  • c# combobox autocomplete like method

    - by Willem T
    Ihave been looking for an LIKE autocompletion mode. can anyone help me with this. When i enter a text in the combobox, the database should be asked for the data. all that goes well. But then i want my combobox to behave like the Suggest mode, but it doesn't work. I Tried this: cursorPosition = txtNaam.SelectionStart; string query = "SELECT bedr_naam FROM tblbedrijf WHERE bedr_naam LIKE '%" + txtNaam.Text + "%'"; DataTable table = Global.db.Select(query); txtNaam.Items.Clear(); for (int i = 0; i < table.Rows.Count; i++) { txtNaam.Items.Add(table.Rows[i][0].ToString()); } Cursor.Current = Cursors.Default; txtNaam.Select(cursorPosition, 0); But the behavior that this function creates is off it doesnt work like the suggest mode its a bit buggy. Can anyone help me to get it working properly Thanks

  • Counting character count in Access database column ins SQL

    - by jzr
    Good Evening. My problem is possibly very easy, I just have spent some time researching now and probably have a brain lock and unable to solve this, help would be much appreciated. database structure: col1 col2 col3 col4 ==================== 1233+4566+ABCD+CDEF 1233+4566+ACD1+CDEF 1233+4566+D1AF+CDEF I need to count character count in col3, wanted result in from the previous table would be: char count =========== A 3 B 1 C 2 D 3 F 1 1 2 is this possible to achieve by using SQL only? at the moment I am thinking of passing a parameter in to SQL query and count the characters one by one and then sum, however I did not start the VBA part yet, and frankly wouldn't want to do that. this is my query at the moment: PARAMETERS X Long; SELECT First(Mid(TABLE.col3,X,1)) AS [col3 Field], Count(Mid(TABLE.col3,X,1)) AS Dcount FROM TEST GROUP BY Mid(TABLE.col3,X,1) HAVING (((Count(Mid([TABLE].[col3],[X],1)))>=1)); ideas and help are much appreciated, as being said this is probably very for some of your guys, I don't usually work with access and SQL. Thanks.

  • Database solution for 200million writes/day, monthly summarization queries

    - by sb
    Hello. I'm looking for help deciding on which database system to use. (I've been googling and reading for the past few hours; it now seems worthwhile to ask for help from someone with firsthand knowledge.) I need to log around 200 million rows (or more) per 8 hour workday to a database, then perform weekly/monthly/yearly summary queries on that data. The summary queries would be for collecting data for things like billing statements, eg. "How many transactions of type A did each user run this month?" (could be more complex, but that's the general idea). I can spread the database amongst several machines, as necessary, but I don't think I can take old data offline. I'll definitely need to be able to query a month's worth of data, maybe a year. These queries would be for my own use, and wouldn't need to be generated in real-time for an end-user (they could run overnight, if needed). Does anyone have any suggestions as to which databases would be a good fit? P.S. Cassandra looks like it would have no problem handling the writes, but what about the huge monthly table scans? Is anyone familiar with Cassandra/Hadoop MapReduce performance?

  • MonoTouch's Soft Debugger don't connect to App on iPhone - why?

    - by smokinharp
    Hi everyone, I'm quite new on MonoTouch, so please forgive me my question in doubt... ;-) I need help with the soft-debugger, because it's not connecting to the App on the device. While with iPhone Simulator everything is working as expected, the following happens when I start debugging against my device: The is uploaded and installed to the device. MonoDevelop comes up with a window saying the following: "Waiting for debugger to connect on 127.0.0.1:10000..." Please start the application on the device" When starting the app on the device, the device vibrates indicating that the debugger is not connected.... In the settings of my App on the iPhone I have set the IP-Adress to my Mac's IP. My iPhone is connected via WIFI to my network. I can ping my Mac from my iPhone and vice versa. In several screenshots where the debugger was obviously working I saw that the debugger came up with the Mac's IP address and not the 127.0.0.1.... Do I have to configure my IP-address somewhere in MonoDevelop? BTW: I'm using the latest version of MonoDevelop - it's 2.4.1 I have tried anything.... re-installing MonoDevelop, cleaning up the project several times, setting up a new project.... nothing... Please, please help....

  • calling a trim method in actionscript 2.0

    - by user151013
    Hi I Got a notnull function for a text field as below private function valStringNotNull( val:String ) :Boolean { if ( String(val).length <= 0 ) { _errorCode = "StringNull"; return false; } _errorCode = "NoError"; return true; } and this function is being called here var pCnt:Number = 0; _validateParams[pCnt++] = { type: "notNull", input: win.firstNameInput , isSendData:true, dataName:"firstName"}; _validateParams[pCnt++] = { type: "notNull", input: win.lastNameInput, isSendData:true, dataName:"lastName"}; _validateParams[pCnt++] = { type: "noValidation", input: roleCombo, isSendData:true, dataName:"role" }; Selection.setFocus(win.firstNameInput); and for the not null I defined this way private function validateCases ( param:Object ) :Boolean { _errorObj = param.input || param.input1; switch( param.type ) { case "notNull": return valStringNotNull( param.input.text ); break; } } but as you see as I defined the length should be greater than zero its taking even a space as an input and displaying blank white space in my text field so I got a trim function as below public function ltrim(input:String):String { var size:Number = input.length; for(var i:Number = 0; i < size; i++) { if(input.charCodeAt(i) > 32) { return input.substring(i); } } return ""; } and I need to call this trim function before my not null function so that it trims off all the leftside white space but as I am very new to flash can some one help me how to keep this trim function before the notnull function.Can some one please help me with this please

  • How to calculate Content-Length for a file download within Kohana PHP?

    - by moritzd
    I'm trying to send a file from within a Kohana model to the browser, but as soon as I add a Content-Length header, the file doesn't start downloading right away. Now the problem seems to be that Kohana is already outputting buffers. An ob_clean at the begin of the script doesn't help this though. Also adding ob_get_length() to the Content-Length isn't helping since this just returns 0. The getFileSize() function returns the right number: if I run the script outside of Kohana, it works. I read that exit() still calls all destructors and it might be that something is outputted by Kohana afterwards, but I can't find out what exactly. Hope someone can help me out here... This is the piece of code I'm using: public function download() { header("Expires: ".gmdate("D, d M Y H:i:s",time()+(3600*7))." GMT\n"); header("Content-Type: ".$this->getFileType()."\n"); header("Content-Transfer-Encoding: binary\n"); header("Last-Modified: " . gmdate("D, d M Y H:i:s",$this->getCreateTime()) . " GMT\n"); header("Content-Length: ".($this->getFileSize()+ob_get_length().";\n"); header('Content-Disposition: attachment; filename="'.basename($this->getFileName())."\"\n\n"); ob_end_flush(); readfile($this->getFilePath()); exit(); }

  • My HTML5 web app crashes and I have no clue how to debug

    - by Shouvik
    Hi All, I have written a word game using HTML5 canvas tag and a little bit of audio. I developed the application on the chrome web browser on a linux system. Recently during the testing phase it was tried on safari 5.0.3 on Mac and the webpage froze. Not just the canvas element, but interactive element on the page froze. I have at some times experienced this problem on google chrome when I was developing but since the console did not throw any error before this happened, I did not give it much credence. Now as per requirements I am supposed to support both chrome and safari but this dismal performance on safari has left me shocked and I cannot see what error can be thrown which might lead to such a situation. Worse yet the CPU usage on using this application peaks to 70-80percent on my 2yr old macbook running ubuntu... I can only but pity the person who uses mac to operate this app, which undoubtedly is a heavier OS. Could someone help me out with a place I can start with to find out what exactly is causing this issue. I have run profiles on this webapp on google chromes console and noticed that in the heap spanshot value increases steadily with the playing of the game, specifically (root) value which jumps up by 900 counts. Any help would be very appreciated! Thanks EDIT: I don't know if this helps, but I have noticed that even on refreshing the page after the app becomes unresponsive the page reloads and I am still not able to interact with the page elements but the tab scroll bar continues to work and I can see my application window completely. So to summaries the tab stops accepting any sort of user interaction inside the page. Edit2: Nop. It doesn't work still... The app crashes on double click on the canvas element. The console is not throwing any errors either! =/ I have noticed this problem is isolated only to safari!

  • Change jQuery slider option dynamically based on window width

    - by Nathan
    I would like to change a jQuery option based on window width (on load as well as on resize). I've found solutions close to what I need, but I don't understand jQuery or javascript enough to customize them for my needs. Here's my jQuery code: <script type="text/javascript"> var tpj = jQuery; tpj.noConflict(); tpj(document).ready(function () { if (tpj.fn.cssOriginal != undefined) tpj.fn.css = tpj.fn.cssOriginal; tpj('#rev_slider_1_1').show().revolution({ delay: 5000, startwidth: 1920, startheight: 515, hideThumbs: 200, thumbWidth: 100, thumbHeight: 50, thumbAmount: 4, navigationType: "bullet", navigationArrows: "verticalcentered", navigationStyle: "navbar", touchenabled: "on", onHoverStop: "off", navOffsetHorizontal: 0, navOffsetVertical: 20, shadow: 0, fullWidth: "on" }); }); //ready </script> I want to change the startheight based on window width. If the window width is above 1280 I would like the value for the height to be 515, and if it is below 1280 I would like the height to be 615 and if the width is less than 480 make the height 715. With help from another post I am able to change the css I need using this script: $(window).on('load resize', function () { var w = $(window).width(); $("#rev_slider_1_1 #rev_slider_1_1_wrapper") .css('max-height', w > 1280 ? 515 : w > 480 ? 615 : 715); }); But I need to also change the jQuery startheight value on the fly. Can someone help? Thanks!

  • how to pass vector of string to foo(char const *const *const)?

    - by user347208
    Hi, This is my first post so please be nice. I searched in this forum and googled but I still can not find the answer. This problem has bothered me for more than a day, so please give me some help. Thank you. I need to pass a vector of string to a library function foo(char const *const *const). I can not pass the &Vec[0] since it's a pointer to a string. Therefore, I have an array and pass the c_str() to that array. The following is my code (aNames is the vector of string): const char* aR[aNames.size()]; std::transform(aNames.begin(), aNames.end(), aR, boost::bind(&std::string::c_str, _1)); foo(aR); However, it seems it causes some undefined behavior: If I run the above code, then the function foo throw some warnings about illegal characters ('èI' blablabla) in aR. If I print aR before function foo like this: std::copy(aR, aR+rowNames.size(), std::ostream_iterator<const char*>(std::cout, "\n")); foo(aR); Then, everything is fine. My questions are: Does the conversion causes undefined behavior? If so, why? What is the correct way to pass vector of string to foo(char const *const *const)? Thank you very much for your help!

  • Timestamps and Intervals: NUMTOYMINTERVAL SYSTDATE CALCULATION SQL QUERY

    - by MeachamRob
    I am working on a homework problem, I'm close but need some help with a data conversion I think. Or sysdate - start_date calculation The question is: Using the EX schema, write a SELECT statement that retrieves the date_id and start_date from the Date_Sample table (format below), followed by a column named Years_and_Months_Since_Start that uses an interval function to retrieve the number of years and months that have elapsed between the start_date and the sysdate. (Your values will vary based on the date you do this lab.) Display only the records with start dates having the month and day equal to Feb 28 (of any year). DATE_ID START_DATE YEARS_AND_MONTHS_SINCE_START 2 Sunday , February 28, 1999 13-8 4 Monday , February 28, 2005 7-8 5 Tuesday , February 28, 2006 6-8 Our EX schema that refers to this question is simply a Date_Sample Table with two columns: DATE_ID NUMBER NOT Null START_DATE DATE I Have written this code: SELECT date_id, TO_CHAR(start_date, 'Day, MONTH DD, YYYY') AS start_date , NUMTOYMINTERVAL((SYSDATE - start_date), 'YEAR') AS years_and_months_since_start FROM date_sample WHERE TO_CHAR(start_date, 'MM/DD') = '02/28'; But my Years and months since start column is not working properly. It's getting very high numbers for years and months when the date calculated is from 1999-ish. ie, it should be 13-8 and I'm getting 5027-2 so I know it's not correct. I used NUMTOYMINTERVAL, which should be correct, but don't think the sysdate-start_date is working. Data Type for start_date is simply date. I tried ROUND but maybe need some help to get it right. Something is wrong with my calculation and trying to figure out how to get the correct interval there. Not sure if I have provided enough information to everyone but I will let you know if I figure it out before you do. It's a question from Murach's Oracle and SQL/PL book, chapter 17 if anyone else is trying to learn that chapter. Page 559.

  • How would I sort files to directories based on filenames?

    - by gnomed
    I have a huge number of files to sort all named in some terrible convention. Here are some examples: (4)_mr__mcloughlin____.txt 12__sir_john_farr____.txt (b)mr__chope____.txt dame_elaine_kellett-bowman____.txt dr__blackburn______.txt These names are supposed to be a different person (speaker) each. Someone in another IT department produced these from a ton of XML files using some script but the naming is unfathomably stupid as you can see. I need to sort literally tens of thousands of these files with multiple files of text for each person; each with something stupid making the filename different, be it more underscores or some random number. They need to be sorted by speaker. This would be easier with a script to do most of the work then I could just go back and merge folders that should be under the same name or whatever. There are a number of ways I was thinking about doing this. parse the names from each file and sort them into folders for each unique name. get a list of all the unique names from the filenames, then look through this simplified list of unique names for similar ones and ask me whether they are the same, and once it has determined this it will sort them all accordingly. I plan on using Perl, but I can try a new language if it's worth it. I'm not sure how to go about reading in each filename in a directory one at a time into a string for parsing into an actual name. I'm not completely sure how to parse with regex in perl either, but that might be googleable. For the sorting, I was just gonna use the shell command: `cp filename.txt /example/destination/filename.txt` but just cause that's all I know so it's easiest. I dont even have a pseudocode idea of what im going to do either so if someone knows the best sequence of actions, im all ears. I guess I am looking for a lot of help, I am open to any suggestions. Many many many thanks to anyone who can help. B.

  • Windows service (hosting WCF service) stops immediately on start up

    - by Thr33Dii
    My Question: I cannot navigate to the base address once the service is installed because the service won't remain running (stops immediately). Is there anything I need to do on the server or my machine to make the baseAddress valid? Background: I'm trying to learn how to use WCF services hosted in Windows Services. I have read several tutorials on how to accomplish this and it seems very straight forward. I've looked at this MSDN article and built it step-by-step. I can install the service on my machine and on a server, but when I start the service, it stops immediately. I then found this tutorial, which is essentially the same thing, but it contains some clients that consume the WCF service. I downloaded the source code, compiled, installed, but when I started the service, it stopped immediately. Searching SO, I found a possible solution that said to define the baseAddress when instantiating the ServiceHost, but that didnt help either. My serviceHost is defined as: serviceHost = new ServiceHost( typeof( CalculatorService ), new Uri( "http://localhost:8000/ServiceModelSamples/service" ) ); My service name, base address, and endpoint: <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="CalculatorServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:8000/ServiceModelSamples/service"/> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> I've verified the namespaces are identical. It's just getting frustrating that the tutorials seem to assume that the Windows service will start as long as all the stated steps are followed. I'm missing something and it's probably right in front of me. Please help!

  • Obtaining XML from U.S. Postal Service (USPS) rate calculator API with PHP

    - by Chris F
    hoping somebody here can help me. I'm attempting to pull an XML page from the U.S. Postal Service (USPS) rate calculator, using PHP. Here is the code I am using (with my API login and password replaced of course): <? $api = "http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4Request ". "USERID=\"MYUSERID\" PASSWORD=\"MYPASSWORD\"><Revision/><Package ID=\"1ST\">". "<Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType>". "<ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination>". "<Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request>"; $xml_string = file_get_contents($api); $xml = simplexml_load_string($xml_string); ?> Pretty straightforward. However it never returns anything. I can paste the URL directly into my browser's address bar: http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4RequestUSERID="MYUSERID" PASSWORD="MYPASSWORD"><Revision/><Package ID="1ST"><Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType><ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination><Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request> And it returns the XML I need, so I know the URL is valid. But I cannot seem to capture it using PHP. Any help would be tremendously appreciated. Thanks in advance.

  • C++ Type error with Object versus Object reference

    - by muddybruin
    I have the following function (which worked in Visual Studio): bool Plane::contains(Vector& point){ return normalVector.dotProduct(point - position) < -doubleResolution; } When I compile it using g++ version 4.1.2 , I get the following error: Plane.cpp: In member function âvirtual bool Plane::contains(Vector&)â: Plane.cpp:36: error: no matching function for call to âVector::dotProduct(Vector)â Vector.h:19: note: candidates are: double Vector::dotProduct(Vector&) So as you can see, the compiler thinks (point-position) is a Vector but it's expecting Vector&. What's the best way to fix this? I verified that this works: Vector temp = point-position; return normalVector.dotProduct(temp) < -doubleResolution; But I was hoping for something a little bit cleaner. I heard a suggestion that adding a copy constructor might help. So I added a copy constructor to Vector (see below), but it didn't help. Vector.h: Vector(const Vector& other); Vector.cpp: Vector::Vector(const Vector& other) :x(other.x), y(other.y), z(other.z), homogenous(other.homogenous) { }

  • Export to csv, string w/ comma in it, splits it up

    - by Brad
    This code exports data into a csv file, which is opened within Excel. When a string has a comma within it, it messes up the order of the data. I need help modifying my code below to resolve any data that contains a comma within it, to not to create a new column. I am assuming it will pass each string within double quotes, so any comma within those quotes, then it will make an exception. Any help is appreciated. $result = mysql_query("select lname, fname, email, dtelephone, etelephone, contactwhen, comments, thursday, friday, saturday, sunday, monday FROM volunteers_2010"); $csv_output .= "Last Name,First Name,Email,Telephone (Day),Telephone (Evening),Contact When,Comments,Thursday,Friday,Saturday,Sunday,Monday,Comments\n"; $i = 0; if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { $csv_output .= $row['Field'].", "; $i++; } } $csv_output .= "\n"; $values = mysql_query("SELECT lname, fname, email, dtelephone, etelephone, contactwhen, comments, thursday, friday, saturday, sunday, monday FROM volunteers_2010 WHERE venue_id = $venue_id"); while ($rowr = mysql_fetch_row($values)) { for ($j=0;$j<$i;$j++) { $csv_output .= $rowr[$j].", "; } $csv_output .= "\n"; }

  • Regex preg_match issue with commas

    - by Serge Sf
    This is my code to pre_match when an amount looks like this: $ 99.00 and it works if (preg_match_all('/[$]\s\d+(\.\d+)?/', $tout, $matches)) { $tot2 = $matches[0]; $tot2 = preg_replace("/\\\$/", '', $tot2);} I need to do the same thing for a amount that looks like this (with a comma): $ 99,00 Thank you for your help (changing dot for comma do not help, there is an "escape" thing I do not understand... Idealy I need to preg_match any number that looks like an amount with dot or commas and with or without dollar sign before or after (I know, it's a lot to ask :) since on the result form I want to scan there are phone and street numbers... UPDATE (For some reason I cannot comment on replies) : To test properly, I need to preg_replace the comma by a dot (since we are dealings with sums, I don't think calculations can be done on numbers with commas in it). So to clarify my question, I should say : I need to transform, let's say "$ 200,24" to "200.24". (could be amounts bettween 0.10 to 1000.99) : $tot2 = preg_replace("/\\\$/", '', $tot2);} (this code just deals with the $ (it works), I need adaptation to deal also with the change of (,) for (.))

  • filtering search results with php

    - by fl3x7
    Hello, Cant really find any useful information on this through Google so hope someone here with some knowledge can help. I have a set of results which are pulled from a multi dimensional array. Currently the array key is the price of a product whilst the item contains another array which contains all the product details. key=>Item(name=>test, foo=>bar) So currently when I list the items I just order by the key, smallest first and it lists the products smallest price first. However I want to build on this so that when a user sees the results they can choose other ordering options like list all products by a name, certain manufacturer, colour, x ,y ,z etc etc from a drop down box(or something similar) This is where I need some guidance. Im just not sure how to go about it or best practise or anything. The only way I can think of is to order all the items by the nested array eg by the name, manufacturer etc. but how do I do that in PHP? Hope you understand what im trying to achieve(if not just ask). Any help on this with ideas, approaches or examples would be great. Thanks for reading p.s Im using PHP5

  • Syntax Problems of if Statement (php)

    - by MxmastaMills
    I need a little help with an if statement in php. I'm trying to set a variable called offset according to a page that I am loading in WordPress. Here's the variable: $offset = ($paged * 6); What it does is it loads the first page, which is: http://example.com/blog and $offset is thus set to 0 because $paged is referring to the appending number on the URL. The second page, for example is: http://example.com/blog/2/ which makes $offset set to 12. The problem is, I need the second page to define $offset as 6, the third page to define $offset as 12, etc. I tried using: $offset = ($paged * 6 - 6) which works except on the first page. On the first page it defines $offset as -6. SO, I wanted to create an if statement that says if $paged is equal to 0 then $offset is equal to 0, else $offset is equal to ($paged * 6 - 6). I struggle with syntax, even though I understand what needs to be done here. Any help would be greatly appreciated. Thanks!

  • zend studio 5.5.1 on windows xp - won't open!

    - by esther h
    I have been using zend studio 5.5.1 for the last year and and a half (on windows xp), with some occasional issues, such as a blank error dialog box when I started the program, but always went away when i restarted my computer, and usually got messages about javaw.exe errors. But now, the program does not open at all. What happens is, I get a little dialog that says Loading project - this is normal... but then, nothing. The zend program item is sitting in the taskbar, but when i click on it - nothing! there is nothing to show. i can right click and press close, but that is all. restarting computer did not help. i just uninstalled it, downloaded again from zend website, and reinstalled. tried opening - get loading box, seems to have loaded, even got tip of the day box. but there is nothing showing behind them. once i closed the tip box, i dont have any indication that zend is open besides the program item in the taskbar. windows task manager says it is running... anyone have a clue? help!!! thanks

  • System.Threading.Timer won't trigger

    - by mijatovic
    Hello guys, I am new here... I have one question, if somebody can help me. It is about timers (System.Threading.Timer). I want to break inevitable recursion: I have two columns in datarow and they are mutually dependant (price_without_VAT and price_with_VAT). Setting one of them will definitely cause StackOverflowException. So here's the idea: bool flag = true; void Reset(object state) { flag = true; } Now, wrap the method for changing value of one of the columns: { if(flag) { flag = false; System.Threading.Timer tmr = new System.Threading.Timer(new System.Threading.TimerCallback(Reset), null, 10, System.Threading.Timeout.Infinite); datarow.other_column = value; } } datarow.other_column.value line will immediately trigger the above method, but there will be no recursion because flag is false. In 10 ms flag should be back to true, and everything is back to normal. Now, when i follow the code in DEBUGGER, everything works fine, but when I start app NORMALLY Reset function simply will not trigger, flag is stuck to false forever and everything false apart. I play around with due_time parameter but nothing seems to help. Any ideas?

  • Array of Sentences?

    - by user1869915
    Javascript noob here.... I am trying to build a site that will help my kids read predefined sentences from a select group, then when a button is clicked it will display one of the sentences. Is an array the best option for this? For example, I have this array (below) and on the click of a button I would like one of these sentences to appear on the page. <script type="text/javascript"> Sentence = new Array() Sentence[0]='Can we go to the park.'; Sentence[1]='Where is the orange cat? Said the big black dog.'; Sentence[2]='We can make the bird fly away if we jump on something.' Sentence[3]='We can go down to the store with the dog. It is not too far away.' Sentence[4]='My big yellow cat ate the little black bird.' Sentence[5]='I like to read my book at school.' Sentence[6]='We are going to swim at the park.' </script> Again, is an array the best for this and how could I get the sentence to display? Ideally I would want the button to randomly select one of these sentences but just displaying one of them for now would help. Thanks

  • How can I create dynamically updated views in a tab bar view, based on settings selection?

    - by Diggers
    Hi all, Noob question.... I've created a Tab Bar application. It has four tabs and works fine. Each view is created with a XIB and is effectively static. Each view takes user input and responds on screen. What I need to be able to do is change the input options the user have - in effect remove some UITextFields dependant upon which option the user selects in settings. I've created root.plist and created settings no problem i've also created additional XIBS for the altered UI, but what I don't know how to do, is call these into the tab view controller on demand. Effectively tab one has 3 possible views, tab two 3 possible views etc. But I only want the one that's relevant for the users settings selction to be displayed? Make sense? For reference, if we call the different views - UIInputViewA1, ...A2,....A3 UIInputViewB1,....B2....B3 etc. Hope someone can help, been trawling the net for nights trying to get my head round this. Beggining iPhone Development Bible doesn't help either. If you need any more info, please shout. Cheers Paul.
