Hello everyone, i have been looking all day for a way for my application to 'safely remove hardware' or to eject the USB key specified, the application detects the removal and arrival of new devices but i am stuck on being able to eject them. So far my research has lead me to using setupapi.dll and CM_Request_Device_Eject and i have declared
I usully code in asp for web application and have no idea how to use these types of unmanaged functions
I made my function that takes the drive letter to eject by parameter
I found pinvoke.net: cm_request_device_eject (setupapi) this info on pinvoke for CM_Request_Device_Eject() but i am clueless on how it works and the vb.net section looks prolly documented...anyways if anyone can help me with a code snipet or just guide me in the right direction it would be very appreciated.
Thx
Alex
VB.NET:
Private Declare Function CM_Request_Device_Eject Lib "setupapi.dll" Alias "CM_Request_Device_EjectW" (ByVal dnDevInst As IntPtr, _ ByRef pVetoType As PNP_VETO_TYPE, ByVal pszVetoName As IntPtr,ByVal ulNameLength As Integer, ByVal ulFlags As Integer) As Integer
I usully code in asp for web application and have no idea how to use these types of unmanaged functions
I made my function that takes the drive letter to eject by parameter
VB.NET:
Public Function EjectDevice(USBDriveLetter as string) As Integer
'TODO USE CM_Request_Device_Eject() to eject the drive
End Function
I found pinvoke.net: cm_request_device_eject (setupapi) this info on pinvoke for CM_Request_Device_Eject() but i am clueless on how it works and the vb.net section looks prolly documented...anyways if anyone can help me with a code snipet or just guide me in the right direction it would be very appreciated.
