HTML Executable ebooks and publication apps have support for some command line arguments: if you want to call your publication from a third-party application and display a specific page for instance, or just run it using the Start|Run option of Windows.

The following command line switches are supported: page, mapid, setproxy, ignoreuserpos, and deactivate. But you can add your own switches too thanks to HEScript: see below.

Command line is especially useful with the "Only one instance of the publication" option (available in [Security -> Global Protection](security)). For instance:

Ø if you launch your publication again with different command line arguments, the second and subsequent invocation of the EXE doesn't start a new instance, but uses the one that's already running and only changes the page displayed in it according to the command line.

Øif you create an HTML exe application myapp.exe, you can get myapp.exe to start with a certain page by using `myapp.exe mapid 1024` where 1024 is the mapid for the page you want. If you then call `myapp.exe mapid 1025` the first instance of the app will show the page with mapid 1025.

page

Syntax:

PUBFILE.EXE page [page to display]

Use this switch to specify the virtual path to the HTML page that should be displayed by the publication.

Examples:

MYPUBFILE.EXE page comments.htm

PUBFILE.EXE page "my path page1.htm"

When you have spaces, be sure to enclose the path in quotes ("").

mapid

Syntax:

PUBFILE.EXE mapid [map ID of the page to display]

This switch can be used only if a map file is created. Specify the Map ID (integer) of the page you want to display.

Example:

MYPUBFILE.EXE mapid 1014

deactivate

Syntax:

PUBFILE.EXE deactivate

Only recognized if you enable deactivation for a certificate which lets the end user uninstall their registration data.

setproxy

Syntax: PUBFILE.EXE setproxy Lets the end user change his proxy server for activation, deactivation or validation.

ignoreuserpos

Syntax:

PUBFILE.EXE ignoreuserpos

Normally, the end user can set size and move the publication window around. For greater comfort, the publication stores those parameters for the next time it is run. However, some users will move the window to a second monitor and, for the next running, will forget the window was on this second monitor (for instance, the latter is turned off...), so it will be considered as "lost" for them.

This command line option will open the publication screen-centered, ignoring the position previously saved. Thus, the window will be accessible.

add your own switches

If you work with HEScript, it is possible to read the parameters passed to the publication .exe file when the latter is run.

You can do this using the ParamStr internal function.
