关于ATL的rgs注册文件

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 LiteralDescriptionForceRemoveCompletely remove the following key (if it exists) and then recreate it.NoRemoveDo not remove the following key during Unregister.valThe following <Key Name> is actually a named value.DeleteDelete the following key during Register.sThe following value is a string.dThe 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}]

@="D://temp//test//Debug//myShell.exe"
"ThreadingModel"="both"

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

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

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]
@="FactorySoft, Inc"

[HKEY_CLASSES_ROOT/FactorySoft.myShell.1]
@="FactorySoft myShell"

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

4、HKEY_LOCAL_MACHINE/SOFTWARE/Classes/AppID

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

5、HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID

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

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

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}/Implemented Categories/{63D5F430-CFE4-11D1-B2C8-0060083BA1FB}]

[HKEY_LOCAL_MACHINE/SOFTWARE/Classes/CLSID/{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}/LocalServer32]
@="D://temp//test//Debug//myShell.exe"

[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]
@="{C9B70C6C-2BEE-4589-96B3-01E2F4D21C9F}"

[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
