• .NET Development RemotingConfiguration.Configure ensureSecurity parameter

  The old .NET 1.1 Configure method is marked as obsolete, and recommends using a new override with a parameter ensureSecurity. The MSDN documentation on the ensureSecurity parameter is a bit laconic: " true to enable security; otherwise, false ." I want to maintain backwards compatibility, i.e. don't want to require security. But I may want to use the new security features at some time in the future. What should I set this parameter to I'm a bit confused that the decision whether to use the new security features is hardwired into the code via this parameter rather than being defined in the configuration file. ...Show All

• SQL Server Fail Execute Process Task based on batch file ERRORLEVEL?

  I am new to this, but have scoured the web and not found an answer to my question... I have an execute process task that runs a simple batch file. When this batch file completes with an ERRORLEVEL greater than 0, I would like the task to fail. I thought this simply meant setting the "FailTaskIfReturnCodeIsNotSuccessValue" property to true, and setting the SuccessValue to 0. However, this does not appear to work. Even with a simple batch file forcing the errorcode to 1 as follows, the task still completes "successfully". SET ERRORLEVEL = 1 Any ideas Thanks! I am not clear on ...Show All
