>>>I have a form in my program that allows the user to enter a URL, click a button, and have the site come up in their default Internet browser. On one computer, their default browser in Netscape Communicator 4.7 (downloaded and installed last Thursday).
>>>The button is based on the _hyperlinkcommandbutton class from the _hyperlink class library found in VFP, and it is their code that is running. The registry entry HEKY_CLASSES_ROOT\http\shell\open\ddeexec\Application is checked to see what my default browser is (in this case "nsshell"). If it is not "iexplore" (which is Internet Explorer), it calls the ShellExecute API function, passing it the URL.

It appears to tie to the server designated by HKEY_CLASSES_ROOT\HTTP\shell\open\ddeexec\Application, so that even if the key HKEY_CLASSES_ROOT\HTTP\shell\open\command points to NetScape, if it sees the DDE application pointing to IExplore, it instances InterNetExplorer.Application to service the request. Look at the code from _hyperlinkbase from _HYPERLINK.VCX for the getdefaultbrowser method for some clues. I'd check your registry to see what's down the shell\open\ddeexec\Application rabbit hole to see where it points.

The only time it uses ShellExecute() is if there's no pointer to IExplore; it instances InternetExplorer.Application if it sees that it's available to exploit from the DDE reference.

>I ran this in several ways: running it as a.prg from the Command Window, building it into an executable and running it from Command, and running the executable outside of VFP. In all cases, it brought up Netscape NAvigator and wnet to the Microsoft site, as expected. This shows that the ShellExecute API call is not the culprit.

>Has anyone else run into any proiblems using the _hyperlink class, unmodified, to open a URL when Netscape is the default browser? As I stated in my original message, the class works correctly when I run my application from source code within VFP, but insists on bringing up Internet Explorer when I run it from an executable.

>I'm going to try uninstalling Internet Explorer and see what happens, and I'm also going to create a simple executable with a text box and a command button based on the _hyperlinkcommandbutton class. I am somewhat reluctant to tinker with a Microsoft-written class library, but I may not have much choice but to do some trial-and-error work on it.
