How to show/hide another application's window(s)?

Question

I want to create a button that can hide an exe application. As example: this application will start spider.exe when page loads. I need a button that can hide & show the spider.exe. How can I do it with VB.NET, C#, or Java?

I tried to use

myProcess.StartInfo.WindowStyle =  System.Diagnostics.ProcessWindowStyle.Normal
myProcess.Start()

in page load part, and use

myProcess.StartInfo.WindowStyle =  System.Diagnostics.ProcessWindowStyle.Hidden

in button part but it does not work

Process.StartInfo.WindowStyle only affects the properties of the process when it starts, it has no effect after the processes has started. — shf301, Jun 06 '11 at 11:34

I think you should use PInvoke and call API ShowWindow passing the other app window handle and proper parameters to show or hide.
