  • two HashMap iteration

    - by user431276
    I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

  • Decorator Pattern - Multiple wrappers or quantity property?

    - by Jiminizer
    I'm making use of the decorator pattern for one of the first times, as part of a Uni project. As far as I can see, the pattern seems to be meant more for adding functionality in a modular manner, however we've been taught it with uses such as a coffee or pizza maker, where the object has modular components that are added - changing properties rather than behaviour. I'm trying to make the most of both uses, however I've come up with a question. In the example in the book we're using (Head First Design Patterns), the pattern is used in a coffee shop creating different coffees. So, for example, milk, froth, sugar, sprinkles are all decorators. How would you implement a system that used the same decorator multiple times (for example, a coffee with two sugars)? Would you rewrap the coffee, or give sugar a quantity property? Or (as i'm starting to suspect) would this never be an issue as the pattern isn't designed to be used this way?

  • mysql LAST_INSERT_ID() used with multiple records INSERT statement

    - by bogdan
    Hello, If i insert multiple records with a loop that executes a single record insert, the last insert id returned is, as expected, the last one... but if i do a multiple records insert statement: INSERT INTO people (name,age) VALUES('William',25),('Bart',15),('Mary',12); let's say the three above are the first records inserted in the table...after the insert statement i expected last insert id to return 3, but it returned 1...the first insert id for the statement in question... So can someone please confirm if this is the normal behavior of LAST_INSERT_ID() in the context of multiple records INSERT statements...so i can base my code on it thanks :)

    - by Mike
    I have a file containing the data shown below. The first comma-delimited field may be repeated any number of times, and I want to print only the lines after the sixth repetition of any value of this field For example, there are eight fields with 1111111 as the first field, and I want to print only the seventh and eighth of these records Input file: 1111111,aaaaaaaa,14 1111111,bbbbbbbb,14 1111111,cccccccc,14 1111111,dddddddd,14 1111111,eeeeeeee,14 1111111,ffffffff,14 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,aaaaaaaa,14 2222222,bbbbbbbb,14 2222222,cccccccc,14 2222222,dddddddd,14 2222222,eeeeeeee,14 2222222,ffffffff,14 2222222,gggggggg,14 3333333,aaaaaaaa,14 3333333,bbbbbbbb,14 3333333,cccccccc,14 3333333,dddddddd,14 3333333,eeeeeeee,14 3333333,ffffffff,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 Output: 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,gggggggg,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 What I have tried is to transponse the 2nd and 3rd fields with respect to 1st, so that I can use nawk on the field of $7 or $8 #!/usr/bin/ksh awk -F"," '{ a[$1]; b[$1]=b[$1]","$2 c[$1]=c[$1]","$3} END{ for(i in a){ print i","b[i]","c[i]} } ' file > output.txt

  • C++: Most common way to talk to one application from the other one

    - by MInner
    In bare outlines, I've got an application which looks through the directories at startup and creates special files' index - after that it works like daemon. The other application creates such 'special' files and places them in some directory. What way of informing the first application about a new file (to index it) is the most common, simple (the first one is run-time, so it shouldn't slow it too much), and cross-platform if it is possible? I've looked through RPC and IPC but they are too heavy (also non-cross-platform and slow (need a lot of features to work - I need a simple light well-working way), probably).

  • unknown column in where clause

    - by ranzy
    $result = mysql_query("SELECT * FROM Volunteers WHERE Volunteers.eventID = " . $var); $sql = mysql_query("SELECT * FROM Members WHERE Members.pid = " . $temp); I am also doing or die(mysql_error()) at the end of both statements if that matter. My problem is that the first statement executes perfectly but in that table I store an attribute called pid. So the second statement is supposed to take that and return the row where it equals that pid so I can get the name. I get an error that says unknown column in 'a2' in 'where clause' where a2 the pid attribute returned from the first statement. Thanks for any help!

  • MonoRail - Clearing value on edit form submission doesn't trigger validation

    - by Justin
    Hey, In a MonoRail app I have an add/edit view. On add if I don't pick a value for a dropdown I get a validation error and am forced to pick a value. However, if I then edit that same item and reset the dropdown back to the first item ("Select an Item", "0"), it saves and doesn't say it was invalid. Debugging the entity sent back to the server, I can see that it's sending the original value for the dropdown instead of the new value of "0". What's going on here? The first thing I would expect is that it would trigger the validation since the dropdown value isn't set. The second thing I would expect is that it would send the new value I send, not the original. It does send the new value if I change it to another value, but it's as if it has internal logic that says - "I'm updating this entity and a new value was not passed, just don't change the entity value." Thanks, Justin

  • Chain dynamically created dropdowns with JQuery

    - by ricardocasares
    I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

  • Using CreateFileMapping between to programs - C

    - by Jamie Keeling
    Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

  • UIView Horizontal scroll for a part of a screen

    - by Futur
    Hi Friends, I have a requirement for scrolling a part of a view horizontally. there are 2 views, mainView(0,70,320*2,400) and a horizontalView(0,0,320*2,160)[this horizontalView has an internal UIScrollView with the same frame] So the horizontal view will occupy the first section of the screen and it should only be scrollable horizontally (and the other part of the mainView - the other part of the screen should be static). how to achieve this? i am getting a general scroll for the whole page not for the first section alone. am i in the right direction for this problem? please advice Thank you

  • Can you control pinterest's "find image" results?

    - by anthony
    Rather than add Pin It buttons through our site, I would like to simply control what images show up in Pinterest's "Find Image" results if a user decides to pin one of our URLs. As of now, "Find Images" allows the user to scroll through the images it finds on the page so they can select which image to pin. The "found" images start with the first jpg in the html file, I'm assuming (could that be a bad assumption??). On our site, this forces a user to scroll through about 15 navigation and promotion images before arriving at the featured product image. Is there any way to specify this image to show first in those results? Maybe through a meta tag, or by adding a class or id to the element? Without a public Pinterest API, this seems like just guesswork, but I wanted to see if anyone else has run into this, or solved this. Thanks.

  • Handling changes in column order when importing CSV files

    - by Scott
    I have a CSV file. The first row will always contain column headers. Depending on a variety of factors, the order of columns may change and, in rare circumstances, some columns may not be present. These changes are beyond my control. My thoughts, so far, on how to address this. I'll read the first row of the file and use the values to generate a list of columns contained in the source file. The destination file will use the same column names as the source. This should be as simple as searching for identical names in the source and destination, then just mapping the column index values, right? What are your recommendations for handling this?

  • Incrmenting a Cookies with PHP (Beginner Question)

    - by BandonRandon
    Hello, I have used sessions before but never cookies. I would like to use cookies for two reasons: 1) it's something new to learn 2) I would like to have the cookie expire in an hour or so (i know in the code example it expires in 40 sec) I am trying to write a basic if statement that if($counter=="1") { //do this second } elseif ($counter >="2") { //do this every time after the first and second } else {// this is the first action as counter is zero } Here is the code I'm using to set the cookie: // if cookie doesnt exsist, set the default if(!isset($_COOKIE["counter_cookie"])) { $counter = setcookie("counter_cookie", 0 ,time()+40); } // increment it $counter++; // save it setcookie("counter_cookie", $counter,time()+40); $counter = $_COOKIE["counter_cookie"]; The problem is that the counter will be set from 0 to 1 but won't be set from 1 to 2 and so on. Any help would be great I know this is a really simple stupid question :| Thanks!

  • Jquery-UI tabs : Double loading of the default tab with

    - by Stephane
    I use jqueryui-tabs to display a tabbed UI. here is how my markup looks in a MasterPage: <div id="channel-tabs" class="ui-tabs"> <ul class="ui-tabs-nav"> <li><%=Html.ActionLink("Blogs", "Index", "Blog", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, new{ title="Blog Results" }) %></li> <li><%=Html.ActionLink("Forums", "Index", "Forums", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> <li><%=Html.ActionLink("Twitter", "Index", "Twitter", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> </ul> <div id="Blog_Results"> <asp:ContentPlaceHolder ID="ResultPlaceHolder" runat="server"> </asp:ContentPlaceHolder> </div> If the content is loaded via ajax, I return a partial view with the content of the tab. If the content is loaded directly, I load a page that include the content in the ContentPlaceHolder. somewhat like this : <asp:Content ID="Content2" ContentPlaceHolderID="BlogPlaceHolder" runat="server"> <%=Html.Partial("Partial",Model) %> </asp:Content> //same goes for the other tabs. With this in place, if I access the url "/Forums" It loads the forum content in the Blog tab first, trigger the ajax load of the Blog tab and replace the content with the blog content. I tried putting a different placeholder for each tab, but that didn't fix everything either, since when loading "/Forums" it will sure load the forum tab, but the Blog tab will show up first. Furthermore, when using separate placeholders, If I load the "/Blogs" url, It will first load the content statically in the Blog contentplaceholder and then trigger an ajax call to load it a second time and replace it. If I just link the tab to the hashtag, then when loading the forum tabs, I won't get the blog content... How would you achieve the expected behaviour? I feel like I might have a deeper probelm in the organization of my views. Is putting the tabs in the masterpage the way to go? Maybe I should just hijax the links manually and not rely on jquery-ui tabs to do the work for me. I cannot load all tabs by default and display them using the hash tags, I need an ajax loading because it is a search process that can be long. So to sum up : /Forum should load the forum tab, and let the other tabs be loaded with an ajax call when clicking on it. /Twitter should load the twitter tab and let the other tabs.... the same goes for /Blogs and any tabs I would add later.

  • cflock do not throw timeout for same url called in same browser

    - by Pritesh Patel
    I am trying lock block on page test.cfm and below is code written on page. <cfscript> writeOutput("Before lock at #now()#"); lock name="threadlock" timeout="3" type="exclusive" { writeOutput("<br/>started at #now()#"); thread action="sleep" duration="10000"; writeOutput("<br/>ended at #now()#"); } writeOutput("<br/>After lock at #now()#"); </cfscript> assuming my url for page is http://localhost.local/test.cfm and running it on browser in two different tabs. I was expecting one of the url will throw timeout error after 3 second since another url lock it atleast for 10 seconds due to thread sleep. Surprisingly I do not get any timeout error rather second page call run after 10 seconds as first call finish execution. But I am appending some url parameter (e.g. http://localhost.local/test.cfm?q=1) will throw error. Also I am calling same url in different browser then one of the call will throw timeout issue. Is lock based on session and url? Update Here is output for two different cases: Case 1: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:35'} started at {ts '2013-10-18 09:21:35'} ended at {ts '2013-10-18 09:21:45'} After lock at {ts '2013-10-18 09:21:45'} TAB2 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:45'} started at {ts '2013-10-18 09:21:45'} ended at {ts '2013-10-18 09:21:55'} After lock at {ts '2013-10-18 09:21:55'} Case 2: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:27:18'} started at {ts '2013-10-18 09:27:18'} ended at {ts '2013-10-18 09:27:28'} After lock at {ts '2013-10-18 09:27:28'} TAB2 Url: http://localhost.local/test/test.cfm? (Added ? at the end) Before lock at {ts '2013-10-18 09:27:20'} A timeout occurred while attempting to lock threadlock. The error occurred in C:/inetpub/wwwroot/test/test.cfm: line 13 11 : 12 : <cfoutput>Before lock at #now()#</cfoutput> 13 : <cflock name="threadlock" timeout="3" type="exclusive"> 14 : <cfoutput><br/>started at #now()#</cfoutput> 15 : <cfthread action="sleep" duration="10000"/> ... Result for case 2 as expected. For case 1, strange thing I just noticed is tab 2 output "Before lock at {ts '2013-10-18 09:21:45'} indicates that whole request start after 10 seconds (means after the complete execution of first tab) when I have fired it in second URL just after 2 seconds of first tabs.

  • SQLite SQLite column can't be updated to any value but zero (real type)

  • generate an array from an array with conditions

    - by Aman
    Suppose i have an array $x = (31,12,13,25,18,10); I want to reduce this array in such a way that the value of each array element is 32. so after work my array will become $newx = (32,32,32,13); I have to generate this array in such a way the sum of array values is never greater than 32. so to create first value, i will reduce 1 from second index value i.e. 12, so the second value will become 11 and first index value will become 31+1 =32. This process should continue so that each array value becomes equal to 32.

  • Java/Swing: Problem with key listener

    - by Mike
    I have a search dialog with a JTextField that's being used as a search box. When the user types something, it searches the DB, shows the result in a JTable and selects the first item in it. If the first result is what they were looking for, I want to let them quickly accept the dialog, by pressing Enter (while the JTextField is focused). So I added a KeyListener to the JTextField and it's working OK. Now the problem: The user opens can open the dialog by pressing Enter when a "Search" button on the dialog's parent frame is focused. The dialog is displayed and the JTextField gets the keyReleased event (from the Enter key that displayed it), so it shows up and closes. If the user holds Enter down, then the JTextField receives the keyPressed, keyTyped and keyReleased events. How can I fix without resorting to ugly workarounds? Platform is Windows 7 x64, btw. Test NetBeans project here: http://dl.dropbox.com/u/6354360/KeyListenerTest.zip Thanks.

  • In SQL / MySQL, what is the difference between "On" and "Where" in a join statement?

    - by Jian Lin
    The following statements give the same result (one is using "on", and the other using "where"): mysql> select * from gifts INNER JOIN sentGifts on gifts.giftID = sentGifts.giftID; mysql> select * from gifts INNER JOIN sentGifts where gifts.giftID = sentGifts.giftID; I can only see in a case of a Left Outer Join finding the "unmatched" cases: (to find out the gifts that were never sent by anybody) mysql> select name from gifts LEFT OUTER JOIN sentgifts on gifts.giftID = sentgifts.giftID where sentgifts.giftID IS NULL; In this case, it is first using "on", and then "where". Does the "on" first do the matching, and then "where" does the "secondary" filtering? Or is there a more general rule of using "on" versus "where"? Thanks.

  • In a graph, how to find the nearest node to a group of nodes?

    - by Nikola
    Hello, I have an undirected, unweighted graph, which doesn't have to be planar. I also have a subset of graph's nodes (true subset) and I need to find a node not belonging to the subset, with minimum sum of distances to all nodes in the subset. So far, I have implemented breath-first search starting from each node in the subset, and the intersection that occurs first is the node I am looking for. Unfortunately, it is running too slow since the graph contains a large number of nodes. Any advice or comment will be appreciated. Thank you, Nikola

I thought this error was due to a problem with memory allocation. Can someone shed some light on this.

  • Is it possible to invoke NSDictionary's valueForKeyPath: when a key contains periods?

    - by Jonukas
    I'm trying to get the value of the repeatInterval key in the com.apple.scheduler plist. I'd like to just use NSDictionary's valueForKeyPath: method like so: CFPropertyListRef value; value = CFPreferencesCopyValue(CFSTR("AbsoluteSchedule"), CFSTR("com.apple.scheduler"), kCFPreferencesCurrentUser, kCFPreferencesCurrentHost); NSNumber *repeatInterval = [(NSDictionary *)value valueForKeyPath:@"com.apple.SoftwareUpdate.SUCheckSchedulerTag.Timer.repeatInterval"]; But the problem with this is that the first key is really "com.apple.SoftwareUpdate", not just "com". I can get around this by getting that first value separately: NSDictionary *dict = [(NSDictionary *)value valueForKey:@"com.apple.SoftwareUpdate"]; NSNumber *repeatInterval = [dict valueForKeyPath:@"SUCheckSchedulerTag.Timer.repeatInterval"]; I just wanted to know if there is a way to escape periods in a keypath so I can eliminate this extra step.
