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
