  • bind event handler on keydown listen function JavaScript jQuery

    - by user1644123
    I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element. My syntax may be the wrong approach, but it works for the 1st condition, but not the 2nd. I think I have the conditional statement in the wrong place. How can I rewrite this to work as intended? Thank you kindly, in advance! $(document).keydown(function(e) { switch (e.which) { case 37: break; case 38: break; case 39: break; case 40: //bottom arrow key var hits = 0; if (hits % 2 !== 0) { $('#wrap').animate({ scrollTop: $("#scrollToHere").offset().top }, 2800); } else { $('#wrap').animate({ scrollTop: $("#scroll2ToHere").offset().top }, 2800); } hits++; return false; break; } })? *I moved "var hits = 0;" to the top, but it only works! But is there a way I can reset the whole thing after every two hits? I want to reset because when there is a bug and if I press a 3rd time it scrolls to the very top of the page, where there is no element to make it scroll to the top. Why would it scroll to the top of the page if I never scripted it to do so?? *

  • Deleting MySQL rows causes lock table error

    - by Dave L
    I had a couple million rows to delete but they can't be deleted at once without this error ERROR 1206 (HY000): The total number of locks exceeds the lock table size So I wrote a script to delete 100,000 rows 10,000 at a time. It ran once but when I run it a second time I get the error on the first attempt to delete 10,000. The way I'm trying to delete the 10,000 rows is to use a delete statement that refers to all 2 million rows but I use a limit clause to affect only 10,000. I've tried adding an "unlock tables;" statement to the script before the first delete but that doesn't help. I still get the lock table error on the first delete. Any ideas how I can do this? Is there a way I can tell it NOT to lock records? I can make sure nothing else is accessing the table.

  • Formvalidator from the iframe.

    - by basit74
    Hello I have a following formvalidatior function in my document. function formValidator(formid) { var form = cic.$(formid); if(!form) return (''); var errors = []; var len = form.elements.length; for(var elementIdx = 0; elementIdx < len; elementIdx++) { var element = form.elements[elementIdx]; if(!element && !element.getAttribute('validationtype')) return (''); switch (element.getAttribute('validationtype')) { case 'text' : if(cic.getValue(element).strip() == "") errors.push(element.getAttribute('validationmsg')); break; case 'email' : if(!cic.isEmail(cic.getValue(element))) errors.push(element.getAttribute('validationmsg')); break; case 'numeric' : if(isNaN(cic.getValue(element).replace(',', '.'))) errors.push(element.getAttribute('validationmsg')); break; case 'confirm' : if(cic.getValue(cic.$(element.getAttribute('sourcefield'))) !== cic.getValue(element)) errors.push(element.getAttribute('validationmsg')); break; } } return (errors.length > 0) ? '<li>' + errors.uniq().join("<li>") : ''; } It works fine, now I have an Iframe in my document, and that I frame contains the form to validate. What will be the best practice to change this function in such a way that it can validate document forms and iframe from simeltaniously. Thanks

  • Join two tables with same # of row but sorted for NULL

    - by VISQL
    I need to join two tables with the same number of rows. Each table has 1 column. There is NO CONNECTING COLUMN to reference for a join. I need to join them side by side because each table was sorted separately so that numeric values are at the top in descinding order. The Table Earners has income values from say 200K down to 0. I cannot just select using 2 cases, because then I will have my first row with Incomes above 100K, but the first 20 or so entries in the second row are NULL. I want the second row to also be sorted descending. I looked up using ORDER BY within CASE but there is no such thing. I have tried to read about row_number() but none of the examples seem to match or make sense. drop table #20plus select case when Income >= 20000 AND Income < 100000 then Income end as 'mula' into #20plus from Earners order by mula desc drop table #100plus select case when Income >= 100000 then Income end as 'dinero' into #100plus from Earners order by dinero desc Select A.dinero, B.mula FROM #100plus as A JOIN #20plus as B ON A.????? = B.????? Since both A and B are sorted descending, moving all NULL to the bottom, what can I reference to join the two tables? Previous output using one SELECT statement with 2 CASE statements dinero mula 2.12688e+007 NULL 1.80031e+007 NULL 1.92415e+006 NULL … … NULL 93530.7 NULL 91000 NULL 84500 Desired output using one SELECT statement after creating two temp TABLES dinero mula 2.12688e+007 93530.7 1.80031e+007 91000 1.92415e+006 84500 … 82500 NULL 82000 NULL … NULL NULL This is Microsoft SQL Server 2008. I'm super new to this, so please give an answer as clear and simplified as possible. Thank you.

  • How can the Three-Phase Commit Protocol (3PC) guarantee atomicity?

    - by AndiDog
    I'm currently exploring worst case scenarios of atomic commit protocols like 2PC and 3PC and am stuck at the point that I can't find out why 3PC can guarantee atomicity. That is, how does it guarantee that if cohort A commits, cohort B also commits? Here's the simplified 3PC from the Wikipedia article: Now let's assume the following case: Two cohorts participate in the transaction (A and B) Both do their work, then vote for commit Coordinator now sends precommit messages... A receives the precommit message, acknowledges, and then goes offline for a long time B doesn't receive the precommit message (whatever the reason might be) and is thus still in "uncertain" state The results: Coordinator aborts the transaction because not all precommit messages were sent and acknowledged successfully A, who is in precommit state, is still offline, thus times out and commits B aborts in any case: He either stays offline and times out (causes abort) or comes online and receives the abort command from the coordinator And there you have it: One cohort committed, another aborted. The transaction is screwed. So what am I missing here? In my understanding, if the automatic commit on timeout (in precommit state) was replaced by infinitely waiting for a coordinator command, that case should work fine.

  • Show NSSegmentedControl menu when segment clicked, despite having set action

    - by Justin Williams
    I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked: - (IBAction)performActionFromClick:(id)sender { NSInteger selectedSegment = [sender selectedSegment]; NSInteger clickedSegmentTag = [[sender cell] tagForSegment:selectedSegment]; switch (clickedSegmentTag) { case 0: [self showNewEventWindow:nil]; break; case 1: [self showNewTaskWindow:nil]; break; case 2: [self toggleTaskSplitView:nil]; break; case 3: [self showGearMenu]; break; } } Segment 4 has has a menu attached to it in the awakeFromNib method. I'd like this menu to drop down when the user clicks the segment. At this point, it only will drop if the user clicks & holds down on the menu. From my research online this is because of the connected action. I'm presently working around it by using some code to get the origin point of the segment control and popping up the context menu using NSMenu's popUpContextMenu:withEvent:forView but this is pretty hacktastic and looks bad compared to the standard behavior of having the menu drop down below the segmented control cell. Is there a way I can have the menu drop down as it should after a single click rather than doing the hacky context menu thing?

  • Counting problem C#

    - by MadBoy
    Hello, I've a bit of a problem. I'm adding numbers to ArrayList like 156, 340 (when it is TransferIn or Buy) etc and then i remove them doing it like 156, 340 (when it's TransferOut, Sell). Following solution works for that without a problem. The problem I have is that for some old data employees were entering sum's like 1500 instead of 500+400+100+500. How would I change it so that when there's Sell/TransferOut and there's no match inside ArrayList it should try to add multiple items from that ArrayList and find elements that combine into aggregate. ArrayList alNew = new ArrayList(); ArrayList alNewPoIle = new ArrayList(); ArrayList alNewCo = new ArrayList(); string tempAkcjeCzynnosc = (string) alInstrumentCzynnoscBezNumerow[i]; string tempAkcjeInId = (string) alInstrumentNazwaBezNumerow[i]; decimal varAkcjeCena = (decimal) alInstrumentCenaBezNumerow[i]; decimal varAkcjeIlosc = (decimal) alInstrumentIloscBezNumerow[i]; int index; switch (tempAkcjeCzynnosc) { case "Sell": case "TransferOut": index = alNew.IndexOf(varAkcjeIlosc); if (index != -1) { alNew.RemoveAt(index); alNewPoIle.RemoveAt(index); alNewCo.RemoveAt(index); } else { // Number without match encountred } break; case "Buy": case "TransferIn": alNew.Add(varAkcjeIlosc); alNewPoIle.Add(varAkcjeCena); alNewCo.Add(tempAkcjeInId); break; } }

  • Is there a practical benefit to casting a NULL pointer to an object and calling one of its member fu

    - by zdawg
    Ok, so I know that technically this is undefined behavior, but nonetheless, I've seen this more than once in production code. And please correct me if I'm wrong, but I've also heard that some people use this "feature" as a somewhat legitimate substitute of a lacking aspect of the current C++ standard, namely, the inability to obtain the address (well, offset really) of a member function. For example, this is out of a popular implementation of a PCRE (Perl-compatible Regular Expression) library: #ifndef offsetof #define offsetof(p_type,field) ((size_t)&(((p_type *)0)->field)) #endif One can debate whether the exploitation of such a language subtlety in a case like this is valid or not, or even necessary, but I've also seen it used like this: struct Result { void stat() { if(this) // do something... else // do something else... } }; // ...somewhere else in the code... ((Result*)0)->stat(); This works just fine! It avoids a null pointer dereference by testing for the existence of this, and it does not try to access class members in the else block. So long as these guards are in place, it's legitimate code, right? So the question remains: Is there a practical use case, where one would benefit from using such a construct? I'm especially concerned about the second case, since the first case is more of a workaround for a language limitation. Or is it? PS. Sorry about the C-style casts, unfortunately people still prefer to type less if they can.

  • SQL Server 2008 - Error starting service - model.mdf not found?!

    - by alex
    my SQL server 2008 was running fine. About an hour ago, it suddenly stopped - the MSSQLSERVER service had stopped I right clicked, clicked start, and it said the service had started, and stopped I looked in the event log and saw these two errors: 17207 : udopen: Operating system error 3(error not found) during the creation/opening of physical device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf. 17204 : FCB::Open failed: Could not open device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf for virtual device number (VDN) 1. The model.mdf db has NEVER been in that location - i specified drive F: to use for data / log during install. I checked the SQL Configuration Manager, to try and set startup params, but SQL Server is not listed as one of the services..... EDIT: I've now moved the db to where it was looking for: C:\Program Files\Microsoft SQL Server\MSSQL\data\ directory. Now if I start the service, it still does not work - i get this error message in the log: Could not find row in sysindexes for database ID 3, object ID 1, index ID 1.

  • Problem with UITextView

    - by user367039
    I have a strange problem with trying to pass a string from one viewcontroller to another view controller if the string originates from a UITextview instead of UITextfield. Both UITextview.text and UITextfield.text are of type NSString. The following code takes either Textfield.text or Textview.text depending on the fieldType and puts it into a string called aString. NSString *aString = [[NSString alloc] init]; if (fieldType == 3) { aString = textView.text; } else { aString = textField.text; } When I examine aString on either cases, I can see that it has successfully assigned the text into aString. I then pass the string to the other view controller using this code. [delegate updateSite:aString :editedFieldKey :fieldType]; [self.navigationController popViewControllerAnimated:YES]; This works fine if aString originated from textfield.text but nothing happens except the view controller is popped if aString was from textview.text This is the code that takes aString and does stuff with it, however it doesn't even execute the first line of code "NSLog(@"Returned object: %@, field type:%@", aString,editedFieldKey);" if aString was from textview.text Any help will be appreciated. -(void)updateSite:(NSString *)aString :(NSString *)editedFieldKey :(int)fieldType { NSLog(@"Returned object: %@, field type:%@", aString,editedFieldKey); switch (fieldType) { case 0: //string [aDiveSite setValue:aString forKey:editedFieldKey] ; NSLog(@"String set %@",[aDiveSite valueForKey:editedFieldKey] ); break; case 1: //int [aDiveSite setValue:[NSNumber numberWithInt:aString.intValue] forKey:editedFieldKey]; NSLog(@"Integer set"); break; case 2: //float NSLog(@"Saving floating value"); [aDiveSite setValue:[NSNumber numberWithFloat:aString.floatValue] forKey:editedFieldKey]; NSLog(@"Float set"); break; case 3: //Text view [aDiveSite setValue:aString forKey:editedFieldKey]; NSLog(@"Textview text saved"); default: break; } [self.tableView reloadData]; }

  • REST API - why use PUT DELETE POST GET?

    - by Andre
    So -i was looking through some articles on creating REST API's. And some of them suggest using all types of HTTP requests: like PUT DELETE POST GET. So - we would create for example index.php and write API this way: $method = $_SERVER['REQUEST_METHOD']; $request = split("/", substr(@$_SERVER['PATH_INFO'], 1)); switch ($method) { case 'PUT': ....some put action.... break; case 'POST': ....some post action.... break; case 'GET': ....some get action.... break; case 'DELETE': ....some delete action.... break; } Ok - granted - I don't know much baout web services (yet). But - wouldn't it be easier to just accept JSON object through normal $_POST and then respond in JSON as well. We can easily serialize/deserialize via php's json_encode and json_decode and do whatever we want with that data without having to deal with different HTTP request methods... Am I missing something? UPDATE 1: Ok - after digging through various API's and learning a lot about XML-RPC, JSON-RPC, SOAP, REST I came to a conclusion that this type of API is sound. Actually stack exchange is pretty much using this approach on their sites and I do think that these people know what they are doing Stack Exchange API.

  • What is the IoC / "Springy" way to handle MVP in GWT? (Hint, probably not the Spring Roo 1.1 way)

    - by Ehrann Mehdan
    This is the Spring Roo 1.1 way of doing a factory that returns a GWT Activity (Yes, Spring Framework) public Activity getActivity(ProxyPlace place) { switch (place.getOperation()) { case DETAILS: return new EmployeeDetailsActivity((EntityProxyId<EmployeeProxy>)place.getProxyId(), requests, placeController, ScaffoldApp.isMobile() ? EmployeeMobileDetailsView.instance() : EmployeeDetailsView.instance()); case EDIT: return makeEditActivity(place); case CREATE: return makeCreateActivity(); } throw new IllegalArgumentException("Unknown operation " + place.getOperation()); } It seems to me that we just went back hundred of years if we use a switch case with constants to make a factory. Now this is official auto generated Spring roo 1.1 with GWT / GAE integration, I kid you not I can only assume this is some executives empty announcements because this is definitly not Spring It seems VMWare and Google were too fast to get something out and didn't quite finish it, isn't it? Am I missing something or this is half baked and by far not the way Spring + GWT MVP should work? Do you have a better example of how Spring, GWT (2.1 MVP approach) and GAE should connect? I would hate to do all the plumbing of managing history and activities like this. (no annotations? IOC?) I also would hate to reinvent the wheel and write my own Spring enhancement just to find someone else did the same, or worse, find out that SpringSource and Google will release roo 1.2 soon and make it right

  • Finding part of a string that a user has sent via POST

    - by blerh
    My users can send links from popular file hosts like Rapidshare, Megaupload, Hotfile and FileFactory. I need to somehow find out what filehost they sent the link from and use the correct class for it appropriately. For example, if I sent a Rapidshare link in a form on my web page, I need to somehow cycle through each file host that I allow until I find the text rapidshare.com, then I know the user has posted a Rapidshare link. Perhaps a PHP example: switch($_POST['link']) { case strstr($_POST['link'], 'rapidshare.com'): // the link is a Rapidshare one break; case strstr($_POST['link'], 'megaupload.com'): // the link is a Megaupload one break; case strstr($_POST['link'], 'hotfile.com'): // the link is a Hotfile one break; case strstr($_POST['link'], 'filefactory.com'): // the link is a Filefactory one break; } However, I know for a fact this isn't correct and I'd rather not use a huge IF statement if I can help it. Does anyone have any solution to this problem? If you need me to explain more I can try, English isn't my native language so it's kinda hard. Thanks all.

  • about option buttons in User form

    - by Mars
    I have a question: I need to create a user form that contain that usual OK and Cancel Buttons. It also should contain two sets of Options buttons, each set placed inside a frame. The captions on the first set should be basketball, baseball, football, the captions on the second set should be watch on TV and Go to games. I need to write the event handlers and code in a module so that when the program runs, the user sees the form. If the user makes a couple of choices and clicks OK, he should see a message like "Your favorite sport is basketball, and you usually watch on TV." If the user clicks Cancel, the message "Sorry you don't want to play" should appear. I think I almost have it working, but I don't know why I cannot successfully execute the Macro. My Code is : Option Explicit Private Sub CommandButton2_Click() MsgBox ("sorry if you don't want to play") End Sub Private Sub commandbuttons_Click() Dim optbasket As String, optbaseball As String, optfootball As String Dim optwog As String, optgtg As String Select Case True Case optbasket optbasket = True Case optbaseball optbaseball = True Case optfootball optfootball = True End Select If optwog Then optwog = True Else optgtg = True End If btnok = MsgBox("you favorite sport is " & Frame1.Value & "you usually " & Frame2.Value & ",") End Sub Private Sub OptionButton1_Click() End Sub Private Sub btmcancel_Click() End Sub Private Sub btnok_Click() End Sub Private Sub Frame1_Click() End Sub Private Sub Frame2_Click() End Sub Private Sub optbaseball_Click() End Sub Private Sub optbasketball_Click() End Sub Private Sub optfootball_Click() End Sub Thank you very much!!!

  • looping .mpeg dump

    - by Matt Cook
    Need to dump an MPEG2 file in a loop, either to stdout or a named pipe. This works: $ { while : ; do cat myLoop.mpg; done; } | vlc - This works on a text file containing "1234\n": $ mkfifo myPipe $ cat test.txt > myPipe & < myPipe tee -a myPipe | cat - (it correctly loops, outputting "1234" on every line). Why does the following NOT work? $ cat myLoop.mpg > myPipe & < myPipe tee -a myPipe | vlc myPipe I'm primarily interested in re-writing the first statement to remove the improper "cat myLoop.mpg" statement. Will be inputting into VLC, or into FFMPEG and then piped into VLC.

  • The new SSIS in SQL2005/SQL2008 are oversized

    I studied the new MERGE Statement and there is a nice example for importing a flatfile. INSERT <Table> SELECT * FROM OPENROWSET BULK <Import-Flat-File>, <Format-File>... seems to be a good replacment for such a simple job and avoids to build a SSIS-Package. EXEC XP_CMDSHELL bcp <Table or View> out <Flat-File> ... is almost simpler than building an SSIS, isn't it? (I know that the MERGE-Statement doesn't run on a SQL2005)

  • Using child visitor in C#

    - by Thomas Matthews
    I am setting up a testing component and trying to keep it generic. I want to use a generic Visitor class, but not sure about using descendant classes.

  • Is there a definitive reference document for Ruby syntax?

    - by JSW
    I'm searching for a definitive document on Ruby syntax. I know about the definitive documents for the core API and standard library, but what about the syntax itself? For instance, such a document should cover: reserved words, string literals syntax, naming rules for variables/classes/modules, all the conditional statements and their permutations, and so forth. I know there are many books and tutorials, yes, but every one of them is essentially a tutorial, each one having a range of different depth and focus. They will all, by necessity of brevity and narrative flow, omit certain details of the language that the author deems insignificant. For instance, did you know that you can use a case statement without an initial case value, and it will then execute the first true when clause? Any given Ruby book or tutorial may or may not cover that particular lesser-known functionality of the case syntax. It's not discussed in the section in "Programming Ruby" about case statements. But that is just one small example. So far the best documentation I've found is the rubyspec project, which appears to be an attempt to write a complete test suite for the language. That's not bad, but it's a bit hard to use from a practical standpoint as a developer working on my own projects. Am I just missing something or is there really no definitive readable document defining the whole of Ruby syntax?

  • PHP Function parameters - problem with var not being set

    - by Marty
    So I am obviously not a very good programmer. I have written this small function: function dispAdjuggler($atts) { extract(shortcode_atts(array( 'slot' => '' ), $atts)); $adspot = ''; $adtype = ''; // Get blog # we're on global $blog_id; switch ($blog_id) { case 1: // root blog HOME page if (is_home()) { switch ($slot) { case 'top_leaderboard': $adspot = '855525'; $adtype = '608934'; break; case 'right_halfpage': $adspot = '855216'; $adtype = '855220'; break; case 'right_med-rectangle': $adspot = '858222'; $adtype = '613526'; break; default: throw new Exception("Ad slot is not defined"); break; } When I reference the function on a page like so: <?php dispAdjuggler("top_leaderboard"); ?> The switch is throwing the default exception. What am I doing wrong here? Thanks!!
