  • Can I use the emacs keyboard macro counter as a command prefix?

    - by Sean M
    I'm working on a project in emacs where I'd like to use a keyboard macro that changes slightly with each iteration. When I saw the keyboard macro counter in the manual, that looked like exactly what I needed - but as far as I can tell, that inserts an incrementing number into the current buffer. I want to use an incrementing number as a prefix to another command. For example, instead of inserting 3 into the buffer on the third execution of the macro, I'd like to be able to execute C-u 3 M-x my-command, followed by C-u 4 M-x my-command on the next iteration. Is there way to create a keyboard macro that does this? My specific task is "zipping" two blocks of text in the same buffer together, but even if there's an alternative way to do that specific thing, it'd be good to know the answer to the general question.

  • converting a UTC time to a local time zone in Java

    - by aloo
    I know this subject has been beaten to death but after searching for a few hours to this problem I had to ask. My Problem: do calculations on dates on a server based on the current time zone of a client app (iphone). The client app tells the server, in seconds, how far away its time zone is away from GMT. I would like to then use this information to do computation on dates in the server. The dates on the server are all stored as UTC time. So I would like to get the HOUR of a UTC Date object after it has been converted to this local time zone. My current attempt: int hours = (int) Math.floor(secondsFromGMT / (60.0 * 60.0)); int mins = (int) Math.floor((secondsFromGMT - (hours * 60.0 * 60.0)) / 60.0); String sign = hours > 0 ? "+" : "-"; Calendar now = Calendar.getInstance(); TimeZone t = TimeZone.getTimeZone("GMT" + sign + hours + ":" + mins); now.setTimeZone(t); now.setTime(someDateTimeObject); int hourOfDay = now.get(Calendar.HOUR_OF_DAY); The variables hour and mins represent the hour and mins the local time zone is away from GMT. After debugging this code - the variables hour, mins and sign are correct. The problem is hourOfDay does not return the correct hour - it is returning the hour as of UTC time and not local time. Ideas?

  • how to return NULL for double function with Intel C compiler?

    - by Derek
    I have some code that I am porting from an SGI system using the MIPS compiler. It has functions that are declared to have double return type. If the function can't find the right double, those functions return "NULL" The intel C compiler does not like this, but I was trying to see if there is a compiler option to enable this "feature" so that I can compile without changing code. I checked the man page, and can't seem to find it. Thanks

  • What would be my best MySQL Synchronization method?

    - by Kerry
    We're moving a social media service to be on separate data centers with global load balancing, as our other hosting provider's entire data center went down. Twice. This means that both websites need to be synchronized in some sense -- I'm less worried about the code of the pages, that's easy enough to sync, but they need to have the same database data. From my research on SO, it seems MySQL Replication is a good option, but the MySQL manual, for scaling out, says that its best when there are far more reads then there are writes/updates: http://dev.mysql.com/doc/refman/5.0/en/replication-solutions-scaleout.html In our case, it's about equal. We're getting around 200-300 thousand requests a day right now, and we can grow rapidly. Every request is both a read and write request. What would be the best method or tool to handle this?

  • C# Automatic Properties - Still null after +=?

    - by Sam Schutte
    This seems like a bug to me... I accept that automatic properties, defined as such: public decimal? Total { get; set; } Will be null when they are first accessed. They haven't been initialized, so of course they are null. But, even after setting their value through +=, this decimal? still remains null. So after: Total += 8; Total is still null. How can this be correct? I understand that it's doing a (null + 8), but seems strange that it doesn't pick up that it means it should just be set to 8... Addendums: I made the "null + 8" point in my question - but notice that it works with strings. So, it does null + "hello" just fine, and returns "hello". Therefore, behind the scenes, it is initializing the string to a string object with the value of "hello". The behavior should be the same for the other types, IMO. It might be because a string can accept a null as a value, but still, a null string is not an initialized object, correct? Perhaps it's just because a string isn't a nullable...

  • How do I set a resource file to non-embedded

    - by themaninthesuitcase
    In Visual studio 2008 is it possible to have a resource file that is included as a separate file after compilation rather than as an embedded resource. This is to enable small changes to be rolled out more easily. I have tried build options of Resource, None, Compile and also copy local on and off for most of these. However when ever I try access the resource at run time I get a cannot find resource exception. Is this actually possible or am I wasting my time?

  • Passing GPS speed via the Eclipse Emulator Control

    - by Nick
    Hi, my app queries the GPS-speed using .getSpeed() on a LocationListener. Is there a way to set this speed using the Eclipse Emulator Control or the command line? I tried to feed multiple sets of coordinates to the emulator via the manual GPS-control, but it didn't pick up a speed from that. Also, using a pre-defined GPX-file and playing it doesn't work for me. I would like to test my app without having to take it on a test-drive in my car every time ;)! Thanks!

  • I can't seem to get my grand Total to calculate correctly

    - by Kenny
    When I run this query below, SELECT clientid, CASE WHEN D.ccode = '-1' Then 'Did Not Show' ELSE D.ccode End ccode, ca, ot, bw, cshT, dc, dte, approv FROM dbo.emC D WHERE year(dte) = year(getdate()) I get the correct results. It is correct result because ccode shows 'Did Not Show' when the value on the db is '-1' However, when I do a UNION ALL so I can get total for each column, I get the results but then 'Did Not Show' is no longer visible when valye for ccode is '-1'. There are over 1000 records with valuye of '-1'. Can someone please help? Here is the entire code with UNION.

  • iPhone: Same Rows Repeated in Each Section of Grouped UITableview

    - by Rank Beginner
    I have an app that is a list of tasks, like a to do list. The user configures the tasks and that goes to the SQLite db. The list is displayed in a tableview. The SQL table in question consists of a taskid int, groupname varchar, taskname varchar, lastcompleted datetime, nextdue datetime, weighting integer. I currently have it working by creating an array from each column in the SQL table. In the tableView:cellForRowAtIndexPath: method, I create the controls for each task by binding their values to the array for each column. I want to add configurable task groups that should display as the section titles. I got the task groups to display as the section headers. My problem is that all the task rows are repeated in each group under each header. How do I get the correct rows to show up only under the correct section? I'm really new to development period and took on a hobby of trying to teach myself how to develop iphone apps. So, pretty please, be a little more detailed than you normally would with a professional developer. :)

  • Recommended place for pre-translated Zend Framework resources

    - by Exception e
    Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?

  • What exactly is saved in SQL Server Statistics? When they get updated? Is SQL Server itself is taking care of them?

    - by Pritesh
    I have been working with SQL Server as a Developer a while. One thing I learnt is SQL Server manages Statistics which help Engine to create optimized execution plan. I could not figure out what exactly is stores in Statistics? (I read it saves Vector, but what Vector?) When/In which scenario SQL Server updates Statistics? How/why some time they go out of sync (old Statistics) In case of old Statistics is a manual DBA/Developer intervention is required or SQL Server Will get them updated. As a DBA/Developer how to find out if Statistics OLD? What should we do?

  • php Checking if value exists in array of array

    - by Mark
    I have an array within an array. $a = array ( 0 => array ( 'value' => 'America', ), 1 => array ( 'value' => 'England', ), ) How do I check if 'America' exists in the array? The America array could be any key, and there could be any number of subarrays, so a generalized solution please. Looking on the php manual I see in_array, but that only works for the top layer. so something like in_array("America", $a) would not work. Thanks.

  • Breaking up large DataGridView for printing

    - by Hal
    Hey, I've got a single-row, 40 column-long DataGridView that i need to print. Since i can neither print it directly (because A4 sheets won't cut it ;)) nor adjust its width to the width of the page itself (because the headers look terrible), i wanted to break the DataGridView to 4 separate pieces and display 10 columns per row (imagine: column 1 to 10 in the first line, column 11 to 21 four or five lines below, etc...). Is there an easy way to do this? I was leaning towards a more manual approach (using fors), but i'd love to know if there's a more elegant way. Cheers

Can anyone point me to what I am doing wrong? <html> <head> <title>Test</title> </head> <body> <div class="items"> </div> <script type="text/javascript"> var quizXML = '<quiz><Sporsmal tekst="bla bla bla"/><alternativer><tekst>bla</tekst><tekst>bli</tekst><tekst correct="yes">ble</tekst></alternativer><Sporsmal tekst="More blah"/><alternativer><tekst>bla bla</tekst><tekst correct="yes">bli bli</tekst><tekst>ble ble</tekst></alternativer></quiz>' var quizDOM = $.xmlDOM( quizXML ); quizDOM.find('quiz > Sporsmal').each(function() { var sporsmalTekst = $(this).attr('tekst'); var qDiv = $("<div />") .addClass("item") .addClass("sporsmal") .appendTo($(".spmArr")); var sTekst = $("<h2/>") .html(sporsmalTekst) .appendTo(qDiv); } </script> </body> </html> When I try this in my browser the classes and div are not being created. And the page is just blank. Am i doing something wrong when I intialize the xml?

  • Authentication and Security in my website - need advice please.

    - by Ichirichi
    Hi, I am using database with a list of username/passwords, and a simple web form that allows for users to enter their username/password. When they submit the page, I simply do a stored procedure check to authenticate. If they are authorised, then their user details (e.g. username, dob, address, company address, other important info) are stored in a custom User object and then in a session. This custom User object that I created is used throughout the web application, and also in a sub-site (session sharing). My question/problems are: Is my method of authentication the correct way to do things? I find users complaining that their session have expired although they "were not idle", possibly due the app pool recycling? They type large amounts of text and find that their session had expired and thus lose all the text typed in. I am uncertain whether the session does really reset sporadically but will Forms Authentication using cookies/cookiless resolve the issue? Alternatively should I build and store the User Object in a session, cookie or something else instead in order to be more "correct" and avoid cases like in point #2. If I go down the Forms Authentication route, I believe I cannot store my custom User object in a Forms Authentication cookie so does it mean I would store the UserID and then recreate the user object on every page? Would this not be a huge increase on the server load? Advice and answers much appreciated. L

For instance, I'd like to enable/disable syncing of a Gmail account from my app, without the user having to do anything. I took a look at AccountManager, but that doesn't seem to be the right place to look.
