我怎么配置DCOM将我的DLL加载到一个单独的进程？ [英] How exactly do I config DCOM to load my DLL into a separate process?

问题描述

我试图强制一个现有的本地C + ATL in-proc COM服务器进入一个单独的进程。我希望DCOM可以为我做这个而不改变COM服务器。

I'm trying to force an existing native C++ ATL in-proc COM server into a separate process. I hope DCOM can do this for me without changing the COM server.

我开始与一个通常的注册表设置 - 我有一个HKCR\CLSID {classId}条目和InProcServer32键，其中指定.dll文件的路径。

I started with a usual registry setup - I have a HKCR\CLSID{classId} entry and an InProcServer32 key there specifying the path to the .dll file.

我生成了一个应用程序ID（GUID），并将其添加到此处。具体来说，我在HKCR\CLSID {classId}下添加了一个等于应用程序ID的字符串值AppId。我还添加了一个HKCR\AppId {applicationId}键和一个等于空字符串的字符串值DllSurrogate。我认为这足以强制我的COM服务器进入默认的系统提供的代理。

I generated an application id (GUID) and added it here and there. Specifically I added a string value "AppId" under HKCR\CLSID{classId} equal to the application id. I also added a HKCR\AppId{applicationId} key and a string value "DllSurrogate" equal to an empty string. I thought it would be enough for forcing my COM server into a default system-provided surrogate.

DCOM应用程序出现在DCOM配置控制台中。但是当我调用 CoCreateInstance（）或 CoGetClassObject（）并提供类id和 CLSCTX_LOCAL_SERVER 它返回类未注册。我做错了什么？

The DCOM application appears in the DCOM configuration console. However when I call CoCreateInstance() or CoGetClassObject() and provide the class id and CLSCTX_LOCAL_SERVER it returns "Class not registered". What am I doing wrong?

UPD：已解决。所采取的步骤足以使它工作除了我正在编辑错误的类ID，由于某种原因在InProcServer32键下有相同的路径 - 也许这是一个COM地狱问题。

UPD: Resolved. The steps taken were enough to make it work except that I was editing the registry for the wrong class id that for some reason had the same path under InProcServer32 key - perhaps that was a COM hell issue.

推荐答案

按照检查列表：

1. 必须在注册表中的CLSID键下指定AppID值，相应的AppID密钥。 （已选中）


2. 在激活调用中， CLSCTX_LOCAL_SERVER 位置1且CLSID键不指定LocalServer32，LocalServer或LocalService。 （选中）


3. CLSID键包含InprocServer32子项。 （选中）


4. InprocServer32键中指定的代理/存根DLL存在。


5. DIDSurrogate值位于AppID键下方。 （已选中）

1. There must be an AppID value specified under the CLSID key in the registry, and a corresponding AppID key. (checked)
2. In an activation call, the CLSCTX_LOCAL_SERVER bit is set and the CLSID key does not specify LocalServer32, LocalServer, or LocalService. (checked)
3. The CLSID key contains the InprocServer32 subkey. (checked)
4. The proxy/stub DLL specified in the InprocServer32 key exists. ???
5. The DllSurrogate value exists under the AppID key. (checked)
