I don't actually need this code at the moment, but I thought I'd report the following observation:

While looking at the IE Custom control package, I noticed the Mozilla version as well. When I try to compile the Mozilla control package, I get the following warning:

C:\Documents and Settings\John\My Documents\Visual Prolog 7.0 Examples\testMozillaCtrl7\testMozillaCtrl\inteface\testForm.pro(89,5) : warning c654: Unused local predicate 'testForm::onEditLoseFocus/1 (i)'
C:\Documents and Settings\John\My Documents\Visual Prolog 7.0 Examples\testMozillaCtrl7\testMozillaCtrl\inteface\testForm.pro(91,5) : See also


When I then try to run the example from the menu the program terminates with the following dump (I'm using 7004 CE):

Seems that you have not installed the Mozilla ActiveX component or it is not registered orderly. Or maybe you have a newer Mozilla ActiveX component than I used when making the example (if I remember correct it was version 1.5 and now the newest seems to be 1.7.12).

I don't think that "version difference" will give this kind of problem.

Normally, never versions of "something" implements the "old" components (maybe plus some new ones). Otherwise, upgrading "something" would break other applications.

The other applications may of course change behavior anyway when some component is upgraded and in worst case they may indeed break. But it is not normal that they break by "Class not registered".

Notice that a COM component class may have some nice human sensible name, but the real "name" is its id: This is the "name" that is used when trying to locate it on the computer.

This ID is looked-up in the registry, the registry tells which file to load in order to get and instance of the component class. And this file can be version x or version y.

Hi,

Where can I found this sample : testMozillaCtrl7 ?
