• How do I prevent users from entering a blank value in an Excel sheet?

  - by Tola Odejayi

  I want to restrict users to entering either just 0 or 1 in an Excel 2007 sheet. I use the Data Data Validation dialog to do this, but I'm finding that it doesn't stop them from entering blanks. What I would like is for there to be a prompt when they enter blanks, just like the one that appears when they enter any other non-blank data that is not 0 or 1. I plan to fill the sheet with 0s before applying the validation, so there should not be a problem with erroneous data. Also, I'm open to using VBA to fix this problem.

• Any Microsoft SQL Server 2008 licensing restrictions on usage?

  - by ryrobes

  Does Microsoft have any problems with HOW I USE SQL Server Standard Edition 2008? I plan on using it to aggregate my clients various data sources and report on them (using the whole stack - SSIS, DB, Analysis Services and Reporting Services) via the web. I don't want to run into any issues with being accused of "re-selling" services / features when I'm not allowed to, etc. In essence, I'm charging people to build them solutions based on / using MY licensed copy and then giving them access to the final products. (reports, etc) It seems straightforward enough - but who knows with MS... (BTW, Licensed by processor / not CAL)

• What is a good metaphor for c memory management?

  - by fsmc

  I'm trying to find a good metaphor to explain memory allocation, initialization and freeing in c to a non technical audience. I've heard pass-by-reference/value talked about quite well with postal service usage, but not so much for allocation/deallocation. So for I've thought about using the idea of renting a space might work, but I wonder if the SO crew can provide something better.

  Could someone please explain what an I/O Error 32 refers to in the context of a network socket? I have a multithreaded Socks5 server written using Poco SocketReactors and am getting this error when the server load reaches a certain point. The exception is thrown within my onReadable handlers at the same time across all threads which have connections associated with them. The only other thing I am doing within those threads is std::cout but I am not sure if this is a potential cause.

  - by Jimbo

  I have a class (Class B) that inherits another class (Class A) that contains virtual methods. Mistakenly, I omitted the override keyword when declaring a (supposed to be) overriding method in Class B.

• named anchors not working in safari

  - by David

  Hi there, can anyone explain why named anchor tags would not work in safari but work fine in other browsers: ie, ff, opera, chrome. I have some links to different areas of the same page and nothing happens when clicking on them in safari only. All the other browsers mentioned take me to that area of the page. I have tried using both the id and the name attribute for the anchors but neither makes any difference.

• HP MSA 1000 SAN: Can I use 1 array/shelf?

  - by CC

  Hi all, I'm planning some expansion on an HP MSA1000 SAN. My boss says that we need to have two separate arrays on the new enclosure, one for Bays 1-7, the other for Bays 8-14. Is there any reason that we need to do this? My plan was to have the entire expansion shelf be 1 array, then create RAID 6 logical drives from that. I don't understand what splitting drives into separate arrays gain us. We don't have dual controllers, so there's no benefit there. Thanks, CC

• Why 10675199.02:48:05.4775807 TimeSpan Maximum for CompilationSection?

  - by Alex

  I was looking at the metadata for System.Web.Configuration.CompilationSection, and noticed the following attribute on the TimeSpan BatchTimeout property: [TimeSpanValidator(MinValueString = "00:00:00", MaxValueString = "10675199.02:48:05.4775807")] Could someone explain why this is the allowed max value? TimeSpan itself has an upper limit, so why would there be another value validation, and why this number?
