Many applications accept "command line parameters". Although both RDP and ICA clients
are capable of delivering these parameters to the target application, there are a few differences.
ICA Client is limited to:

• 230 character strings when accessing published applications
• 239 characters when launched application was predefined on the client

RDP client is limited to:

• 240 characters when launched application was predefined on the client
• One thing to remember - the overall limit is imposed by the NT command shell: 8178 characters

Passing parameter to Citrix published application:
First, it is important to publish application with a "%*" switch. Limiting application accessibility to "published applications only" will prevent explicit application launch based on the client configuration.
Parameters can be imbedded in ICA files or dynamically generated via custom applications or by customizing WI (Web Interface) available with MetaFrame Presentation server.

As example, here is ICA-file snapshot:

[WFClient]
Version=2
TcpBrowserAddress={BROWSERADDRESS}

[ApplicationServers]
{PUBLISHEDAPP}= [{PUBLISHEDAPP}]
Address={PUBLISHEDAPP}
InitialProgram=#"{PUBLISHEDAPP}" {PARAMETERS}
ClientAudio=On
AudioBandwidthLimit=2
Compress=On
TWIMode=No
DesiredHRES=640
DesiredVRES=480
DesiredColor=2
TransportDriver=TCP/IP
WinStationDriver=ICA 3.0
ScreenPercent=0

Here the name of the published application should be in place of {PUBLISHEDAPP} and {PUBLISHEDAPP} are replaced with command line values to be passed to the application.  To troubleshoot parameter passing one can use application "Bouncer.exe" available from Downloads section of this site. This application outputs command line parameters it receives along with the length of the incoming string.




There are a few whitepapers that address application publishing available from Citrix. A notable one troubleshoots content redirection:

ChkLat.exe: Simple tool for checking ICA session latency from within the session.

Compatibility:
Runs within ICA sessions. Compatible with Citri MetaFrame 1.8 and up, including Presentation Server 4.5.
Developed on Windows 2000, however it should be compatible with Terminal Server as well.

Note:
RDP sessions and pure Terminal Services environment is not supported, i.e. Citrix environment is required.

As you all know, RDP-listener defaults to port 3389, while ICA-listener is set to 1494. There is a convenient Citrix tool that allows port reset, change as well as query default listener - ICAPORT.EXE. Unfortunately this tool is limited to the local machine and does not list custom ICA ports in case multiple ICA-listener ports are configured.

Note, that this tool does port enumeration with determination of the current(!) default listener which is not necessarily 1494 for ICA or 3389 for RDP. This application does not test the "health" of the port. Also, it does not provide mechanisms for adding, changing or removing listener ports.

Functionality:
Launches application according to provided credentials.
Will load user profile if available.
Designed to launch executables, but can also run batch files and open documents

Examples:
Try launching MS Outlook or another e-mail program that has user specific settings
Launch Internet Explorer - you will get shortcuts, Desktop and Favorites from impersonated account
Use with CMD.EXE or Explorer.exe -- get access to resources otherwise prohibited to host user
Guest identity can be checked with Task Manager
Use within ICA or RDP session -- session identity will not change, but process started will be run within the scope of another user.

Compatibility:
Win2K and WinXP

Note:
Application is self-contained, i.e. no installation required
Some applications might display interesting behaviors. For example Citrix Program Neighborhood.
Keep this tool away from your users

Here is some help:
Utility "iPrintSearch" that lists all (not just shared!) printers o­n the server of choice.
Administrative rights are required, however this "deficiency" is eliminated with this program release as part of our of iShadow application.
You can view printer information o­n the screen, or print a report for all printers bound to particular server.



Program is self-contained and doesn't require installation. Although this tool targets Citrix MetaFrame,
it is compatible with Windows 2003, Windows 2000, Windows XP and Windows NT 4.0 including Terminal Server Edition.
Latest service packs are recommended but not required (sp3 or higher for Windows NT 4.0 is expected).

Note: ICA or RDP session environment is supported but not essential.
