• Porting existing code from C# 2.0 to C#3.0 and .Net 3.5 (possibly .net 4.0)

  - by kanad

  Our one and only enterprise application suite has been developed over last 3 years using C# 2.0 on .Net 3.0. We use winforms and WCF heavily. The development tools is VS 2005 Pro / TFS 2005 / Resharper 3.1 As technical lead I obviously understand the benefits in a move to C#3.0 and .Net 3.5. But I want to convince management for a move to C#3.0, .Net 3.5, VS 2008 and TFS 2008. They will obviously be interested in things like productivity, cost, quality etc. Please suggest me some ideas on how best to make my case. Given that this may not happen till mid next year am I better off to hold till VS 2010 and .Net 4.0 is out.

• ModX navigation menu with "wayfinder" snippet

  - by user1219432

  I have a main navigation at the top of the site. And a subnavigation at left of my site. For example: At the top there are these topics: Cars | Trees | Jobs | ... So when you click on "Jobs" there should be the subnavigation of "Jobs" at left, like... Construction Jobs Engineering Jobs Retail Jobs ... The first (top) navigation is easy to achieve: [[!Wayfinder? &startId=0 &level=1 ]] How can I realize the second navigation, so that only the documents are listed that are under the parent document?

• I need a very simple PHP database front-end admin panel; a simple records editor for a specified tab

  - by Lansen Q

  Hi there, I am looking to add some dynamics to our corporate website. This is a secondary role so I'd rather not be spending a ton of time on it. At this point, all I need is a simple PHP script where a non-technical user can pull up and manage the records in a MySQL table. There's only one table of data to be managed; it's just that it will be accessed and updated quite frequently. I recall that Grails' default scaffolding feature has precisely this: list of entries with the ability to add, edit and delete, with no nonsense. What would be the best tool to use for this? I would rather not be writing it from scratch, as this will take me quite some time. It seems like the kind of thing that ought to exist somewhere. Thanks!

• What format is your documentation in?

  - by Ek0nomik

  I am going to be writing documentation for two web services that I developed, and I started wondering what people on here do for documentation. Do you create it in an HTML file so it can be viewed in the browser? Word document? Wiki? What do you guys/gals use? I was originally leaning towards creating an HTML page since it seems a little more open and friendly than a word document. Plus I can use the prettify javascript to make code samples look nice. Our company has a Sharepoint though, so an HTML file may not be the best choice given that most documentation is put up in spreadsheets and word documents.

• What are the differences between struct and class in C++

  - by palm3D

  This question was already asked in the context of C#/.Net. Now I'd like to learn the differences between a struct and a class in (unmanaged) C++. Please discuss the technical differences as well as reasons for choosing one or the other in OO design. I'll start with an obvious difference: If you don't specify public: or private:, members of a struct are public by default; members of a class are private by default. I'm sure there are other differences to be found in the obscure corners of the C++ specification.

• Communication between .net winform and webform

  - by Pablo

  Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

• Bringing Scala into my company

  - by raichoo

  Hi, Now i know that this one is actually not a very technical question but one that has been bothering me for some time. Actually we are using a lot of C++ and PHP at our company and some of our developers are really hoping for a new and modern language to come by to help us getting more productive. I have been talking about what scala can do and the other coders seem to gain some interest in the language. The tough job is, how do you convince your boss to consider scala as a language for the company. I saw the presentation "Sneaking Scala into your company", but it deals with the situation that you are using Java at your company which we don't. How do you fight of the usual "that is just esoteric stuff" and "we can already do that in $LANGUAGE" arguments. I was planing to give a talk about Scala, and since I don't have much time I need Killer Arguments. How did you guys do it? Regards, raichoo

• How can you prevent a window being captured by Print-Screen?

  - by John

  I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

• Upload file from client machine to server - prepopulate file picker path?

  - by user246114

  Hi, I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like: <input type="file" name="datafile" size="40"> This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example. I don't see how this is possible, just wondering if something like that exists, Thank you

• Regex: How to leave out webding font characters?

  - by DS

  Hi, I've a free text field on my form where the users can type in anything. Some users are pasting text into this field from Word documents with some weird characters that I don't want to go in my DB. (e.g. webding font characters) I'm trying to get a regular expression that would give me only the alphanum and the punctuation characters. But when I try the following, the output is still all the characters. How can I leave them out? <html><body><script type="text/javascript">var str="???????";document.write(str.replace(/[^a-zA-Z 0-9 [:punct]]+/g, " "));</script></body></html>

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

• Possible to use Javascript to access the client side's network(knowingly)

  - by Earlz

  I recently found an exploit in my router to basically give me root access. The catch? There is a nonce hidden form value that is randomly generated and must be sent in for it to work that makes it difficult to do "easily" So basically I'm wanting to do something like this in javascript: get http://192.168.1.254/blah use a regex or similar to extract the nonce value put the nonce value into a hidden field in the current page submit the form by POST to http://192.168.1.254/blah complete with the nonce value and other form values I want to send in. Is this at all possible using only HTML and Javascript? I'm open to things like "must save HTML file locally and then open", which I'm thinking is one way around the cross domain policy. But anyway, is this at all possible? I'm hoping for this to be able to run from at least Firefox and Chrome. The audience for this is those with some technical know how.

• Query Mongo Db and filter by associative array key

  - by Failpunk

  How can I search for results in Mongo DB documents using an associative array key. Something like: SELECT * FROM table WHERE keyword like '%searchterm%'; Here is the basic document structure [id] => 31605 [keywords] => Array ( [keyword1] => Array ( [name] => KeyWord1 ) [keyword2] => Array ( [name] => KeyWord2 ) ... ) I would like to do a search within the keywords array on the associative array key [keyword1, keyword2]. The issue is that the name key holds the case-sensitive version of the keyword and the array key is the lower-case keyword name. I could store the lowercase keyword twice, but that seems silly.

• Reduce text length to fit cell width in a smart manner

  - by Andrei Ciobanu

  Hello, I am in project where we are building a simple web calendar using Java EE technologies. We define a table where every row is an employee, and every column represents an hour interval. The table width and column widths are adjustable. In every cell we have a text retrieved from a database, indicating what the employee is doing / should do in that time interval. The problem is that sometimes the text in cells is getting bigger than the actual cell. My task is to make the text more "readable" by reducing it's length in a "smart way" so that it can fit in the cell more "gracefully". For example if initially in a cell I have: "Writing documents", after the resize I should retrieve: "Wrtng. dcmnts" or "Writ. docum." so that the text can fit well. Is there a smart way to do it ? Or removing vocals / split the string in two is enough ?

• WAMP + Pear installation issue

  - by Industrial

  Hi guys, I am trying to install PEAR in my WAMP-server. The go-pear.bat is running as intended, but when it comes to changing the directories, it all goes wrong.

• Questions to ask a client before beginning a website

  - by Jason

  I am aware of this question which deals with the technical aspects of website construction, but I was unable to find any place with suggestions on knowledge you must obtain from a client before undergoing a project. As someone who freelances on the side, I think this could be incredibly useful. What important questions must one ask the client (and require an answer to) before undergoing a website? or, in other words, What must you know about the project before starting it? This can range from "When do I get paid?" to "How many pages will the site be?". I believe this is relevant to programming because you must know how to communicate with your client to get all the information necessary before you can begin programming. If not, downstream changes can put a serious delay on the project from things not hashed out beforehand. Thanks!

• jQuery does not execute on dynamically loaded content,, even on a click events.

  - by sxv

  I have two document.ready functions. The first loads content into div#header. The second one performs a hide function and then a toggle function on the newly loaded content. I am not sure if this is a queueing issue or something, but not even the alert() below is executed when I click the loaded content. Thanks. <script type="text/javascript"> $(document).ready(function() { $("#header").load("/documents/collegeradioheader.txt"); }); </script> <script type="text/javascript"> $(document).ready(function() { $(".hideme").hide(); $(".slick-toggle").click(function() { alert('hi'); $(this).parent().next('div').slideToggle('fast'); .siblings('div:visible').slideUp('fast'); }); }); </script>

• Delete files in C# that windows does not want me to delete?

  - by user315881

  At my company, we are writing a script to take care of simple tasks that we usually would do by hand. I am using c# to delete profiles in c:\documents and settings\, except a few. These will simply be left alone. The problem is that even with code that sets the files to normal and marks the admin user as an owner, they won't delete. They say that the quick launch folder has access denied. I am using a recursive permissions change method and I know that it works. Same thing with file attributes. Why won't it work? How do I fix this?

• Comparing large strings in JavaScript with a hash

  - by user4815162342

  I have a form with a textarea that can contain large amounts of content (say, articles for a blog) edited using one of a number of third party rich text editors. I'm trying to implement something like an autosave feature, which should submit the content through ajax if it's changed. However, I have to work around the fact that some of the editors I have as options don't support an "isdirty" flag, or an "onchange" event which I can use to see if the content has changed since the last save. So, as a workaround, what I'd like to do is keep a copy of the content in a variable (let's call it lastSaveContent), as of the last save, and compare it with the current text when the "autosave" function fires (on a timer) to see if it's different. However, I'm worried about how much memory that could take up with very large documents. Would it be more efficient to store some sort of hash in the lastSaveContent variable, instead of the entire string, and then compare the hash values? If so, can you recommend a good javascript library/jquery plugin that implements an appropriate hash for this requirement?

• Why do we need Web-Api? [closed]

  - by user437973

  I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.
