hi All, I have embedded pythonnet into my C# application and this works great as far as creating .net objects from python, executing methods etc. Here I am using the RunSimpleString (the PyRun_SimpleString) wrapper to send commands from the C# application to the pythonnet. However I am facing the following problems: 1. After RunSimpleString, PyErr_Occurred or PyErr_Fetch are not able to detect any exceptions even if they did occur - for example, consider the code - curErr = PythonEngine.RunSimpleString( "10/0\n"); - this code does return a -1 value indicating error. - however after this none of PyErr_Occurred or PyErr_Fetch do not detect this error - from python documentation it looks like there is no way to obtain the exception information 2. using RunString - because of above problem I want to send a multi-line code including a try-except: block - I have tried using RunString with all the three modes - Py_eval_input, Py_single_input and Py_file_input - The RunString works only if the code does not have any .net objects or does not include any .net exceptions - If the code sent to RunString includes a .net object e.g. obj, then RunString always returns in NameError, obj is not defined 3. Strangely, if I run the console application, it is able to work with .net exceptions - both .net and user defined exceptions 4. Is this because of the new dictionary created while in RunString? thanks Sesh Cherukuri
