检测到USB时执行一些操作C# [英] perform some action when usb is detected c#

问题描述

我一直在开发应用程序，现在我想检测USB设备(大量存储)，但是我需要做的是捕获该消息并将其不传递给Windows.我想问一个密码，如果还可以的话，我想将消息传递给Windows，否则将其丢弃，我该如何做到这一点，>

I have been developing an application and i want to detect usb devices(MASS STORAGE) now that i have done but what i need to do is to capture that message and dont pass it to the windows. i want to ask a password and if that''s ok then i want to pass the message to the windows otherwise discard it,,,how can i accomplish that,,,>

protected override void WndProc(ref Message m)
{
switch(m.Msg)
{
case Win32.WM_DEVICECHANGE: OnDeviceChange(ref m); break;
}
base.WndProc (ref m);
}

void OnDeviceChange(ref Message msg)
{
int wParam = (int)msg.WParam;
if (wParam == Win32.DBT_DEVICEARRIVAL)
{
    label1.Text = "Arrival";
    //MessageBox.Show("" + wParam);
    //msg = Message.Create(new IntPtr(),1,new IntPtr(),new IntPtr());
}
else if (wParam == Win32.DBT_DEVICEREMOVECOMPLETE) label1.Text =
 "Remove";
}

推荐答案

如果要阻止所有USB设备(大容量存储)，请阅读此解决方案.

禁用/启用USB阻止后重新扫描USB设备-通过注册表 [使用C#开发USB存储设备保护工具 [ ^ ]

另一种方法是将应用程序锁定在DeviceArrival，读取连接设备的VID/PID，将其阻止，要求输入密码，如果密码正确，则将其取消阻止.

希望有帮助.

Hi,

if you want to block all usb devices (mass storage), please read this solution.

Re-Scanning USB Devices after disabling/enabling USB-Block-By-Registry[^]

CP-Article:
Developing a USB Storage Device Protection Tool with C#[^]

Another way could be to lock your application at DeviceArrival, read the VID/PID of attached device, block it, ask for password and if it''s correct, unblock it.

Hope that helps.

Regards
