ello,

I have been having issues with auto logon for crystal report viewer and visual studio.

The following code is im using to auto logon and pass on parm values and this is all inside Page_Load:

C#

pono.Text = Request.QueryString["PONU"];
mrrr.Text = Request.QueryString["MRNU"];


//login so users wont have to enter user/pass all the time
ReportDocument cryRpt = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables;

cryRpt.Load("~/reports/MatRecReport-new.rpt");

crConnectionInfo.ServerName = "e40";
crConnectionInfo.DatabaseName = "";
crConnectionInfo.UserID = "user";
crConnectionInfo.Password = "pss";

CrTables = cryRpt.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
{
    crtableLogoninfo = CrTable.LogOnInfo;
    crtableLogoninfo.ConnectionInfo = crConnectionInfo;
    CrTable.ApplyLogOnInfo(crtableLogoninfo);
}

And this is the error i get:

Server Error in '/' Application.

Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack. 
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.Runtime.InteropServices.COMException: Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack.

Line: cryRpt.Load("~/reports/MatRecReport-new.rpt");

How can i load the report thats in the project folder itself?

From what you have shown the problem will be due to how your path is being resolved.
The ~ character refers to the home directory of the application on your web server, for instance;

HTML

http://localhost:1234

To confirm if your path is valid you can just enter the path to the file in your web browser (with the solution running of course) as follows;

HTML

http://localhost:1234/reports/MatRecReport-new.rpt

If you are prompted to save or open the file your path is correct.

Once your path is correct, you will need to use Server.MapPath as follows;

C#

cryRpt.Load(Server.MapPath("~/reports/MatRecReport-new.rpt"));

Kind Regards
