Thank you for your reply. I never new that those defines existed within the
tree.
You were correct. I thought if I had removed the toolbar from Netscape that
my XPCOM components and type libraries would be unloaded. Wrong assumption!
I get an error if I try to delete the files.
The only way I found to remove the components is to check for the existance
of them on a re-install, and if they exist - remove them. That worked fine
on the XPCOM components and type libraries, but not on the JAR (contains XUL
and JS stuff) within the chrome folder. I have to re-install the software
twice before my toolbar appears in Netscape. I believe the first time the
jar is deleted and the next time the jar is installed. The uninstall on both
attempts displays a successful result.This was not the behavior I was hoping
for - but id does get the job done in a round about fashion. This is a
little snippet of what I tried to do.
fChrome = getFolder("Chrome");
var delJarFile = getFolder(fChrome, myJarFileName);
if(File.exists(delJarFile)) // If exists from previous
installation - delete it.
{
File.remove(delJarFile);
logComment("Removing: " + delJarFile);
}
setPackageFolder(fChrome);
err = addFile(myJarFileName)
logComment("addFile() returned: " + err);
err = registerChrome(PACKAGE | DELAYED_CHROME,
getFolder(fChrome,myJarFileName), "content/");
logComment("regChrome returned: " + err);
if(err == ACCESS_DENIED)
{
alert("Unable to write to Chrome directory "+fChrome+".\n You will need to
restart the browser with administrator/root privileges to install this
software. After installing as root (or administrator), you will need to
restart the browser one more time to register the installed software.\n
After the second restart, you can go back to running the browser without
privileges!");
cancelInstall(ACCESS_DENIED);
}
else if (err != SUCCESS)
{
cancelInstall(err);
}
else
{
performInstall();
}
