When the URL is not a fully qualified path, SEARCH and LOAD-IMAGE( ) do not raise an error and searching continues with the next entry in the PROPATH.
When the URL is a fully qualified path:
The SEARCH function does not raise an error but returns the Unknown value (?).
The LOAD-IMAGE( ), LOAD-IMAGE-DOWN( ), LOAD-IMAGE-UP( ), LOAD-IMAGE-INSENSITIVE( ), and LOAD-ICON( ) methods all raise error 9368, where server-name is the host name of the Web server, as shown:
|
Unable to download file from the web. Authentication failed for server server-name.

You can trap this error, request a user ID and password, and try to download the image again, as in the following example:
|
DEFINE BUTTON Button1.
Button1:LOAD-IMAGE ("http://userid:password@www.progress.com/myimage.jpg") NO-ERROR. IF ERROR-STATUS:GET-NUMBER(1) = 9368 THEN DO: /* Display dialog. */ /* Update URL string. */ /* Retry load-image. */ END. |
