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

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

public:
void SetPropertyBuffer( 
   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.

Since there is no Read/Write buffer property of type WiaVariableTypes.UI1 or WiaVariableTypes.Vector until now, then we can't provide a sample for the SetPropertyBuffer method.

Any WIA property of type WiaVariableTypes.UI1 or WiaVariableTypes.Vector that is not Read only can be set by calling this method.

Before calling this method make sure you pass valid Stream to the BufferValue property that represents your buffer you need to set.

For more information, refer to Managing WIA Sources.
