**permalink**) April 21st, 2004, 07:02 AM

I'm delivering a crystal report through an asp.net page, using the crystal report viewer. When testing on my machine, everything works ok, however when the page is loaded on any other machine the user is prompted to logon to the database.

I'm confused about this because I did have this problem on my own machine until I put the following line in to the setup code;

Code:

rpt.SetDatabaseLogon("dbLogon", "password")

(where rpt is the crystal report being used)

How do I overcome this problem; i.e. get the report to load without the user being prompted to log on to the database? The crystal report is one I developed outside of visual studio and then added to a project, so it sets up all it's own connections, etc. I'm using CR10

Plz take a look at http://p2p.wrox.com/topic.asp?TOPIC_ID=6389
u should login for every table u use in ur rpt file.
actually, im not sure about that & I'll be glad if there r better ways. (This was what I got from a sample in net & hope its the right way)

You can create a File DSN for an ODBC connection, edit the file in notepad to add the password, and use this File DSN as you datasource.

use this code in crystalReportViewer.

//Create the ConnectionInfos object to store the database logon Information
ConnectionInfos connInfos = new ConnectionInfos();

//Create a ConnectionInfo object for each database logon you want to set.
IConnectionInfo connInfo1 = new ConnectionInfo();

//Set the database logon information for each ConnectionInfo object.
connInfo1.setUserName("Scott");
connInfo1.setPassword("Tiger");

//Add each ConnectionInfo object to the ConnectionInfos collection.
//The ConnectionInfos object can now be used to set the database logon information for a report.
connInfos.add(connInfo1);

//Set the database logon information by passing the viewer the initialized ConnectionInfos object.
viewer.setDatabaseLogonInfos(connInfos);
viewer.setEnableLogonPrompt(false);

Hi!
I've big problems with reports and data source.

1- I create a IConnectionInfo, with all properties I want.
2- my piece of code :

Code:

viewer.setReportSource(reportSource);
ConnectionInfos connInfos = viewer.getDatabaseLogonInfos();
connInfos.clear(); //I voluntarily delete all connection info associated
                   //with the report (at the design time).
System.out.println(connInfo.getAttributes().toString());
//It prints everything OK, with all the parameters I defined in my IConnectionInfo :)
connInfos.add(connInfo); //Add my IConnectionInfo to the collection

//Here comes the trouble...
viewer.setDatabaseLogonInfos(connInfos);
System.out.println(viewer.getDatabaseLogonInfos().getConnectionInfo(0).getAttributes().toString());
//Now it prints the infos that will be used for display.
//I hoped my changes infos, and I get the design-time infos !!!! :(
//So baaaad !

//and then viewer.refresh(), processHttpRequest() and dispose()...

I followed the tutorials/examples in the PDF "CR for JBuilder"... but nothing better happen :(

The collection connInfos is OK, cleared and then have my changed settings, but the view.setDatabaseLogonInfos doesn't work.

The System.err prints on setDatabaseLogonInfos. (I printed some ##### marks just before and after the instruction, and between them, there is nothing.

I'm really desperate! I really need to change the database logon informations because I've several databases and I want to use the same report.

Hi, I am facing issue with the crystal report with dynamic databases.
Please let me brief the context here.

I have some crystal reprots (8.5) which uses ODBC to run. I am using the .Net winform to call each report. The server, database, user id and passwords are passed dynamically. But, some of the reports are failing to execute and say ".. Table not found .." error. To set the logon, I use the following code.

reportDoc.SetDatabaseLogon(userName, password, database, database);
foreach (IConnectionInfo conInfo in reportDoc.DataSourceConnections)
{
conInfo.SetConnection(serverName, database, userName, password);
}

foreach (CrystalDecisions.CrystalReports.Engine.Table table in reportDoc.Database.Tables)
{
TableLogOnInfo logOnInfo = table.LogOnInfo;
if (logOnInfo != null)
{
logOnInfo.TableName = table.Name;
logOnInfo.ConnectionInfo = connectionInfo;
table.ApplyLogOnInfo(logOnInfo);
table.Location = string.Format("{0}.dbo.{1}", database, table.Location.Substring(table.Location.LastIndexO f(".") + 1));
}
}

// Set subreport connection info
foreach (ReportDocument subreport in reportDoc.Subreports)
{
foreach (IConnectionInfo conInfo in reportDoc.DataSourceConnections)
{
conInfo.SetConnection(serverName, database, userName, password);
}
foreach (Table table in subreport.Database.Tables)
{
TableLogOnInfo logOnInfo = table.LogOnInfo;
if (logOnInfo != null)
{
logOnInfo.TableName = table.Name;
logOnInfo.ConnectionInfo = connectionInfo;
table.ApplyLogOnInfo(logOnInfo);
table.Location = string.Format("{0}.dbo.{1}", database, table.Location.Substring(table.Location.LastIndexO f(".") + 1));
}
}
}

But, even after setting this, some reports didnot executed. But i found a weired issue while debugging the code. The logon connection info is the default database set while developing the report, but while setting the connection, the database is set to "master"!!! This happens only for some of the reports. So i dont think this is a code issue.

Can anyone help on this?
