check if program is running and shows a prompt

[john_zakaria]

hi everyone

now icheck if program is running or not using this code

Dim pname() As Process = Process.GetProcessesByName("AIM")
If (pname.Length = 0) Then
    MessageBox.Show("nothing")
Else
    MessageBox.Show("run")
End If

all that i need is to be sure that the program is closed before taking my action and shows for the user that the program AIM is already running. you must close it before completing (OK,Cancel)

and after pressing ok i will put my fuction

for example:
when you install the photoshop and the program is already running it shows for you that the program is already running. you must close it before completing (OK,Cancel)


and after clicking OK .. the program will compltete instalation
