Windows驅動程序：PreOperationCallback不叫

我正在嘗試使用Microsoft示例（PassThough，minispy ...）創建基本的微過濾器驅動程序，但未調用MfPreOperationCallback。我嘗試了不同的上下文（即使我不確定如何理解它是如何工作的......）。我試圖直通例子，它工作得很好，這是非常相似，我的代碼...Windows驅動程序：PreOperationCallback不叫

有誰看到這是怎麼回事？

你的驅動加載？ FltRegisterFilter可以嗎？哪裏錯誤？ '有人看到發生了什麼事 - 但你呢？你看到了嗎？試着看？ – RbMm

我沒有錯誤，是的，我的過濾器被加載，我沒有得到一個關於startfiltering函數的錯誤代碼，所以我想它正在過濾......但是kdprint沒有在我的預操作函數中調用，所以我想這個函數回調沒有被調用...（我通過創建一個文件來測試我的驅動程序，PassThrough示例對此事件作出反應，但不是我的過濾器！） – guidono

MfInstanceSetup被調用？什麼Windows版本？ – RbMm

我解決了我的問題：我在我的inf文件中有錯誤的標誌。好的一個是0x0標誌，以便將微濾器自動連接到不同的捲上。

Instance1.Flags = 0x1 ; Suppress automatic attachments

到

Instance1.Flags = 0x0 ; Automatic attachments
