			SystemTrayMessage.exe,  Version 1.06
```

			Display an icon in the system tray's notification area

```
 
```

			Usage:    SystemTrayMessage.exe  [ message ]  [ options ]

```
 
```

			Where:    message     is the message text in the optional tooltip balloon

```
 
```

			Options:  /I:icon     tooltip Icon (Error, Info, None, Warning; default: Info)

			          /L          treat message as Literal text without interpreting

			                      escaped characters, e.g. show "\n" as literal "\n"

			                      instead of interpreting it as a newline character

			          /P:path     Path to an icon file or library (default: Shell32.dll)

			          /S:index    System tray icon index in icon library (default: 277)

			          /T:title    specifies the optional Title in the tooltip balloon

			          /V:seconds  specifies the number of seconds the tooltip balloon

			                      will remain Visible (default: 10)

			          /W          Wait for the timeout to elapse or for the user to click

			                      the message, then remove the icon from the notification

			                      area (default: exit without waiting)

```
 
```

			Notes:    If no tooltip message is specified, switches /I, /L and /T will be

			          ignored and no tooltip will be shown.

			          By default, \n is interpreted as newline and \t as tab in message;

			          in some cases this may lead to misinterpretations, e.g. when showing

			          a path like "c:\temp"; either escape backslashes in paths or use /L

			          to treat all message text as literal text.

			          Command line switch /S will be ignored if switch /P specifies

			          anything but an icon library.

			          Use my Shell32Icons.exe to select a Shell32 icon and get its index.

			          Return code ("ErrorLevel") is -1 in case of errors; with /W switch,

			          return code is 2 if message balloon is clicked, or 3 if the timeout

			          expired without clicking; otherwise return code is 0.
