IUploadFile in Upload component

Is there an easy way to make sure the user has actually chosen a file 
to upload when they click the upload button in the Upload component?

I checked to see if the IUploadFile was null, but that didn't work. Is 
there anything that will be null for sure only if there was no file 
selected?

Thanks,
Todd

I check the following:
if(IUploadFile!=null && IUploadFile.getFileName().length()>0)
   //file was selected
else
  // no file was selected

This works for me.

Cheers,

Cesar
