How to Launch or Close the Process by using QTP
There are many ways to close the process as of now we will deal with SystemUtil
SystemUtil Object
QTP Provided many utility object one of them is SystemUtil.It can be used to for launching or closes a process. We will look in  various operations supported by this object:
SystemUtil.Run ( Filename, Parameters, Path, Operation )

Ø  Filename: The name of the file which we want to run.
Ø  Parameters: If the specified Filename is an executable file, use the Parameters argument to specify any parameters which need to be passed into the application.
Ø  Path: The default directory of the application or file.
Ø  Operation: The action to be performed. If this argument is blank (""), the open operation is performed.
The following operations can be specified for the operation argument of the SystemUtil.Run method:
The Run method allows running a new process. The code below illustrates few example on how to launching a process using SystemUtil object
'@@@@@@For run chrome explorer
SystemUtil.Run "chrome.exe"
'For run internet explorer
SystemUtil.Run "firefox.exe"
'@@@@@@For run internet explorer
SystemUtil.Run "iexplore.exe"

'@@@@@@Run a IE Process in Maximized window
const show_maximized = 5 'I will activates the window and displays it as a maximized window.
SystemUtil.Run "iexplore.exe", "", , , SHOW_MAXIMIZED

SystemUtil.CloseProcessByName (bsProcessName)
“CloseProcessByName” is a method will allows closing a process by its name.
'@@@@@@Close all internet explorer windows
closedCount = SystemUtil.CloseProcessByName("iexplore.exe")
