  • Cookie Value not available, why?

    - by Camran
    I have tested this on my development computer, but now I have uploaded everything to the production server and I cant read out the value of the cookie. I think the problem lies in the Serialization and Unserialization. if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; //20 days $ad_arr = unserialize($_COOKIE['watched_ads']); // HERE IS THE PROBLEM $arr_elem = count($ad_arr); if (in_array($ad_id, $ad_arr) == FALSE){ if ($arr_elem>10){ array_shift($ad_arr); } $ad_arr[]=$ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } When I echo this: count($ad_arr) I receive the expected nr, 1 in this case, so there is a value there. But when I echo the value: echo $ad_arr[0]; I get nothing. Completely blank. No text at all. Anybody have a clue? if you need more info about something let me know...

  • Grabbing an HTML value with JSF

    - by user560785
    Hi everyone! I have a javascript that edits a hidden field in my jsf page: <h:inputHidden id="data" value="" /> and when I click on "Submit" I would like to get the new value of this HTML field that was modified by the javascript. I've looked into FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("data"); But that seems only to work if it is passed in as an <f:param/>. Is there a way i can get the value through a bean call?

    - by user544079
    I have the following form which is getting pre populated with values on load. I want to have empty input boxes on load using Javascript. However I do not have access to the <body> tag so <body onload="" will not work here. Is there any other way to clear the form fields on load? <form method="POST" action=""> <input name="username" id="user" value="" /><br /> <input name="pwd" id="pass" value="" /> <input type="submit" value="Go" /> </form>

  • Rails -- Cant set value for date_select in form

    - by ChrisWesAllen
    I'm pulling data from an API where the date data comes in as "2008-02-11 00:00:00 " I would like that data to go into my form within the date_select as a value so I can view it correctly before I add it into my database. The view looks like <%= f.label :start_date %><br /> <%= f.date_select :start_date, :value => " #{@stdate[idx]} " %> The object is actually an array of dates since I'm doing this action several times do thats why the [idx] is there; serving as an index. <%= @stdate[idx] % ends up outputting "2008-02-11 00:00:00 " but the fields for the date_select helper only outputs the current date "2010" "June" "5" in those dropdown date selects fields... Do I need to set the values of the Year, Month, and Date Individually? I have Chronic and tried to parse the object before using it as a value for the date_select and that didnt work either. Any ideas?

  • How are value types implemented in .NET

    - by Michael
    Been looking around the net and can't find any articles about how value types are actually implemented. For instance, an Int32 is a struct and it's direct parent is System.ValueType and that's ultimate parent is System.Object. Object is a class - I imagine ValueType is a class? What's the class hierarchy? What part does the CLR have to play? At what stage and how does the CLR know to allocate value types to the stack? (FYI, I am aware that value types are stored where they are declared).

  • WPF TextBox value doesn't change on OnPropertyChanged

    - by jpsstavares
    I have a TextBox whose Value is binded to a ViewModel property: <TextBox Name="txtRunAfter" Grid.Column="4" Text="{Binding Mode=TwoWay, Path=RunAfter}" Style="{StaticResource TestStepTextBox}"/> The set and get were working fine until I tried to add some validation when the Value is set: private int _runAfter = 0; public string RunAfter { get { return _runAfter.ToString(); } set { int val = int.Parse(value); if (_runAfter != val) { if (val < _order) _runAfter = val; else { _runAfter = 0; OnPropertyChanged("RunAfter"); } } } } Although the OnPropertyChanged is reached (I have dubugged that), the View is not changed. How can I make this work? Thanks, José Tavares

  • How to copy an object by value, not by reference

    - by Blankman
    I want to make a copy of an object, then after some logic, re-assign the original object the value of the copy. example: User userCopy = //make a copy foreach(...) { user.Age = 1; user.ID = -1; UserDao.Update(user) user = userCopy; } I don't want a copy by reference, it has to be a copy by value. The above is just a sample, not how I really want to use it but I need to learn how to copy by value.

  • Return Integer value from SSIS execute SQL Task

    - by Bokhari
    I am using SQL Server 2005 Business Intelligence Studio and struggling with returning an integer value from a very simple execute SQL Task. For a very simple test, I wrote the SQL Statement as: Select 35 As 'TotalRecords' Then, I specified ResultSet as ResultName = TotalRecords and VariableName = User::TotalRecords When I execute this, the statement is executed but the variable doesn't have the updated value. However, it has the default value that I specified while variable definition. The return of a date variable works, but integer variable isn't working. The type of User::TotalRecords specified is Int32 in a package scope. Thanks for any hints

  • why it is up to the compiler to decide what value to assign when assigning an out-of-range value to

    - by Allopen
    in C++ Primer 4th edition 2.1.1, it says "when assigning an out-of-range value to a signed type, it is up to the compiler to decide what value to assign". I can't understand it. I mean, if you have code like "char 5 = 299", certainly the compiler will generate asm code like "mov BYTE PTR _sc$[ebp], 43"(VC) or "movb $43, -2(%ebp)"(gcc+mingw), it IS decided by the compiler. but what if we assign a value that is given by the user input? like, via command line? and the asm code generated will be "movb %al, -1(%ebp)"(gcc+mingw) and " mov cl, BYTE PTR _i$[ebp] mov BYTE PTR _sc$[ebp], cl "(VC), so now how can compiler decide what will happen? I think now it is decided by the CPU. Can you give me a clear explanation?

  • is counter has certain value inside a class in python

    - by mazlor
    i am learning classes in python and when i was reading the documentation i found this example that i didn't understand : class MyClass: """A simple example class""" def __init__(self): self.data = [] i = 12345 def f(self): return 'hello world' then if we assign : x = MyClass() x.counter = 1 now if we implement while loop : while x.counter < 10: x.counter = x.counter * 2 so the value of x.counter will be : 16 while for example if we have a variable y : y = 1 while y < 1 : y = y *2 then if we look for the value of y we find it 1 so i don't know how is the value of counter became 16 . thanks

  • MACRO Question: Returning pointer to a certain value

    - by Andrei Ciobanu
    Is it possible to write a MACRO that has a type and a value as its input parameters (MACRO(type,value)), and returns a valid pointer to a location that holds the submitted value. This macro should perform like the following function, but in a more generic manner: int *val_to_ptr(int val){ int *r = NULL; r = nm_malloc(sizeof(*r)); *r = val; return r; } Where nm_malloc() is a failsafe malloc. The Macro usage should be compatible with this usage: printf("%d",*MACRO(int,5)); Is it possible to achieve that ?

  • jQuery pagination go to page on input value change

    - by JV10
    I'm creating some pagination for my website, and want to use an input-element to navigate between pages. Like the following example: The input would require the "return" key to be hit for the script to trigger. If the value entered is not within range and alert would trigger. e.g. If there was 32 pages, "Please enter a value between 1 and 32" Can this be done using jQuery or javascript, by detecting the value change within the range of pages and redirecting to that page? I'm trying to create the same device on Getty Images: http://www.gettyimages.com.au/Search/Search.aspx?contractUrl=2&language=en-US&family=creative&p=ball&assetType=image&clarification=ball%3A60847

  • MySQL Limiting a query to one consistent value

    - by Lucas Matos
    My current query returns a table like: +------------+ value1 | .... value1 | .... value2 | .... value3 | .... +------------+ I want: +------------+ value1 | .... value1 | .... +------------+ I want to only receive all rows with the first value. Normally I would do a WHERE clause if I knew that value, and I cannot use a LIMIT because each value has a different number of rows. Right now My query looks like "SELECT u.*, n.something, w.* FROM ... AS u, ... AS n, ... AS w WHERE u.id = n.id AND w.val = n.val AND u.desc LIKE '%GET REQUEST VARIABLE%';" This works great, except I get way too many rows and using PHP to do this ruins code portability and is superfluous. Thanks for reading

  • Domino 9 / Dojo 1.8 - Date Time Picker without default value

    - by Julian Buss
    I want a Date Time Picker control WITHOUT a default value. Doesn't seem to be possible anymore :-( To reproduce, create a blank XPage and place a Date Time Picker control. Open the XPage in the browser and you will see that it defaults to today. I didn't found any way to set the default to an empty value. I tried setting all properties/data/default to 0, null, empty string and so on - no luck. I tried the data-dojo-probs attribute with value:'', this sets the default to 1970-1-1, but not to blank. Any ideas?

  • C#: Get key and value types of non-generic IDictionary at runtime

    - by Yang Zou
    there. I am wondering how I can get the key and value types of a non-generic IDictionary at runtime. For generic IDictionary, we can use reflection to get the generic arguments, which has been answered here. But for non-generic IDictionary, for instance, HybridDictionary, how can I get the key and value types? Thanks. Edit: I may not describe my problem properly. For non-generic IDictionary, if I have HyBridDictionary, which is declared as HyBridDictionary dict = new HyBridDictionary(); dict.Add("foo" , 1); dict.Add("bar", 2); How can I find out the type of the key is string and type of the value is int? Did I make the question clear? Thanks.

    Hello everyone, I cannot change the value of an instance variable inside a function. I have defined a class: // info.h #import <Foundation/Foundation.h> @interface NSMyObject : NSObject { NSInteger i; } -(void) setI:(NSInteger)v; @end #import "info.h" @implementation NSMyObject -(void) setI:(NSInteger)v ; { i=v; } - (void)dealloc { [super dealloc]; } @end I call a function 'myFunction' with parameter temObj which is a NSMyObject instance. myFunction(temObj);//temObj is NSMyObject In the function, I can change the value of the instance variable of parameter obj. -(void)myFunction:(NSMyObject*) obj; { [obj setI:0]; } ... expecting this to change the content of temObj. But when I check the results of operation on obj in function myFunction the value of temObj.i has not changed. Welcome any comment Thanks
