Visual Basic (Usage)	Copy Code
Dim instance As WiaSession Dim item As Object   instance.SetProperties(item)

public void SetProperties( 
   object item
)

public:
void SetProperties( 
   Object^ item
) 

Parameters

item

Handle to the item having its properties set. Retrieve this parameter by either calling the WiaSession.GetRootItem method to get the device’s root item or by enumerating the child items of the device through a call to the EnumChildItems method.

Call this method after passing a valid WiaProperties structure to the WiaSession.Properties property to set those properties for the WIA device’s item passed through the item parameter.

Add the SetPropertiesEvent event to be informed of any error codes returned from setting each property available in the WiaProperties structure, and to have the ability to cancel the process.

Note:

If the ShowUserInterface flag is set for any of the acquire methods, then be aware that some of the previously set/changed user properties (using any of the SetPropertyXxx or SetProperties methods) will be overwritten by the Microsoft's image acquisition dialog box. Microsoft's image acquisition dialog box sets its own initialization properties like the current intent (image type), selected area (left, top, width and height), paper source and duplex mode, ...etc. To suppress the manufacturer’s image acquisition dialog and acquire directly from the specified source item through the item parameter using the values set through the SetPropertyXxx and SetProperties methods, do not set the ShowUserInterface flag.
