Parameters

item

Handle to the item which represents the item having the property. You can retrieve this parameter by either calling the 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.

value

The WIA buffer value to set.

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

For more information, refer to Managing WIA Sources.

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.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
