如何检测时，插入SD卡？ [英] How can I detect when an SD card is plugged in?

问题描述

我正在写在C中的PC应用程序++，需要在用户的SD卡连接到他/她的计算机检测。我知道如何检测，当卡读卡器连接，但我不知道如何检测时，各个卡连接/移除。

I'm writing a PC application in C++ that needs to detect when a user connects an SD card to his/her computer. I know how to detect when the card reader is connected, but I do not know how to detect when individual cards are connected/removed.

Windows能否有一个IO接口检测SD卡到货/去除？

Does Windows have an IO interface to detect arrival/removal of SD cards?

[更新]的WM_DEVICECHANGE技术，建议仅适用于在SD卡读卡器插入检测，不检测，当个人卡插入读卡器。

[Update] the WM_DEVICECHANGE technique that was suggested works only for detecting when an SD Card reader is plugged in. It does not detect when individual cards are inserted into the card reader.
