I have been trying to debug this sample code, but I am having trouble.

Here is the code:

import System
import get_events_devices
from System.Windows.Forms import *
from System.ComponentModel import *
from System.Drawing import *
from clr import *
clr.AddReference("IronPython") 

class Check: # namespace

    class Form1(System.Windows.Forms.Form):
        """type(_label1) == System.Windows.Forms.Label, type(_button1) == System.Windows.Forms.Button"""
        __slots__ = ['_label1', '_button1']
        def __init__(self):

            self.InitializeComponent()

        @accepts(Self(), bool)
        @returns(None)
        def Dispose(self, disposing):

            super(type(self), self).Dispose(disposing)

        @returns(None)
        def InitializeComponent(self):
            self._button1 = System.Windows.Forms.Button()
            self._label1 = System.Windows.Forms.Label()
            self.SuspendLayout()
            # 
            # button1
            # 
            self._button1.Location = System.Drawing.Point(58, 61)
            self._button1.Name = 'button1'
            self._button1.Size = System.Drawing.Size(75, 23)
            self._button1.TabIndex = 0
            self._button1.Text = 'Click'
            self._button1.UseVisualStyleBackColor = True
            self._button1.Click += self._button1_Click
            # 
            # label1
            # 
            self._label1.AutoSize = True
            self._label1.Location = System.Drawing.Point(190, 70)
            self._label1.Name = 'label1'
            self._label1.Size = System.Drawing.Size(0, 13)
            self._label1.TabIndex = 1
            # 
            # Form1
            # 
            self.ClientSize = System.Drawing.Size(292, 273)
            self.Controls.Add(self._label1)
            self.Controls.Add(self._button1)
            self.Name = 'Form1'
            self.Text = 'Form1'
            self.ResumeLayout(False)
            self.PerformLayout()

        @accepts(Self(), System.Object, System.EventArgs)
        @returns(None)
        def _button1_Click(self, sender, e):

            # Snippet Statement
            pass
            # End Snippet Statement
            self._label1.Text = 'mohsin'
            get_events_devices.units()

I have just added optparse.py, get_events_devices.py, and iron python.dll.

From where I get ironpython_module.dll as I have install Iron Python I am not getting this .dll?

Any ideas?


If you are running and debugging the Python code using Visual Studio via the IronPython tools, it might be that your sys.path does not contain a reference to all of the IronPython modules such as os.

In your code, try adding the following to indicate the install directory of IronPython:

import sys
sys.path.append(r"C:\Program Files\IronPython 2.7\Lib")

The above is a workaround for this reported bug.

There is a project FePy[^] that provides  The IronPython implementation does not come with xml.parsers.expat.However, there is a workaround.

In the python scripts, you need explicitly import lib path of os.py
