Core Function ProcessExists

Revision as of 12:38, 14 June 2015

ProcessExists( <pid/name> )

Description

Checks to see if a specified process exists.

Parameters

pid/name

The name or PID of the process to check.

Return Value

Success: Returns the PID of the process.

Failure: Returns 0 if process does not exist.

Remarks

Process names are executables without the full path, e.g., "notepad.exe" or "winword.exe"

If multiple processes have the same name, the one with the highest PID is returned--regardless of how recently the process was spawned.

PID is the unique number which identifies a Process.

Example

If ($PID = ProcessExists("notepad.exe"))
{
    MsgBox("Notepad is running and its PID is '$PID'");
}
else
{
    MsgBox("Notepad not is running.");
}
