ATL ActiveX 非管理员权限发布（支持vs2005)

在win7系统中，vs2005开发的atl activex需要管理员权限才能注册。

解决方法：

PerUserRegistration.h

#pragma once

class PerUserRegistration
{
public:
    PerUserRegistration(bool perUser = true);
    ~PerUserRegistration();

private:
#if _ATL_VER < 0x0900
    static void EnablePerUserTLibRegistration();
    bool m_mapping;
#endif
};

#include "PerUserRegistration.h"
#include <Windows.h>
#include <assert.h>

PerUserRegistration::PerUserRegistration(bool perUser)
#if _ATL_VER < 0x0900
: m_mapping(false)
#endif
{
#if _ATL_VER < 0x0900
    // this seems to be always active and therefore may break
    // any COM functionality thats not registered per user

    if (!perUser)
    {
        return;
    }

    HKEY key;

    LONG err = ::RegOpenKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Classes"), , MAXIMUM_ALLOWED, &key);
    if(err == ERROR_SUCCESS) {
        err = ::RegOverridePredefKey(HKEY_CLASSES_ROOT, key);
        ::RegCloseKey(key);
    }

    if (err == ERROR_SUCCESS) {
        EnablePerUserTLibRegistration();
        m_mapping = true;
    }
#else // _ATL_VER >= 0900
    AtlSetPerUserRegistration(perUser);
#endif
}

#if _ATL_VER < 0x0900
void PerUserRegistration::EnablePerUserTLibRegistration()
{
    HMODULE hOleaut32 = ::GetModuleHandle(TEXT("Oleaut32.dll"));
    assert(hOleaut32);

    typedef void (WINAPI * EnablePerUserTLibRegistrationProcPtr) (void);
    EnablePerUserTLibRegistrationProcPtr enablePerUserTLibRegistrationProcPtr =
        reinterpret_cast<EnablePerUserTLibRegistrationProcPtr>(
        GetProcAddress(hOleaut32, "OaEnablePerUserTLibRegistration"));
    if (enablePerUserTLibRegistrationProcPtr) {
        enablePerUserTLibRegistrationProcPtr();
    }
}
#endif

PerUserRegistration::~PerUserRegistration()
{
#if _ATL_VER < 0x0900
    if (m_mapping)
        ::RegOverridePredefKey(HKEY_CLASSES_ROOT, NULL);
#endif
}

然后在ActiveX程序中使用：

// DllRegisterServer - 将项添加到系统注册表
STDAPI DllRegisterServer(void)
{
    PerUserRegistration perUser(true);

    // 注册对象、类型库和类型库中的所有接口
    HRESULT hr = _AtlModule.DllRegisterServer();
#ifdef _MERGE_PROXYSTUB
    if (FAILED(hr))
        return hr;
    hr = PrxDllRegisterServer();
#endif
    return hr;
}

// DllUnregisterServer - 将项从系统注册表中移除
STDAPI DllUnregisterServer(void)
{
    PerUserRegistration perUser(true);

    HRESULT hr = _AtlModule.DllUnregisterServer();
#ifdef _MERGE_PROXYSTUB
    if (FAILED(hr))
        return hr;
    hr = PrxDllRegisterServer();
    if (FAILED(hr))
        return hr;
    hr = PrxDllUnregisterServer();
#endif
    return hr;
}

这样就可以了，不是管理员也可以正常注册使用了。
