如何从非托管 c++ 引用 com exe? [英] how to reference a com exe from unmanaged c++?

问题描述

我对非托管 c++ 不是很熟悉，因为我只使用过 MFC 和 Dot Net.我有一个非托管 dll，我想引用一个进程外服务器.我尝试了以下方法:

I am not very familiar with unmanaged c++, as I've only worked with MFC and Dot Net. I have an unmanaged dll that I would like to reference an out of process server. I've tried the following:

#import "C:Program Files (x86)statconnDCOMinStatConnectorSrv.exe"
using namespace STATCONNECTORSRVLib;

和

#import "C:Program Files (x86)statconnDCOMinStatConnectorSrv.tlb"
using namespace STATCONNECTORSRVLib;

STATCONNECTORSRVLib 包含对象 StatConnector.但是，当我尝试实例化 StatConnector 时，我得到一个不允许不完整的类型"，并且智能感知告诉我 StatConnector 是一个结构.

STATCONNECTORSRVLib contains the object StatConnector. However when I try to instantiate StatConnector, I get an "incomplete type is not allowed", and intellisense tells me StatConnector is a struct.

StatConnector *conn = new StatConnector();

我做错了什么?

推荐答案

假设你的 StatConnectorSrv.tlb 包含一个接口 ISomething 和一个 MyMethod 方法，以及一个 coclass Something，然后你会像这样实例化它:

Let's say your StatConnectorSrv.tlb contains an interface ISomething with a MyMethod method, and a coclass Something, then you would instantiate it like this:

#import "C:Program Files (x86)statconnDCOMinStatConnectorSrv.tlb"
using namespace STATCONNECTORSRVLib;

int _tmain(int argc, _TCHAR* argv[])
{
    CoInitialize(NULL);

    ISomethingPtr ptr(__uuidof(Something)); // create an instance of the Something coclass and get an ISomething pointer back
    ptr->MyMethod(parameters of the method);

    CoUninitialize();
    return 0;
}
