progress

问题 I've got a fairly simple issue I'm not sure how to resolve. I want to change the message text of a Progress Dialog while it's running and showing. An example of this would be something like a "time remaining" counter that would count down while the progress animation is spinning. I'm not sure how I would approach this because doing progressDialog.setMessage(String), even within a running thread, will not change anything in the Dialog itself. Thank you! 回答1: You might want to check this

问题 I've seen in Oracle 10g a feature that estimates the remaining time for a long running query and I was wondering if this is possible too in SQL Server (at least in 2008?)? Suppose I have a very large table with tens of millions of rows (well indexed etc. etc.) and I need to search for some particular rows. I know it will take a lot of time and I'm cool with that but I would like to present the user with some kind of a progress bar. How can I show progress? 回答1: I'd forget about it and just
