Public Shared Function GetCategoryGuid( _

Parameters

The WIA 2.0 item category ID. For a list of available categories refer to WiaCategories.

Return Value

The relevant System.Guid value for the category Id passed as parameter for the GetCategoryGuid method.

Remarks

This method is only used when using WIA version 2.0. Each WIA 2.0 item has a category represented as System.Guid structure that can be retrieved by calling the GetPropertyGuid method, and passing WiaPropertyId.ItemCategory for the propertyId parameter of this method. To determine the relevant category for returned System.Guid, call the GetCategoryGuid method for each available category in the WiaCategories enumeration and then compare the returned System.Guid value with this one.

Example

For an example, refer to WiaSession.GetPropertyGuid.
