    $ bc BC> ibase=2 BC> 110&101 // wanna get 100 (standar_in) 8: syntax error Wikipedia informs that the ops are "|, & and ^". It may be that they work only in certain BC-types or I misread something.

  • How do I limit JPQ output?

    - by den-javamaniac
    I need to limit number of entities returned by a query to some certain value inside a JPA query (through JPQL). Particularly: select m from Manual m //constraint e.g. in sql (mysql syntax) I would do it like: select * from Manual limit 1 The only solution that comes up is simply to get all entities and then choose first one, which is out of the issue. Any ideas?

  • Sparse checkouts and svn:externals

    - by JesperE
    I'm trying to do a sparse checkout of a folder containing externals, but none of the externals are being checked out. This issue seems to indicate that this behavior may be by design, or at least that it isn't clear what the behavior should be. From my point of view, the obvious behavior is that externals are treated just as any other directory, and checked out following the same sparse checkout rules. Is there a way to work around this except manually checking out the externals?

  • drupal rules module - add fields to email

    - by bert
    I am looking for the syntax to add node fields to the body of an email. Examples I looked at indicate the the format is: [content_type:content_type_title] However my email arrives with just the string : [content_type:content_type_title] Even better would be a PHP snippet that loads the node and dumps filed title and filed value into the body of the message.

  • ExtJS: Add Single Click Action To A Node In A TreePanel

    - by FluidFoundation
    [revised] I'm creating a TreePanel in ExtJs that is loading its children from a JSON file. I'm having trouble adding a click action to the nodes. I'm not sure whether it's added in the script creating the tree, or if its added as a property in the JSON, and if so, what the syntax would be. Any help would be appreciated! Please provide an example if possible.

    - by Adnan
    I would like to perform checking on the following: VALID LINES; /**/ some code */ some code /** dsfsdkf sd**/ NOT VALID LINES; /**/ //some code */ /***/ //somecode So basically if there is a line of code outside a comment it is valid, otherwise not.

  • How do I get Aptana to recognize .jspf files?

    - by Keith Bentrup
    How do I get Aptana to recognize .jspf files? I'd like to have syntax highlighting for .jspf files. I'm sure there's a preference/config option or an xml file to edit, but I'm not finding it. I assume it's similar to the eclipse process, so I'm tagging eclipse, too. If it's not, I'll remove the tag.

  • Java: JButton actionListener explantation

    - by MrDoctorProfessorTyler
    I am extremely confused as to how a JButton works. I have read over the oracle documents of the JButton, but I have failed to see how a JButton can have an actionlistener added to it. I have really always wondered how things like JFrames and all that can have things like .addMouseListener and all that. Can anyone explain how a JButton can have an actionListener added to it like the .addActionListener(...) syntax?

  • No IO exception reported for socket operation when the interface is removed

    - by user352536
    The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?
