? ? 我在開發的時候用到了DLL里面的函數，開始的時候采用的靜態導入的方法，但是發現服務開機啟動以后就死掉了，這里不是DLL路徑的問題。

?? 沒辦法，自己只得用動態導入的方法，還好，服務自動開機運行了，還算正常吧。

?? 小提示：如果需要彈出MessageBox消息，比如讓服務可以與桌面進行交互。? 這個在服務里面可以設置。

???? 當然，我這里的初始化參數已經設置好了，在DOS命令里面安裝完成后，你會發現，那個框，我已經替你選上了。

???

???? //重要說明，服務最好不要直接編譯執行，雖然是exe，最好的方式是安裝，?

???????? ?安裝命令??? DOS? 下：?? ServiceName.exe???? /install

????????? 卸載命令?? DOS下 ：ServiceName.exe??????/uninstall????

???? ??直接運行exe不僅會報錯，還會導致服務開機不能自動運行。

???? 大多的時候，你直接運行exe都會報1063錯誤，就是因為你把服務以控制臺的方式運行了。?
