Constant Detail

ERROR_CANNOT_LOAD_READER

Constant

public static const ERROR_CANNOT_LOAD_READER:int = 3204

Runtime Versions:

AIR 1.0

An error was returned by the OS when trying to load the Adobe Reader or Acrobat application or one of its necessary libraries.

Note: This is not returned from HTMLLoader.pdfCapability, but it is sent as the errorID property of an ErrorEvent object dispatched when an HTMLLoader object attempts to load PDF content and the operating system returns an error. HTMLLoader.pdfCapability may return PDFCapability.STATUS_OK, because it examines only the configuration and does not attempt to load any libraries.

ERROR_INSTALLED_READER_NOT_FOUND

Constant

public static const ERROR_INSTALLED_READER_NOT_FOUND:int = 3201

Runtime Versions:

AIR 1.0

No version of Adobe Reader is detected. An HTMLLoader object cannot display PDF content.

ERROR_INSTALLED_READER_TOO_OLD

Constant

public static const ERROR_INSTALLED_READER_TOO_OLD:int = 3202

Runtime Versions:

AIR 1.0

Adobe Reader is detected, but the version is too old. An HTMLLoader object cannot display PDF content.

ERROR_PREFERRED_READER_TOO_OLD

Constant

public static const ERROR_PREFERRED_READER_TOO_OLD:int = 3203

Runtime Versions:

AIR 1.0

A sufficient version (8.1 or later) of Adobe Reader or Acrobat is detected, but the the version of Adobe Reader that is set up to handle PDF content is older than Adobe Reader or Acrobat 8.1. An HTMLLoader object cannot display PDF content.

STATUS_OK

Constant

public static const STATUS_OK:int = 0

Runtime Versions:

AIR 1.0

A sufficient version (8.1 or later) of Adobe Reader is detected and PDF content can be loaded in an HTMLLoader object.

Note: On Windows, if an earlier version of Acrobat is installed and is running on the user's system, any running version of Acrobat or Adobe Reader, 7.x or higher, is used even if a later version is installed. In this case, if the value of the pdfCapability property is PDFCapability.STATUS_OK, when an AIR application attempts to load PDF content into an HTMLLoader object, the older version of Acrobat or Adobe Reader displays an alert, without an error message displayed in the AIR runtime. If this is a possible situation for your users, consider instructing them to close Acrobat or Adobe Reader while running your application. Or consider displaying these instructions if the PDF content does not load within an acceptable amount of time.
