我需要在我的python项目中使用COM dll(在CSharp中制作)。 我试着遵循这个例子Using COM Objects in Scripting Languages -- Part 2 (Python),但我没有成功。
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python类时,会发生以下错误:
> Traceback (most recent call last): File "C:\Program Files
> (x86)\JetBrains\PyCharm 129.696\helpers\pydev\pydevd.py", line 1481,

错误行:
cc.GetModule((tlb_id, 1, 0))
在我的CSharp项目中,我在我的COM dll中有这个:
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!";
}
}
上面的这个COM项目,在其他应用程序中使用并且工作正常。我的问题只出现在python中。
及时:我的COM dll已在Windows注册表中注册
任何帮助?
答案 0 :(得分:3)
在这里,我找到了一个帮助我使用TLB文件来使用COM dll的提示:
Accessing unregistered COM objects from python via a registered TLB
