  • Maximum number of concurrent users connected to SQL Server 2008

    - by worlds-apart89
    Is there a limit to the maximum number of concurrent users connected to SQL Server 2008? I am guessing computer resources determine that limit (if it exists), but I am also wondering if there is a theoretical limit. I have tried googling the answer, but all the information I have found is based upon earlier versions of SQL Server. If there is a limit, does it apply to just a database or a SQL Server instance?

  • Enable/Disable WPF buttons depending on the number of clicks

    - by eibhrum
    I have two buttons 'btnPrev' and 'btnNext' What I want to do is to be able to determine the number of clicks of the button so that I could enable and disable them. The process is almost similar to 'paging' method. Initial state: btnPrev - disabled, btnNext - enabled 1st Click (btnNext): btnPrev - enabled, btnNext - enabled 2nd Click (btnNext): btnPrev - enabled, btnNext - enabled 3rd Click (btnNext): btnPrev - enabled, btnNext - disabled the idea is almost the same vice-versa (for btnPrev).

  • Count number of arguments to Excel formula in VBA

    - by Abiel
    I need to use VBA to determine the number of arguments passed to an Excel formula. For instance, suppose a cell contains the formula =MyFunc($A$1, "xyz", SUM(1,2,COUNT(C1:C12)), IF(B12,1,0)). Then the counter function should return 4. Does VBA contain any built-in functions for this, or does someone have an example of a regular expression that could calculate this?

  • Number of threads and thread numbers in Grand Central Dispatch

    - by raphgott
    I am using C and Grand Central Dispatch to parallelize some heavy computations. How can I get the number of threads used by GCD? Also is it possible to know on which thread a piece of code is currently running on? Basically I'd like to use sprng (parallel random numbers) with multiple streams and for that I need to know what stream id to use (and therefore what thread is being used).

    - by Gavin
    I'm trying to get a very simple Flash video working using SWFembed, and it does work across multiple computers at this point in multiple browsers, but as soon as I pushed it live I got this: http://cl.ly/1EDS I've adjusted file permissions, but it is exactly the same code and files as in another directory on the server. I've seen this a few times (green box with version number), but have not been able to find any reference to it online. Thanks for any suggestions in advance!

  • How to calculate an IPv6 IP Number?

    - by Bram
    I'm adding GeoIP tracking to WCF Web Service using MaxMinds' GeoIP Lite Country. All works well for their IPv4 database but they don't give any samples to calculate an IPv6 IP Number. I've contacted them and they said to use a search engine. Anyone have a sample they're willing to share? Any language will do.

  • Why does typeof NaN return 'number'?

    - by KooiInc
    Just out of curiosity. It doesn't seem very logical that typeof NaN is number. Just like NaN === NaN or NaN == NaN returning false, by the way. Is this one of the peculiarities of javascript, or would there be a reason for this?
