ATL建立COM服務時必須注意的問題

1:用ATL嚮導建立COM元件時,必須指定ProgID

2:ATL嚮導生成的RGS有BUG,必須手工新增一句 

val AppID = s '%APPID%'
像下面這樣
HKCR
{
	ProgIDMyInterface.1 = s 'CMyInterface Class'
	{
		CLSID = s '{5B91E508-D66E-4F27-A371-E0D5FC3AAA0B}'
	}
	ProgIDMyInterface = s 'CMyInterface Class'
	{		
		CurVer = s 'ProgIDMyInterface.1'
	}
	NoRemove CLSID
	{
		ForceRemove {5B91E508-D66E-4F27-A371-E0D5FC3AAA0B} = s 'CMyInterface Class'
		{
			ProgID = s 'ProgIDMyInterface.1'
			VersionIndependentProgID = s 'ProgIDMyInterface'
			ForceRemove Programmable
			LocalServer32 = s '%MODULE%'
			{
				val ServerExecutable = s '%MODULE_RAW%'
			}
			val AppID = s '%APPID%'
			TypeLib = s '{E57E6FF7-264C-4753-8393-FF512A651C7B}'
			Version = s '1.0'
		}
	}
}

否則,客戶端在使用CoCreateInstance建立服務形式的COM元件時會返回伺服器啟動失敗的詭異的問題
