What would be the possible way to detect the insertion and removal of other USB peripherals, such as mouse and keyboard?
I am having problem with my FYP that my application is based on the detection of Insertion and Removal of a device. I am aware that this would happen using Win32_VolumeChangeEvent class or WMI. (Please notify me if I am wrong). Kindly solve this problem and send the code for Console Application in VB.NET. Please do not send code in any script language or C#. Also to get the device information.
View 6 Repliesscardgetstatuschange DOES wait(timeout is set INFINITE by -1) for card-insertion after connecting the reader-device to the pc. After a card is being insterted the first time and removed again, it won't wait any longer and returns immediately everytime;
lResult = SCardGetStatusChange(DethContext, -1, rgReaderState(0), 1)
So, scardgetstatuschange CAN work. But why only when i re-attach the cardreader-device to the pc????
I know you can do it with an WMI event or overriding WndProc and looking for the right messages, but i was wondering if there wasn't something hidden in the net framework that makes this task easyer.

Rejecting it would prevent its being loaded by Windows. I have the code that detects insertion & removal working fine but have no idea how to cancel the insertion.I was thinking that I could intercept the DEVICEARRIVAL message and kill it off before its actioned by Windows but I am lost with this.code to show the way.Heres the main part of the code I have so far-

View 2 RepliesI am creating a DIY calculator.The one in W7, I can't hardly see. Mine is much simpler and larger.I currently have buttons for numeric 0 - 9, Add, Subtract, Multiply, Divide, Clear, Enter, and Decimal Point.There is a label at the top with displays results.If I use my mouse to select the buttons, then everything works okay. However, if I use the keyboard, I get strange results.I thought it may have been my old keyboard so I changed it.No difference.If it's not in the hardware, then it's in the code.The section below is what I have for keyboard use:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Ch = e.KeyChar
Select Case Ch[code]....
For each of these, there is a corresponding Button_Click even farther down in the code. Since the mouse click on the buttons on the form works properly, the problem must be above. I can't see it.

I am a newbie to this forum. I searched across a lot to find a way in VB.net how to capture the keyboard and mouse events scoping to the whole computer.

View 3 RepliesI am kind of amazed that there is no answer to this anywhere and I mean anywhere. I am looking for a way to disable the keyboard (actually all input) on a computer. There are several threads about it but no one has ever posted any serious, working code. I know someone is going to inevitably ask "why would you want to do that"? Actually why I want to do it is immaterial but if you must know... I am playing with a "USB Keylock". When this USB Keylock is not present in the computer I want to disable the keyboard. When it is present I want to enable the keyboard.
