  • Visual Studio not recognizing "BuildStep"

    - by AmbiguousX
    I'm trying to add an automatic post-build trigger to run NDepend after an automated team build in TFS 2010. NDepend's website provided code for integrating this capability, and so I have pasted their code into my .csproj file where they said for it to go, but I receive errors on the build. The errors refer to two of the three "BuildStep" tags I have in the code snippet. The following two snippets are giving me errors: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> and <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> However, this code snippet is NOT throwing up any problems: <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> I just don't understand why one works fine and a nearly identically laid out BuildStep tag does not. Is there something simple that I'm just overlooking? EDIT: Here is how it looks all together, if this makes a difference: <Target Name="NDepend" > <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionDir)MyProject.ndproj</NDProject> <NDOut>$(TargetDir)NDepend</NDOut> <NDIn>$(TargetDir)</NDIn> </PropertyGroup> <Exec Command='"$(NDPath)" "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> </Target> <Target Name="AfterBuild"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Message="Running NDepend analysis"> <Output TaskParameter="Id" PropertyName="StepId" /> </BuildStep> <PropertyGroup> <NDPath>c:\tools\NDepend\NDepend.console.exe</NDPath> <NDProject>$(SolutionRoot)\Main\src\MyProject.ndproj</NDProject> <NDOut>$(BinariesRoot)\NDepend</NDOut> <NDIn>$(BinariesRoot)\Release</NDIn> </PropertyGroup> <Exec Command='$(NDPath) "$(NDProject)" /OutDir "$(NDOut)" /InDirs "$(NDIn)"'/> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Succeeded" /> <OnError ExecuteTargets="MarkBuildStepAsFailed" /> </Target> <Target Name="MarkBuildStepAsFailed"> <BuildStep TeamFoundationServerUrl="$(TeamFoundationServerUrl)" BuildUri="$(BuildUri)" Id="$(StepId)" Status="Failed" /> </Target> EDIT: Added a bounty because I really need to get this going for my team. Thank you in advance!

    - by RichieH
    I'm having trouble retrieving an echoed ajax response through SWFupload.

  • Visual Studio 2010 Database Project does not understand Schema Names anymore?

    - by Xenan
    I just tried to upgrade a Visual Studio 2008 Database project to VS2010 and actually it is quite a mess. Hundreds of warnings, all unsolved references. It seems to boil down to Visual Studio not to understand Schema Names (aka Ownership) anymore. For example, the standard dbo schema: [$(MyDataBase)].dbo.MyTable is fine but: [$(MyDataBase)].myschema.MyTable gives an unsolved reference. It did work in VS2008. Also the abbreviation for dbo, the double dot: [$(MyDataBase)]..MyTable Doesn't work anymore. In the project property windows I restored the references to the correct servers (which were lost after the conversion) but that didn't help. This seems pretty basic but I don't have a clue how to solve this. Any help is appreciated.

  • user height and weight in sql

    - by Samuel
    We are planning to capture a user's height and weight and am looking for ideas on representing them in sql. I have the following questions in mind weight can be expressed in kilograms and grams and height in meters and centimeters, so should I capture them as a BigDecimal with an appropriate precision and scale or capture them as vanilla strings and do the manipulation in the user interface. Note: I am planning to capture the kilograms and grams separately in the user interface. should the metric of measurement be part of the sql (i.e. the end user might want to view this information in pounds, inches according to his preference) OR Should I just support kilograms / meters in the database and do the conversion while showing this in the user interface

  • Excel Worksheet assignment in VB.Net doesn't compile

    - by Brian Hooper
    I'm converting a VB6 application into VB.Net and having trouble with the basics. I start off with:- Dim xl As Excel.Application Dim xlsheet As Excel.Worksheet Dim xlwbook As Excel.Workbook xl = New Excel.Application xlwbook = xl.Workbooks.Open(my_data.file_name) xlsheet = xlwbook.Sheets(1) but the last line doesn't compile; it reports Option Strict On disallows implicit conversion from 'Object' to 'Microsoft.Office.Interop.Excel.Worksheet' I can make this go away by replacing the line with xlsheet = CType(xlwbook.Sheets(1), Excel.Worksheet) but that does't look like the right thing to do to me. If the assignment is correct, I would have thought the object should naturally have the correct type. So: does anyone know what the correct thing I should be doing here?

  • Variables variable and inheritance

    - by Xack
    I made code like this: class Object { function __get($name){ if(isset($this->{$name})){ return $this->{$name}; } else { return null; } } function __set($name, $value){ $this->{$name} = $value; } } If I extend this class (I don't want to repeat this code every time), it says "Undefined variable". Is there any way to do it?

  • how to convert webpage apostrophe (&#8217;) to ascii 39 in ruby 1.8.7

    - by maninwarren
    That's pretty much it. I'm using Nokogiri to scrape a web page what has ’ ; characters in it, and I can't figure out how to do the conversion. here's what I tried: str.gsub(/&#8217;/,"'") str.gsub("&#8217;","'") str.gsub("GÇÖ","'") # that's how it looks when I do a puts (In the above, there's no space between the ’ and the ";", but if I don't put the space in, SO converts it to an apostrophe -- the cruel, cruel irony!) I'm sure this is covered somewhere, but couldn't find the solution here or on the web. TIA

  • How can I get the same strstream functionality now that's deprecated?

    - by chila
    I use to write code like this: void fun(char *buff, unsigned size) { std::strstream str(buff, size); str << "hello world: " << 5; } so I can use stream output over an arbitrary buffer. I've found this technique both efficient (no allocations) and useful (streams!). Now that std::strstream is deprecated, how can I get the same speed+flexibility that I can get with this code?

  • Ignore first line on csv parse Rails

  • Why is "int + string" possible in statically-typed C# but not in dynamically-typed Python?

    - by Salvador Dali
    While studying C# I found it really strange, that dynamically typed Python will rise an error in the following code: i = 5 print i + " " whereas statically typed C# will normally proceed the similar code: int i = 5; Console.Write(i + " "); I would expect other way around (in python I would be able to do this without any casting, but C# would require me to cast int to string or string to int). Just to highlight, I am not asking what language is better, I am curious what was the reason behind implementing the language this way.

  • How to strip specific contents of a String in Java

    - by user2974877
    So I have a string, and I want to strip out some parts of it using, for example, the firt and last characters of the "interesting" part. String dirty = "$!$!%!%$something interesting&!!$!%$something interesting2"; And the output something like: String clean = "something interesting:something interesting2"; Note: The code needs to work without knowing the random part, changing everytime the program runs. I researched and only found code that does it, but only knowing the random segment.

  • Working with the IE cache from C# & WPF

    - by Eric
    I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

  • iPad web app: Prevent input focus AFTER ajax call

    - by Mike Barwick
    So I've read around and can't for the life of me figure out of to solve my issue effectively. In short, I have a web app built for the iPad - which works as it should. However, I have an Ajax form which also submits as it should. But, after the callback and I clear/reset my form, the "iPad" automatically focuses on an input and opens the keyboard again. This is far from ideal. I managed to hack my way around it, but it's still not perfect. The code below is run on my ajax callback, which works - except there's still a flash of the keyboard quickly opening and closing. Note, my code won't work unless I use setTimeout. Also, from my understanding, document.activeElement.blur(); only works when there's a click event, so I triggered one via js. IN OTHER WORDS, HOW DO I PREVENT THE KEYBOARD FROM REOPENING AFTER AJAX CALL ON WEB APP? PS: Ajax call works fine and doesn't open the keyboard in Safari on the iPad, just web app mode. Here's my code: hideKeyboard: function () { // iOS web app only, iPad IS_IPAD = navigator.userAgent.match(/iPad/i) != null; if (IS_IPAD) { $(window).one('click', function () { document.activeElement.blur(); }); setTimeout(function () { $(window).trigger('click'); }, 500); } } Maybe it's related to how I'm clearing my forms, so here's that code. Note, all inputs have tabindex="-1" as well. clearForm: function () { // text, textarea, etc $('#campaign-form-wrap > form')[0].reset(); // checkboxes $('input[type="checkbox"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.checkbox').removeClass('checked'); // radio inputs $('input[type="radio"]').removeAttr('checked'); $('#campaign-form-wrap > form span.custom.radio').removeClass('checked'); // selects $('form.custom .user-generated-field select').each(function () { var selection = $(this).find('option:first').text(), labelFor = $(this).attr('name'), label = $('[for="' + labelFor + '"]'); label.find('.selection-choice').html(selection); }); optin.hideKeyboard(); }

  • File exists but is unreadable by PHP

    - by Aron
    More than once I have ran into this issue: I have a cache file that is automatically generated by PHP. It contains some generated PHP code. However for some reason the file cannot be read and parsed by PHP. These are the symptoms: File actually exists on file system. Using Terminal you can navigate to the file, view its contents (which are fully intact), etcetc. PHP file_exists() will report that the file exists...which is correct since it does :) Then I include() the file. But when actually parsing the file, PHP will just consider it an empty file. No fatal error, just no PHP code actually executed. Again, its as if the file was completely empty (which I assure you, it is not)... It is not a permissions issue. Permissions are set as needed. Workaround: open the file in Terminal via 'nano' or some other text editor and just save it to the disk again. After that (despite no changes to the content) PHP will run it just fine... As a clarification, I'd like to add that this happens rarely, but frequently enough to be a problem. And even when it does, there are hundreds of other similar files on the same system that work without a problem... If this were an issue affecting only my own scripts, I would consider that there must be a bug in the way I generate the PHP code. But no, the issue has occurred more than once when deploying to a server (usually from Beanstalk repository via FTP). The issue has been present on various servers, Debian and Ubuntu running Zend Community Server. Any ideas? One that crossed my mind was opcode cache-ing (part of Zend Server CE)...could it be that an empty version of the file is cached if it is requested while the write operation is still in progress?
