• iOS 5 fixed positioning and virtual keyboard

  - by jeffc

  I have a mobile website which has a div pinned to the bottom of the screen via position:fixed. All works fine in iOS 5 (I'm testing on an iPod Touch) until I'm on a page with a form. When I tap into an input field and the virtual keyboard appears, suddenly the fixed position of my div is lost. The div now scrolls with the page as long as the keyboard is visible. Once I click Done to close the keyboard, the div reverts to its position at the bottom of the screen and obeys the position:fixed rule. Has anyone else experienced this sort of behavior? Is this expected? Thanks.

• Verify windows log-in via smart card

  - by Ronen Rabinovitz

  Hi I need to verify in my WPF application if the user log in to his computer via password or via smart-card. Both login options are available in my company clients but my application need to open only in the smart-card login. All the clients are windows 7 OS. I look at some sites: http://technet.microsoft.com/en-us/library/ff404285(v=ws.10).aspx http://www.codeproject.com/Articles/240655/Using-a-Smart-Card-Certificate-with-NET-Security-i and I'm thinking I need to get the enhanced key usage (EKU) attribute field. If the EKU is empty = then the user was loged via password and not via smartcard. I only need this simple check, I do not care for creating/validations on certificates atc.

  - by Win Coder

  A Group of objects. However i am having confusion in the following case.

• Does flex not support hashmaps?

  - by Dr.Dredel

  I have a Flex object which collects a DTO from the server. All the fields arrive filled in correctly except for the one that is a HashMap. It arrives as null. I've tried giving it a type of both ArrayCollection and Dictionary, but that hasn't fixed it. Does anyone know if there's an inherent incomaptability between Java HashMap and Flex? If not, what might I be doing wrong here? I'm looking at my jboss console and I see the data being populated correctly in the server side before delivery to the client. However, as it gets to the client, that field is null. I'm ready to kill myself.

• MYSQL - Help with a more complicated Query

  - by Joe

  I have two tables: tbl_lists and tbl_houses Inside tbl_lists I have a field called HousesList - it contains the ID's for several houses in the following format: 1# 2# 4# 51# 3# I need to be able to select the mysql fields from tbl_houses WHERE ID = any of those ID's in the list. More specifically, I need to SELECT SUM(tbl_houses.HouseValue) WHERE tbl_houses.ID IN tbl_lists.HousesList -- and I want to do this select to return the SUM for several rows in tbl_lists. Anyone can help? I'm thinking of how I can do this in a SINGLE query since I don't want to do any mysql "loops" (within PHP).

• Grouping with operands question

  - by Filip

  I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

• SQLite multi process access

  - by Nicolas

  Hello, We are using SQLite in a multi processes and multi threaded application. The SQLite database files are encrypted using the embedded SQLite encryption. The FAQ states that SQLite should be able to manage multi process accesses using locks mechanism. We are experiencing a strange problem: When many threads are accessing the same database file, sometime constrains violations occur, more specifically - a field with a unique constrain is getting duplicate values after calling "insert or replace" statement. It happens quite often now, that we are using the encryption. Before we started using SQLite encryption we did not notice such a behavior. Are there any specific known issues with this?

• Make is more OOPey - good structure?

  - by Tom

  Hi, I just want advice on whether I could improve structure around a particular class which handles all disk access functions The structure of my program is that I have a class called Disk which gets data from flatfiles and databases on a, you guessed it, hard disk drive. I have functions like LoadTextFileToStringList, WriteStringToTextFile, DeleteLineInTextFile etc which are kind of "generic methods" In the same class I also have some more specific methods such as GetXFromDisk where X might be a particular field in a database table/query. Should I separate out the generic methods from the specialised. Should I make another class which inherits the generic methods. At the moment my class is static as there is no need to have an internal state of the class. I'm not really OOPing am I? Thanks Thomas

• Can MYSQL filter by date if date is stored as text? ex "02/10/1984"

  - by Roeland

  Hello! I am trying to modify an app for a client which has already a database of over 1000 items. The dates are stored as text in the database with the format "02/10/1984". The system allows you to add and remove fields to the catalog dynamically and it also allows the advanced search to have specific fields be allowed. The problem is that it wasn't designed with dates in mind, so when I set a field as a date, and try to search by a range the query is trying to do a AND (cfv0.value = 01/02/2004 AND cfv0.value <= 05/03/2008) . I can make it so the date range passed is a numeric time value. Is there a way that when sending the query, it takes the text fields (with the date) and converts it to numeric time value so at that point I am basically just comparing numbers which would work fine. I do not have the option to change all the current date to numeric value due to the way the dynamic fields are set up. Thanks guys!

• cakephp filter index pages according to foreign keys

  - by Marki

  Hi there, I'm pretty new to CakePHP and was missing a crucial feature not generated as scaffold: filtering. What do I have to do to provide dropdowns or multi-selects on the index pages for each field that is a (foreign) key, thereby allowing to filter the table ("OR" inside multi-select, "AND" between different multi-selects, if any)? From what my websearch has shown me there are many more people trying to accomplish the same thing, although I couldn't find anything that would work for me because either they have text fields and do wildcard filtering, or the plugins they propose only work for 1.2 whereas i now started with 1.3 etc. etc. Can someone alleviate the confusion and maybe present some working code or direct me to the definitive guide[tm] where this matter has been solved? Thx

• Correct Way to Get Date Between Dates In SQL Server

  - by Chuck Haines

  I have a table in SQL server which has a DATETIME field called Date_Printed. I am trying to get all records in the table which lie between a specified date range. Currently I am using the following SQL DECLARE @StartDate DATETIME DECLARE @EndDate DATETIME SET @StartDate = '2010-01-01' SET @EndDate = '2010-06-18 12:59:59 PM' SELECT * FROM table WHERE Date_Printed BETWEEN @StartDate AND @EndDate I have an index on the Date_Printed column. I was wondering if this is the best way to get the rows in the table which lie between those date or if there is a faster way. The table has about 750,000 records in it right now and it will continue to grow. The query is pretty fast but I'd like to make it faster if possible.

• How do you change the subdocument location in a Word 2007 master document programmatically?

  - by boost

  We have had the unenviable happen: various master documents refer to sub-documents that are no longer where they used to be due to a directory renaming. Is there a programmatic way of tweaking the HYPERLINK field without losing the master/sub-document relationship? I've got this far ... Sub FixyaLinks() Dim s 'As String Dim i As Long Dim bTrackRevFlag As Boolean Dim bShowRevFlag As Boolean bTrackRevFlag = ActiveDocument.TrackRevisions bShowRevFlag = ActiveDocument.ShowRevisions ActiveDocument.TrackRevisions = False ActiveDocument.ShowRevisions = False For i = 1 To ActiveDocument.Fields.Count s = ActiveDocument.Fields.Item(i).Code.Text If InStr(s, "CURRICULUM\\NEW") Then s = Replace(s, "NEW Foundation Units-in developing", "Foundation Programme Units") ActiveDocument.Fields.Item(i).Code.Text = s End If Next ActiveDocument.TrackRevisions = bTrackRevFlag ActiveDocument.ShowRevisions = bShowRevFlag End Sub It bombs on ActiveDocument.Fields.Item(i).Code.Text = s, with an error 5686 ("The operation cannot be completed because the Track Changes option in the master document does not match the option the the subdocument. Make the Track Changes option the same in the master document and subdocument.") However, I'm not entirely sure what that means. Ideas anyone?

• iPhone: Best Method for Passing Data to and from a Server

  - by SAPNA

  I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.

• jQuery Plugin Overwriting Parameters

  - by Travis

  Hey Everyone, This maybe a very mundane question, but this is the first jQuery plugin that I write and I'm a bit fuzzy on understanding the scope rules in Javascript. I'm trying to write an simple jQuery plugin that wraps around the Stack Overflow API. I'm starting off by trying to work with the Flair API. I wanted to make the plugin as configurable as possible so that you can easily pass it the domain and user id, and generate multiple Flairs. var superUser = $.jStackOverflow.flair({domain:"superuser.com", id: 30162, parentId:'#su-flair'}); var stackOverflow = $.jStackOverflow.flair({domain:"stackoverflow.com", id: 55954, parentId:'#so-flair'}); The problem is, when it makes the second call, its somehow using the correct domain and id parameters, but the parentId field that it's using in the callback function to create the html, is using the first parameter. You can see the plugin here and the html here

• Why packets injected with libpcap are duplicated?

  - by r0u1i

  I'm using sharppcap in order to send packets as part of a monitoring system. Usually it works well but I've encountered the strangest bug on a hosted vista machine and I would like your help. On that virtual vista machine, injected packets are duplicated. That is, if I send a ping request using libpcap, it somehow gets duplicated and I get two requests on the destination machine. The two requests are almost identical byte-wise, and the only difference between them is that the second packet's TTL field is one minus the original packet's value. Using wireshark I can see the packet gets duplicated before it (and its clone) leave the vista machine. The problem is manifested even when using other tools for injecting packets using libpcap (namely PlayCap). Any ideas?

• How can I accept a hash mark in a URL via $_GET?

  - by bccarlso

  From what I have been able to understand, hash marks (#) aren't sent to the server, so it doesn't seem likely that I will be able to use raw PHP to parse data like in the URL below: index.php?name=Ben&address=101 S 10th St Suite #301 I'm looking to pre-populate form fields with this $_GET data. How would I do this with Javascript (or jQuery), and is there a fallback that wouldn't break my form for people not using Javascript? Currently if there is a hash (usually in the address field), everything after that is not parsed in or stored in $_GET.

• Wicket : Can a Panel or Component react on a form submit without any boilerplate code?

  - by MRalwasser

  I am currently evaluating Wicket and I am trying to figure out how things work. I have a question regarding form submit and panels (or other components). Imagine a custom wicket panel which contains a text field, doing as-you-type validation using ajax. This panel is added to a form. How can the Panel react a form submit (let's say because javascript/ajax is unavailable)? I am currently only aware of one solution: calling a panel's method inside the Form onSubmit() method. But this seems not like a "reusable" approach here, because I have to add boilerplate code to every form's onSubmit() which contains the panel (and every developer which use the panel must know this). So here comes my question: Is there any way that a Panel/Component can "detect" a form submit in some way? Or is there any other solution beside this? Thank you.

• Automatically compute variable upon input in SPSS

  - by what

  I have two cells in SPSS, months is a number of months, years_from_months is the number of years, calculated from the months (decimal: months / 12). What I want is that years_from_months is calculated (and updated) automatically, when I finish entering the months in months, i.e. that I don't have to explicitly call compute manually through the menu. I have defined years_from_months to calculate the years, but at the moment the field only updates when I go to the menu option Transform Compute variable ... and click OK in the window that opens. How can I set up the cell to update automatically (like in Excel)?

• Returning partial address matches and mismatch position using L2S or SQL

  - by peter3

  I need to implement a method that takes an address split up into individual parts and returns any matching items from an address table. If no matches are found, I want to be able to return a value indicating where it failed. Each input param has a corresponding field in the table. The signature would look something like this: List<Address> MatchAddress(string zipCode, string streetName, string houseNumber, string houseLetter, string floor, string appartmentNo, out int mismatchPosition) { // return matching addresses // if none found, return the position where it stopped matching // zipCode is position 0, appartmentNo is position 5 // // an empty param value indicates "don't check" } I know I can construct the method such that I start with all the parameters, execute the query and then remove param by param (from the right side) until either a match is found or I run out of parameters, but can I construct a query that is more effective than that, i.e minimizing the number of calls to the db, maybe even as a single call?

• Ajax data two-way data binding strategies?

  - by morgancodes

  I'd like to 1) Draw create form fields and populate them with data from javascript objects 2) Update those backing objects whenever the value of the form field changes Number 1 is easy. I have a few js template systems I've been using that work quite nicely. Number 2 may require a bit of thought. A quick google search on "ajax data binding" turned up a few systems which seem basically one-way. They're designed to update a UI based on backing js objects, but don't seem to address the question of how to update those backing objects when changes are made to the UI. Can anyone recommend any libraries which will do this for me? It's something I can write myself without too much trouble, but if this question has already been thought through, I'd rather not duplicate the work.
