关于ATL的rgs注册文件

转自：http://blog.csdn.net/idiszerg/article/details/3875934

使用ATL向导的话，会在resource中产生一个rgs的注册脚本文件放在"REGISTRY"目录中用来注册组件,会在程序中通过函数DECLARE_REGISTRY_RESOURCEID(IDR_OPCSERVER)使用,IDR_OPCSERVER就是向导产生的资源文件的ID，当服务器调用CComModule::RegisterServer()时，便会使用这些脚本来载入注册表的设置，并在调用CComModule::UnregisterServer()时移除它们。所有COM的注册键都放在HKEY_CLASSES_ROOT中。

例子如下

HKCR
{
  FactorySoft.myShell.1 = s 'FactorySoft myShell'
  {
    CLSID = s '{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}'
  }
  FactorySoft.myShell = s 'FactorySoft myShell'
  {
    CLSID = s '{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}'
        OPC
        {
            Vendor = s 'FactorySoft, Inc'
        }
  }
  NoRemove CLSID
  {
    ForceRemove {C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F} = s 'FactorySoft myShell'
    {
      ProgID = s 'FactorySoft.myShell.1'
      VersionIndependentProgID = s 'FactorySoft.myShell'
      LocalServer32 = s '%MODULE%'
      {
        val ThreadingModel = s 'both'
      }
    }
  }
  NoRemove AppID
  {
    ForceRemove {C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F} = s 'FactorySoft myShell'
  }
}

HKCR 表示注册表中COM对象的注册项是HKEY_CLASS_ROOT 的缩写

NoRemove表示在反注册过程中不要删除这层注册表项；ForceRemove表示要要完全删除后面的项然后重新创建。MSDN原文如下

String Literal	Description
ForceRemove	Completely remove the following key (if it exists) and then recreate it.
NoRemove	Do not remove the following key during Unregister.
val	The following <Key Name> is actually a named value.
Delete	Delete the following key during Register.
s	The following value is a string.
d	The following value is a DWORD.

注册后的注册表主要修改如下

1、HKEY_CLASSES_ROOT/AppID/

[HKEY_CLASSES_ROOT/AppID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}]
@="FactorySoft myShell"

2、HKEY_CLASSES_ROOT/CLSID/

[HKEY_CLASSES_ROOT/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}]

"ThreadingModel"="both"

[HKEY_CLASSES_ROOT/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}/ProgID]

3、HKEY_CLASSES_ROOT/FactorySoft.myShell

[HKEY_CLASSES_ROOT/FactorySoft.myShell]
@="FactorySoft myShell"

[HKEY_CLASSES_ROOT/FactorySoft.myShell/CLSID]
@="{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}"

[HKEY_CLASSES_ROOT/FactorySoft.myShell/OPC]

[HKEY_CLASSES_ROOT/FactorySoft.myShell/OPC/Vendor]

4、HKEY_LOCAL_MACHINE/SOFTWARE/Classes/AppID

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/AppID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}]

5、HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}]

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}/LocalServer32]

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}/VersionIndependentProgID]
@="FactorySoft.myShell"

6、HKEY_LOCAL_MACHINE/SOFTWARE/Classes/

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/FactorySoft.myShell]
@="FactorySoft myShell"

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/FactorySoft.myShell/CLSID]

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/FactorySoft.myShell.1/CLSID]
@="{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}"

从中可以看出s '%MODULE%'被替换成了@="D://temp//test//Debug//myShell.exe"程序的路径
