  • How do I pass a multi-dimensional array as a GET parameter in PHP?

    - by Onema
    I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for the url? if that is the case how? Thank you

  • 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.

  • .bat file to update loopback controller to external ip

    - by cable729
    Okay, so I've figured out how to get my external ip using wget: wget -q -O - http://whatismyip.com/automation/n09230945.asp that outputs the ip to the command console. adding currentip.txt to the end will write it to a text file. But what I want to do is use netsh interface ip set address name="Local Area Connection 2" source=static addr=[WHAT DO I PUT HERE] Also, a way to make the command prompt not flash would be nice too :)

  • How can I find out what the current charset is in C++?

    - by Stef
    How can I find out what the current charset is in C++? In a console application (WinXP) I am getting negative values for some characters (like äöüé) with (int)mystring[a] and this surprises me. I was expecting the values to be between 127 and 256. So is there something like GetCharset() or SetCharset() in c++?

  • 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!

  • JSON image viewer not working in firefox

    - by jarga
    I have tried to find out why JSON is not working in Firefox all over this forum and the internet. It works on tablets, ie, safari. It works on my desktop in firefox. It only does not work after uploading I've tried a few things (commented out), such as mimeType with no solution. I have tried using the $.ajax with no better luck. Firefox had no javascript errors. I'm using jQuery 1.7. Console.log is printing out the data. $(document).ready(function(){ jQuery.support.cors = true; //$.ajaxSetup({ mimeType: "application/json" }); /*$.ajaxSetup({ scriptCharset: "utf-8" , contentType: "application/json; charset=utf-8"}); */ // loading pictures $.getJSON("intro.json?format=json", function(data){ var links = ''; var imageload = ''; var title = ''; console.log(data) $.each(data, function(key, item){ links += ' <a href=' + item.image + '>' + key + '</a>'; imageload += '<img src="' + item.image + ' " />'; title += item.alt; }); $('.introCon').html(imageload); $('.introCon img').hide(); $('.introCon img:last').fadeIn(500); $('.introCon img').fadeIn(1000); rotatePics(2); }); }); function rotatePics(currentPhoto) { var numberOfPhotos = $('.introCon img').length; currentPhoto = currentPhoto % numberOfPhotos; $('.introCon img').eq(currentPhoto).fadeOut( function() { // re-order the z-index $('.introCon img').each(function(i) { $(this).css( 'zIndex', ((numberOfPhotos - i) + currentPhoto) % numberOfPhotos ); }); $(this).show(); setTimeout(function() {rotatePics(++currentPhoto);}, 3000); }); } Here is the simple JSON from a separate file. { "1" : { "image" : "portfolio/chrpic.png", "alt" : "Blah.", "detail": "Quartz"}, "2" : { "image" : "portfolio/mysspic.png", "alt" : "Landing page.", "detail": "Container"}, "3" : { "image" : "portfolio/decode-pic3.png", "alt" : "Decode this.", "detail": "Landing page 2"}, "4" : { "image" : "portfolio/simple-think-pic.png", "alt" : "Simple Think", "detail": "simpilify your life"} }

  • DRY way of calling a method in every rails model

    - by Tim
    Along the same lines as this question, I want to call acts_as_reportable inside every model so I can do one-off manual reports in the console in my dev environment (with a dump of the production data). What's the best way to do this? Putting acts_as_reportable if ENV['RAILS_ENV'] == "development" in every model is getting tedious and isn't very DRY at all. Everyone says monkey patching is the devil, but a mixin seems overkill. Thanks!

  • How can I make Emacs start-up faster?

    - by Colin
    I use Emacs v. 22 (the console version, either remotely with PuTTY or locally with Konsole) as my primary text editor on Linux. It takes a while to load up each time I start it though, probably almost a second, although I never timed it. I tend to open and close Emacs a lot, because I'm more comfortable using the Bash command-line for file/directory manipulation and compiling. How can I speed up the start-up time?
