thanks for your reply. I had the necessary imports in place but was still seeing the error. The following code from Michael Eddington resolved the issue (I think the current problem is because of the dictionary being used)
public static PyObject RunString(string code)
       {
               PyObject module = ImportModule("__main__");
               PyDict globals = new PyDict(Runtime.PyModule_GetDict(module.Handle ));

       if (locals == null)
       {
           locals = new PyDict(Runtime.PyDict_New());
       }

                       Runtime.Incref(globals.Handle);
                       Runtime.Incref (locals.Handle);
       IntPtr result = Runtime.PyRun_String(code, (IntPtr)257,
globals.Handle, locals.Handle);

       if (result == IntPtr.Zero)
       {
           return null;
       }

       return new PyObject(result);
   }

e.g.

  CLR.Food.SpamAndEggs.cook()

  ...will fail

but

  import CLR
  import CLR.Food
  CLR.Food.SpamAndEggs.cook()

  ...should work

hope this helps,

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

[Python.NET] Problem with DateTimePicker control

Hi, I have problems setting the Value of a DateTimePicker control of Windows Forms. The Value property *is* set (I can print it), but if displayed only the current date is shown in the control, not the value I have set the Value property set to before. The python version is 2.3, the .net versions tested are 1.1 and 2.0. Here are some code snippets: #----------------------------------------------------------------------- def dt2SysDt(dtFrom, incr = 0): #----------------------------------------------------------------------- "python date/dateTime in .net-DateTime(Date) umwandeln" return (System.DateTime(dtFrom.year, dtFrom.month, dtFrom.day) .AddDays(incr)) #----------------------------------------------------------------------- def sysDt2Dt(dtFrom, incr = 0): #----------------------------------------------------------------------- ".net-DateTime(Date) in python dateTime.date umwandeln" dtFrom = dtFrom.AddDays(incr) rv = datetime.date(dtFrom.Year, dtFrom.Month, dtFrom.Day) #print "sysDt2Dt=", rv return rv .... # set the value self.dtpErzeugtVon.Value = dt2SysDt(src.dtErzeugtAb) # display the values of dtp's for ctl in (self.dtpErzeugtVon, self.dtpErzeugtBis, self.dtpVersendetVon, self.dtpVersendetBis): print "dtp...=", ctl.Name, ctl.Value, sysDt2Dt(ctl.Value) # the print statement shows the following ... dtp...= dtpErzeugtBis 31.03.2007 00:00:00 2007-03-31 ... When the form is shown with ShowDialog(), only the current date is show (march 7 instead of march 31). Does anyone have an idea?
