windows服務基礎

參考資料:<

windows服務是怎麼回事?如何建服務工程?如何除錯服務程式?

本文一一為你解答..先把**貼出來:

下面大概說一下服務的工作方法(針對這個工程):

首先,將引數"/install"或"/uninstall"傳進winmain裡分別安裝以及卸裝服務.如果不帶引數執行,就認為是服務控制管理啟動該服務程式.

接著,安裝主要做兩件事:開啟服務控制管理器(openscmanager)和建立服務(createservice).

卸裝和安裝類似:開啟服務控制管理器(openscmanager),關掉服務(controlservice(.., service_control_stop, ..;)和刪除服務(deleteservice).

假設已經安裝好了,那麼開啟"服務管理",啟動這個服務:

也可以用命令sc來做這事:

這時,由於servicemain裡有這個句,

#ifdef _debug

debugbreak();

#endif

那麼,系統就會彈出這樣的對話方塊:

選擇取消,再使用.net2003或者以上的開發工具除錯它.

下面是另乙個例子:服務是守護程序,當子程序死掉後,就啟動乙個新的子程序.
