  • How to suppress a MongoDDException when proxy can't find a referenced document

    - by Madarco
    We are using Symfony2/DoctrineOdm/MongoDB and when we do: if ($doc.referenceOne != null) { ... } and the $doc.referenceOne contains a MongoDbRef that point to a deleted/lost document, the Doctrine Proxy object raises a MongoDBException. It is possible to tell the Proxy return null instead of raising the exception? Detailed Explanation: Our document: class User { /* @MongoDB\ReferenceOne( ... ) */ private $photo; } If $photo contains a MongoDbRef, but the document is lost/deleted, when we do if ($user.photo) { ... } doctrine will raise a MongoDBException: The "Proxies\DocumentPhotoProxy" document with identifier "4fd8b3ef732bafab7b000000" could not be found We want to suppress the exception since our application can handle null values in that variable. (we could simply log that error, while the exception propagate to a 500 page and disrupt our service)

  • Question in Flex (parser)

    - by shkk
    Hello... I want to ask you a question about Flex, the program for parsing code. Supposing I have an instruction like this one, in the rules part: "=" BEGIN(attribution); <attribution>{var_name} { fprintf(yyout, "="); ECHO; } <attribution>";" BEGIN(INITIAL); {var_name} is a regular expression that matches a variable's name, and all I want to do is to copy at the output all the attribution instructions, such as a = 3; or b = a; My rule though cannot write with fprintf the left member of the attribution, but only = 3; or =a; One solution for that might be that, after I make the match "=" and I am in the attribution state, to go 2 positions back as to get the left operand as well. How can I do that in Flex?

  • How to reset persistent scrollbar position after div refresh in FF3?

    - by rcon
    Hi, I'm experiencing a weird scrollbar issue. I'm building a page that uses jQuery and PHP to dynamically load images into a DIV sequentially. This DIV is a fixed height but uses a scrollbar for its variable width. The problem is that the scrollbar does not reset after a dynamic refresh of the DIV. So when the user scrolls and then refreshes with new content, the scroll bar position stays persistent instead of resetting back to the left. This seems to only happen in FF3. The scrollbar resets perfectly fine in Chrome, Safari, and IE8. For each refresh, the DIV is hidden, emptied, sized with CSS, then sequentially appended with images. I've tried resetting white-space: normal before the nowrap, playing around with overflow, and also jQuery's scrollLeft to no avail. It still behaves strangely in FF3, and only FF3. http://www.shadowshapes.com/uttdev/ Click a thumbnail, move the scrollbar then click another thumb. Thanks for any help!

  • $_SERVER['HTTP_HOST'] not setted

    - by yes123
    Hi guys, I am getting lot of traffic to my php pages but without the variable $_SERVER['HTTP_HOST'] setted. This traffic is like 1 hit per second. I don't know what it could be, but for reducing server load i am doing this at the top of every php pages: if (!isset($_SERVER['HTTP_HOST'])) exit; Do u know what could cause this? Is it safe to exit whenever http_host is not setted? Can a normal user visit my pages without setting http_host? PHP version: 5.2.0-8, Apache: 2.2.3 Thanks

    Ex. typedef struct { bool streamValid; dword dateTime; dword timeStamp; stream_data[800]; } RadioDataA; Ex. Where stream_data[800] contains: **Variable** **Length (in bits)** packetID 8 packetL 8 versionMajor 4 versionMinor 4 radioID 8 etc..

  • In a shared .iml file, what should the jdkName be for an IntelliJ IDEA Plugin SDK?

    - by bolinfest
    I work on a team where we commit our .iml files in version control so that everyone can use them. We have an .iml file for a plugin module, which includes the following: <orderEntry type="jdk" jdkName="IDEA IC-117.798" jdkType="IDEA JDK" /> however, that only works for people who are using that version (IC-117.798) of IntelliJ (some are on 12, some are using the ultimate edition, etc.) Is there any sort of variable like $INTELLIJ_SDK that could be used for the value of jdkName so that the .iml file is valid regardless of which version of IntelliJ you are using?

  • Subtype polymorphism and arrays

    - by user133466
    Computer[] labComputers = new Computer[10]; with public class Computer { ... void toString(){ // print computer specs } } public class Notebook extends Computer{ ... void toString(){ // print computer specs + laptop color } } each subscripted variable labComputers[i] can reference either a Computer object or a Notebook object because Notebook is a subclass of Computer. For the method call labComputers[i].toString(), polymorphism ensures that the correct toString method is called. I wonder what if we do Notebook[] labComputers = new Notebook[10]; what kind or error would I get if I reference with Computer object and a Notebook object

  • How to set a value from another class

    - by Ram
    Its said that property should not be "Set" only and it should be "Get" as well. What should i do if I need to set value to a variable from some other class? The will keep changing so I cannot pass it through constructor. Shall I create a function for this as shown below? class A { public void SetValue() { b = new B(); b.SetTest(10); } } class B { int test; public void SetTest(int value) { test = value; } } What are the other alternatives?

  • How to code the set method of a Map with another Map as value?

    - by Nazgulled
    I normally do this to set a new Map to a private variable: public static void setListaClausulas(Map<String, Clausula> nvLista) { listaClausulas = new TreeMap<String, Clausula>(nvLista); } I suppose this is ok to set a new copy of the nvLista and all it's members and not a reference, is it? But now I have a Map inside another Map and I'm doing this: public static void setListaClausulas(Map<String, Map<String, Clausula>> nvLista) { listaClausulas = new TreeMap<String, Map<String, Clausula>>(nvLista); } Is this the correct way to do it or do you recommend something else? What I want is to set a new copy of nvLista (and all it's elements) and not copy just the reference.

  • Python: Problems finding string in website source code

    - by j00niner
    I open a website with urlopen. I then put the website sourcecode into a variable like so source = website.read() When I just print the source it comes out formatted correctly, however when I try to iterate through each line each character is it's own line. for example when I just print it looks like this <HTML> title</html> When I do this for line in source: print line it looks like this < H T M L ... etc I need to find a string that starts with "var" and then print that entire line.

  • jquery Troubles with binding to an element by id

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • Using try vs if in python

    - by artdanil
    Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value? For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why? result = function(); if (result): for r in result: #process items or result = function(); try: for r in result: #process items except TypeError: pass; Related discussion: Checking for member existence in Python

  • inputMismatchException Java reading doubles from plain text file

    - by user939287
    Using double variable = inputFile.nextDouble(); Gives the mismatch error and I can't figure out why... Anyone know what's up? The input file is just a bunch of doubles like 5.0... Okay here is the code snippet String fileName; Scanner scanner = new Scanner(System.in); System.out.println("\nEnter file name that contains the matrix and vector: "); fileName = scanner.nextLine(); Scanner inputFile = new Scanner(fileName); double a1 = inputFile.nextDouble(); the input file is a plain text document .txt in this format 5.0 4.0 -3.0 4.0 2.0 5.0 6.0 5.0 -2.0 -13.0 4.0 12.0 I don't understand why it wouldn't take those as doubles... As far as what its expecting the format of the file to be... I suppose binary? isn't that the default? I didn't specify in the code...

  • objective-c - calling one constructor from another

    - by synic
    Say you had the following two constructors: - (id)initWithTitle:(NSString *)title; - (id)initWithTitle:(NSString *)title page:(NSString *)page; The second constructor is no different from the first, except that it sets up the member variable "page". Since it basically has to do the same thing, is there a way to call the first one from the second one to reduce code duplication, or do you have to set up a third method to do the common tasks? I'm talking about something similar to this, though I doubt this will work: - (id)initWithTitle:(NSString *)_title { if(self = [super init]) { self.title = _title; } return self; } - (id)initWithTitle:(NSString *)_title page:(NSString *)_page { if(self = [self initWithTitle:_title]) { self.page = _page; } return self; }

  • PhotobucketNet photo upload

    - by n1tr0
    I have a problem with PhotobucketNet user login(I need user to login so I can upload a picture from HDD to his Photobucket account). Photobucket photobucket = new Photobucket("myapikey", "myapisecret"); photobucket.LaunchUserLogin(); // the problem happens here photobucket.RequestUserToken(); If I call RequestUserToken() it will happen immediately, so I'll get a crash cause user didn't logged in, and there is no event that's been raised after user logs in. Is there some variable(bool or something else) that I can check to see if user logged in - maybe to put it in a loop with timer? Also is their a way to know if user canceled logging in? I know that timer isn't a good solution, so if anyone has anything better as an idea, I'm open for any suggestions...

  • Is it possible to apply NOT(!) operator while DataBinding a property of a control ?

    - by Ashish Ashu
    I have Button control and I have to set the IsEanbled property based on the bool variable. bool IsBoolVariable I want if IsBoolVariable property is true then I want to set the IsEnabled property to false AND when IsBoolVariable property is false then I want to set the IsEnabled property to true. Is it possible to apply not(!) operator while defining the binding as given below <Button IsEnabled = "{Binding Path = **!**IsBoolVariable}" /> I can very well do that by applying convertors , but that is the only way to do that?

  • pthread_exit return value

    - by Manty
    This is surprising for me. void * thread_func(void *arg) { pthread_exit(&ret); } int main(void) { pthread_t thr; int *exit_status; pthread_create(&thr, NULL, thread_func, NULL); sleep(2); pthread_join(thr, (void **)&exit_status); printf("value of exit status - %d\n", *exit_status); ret = 20; pthread_join(thr, (void **)&exit_status); printf("value of exit status - %d\n", *exit_status); return 0; } The output is value of exit status - 50 value of exit status - 20 I was expecting both the times the exit_status would be the actual exit value(50 in my case) of the thread. Instead it is just returning the value of the global variable which I used for pthread_exit. Is it not a bug?

  • Why does Generic class signature requires specifying new() if type T needs instantiation ?

    - by this. __curious_geek
    I'm writing a Generic class as following. public class Foo<T> : where T : Bar, new() { public void MethodInFoo() { T _t = new T(); } } As you can see the object(_t) of type T is instantiated at run-time. To support instantiation of generic type T, language forces me to put new() in the class signature. I'd agree to this if Bar is an abstract class but why does it need to be so if Bar standard non-abstract class with public parameter-less constructor. compiler prompts following message if new() is not found. Cannot create an instance of the variable type 'T' because it does not have the new() constraint

  • Interesting XSL Dilemma

    - by bobber205
    I've got this issue. A template called "checkbox" that's called from while inside a table HTML element and also outside of it. To solve an issue, I've added tags to "checkbox" input control. Here's what I'd like to do to but I'm not sure if it's possible or not. When I hit my "row" (part of the custom table markup) template, I would set some variable or pass some parameter, that for each template applied afterwards, would know it was in a "row" and do something special based on this information. I know I can't add parameters to apply-templates. I may be able to add a row "mode" but I can't make changes to each template and have one copy with the mod parameter and one without. Thanks for any suggestions. I know the ideal solution would to be to make changes to the XML but I'm not sure if I can do that as this point. That's a "content" issue. :P Thanks!

  • Wordpress Custom Type permalink containing Taxonomy slug

    - by treznik
    I'm trying to create a permalink pattern for a Custom Type, that includes one of its taxonomies. The taxonomy name is known from the start (so I'm not trying to add or mix all of its taxonomies, just a specific one), but the value will by dynamic, of course. Normally, the Custom Type permalink is built using the rewrite arg with the slug param, but I don't see how I could add a dynamic variable in there. http://codex.wordpress.org/Function_Reference/register_post_type I'm guessing a custom solution is required, but I'm not sure what the best unintrusive approach would be. Is there a known practice for this or has anyone built something similar recently? I'm using WP 3.2.1 btw.

  • Easy way to cast an object array into another type in C#

    - by Na7coldwater
    I want to be able to be able to quickly cast an array of objects to a different type, such as String, but the following code doesn't work: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); String[] c = (String[]) b.ToArray(); And I don't want to have to do this: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); Object[] temp = b.ToArray(); Object[] temp = b.ToArray(); String[] c = new String[temp.Length]; for(int i=0;i<temp.Length;i++) { c[i] = (String) temp[i]; } Is there an easy way to do this without using a temporary variable?

  • What is a good rule for when to prepend members with 'this' (C#)?

    - by RichAmberale
    If I am accessing a member field, property, or method, I'm never sure when I should prepend it with 'this'. I am not asking about cases where it is required, like in the case where a local variable has the same name. I am talking about cases where the meaning is exactly the same. Which is more readable? Are there any standards, best practices, or rules of thumb I should be following? Should it just be consistent throughout a class, or an entire code base?
