  • Hello,


    This is going to change sometime next week when we release a Firefox version.  In the meantime if you want to get your page tested, I recommend just copying the following function out of our Javascript example and using it.  Unfortunately you can't call ours directly because it is buried in the hdvHost object.  We should probably change our javascript so that you can just call this directly.  Also the script snippet below is IE specific.


     function isHDViewInstalled()
      var installed = false;
       var hdvCntrl = new ActiveXObject("Viewer.ViewCtl");
       installed = true;  
      catch (e) {}
      return installed;

  • This is a bit cleaner in the new javascript.  You can now do:


    hdvHelper.isHDViewInstalled()   // to determine if HDView is installed on the system


    hdvHelper.isPlatformSupported()  // to determine is HDView is supported on the current platform/browser
