如何从非托管C ++引用COM EXE？

问题描述

我对非托管C ++不太熟悉，因为我只使用MFC和Dot Net。我有一个非托管的dll，我想引用一个进程外服务器。我尝试了以下操作：

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)\statconn\DCOM\bin\StatConnectorSrv.exe"
using namespace STATCONNECTORSRVLib;

和

#import "C:\Program Files (x86)\statconn\DCOM\bin\StatConnectorSrv.tlb"
using namespace STATCONNECTORSRVLib;

STATCONNECTORSRVLib包含对象StatConnector。但是，当我尝试实例化StatConnector时，出现不允许不完整的类型，并且intellisense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();

我在做什么错？

推荐答案

假设您的StatConnectorSrv.tlb包含接口 ISomething MyMethod 方法和一个协类 Something ，那么您可以这样实例化它：

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)\statconn\DCOM\bin\StatConnectorSrv.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;
}
