• Do I need to check capacity before adding an element to a vector in c++ ?

  - by Cassie

  Hi dear all, I am a newbie to c++ STL vectors so sorry for silly questions in advence. :) In my program, I have a vector which needs to store unknown number of elements. Do I have to check if the vector has achieved its max_size before adding an new element to it ? Will a c++ compiler throw an exception automatically when a program tries to add elements to a full vector ? Thank you very much, Cassie

• jquery multiple ajax check for all done? (order not important)

  - by second

  Is there a neat way to make sure a bunch of ajax callbacks have all finished? They don't need to be executed in order, i just need all the data to be there. one idea is to have them all increment a counter on completion and check if counter == countMax, but that seems ugly. Also, are there sync issues? (from simultaneous read/write to the counter)

• How to check if user submit Arabic words from a form?

  - by ronanray

  Hi Experts.. Is there any reliable way to check if user has entered Arabic words into a form and tries to submit it? Can Javascript handle this? Or, only server script like .NET can do this? I'm thinking that if possible the script should directly prevent the user from inputting Arabic words into the form and show an alert pop up. Please share any examples if you have any idea how to do it. Thanks

  Given a file, I want to check if this is a DLL, or a shared object (Linux) or a dylib (Mac OS X), or something different. My main interest is differentiating executable and DLL on Linux and Mac OS X. For windows, the extension should be enough for my problem.

• Algorithm: how to check intersections of recurring events definitions?

  - by glaz666

  The question comes from MS Outlook calendar behavior. Imagine I have two recurring events (starting from today): "each second Monday" and "every odd date". Is there any way to check intersections and/or find the first intersecting date algorithmically without brute-forcing over each date? Definitions can be made in CRON's notations or ICal notation. I think it doesn't matter. Are there any solutions for this in Gregorian calendar?
