  • APE engine Mysql push data to channel on insert

    - by Fotis
    Hello, i am working with APE Engine (http://www.ape-project.org) and up until now i had no actual problem. The problem is that i would like to use the MySQL module and push data to a channel each time a row is inserted into a table. I've tried to setup a server side module, i created an SQL query but data is fetched only when the server boots. How can i make this work?

  • Rectangles Covering

    - by den bardadym
    I have N rectangles with sides parallel Ox and Oy. Exists another rectangele (model). I need create algorithm, which can tell: is model covered by N rectangles? and code him. I have some ideas. First I think need sort rectangles by left side (it can be done by O(n log n)). Then I think need use vertical sweeping line. Thanks.

  • GHC.Generics and Type Families

    - by jberryman
    This is a question related to my module here, and is simplified a bit. It's also related to this previous question, in which I oversimplified my problem and didn't get the answer I was looking for. I hope this isn't too specific, and please change the title if you can think if a better one. Background My module uses a concurrent chan, split into a read side and write side. I use a special class with an associated type synonym to support polymorphic channel "joins": {-# LANGUAGE TypeFamilies #-} class Sources s where type Joined s newJoinedChan :: IO (s, Messages (Joined s)) -- NOT EXPORTED --output and input sides of channel: data Messages a -- NOT EXPORTED data Mailbox a instance Sources (Mailbox a) where type Joined (Mailbox a) = a newJoinedChan = undefined instance (Sources a, Sources b)=> Sources (a,b) where type Joined (a,b) = (Joined a, Joined b) newJoinedChan = undefined -- and so on for tuples of 3,4,5... The code above allows us to do this kind of thing: example = do (mb , msgsA) <- newJoinedChan ((mb1, mb2), msgsB) <- newJoinedChan --say that: msgsA, msgsB :: Messages (Int,Int) --and: mb :: Mailbox (Int,Int) -- mb1,mb2 :: Mailbox Int We have a recursive action called a Behavior that we can run on the messages we pull out of the "read" end of the channel: newtype Behavior a = Behavior (a -> IO (Behavior a)) runBehaviorOn :: Behavior a -> Messages a -> IO () -- NOT EXPORTED This would allow us to run a Behavior (Int,Int) on either of msgsA or msgsB, where in the second case both Ints in the tuple it receives actually came through separate Mailboxes. This is all tied together for the user in the exposed spawn function spawn :: (Sources s) => Behavior (Joined s) -> IO s ...which calls newJoinedChan and runBehaviorOn, and returns the input Sources. What I'd like to do I'd like users to be able to create a Behavior of arbitrary product type (not just tuples) , so for instance we could run a Behavior (Pair Int Int) on the example Messages above. I'd like to do this with GHC.Generics while still having a polymorphic Sources, but can't manage to make it work. spawn :: (Sources s, Generic (Joined s), Rep (Joined s) ~ ??) => Behavior (Joined s) -> IO s The parts of the above example that are actually exposed in the API are the fst of the newJoinedChan action, and Behaviors, so an acceptable solution can modify one or all of runBehaviorOn or the snd of newJoinedChan. I'll also be extending the API above to support sums (not implemented yet) like Behavior (Either a b) so I hoped GHC.Generics would work for me. Questions Is there a way I can extend the API above to support arbitrary Generic a=> Behavior a? If not using GHC's Generics, are there other ways I can get the API I want with minimal end-user pain (i.e. they just have to add a deriving clause to their type)?

  • How to wire a verifier to a 2.0m5 Restlet using the spring extension and an xml config?

    - by Kevin Pauli
    I can't seem to find any example of how to do this. Imperatively in java it would be a piece of cake of course, but I can't seem to figure out how to inject my JaasVerifier into my SpringComponent declaratively from within the xml. It appears from the method signatures that Verifier is designed to be attached to Context, but the instance of Context itself is created as a side effect of the SpringComponent creation so I can't get a hold of it in Spring. There must be something I am missing.

  • USB seems to pause system

    - by Marco van de Voort
    I've an application that does some simple measuring, for which it polls a few 100kbs several times a second (8-25 times) The behaviour is not really dependant on chipset (happens on several mobo's intel 965- P55) and OSes (XPsp3 and win7). Also the make of the USB keyboard doesn't seem to matter. I notice that sometimes when an USB kbd is plugged in, the system pauses for say 500-1000ms. (about 900-1000ms on disconnect, and 400-500 on the subsequent connect) It also happens for other USB devices (most notably mice and massstorage devices), but only the first time such device is connected to an installation. This disrupts the measurement and I really would like to get rid on this. I already tried to disable as much as possible. (powersave, teletubby mode (*) etc), and while this helped with the non-USB related disruptions of the measurement, it doesn't help with the USB related ones. (*) fyi, turning off themes (to resp. classic/non-aero), and turning off effects in system solved problems that occured when minimizing/maximizing the app. Any pointers to look into? I'm a bit stuck with this.

  • BizTalk - generating schema from Oracle stored proc with table variable argument

    - by Ron Savage
    I'm trying to set up a simple example project in BizTalk that gets changes made to a table in a SQL Server db and updates a copy of that table in an Oracle db. On the SQL Server side, I have a stored proc named GetItemChanges() that returns a variable number of records. On the Oracle side, I have a stored proc named Update_Item_Region_Table() designed to take a table of records as a parameter so that it can process all the records returned from GetItemChanges() in one call. It is defined like this: create or replace type itemrec is OBJECT ( UPC VARCHAR2(15), REGION VARCHAR2(5), LONG_DESCRIPTION VARCHAR2(50), POS_DESCRIPTION VARCHAR2(30), POS_DEPT VARCHAR2(5), ITEM_SIZE VARCHAR2(10), ITEM_UOM VARCHAR2(5), BRAND VARCHAR2(10), ITEM_STATUS VARCHAR2(5), TIME_STAMP VARCHAR2(20), COSTEDBYWEIGHT INTEGER ); create or replace type tbl_of_rec is table of itemrec; create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec ) IS errcode integer; errmsg varchar2(4000); BEGIN for recIndex in 1 .. Item_Data.COUNT loop update FL_ITEM_REGION_TEST set Region = Item_Data(recIndex).Region, Long_description = Item_Data(recIndex).Long_description, Pos_Description = Item_Data(recIndex).Pos_description, Pos_Dept = Item_Data(recIndex).Pos_dept, Item_Size = Item_Data(recIndex).Item_Size, Item_Uom = Item_Data(recIndex).Item_Uom, Brand = Item_Data(recIndex).Brand, Item_Status = Item_Data(recIndex).Item_Status, Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'), CostedByWeight = Item_Data(recIndex).CostedByWeight where UPC = Item_Data(recIndex).UPC; log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.'); end loop; EXCEPTION WHEN OTHERS THEN errcode := SQLCODE(); errmsg := SQLERRM(); log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...'); END; In my BizTalk project I generate the schemas and binding information for both stored procedures. For the Oracle procedure, I specified a path for the GeneratedUserTypesAssemblyFilePath parameter to generate a DLL to contain the definition of the data types. In the Send Port on the server, I put the path to that Types DLL in the UserAssembliesLoadPath parameter. I created a map to translate the GetItemChanges() schema to the Update_Item_Region_Table() schema. When I run it the data is extracted and transformed fine but causes an exception trying to pass the data to the Oracle proc: *The adapter failed to transmit message going to send port "WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom" with URL "oracledb://dvotst/". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: Custom type mapping for 'HOST_DATA.TBL_OF_REC' is not specified or is invalid.* So it is apparently not getting the information about the custom data type TBL_OF_REC into the Types DLL. Any tips on how to make this work?

  • Is there any way to customize the Windows 7 taskbar auto-hide behavior? Delay activation? Timer?

    - by calbar
    I'm becoming increasingly frustrated with the way Windows 7 handles showing a hidden taskbar. It's incredibly over-eager to pop out and obscure what I'm really trying to interact with, requiring me to move the mouse away, wait for it to auto-hide again, then resume what I was doing but more deliberately. After closely examining the behavior, it appears that a hidden taskbar "peeks out" from the edge by 2 or 3 pixels, and slowly moving your mouse into this area activates it; you don't even need to touch the edge of the screen. I would love it if there was a way to customize or change this behavior. Ideally, the taskbar would only pop out if you are actively "pushing" the edge of the screen it is hidden on. So activation only occurs once you've reached the screens edge and continue to move the mouse past a customizable threshold. Alternatively, a simple activation delay would suffice as well. So only if the mouse remains in that 2-3 pixel area (a.k.a. on the taskbar) for greater than a customizable amount of time does it pop out again. This would only be a fraction of a second. Often times the cursor simply "careens" off the edge of the screen while trying to focus on something nearby. Anyway, if there are any registry settings or utilities that can achieve either of these effects, that would be great! Thanks for your help.

  • How to process large block data visualization with Flex?

    - by hydra1983
    I know that's a big topic. However, it's better to know some general ideas to handle such problems. I have an application which requires Flex to render statistics data calculated instantly on the client side from a downloaded data set. The problems are: the data set is large and needs more than 10 seconds to be downloaded. there are some filters to control the statistics calculation algorithms. If user changes the filters, it would take a long time to recalculate the result and freeze the UI.

  • AJAX XML reply node value iteration

    - by XpiritO
    Hi there, guys. I would really appreciate to get your help on this, as I can't seem to detect and solve the problem I'm having with an AJAX functionality on a site that I'm currently developing. I have a webform that makes an asynchronous call to a handler (.ashx) that delivers a XML response that is later processed by a Javascript client-side function that places it's contents into the user-interface. I'm attaching an example of the response generated by my handler, and what I would like to know is how can I get all the <body> element innerHTML (with the text and child nodes) contents to append it to a <span> element on the user-interface. Can anyone help me out with this? XML Response returned by the handler (checked via Firebug): <message> <content> <messageId>2</messageId> <from>Barack Obama</from> <fromMail>[email protected]</fromMail> <subject>Yes, we can... get World Peace</subject> <body>Hello, dear citizen. I'm sending you this message to invite you to join us! <a href="http://www.whitehouse.gov">Test link</a> Thank you for your time.</body> </content> </message> Client-side Javascript function to affect the user-interface innerHTML property with the data returned via AJAX: function GetMessageContentsCallback(args, resp) { //XML Parser try { //Internet Explorer xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async = "false"; xmlDoc.loadXML(resp); } catch (e) { parser = new DOMParser(); xmlDoc = parser.parseFromString(resp, "text/xml"); } var msgReply = xmlDoc.getElementsByTagName('message')[0]; var ajaxRespondeBodyInnerHTML = msgReply.getElementsByTagName(body)[0].firstChild.nodeValue; //this currently only delivers inner text content, without the <a href... bit and subsequent text document.getElementById("bodySpan").innerHTML = ajaxRespondeBodyInnerHTML; }

  • tapestry5 page to render plain text

    - by pstanton
    Hi All, I've been looking but can't find the the documentation: Is there a way to have a page render a response without the wrapping HTML elements and just print whatever is provided in the body of the tml or alternatively whatever is set in MarkupWriter.write during @BeginRender? I need a page that does some server side processing and returns pure javascript for an external application to request. If that is impossible, is it possible to expose the tapestry Ioc to a servlet in the same app? Thanks, p.

  • have PDF form, need to port to website

    - by Alex
    So here is what I have: a PDF form (job application) that a client is requesting to put on their website as a form and the data gets sent to them when an applicant on the site fills the form out. My idea is as follows: dissecting the PDF, taking its fields and making the HTML form, then processing on the server side, creating the new PDF and emailing as an attachment to the client. However, something tells me that there is a better, more effective way of doing it. Is that so?

    I have a custom list, with calculation, in SharePoint. Everything worked fine until recently when the DataSheet will show strange or wrong % calculation in a % column. But the Standard View will show correct values. IT checked the server side and everything looked ok, I checked the formulas and even re-did them in the column and the issue persist. Anyone, any suggestion? Thanks,

  • How can I create and use a web service in public but still restrict its use to only my app?

    - by Glenn
    I'm creating a web service with create/update/delete calls. But for now I'd like to restrict use of it on my own web app and no other clients. How can I have clear text javascript code that makes these calls but still be confident the credentials won't be used elsewhere? My idea is to use server side generated nonces for each request. But I am open to different ideas you guys may have. Thanks.
