integrating ironpython application with normal C# wpf

[braveYug]

Hello All,
I am new to python and may be I am not able to follow python basic rules. Let me explain you guys my problem and I hope i get solution of it.
I have create VS2015 ironpython solution and it works fine. I have used ironpython wpf in this.
Now i want use this ironCalc.py file with some other normal wpf C# application. I wrote code like this:

private static void externalPyt()
{
var engine = Python.CreateEngine();
var paths = engine.GetSearchPaths();
paths.Add(@"c:\Program Files (x86)\IronPython 2.7\Platforms\Net40");
engine.SetSearchPaths(paths);
var ipy = Python.CreateRuntime();
dynamic py = ipy.UseFile(@"C:\Users\praj\Documents\Visual Studio 2015\Projects\IronCalc\IronCalc\IronCalc.py");
py.start_element();
}
private void button_Click(object sender, RoutedEventArgs e)
{
externalPyt();
}

while executing this code i get exception at "dynamic py = ipy.UseFile(@"C:\Users\praj\Documents\Visual Studio 2015\Projects\IronCalc\IronCalc\IronCalc.py");"

exception says no module named wpf found. however i have already used "using IronPython.Modules". I have also added reference of ironpython.wpf , ironpython.module in c# project but still this exception doesn't go away.

Can anyone help and point out what is wrong in this code.

thanks

Is the exception from c#, or python?  Your c# doesn't look like it should be giving that error, but I don't know a whole lot about the python interface (but I do use c# daily at work, so it's not like I just glanced over your code).

Are you referencing a wpf within your python script, that you didn't import?

Hello nilamo,
As I said I am new to python as well as to this forum so let me explain again my problem with all codes using forum rules.
I have 2 solutions.
1. created by ironpython wpf with name IronCalc using interpreter Ironpython 2.7. when I run this solution it runs fine and behave as i wanted it to. Code is as follows:

import wpf
import sys
import clr
import ast
clr.AddReference("System.Windows")
from System.Windows import *
clr.AddReference("PresentationFramework")
clr.AddReference("PresentationCore")

from System.Windows import Application, Window

class MyWindow(Window):
    def __init__(self):
        wpf.LoadComponent(self, 'IronCalc.xaml')
        self.labelText.Content=''
        self.labelOut.Content=0
        
    def btnBS_Click(self, sender, e):
        labelTextLen = len(self.labelText.Content)
        self.labelText.Content = self.labelText.Content[0:labelTextLen-1]
    def btn7_Click(self, sender, e):
        self.labelText.Content=self.labelText.Content+'7'
if __name__ == '__main__':
    Application().Run(MyWindow())

2. Now I have created a C# wpf application and just want to launch previous iron python application with button created in c# wpf. While executing code I get exception that no module with name wpf Found. However in ironpython application wpf is already imported.

using System.Windows;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
using System.Diagnostics;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using IronPython.Modules;
using IronPython.Runtime;
using IronPython.Compiler;
using IronPython.Zlib;
namespace Test_PythonEmbeded
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private static void execPython()
        {
            var engine = Python.CreateEngine();
            var paths = engine.GetSearchPaths();
            paths.Add(@"c:\Program Files (x86)\IronPython 2.7\Platforms\Net40");
            engine.SetSearchPaths(paths);
            var ipy = Python.CreateRuntime();
            dynamic py = ipy.UseFile(@"C:\Users\dummy\Documents\Visual Studio 2015\Projects\IronCalc\IronCalc\IronCalc.py");
            py.start_element();
            
        }
        private void button_Click(object sender, RoutedEventArgs e)
        {
            
            execPython();
        }
    }
}

I get execption at line 32 of above code.

Error:
An unhandled exception of type 'IronPython.Runtime.Exceptions.ImportException' occurred in Microsoft.Dynamic.dll

Additional information: No module named wpf

I hope now I am able to explain my problem more clearly and hopefully will get some suggestions soon.

thanks
