在Python中使用COM dll?
我需要在我的Python项目中使用一个用CSharp制作的COM DLL。
我试着按照这个例子来做:在脚本语言中使用COM对象 -- 第2部分(Python),但是没有成功。
我的Python代码是:
import sys
# for TkInter GUI support
from Tkinter import *
import tkMessageBox
import tkColorChooser
# for COM support
import comtypes.client as cc
import comtypes
# Load the typelibrary registered with the Windows registry
tlb_id = comtypes.GUID("{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}")
cc.GetModule((tlb_id, 1, 0))
当我运行这个Python类时,出现了这个错误:
> Traceback (most recent call last): File "C:\Program Files
> (x86)\JetBrains\PyCharm 129.696\helpers\pydev\pydevd.py", line 1481,

> debugger.run(setup['file'], None, None) File "C:\Program Files (x86)\JetBrains\PyCharm 129.696\helpers\pydev\pydevd.py", line 1124,

错误行:
cc.GetModule((tlb_id, 1, 0))
在我的CSharp项目中,我的COM DLL里有这些内容:
接口
[InterfaceType(ComInterfaceType.InterfaceIsDual), Guid("YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY")]
public interface ITestCOM
{
string say_hello();
}
类
[ClassInterface(ClassInterfaceType.None), Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")]
public class TestCOM : ITestCOM
{
public string say_hello()
{
return "hello world!";
}
}
这个上面的COM项目在其他应用程序中使用时运行得很好。我的问题只出现在Python中。
顺便说一下:我的COM DLL已经在Windows注册表中注册了。
有人能帮忙吗?
