  • Float as DateTime

    - by lp1
    SQL Server 2008 I almost have, I think, what I'm looking to do. I'm just trying to fine tune the result. I have a table that stores timestamps of all transactions that occur on the system. I'm writing a query to give an average transaction time. This is what I have so far: With TransTime AS ( select endtime-starttime AS Totaltime from transactiontime where starttime > '2010-05-12' and endtime < '2010-05-13') Select CAST(AVG(CAST(TotalTime As Float))As Datetime) from TransTime I'm getting the following result: 1900-01-01 00:00:00.007 I can't figure out how to strip the date off and just display the time, 00:00:00:007. Any help would be appreciated. Thank you.

  • How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

    - by Ben Robbins
    At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).

  • Getting error that the database is locked when refreshing the page

    - by acidzombie24
    The title is a joke. However it is serious as far as my app is concerned. I am running apache with mod mono and my asp.net app is using mono sqlite as its db. When i refresh the page twice i get the DB is locked error. The folder it is in is chmod 777. The webapp is creating sqlite.db and sqlite.db-journal but it doesnt seem to be able to delete the journal. i'm confused. What permissions do i need to set these? i tried precreating the files using 777 and had no luck.

  • GameKit server disconnect makes session invalid

    - by Markus
    Hi everyone, I'm trying to build a 4 player multiplayer game using GameKit. I tried many things and I'm currently using client/server mode, meaning that I have 1 session in GKSessionModeServer and 3 other sessions connecting to this one in GKSessionModeClient. My goal is, that when a user leaves the game or gets disconnected for whatever reason, that the others can continue their game. So far this works if any of the Clients leave the game, but if the Sevrer leaves the game, send and receive calls are not reaching the other peers anymore. I tried the same with 4 peers in GKSessionModePeer with the same result (where the player who accepts connections cannot quit). Does anyone had better success in making this work? Any help is highly appreciated. Thanks!

  • Programmatically inviting contacts to Google Chat

    - by DBa
    Hello folks, I'm writing a sync application for Lotus Notes and Google (I know, there are some of them out there, but they are either not free or sync only calendar (or only contacts) and most of them cannot deal with local mailfiles). This works so far, but I have a problem when syncing contacts: under certain circustances, the contacts have to be deleted and recreated in Google. This causes them to disappear from the chat list in GMail and the people have to be re-invited manually. Is there any way to send these invites through the API? Thanks in advance DBa

  • How to extract a single function from a source file

    - by Adam Matan
    Hi, I'm working on a small academic research about extremely long and complicated functions in the Linux kernel. I'm trying to figure out if there is a good reason to write 600 or 800 lines-long functions. For that purpose, I would like to find a tool that can extract a function from a .c file, so I can run some automated tests on the function. For example, If I have the function cifs_parse_mount_options() within the file connect.c, I'm seeking a solution that would roughly work like: extract /fs/cifs/connect.c cifs_parse_mount_options and return the 523 lines of code(!) of the function, from the opening braces to the closing braces. Of course, any way of manipulating existing software packages like gcc to do that, would be most helpful too. Thanks, Udi EDIT : The answers to Regex to pull out C function prototype declarations? convinced me that matching function declaration by regex is far from trivial.

  • Where to put WPF specific code when using MVVM

    - by Surfbutler
    I'm just getting up to speed on MVVM, but all the examples I've seen so far are binding View controls to simple non-WPF specific data types such as strings and ints. However in our app I want to be able to set a button's border brush based on a number in the Model. At the moment, I translate the number into a brush in the ViewModel to keep the View XAML only, but is that right? I don't like putting WPF specific code in the ViewModel, but equally I don't like the idea of putting code-behind on my View panel. Which is the best way? Thanks

  • What we call this kind of chaining in C#

    - by Thinking
    Can you please tell me what kind of construct in C# is this. Code Golf: Numeric equivalent of an Excel column name C.WriteLine(C.ReadLine() .Reverse() .Select((c, i) => (c - 64) * System.Math.Pow(26, i)) .Sum()); Though I am new to C# (only two months exp so far), but since the time I have joined a C# team, I have never seen this kind of chaining. It really attracted me and I want to learn more about it. Please give some insight about this.

  • Anyone Using the Abyss Web Server

    - by infocyde
    Just curious to see if anyone is using the Abyss Web Server for any projects. http://www.aprelium.com/ I've checked it out a few times, had it running a few ASP.Net demo sites, but haven't gotten to far with it. I like the ease of use, but I'm thinking both IIS and Apache out class Abyss for the most part. Has anyone used it? If so, what is your experience? I ask because I'm tempted to use if for some projects, but if it isn't worth the investment I probably won't. Thanks for your time.

  • MySQL count problem

    - by Skuja
    I have 3 tables users(id,name),groups(id,name) and users_groups(user_id,group_id). users and groups have many to many relationship, so the third one is for storing users and groups relations. I would like to select all the data from groups with user count in each group. So far I came up with this: SELECT groups.*, COUNT(users_groups.user_id) AS user_count FROM groups LEFT JOIN users_groups ON users_groups.group_id = groups.id The problem is that query result is not returning any of groups which has no users (users_groups doesnt have any records with group_id of those groups). How should I create my query to select all the groups and they user count, or user count as 0 if there are no users for that group?

  • How do I prevent an https response from throwing an AuthenticationException with Fiddler running?

    - by Ichabod Clay
    Relative newbie to C# here :) I'm currently creating a web link scraper and having issues with the responses I'm getting when trying to login to the website via my program. I'm trying to use Fiddler to see if my program is sending the proper data, but my program is throwing an AuthenticationException when trying to get a response from the site with Fiddler running. The requests are being sent over HTTPS and Fiddler's certificate is the cause of the excepting being thrown. My question is, what can I implement into my program to have it disregard the certificate authentication? As far as my program goes, the requests and responses are being handled by HttpWebRequest and HttpWebResponse classes.

  • ASP.NET MVC / Linq-to-SQL classes: Can I get it to infer readable display names?

    - by Gary McGill
    If I have a table Orders with fields CustomerID, OrderID and OrderDate, then the "Linq-to-SQL classes" generated class will be called Orders, with members called CustomerID, OrderID and OrderDate. So far so good. However, if I then do Html.LabelFor(m => m.OrderDate) then the generated text will be "OrderDate" instead of "Order Date". I tried using Order_Date as the field name, but that didn't work. Is there any way to get it to infer a better display name? [I know that I can use data annotations to specify the display name explicitly, but I really don't want to do that for all my classes/members - I just want it to work by convention.]

  • A submenu (`ToolStripMenuItem`) does not show automatically.

    - by czuk
    I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

  • How to stream an HttpResponse with Django

    - by muudscope
    I'm trying to get the 'hello world' of streaming responses working for Django (1.2). I figured out how to use a generator and the yield function. But the response still not streaming. I suspect there's a middleware that's mucking with it -- maybe ETAG calculator? But I'm not sure how to disable it. Can somebody please help? Here's the "hello world" of streaming that I have so far: def stream_response(request): resp = HttpResponse( stream_response_generator()) return resp def stream_response_generator(): for x in range(1,11): yield "%s\n" % x # Returns a chunk of the response to the browser time.sleep(1)

  • Writing secure java code with RMI

    - by jtnire
    Hi Everyone, This may seem like a very broad question, but any help is appreciated. I have a client/server solution written in java which uses the Cajo project (which uses RMI). I just want to try and make my solution as secure as possible, given the sensitive data that will be transferred between server and client. So far, my ideas are to make all my classes "final" as well as throw a "non-serializable" exception for all my classes in the server (except for the object bound in the RMI registry, and any objects that actually do need to be transferred of course). Can anyone think of any other ideas? I know that someone could write a malicious client - this isn't hard to do as you can find out the remote object's API using reflection. However is there anything I can do to protect a malicious client access classes/objects within the server that they are not supposed to access? Many Thanks

  • What is the point of heightmaps?

    - by Jake Petroules
    I've been pondering this question awhile now... many 3d engines support advanced terrain rendering using quadtrees, LOD... all the features you expect. But every engine I've seen loads height data from heightmaps... grayscale bitmaps. I just can't understand how this is useful - each point in a heightmap can have one of 256 values. But what if you wanted to model Mt. Everest? with detail of 1 meter, or even greater? That's far outside the range of 256. Of course I understand that you can implement your own terrain format to achieve this, but I just can't see why heightmaps are so widely used despite their great limitations.

  • URL Mapping prefix in Grails

    - by Furuno
    Recently, I'm trying to migrating my application from CakePHP to Grails. So far it's been a smooth sailing, everything I can do with CakePHP, I can do it with much less code in Grails. However, I have one question : In CakePHP, there's an URL Prefix feature that enables you to give prefix to a certain action url, for example, if I have these actions in my controller : PostController admin_add admin_edit admin_delete I can simply access it from the URL : mysite/admin/post/add mysite/admin/post/edit/1 mysite/admin/post/delete/2 instead of: mysite/post/admin_add mysite/post/admin_edit/1 mysite/post/admin_delete/2 Is there anyway to do this in Grails, or at least alternative of doing this?

  • As a team should we develop locally and merge into the dev server, or develop on the dev server?

    - by CogitoErgoSum
    Hey, Recently I was tasked with writing up formal procedures for a team based development enviroment. We have several projects with multiple modules each. Right now there are only two programmers, however there are plans to expand to 4-6 programmers. Each programmer will be working on the same project and possibly pages which may cause over writing or error issues. So far the ideal solution I have thought up is: Local development (WAMP/VM or some virtual server instance on their own machine). Once a developer has finished their developments, they check it into the CVS Repository and merge it wih other fixes etc. The CVS version is then deployed to the primary dev server for testing by the devs. The MySQL DAtabases are kept on the primary dev server and users may remotely connect to it. Any Schema / Data alterations are run through a DB Admin who will notify all devs of any DB Changes (Which should be rare). Does anyone see an issue with this or have a better solution?

  • linq to xml and namespaces

    - by scott
    I'm always so excited to get a chance to use linq to xml and then I run into the same PITA issue with namespaces. Not sure what is wrong with me but I can never quite grok what is going on. Basically I just need to get the value of the responseCode element and so far I have had no luck :( <?xml version="1.0" encoding="IBM437"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Body> <ns1:ActionResponse xmlns:ns1="http://cbsv.ssa.gov/ws/datatype"> <ns1:responseCode>0000</ns1:responseCode> <ns1:responseDescription>Successful</ns1:responseDescription> </ns1:ActionResponse> </soapenv:Body> </soapenv:Envelope>

  • Shared WCF client code between .NET and Silverlight apps?

    - by Eduardo Scoz
    I'm developing a .NET application that will have both a WinForms and a Silverlight client. Although the majority of code will be in the server, I'll need to have quite a bit of logic in the clients as well, and I would like to keep the client library code the same. From what I could figure out so far, I need to have two different project types, a class library and a Silverlight class library, and link the files from one project to the other. This seems kind of lame, but it works for simple code. My problem, though, is that the code generated by the SVCUtil.exe to access WCF services is different from the code generated by the slsvcutil.exe, and the silverlight code is actually incompatible with the .NET one: I get a bunch of problems with the System.ServiceModel.Channel classes when I try to import the class into .NET. Has anybody done anything similar to this before? What am I doing wrong?

  • How do I stop the scriptaculous blind-down effect from flickering when element has padding?

    - by ro
    Hi all, it seems that when the blind down effect is used on an element with padding it looks a bit awkward. It seems to blind down too far and then jumps back. It's a very subtle thing but is really annoying. I don't have an online example but if you go to the demo on github and give the element a padding-top or bottom with firebug or something you'll see what I mean. http://wiki.github.com/madrobby/scriptaculous/effect-blinddown Anybody found a way to stop it?

  • How can I determine img width/height of dynamically loaded images in IE?

    - by Jens
    My markup is a simple div element with id 'load'. Using jQuery I then load a list of image elements into this div: $('#load').load('images.html', { }, function() { $(this).onImagesLoad({ selectorCallback: function() { ....do something.... } }); }); where images.html is a list like this: <img src='1.jpg' caption='img 1'> <img src='2.jpg' caption='img 2'> ... To ensure that all images are loaded completely, I use the onImagesLoad plugin. This, so far, works just fine on all browsers. However, on IE8 (and I assume other versions of IE also) when I then iterate over the img elements, I am unable to determine the width/height of the images loaded. The image.context.naturalWidth and naturalHeight attributes don't seem to work. How do I get a hold of the images' dimension? Thanks heaps :)
