Title Body

I would like to get the tooltip text for win32 legacy control (not WPF controls that inherently support UI Automation ). What I have done: Given a button of interest, I've got its AutomationElement , and its bounding rect I moved the mouse over this button (in code); Thread.Sleep(1500) to wait for the tooltip control to popup; Enumerate Desktop's all child windows, and get the child window tooltipAutomationElement , whose type is "Tooltip" ; From tooltipAutomationElement , get this tooltip's name property, which corresponds to the tooltip string. This actually works, but the penalty is: I have to sleep(1500) and manually wait for the tooltip to appear (5-20 buttons are to be scanned for the tooltip strings), which does not match performance requirement. What is expected (not sure if it is feasible) Programmatically get the button's tooltip string without requiring the tooltip to appear Without having to place mouse over each button one-by-one. Update 1 : For TTN_NEEDTEXT , MSDN doc seems not very clear, and I have no clue how to program this using C#. One of the relevant link for low level structures/messages related to tooltip control can be found here . Update 2 : Those who believe this could be done by ... , I would say, it is easier said than done. I welcome those who have tried, to comment on this, and some ostensibly feasible solutions are welcome if you can offer some evidence to show its applicability and effic
