When click on the button will perform a series of lengthy operations, most is to query the database and display content
Such as the three grid

Click the button to refresh a due to refresh the triggered refresh b b refresh triggered c refresh

The three refresh are asynchronous is not blocking the interface that is to say, the user can click on the button again and then continue to refresh

In order to solve the problem of refresh many times I've created a form of the size of the transparent panel on top

My code up a function in the creation process in the form of a call every time refresh

Three times but will create a panel is not accidental but not what I want

Ideal should be to have a similar thread pool as the object of management panel,

Register with each operation with a thread pool thread

When all of the threads at the end of the delete panel but helpless technology very vegetables, every brother please help
