Interface: ISpeechRecoGrammar
The Id property returns the ID assigned to the grammar when it was created.
Set: | Not available. |
Get: | Variant = ISpeechRecoGrammar.Id |
The following Visual Basic form code demonstrates the use of the ID and RecoContext properties. To run this code, create a form with the following controls:
Paste this code into the Declarations section of the form.
The Form_Load procedure creates a recognition context with two ISpeechRecoGrammar objects. The ISpeechRecoGrammar objects are created with ID properties of 6 and 7. The Command1 and Command2 procedures each send one of the grammar objects to the GrammarSub procedure as parameters. The GrammarSub procedure displays the ID of the grammar object parameter, and uses the parameter's RecoContext property to pause and resume the recognition context that owns the grammar.
There is no special significance to the Id property values of 6 or 7; these values are arbitrary. Additionally, the Pause and Resume methods in the GrammarSub procedure are intended simply to show how the grammar's RecoContext property provides access to the methods and properties of the recognition context which owns the grammar.
Option Explicit
Dim RecoContext As SpeechLib.SpSharedRecoContext
Dim objGR1 As SpeechLib.ISpeechRecoGrammar
Dim objGR2 As SpeechLib.ISpeechRecoGrammar
Private Sub Command1_Click()
Call GrammarSub(objGR1)
End Sub
Private Sub Command2_Click()
Call GrammarSub(objGR2)
End Sub
Private Sub Form_Load()
Set RecoContext = New SpSharedRecoContext
Set objGR1 = RecoContext.CreateGrammar(6) 'Create grammar with ID = 6
Set objGR2 = RecoContext.CreateGrammar("7") 'Create grammar with ID = 7
End Sub
Private Sub GrammarSub(G As SpeechLib.ISpeechRecoGrammar)
G.RecoContext.Pause 'Pause the RecoContext that owns grammar
MsgBox G.Id 'Display the Id
G.RecoContext.Resume 'Resume the RecoContext
End Sub
