  • Reference

Definition

Namespace:
System.Windows.Automation
Assembly:
UIAutomationClient.dll

Identifies the ProcessId property.

public: static initonly System::Windows::Automation::AutomationProperty ^ ProcessIdProperty;
public static readonly System.Windows.Automation.AutomationProperty ProcessIdProperty;
 staticval mutable ProcessIdProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly ProcessIdProperty As AutomationProperty

Field Value

AutomationProperty

Examples

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

int processIdentifier = (int)
    autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty);

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, NotSupported is to be returned instead of a default value.

int processIdentifier1;
object processIdentifierNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty, true);
if (processIdentifierNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    processIdentifier1 = (int)processIdentifierNoDefault;
}

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
