Why don't you want to reload?
You can look into using a partial reload or maybe using the real-time feature of the QV server (check for example
Hope this helps,
In case you are using a QV server than you can reload your application by using Qlikview server.There is option.
You can scedule the time at which you want to reload your application.
In case you are not using QV server than you can use make the Batch File and you make a schedular going in the Scedule task properties in your computer and give the time ,so that your application is reloaded.
