for WPF. The improvements made for IronPython beta 8 make this a lot easier
thanks to several new functions on the PythonEngine: ExecuteToConsole,
FormatException and ParseInteractiveInput.</span></font><o:p></o:p></p>

delegate from the FormatException method as the comment seems to indicate. I
think it’s very useful to filter my own C# application from the stack

FilterStackFrame?</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

SetGlobal with a SymbolId. Am I correct to use SymbolTable.StringToId(name) to
generate a SymbolId? It used to be easier with just a string to specify the

was a way to directly call a Python function loaded in the engine and pass
