  • Getting max. screen resolution with Group By

    - by Quandary
    Question: I have a website where I gather browser statistics. I have an SQL table (T_Visits), with the following columns: uniqueidentifier Visit_UID, uniqueidentifier User_UID, datetime Visit_DateTime, float Screen_w, float Screen_h, float Resolution = Screen_w * Screen_h varchar resolutionstring = screen_w + ' x ' + screen_h Now I want to get the maximum/minimum resolution each user had: Select User_UID, max(resolution) from T_Visits GROUP BY User_UID How can I get the corresponding resolution string ? I mean I can get the max(screen_w) and max(screen_h), but there's no guarantee that the corresponding resolutionstring would be max(screen_w) +' x '+ max(screen_h)

    - by findmeahamper
    I just built a site that relies on certain Unicode characters like &#9398;, but have just realized that IE doesn't show these characters? Is there some meta tag to get the browser to show it or how do you update IE to handle these Unicode characters?

  • How to create programming flowchart/documentation from VB.NET source code?

    - by Greg
    Hi, what tools do you use to create programming flowchart/documentation from VB.NET source code? There are absolutely no comments/documentation at present. I am a beginner, i.e. I tried Sandcastle but it is way over my head and could not get it going, not even with GUI. Fatesoft's CodeVisual To Flowchart is OK but it is almost the same as the code and I still don't understand the code.

  • What kind of cost does Symbian require?

    - by httpinterpret
    Quoted from this answer: Cost of tools: JavaME would be cheapest, followed by Symbian, Android then iPhone. I want to get started with mobile phone programing,but I don't see where Symbian does cost, as its SDK is available for free. Anyone knows? BTW,many people say Symbian only supports Symbian C++, but after reading its document, it seems it also support Java, is this feature newly added?

  • Why is this <p> expanding the whole page?

    - by George Edison
    If you visit this page and shrink your browser window, you will see my problem. [If you want to open the page in a new window, just hold down shift when you click the link.] The answers to the question extend beyond the page margin instead of wrapping. I have spent the last half hour working with Chrome's Inspector and Firefox's DOM inspector - all to no avail. I just cannot figure out why it's doing this.

  • Which JavaScript graphics library has the best performance?

    - by DNS
    I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?

  • What are the most relevant OSS projects for .NET?

    - by Scott Hanselman
    Not a popularity contest, but if you were to elect some in some categories, what would be the names? Here are a few suggested categories. The only criteria I’d insist on would be: needs to be fully OSS, not a one-man show, have some people involved, have source available and with a well-know open source license (hopefully with no distinction between commercial and other uses) Blog engines Wikis Web frameworks WPF frameworks Silverlight frameworks Unit test frameworks (including spec?) ASP.Net tools more specialized frameworks Scott Hanselman and Hamilton Verissimo de Oliveira
