Taken from https://www.citrix.com/blogs/2010/03/02/fun-with-the-ica-client-object-ico-and-net-console-applications/ The following code example illustrates the use of Client Simulation Keyboard APIs to type within our Notepad application session, take a screen shot and save it to the %temp% directory, and finally enumerate and output the top leve…
