[Ironpython-users] Integrating a WPF IPy program with C#

[Markus Schaber]

Hi, Matthew,

I think for loading the DLL, you could also use the clr module from python, it has functions like AddReference, AddReferenceToFile, AddReferenceByName and AddReferenceByPartialName.

The STA thread is always necessary for WPF and Windows Forms, AFAIK, and it has to be set at the main entry function. There’s nothing one can do later (once the application is running) about this…

Best regards

I got it sorted in the end. I’ll post what I did for completion.

To run programs that depended on WPF, two things were needed.

First, had to load the wpf dll manually into the IronPython engine’s runtime.

var wpf_path = @"C:\Program Files (x86)\IronPython 2.7\DLLs\IronPython.Wpf.dll";
var wpf_dll = Assembly.LoadFile(wpf_path);
engine.Runtime.LoadAssembly(wpf_dll);

Secondly, make the main function a STA Thread. I put this just before Main’s definition.

[STAThread]
static void Main(string[] args)

Hope this helps anyone in the future,
Matthew

It might help if you provide some code in a gist or something. Without that, its going to be difficult for anyone to help.

Hi IronPython users,

I’ve created a C# program that runs an IronPython script.
The script contains a GUI built in WPF.

When I call it using the IronPython Engine in C#,
I get the following error: “ImportError: No module named wpf”

I’ve pointed the Engine to the system path.

System.dll and mscorlib.dll have been loaded using the following code:
engine.Runtime.LoadAssembly(typeof(string).Assembly);
engine.Runtime.LoadAssembly(typeof(System.Diagnostics.Debug).Assembly);

Does anyone know where I’m going wrong and how I can sort out this import?

I’m on IPy 2.7.4.

Regards,
Matthew
