在HKEY_CURRENT_USER中注册代理/存根 [英] Register a proxy/stub in HKEY_CURRENT_USER

问题描述

MIDL编译器使用写入HKEY_LOCAL_MACHINE的注册例程为代理/存根生成代码.有什么办法(最好是不破解MIDL生成的代码，又不绕过所有生成的代码，而使用自定义代码)在HKEY_CURRENT_USER中注册MIDL生成的p/s?

The MIDL compiler generates code for a proxy/stub with registration routines that write to HKEY_LOCAL_MACHINE. Is there any way (preferably without hacking the MIDL-generated code and without bypassing all that generated code in favor of custom code) to register a MIDL-generated p/s in HKEY_CURRENT_USER?

另外:如果p/s和COM服务器都是按用户注册的，则这样可以工作吗?我刚刚发现(经过非常令人沮丧的48小时之后)，如果按用户注册COM服务器，则在整个机器上注册的P/S将无法正常工作.具体来说，在这种情况下，p/s的异步调用逻辑(ICallFactory :: CreateCall)将失败.

Also: Will this work if both the p/s and the COM server are registered per-user like this? I just found (after a very frustrating 48 hours) that a p/s registered machine-wide will not work correctly if the COM server is registered per-user. Specifically, the asynchronous call logic (ICallFactory::CreateCall) of the p/s will fail under these circumstances.

推荐答案

使用RegOverridePredefKey是正确的答案.然后注册:

Using RegOverridePredefKey is the right answer. Then register with:

regsvr32 /n /i:user C:\src\myCode.dll

使用"/i:user"，regsvr32将您的"DllInstall"称为"DllInstall".功能而不是DllRegisterServer.

With "/i:user", regsvr32 calls your the "DllInstall" function instead of DllRegisterServer.

DllInstall的示例实现:

Example implementation of DllInstall:

extern "C" STDAPI DllInstall(BOOL bInstall, _In_opt_  LPCWSTR pszCmdLine)
{
    HRESULT hr = E_FAIL;
    static const wchar_t szUserSwitch[] = L"user";

    if (pszCmdLine != NULL)
    {
        if (_wcsnicmp(pszCmdLine, szUserSwitch, _countof(szUserSwitch)) == 0)
        {
            ATL::AtlSetPerUserRegistration(true); // is this really needed??
        }
    }

    LSTATUS status = RegCreateKeyEx(HKEY_CURRENT_USER, L"SOFTWARE\\Classes", 0, 0, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 0, &hkcu_classes, &disposition);
    if (status == ERROR_SUCCESS)
    {
        status = RegOverridePredefKey(HKEY_CLASSES_ROOT, hkcu_classes);
    }
    hr = HRESULT_FROM_NT(status);

    if (SUCCEEDED(hr))
    {
        if (bInstall)
        {
            hr = DllRegisterServer();
            if (FAILED(hr))
            {
                DllUnregisterServer();
            }
        }
        else
        {
            hr = DllUnregisterServer();
        }
    }
}
