Routine Description:
Invokes an external program, which is optionally detached.
Arguments:
ApplicationName - supplies app name. May be a partial or full path,
or just a filename, in which case the standard win32 path search
is performed. If not specified then the first element in
CommandLine must specify the binary to execute.
CommandLine - supplies the command line to be passed to the
application.
ExitCode - If specified, the execution is synchronous and this value
receives the exit code of the application. If not specified,
the execution is asynchronous.
Timeout - specifies how long to wait for the app to complete.
Hidden - if TRUE, indicates that the application should be invoked with
the SW_HIDE attribute set.
Return Value:
Boolean value indicating whether the process was started successfully.
