嗨我的QT C++程序中的任務計劃程序API存在問題。我使用登錄觸發器示例代碼here。任務計劃程序API錯誤80041318
我得到的第一個錯誤是CoInitializeSecurity失敗：RPC_E_TOO_LATE這意味着
CoInitializeSecurity已經被調用。根據here。所以我評論了coinitializesecurity調用，並解決了這個問題。
但是現在我在嘗試執行最後一個RegisterTaskDefinition步驟時遇到了80041318錯誤。我閱讀here這意味着值格式錯誤或超出範圍，也可能是pLogonTrigger的錯誤參數。我試着註釋掉pLogonTrigger的開始邊界和結束邊界代碼，但這並沒有幫助。我還將pLogonTrigger UserId和userId參數更改爲L「Josh」作爲我的帳戶的RegisterTaskDefinition函數。 pLogonTrigger剩下的唯一參數是通過put_Id和put_UserId指定的。
我應該包括任何代碼，如果這將有所幫助，如果是的話，哪些代碼？除了pLogonTrigger修改，userId mod和合成安全性的註釋以外，代碼與示例代碼非常相似。
