  • problem with mingw32-make

    - by stupid_idiot
    hi, I'm quite new with makefile but I don't think the problem I got is caused by my noobness. Somehow if I try to execute mingw32-make from Users/(user)/Documents/myProject the output is "mingw32-make: *** No targets specified and no makefile found. Stop." if I just drag the folder with it to my Desktop and execute make, it works. Any ideas why does it behave like this or perhaps how to make it work from Documents directory too?

  • Remember (persist) the filter, sort order and current page of jqGrid

    - by Jimbo
    My application users asked if it were possible for pages that contain a jqGrid to remember the filter, sort order and current page of the grid (because when they click a grid item to carry out a task and then go back to it they'd like it to be "as they left it") Cookies seem to be the way forward, but how to get the page to load these and set them in the grid before it makes its first data request is a little beyond me at this stage. Does anyone have any experience with this kind of thing with jqGrid? Thanks!

  • How to ignore noiseXXX.txt files for a specific column in SQL Server 2005?

    - by John MacIntyre
    I have a product table where the description column is fulltext indexed. The problem is, users frequently search a single word, which happens to be in the noiseXXX.txt files. We'd like to keep the noise word functionality enabled, but is there anyway to turn it off just for this one column? I think you can do this in 2008 with the SET STOPLIST=OFF, but I can't seem to find similar functionality in SQL Server 2005.

User (Session) ID (Session) Status Client Name Session (Name) Programmatic in C# would be best but I could also wrap a cmd line tool.

  • Is ajax + comet + asp.net scalable ?

    - by pixel3cs
    Thinks at a backgammon online multiplayer game with over 100, or even 1000 online users. The game communication is done using Ajax + 3 seconds Comet connection interval + ASP.NET technology. Is this a real scenario ? Didn't so many Comet open connections block the server resulting in big latency ?

  • Are people really using Google App Engine, or they are just playing with it because "the cloud is co

    - by Bozho
    Since there are 1500+ questions for google-app-engine, I was wondering: what are people actually using it for? are they doing something for their companies or startups? are they just playing around with it because "the cloud is cool"? are they using it because it's the "java free hosting"? (answers from actual GAE users are preferable, but logical assumptions from others are welcome) Update: I was asking (as tagged) about the Java aspect of GAE.

    Hi, I have a file which I want users to download only once. After it's done downloading, the file is no longer available. Outside of setting up a streaming system, is there any way I can set some sort of callback up to say the file is done downloading on the client's computer? Thanks

  • How can I improve my select query for storing large versioned data sets?

    - by Jason Francis
    At work, we build large multi-page web applications, consisting mostly of radio and check boxes. The primary purpose of each application is to gather data, but as users return to a page they have previously visited, we report back to them their previous responses. Worst-case scenario, we might have up to 900 distinct variables and around 1.5 million users. For several reasons, it makes sense to use an insert-only approach to storing the data (as opposed to update-in-place) so that we can capture historical data about repeated interactions with variables. The net result is that we might have several responses per user per variable. Our table to collect the responses looks something like this: CREATE TABLE [dbo].[results]( [id] [bigint] IDENTITY(1,1) NOT NULL, [userid] [int] NULL, [variable] [varchar](8) NULL, [value] [tinyint] NULL, [submitted] [smalldatetime] NULL) Where id serves as the primary key. Virtually every request results in a series of insert statements (one per variable submitted), and then we run a select to produce previous responses for the next page (something like this): SELECT t.id, t.variable, t.value FROM results t WITH (NOLOCK) WHERE t.userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') AND t.id IN (SELECT MAX(id) AS id FROM results WITH (NOLOCK) WHERE userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') GROUP BY variable) Which, in this case, would return the most recent responses for the variables "internat", "veteran", and "athlete" for user 2111846. We have followed the advice of the database tuning tools in indexing the tables, and against our data, this is the best-performing version of the select query that we have been able to come up with. Even so, there seems to be significant performance degradation as the table approaches 1 million records (and we might have about 150x that). We have a fairly-elegant solution in place for sharding the data across multiple tables which has been working quite well, but I am open for any advice about how I might construct a better version of the select query. We use this structure frequently for storing lots of independent data points, and we like the benefits it provides. So the question is, how can I improve the performance of the select query? I assume the nested select statement is a bad idea, but I have yet to find an alternative that performs as well. Thanks in advance. NB: Since we emphasize creating over reading in this case, and since we never update in place, there doesn't seem to be any penalty (and some advantage) for using the NOLOCK directive in this case.

  • About Backward Compatibility of .NET Framework 4

    - by wuminqi
    We have an WPF Application build on .net framework 3.5. Some testers find if they uninstall .net framework 3.5, but install .net framework 4.0, our APP fails to launch itself. Dose this mean that .net framework 4.0 does not include all 3.5 libs, and users have to install .net 3.5 even though they have 4.0? I see here are some migration issues listed by Microsoft http://msdn.microsoft.com/en-us/library/ee941656.aspx#windows_presentation_foundation_wpf Are they all breaking changes so that the backward compatibility is ruined? Thanks

  • What tools do you use to share knowledge amongst developers in your company?

    - by Chris Ross
    I'm looking for some good tools that help to share tips, best practices, company standards, etc. amongs developers in my company. Two tools I'm currently considering are a wiki (screwturn wiki) or Sharepoint 2010. I'm wondering if there is something better suited to the task, or any input anyone has on this subject. I'd prefer something that's windows based (i.e. runs on IIS, can authenticate users against Active Directory etc) but I am open to anything.
