Public Shared ReadOnly ProcessIdProperty As AutomationProperty

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent identifier in AutomationElementIdentifiers.

This property can also be retrieved from the Current or Cached properties.

Return values of the property are of type Int32. The default value for the property is 0.

The following example retrieves the current value of the property. The default value is returned if the element does not provide one.

Dim processIdentifier As Integer = _
    CInt(autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty))

The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupportedis to be returned instead of a default value.

Dim processIdentifier1 As Integer
Dim processIdentifierNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty, True)
If processIdentifierNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    processIdentifier1 = CInt(processIdentifierNoDefault)
End If
