IWindowProvider.WaitForInputIdle Method

Causes the calling code to block for the specified time or until the associated process enters an idle state, whichever completes first.

Namespace:  System.Windows.Automation.Provider
Assembly:  UIAutomationProvider (in UIAutomationProvider.dll)

bool WaitForInputIdle(
	int milliseconds
)

Parameters

milliseconds
Type: System.Int32

The amount of time, in milliseconds, to wait for the associated process to become idle. The maximum is MaxValue.

Return Value

Type: System.Boolean
true if the window has entered the idle state; false if the timeout occurred.

ExceptionCondition
ArgumentOutOfRangeException

When the parameter passed in is not a valid number.

This method is typically used in conjunction with the handling of a WindowOpenedEvent.

The implementation is dependent on the underlying application framework; therefore this method might return some time after the window is ready for user input. The calling code should not rely on this method to ascertain exactly when the window has become idle.
