  • What would a new web development tool need to succeed?

    - by boost
    If one wanted to bring a new web development tool to market, what would it have to be able to do that would differentiate it enough from all the others to attract people's attention? In what areas are all the other frameworks and languages falling down, such that if a new product addressed those issues, it would stand a chance of being adopted by significant user community?

  • XtraGrid Suite - is there a way to add a button or hyperlink to a cell?

    - by calico-cat
    I'm working with the XtraGrid Suite made by DevExpress. I can't find any sort of functionality to do this, but I'm curious if you can add a button or hyperlink to a grid cell. Context: I've got an Events list. Each Event has a Time, Start/End, and a Category (Utility and Maintenance). There can be Start events and Stop events. Having done my analysis of the problem, I've decided that having a StartTime and EndTime for each event would not work. So if an event starts, I'd record the current time to the Event object, and set it as a 'Start' event. I'd like to add a "Stop" button/hyperlink to a cell in that row. If the user wishes to log an Ends event, the event type, etc would be copied to a new Event with the type 'Stop' and the button would disappear. I hope this makes sense. EDIT: Aaronaught's answer is actually better than what I was originally asking (a button) so I've updated the question. That way, anyone looking for putting a hyperlink in a cell can benefit from his example : )

  • Any suggestions for good automated web load testing tool?

    - by fmunkert
    What are some good automated tools for load testing (stress testing) web applications, that do not use record and replay of HTTP network packets? I am aware that there are numerous load testing tools on the market that record and replay HTTP network packets. But these are unsuitable for my purpose, because of this: The HTTP packet format changes very often in our application (e.g. when we optimize an AJAX call). We do not want to adapt all test scripts just because there is a slight change in HTTP packet format. Our test team shall not need to know any internals about our application to write their test scripts. A tool that replays HTTP packets, however, requires the team to know the format of HTTP requests and responses, such that they can adapt details of the replayed HTTP packets (e.g. user name). The automated load testing tool I am looking for should be able to let the test team write "black box" test scripts such as: Invoke web page at URL http://... . First, enter XXX into text field XXX. Then, press button XXX. Wait until response has been received from web server. Verify that text field XXX now contains the text XXX. The tool should be able to simulate up to several 1000 users, and it should be compatible with web applications using ASP.NET and AJAX.

  • Formatting the output of a custom tool so I can double click an error in Visual Studio and the file opens

    - by Ben Scott
    I've written a command line tool that preprocesses a number of files then compiles them using CodeDom. The tool writes a copyright notice and some progress text to the standard output, then writes any errors from the compilation step using the following format: foreach (var err in results.Errors) { // err is CompilerError var filename = "Path\To\input_file.xprt"; Console.WriteLine(string.Format( "{0} ({1},{2}): {3}{4} ({5})", filename, err.Line, err.Column, err.IsWarning ? "" : "ERROR: ", err.ErrorText, err.ErrorNumber)); } It then writes the number of errors, like "14 errors". This is an example of how the error appears in the console: Path\To\input_file.xrpt (73,28): ERROR: An object reference is required for the non-static field, method, or property 'Some.Object.get' (CS0120) When I run this as a custom tool in VS2008 (by calling it in the post-build event command line of one of my project's assemblies), the errors appear nicely formatted in the Error List, with the correct text in each column. When I roll over the filename the fully qualified path pops up. The line and column are different to the source file because of the preprocessing which is fine. The only thing that stands out is that the Project given in the list is the one that has the post-build event. The problem is that when I double click an error, nothing happens. I would have expected the file to open in the editor. I'm vaugely aware of the Microsoft.VisualStudio.Shell.Interop namespace but I think it should be possible just by writing to the standard output.

  • Free tools versus paid tools.

    - by Dennis Vroegop
    We live in a strange world. Information should be free. Tools should be free. Software should be free (and I mean free as in free beer, not as in free speech). Of course, since I make my living (and pay my mortgage) by writing software I tend to disagree. Or rather: I want to get paid for the things I do in the daytime. Next to that I also spend time on projects I feel are valuable for the community, which I do for free. The reason I can do that is because I get paid enough in the daytime to afford that time. It gives me a good feeling, I help others and it’s fun to do. But the baseline is: I get paid to write software. I am sure this goes for a lot of other developers. We get paid for what we do during the daytime and spend our free time giving back. So why does everyone always make a fuzz when a company suddenly starts to charge for software? To me, this seems like a very reasonable decision. Companies need money: they have staff to pay, buildings to rent, coffee to buy, etc. All of this doesn’t come free so it makes sense that they charge their customers for the things they produce. I know there’s a very big Open Source market out there, where companies give away (parts of) their software and get revenue out of the services they provide. But this doesn’t work if your product doesn’t need services. If you build a great tool that is very easy to use, and you give it away for free you won’t get any money by selling services that no user of your tool really needs. So what do you do? You charge money for your tool. It’s either that or stop developing the tool and turn to other, more profitable projects. Like it or not, that’s simple economics at work. You have something other people want, so you charge them for it. This week it was announced that what I believe is the most used tool for .net developers (besides Visual Studio of course),namely Red Gates .net reflector, will stop being a free tool. They will charge you $35 for the next version. Suddenly twitter was on fire and everyone was mad about it. But why? The tool is downloaded by so many developers that it must be valuable to them. I know of no serious .net developer who hasn’t got it on his or her machine. So apparently the tool gives them something they need. So why do they expect it to be free? There are developers out there maintaining and extending the tool, building new and better versions of it. And the price? $35 doesn’t seem much. If I think of the time the tool saved me the 35 dollars were earned back in a day. If by spending this amount of money I can rely on great software that helps me do my job better and faster, I have no problems by spending it. I know that there is a great team behind it, (the Red Gate tools are a must have when developing SQL systems, for instance), and I do believe they are in their right to charge this. So.. there you have it. This is of course, my opinion. You may think otherwise. Please let me know in the comments what you think! Tags van Technorati: redgate,reflector,opensource

  • gcc 4.5 installation problem under ubuntu

    - by Claire Huang
    I tried to install gcc 4.5 on ubuntu 10.04 but failed. Here is a compile error that I don't know how to solve. Is there anyone successfully install the latest gcc on ubuntu? Following is my steps and the error message, I'd like to know where is the problem.... Step1: download these files: gcc-core-4.5.0.tar.gz gcc-g++-4.5.0.tar.gz gmp-4.3.2.tar.bz2 mpc-0.8.1.tar.gz mpfr-2.4.2.tar.gz Step2: Unzip above files Step3: move gmp, mpc, mpfr to the gcc-4.5.0/ directory. mv gmp-4.3.2 gcc-4.5.0/gmp mv mpc-0.8.1 gcc-4.5.0/mpc mv mpfr-2.4.2 gcc-4.5.0/mpfr Step4: go to gcc-4.5.0 directory and do configuration: sudo ./configure Step5: compile and install sudo make sudo make install The first 4 steps is OK, I can configure it successfully. However, when I try to compile it, following error message comes out, I cannot figure out what the problem is. Should I change the name from "gcc 4.5" to "gcc"?? It's a little strange that we need to do this by ourself. Is there anything I missed during the installation? xxx@xxx-laptop:/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0$ sudo make [sudo] password for xxx: [ -f stage_final ] || echo stage3 > stage_final /bin/bash: line 2: test: /media/Data/Tool/linux/gcc: binary operator expected /bin/bash: /media/Data/Tool/linux/gcc: No such file or directory make[1]: Entering directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make[2]: Entering directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make[3]: Entering directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' rm -f stage_current make[3]: Leaving directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make[2]: Leaving directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make[2]: Entering directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' Configuring stage 1 in host-x86_64-unknown-linux-gnu/intl /bin/bash: /media/Data/Tool/linux/gcc: No such file or directory make[2]: *** [configure-stage1-intl] Error 127 make[2]: Leaving directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/media/Data/Tool/linux/gcc 4.5/gcc-4.5.0' make: *** [all] Error 2

  • Conversion of DVC-PRO HD 1080, any free tool?

    - by Andrea Ambu
    Is there any free (as in beer, and if it's possible as in bird) tool to convert a dvd in the format DVC-PRO HD 1080 to a normal/standard dvd format so that I can play it on a normal DVD player? EDIT: I changed the wording a bit. We've a video in DVC-PRO HD 1080 but as far as I know it is a proprietary format. We'd like to create a standard dvd out of it. I'm not really in video encoding and dvd conversion. I thought I need to be more precise. VLC currently doesn't support DVC-PRO HD 1080.

  • How to get a tool window title bar height in WPF ?

    - by user275587
    WPF includes the title bar height in the total window height instead of using only the client content area height. Is there a way to disable this behaviour? If not, how can I get the height of a tool window title bar? I'm aware of the SystemParameters.CaptionHeight property and the SystemParameters.WindowCaptionHeight property but they both return the height of a regular window title bar. This is not the correct value for a tool window because the title bar is smaller for this type of window. I need something like SystemParameters.ToolWindowCaptionHeight Thanks.

  • Is there a PHP refactoring tool to tell what functions are never called?

    - by ae
    I have a large codebase which has suffered many changes over the years. I would like to remove the functions that are no longer called or relevant. Is there a tool that will analysis the codebase and determine if a method is ever used? I'm also using phpunit/xdebug which reports which functions have not been run for the unit tests, however coverage is only at 55% and will require a massive amount of work to bring it up to 100% (I'm working on it!). Anything that was a command line tool would be extra good as I could hook it into hudson (CI).

  • How do you use any2mobi command line tool (part of Calibre) to make mobi files from HTML?

    - by Paul Chernoch
    I am on MAC OS X 10.5.5. I installed Calibre, a tool for converting e-book files from one format to another. It has a GUI as well as command line tools. I am trying to run the command line tool "any2mobi" to convert HTML files to MOBI pocket format or Kindle AZW format, with a TOC. I get the error "-bash: any2mobi: command not found". Clearly, any2mobi is not in my path. Where is it? I tried searching but came up empty. I installed version 0.6.0b6 of Calibre.

  • Windows 7 / 8 tool for amplifying sound / equivalent to pavucontrol?

    - by Quandary
    I'm watching live streamed videos, but the volume sometimes is barely loud enough. With Windows, I can only turn the system volume and the flash volume up to maximum, and then bad luck if that's still not loud enough. On Linux, on the same notebook, I have the same problem, but I can use pavucontrol to amplify the sound volume beyond 100%. Unfortunately, I can't always work on Linux, since Visual Studio and SQL-Server only run on Windows. Is there any tool or way to amplify volume on Windows 7 / 8 , without having to resort to run Linux in a virtual machine?

  • How to Recover HDD Formatted by "Create a Recovery Drive" Tool of Windows 8.1?

    - by ide
    I have 2 TB USB HDD which had these drives F: about 1 TB with 750 GB data H: about 120 GB with 60 GB data I: about 780 GB with 250 GB data (For TV: It was raw in Windows but visible in the Smart TV) I took 521 MB from last part of H to get new G drive. Then I run "Create a Recovery Drive" tool of Windows 8.1 and chose G drive. It said all data in the drive will be deleted. I thought it is just G drive but it deleted my whole HDD. It created 32 GB new F drive with writing 337 MB on it and rest of HDD is unallocated. I tried these programs to get my first 3 drives but non of them helped for getting 1st partition.

  • Why did Google remove the search box in developer tool from Chrome 22 stable release?

    - by Bruce
    In previous version of Chrome, there's the search box in developer tool, on the right top when I open it, just as shown below. (Sorry I can't upload image cuz' I don't have enough reputation for now.) http://i.minus.com/iklSx2vi0uzFB.JPG But, after I upgraded to the first release of Chrome 22 yesterday, that search box was gone, as shown below. http://i.minus.com/ibxXt9wnBekR7E.JPG It is such a useful search box that I rely on all the time, to search for something, or to validate an xpath. So does Google just 'hide' it somewhere else? Or do they really remove it? Anyone know why they made such changes?

  • Is there a 3 way merger tool that “understands” common refactoring?

    - by Ian Ringrose
    When a simple refactoring like “rename field” has been done on one branch it can be very hard to merge the changes into the other branches. (Extract method is much harder as the merge tools don’t seem to match the unchanged blocks well) Now in my dreams, I am thinking of a tool that can record (or work out) what well defined refactoring operations have been done on one branch and then “replay” them on the other branch, rather than trying to merge every line the refactoring has affected. see also "Is there an intelligent 3rd merge tool that understands VB.NET" for the other half of my pain! Also has anyone try something like MolhadoRef (blog article about MolhadoRef and Refactoring-aware SCM), This is, in theory, refactoring-aware source control.

  • benchmark tcp: ab or iperf like tool to send hex/binary/pcap data?

    - by olan
    Hello all, I have written a server in Twisted for a current project I'm working on, and now I need to test it. It receives TCP packets, with the payload consisting of just a serialised binary string. I want to be able to test the server for concurrency/throughput using the binary data as the payload, but can not find any tool that will allow me to do this. I tried iperf -F but it didn't work, as I think it was sending the binary/hex data as chars. I've also looked at ab which seems to be perfect - if only for http. As well as these, I've had a look at tcpreplay, but it doesn't perform any testing (or establish TCP connections) so it's not much use. Any help would be greatly appreciated as I'm rather stuck on this one!
