Syntax

Visual Basic (Declaration)
Overloads Public Function Run( _ ByVal stream As Stream, _ ByVal categories As List(Of IMasterFormsCategory) _ ) As AutoFormsRunResult

Visual Basic (Usage)	Copy Code
`Dim instance As AutoFormsEngine Dim stream As Stream Dim categories As List(Of IMasterFormsCategory) Dim value As AutoFormsRunResult value = instance.Run(stream, categories)`

C#
public AutoFormsRunResult Run( Stream stream, List<IMasterFormsCategory> categories )

C++/CLI
public: AutoFormsRunResult^ Run( Stream^ stream, List<IMasterFormsCategory>^ categories )

Parameters

stream: A Stream containing the the unknown form image data.
categories: List of Master Forms categories to use in comaprison, 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 stream 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 form type has no field then AutoFormsRunResult.FormFields will be null.
