  • Opening Another Xib form an Xib

    - by Goods
    Not a Noob as yesterday, but still green. I have been playing around with the code that Elisabeth Robson has put together HERE. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I put a 'Learn More' button on the current xib(BookDetailView). I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Ive Tried IBAction and Pushing the Newer xib to the top. Do I need to create another view controller? Thanks for looking.

  • CakePHP form $options['options']

    - by James
    Hey! Total CakePHP noob here. This is sort of a two fold question. In a view that is used for adding user objects I would like to use a drop down (selection) field in the form. Each user belongs to a group so when I add a user I want a drop down that contains all of the groups that the user could possibly join. Currently the group_id field is a textfield. I know how to force it to be a selection field, but I don't know how to populate the selection with the names of the groups programmatically. The Current method: echo $form->input('group_id', array( '1' => 'NameOfGroup1', '2' => 'NameOfGroup2', '3' => 'NameOfGroup3') ); I want to generate the options array programmatically though. echo $form->input('group_id', $this->Group->find('list')); This doesn't work though. I get an error: Undefined property: View::$Group [APP/views/users/add.ctp, line 8] To me this means that I don't have access to the Group object from inside my user view. How can I accomplish this? Again, I want to do it programmatically so that it updates as I add groups or remove them.

  • How to update a table row with save button using .ajax

    - by Randall
    I have a table which has one row and only one cell will be editable. I have accomplished this with the following code. $("td#effEndDate").click(function() { if (!$(this).hasClass("edit")) { var value = jQuery.trim($(this).html()); $(this).html("<input id=\"txtEdit\" type=\"text\" value=\"" + value + "\" />"); $(this).addClass("edit"); $("#txtEdit").focus(); } }); Now this is the part where i'm stuck. After the field is updated a save button must be clicked to call the proper .ajax method to update the database. But how can I compare the previous value to the current value on a button press? Since i'm not using the onblur property where I could have saved the old value and passed it to the update function.

  • Slide in the second tab bar view by clicking on item in the first

    - by Henrik Erlandsson
    I have an app with three tabs that switch views instantaneously when the user taps them. The first view is a table view selecting which 'location type' to filter by, to only show those pins (add those annotations) to the second view, a MapView. When a table cell is clicked, it switches instantaneously to the mapview, using this code: self.tabBarController.selectedIndex=1; However, I would like to do this with a slide-in-from-right animation, like the one you get when drilling down a hierarchy of table views. I tried this: [self.navigationController pushViewController:[self.tabBarController.viewControllers objectAtIndex:1] animated:YES]; which compiles without error or warning, but does not switch views. How do I 'apply' a navigation controller 'onto' a tab bar controller? Or is there some way to select another viewcontroller and specify an animation?

  • How should I implement lazy session creation in PHP?

    - by Adam Franco
    By default, PHP's session handling mechanisms set a session cookie header and store a session even if there is no data in the session. If no data is set in the session then I don't want a Set-Cookie header sent to the client in the response and I don't want an empty session record stored on the server. If data is added to $_SESSION, then the normal behavior should continue. My goal is to implement lazy session creation behavior of the sort that Drupal 7 and Pressflow where no session is stored (or session cookie header sent) unless data is added to the $_SESSION array during application execution. The point of this behavior is to allow reverse proxies such as Varnish to cache and serve anonymous traffic while letting authenticated requests pass through to Apache/PHP. Varnish (or another proxy-server) is configured to pass through any requests without cookies, assuming correctly that if a cookie exists then the request is for a particular client. I have ported the session handling code from Pressflow that uses session_set_save_handler() and overrides the implementation of session_write() to check for data in the $_SESSION array before saving and will write this up as library and add an answer here if this is the best/only route to take. My Question: While I can implement a fully custom session_set_save_handler() system, is there an easier way to get this lazy session creation behavior in a relatively generic way that would be transparent to most applications?

  • Loop with a while

    - by ookla
    Very basic question.. but I'm missing the point.. I have this data on my table: ID SITEID SECTION 1 1 posts 2 2 posts 3 1 aboutme 4 1 contact 5 2 questions The output is an array. I can't change it. I want to make this output on php with a single for loop with that array: <h1> sections for site 1 </h1> posts aboutme contact <h1>sections for site 2 </h1> posts questions I'm trying to do something like this, where $sectionsArray is my output. And I want to check if siteid is the same, then make a loop.. for ($j=0;$j<sizeof($sectionsArray);$j++) { while (siteid==1){ echo "<h1>'.$sectionsArray['siteid'].'</h1>'; } echo "<A href='section.php?id='.$sectionsArray['id'].' '">'.$sectionsArray['section'].'</a>; } But I don't get the logic of "grouping" the results with a while.. INSIDE a loop. Any light will be welcome. Thanks

  • In Java, howd do I iterate through lines in a textfile from back to front

    - by rogue780
    Basically I need to take a text file such as : Fred Bernie Henry and be able to read them from the file in the order of Henry Bernie Fred The actual file I'm reading from is 30MB and it would be a less than perfect solution to read the whole file, split it into an array, reverse the array and then go from there. It takes way too long. My specific goal is to find the first occurrence of a string (in this case it's "InitGame") and then return the position beginning of the beginning of that line. I did something like this in python before. My method was to seek to the end of the file - 1024, then read lines until I get to the end, then seek another 1024 from my previous starting point and, by using tell(), I would stop when I got to the previous starting point. So I would read those blocks backwards from the end of the file until I found the text I was looking for. So far, I'm having a heck of a time doing this in Java. Any help would be greatly appreciated and if you live near Baltimore it may even end up with you getting some fresh baked cookies. Thanks!

  • possible xml elements in Android resources xmls ?

    - by Vijay C
    I recently came across a forum post in thelink text android developers group. (link below) It has one post which contains following xml. It is xml file which can be used in drawable folder. <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- Non focused states --> <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected" /> <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected" /> <!-- Focused states --> <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_focus" /> <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_focus"/> <!-- Pressed --> <item android:state_pressed="true" android:drawable="@drawable/tab_press" /> </selector> Now my question is, where is the documentation which tells me that i can use the following xml tags <selector> , <item>, <color>, <integer-array>, <string-array> and many others tag to create xml resources...? I hope, i have explained what i want to know ?

  • How do I set the next available custom color in the ColorDialog?

    - by Hannah
    I'm currently coding in VB.net. A user places the cursor in a table cell and clicks on "Table Background Color" to edit the current background colour. Currently I have been able to detect the current colour (for instance a light blue) and set that colour in the ColorDialog (Colour swatches are correct and RGB values are correct). What I would like to do is enable the user to click on the "Add to Custom Colors" to save the colour. Problem is, it sets the first square in the custom colours area (which happens to already be filled in with another custom colour), rather than finding the next square that is white and set it there instead. Is this possible? If the user selects a new custom colour square when they first load the ColorDialog, the current colour (light blue) disappears and the colour swatches and RGB values are set as white. Thanks

  • Parsing multibyte string in PHP

    - by Petr Peller
    I would like to write a (HTML) parser based on state machine but I have doubts how to acctually read/use an input. I decided to load the whole input into one string and then work with it as with an array and hold its index as current parsing position. There would be no problems with single-byte encoding, but in multi-byte encoding each value does not represent a character, but a byte of a character. Example: $mb_string = 'žšcr'; //4 multi-byte characters in UTF-8 for($i=0; $i < 4; $i++) { echo $mb_string[$i], PHP_EOL; } Outputs: L ž L A This means I cannot iterate through the string in a loop to check single characters, because I never know if I am in the middle of an character or not. So the questions are: How do I multi-byte safe read a single character from a string in a performance friendly way? Is it good idea to work with the string as it was an array in this case? How would you read the input?

  • JTable.setRowHeight prevents me from adding more rows

    - by Brent Parker
    I'm working on a pretty simple Java app in order to learn more about JTables, TableModels, and custom cell renderers. The table is a simple table with 8 columns only with text in them. When you click on an "add" button, a dialog pops up and lets you enter the data for the columns. Now to my problem. One of the columns (the last one) should allow for multiple lines of text. I'm already putting HTML into the field, but it is not wrapping. I did some research and looked into JTable#setRowHeight(). However, once I use setRowHeight, I can no longer add rows to the table. The data is put into the table model, but it does not show in the table. If I remove the setRowHeight line, then it adds data just fine. Is there another step to adding data to my data model that I'm missing? Thanks a lot!

  • Strange Ruby String Selection

    - by Daniel
    The string in question (read from a file): if (true) then { _this = createVehicle ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; _vehicle_10 = _this; _this setDir -2.109278; }; Retrieved from a large list of similar (all same file) strings via the following: get_stringR(string,"if","};") And the function code: def get_stringR(a,b,c) b = a.index(b) b ||= 0 c = a.rindex(c) c ||= b r = a[b,c] return r end As so far, this works fine, but what I wanted to do is select the array after "createVehicle", the following (I thought) should work. newstring = get_string(myString,"\[","\];") Note get_string is the same as get_stringR, except it uses the first occurrence of the pattern both times, rather then the first and last occurrence. The output should have been: ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; Instead it was the below, given via 'puts': ["Land_hut10", [6226.8901, 986.091, 4.5776367e-005], [], 0, "CAN_COLLIDE"]; _vehicle_10 = _this; _this setDir Some 40 characters past the point it should have retrieve, which was very strange... Second note, using both get_string and get_stringR produced the exact same result with the parameters given. I then decided to add the following to my get_string code: b = a.index(b) b ||= 0 c = a.index(c) c ||= b if c 40 then c -= 40 end r = a[b,c] return r And it works as expected (for every 'block' in the file, even though the strings after that array are not identical in any way), but something obviously isn't right :).

  • how to write barcode in html format when using tcpdf

    - by JewelThief
    I am using TCPDF to generate PDF file using following command $pdf-writeHTML($htmlcontent, true, 0, true, 0); TCPDF also provides a way to create barcode with following commands $pdf-Cell(0, 0, 'C39+', 0, 1); $pdf-write1DBarcode('Code 39', 'C39+', '', '', 80, 15, 0.4, $style, 'N'); $pdf-Ln(); I want to be able to write barcode as part of the HTML code above. Is there easy way? I can potentially call a barcode image inthe writeHTML code above, but not sure how to use above barcode function ( or any in TCPDF) which would allow me to create image and then get that image into HTML generation

  • Tinyurl API Example - Am i doing it right :D

    - by Paul Weber
    Hi ... we use super-long Hashes for the Registration of new Users in our Application. The Problem is that these Hashes break in some Email Clients - making the Links unusable. I tried implementing the Tinyurl - API, with a simple Call, but i think it times out sometimes ... sometimes the mail does not reach the user. I updated the Code, but now the URL is never converted. Is Tinyurl really so slow or am i doing something wrong? (I mean hey, 5 Seconds is much in this Times) Can anybody recommend me a more reliable service? All my Fault, forgot a false in the fopen. But i will leave this sample of code here, because i often see this sample, wich i think does not work very reliable: return file_get_contents('http://tinyurl.com/api-create.php?url='.$u); This is the - i think fully working sample. I would like to hear about Improvements. static function gettinyurl( $url ) { $context = stream_context_create( array( 'http' => array( 'timeout' => 5 // 5 Seconds should be enough ) ) ); // get tiny url via api-create.php $fp = fopen( 'http://tinyurl.com/api-create.php?url='.$url, 'r', $context); // open (read) api-create.php with long url as get parameter if( $fp ) { // check if open was ok $tinyurl = fgets( $fp ); // read response if( $tinyurl && !empty($tinyurl) ) // check if response is ok $url = $tinyurl; // set response as url fclose( $fp ); // close connection } // return return $url; // return (tiny) url }

  • How to loop video using NetStream in Data Generation Mode

    - by WesleyJohnson
    I'm using a NetStream in Data Generation Mode to play an embeded FLV using appendBytes. When the stream is finished playing, I'd like to loop the FLV file. I'm not sure how to achieve this. Here is what I have so far (this isn't a complete example): public function createBorderAnimation():void { // Load the skin image borderAnimation = Assets.BorderAnimation; // Convert the animation to a byte array borderAnimationBytes = new borderAnimation(); // Initialize the net connection border_nc = new NetConnection(); border_nc.connect( null ); // Initialize the net stream border_ns = new NetStream( border_nc ); border_ns.client = { onMetaData:function( obj:Object ):void{ trace(obj); } } border_ns.addEventListener( NetStatusEvent.NET_STATUS, border_netStatusHandler ); border_ns.play( null ); border_ns.appendBytes( borderAnimationBytes ); // Initialize the animation border_vd = new Video( 1024, 768 ); border_vd.attachNetStream( border_ns ); // Add the animation to the stage ui = new UIComponent(); ui.addChild( DisplayObject( border_vd ) ); grpBackground.addElement( ui ); } protected function border_netStatusHandler( event:NetStatusEvent ):void { if( event.info.code == "NetStream.Buffer.Flush" || event.info.code == "NetStream.Buffer.Empty" ) { border_ns.appendBytesAction( NetStreamAppendBytesAction.RESET_BEGIN ); border_ns.appendBytes( borderAnimationBytes ); border_ns.appendBytesAction( NetStreamAppendBytesAction.END_SEQUENCE ); } } This will loop the animation, but it starts chewing up memory like crazy. I've tried using NetStream.seek(0) and NetStream.appendBytesAction( NetStreamAppendBytesAction.RESET_SEEK ), but then I'm not sure what to do next. If you just try to call appendBytes again after that, it doesn't work, presumably because I'm appending the full byte array which has the FLV header and stuff? I'm not very familiar with how that all works. Any help is greatly appreciated.

  • Why my UTableView with style UITableViewStyleGrouped is consuming memory?

    - by prathumca
    Hello everyone, Currently in my app, I'm using an UITableView with style UITableViewStyleGrouped as shown below. CGRect imgFrame = CGRectMake(0, 0, 320, 650); UITableView *myTable = [[UITableView alloc] initWithFrame:imgFrame style:UITableViewStyleGrouped]; myTable.dataSource = self; myTable.delegate = self; //make the current object the event handler for view [self.view addSubview:myTable]; [myTable release]; And the data has stored in an array "dataArray". dataArray has collection of arrays, where each array represent a section. Currently I have only one section with 100 records. When I installed my app onto my IPhone, I observed that this UITableView is consuming 20 MB of IPhone memory. If I changed the table view style to "UITableViewStylePlain", then it is consuming only 4MB of memory. I'm trying to figure it out, where is the exact problem, but not. What was wrong with "UITableViewStyleGrouped"? Regards, prathumca.

  • LotusScript - Setting element in for loop

    - by Kris.Mitchell
    I have an array set up Dim managerList(1 To 50, 1 To 100) As String what I am trying to do, is set the first, second, and third elements in the row managerList(index,1) = tempManagerName managerList(index,2) = tempIdeaNumber managerList(index,3) = 1 But get an error when I try to do that saying that the object variable is not set. I maintain index as an integer, and the value corresponds to a single manager, but I can't seem to manually set the third element. The first and second elements set correctly. On the flip side, I have the following code that will allow for the element to be set, For x=1 To 50 If StrConv(tempManagerName,3) = managerList(x,1) Then found = x For y=3 to 100 If managerList(x,y) = "" Then managerList(x,y) = tempIdeaNumber Exit for End If Next Exit For End If Next It spins through the array (laterally) trying to find an empty element. Ideally I would like to set the index of the element the y variable is on into the 3rd element in the row, to keep a count of how many ideas are on the row. What is the best way to keep a count like this? Any idea why I am getting a Object variable not set error when I try to manually set the element?

  • PHP Loop Over ONLY Different Arrays

    - by Steven
    Hello, I have a single array with several of the same values. And I only want to loop over DIFFERENT values. How could I go about doing this? Example 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO; 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108 166-01 001;09;UO;_86_97_108_119 166-01 001;09;UO;_86_97_108_119 I have that in a single array, but I only want to loop for the different ones. So it would loop once for nothing, then once for _86, then once for _86_97, then once for _86_97_108, and then once for _86-97_108_119. So only loop for different key values, or would there be a way to count the number of different keys?

  • Reading email address from contacts fails with weird memory issue

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on?

  • Help Needed With AJAX Script

    - by Brian
    Hello All I am working on an AJAX script but am having difficulties. First, here is the script: var xmlHttp; function GetXmlHttpObject(){ var objXMLHttp=null if (window.XMLHttpRequest){ objXMLHttp=new XMLHttpRequest() } else if (window.ActiveXObject){ objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP") } return objXMLHttp } function retrieveData(){ var jBossServer = new Array(); jBossServer[0] = "d01"; jBossServer[1] = "d02"; jBossServer[2] = "p01"; jBossServer[3] = "p02"; for(var i=0; i<jBossServer.length; i++){ xmlHttp = GetXmlHttpObject(); if (xmlHttp == null){ alert ("Something weird happened ..."); return; } var url="./retrieveData.php"; url = url + "?jBossID=" + jBossServer[i]; url = url + "&sid=" + Math.random(); xmlHttp.open("GET",url,true); xmlHttp.onreadystatechange = updateMemory; xmlHttp.send(null); } } function updateMemory(){ if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete"){ aggregateArray = new Array(); aggregateArray = xmlHttp.responseText.split(','); for(var i=0; i<aggregateArray.length; i++){ alert(aggregateArray[i]); } return; } } The "retrieveData.php" page will return data that looks like this: d01,1 MB,2 MB,3 MB They relate to my 4 servers d01, d02, p01, and p02 (dev and prod). What I am doing is scraping the memory information from http://127.0.0.1:8080/web-console/ServerInfo.jsp I want to save code so I attempted to put the AJAX xmlHttp call into a loop, but I don't think it is working. All I ever get back is the information for "p02" four times. Am I able to do what I want or do I need four different functions for each server (i.e., xmlHttpServer01, xmlHttpServer02, xmlHttpServer03, xmlHttpServer04)?

  • NSMutable String "Out of scope"

    - by Garry
    I have two NSMutableString objects defined in my viewController's (a subclass of UITableViewController) .h file: NSMutableString *firstName; NSMutableString *lastName; They are properties: @property (nonatomic, retain) NSMutableString *firstName; @property (nonatomic, retain) NSMutableString *lastName; I synthesis them in the .m file. In my viewDidLoad method - I set them to be blank strings: firstName = [NSMutableString stringWithString:@""]; lastName = [NSMutableString stringWithString:@""]; firstName and lastName can be altered by the user. In my cellForRowAtIndexPath method, I'm trying to display the contents of these strings: cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ %@", firstName, lastName]; but this is causing the app to crash as soon as the view controller is displayed. Using the debugger, it seems that both firstName and lastName are "out of scope" or that they don't exist. I'm new to Xcode but the debugger seems to halt at objc_msgSend. What am I doing wrong?

  • High performance text file parsing in .net

    - by diamandiev
    Here is the situation: I am making a small prog to parse server log files. I tested it with a log file with several thousand requests (between 10000 - 20000 don't know exactly) What i have to do is to load the log text files into memory so that i can query them. This is taking the most resources. The methods that take the most cpu time are those (worst culprits first): string.split - splits the line values into a array of values string.contains - checking if the user agent contains a specific agent string. (determine browser ID) string.tolower - various purposes streamreader.readline - to read the log file line by line. string.startswith - determine if line is a column definition line or a line with values there were some others that i was able to replace. For example the dictionary getter was taking lots of resources too. Which i had not expected since its a dictionary and should have its keys indexed. I replaced it with a multidimensional array and saved some cpu time. Now i am running on a fast dual core and the total time it takes to load the file i mentioned is about 1 sec. Now this is really bad. Imagine a site that has tens of thousands of visits a day. It's going to take minutes to load the log file. So what are my alternatives? If any, cause i think this is just a .net limitation and i can't do much about it.
