Visual Basic (Usage)	Copy Code
Dim instance As WiaSession Dim item As Object Dim propertyIdName As String Dim propertyId As WiaPropertyId   instance.SetPropertyLong(item, propertyIdName, propertyId)

public void SetPropertyLong( 
   object item,
   string propertyIdName,
   WiaPropertyId propertyId
)

public:
void SetPropertyLong( 
   Object^ item,
   String^ propertyIdName,
   WiaPropertyId propertyId
) 

Parameters

item

Handle to the item which represents the item having the property. You can retrieve this parameter by either calling the WiaSession.GetRootItem method to get the device’s root item itself or by enumerating the child items of the device through a call to EnumChildItems method.

propertyIdName

This string should contain the equivalent property Id string for the WIA property ID. Use the see GetPropertyIdString method to get this string for the property ID.

If you passed null for this parameter then the WIA toolkit will use the property ID passed through the third parameter propertyId; otherwise this parameters will be used whether or not you passed valid property ID through the propertyId parameter

propertyId

The property ID for the value being sought, for list of available property IDs see WiaPropertyId.

This parameter is required only if the second parameter "propertyIdName"is null; otherwise you can pass 0 for this parameter.

Call this function to set the Long value for any WIA property of the types mentioned (for instance, WiaPropertyId.ScannerDeviceDocumentHandlingSelect , WiaPropertyId.DeviceInfoDevTypeWiaPropertyId.ItemBufferSize , ...etc).

Note:

Through our testing we have found that on some drivers while using WIA 2.0, if you want to change the Image Data Type property ( WiaPropertyId.ItemDatatype ) to your custom setting you have to set the WiaPropertyId.ScannerItemCurIntent property value to None.

Before calling this method make sure you pass a valid Long value to the LongValue property that represents your Long value you need to set.

For more information, refer to Managing WIA Sources.
