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;
}
