• What C#/SQL Server feature did someone show you that made you say Wow!

  - by Randy Minder

  It's late Friday afternoon, and my mind is checking out for the week. So I thought I'd ask a light-hearted, interesting, question. Yesterday a co-worker showed me how he managed to save quite a bit of code and improve code reuse through the use of an anonymous delegate and the use of the Action function. My first thought was, "Wow, I had no idea you could do that!". I'm curious what sort of things someone showed you, either in c# or SQL Server, that made you stop and think, "Wow!". Randy

• Using boost::asio::async_read with stdin?

  - by yeus

  hi poeple.. short question: I have a realtime-simulation which is running as a backround process and is connected with pipes to the calling pogramm. I want to send commands to that process using stdin to get certain information from it via stdout. Now because it is a real-time process, it has to be a non blocking input. Is boost::asio::async_read in conjunction with iostream::cin a good idea for this task? how would I use that function if it is feasible? Any more suggestions?

• Is there way to find when self signed certificate will expire for Adobe Air application?

  - by tyler

  Hi, I have to release my Adobe Air application but the build process was "setup" by a different developer. (He made a self signed cert and wrote a batch file to call adt for packaging the application). Adobe mentions that such self signed certificates are valid for 5 years. Now I have no idea when that certificate will expire as I don't know when it was created. Also will my installed application stop working on expiry or only new installations will fail ? Thanks.

  - by Stephan

  Hi , I have the following XML code : <root> <a><l_desc/></a> <b><l_desc>foo</l_desc></b> <c><l_desc>bar</l_desc></c> </root> I want to match the l_desc nodes with a or b nodes as parent.

Do you have any idea for reducing the first expression ? Stéphan

• Subversion Repository Layout

  - by Tim Long

  Most subversion tools create a default repository layout with /trunk, /branches and /tags. The documentation also recommends not using separate repositories for each project, so that code can be more easily shared. Following that advice has led to me having a repository with the following layout: /trunk /Project1 /Project2 /branches /Project1 /Project2 /tags /Project1 /Project2 and so on, you get the idea. Over time, I've found this structure a bit clumsy and it occurred to me that there's an alternative interpretation of the recommendations, such as: /Project1 /trunk /branches /tags /Project2 /trunk /branches /tags So, which layout do people use, and why? Or - is there another way to do things that I've completely missed?

• Google chrome extension: local storage

  - by Rohan

  Hi there I'm developing an extension for Google Chrome, and have run into some trouble.I created an options.html page and added it to the manifest.json file.The page shows properly. I saved the options, and then went back to the page on which the extension is supposed to run. Unfortunately, the Local storage for the options was returning a 'null' instead of the option. If I set the local storage option directly from the extension's JS script, it works fine but not if it was set from the options page. Any idea how i can access the options.html local storage values from my Javascript file in the extension? thanks!

• Are database triggers evil?

  - by WW

  Are database triggers a bad idea? In my experience they are evil, because they can result in surprising side effects, and are difficult to debug (especially when one trigger fires another). Often developers do not even think of looking if there is a trigger. On the other hand, it seems like if you have logic that must occur evertime a new FOO is created in the database then the most foolproof place to put it is an insert trigger on the FOO table. The only time we're using triggers is for really simple things like setting the ModifiedDate.

• jQuery,Input buttons work in markup, but not when prepended?

  - by thatryan

  I have to buttons, image input that work fine when in the markup like this, <input type="image" class="play" src="images/play.png" /> <input type="image" class="pause" src="images/pause.png" /> But as soon as I try to prepend() it to a generated they still appear, but the click function does not work anymore. $('.gallery-nav').prepend('<input type="image" class="play" src="images/play.png" /><input type="image" class="pause" src="images/pause.png" />'); Any idea why? Thank you.

• What is Boost missing?

  - by Robert Gould

  After spending most of my waking time on Stack Overflow, for better or for worse, I've come to notice how 99% of the C++ questions are answered with "use boost::wealreadysolvedyourproblem", but there must definitely be a few areas Boost doesn't cover, but would be better if it did. So what features is Boost missing? I'll start by saying: boost::sql (although SOCI should try to become a legal part of boost) boost::json (although TinyJSON should try to become a legal part of boost) boost::audio (no idea about a good boost-like C++ library) PS: The purpose is to compile a reasonable list, and hopefully Boost-like solutions out there that aren't yet a part of Boost, so no silly stuff like boost::turkey please.

• Mapping class properties to generic columns in table .NET

  - by Tony_Henrich

  I have have a SQL Server table which has generic names like Text1, Text2.. etc. The table was designed like this because the same structure is used for different projects. I have a class in .NET which has properties. Say a Customer class has a property called FirstName. How can I do the mapping from FirstName to Text1 just once (central place) in the application so that I don't have to remember and hard code the mappings all over the app when I create the different DAL methods? For example, I want the app to know when I want to update, insert a FirstName, the DAL automatically uses Text1. Basically I don't have to remember which property goes to which column. The idea is so the developers do not map the properlies/columns in a wrong way. It's always consistent. Note: Database inserts, updates and deletes are allowed through stored procedures only.

• Choice of primary index for mysql innoDB

  - by Saif Bechan

  I have an auction website where users can place a bid on a product. Now i have a primary index on the bid table for easy access of the last places bid on the product. This index is just a unique auto incrementing value. During the week this number becomes huge!! I was wondering if this is a good setup for the primary key in an innoDB table. The bids table exist of the following important fields: table: bids fields: user_id,product_id,bid So what i want to do is make the primary of these 3 fields combined. Is this a good idea or is this just too much for innoDB keys.

• LINQ: Dot Notation vs Query Expression

  - by Martín Marconcini

  I am beginning to use LINQ in general (so far toXML and toSQL). I've seen that sometimes there are two or more ways to achieve the same results. Take this simple example, as far as I understand both return exactly the same thing: SomeDataContext dc = new SomeDataContext(); var queue = from q in dc.SomeTable where q.SomeDate <= DateTime.Now && q.Locked != true orderby (q.Priority, q.TimeCreated) select q; var queue2 = dc.SomeTable .Where( q => q.SomeDate <= DateTime.Now && q.Locked != true ) .OrderBy(q => q.Priority) .ThenBy(q => q.TimeCreated); Besides any mistake I may have made in the syntax or a missing parameter or difference, the idea is that there are two ways to express the same thing; I understand that the first method has some limitations and that the "dot notation" is more complete, but besides that, are there any other advantages?

• Creating a QLineEdit search field for items displayed in a QListView

  - by krunk

  I want to create a search field that filters the items shown in a QListView. Basically the user could type in "foo" and only items with "foo" in the DisplayRole are shown. I already have a few ideas on how to do this, but thought I'd ask those more experienced than I. My idea would be to use some signals and slots to set a filter in the QAbstractItem model and trigger an update() in the QListView. Are there any helper methods in QListView for filtering I may have missed? Is there a canonical way of handling this I haven't run across?

• Can I monitor traffic on my Incoming Dialup connection using Wireshark?

  - by BeeBand

  Hi, I am trying to create a RAS server in XP Pro. The idea is to log in to this server via a dialup connection. I have set up a new network connection via the New Connect Wizard in XP - according to this tutorial on techrepublic. I am sure that the modem and the connection is working, I have tested it. However, I want to monitor incoming network traffic on this connection. So I thought I would use Wireshark. The problem is that Wireshark does not list this incoming connection on the front page. It lists all my other network connections, ( e.g. my ethernet connection ) but not this one. Whats the best way to monitor traffic on this connection?

• Dynamic openrowset in T-Sql Function or viable alternative?

  - by IronicMuffin

  I'm not quite sure how to phrase this. Here is the problem: I have 1-n items that I need to join to a different system (AS400) to get some data. The openrowset takes forever if I specify the where criteria outside of the openrowset, e.g.: select * from openrowset('my connection string', 'select code, myfield from myTable') where code = @code My idea was to create a function that takes in the item number and uses dynamic sql to inject it into the openrowset string, a la: declare @cmd varchar(1000) set @cmd = 'select * from openrowset('my connection string', ''select code, myfield from myTable where code = ' + @code + ''')' Apparently I can't use the insert.. exec.. strategy inside of a function. Is there any better way to achieve this? I was going to use this in joins where I needed the external data using cross apply. I'm not married to tvf and cross apply, but I do need a method of getting this data quickly. Thanks for any help.

• basic boost date_time input format question

  - by Chris H

  I've got a pointer to a string, (char *) as input. The date/time looks like this: Sat, 10 Apr 2010 19:30:00 I'm only interested in the date, not the time. I created an "input_facet" with the format I want: boost::date_time::date_input_facet inFmt("%a %d %b %Y"); but I'm not sure what to do with it. Ultimately I'd like to create a date object from the string. I'm pretty sure I'm on the right track with that input facet and format, but I have no idea how to use it. Thanks.
