Par2: Autospot Hyperlinks without displaying the URL
1998-08-03 -- Jim DeFabia
 
Internet Connect's Autospot Hyperlinks feature displays something like http://mydomain.com/mypage.htm. To display some text instead of the URL, there is a feature of the Clarion Java Applet that will allow you to do this. The Java string control and the Java list controls have built-in capabilities to do exactly that determine the display based on the data it is called upon to display. If the data contains a string that is formatted in a special manner, it displays some text and links to a URL. To work in this manner, the data must contain a valid URL followed by the display text. The text to be display must be enclosed in angle brackets (< >). For example http://www.topspeed.com will display "Visit the TopSpeed Web Site" while a click on the control will send the user to www.topspeed.com. You can use this feature in a number of ways. Of course, you can have a data field which contains data formatted exactly as you want it, but that requires users to know how to enter the data. A better way is to use two fields -- one for the URL and the other for the display text. Then concatenate a string for the Java String control to use. For example: LOC:URLLink = FIL:URL & '<<' & CLIP(FIL:URLDisplayText) & '>' Notice that the left angle bracket (<) is duplicated. This is required to handle this special character. You can also use this technique for a filed displayed in a BrowseBox control. Just populate the local variable and create a formula similar to the one above to assign its value. One caveat: The opening angle bracket must adjoin the URL; there can be no spaces in between.
