• Delphi 2010: how to stamp file version in *.pas and increment it on each save w/o CVS/SVN tools?

  - by FractalizeR

  Hello. How do I have in each *.pas file it's version, incrementing on each save in some comment line? I have plenty of files on three PCs and I need to have a possibility to quickly check their versions against each other. This problem is easily solved by some centralized version control, but some sources I have cannot be trusted to external servers and are kept on TrueCrypt volumes. May be some addon can do that for me? Something like changing $Version: to $Version: 121212 on each save, incrementing this value? May be there is another way also of solving this problem?

• How to programmatically fill a database

  - by Dwaine Bailey

  Hi There, I currently have an iPhone app that reads data from an external XML file at start-up, and then writes this data to the database (it only reads/writes data that the user's app has not seen before, though) My concern is that there is going to be a back catalogue of data of several years, and that the first time the user runs the app it will have to read this in and be atrociously slow. Our proposed solution is to include this data "pre-built" into the applications database, so that it doesn't have to load in the archival data on first-load - that is already in the app when they purchase it. My question is whether there is a way to automatically populate this data with data from, say, an XML file or something. The database is in SQLite. I would populate it by hand, but obviously this will take a very long time, so I was just wondering if anybody had a more...programmatic solution...

• What's the smartest way to organize SVN for translated versions of the same project?

  - by brandonjp

  I apologize because I know this has been covered over and over again, but I'm trying to understand the smartest way to cleverly use subversion to our benefit. (*Note: I know our method is not the BEST way to handle localized versions, but external factors are forcing us to work this way on current projects) We have a fairly static website in English...html, css, js, etc. After the site comes back from the translator we will have 5 variations of the same code (this week...then potentially 25 more in the future!). So we'll soon have a folder for EN, FR, SP, DE, etc. Most files (css, js, img) will remain exactly the same; and html files (structure, id's, classes) will only vary based on the localized text inside the elements. Is there any way to use clever SVN folder structuring that would help us out in the event that if a small change is needed, we don't have to manually change the files in each and every translated version of the site? Thanks! --bp

• Using MSpec runner in Visual Studio 2010 and .NET 4

  - by spapaseit

  Hi Everyone, I'm a big fan of MSpec so naturally I wanted to use is right away with VS2010 as well. I have the MSpec runner defined as an external tool in Visual Studio to be able to have it always visible as a toolbar item. Anyway, whenever I try to use the MSpec runner (mspec.exe) with a .NET 4.0 solution I get the following error: Could not load file or assembly 'file:///C:\Users\[SOMEUSER]\[SOME_FOLDERS}\bin\Debug\[PROJECT].Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. I can still run my specs with the Resharper 5 runner so it's no big drama, but I bothers me to no end :þ Do you guys have any idea what the problem could be? Is there any solution other than recompiling the whole Mspec source code as a .NET 4.0 solution, which I really, really don't want to do? Thanks in advance. Sergi

• Do you chat online for work purposes?

  - by JBB

  I've worked with folks who are chatting online with their peers, constantly batting around ideas. I've also worked with folks who adamantly refuse and think it's a waste of time. Are online live chatting forums of particular use to you? Why or why not? Internal to your company, or external and world-wide? Does your employer encourage or discourage their use? Update: I see some people are voting this question down, yet so far all the answers have been positive, if with some reservations. If someone has a strong negative opinion (I hate online chatting and think it should be banned etc.) I'd really like to hear why.

• Stub web calls in Scala

  - by Dennis Laumen

  I'm currently writing a wrapper of the Spotify Metadata API to learn Scala. Everything's fine and dandy but I'd like to unit test the code. To properly do this I'll need to stub the Spotify API and get consistent return values (stuff like popularity of tracks changes very frequently). Does anybody know how to stub web calls in Scala, the JVM in general or by using some external tool I could hook up into my Maven setup? PS I'm basically looking for something like Ruby's FakeWeb... Thanks in advance!

• SVN Externals in a different SCM

  - by Sean Chambers

  At a previous workplace we used svn externals to update dependent projects when a shared component was updated. This made it easy to see anything that those changes broke, as well as update dependent projects to the latest version of a shared component automatically without any intervention. At a new workplace we are using cc.net with surround scm and I'm trying to find something similar in surround. I haven't found anything like externals, only "shared files", but unlike externals, the shared files doesn't allow you to point at a specific revision of a file for the external. I'm interested in what other people are doing in these scenarios to lean on their continuous integration and treat it more for integration than a "continuous build" server. Does anyone know of a tool or something to do "externals" behavior without using svn? I suppose having an xml registry file of which projects depend on which assemblies and if they should be using the latest version but this seems like overkill.

• Wordpress Trackbacks Not Being Applied

  - by Dustin Digmann

  I am using Wordpress 2.9.1. I recently noticed the trackbacks are not being sent - internal or external. I see two issues I would like to solve. 1) My site has a default, global ping hub which it should notify. This value is not being set into the 'to_ping' value in the *_post table. 2) When I manually enter a trackback in the post, I notice the 'to_ping' value is properly set. It never sends the ping though. The 'pinged' value is always empty. With older versions of WP, this seemed to work automatically.

• What are the virtues of using XML comments in .NET?

  - by Michal Czardybon

  I can't understand the virtues of using XML comments. I know they can be converted into nice documentation external to the code, but the same can be achieved with the much more concise DOxygen syntax. In my opinion the XML comments are wrong, because: They obfuscate the comments and the code in general. (They are more difficult to read by humans). Less code can be viewed on a single screen, because "summary" and "/summary" take additional lines. They suggest that all method parameters have to be commented, whereas 90% of them are obvious and SHOULD be left not commented. The only problem I have with this is that my point of view seems to be in minority. Why?

• How to convert a DOM node list to an array in Javascript?

  - by Guss

  I have a Javascript function that accepts a list of HTML nodes, but it expects a Javascript array (it runs some Array methods on that) and I want to feed it the output of Document.getElementsByTagName that returns a DOM node list. Initially I thought of using something simple like: Array.prototype.slice.call(list,0) And that works fine in all browsers, except of course Internet Explorer which returns the error "JScript object expected", as apparently the DOM node list returned by Document.getElement* methods is not a JScript object enough to be the target of a function call. Caveats: I don't mind writing Internet Explorer specific code, but I'm not allowed to use any Javascript libraries such as JQuery because I'm writing a widget to be embedded into 3rd party web site, and I cannot load external libraries that will create conflict for the clients. My last ditch effort is to iterate over the DOM node list and create an array myself, but is there a nicer way to do that?

• Microsoft JScript runtime error: Object required

  - by Nani

  I wrote a simple javascript function for validating to fields in a aspx page function validate() { if (document.getElementById("<%=tbName.ClientID%>").value=="") { alert("Name Feild can not be blank"); document.getElementById("<%=tbName.ClientID%>").focus(); return false; } if (document.getElementById("<%=ddlBranch.ClientID%>").value=="SelectBranch") { alert("Branch Should Be Selected"); document.getElementById("<%=ddlBranch.ClientID%>").focus(); return false; } } Everything worked fine. Later I linked it to aspx page like a external js file. Now its giving error "Microsoft JScript runtime error: Object required". I'm unable to know where I went wrong.

• Is there any user-friendly way to deliver an In-app purchase subscription to multiple devices?

  - by mkvakin

  Hi everybody, Apple requires an in-app purchase subscription purchased on one device to be available on all devices associated with the user: “...subscriptions must be provided on all devices associated with a user. In App Purchase expects subscriptions to be delivered through an external server that you will provide. You must provide infrastructure to deliver subscriptions to multiple devices.” Is there any way to propagate a subscription to another device transparently without user having to create a server side user account and log in each time he needs to enable the subscription on another device? E.g. by reading a username from some kind of API and using it as a key on a server to store information about subscriptions. I tried to find an API for retrieving user account info but couldn't find any.

• Overriding PEAR error handler

  - by Rolf

  Hi everyone, I'm currently working on an application that requires lots of external libraries. My job right now is set a unique error handler that will manage every error. So far, I found 7 different types of PEAR errors: PEAR_ERROR_RETURN: PEAR_ERROR_EXCEPTION: PEAR_ERROR_CALLBACK: PEAR_ERROR_EXCEPTION: PEAR_ERROR_PRINT: PEAR_ERROR_TRIGGER: PEAR_ERROR_DIE: I want to handle only the serious error (like the native E*_ERROR). The only problem is I have absolutely no idea about PEAR error criticity ! Those names are more related to the way of handling them than to their seriousness... Is there a real documentation about it ? I guess a better solution would consist in using their pushErrorHandling, but I just don't understand how to use it... If someone here knows, I'd be grateful... Thanks in advance !

• Is a class that is hard to unit test badly designed?

  - by Extrakun

  I am now doing unit testing on an application which was written over the year, before I started to do unit-testing diligently. I realized that the classes I wrote are hard to unit test, for the following reasons: Relies on loading data from database. Which means I have to setup a row in the table just to run the unit test (and I am not testing database capabilities). Requires a lot of other external classes just to get the class I am testing to its initial state. On the whole, there don't seem to be anything wrong with the design except that it is too tightly coupled (which by itself is a bad thing). I figure that if I have written automated test cases with each of the class, hence ensuring that I don't heap extra dependencies or coupling for the class to work, the class might be better designed. Does this reason holds water? What are your experiences?

• Regex: absolute url to relative url (C#)

  - by splatto

  I need a regex to run against strings like the one below that will convert absolute paths to relative paths under certain conditions. <p>This website is <strong>really great</strong> and people love it <img alt="" src="http://localhost:1379/Content/js/fckeditor/editor/images/smiley/msn/teeth_smile.gif" /></p> Rules: - If the url contains "/Content/" I would like to get the relative path - If the url does not contain "/Content/", it is an external file, and the absolute path should remain Regex unfortunatley is not my forte, and this is too advanced for me at this point. If anyone can offer some tips I'd appreciate it. Thanks in advance.

• Directly embedding JPEGs in an HTML file

  - by roygbiv

  I can embed a mime encoded JPEG in an html page by saving the page from IE using the File-SaveAs menu and selecting (Web Archive, single file (*.mht)). Renaming this .mht file with .eml enables Outlook to open it and send an HTML email. My questions are: How can I embed JPEG images directly in HTML pages (no external files). Are the images just mime encoded inline in the HTML? It appears that this is IE specific. Do any other browsers support this functionality?

• windows C system call with spaces in command

  - by myforwik

  I cannot make system calls with spaces in the names and parameters. For example: system("c:\program files\something\example.exe c:\my files\example.txt"); I have tried escaping in every way I know how, and NOTHING works. I have tried: system("\"c:\program files\something\example.exe\" \"c:\my files\example.txt\""); and system("c:\program^ files\something\example.exe c:\my^ files\example.txt"); Neither work. I still get 'c:\program' is not a recongnised internal or external command This is really driving me mad... I need to call and pass parameters that have spaces in them. I cannot use the short notation for reasons I won't go into. I have tried with ' quotes instead of " quotes, still doesn't work. I have tried putting quotes around the whole thing and quotes around the spaces and that doesn't work. Does anyone know how to do it properly?

• How can I convert arbitrary strings to CLS-Compliant names?

  - by Brian Hinchey

  Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

• Flash CS5 projects panel totally gone?

  - by Jesse

  So, I popped open up Flash CS5 just now, and I couldn't find my projects panel. I was working on a dual screen set up previously, so my windows were everywhere anyways (sans external). I switched over to a smaller screen workspace, and popped opened the projects panel. Oddly enough, the code snippets panel came up instead. So, I switched off the code snippets, and tried again. I've been trying different ways of opening this panel for about 15 minutes, and I'm totally stumped. Some thorough googling didn't present any relevant results, so, StackOverflow, I turn to you. Is this a known issue? is there a secret backdoor way to open this panel? Am I totally missing something?

• Limiting the maximum number of concurrent requests django/apache

  - by Johan

  Hi, I have a django site that demonstrates the usage of a tool. One of my views takes a file as input and runs some fairly heavy computation trough an external python script and returns some output to the user. The tool runs fast enough to return the output in the same request though. I would however want to limit how many concurrent requests to this URL/view to keep the server from getting congested. Any tips on how i would go about doing this? The page in itself is very simple and the usage will be low.

• How do I display data in a table and allow users to copy selected data?

  - by cfouche

  Hi I have a long list of data that I want to display in table format to users. The data changes when the user performs certain actions in my app, but it is not directly editable. So the user can create a reasonably big table of data, but he can't change individual cells' values. However, I do want the data to be copy-able. So I want it to be possible for the user to select some or all of the cells, and do a ctrl-C to copy the data to his clipboard, and then a ctrl-V to paste the data to an external text editor. At the moment, I'm displaying the data in a ListView with a GridView and this works perfectly, except that GridView doesn't allow one to copy data. What other options can I try? Ours is a WPF app, coding in c#.

• How to make Universal Feed Parser only parse feeds?

  - by piquadrat

  I'm trying to get content from external feeds on my Django web site with Universal Feed Parser. I want to have some user error handling, e.g. if the user supplies a URL that is not a feed. When I tried how feedparser responds to faulty input, I was surprised to see that feedparser does not throw any Exceptions at all. E.g. on HTML content, it tries to parse some information from the HTML code, and on non-existing domains, it returns a mostly empty dictionary: {'bozo': 1, 'bozo_exception': URLError(gaierror(-2, 'Name or service not known'),), 'encoding': 'utf-8', 'entries': [], 'feed': {}, 'version': None} Other faulty input manifest themselves in the status_code or the namespaces values in the returned dictionary. So, what's the best approach to have sane error checking without resorting to an endless cascade of if .. elif .. elif ...?
