问题 By just adding a datagridview in IronPython Studio it triggers a "DataGridView' object has no attribute 'BeginInit'". Is there a fix for this? The errors are gone if the lines self._DataGridView1.BeginInit() and self._DataGridView1.EndInit() are deleted, but that's not what it should be done to fix that 回答1: There's no fix for this and there's likely not to be one because IronPython Studio isn't supported anymore. DataGridView.BeginInit is implemented explicitly and IronPython Studio is based

问题 spent some time again with the scripting interface of my app. i guess i now have an advanced dlr problem here. I have a python script I have an .NET object [o1] I call a method on the python script from .NET via Iron Python. The python code creates an object [o2] The python code calls an method on object [o1] passing [o2] as an argument (Via subclassing DynamicMetaObject) In the .NET code of the o1-method i want to dynamically call methods on o2 For example i could do that via ((dynamic)o2)

问题 After installing prerequistes (Visual Studio 2008 Shell Isolated/Integrated Mode Redistributable package) here, I still get errors: cannot find one or more components when installing IronPython Studio . What others do I require? Thx. 回答1: See how-to-use-ironpython-with-visual-studio-2008 and similar questions. It looks like IronPython Studio is supported only with outdated IronPython versions. 来源： https://stackoverflow.com/questions/1920596/ironpython-how-to-install-ironpython-studio

问题 Disclaimer : I am new to python and IronPython so sorry if this is obvious. We have a C# application that uses IronPython to execute scripts. There are a few common modules/scripts and then a lot of little scripts that define parameters, do setup, then call functions in the core modules. After some recent additions made the common modules larger performance took a hit on the imports. I attempted to fix this by making sure we only created one engine and created scopes for each script to run in

问题 I have come across a problem with IronPython that I can't solve. I need to call a function that takes a parameter of type array to value-type. The function-signature (in C++/CLI notation) is this: static int PLGServiceInterface::PLGService::MapLowSpeedRealtimeNames(cli::array<System::String ^> ^ SignalNames, int timeout_ms, cli::array<PLGServiceInterface::LVCluster_1> ^% Channels, System::String ^% ReportText) When I call the function from IronPython import clr clr.AddReferenceToFileAndPath(

问题 I am trying to use the XLRD library in IronPython 2.7 At the most basic operation of opening an .xls file (2003 format) I get the following error, and I am not sure how to fix it: workbook = xlrd.open_workbook(xlsfile) File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\xlrd\__init__.py", line 426, in open_workbook TypeError: sequence item 0: expected bytes or byte array, str found any ideas? i would like to use xlrd if possible but seems like there may be some compatibility

问题 I hope to load .net dll in ironpython. But one of static functions in .net dll, has some Named and Optional Arguments. like, Draw(weight:w,height:h, Area=1) Only can I use full arguments? 回答1: Named and optional parameters are fully supported. .NET has had these for a long time for VB.NET support and so IronPython has supported that same way to do them since the beginning. The new C# syntax maps to the same underlying metadata as the old VB support. For calling you use f(x = 42) which is

问题 I am trying to initialize a .net of custom class objects as follows: from System.Collections.Generic import List class EmployeeTree: def getEmployeeFirstName(self): return self.EmployeeFirstName def setEmployeeFirstName(self, firstName): self.EmployeeFirstName = firstName.strip() def getEmployeeLastName(self): return self.EmployeeLastName def setEmployeeLastName(self, lastName): self.EmployeeLastName = lastName.strip() def getEmployeeNumber(self): return self.EmployeeNumber def

问题 How do I access a C# class from IronPython script? C#: public class MyClass { } public enum MyEnum { One, Two } var engine = Python.CreateEngine(options); var scope = engine.CreateScope(); scope.SetVariable("t", new MyClass()); var src = engine.CreateScriptSourceFromFile(...); src.Execute(scope); IronPython script: class_name = type(t).__name__ # MyClass class_module = type(t).__module__ # __builtin__ # So this supposed to work ... mc = MyClass() # ??? me = MyEnum.One # ??? # ... but it doesn
