Hi! Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Thank you very much! It will be helpful for us to know which platform (Windows [Mono or .NET] vs Linux) where this is happening.

runScript

I am trying to put together a basic proof of concept for running some python on the CPython interpreter from a C# host application. I have successfully invoked the RunSimpleString method on the PythonEngine class as follows: PythonEngine.Initialize(); IntPtr lockPtr = PythonEngine.AcquireLock(); var result = PythonEngine.RunSimpleString(@"print ""hello"""); PythonEngine.ReleaseLock(lockPtr); PythonEngine.Shutdown(); This worked as expected and output hello to the command prompt. I then wanted to make sure I could get a simple example working with RunString so tried the following PythonEngine.Initialize(); IntPtr lockPtr = PythonEngine.AcquireLock(); var result = PythonEngine.RunString(@"print ""hello"" print ""test"" "); PythonEngine.ReleaseLock(lockPtr); PythonEngine.Shutdown(); This just appears to do nothing and the returned result object is null. Am I getting the complete wrong end of the stick with how to use RunString? My System is: Windows 7 x64 Python 2.6.6 (64 bit) The Python .net I downloaded was pythonnet-2.0-alpha2-136-py26.zip My Visual Studio project is set to .Net 3.5 Thanks for your time, Alan
