Syntax
C#
VB
C++
  
Public Overloads Function Run( _ 
   ByVal fileName As String, _ 
   ByVal categories As List(Of IMasterFormsCategory) _ 
) As AutoFormsRunResult 
public: 
AutoFormsRunResult^ Run(  
   String^ fileName, 
   List<IMasterFormsCategory^>^ categories 
)  

Parameters

fileName
A System.String containing the name of the unknown form image file.

categories
List of Master Forms categories to use in comparison, pass null or empty to use all Master Forms in the repository.

Return Value

Returns the results of the recognition and processing if the form is recognized, otherwise it returns null. If the Master Form has no processing field, AutoFormsRunResult.FormFields will be null.

Remarks

This method automatically recognizes the unknown form and process its fields at the same time.

The fileName should have all form pages.

If RecognizeFirstPageOnly is true, the recognition will be performed based on the first page only, if it is false the recognition will be performed over all the form pages.

If the form is not recognized it will return null, if the Master Form of the fileName type has no field then AutoFormsRunResult.FormFields will be null.
