DeviceInfo.GetPropById method

The GetPropById method of the DeviceInfo object uses a device property's ID to return its value.

Syntax

retVal = DeviceInfo.GetPropById(
  Id
)

Parameters

Id [in]

Type: WiaDeviceInfoPropertyId

Specifies the ID of the property.

Return value

Type: VARIANT

This method returns the value of the property specified by Id.

Remarks

Use this method to find the value of a device property from its ID. For a list of property IDs, see WIA Property Constant Definitions. For information about Windows Image Acquisition (WIA) properties themselves, see WIA Property Constants.

For Microsoft Visual Basic applications, add a reference to "Windows Image Acquisition 1.01 Type Library". This following constants defined in that file are valid for this method:

const DeviceID = 2
const Manufacturer = 3
const Description = 4
const Type = 5
const Port = 6
const Name = 7
const Server = 8
const RemoteDevID = 9
const UIClassID = 10

Examples

The following example demonstrates the use of the GetPropById method to retrieve a property value.

<SCRIPT LANGUAGE="VBScript">
const WIA_DIP_DEV_TYPE = 5
Dim objWia
Dim objDeviceInfoCollection
Dim objDeviceInfo
Dim PropValue
 
Set objWIA = CreateObject("Wia.Script")
 
Set objDeviceInfoCollection = objWia.Devices
 
For Each objDeviceInfo In objDeviceInfoCollection
    PropValue = objDeviceInfo.GetPropById(WIA_DIP_DEV_TYPE)
Next
</SCRIPT>
