The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Dynamically Changing Datasource For Crystal Report Object

Asked by afentonjm in Microsoft Visual C#.Net

Tags: crystal, report

Hi,

I'm trying to use a crystal report with .NET 2005 with C# but experiencing some problems
when trying to connect to the database to pull the data for the report. The code below
shows how I implemented the connection procedures. The problem is the code is unbale to
change which database the report connects to and defaults to the connection that was used
to design the report. The ApplyLogonToReport method does not seem to work. Can anyone help
me with the problem? The report calls a stored procedure to get the data.


private void cmdRun_Click(object sender, EventArgs e)
{
            try
            {

                SqlString user; SqlInt32 loccode;
                report = new RptTransactionDetailsCpy();

                SqlConnectionStringBuilder constr = new SqlConnectionStringBuilder(DbClient.Configuration    [DbClient.ConnectionString] as string);
                report.SetDatabaseLogon(constr.UserID, constr.Password, constr.DataSource, constr.InitialCatalog);

                ConnectionInfo info = new ConnectionInfo();
                info.AllowCustomConnection = true;

                info.UserID = constr.UserID;
                info.Password = constr.Password;
                info.ServerName = constr.DataSource;
                info.DatabaseName = constr.InitialCatalog;
                info.IntegratedSecurity = constr.IntegratedSecurity;
               

                foreach(ReportObject obj in report.ReportDefinition.ReportObjects)
                {
                    if(obj.Kind == ReportObjectKind.SubreportObject)
                    {
                        SubreportObject subObj = (SubreportObject)obj;
                        ReportDocument rd = report.OpenSubreport(subObj.SubreportName);
                        ApplyLogonToReport(rd, constr.DataSource, constr.InitialCatalog, constr.UserID, constr.Password, constr.IntegratedSecurity);
                       
                    }
                }
            }
            catch(Exception ex){}
}



public bool ApplyLogonToReport(ReportDocument rd, string server, string database, string userid, string password, bool sspi)
{
            int i = 0;
            TableLogOnInfo logonInfo = new TableLogOnInfo();
            foreach(CrystalDecisions.CrystalReports.Engine.Table table in rd.Database.Tables)
            {
                logonInfo = table.LogOnInfo;
                logonInfo.ConnectionInfo.AllowCustomConnection = true;

                logonInfo.ConnectionInfo.ServerName = server;
                logonInfo.ConnectionInfo.DatabaseName = database;
                logonInfo.ConnectionInfo.IntegratedSecurity = sspi;
                if(!sspi)
                {
                    logonInfo.ConnectionInfo.UserID = userid;
                    logonInfo.ConnectionInfo.Password = password;
                }
                table.ApplyLogOnInfo(logonInfo);

                if(sspi)
                {
                    rd.DataSourceConnections[server, database].SetConnection(server, database, sspi);
                }
                else
                {
                    rd.DataSourceConnections[server, database].SetConnection(server, database, userid, password);
                }
                i++;
                if(!table.TestConnectivity())
                {
                    return false;
                }
            }
            return (true);
}
