Hi Andy,

I have a [REPORT_NAME].deploy file on the server and it`s also
downloaded to the folder, click-once created onto the client.
I also can change the characteristic of the report from content to
embeded resource and it makes no difference. If I activate click-once,
I cannot access the report and if it`s not activated, it works.

I think the error occurs because I have this reference to my assembly
in the report. Without this everything works.
Also if I start the application from the [APPLICATION.EXE] which was
downloaded into the folder, click-once created onto the server, I can
access the report in the application. But in this why I work only
locally and the application doesn`t check for any updates.

Here a part of the code I use for the assembly and for the report:

reportViewer1.LocalReport.ExecuteReportInCurrentAppDomain(AppDomain.CurrentDomain.Evidence);

this.reportViewer1.ProcessingMode = ProcessingMode.Local;
this.reportViewer1.LocalReport.AddTrustedCodeModuleInCurrentAppDomain("[NAME_OF_THE_DLL],
Version=1.0.0.0, Culture=neutral, PublicKeyToken=[TOKEN_OF_THE_DLL]");
this.reportViewer1.LocalReport.ReportPath =
"berichte\\monatsbericht.rdlc";
this.reportViewer1.RefreshReport();

and this i have added to the DLL:

[assembly: System.Security.AllowPartiallyTrustedCallers]

Any ideas?

Thanks for your help!
