Question

I have an app that is already running – every now and then it triggers a FlashWindowEx event (the windows 7 icon flashes). I would like to capture this event but I can’t seem to find any good info on how.

My thoughts were that it would go like this:

• Hook into running process using Process.GetProcessesByName
• Set up event handler for FlashWindowEx
• Catch it and do whatever

I guess my question is:

Is this possible?

1. Is there a way to get a list of available events from a running process?
2. How would I hook into FlashWindowEx?

Answer 1

The WH_SHELL hook notifies you when a window is flashing. According to the documentation:

• nCode = HSHELL_REDRAW
• wParam = the handle of the window
• lParam = TRUE if the window is flashing, FALSE otherwise.
