which argtypes for NetShareAdd

阅读更多关于 which argtypes for NetShareAdd

The win32 function NetShareDel takes three arguments, LPCWSTR LPCWSTR and DWORD. So I use the following list for argtypes: C.windll.Netapi32.NetShareDel.argtypes = [LPCWSTR, LPCWSTR, c_int] C.windll.Netapi32.NetShareDel.restype = c_int C.windll.Netapi32.NetShareDel(server, shareName, 0) That works fine, but I can't figure out what to use for NetShareAdd, especialle the byte array for NET_SHARE_INFO struct and the last byref(c_int) argument. Here's the code: def Share(server, shareName, dir): info = SHARE_INFO_2() STYPE_DISKTREE = 0 info.shi2_netname = shareName info.shi2_path = dir info.shi2

Distributing IronPython applications

阅读更多关于 Distributing IronPython applications

问题 I'm thinking of developing a small application using IronPython, however I want to distribute my app to non-techies and so ideally I want to be able to give them a standard shortcut to my application along with the instructions that they need to install IronPython first. If possible I even want my shortcut to detect if IronPython is not present and display a suitable warning if this is the case (which I can do using a simple VbScript) The trouble is that IronPython doesn't place itself in the

Using `dynamic` keyword in C# doesn't compile

阅读更多关于 Using `dynamic` keyword in C# doesn't compile

问题 I'm trying to compile a piece of C# code that contains the dynamic keyword. (I need this keyword for using ironpython.) However, it doesn't compile, complaining that error CS1980: Dynamic keyword requires `System.Runtime.CompilerServices.DynamicAttribute' to be defined. Are you missing System.Core.dll assembly reference? The compiler I'm using is Mono JIT compiler version 2.10.8.1 . I don't have System.Runtime.CompilerServices.DynamicAttribute in the list of possible references. How can I

问题 I'm trying to access .Net(C#) enums in IronPython, lets say we have Test.dll // Contains Several Enums enum TestType{..} enum TestQuality{..} .... .... enum TestStatus{..} //Similarly Multiple functions public void StartTest(TestType testType, TestQuality testQuality){..} .... .... public TestStatus GetTestStatus(){..} and now if I try to call the above functions, I need to choose the appropriate enum parameters and so far what I did is this, Iron Python [vs2012] import clr clr.AddReference(

Pass a C# Class Object to a Python file

阅读更多关于 Pass a C# Class Object to a Python file

问题 Okay... I'm trying to pass an Object which I declare in C# to a Python file with IronPython. So this is what I was thinking off: C# class: public class ParamObj { private string Obj_String; private int Obj_Int; public ParamObj(string lObjS, string lObjI) { Obj_String = lObjS; Obj_Int = lObjI; } public string getString() { return Obj_String; } public int getInt() { return Obj_Int; } public setString(string lStr) { Obj_String = lStr; } public setInt(int lInt) { Obj_Int = lInt; } } So i have my

Performance of Mass-Evaluating Expressions in IronPython

阅读更多关于 Performance of Mass-Evaluating Expressions in IronPython

问题 In an C#-4.0 application, I have a Dictionary of strongly typed ILists having the same length - a dynamically strongly typed column based table. I want the user to provide one or more (python-)expressions based on the available columns that will be aggregated over all rows. In a static context it would be: IDictionary<string, IList> table; // ... IList<int> a = table["a"] as IList<int>; IList<int> b = table["b"] as IList<int>; double sum = 0; for (int i = 0; i < n; i++) sum += (double)a[i] /

IronPython - JSON choices

阅读更多关于 IronPython - JSON choices

问题 What is the best way to deal with JSON in IronPython 2.0.1. The native Python "standard library" json looks to be not implemented yet. If I wanted to use the Newtonsoft Json.NET library how do I do this? I could add the assembly to the GAC, but what are my other choices? 回答1: This link provides an overview of the ways to add refernces to .Net dlls with IronPython: Haibo Luo's weblog : IronPython: clr.AddReference So, for example, if you'd likle to avoid placing the Json.NET library in the GAC

Importing mgcv fails because Rlapack.dll cannot be found

阅读更多关于 Importing mgcv fails because Rlapack.dll cannot be found

问题 I want to link to the R statistical package in IronPython by using the R.NET library. It's been working fine, but now I need to use R's mgcv library. Importing mgcv fails (import is done with the command rdn.r.EagerEvaluate("library(mgcv)") , where rdn is an IronPython object that wraps the R.NET library). When the import fails, Windows opens a dialog box that says: "The program can't start because Rlapack.dll is missing from your computer. Try reinstalling the program to fix this problem."

execute a python script in C#

阅读更多关于 execute a python script in C#

问题 I am trying to execute a python code in C#. Normally it should be done using IronPython and after installing PTVS (I'm using VS 2010). var pyEngine = Python.CreateEngine(); var pyScope = pyEngine.CreateScope(); try { pyEngine.ExecuteFile("plot.py", pyScope); } catch (Exception ex) { Console.WriteLine("There is a problem in your Python code: " + ex.Message); } The problem is that it seems that IronPython doesn't recognize some libraries like numpy, pylab or matplotlib. I took a look a little

阅读更多关于 C# / IronPython Interop and the “float” data type

问题 Working on a project that uses some IronPython scripts to as plug-ins, that utilize functionality coded in C#. In one of my C# classes, I have a property that is of type: Dictionary<int, float> I set the value of that property from the IronPython code, like this: mc = MyClass() mc.ValueDictionary = Dictionary[int, float]({1:0.0, 2:0.012, 3:0.024}) However, when this bit of code is run, it throws the following exception: Microsoft.Scripting.ArgumentTypeException was unhandled by user code
