  • ruby Test::Unit Command line options?

    - by Joe Soul-bringer
    Hi all, When running tests in Ruby's unit::test framework, is there a really easy way to specify, from the command-line, that only one test should be run (that is, specify the test class and test member variable)? If not, is there another framework that has this feature?

  • an emacs command to open a new instance of emacs

    - by RamyenHead
    How can I make a cross-platform emacs command that opens another instance of emacs with -q option? The reason why I need such a command is that it would be easy to modify the command to make it open another instance of emacs with -q and -l option so that the new instance loads an el file that I am editing with the old instance.

  • Java Thread Management and Application Flow

    - by user119179
    I have a Java application that downloads information (Entities) from our server. I use a Download thread to download the data. The flow of the download process is as follows: Log in - The user entity is downloaded Based on the User Entity, download a 'Community' entities List and Display in drop down Based on Community drop down selection, Download and show 'Org Tree' in a JTree Based on Node selection, download Category entities and display in drop down Based on Category selection, download Sub Category entities and display in drop down Based on Sub Category selection download a large data set and save it The download occurs in a thread so the GUI does not 'freeze'. It also allows me to update a Progress Bar. I need help with managing this process. The main problem is when I download entity data I have to find a way to wait for the thread to finish before attempting to get the entity and move to the next step in the app flow. So far I have used a modal dialog to control flow. I start the thread, pop up a modal and then dispose of the modal when the thread is finished. The modal/thread are Observer/Observable the thread does a set changed when it is finished and the dialog disposes. Displaying a modal effectively stops the flow of the application so it can wait for the download to finish. I also tried just moving all the work flow to Observers. All relevant GUI in the process are Observers. Each update method waits for the download to finish and then calls the next piece of GUI which does its own downloading. So far I found these two methods produce code that is hard to follow. I would like to 'centralize' this work flow so other developers are not pulling out their hair when they try to follow it. My Question is: Do you have any suggestions/examples where a work flow such as this can be managed in a way that produces code that is easy to follow? I know 'easy' is a relative term and I know my both my options already work but I would like to get some ideas from other coders while I still have time to change it. Thank you very much.

  • Centering a percent-based div

    - by Sarfraz
    Hello, Recently, a client asked that his site be percent-based rather than pixel-based. The percent was to be set to 80%. As you guys know, it is very easy to center the container if it is pixel-based but how do you center a percent-based main container? #container { width:80%; margin:0px auto; } That does not center the container :(

  • Android JARSIGNER GUI tool?

    - by BahaiResearch.com
    Newbie question. After I have written the Android App (easy part) I need to sign it and upload it (seems the hard part) Is there an Open Source app or tool that I can use to do this so that I don't have to write command shell scripts. JARSIGNER looks overly complex. I'm looking for a dead simple Sign-And-Package up tool. I am using Eclipse with the Android plug in.

  • Invoking cl.exe (MSVC compiler) in Cygwin shell

    - by barcarole
    I'm heavily using Cygwin (with Putty shell). But, it's quite tricky to invoke cl.exe (i.e., Visual C++ compiler toolchain) in the Cygwin bash shell. Running vcvars*.bat in the bash shell doesn't work obviously. I tried to migrate VC++'s environment variables to Cygwin, but it's not that easy. Is there anyone who ever tried to run VC++ compiler in Cygwin bash shell? Thanks, JJ

  • How to check if a field is an Image field

    - by AJ
    Hello, This might seem an easy question for some, but I am struggling with it. I am trying to use SQLDataReader.GetFieldType to check if a certain field is an Image field. Lets assume the first field of the result set is an Image field, if I do: reader.GetFieldType(0).ToString; I get System.Byte[] But is this the correct way to check for it? I really don't like: if (reader.GetFieldType(0).ToString="System.Byte[]") Is there a better way? Thanks, AJ

  • Hosting Microsoft Office application inside Silverlight 4?

    - by Ivan Zlatanov
    I know that Silverlight 4 has the support for COM interop via the AutomationFactory class. dynamic excel = AutomationFactory.CreateObject( "Excel.Application" ); excel.Visible = true; Easy. But this creates a separate process for the COM object. What I am missing here is if I am actually able to actually host the office document inside my silverlight application - in a ContentPresenter for example? Thanks in advance.
