Strange Exception

[jmiller]

I have a program that takes in parameters and executes a Stimulsoft report. When the utility is run from Visual Studio everything works as expected, but when the utility is run on its own I get an exception. The event log shows that it cannot load System.Data.dll. Here is the event log details.

jmill: System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.Dll' or one of its dependencies. The system cannot find the file specified.

Hello,

We found some strangeness in work of .NET Framework 4.0. In some cases, the compiled project cannot load the System.Data.dll system library, although the link to the library project is added.
You should do the following to solve this problem:
in start of your application please add the following lines of code:

Code: Select all

using System.Data;
....
DataSet ds = null;

This lines of code will be force to load System.Data library in the memory.

Thank you.

Thanks! That seems to be working - thanks again.
