Get your feet wet with Powershell GUI

Here’s my latest attempt in creating a simple GUI using Powershell for Windows Resource Management Tasks. Powershell by itself is easy but there is hardly any documentation on the web for creating a cool GUI. You have to put together various bits and pieces by the trial and error method. Anyway I did come up with some success. However there is a lot to be desired. For some reason the results only show up when the GUI is closed through the Cancel or Exit button. Feel free to tweak the code as you please. The Windows Management Commands are some basic scripts taken from Powershell Pro.

This is the GUI I created. Do read my post Powershell GUI – Adding bells & whistles for creating a full-fledged Powershell GUI

Feel free to send me any comments.
