How do i create a routine that would constantly run in the background?

I am making a primitive database in Excel and need a routine to run in the background constantly. I will be able to fill in 开发者_开发技巧the actual actions it needs to do, but I don't know how to make something run independent of a key press or some sort of Macro. If someone can give me an example of code that runs independently which I can simply fill with contents, that would be much appreciated.

I haven't worked with VBA for quite some time now, but you would have to create a thread in VBA, maybe by COM-Threading, but I am not too sure if Excel is threadsafe or if you even can use Threads of some kind in Excel. Another alternative would be a Timer. If it is not implemented in VBA and I don't remember it to be, you would have to create the Timer yourself and react to the Windows Message yourself, if you can do that in VBA.

All in all I think this uses case might be to big for an Excel VBA Macro. If I were you I would consider doing this in a different way.
