  • UIImage for UIImageView is nil

    - by yeesterbunny
    I'm having problem displaying UIImage in UIImageView. I looked all over stackoverflow for similar questions, but none of the fixes helped me. The image is indeed in my bundle File Inspector - Target Membership is checked for the image IBOutlet is connected (I have tried both using IBOutlet and doing it programmatically) Both png nor jpg works Here's the code for using Interface Builder - //@property and @synthesize set for IBOutlet UIImageView *imageView - (void)viewDidLoad { [super viewDidLoad]; NSAssert(self.imageView, @"self.imageView is nil. Check your IBOutlet connection"); UIImage *image = [UIImage imageNamed:@"banner.jpg"]; NSAssert(image, @"image is nil"); self.imageView.image = image; } This code will terminate with NSAssert, printing in the console that 'image is nil'. I also tried selecting the Image directly from the attributes inspector: However it still doesn't show the image (still terminates with NSAssert - 'image is nil'). Any help or suggestions will be greatly appreciated. Thanks

  • Log4Perl - how to set exit code if any WARN, ERROR, or FATAL messages?

    - by pdxrlk
    Hi - I've been using Log4Perl extensively in a number of scripts. I'd like to augment those scripts to set an error code if any WARN or ERROR messages have been logged. I couldn't find any obvious way to do this based on existing documentation. I'd like to avoid a brute-force rewrite of my existing scripts to add a check on every WARN or ERROR log message; I'd prefer to handle it prior to script exit if possible like this pseudocode: if $log->has_warnings_or_errors then exit 1 else exit 0 Is there any easy way to call Log4Perl to determine if the current logger has issues messages of certain levels? Thanks.

  • How to use the merge command

    - by Vaccano
    Say I have a table called Employee (has ID, NAME, ADDRESS, and PHONE columns). (Not my real problem, but simplified to make the question easier.) If I call a sproc called UpdateEmployee and I pass in a @Name, @Address, @Phone and @ID. Can merge be used to easily check to see if the ID exists? If it does to update the name, address and phone? and if it does not to insert them? I see examples on the net, but they are huge and hairy. I would like a nice simple example if possible. (We recently upgraded to SQL 2008, so I am new to the merge command.)

  • How can I determine new & previous cell value on SheetChange event in Excel?

    - by Falco Foxburr
    I have some special cells in my Excel workbooks which are managed by my Excel Add-in. I want to prevent users from changing content of those cells, but I also want to know, what value users wanted to enter to those cells. On the SheetChange event I can check what users entered to my special cells, but how do I determine the PREVIOUS value in those cells and REVERT user changes? It is not a solution for me. If I lock cell in Excel, it becomes read-only - user can not even try to enter anything to this cell - Excel popups warning dialog in this case. My problem is that I want to catch what user entered to my cell, do something with this value, and then revert cell content to original value.

  • How to handle un-assigned records

    - by Mico
    I have this PHP page where the user can select and un-select items. The interface looks like this: Now I'm using these code, when the user hit the save changes button: foreach( $value as $al_id ){ //al_id is actually location id //check if a record exists //if location were assigned and leave it as is $assigned_count = $this->AssignedLoc->checkIfAssigned( $tab_user_id, $al_id ); if( $assigned_count == 0 ){ //else if not, insert this new record $this->insertAssigned( $tab_user_id, $company_id, $al_id ); } } Now my question is, how do I delete the un assigned locations? For example in the screenshot above, there are 4 assigned locations, if I'm gonna remove (or unassign) "Mercury Morong" and "GP Hagonoy" from the assigned locations, only two must remain. What are the possible solutions using PHP? Thanks for any help!

  • Can code formatting lead to change in object file content?

    - by kumar
    I have run though a code formatting tool to my c++ files. It is supposed to make only formatting changes. Now when I built my code, I see that size of object file for some source files have changed. Since my files are very big and tool has changed almost every line, I dont know whether it has done something disastrous. Now i am worried to check in this code to repo as it might lead to runtime error due to formatting tool. My question is , will the size of object file be changed , if code formatting is changed.?

  • MYSQL to UPDATE table if row with 2 specific columns exist or INSERT new row if it does not exist

    - by user2509541
    I have a MYSQL table that looks as follows: id id_jugador id_partido team1 team2 1 2 1 5 2 2 2 2 1 1 3 1 2 0 0 I need to create a query to either INSERT new rows in the table or UPDATE the table. The condition is based on id_jugador and id_partido, meaning that if I wanted to insert id_jugador = 2 and id_partido = 1, then it should just UPDATE the existing row with the new team1 and team2 values I am sending. And dont duplicate the row. However, if I have an entry id_jugador=2 and id_partido=3, since this combination does not exist yet, it should add the new row. I read about the REPLACE INTO but it seems to be unable to check combination of UNIQUE KEYS.

  • Beginner SQL question(s)

    - by unit
    I am two months in to an intro sql course, it's late at night, and I am drawing a blank. I have two tables, one customers, and one orders. I have to increase any customers credit limit by twenty five percent for all customers who have made two or more orders in which each order is more than the amount of 250.00. I get how to UPDATE CreditLimit * 1.25 and Cust with an order 250, but how the hell do I get it to check if they have made two orders over 250? Second question, we are just starting to take subqueries, and I am having a difficult time getting it into my skull. Another question posed by the prof of our class is to increase the credit limit of a customer who has an order that exceeds their credit limit. (Credit limit is on a customers table, order and amount are on an orders table). I then take that customer and UPDATE his CreditLimit +1000. Thanks for any help.

  • Strings - Filling In Leading Zeros Wtih A Zero

    - by headscratch
    I'm reading an array of hard-coded strings of numeric characters - all positions are filled with a character, even for the leading zeros. Thus, can confidently parse it using substring(start, end) to convert to numeric. Example: "0123 0456 0789" However, a string coming from a database does not fill in the leading zero with a 'zero character', it simply fetches the '123 456 789', which is correct for an arithmetic number but not for my needs and makes for parsing trouble. Before writing conditionals to check for leading zeros and adding them to the string if needed, is there a simple way of specifying they be filled with a character ? I'm not finding this in my Java book... I could have done the three conditionals in the time it took to post this but, this is more about 'education'... Thanks

  • How to authenticate a user using SQL

    - by Tom
    I have an DLL which is constantly connected to a SQL Server instance. The server itself is connected with "admin" permissions, but "normal" users should be able to access the server with their own username and password. The server would still be connected a "admin". I just want to check if the user can access the database. Is there a way to authenticate the user using a SQL query? It would of course be possible to add a encrypted "password" column to a database table for users, but I would prefer not having to do that.

  • How to do a random-and-unique generator?

    - by javaLearner.java
    I already wrote a random generator which take arguments a and b, where a is minimun and b is maximum value, like this randomGenerator(int a, int b) What I want to do next is: Using a loop, then generate unique number from a to b. Example: I want to have 8 unique numbers, int a = 1; int b = 10; int value; If I do the loop, there is a high % that same number will appear more than once. Any idea how to do it? My own way is: while(int i <= 8){ randomGenerator(a,b); // if value is not in array, then insert into array } I am stuck at the comment part. Is there any way to check if a variable is exists in an array?

  • Is there a way to optimise finding text items on a page (not regex)

    - by Jeepstone
    After seeing several threads rubbishing the regexp method of finding a term to match within an HTML document, I've used the Simple HTML DOM PHP parser (http://simplehtmldom.sourceforge.net/) to get the bits of text I'm after, but I want to know if my code is optimal. It feels like I'm looping too many times. Is there a way to optimise the following loop? //Get the HTML and look at the text nodes $html = str_get_html($buffer); //First we match the <body> tag as we don't want to change the <head> items foreach($html->find('body') as $body) { //Then we get the text nodes, rather than any HTML foreach($body->find('text') as $text) { //Then we match each term foreach ($terms as $term) { //Match to the terms within the text nodes $text->outertext = str_replace($term, '<span class="highlight">'.$term.'</span>', $text->outertext); } } } For example, would it make a difference to determine check if I have any matches before I start the loop maybe?

  • Using TFS source control - how to remove files

    - by arame3333
    I am a lone developer, and I am now using TFS 2010, having until recently used VSS. I have not found it easy to get any books for beginners to help me use this. So I have now got my project in source control. But when I check in I get references to a number of files that I no longer use. How do I remove files from the TFS Source Control repository? So in the example below you can see lots of files from different projects that I do not want to see.

  • Password Hash Implementation

    - by oyerli
    I am developing a new application using Symfony. I want to store the passwords hashed, so I overridded the save method in my User model: public function save(Doctrine_Connection $conn = null) { $this->setUserPassword( md5($this->getUserPassword()) ); return parent::save($conn); } This works good when a new user created. However, this causes problems when we edit a user without changing his password. This causes Doctrine to hash the already hashed password. So, I need to check that whether the UserPassword is modified in this DoctrineRecord instance. How can I manage to do that?

  • Use jQuery to match variable text?

    - by VUELA
    Hello! I have a sidebar navigation that lists blog entry titles down the side of the page. I am trying to write some jquery that will check the text in the title of the current full blog entry page and match it with the corresponding title in the sidebar navigation so that I can apply a class to style for an active state link ... but I'm not quite getting it! Here is the link to an example page: http://ncw-commercial.com/property-listings/eastpoint-plaza-lot.html, and below is my current code. I have also tried using :contains but could not figure out how to get that to work with a variable rather than direct text. $('.single-journal-entry-wrapper .journal-entry .title').each(function(){ var activeTitle = $(this).text(); $(".feedburnerFeedBlock .headline a").filter(function(index) { return $(this).text() == "activeTitle"; }).parent().addClass("activeTitle"); });

  • Template apps for iPhone

    - by rob
    Is there a good place to get starter apps for iPhone, where you choose from any of a large set of permutations?...for instance with a nav bar and a flip screen and a 3 deep table view, with Core Data support etc. I guess what I was hoping for is some kind of wizard where you can check a few boxes and have a working app as a starting point....but more than just the 3 or 4 choices that come with xCode. If not a wizard, just a nice set of a couple dozen permutations. Also....is there any good sample apps out there that show the difference between identical apps, one which uses Interface Builder and one not? Aside from being handy for myself, I'd think these would be great as a teaching tool. I've googled a bit and come up with nothing.

  • Hash passwords before transmitting? (web)

    - by wag2639
    I was reading this Ars article on password security and it mentioned there are sites that "hash the password before transmitting"? Now, assuming this isn't using an SSL connection (HTTPS), a. is this actually secure and b. if it is how would you do this in a secure manor? Edit 1: (some thoughts based on first few answers) c. If you do hash the password before transmission, how do you use that if you only store a salted hash version of the password in your user credentials databas? d. Just to check, if you are using a HTTPS secured connection, is any of this necessary?

  • Is there an alternative of using a VBScript for enabling FileStream after SQL Server installation?

    - by user193655
    To use Filestream on a DB 3 steps must be done: 1) enable it a server/instance level 2) enable it (sp_configure) at DB level 3) create a varbinary(max) field that supports filestream (2) and (3) are done easily with T-SQL (1) is doable manually from SQL Server Configuration Manager, basically what I need is to check all the 3 checkboxes: but how is it possible to automize it? I found this artcile "Enabling filestream usin a VBScript", is there another way to do it than using VBScripts? May be something that is possible to do only with 2008R2? In case it VBScript is the only solution, which are the possible downsides?

  • Does the Internet make us less good programmers? [closed]

    - by stagas
    With all the information and code available nowadays on the Internet has that diminished our capability of remembering or learning stuff just because we know they're available somewhere out there, just a Google away or a StackOverflow question away? For example I find myself visiting php.net quite often to check the syntax of the same functions over and over again, not because my memory sucks, but I don't feel like keeping the information in me, since I know I'll find it again on the net. And about StackOverflow, isn't the process of figuring things out on your own supposed to improve your programming skills? If the answers are all just clicks away, do we actually learn something or just keep a pointer in our heads where to search for it again when we need it? Your thoughts are welcome. Hope it doesn't shut down as subjective or anything, the answers would be really interesting ;)

  • What is the worst source control you have used? [closed]

    - by David Liddle
    There are many discussions about what people's favourite source control is (subversion, mercurial ...). But what source control systems have you used that you certainly wouldn't recommend? And more beneficial, how would you go about promoting change in the business to a new source control system? A few years ago I developed using a source control system called Synergy. There were two Synergy experts in the company that constantly had to help the developers do check-ins/outs and merges were especially difficult. What would be your steps of migrating to a better source control. Would you host everything internally or pay for services such as github?

  • In Spring MVC, is it possible to have different return types in one request handler method?

    - by Bobo
    For example, if a request succeeds, I will return a View ,if not, return a String indicating error message and set the content-type to either xml or json. Based on what I read, seems like I should use "void" as the return type for handler methods. Check this out: "void if the method handles the response itself (by writing the response content directly, declaring an argument of type ServletResponse / HttpServletResponse for that purpose) or if the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)."(Spring Framework reference). What I dont understand is what " the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)" means? Any anyone give me an example?
