  • Markdown to text/plain and text/html for multipart email

    - by fphilipe
    I’m looking for a solution to send DRY multipart emails in Rails. With DRY I mean that the content for the mail is only defined once. I’ve thought about some possible solutions but haven’t found any existing implementations. The solutions I’ve thought about are: load the text from I18n and apply Markdown for the html mail and apply Markdown with a special output type for the text mail where links are put in parenthesis after the link text bold, italic and other formatting that doesn't make sense are removed ordered and unordered lists are maintained generate only the html mail and convert that to text according to the above conditions Is there any available solution out there? Which one is probably the better way to do it?

  • Is it possible to generate plain-old XML using Haml?

    - by lsdr
    I've been working on a piece of software where I need to generate a custom XML file to send back to a client application. The current solutions on Ruby/Rails world for generating XML files are slow, at best. Using builder or event Nokogiri, while have a nice syntax and are maintainable solutions, they consume too much time and processing. I definetly could go to ERB, which provides a good speed at the expense of building the whole XML by hand. HAML is a great tool, have a nice and straight-forward syntax and is fairly fast. But I'm struggling to build pure XML files using it. Which makes me wonder, is it possible at all? Does any one have some pointers to some code or docs showing how to do this, build a full, valid XML from HAML?

  • How can I progrommatically change the target framework from 4.0 to 3.5 of a project/solution?

    - by scott
    Edit 3: After more googling it looks like you can't have the TargetFrameworkMoniker property in a .NET 3.5 application. So I guess I should be asking a different question. How do I change the Target framework from 4.0 to 3.5? Unfortunately, I can only find stuff on how to go the other way. or better yet how do i progrommatically set the target framework version of a project to something other than 4.0? Original question: I just switched to vs2010. I have an application that uses .net 3.5. It loads plugins which are generated by a different app. The plugins are using .net 4 and there for cannot be loaded. I'm using EnvDTE.Project to create a project and set the settings. I can't find what setting needs to be set for this. Edit 1: I'm generating code for about 50 solutions. When I made the switch from vs2005 to vs2010 the projects in those solutions are defaulting to .NET Framework 4.0. So I need to set the .NET Framework to 3.5 when I am generating the code for these solutions. Edit 2: After a lot of googling I found this. so then I tried this: loProp = vsGetProperty("TargetFrameworkMoniker"); vsSetValue(loProp, ".NETFramework,Version=v3.5"); the definitions for those two methods are below. as far as I can tell they do the same this as project.Properties.Item("TargetFrameworkMoniker").Value = ".NETFramework,Version=v4.0,Profile=Client"; I start getting an Property Unavailable Exception later in the code. When I remove the new lines everything works except the projects target framework is still 4.0. The code generators target framework is 3.5 so I can't use the FrameworkName class like shown in the second example in that link. here is vsGetProperty protected Property vsGetProperty(string aProperty) { bool lbDone = false; int liCount = 0; Property loProp; while (!lbDone && liCount < pMaxRetries) { try { loProp = pProject.Properties.Item(aProperty); lbDone = true; return loProp; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } return null; } and vsSetValue protected void vsSetValue(Property aProperty, string aValue) { bool lbDone = false; int liCount = 0; while (!lbDone && liCount < pMaxRetries) { try { aProperty.Value = aValue; lbDone = true; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } }

  • best content on how to deploy and share a VSTO solution

    - by ooo
    with the push to leverage visual studio and dotnet with office based solutions, especially excel, where is the best article or information on how having office sheet with additional binaries and assemblies is sharable. Do this external code get packaged with the spreadsheet what if people start emailing the spreadsheet around. Is there any overhead of this additional assemblies. Is there risk of the binaries getting detached from the spreadsheet It seems like microsoft has been pushing VSTO for over 5 years now but you read lots of mixed reviews and issues. Are we at the point where companies that do large VBA excel solutions can fully migrate over to dotnet without any real worries?

  • Cant get Tomcat6.0 to work with Windows 7 Environment

    - by CitadelCSCadet
    Prior to upgrading to windows 7, I was able to use Tomcat 6.0, but when I upgraded to the new Windows, and downloaded Eclipse EE, and downloaded the apache content, I am unable to get Apache to run. When I attempt to start my apacher server through either system tray, or even windows services, it gives the followign error screen. "Windows could not start the Apache Tomcat 6 on local computer. For more information review the system event log. Refer to server specific error code 0." I have been able to locate some forums about error code 0, and some other documentation on this problem, but none of the solutions seems to work. One of the solutions I came across said to take the msvcr71.dll (mscvrt.dll on new platforms) and put it into the bin folder of apache. This also did not work. Does anybody know a fix for this problem, or a way to get around it so I can get my server up and running thanks.

  • MongoDB or CouchDB - fit for production?

    - by Alan
    I was wondering if anyone can tell me if MongoDB or CouchDB are ready for a production environment. I'm now looking at these storage solutions (I'm favouring MongoDB at the moment), however these projects are quite young and so I foresee that I'm going to have to work quite hard to convince my manager that we should adopt this new technology. What I'd like to know is: 1) Who is using MongoDB or CouchDB today in a production environment? 2) How are you using MongoDB/CouchDB? 3) What problems (if any) did you come across when you adopted this new storage mechanism (and how did you overcome them)? 4) How did you deal with any migration issues that you had to deal with? 5) Do you have any good/bad experiences with either of these solutions that you'd like to share? Thanks.

  • Connect two daemons in python

    - by Simon
    What is the best way to connect two daemons in Python? I have daemon A and B. I'd like to receive data generated by B in A's module (maybe bidirectional). Both daemons support plugins, so I'd like to shut communication in plugins. What's the best and cross-platform way to do that? I know few mechanisms from low-level solutions - shared memory (C/C++), linux pipe, sockets (TCP/UDP), etc. and few high-level - queue (JMS, Rabbit), RPC. Both daemons should run on the same host, but obviously better approach is to abstract from connection type. What are typical solutions/libraries in python? I'm looking for an elegant and lightweight solution. I don't need external server, just two processes talking with each other. What should I use in python to do that?

  • Update JSON file C# W8 development

    - by AndrewB
    At the moment, I've got a JSON file with content looking like this: { "username": "test", "someNumber":100 } I'm using JSON.Net to fetch the .JSON file from a webserver - C#: var http = new HttpClient(); http.MaxResponseContentBufferSize = Int32.MaxValue; var response = await http.GetStringAsync(URI); var result = JsonConvert.DeserializeObject<DatClass.Result>(response); This works great together with the class getting/setting the properties. However, what I would like to know is whether there's a good way for a user to update the .JSON file through a textbox UI? As in: [textbox - update username] [update button] - username sent to server - .JSON file updated - [textblock - showing updated username in UI]. I'm not looking for exact code solutions, I'm rather looking for good solutions on this, and/or if this is a terrible idea of an easy database(?).

  • Conditional themes in Visual Studio 2008

    - by Bala R
    Can I have different visual studio themes associated to different solutions? Here's my problem. I have two files with sames names that have almost identical contents from two different solutions, open simultaneously. Of course, I have the first solution open and the file from the second solution is opened from explorer and has no connection to the first solution what so ever. Is there any way I can distinguish the the file that belongs to the solution from the other file, just by a different tab color or something like that and without hovering over the tab to look up the path. Thanks

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

    - by user353305
    Hello All, First of all I am very thankful to the owner of this website. I have learned and implement various technologies with the help of solutions provided by the readers. I know the question I asked is posted many time in this forum. And I have tired all of the solutions available, but no luck I may case I am trying to read a dat file which is basically a msg/feed file having more than 22000 Characters. Every line may or may not be of same length. My requirement is to convert the file to fixed line length character file. I have a logic that work well using vb script, however its pretty slow. I have checked with For f/ but no luck. The only delimiter I have is EOT, which i can see in Textpad but not in notepad. I have tried with \n, token=. Please help me in resolving the issue. Regards, Rajiv [email protected]

  • NoSQL for concurrent reads/writes

    - by Mickael Marrache
    After getting some performance issues for an application using a MySQL database, I'm thinking of using NoSQL solutions. My architecture is as follows: One application receives messages from the network at a high throughput (i.e. 50000 messages/sec). Each message is stored in the DB, so it's important for the write rate to be as fast as the arrival rate. Then, I also have some PHP pages that accesses the DB to get the data stored by the other application. It's important for me that the retrieved data is as relevant as possible (i.e. not old data, let's say not more than 5 seconds old). Also, the data is not critical, so I don't need any security mechanism to avoid losing the data. I see there are a lot of NoSQL solutions, but I don't know if they are all relevant. Could you please provide me some directions. Thanks

  • Dynamic Programming resources in C?

    - by EsotericMe
    Hi everyone, I'll be writing the online Google test tomorrow as a fresher. Apparently, they definitely ask one problem on Dynamic Programming? Does anyone know of a good resource for collection of DP problems in C along with solutions? I know what DP is & have used it on an occasion or twice. However I feel to crack a DP problem in test, prior practice of typical problems will make it easier to approach. Any good resources or problem sets with solutions in C will be highly appreciated. Thanks.

  • Solving the problem of finding parts which work well with each other

    - by dotnetdev
    Hi, I have a database of items. They are for cars and similar parts (eg cam/pistons) work better than others in different combinations (eg one product will work well with another, while another combination of 2 parts may not). There are so many possible permutations, what solutions apply to this problem? So far, I feel that these are possible approaches (Where I have question marks, something tells me these are solutions but I am not 100% confident they are). Neural networks (?) Collection-based approach (selection of parts in a collection for cam, and likewise for pistons in another collection, all work well with each other) Business rules engine (?) What are good ways to tackle this sort of problem? Thanks

  • Visual Studio 2005 - strange characters rendered for ANSI text

    - by Apogee
    Hi all, Has anyone seen this odd text rendering issue in VS2005 before? The first line of using statements actually says "using System;". If I copy the line as it is displayed and paste into notepad, the text appears correctly, so clearly the character codes are correct. In addition, the solution compiles and runs correctly. I was thinking it might be due to ClearCase using a different character encoding as all the solutions we're using were freshly checked-out yesterday on to a new build machine, but this is only happening in 2 of our ~30 solutions. Incidentally the same .cs files when opened in VS2008 render correctly on this machine, could this be a corruption in VS2005?

  • How do I get developers to look at our bug tracking page regularly?

    - by abeger
    We've recently started using Trac and are still trying to figure out the best way to use it in our environment. It's great, but it will only be effective if developers look at it once in a while and I'm trying to figure out how to instill that habit in them. I've contemplated several solutions, such as: forcing them to use Trac as their homepage (too draconian) handing out bookmarks to the RSS feeds (same problem--no one will look at them) automatic email notifications (won't drive them to the site and might just annoy them more than anything else) What are some other solutions? What have you tried that worked?

  • Experience with protecting PHP code

    - by Alec Smart
    Hello, I am aware of that there are a number of code obfuscators/licensing programs for PHP. I wanted to know if anyone has actually used these and what their experience has been. Please note I do not want to know the solutions available. I want to know your experience using one of these solutions. Is it worth investing say 200$ purchasing a code obfuscator etc? I honestly would prefer something that does not have a loader etc. I know that it increases the chances of cracking, but I only want it to be a detrimental factor for them. Thank you for your time.

  • How to implement a book preview (2 page spread) without using Flash?

    - by littlejim84
    I'm looking into a solution for work, where you have a two page spread of the book to preview. Either side of this, you can hover in the corner to create a pseudo-flip and then click the mouse button to actually turn the page. I know there is many Flash solutions out there, but in this case we cannot use it... So we are looking for a possible solution that can work across all major browsers (yes, including IE6)... I looked a few canvas solutions, but with Google's canvas extension for IE, these will terribly slow. So was thinking about an SVG/VML solution, like Raphael Javascript library. This could be good, but then trying to look into how to code this, without examples, could be a challenge with the time constraint. Is there a solution out there that fits (or almost fits) this problem?

  • Is there a way to have one project build another in Visual Studio?

    - by Martin Neal
    We are finally getting a source control system in place at work and I've been in charge of setting it up. I've read that it's usually good practice to not include binaries in source control so I haven't. However, we have two all-purpose utility projects (each in their own solution) that generate utility .dll's which are included in almost all of our other projects (all each in their own separate solutions). We add references to the utility dll from our projects. I would like to have our solutions set up in such a way that if the reference dll isn't built, the solution will build the dll for itself, much in the same way a make file checks for its dependencies and builds them when they're out of date or missing. I'm new to build processes with VS so try to keep the answers simple. Any links to general build process overview tutorials would be great too. Googleing for VS references returns a bunch of how-to add references links which is not exactly what I want.

  • 3 DIV's - Center Middle and Others taking up rest of room

    - by Adam
    I need to have 3 DIV's - you can see 3 colors in the above image. The middle DIV needs always be 960px and alls needs to be centered (you can see the 2 grey lines above). The other 2 DIV's need to take up all the other available space. If I zoom in and out of the page the red and yellow DIV's need to expand with the page while the middle green one remains centered. I've tried DIV solutions and Table solutions and I can't get it to fit. HTML <div id="div1" style="background-color:red"></div> <div id="div2" style="background-color:red"></div> <div id="div3" style="background-color:red"></div> any advice would be appreciated. thx ** Update: http://jsfiddle.net/scxAq/ working on this... with limited success...

  • VIM: Columnvise Increment inside and outside?

    - by hhh
    By outside, I want solutions that does not use Vim's scripting hacks but try to reuse certain basic *ix tools. Inside Vim stuff asks for solutions to get the column-increment with inside stuff such as scripting. 1 1 1 2 1 3 1 ---> 4 1 5 1 6 . . . . Vim has a script that does column-vise icrementing here. It has gathered about 50/50 ups and down, perhaps tasting a bit reinventing-the-wheel. How do you column-increment stuff in Vim without using such script? Then the other question is, how do you column-increment stuff without/outside Vim? Most elegant, reusable and preferrably-small wins the race!

  • Using "Go To Controller" and "Go To View" in Visual Studio 2008 when controllers are in different as

    - by ElvisLives
    The title is basically the question. We decided to move our controller classes to a separate library and reference it in our asp.net mvc 2 application. It works just fine when running the application, meaning the controllers are being referenced while the application is running. But when doing development (in Visual Studio 2008) and I am in a View and try to use the context menu "Go To Controller" it can't find our controllers in the new assembly. Same with when I am inside a controller, I don't have the Context menu to "Add View" or "Go To View" anymore. Does anyone one know how to remedy this? I searched like crazy but haven't found any solutions or even half solutions. Thanks!

  • How to organize Windows Phone code base to target both 7.x and 8 platforms

    - by ljubomir
    I took over a Windows Phone project which was previously targeting WP 7.1 platform, and with the recent announcement of the new platform it should target WP 8 as well. My VS 2010 solution consists on several projects (Data access, Model, Tests and WP7 client app) and i am wandering on how to include support for WP8. I have to note that the code-base is not compatible with WP8, due to usage of Toolkit controls and other 3rd party libraries targeted for WP7.1 specifically. Also there is another problem with the Visual Studio versions - WP7.1 can work with VS 2010, but WP8 requires VS 2012. Should i move the whole code-base to VS 2012? Any good advice on how to organize code-base in a most meaningful way in order to avoid duplication and possible painful maintenance? I am thinking between one solution - multiple projects vs. multiple solutions - reusable projects approach. Code duplication (like two separate folders/solutions) should be the least possible approach (fallback).
