晕，还是有问题，再问关于Inside COM的

自己创建COM ProxyStub工程在visual studio下，如果采用ATL模板编写COM进程外服务器（Local/Remote Server），编译器将自动生成ProxyStub(PS)的工程。利用IDL文件编译出来的相关文件可以直接编译链接成功。但是其中隐藏了很多的细节，本文从一个空的dll工程开始创建一个PS工程，并说明一下需要注意的细节。本文以《inside COM》中第十章"Servers in EXEs"中的代码为例。利用以下命令编译IDL文件serve 阅读详情

还是Inside COM第8章聚合的例子。我按照各们好友教我的方法，最后是能导出两个组件，cmpnt1.dll和cmpnt2.dll了。我是建一个cmpnt1的workspace，里面加入所有的工程，分别有，cmpnt1,cmpnt2和测试用的例子client三个工程，编译的输出都在debug文件夹下。

我编译出了cmpnt1.dll后编译cmpnt2有问题，是关于那个*.sbr文件的，我把debug下除cmpnt1.dll的所有东西都删除了，再编译，可以得到cmpnt2.dll. 然后的client工程编译时也要删除上面所说的文件，只留下cmpnt1.dll和cmpnt2.dll。最后得到了client.exe。我想调试跟踪程序的过程的，但发现
HRESULT hr = ::CoCreateInstance(CLSID_Component1,
NULL,
CLSCTX_INPROC_SERVER,
IID_IX,
(void**)&pIX) ;
这里面失败了。我想可能是我没有注册DLL吧。就用了书上带的那个Register.bat注册。

@echo off
rem
rem Register.bat
rem Registration file for Chapter 8 Example 2
rem
echo on
regsvr32 -s Cmpnt1.dll
regsvr32 -s Cmpnt2.dll

在命令行里面在debug文件夹下运行了。

D:\develop\InsideCom\Cmpent1\Debug>Register.bat

D:\develop\InsideCom\Cmpent1\Debug>regsvr32 -s Cmpnt1.dll

D:\develop\InsideCom\Cmpent1\Debug>regsvr32 -s Cmpnt2.dll

D:\develop\InsideCom\Cmpent1\Debug>

但我再试了一下，运行client.exe，也是调试着进的，还是在::CoCreateInstance这里失败了。

我上面的过程到底错在了哪里呢？麻烦会的朋友帮忙一下。谢谢！

不写bat文件，直接用cmd来注册，看看有啥错误提示没

注册表支持搜索的。

去注册表里搜索你的CLSID看看正确与否

这个我也想过，但找那些CLSID还是很麻烦的啊。

编译顺序的问题。可能在重新编译过程中，有些dll，会先被删除。

正确的顺序是，先build组件，然后注册，最后编译exe。

我的顺序是正确的，那两个DLL也还在啊。

我电脑上有atl.DLL，在system32下。我试过了这样： regsvr32 -s atl.dll

再重新到debug下运行了一次register.bat

重新运行了一次程序，但还是出现同样的错误。为什么呢？

HRESULT的值都是有固定的含义的，你可以打开winerror.h文件，查找 80040154，能得到下面的信息：

//

// MessageId: REGDB_E_CLASSNOTREG

//

// MessageText:

//

// Class not registered

//

#define REGDB_E_CLASSNOTREG              _HRESULT_TYPEDEF_(0x80040154L)

PRB: Registering ATL Server Causes 0x80040154 Error

--------------------------------------------------------------------------------
The information in this article applies to:

The Microsoft Active Template Library (ATL), versions 2.0, 2.1, 3.0, included with:
Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0

--------------------------------------------------------------------------------

SYMPTOMS
When you register an ATL server, you might get error 0x80040154 (Class not registered). For DLLs, REGSVR32.exe returns this error. For .exes, the call to _Module::RegisterServer(CComModule::RegisterServer) in _tWinMain() returns this error.

CAUSE
ATL.dll is not installed, or it is not registered.

RESOLUTION
Install ATL.dll in the Windows\System or Winnt\System32 directory and register it using REGSVR32.exe. There are UNICODE and ANSI versions of ATL.dll. Install the appropriate version on the target operating system (that is, UNICODE for Windows NT and ANSI for Windows 95 or Windows 98).

As an alternative, do not use ATL.dll. When you rebuild your ATL server with a build target of ReleaseMinDependency, the code in ATL.dll is statically linked to your project.

Even for a 'Release MinDependency' ATL.dll may need to be shipped.

For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

Q244955 PRB: MinDependency Project May Need to Include Atl.dll

STATUS
This behavior is by design.

MORE INFORMATION
ATL has a registrar component that is used during registration. This component resides in ATL.dll. During registration, the error 0x80040154 is returned from CoCreateInstance() when it fails to create the registrar component.

Location of ATL.DLL in the VC 5.0 CD:
OS\SYSTEM (UNICODE version)
OS\SYSTEM\ANSI (ANSI version)
Location of ATL.DLL in the VC 6.0 CD:
DevStudio\VC\Redist (UNICODE version)
DevStudio\VC\Redist\Ansi (ANSI version)

regsvr32 -s Cmpnt2.dll

补充一下
1.可以设置存放编译中间文件的路径和最终链接输出文件的文件夹
2.可以在Post-Build中设置自动注册
3. vc6.0也可以设置项目工程的依赖关系，只要exe项目依赖前两个dll项目，则在编译exe项目之前会自动变量所依赖的所有项目

4. CoCreateInstance调用失败，如ls说说，查看错误信息。

第一个讲得好，我记起了好像是有，谢谢

hr 的返回值是 -2147221164。但这些都是32位的返回值，怎样知道具体是什么原因的？
