Switching Plugins

Internet Explorer

This section will explain how to switch between Cortona, Contact 5.1, and Contact 6.1, with just a click of the button. The way this works is by running scripts that alter your computer's registry.

contact.res:

  REGEDIT4

  [HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\MIME\Database\Content Type\model/vrml]
  "Extension"=".wrl"
  "CLSID"="{4B6E3013-6E45-11D0-9309-0020AFE05CC8}"

  [HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\MIME\Database\Content
  Type\x-world/x-vrml]
  "Extension"=".wrl"
  "CLSID"="{4B6E3013-6E45-11D0-9309-0020AFE05CC8}"

  [HKEY_LOCAL_MACHINE\Software\Microsoft\Java VM]
  "Classpath"="C:\\PROGRAM FILES\\BLAXXUN CONTACT\\cc3deai.zip; all on one line
  C:\\PROGRA~1\\COMMON~1\\PARALL~1\\CORTONA\\corteai.zip; all on one line
  C:\\PROGRA~1\\COMMON~1\\PARALL~1\\CORTONA\\classes.zip; all on one line
  C:\\windows\\java\\classes\\;."

The first two entries of the file specify that Windows should open all .wrl files with Blaxxun Contact. The last entry sets the Java EAI classes for Contact first in the classpath of the MS JVM. The same classes can be found in the Cortona jars listed, so it is imperative that Contact's appear first. If you performed a non-standard installation of Contact or Cortona, you must check to make sure the specified files actually exist at these locations. If not, modify accordingly. You also should check to make sure you don't have other jars than listed already in your MS JVM classpath. If you do, add them to the above. Save the above to a file named blaxxun51.res, and click when you want to use Contact.

The technique for using Cortona instead of Contact is exactly the same.

cortona.res

  REGEDIT4

  [HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\MIME\Database\Content Type\model/vrml]
  "Extension"=".wrl"
  "CLSID"="{86A88967-7A20-11D2-8EDA-00600818EDB1}"

  [HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\MIME\Database\Content
  Type\x-world/x-vrml]
  "Extension"=".wrl"
  "CLSID"="{86A88967-7A20-11D2-8EDA-00600818EDB1}"

  [HKEY_LOCAL_MACHINE\Software\Microsoft\Java VM]
  "Classpath"="C:\\PROGRA~1\\COMMON~1\\PARALL~1\\CORTONA\\corteai.zip; all on one line 
  C:\\PROGRA~1\\COMMON~1\\PARALL~1\\CORTONA\\classes.zip; all on one line
  C:\\PROGRAM FILES\\BLAXXUN CONTACT\\cc3deai.zip; all on one line
  C:\\windows\\java\\classes\\;."

If you are just planning on running Cortona and Contact 5.1, then the following messages do not apply to you. In order to switch between Contact 5.1 and 6.1 you first be in "Contact mode". This means that you have most recently clicked the contact.res file above. After that, to choose 5.1, you must run the program:

To switch to 6.1, execute:

You shouldn't actually be typing this into the run prompt every time you want to switch between version. Instead, create a shortcut to each of the above files, and in their properties menu, insert the regsvr32.exe part. As before, if you have a non-standard installation of either Contact version, you must create shortcuts to the appropriate locations.
