Resolution

Published Application Manager also includes two wizards that let you create the ICA files and HTML pages you can place on your Web server for users to visit to initiate ICA sessions. After publishing an application, use the Write ICA File wizard to create an ICA file for the application.

How to Create an ICA File

The following ICA session attributes are stored in ICA files:

• The address of the Citrix server or the name of the published application definition to run
• The user name, password, and domain name to use when connecting to the Citrix server
• The encryption level to use when connecting to the Citrix server
• The size and color depth of the application window when launched from a Web page, expressed in pixels or as a percentage of the window size

NOTE: Applications embedded in Web pages are sized according to the height and width tags specified in the Web page. The size specifications in the ICA file are ignored.

To create an ICA file

1. Start Published Application Manager. (On the MetaFrame desktop, click Start, point to Programs, MetaFrame Tools, and then click Published Application Manager.)
2. In Published Application Manager's main window, select an entry in the list of published applications.
3. In the Application menu, click Write ICA File, or right-click the published application and select Write ICA File.
4. Follow the directions on screen. When prompted, save the ICA file to some location on the Web root of your Web server.

You can test ICA files on any system on which you have installed one of the ICA Windows Web Clients and that can access the Citrix server using TCP/IP. Copy the ICA file to that computer and then double-click it in File Manager or Windows Explorer.

See the online Help for Published Application Manager for more information about the Write ICA File wizard.

Modifying the ICA File to be used with a Seamless Window

You can make an ICA file that launches a seamless windows session by adding the following lines to the application section of the ICA file:

DesiredHRES=4294967295
DesiredVRES=4294967295
ScreenPercent=0
UseDefaultWinSize=Off
DesiredWinType=8
TWIMode=On

Details

Here is an example of a complete ICA file that launches the published application MyPublishedApp in a seamless windows session:

----- Begin ICA file -----

[WFClient]
Version=2
TcpBrowserAddress=10.1.2.3

[ApplicationServers]
MyPublishedApp=

[MyPublishedApp]
Address=MyPublishedApp
InitialProgram=#MyPublishedApp
Domain=DomainName
DesiredColor=2
TransportDriver=TCP/IP
WinStationDriver=ICA 3.0
DesiredHRES=4294967295
DesiredVRES=4294967295
ScreenPercent=0
UseDefaultWinSize=Off
DesiredWinType=8
TWIMode=On

----- End ICA file -----
