我自己写了一个dll，一切都正常，输出一个Add函数。但是下边的测试程序出错。
#include "stdafx.h"
#include <iostream>
#include <atlconv.h>

int main(int argc, char* argv[])
{
CoInitialize(NULL);
CLSID clsid;
IClassFactory *pCF;
HRESULT hr;
hr=CoGetClassObject(clsid,CLSTX_INPROC,IID_IClassFactory,(void**)&pCF);
if(FAILED(hr))
{
cout<<"函数调用失败!"<<endl;
return -1;
}
IUnknown* pUnk;
hr=pCF->CreateInstance(NULL,IID_IUnknown,(void**)*pUnk);
pCF->Release();
if(FAILED(hr))
{
cout<<"不能成功的创建对象!"<<endl;
return -1;
}
ISimpleMath* pISM=0;
pUnk->QueryInterface(IID_ISimpleMath,(LPVOID*)&pISM);
pUnk->Release();
long lRet;
pISM->Add(100,200,&lRet);
cout<<lRet<<endl;
CoUninitialize();
return 0;
}
错误列表如下：
Compiling...
testATL.cpp
d:\program files\microsoft visual studio\vc98\atl\include\atlconv.h(46) : error C2146: syntax error : missing ';' before identifier 'WINAPI'

Error executing cl.exe.

testATL.exe - 4 error(s), 0 warning(s)
请教是什么问题？

如果还不够清楚，留下email，我把程序发过去！！！谢谢各位！！

忘了，如果分少，各位尽管开口，我还有400多分，只要不超过我都可以考虑给！！！

问题可还不少啊
#include <iostream>
#include <atlconv.h>
－－》
#include <iostream>
#include <atlbase.h>
#include <atlconv.h>

[qrlvls]

#include <iostream.h>
#include <atlbase.h>
#include <atlconv.h>

int main(int argc, char* argv[])
{
CoInitialize(NULL);
CLSID clsid;
IClassFactory *pCF;
HRESULT hr;

hr = CoGetClassObject(clsid, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory,(void**)&pCF);

if(FAILED(hr))
{
cout<<"函数调用失败!"<<endl;
return -1;
}

IUnknown* pUnk;

[qrlvls]

完整版，不过你那个 ISimpleMath 怎么定义的我可就不知道了

#include <iostream.h>
#include <unknwn.h>
#include <atlbase.h>
#include <atlconv.h>

int main(int argc, char* argv[])
{
CoInitialize(NULL);
CLSID clsid;
IClassFactory *pCF;
HRESULT hr;

hr = CoGetClassObject(clsid, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory,(void**)&pCF);

if(FAILED(hr))
{
cout<<"函数调用失败!"<<endl;
return -1;
}

IUnknown* pUnk;

hr=pCF->CreateInstance(NULL, IID_IUnknown, (void**)&pUnk);
pCF->Release();
if(FAILED(hr))
{
cout<<"不能成功的创建对象!"<<endl;
return -1;
}

ISimpleMath* pISM=0;
pUnk->QueryInterface(IID_ISimpleMath,(LPVOID*)&pISM);
pUnk->Release();
long lRet;
pISM->Add(100,200,&lRet);
cout<<lRet<<endl;
CoUninitialize();
return 0;
}

clsid没有赋值啊，CoGetClassObject不知道你要创建哪个COM对象。
