  • Scaffolding Web Services in Grails

    - by Dan
    I need to implement a web app, but instead of using relational database I need to use different SOAP Web Services as a back-end. An important part of application only calls web services and displays the result. Since Web Services are clearly defined in form of Operation: In parameters and Return Type it seems to me that basic GUI could be easily constructed just like in the case of scaffolding based on Domain Entities. For example in case of SearchProducts web service operation I need to enter search parameters as input, so the search page can be constructed. Operation will return a list of products, so I need a page that will display this list in some kind of table. Is there already some library in grails that let you achieve this. If not, how would you go about creating one?

  • ASP.NET Where can I write to without modifying permissions?

    - by LeeW
    Where can I write to without modifying site permissions? I need to store a value on the server that will remain when all sessions have closed and can be re-read when a new session is started. I need to make sure that no site permissions need to be changed so the location can be written to by anonymous users and any authenticated user. Does such a place exist? Thanks Lee

  • C, Cygwin, and compiling drand and srand

    - by Kaytiana
    Hello, I have a C code which I am trying to compile in Cygwin and which contains both the drand() and srand() functions. I had Windows Vista with Cygwin installed and the code seemed to comile fine, but my computer broke and I had to get a new one. The new computer has Windows 7 64-bit version. I had a few issues downloading Cygwin but finally managed to do it by only selecting a few packages and then have been trying to get the rest that I need. The problem is I don't have the help I had installing it on my other computer so I don't know which packages I actually need, so I have just been guessing (all the gcc ones) but I mustn't have the one I need for srand and drand to work. If anyone could point me in the right direction, and also possibly just let me know which packages I need to compile C so I can check I have them all that would be great. Thanks a lot in advance for any help. Sorry, that was a lot of words! Kaytiana

  • How can I merge properties of two JavaScript objects dynamically?

    - by JC Grubbs
    I need to be able to merge two (very simple) JavaScript objects at runtime. For example I'd like to: var obj1 = { food: 'pizza', car: 'ford' } var obj2 = { animal: 'dog' } obj1.merge(obj2); //obj1 now has three properties: food, car, and animal Does anyone have a script for this or know of a built in way to do this? I do not need recursion, and I do not need to merge functions, just methods on flat objects.

  • Prolog - generate correct bracketing

    - by Henrik Bak
    I'd like to get some help in the following exam problem, i have no idea how to do this: Input: a list of numbers, eg.: [1,2,3,4] Output: every possible correct bracketing. Eg.: (in case of input [1,2,3,4]): ((1 2) (3 4)) ((1 (2 3)) 4) (1 ((2 3) 4)) (1 (2 (3 4))) (((1 2) 3) 4) Bracketing here is like a method with two arguments, for example multiplication - then the output is the possible multiplication orders. Please help, i'm stuck with this one. Any help is appreciated, thanks!

  • How do I compile Android Browser (or other android-supplied applications)

    - by afriza
    I want to add support for Arabic (or other languages which are currently unsupported) to the applications supplied by android platform (e.g. Browser) without having root-access. To add Arabic support (at least displaying only) in a normal application (using developer SDK), I will need to: Add fonts Modify (reshape) the characters to be rendered For illustration, if I have string a aaa, I will need to change a aaa into a bcd because letter a at the beginning, middle, and end of a word need to be changed to b,c and d respectively) But now I want to compile android's Browser (and other apps). I am planning to get the source codes for these applications and their dependencies and bundle them as stand-alone applications which do not require root-access, and thus do not void the warranty. Other solutions which void the warranty can be obtained here. My Questions: Is the application's (e.g. Browser's) source code + 'developer SDK' enough to accomplish this? Do I need to get the source code + the development environment for the android platform? Any tips?

  • PostgreSQL - fetch the row which has the Max value for a column

    - by Joshua Berry
    I'm dealing with a Postgres table (called "lives") that contains records with columns for time_stamp, usr_id, transaction_id, and lives_remaining. I need a query that will give me the most recent lives_remaining total for each usr_id There are multiple users (distinct usr_id's) time_stamp is not a unique identifier: sometimes user events (one by row in the table) will occur with the same time_stamp. trans_id is unique only for very small time ranges: over time it repeats remaining_lives (for a given user) can both increase and decrease over time example: time_stamp|lives_remaining|usr_id|trans_id ----------------------------------------- 07:00 | 1 | 1 | 1 09:00 | 4 | 2 | 2 10:00 | 2 | 3 | 3 10:00 | 1 | 2 | 4 11:00 | 4 | 1 | 5 11:00 | 3 | 1 | 6 13:00 | 3 | 3 | 1 As I will need to access other columns of the row with the latest data for each given usr_id, I need a query that gives a result like this: time_stamp|lives_remaining|usr_id|trans_id ----------------------------------------- 11:00 | 3 | 1 | 6 10:00 | 1 | 2 | 4 13:00 | 3 | 3 | 1 As mentioned, each usr_id can gain or lose lives, and sometimes these timestamped events occur so close together that they have the same timestamp! Therefore this query won't work: SELECT b.time_stamp,b.lives_remaining,b.usr_id,b.trans_id FROM (SELECT usr_id, max(time_stamp) AS max_timestamp FROM lives GROUP BY usr_id ORDER BY usr_id) a JOIN lives b ON a.max_timestamp = b.time_stamp Instead, I need to use both time_stamp (first) and trans_id (second) to identify the correct row. I also then need to pass that information from the subquery to the main query that will provide the data for the other columns of the appropriate rows. This is the hacked up query that I've gotten to work: SELECT b.time_stamp,b.lives_remaining,b.usr_id,b.trans_id FROM (SELECT usr_id, max(time_stamp || '*' || trans_id) AS max_timestamp_transid FROM lives GROUP BY usr_id ORDER BY usr_id) a JOIN lives b ON a.max_timestamp_transid = b.time_stamp || '*' || b.trans_id ORDER BY b.usr_id Okay, so this works, but I don't like it. It requires a query within a query, a self join, and it seems to me that it could be much simpler by grabbing the row that MAX found to have the largest timestamp and trans_id. The table "lives" has tens of millions of rows to parse, so I'd like this query to be as fast and efficient as possible. I'm new to RDBM and Postgres in particular, so I know that I need to make effective use of the proper indexes. I'm a bit lost on how to optimize. I found a similar discussion here. Can I perform some type of Postgres equivalent to an Oracle analytic function? Any advice on accessing related column information used by an aggregate function (like MAX), creating indexes, and creating better queries would be much appreciated! P.S. You can use the following to create my example case: create TABLE lives (time_stamp timestamp, lives_remaining integer, usr_id integer, trans_id integer); insert into lives values ('2000-01-01 07:00', 1, 1, 1); insert into lives values ('2000-01-01 09:00', 4, 2, 2); insert into lives values ('2000-01-01 10:00', 2, 3, 3); insert into lives values ('2000-01-01 10:00', 1, 2, 4); insert into lives values ('2000-01-01 11:00', 4, 1, 5); insert into lives values ('2000-01-01 11:00', 3, 1, 6); insert into lives values ('2000-01-01 13:00', 3, 3, 1);

  • What are useful functions for drawing text (MFC)?

    - by kobac
    I'm creating a line chart control, and I need to write (or better say draw) the axis names and axis values.
