  • how to detect datacard connect and disconnect event on win32

    - by Vinayaka Karjigi
    Hi All, I have a data card, as soon as i insert the data card, i am getting the events by using wm_device_change event. But I also want to get event, when my data connect actually connects to out side world. I mean to say, as soon as we click on connect/disconnect button of data card,i want to get the event. exactly speaking wanted to know, when connection is established and disconnected. data card is vodaphone data card and i am trying to browse using that data card. what ever is the SDK, somewhere the OS should get the event of connection and disconnection to network is there any way to access that event which OS is getting. as i can see in notificaiton the changes of vodaphone connection and LAN connection data card is a USB device having SIM within it, and can be used to access internet through GPRS. can i know how to do this in win32 c/c++ programe. with regards Vinayaka Karjigi

  • Where is the root [closed]

    - by smwikipedia
    I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My question is: Where is this "big tree" located?

  • ActionScript Custom Class With Return Type?

    - by TheDarkIn1978
    i just know this is a dumb question, so excuse me in advance. i want to essentially classify a simple function in it's own .as file. the function compares integers. but i don't know how to call the class and receive a boolean return. here's my class package { public class CompareInts { public function CompareInts(small:int, big:int) { compare(small, big); } private function compare(small:int, big:int):Boolean { if (small < big) return true; else return false; } } } so now i'd like to write something like this: if (CompareInts(1, 5) == true). or output 'true' by writing trace(CompareInts(1, 5));

  • Unsure how i load the right data into a tableview, chosen from a previous tableview.

    - by Bob
    I currently have two TableViewControllers. The first has seven objects, each day-name listed. Weekdays *mandag = [[Weekdays alloc] initWithName:@"Mandag" daylist:mondayArray]; Weekdays *tirsdag = [[Weekdays alloc] initWithName:@"Tirsdag" daylist:tuesdayArray]; Weekdays *onsdag = [[Weekdays alloc] initWithName:@"Onsdag" daylist:wedensdayArray]; Weekdays *torsdag = [[Weekdays alloc] initWithName:@"Torsdag" daylist:thursdayArray]; Weekdays *fredag = [[Weekdays alloc] initWithName:@"Fredag" daylist:fridayArray]; Weekdays *lordag = [[Weekdays alloc] initWithName:@"Lørdag" daylist:saturdayArray]; Weekdays *sondag = [[Weekdays alloc] initWithName:@"Søndag" daylist:sundayArray]; daylist being a NSMutableArray. The idea is: The name of the day is displayed on table-1. And the array (daylist) of each day is displayed on table-2 - when tabbed one a day. The first table, displaying the names is working fine: VisueltSkemaAppDelegate *appDelegate = (VisueltSkemaAppDelegate *)[[UIApplication sharedApplication] delegate]; Weekdays *ugeDag = (Weekdays *)[appDelegate.ugeDage objectAtIndex:indexPath.row]; cell.textLabel.text = ugeDag.name; return cell; However i thought i could do the same, for the second table - but i have been strugling with it for hours now. This is what i got: VisueltSkemaAppDelegate *appDelegate = (VisueltSkemaAppDelegate *)[[UIApplication sharedApplication] delegate]; Weekdays *ugeDag = (Weekdays *)[appDelegate.ugeDage objectAtIndex:indexPath.row]; cell.textLabel.text = [ugeDag.daylist objectAtIndex:indexPath.row]; return cell; Abit more of the code: http://pastebin.com/iW5AAJXt

  • If you use XML Serialization how do you validate data?

    - by chobo2
    Hi I am planning to try to use XML Serialization in C# but I am wondering if I get a .xml file how do I check if the xml file confirms to the right type? Like usually you would make a schema that you can validate against to make sure if it confirms to the right format. Can you hook a schema up to to XML Serialization or does it do this checking automatically? Thanks

  • What data (if any) persists across web-requests in Ruby on Rails?

    - by Daniel Beardsley
    I decided to use the singleton design pattern while creating a view helper class. This got me thinking; will the singleton instance survive across requests? This led to another question, Which variables (if any) survive across web requests and does that change depending on deployment? (Fastcgi, Mongrel, Passenger, ...) I know that Controller instance variables aren't persisted. I know Constants are persisted (or reloaded?). But I don't know about class variables, instance variables on a class, Eigenclasses, ...

  • Array as struct database?

    - by user2985179
    I have a struct that reads data from the user: typedef struct { int seconds; } Time; typedef struct { Time time; double distance; } Training; Training input; scanf("%d %lf", input.time.seconds, input.distance); This scanf will be looped and the user can input different data every time, I want to store this data in an array for later use. I THINK I want something like arr[0].seconds and arr[0].distance. I tried to store the entered data in an array but it didn't really work at all... Training data[10]; data[10].seconds = input.time.seconds; data[10].distance = input.distance; The data will wipe when the program closes and that's how I like it to be. So I want it to be stored in an array, no files or databases!

  • Using Jquery 1.8.0 return false is not breaking an each() loop

    - by user1879729
    Here is the script I am using. $('.row').each(function(){ $(this).each(function(){ if($(this).find('.name').val()==""){ $(this).find('.name').val(data.name); $(this).find('.autonomy').val(data.autonomy); $(this).find('.purpose').val(data.purpose); $(this).find('.flow').val(data.flow); $(this).find('.relatedness').val(data.relatedness); $(this).find('.challenge').val(data.challenge); $(this).find('.mastery').val(data.mastery); $(this).find('.colour').val(data.colour); done=true; } if(done==true){ alert("here"); return false; } }); }); It just seems to totally ignore the return false and I can't seem to work out why!

  • How can I get class, property, and method data from files without executing their code, similar to R

    - by Chris
    I have a bunch of PHP files with classes, in them (although I can't be 100% sure that they won't have code outside of classes in them too), and I need to parse these files to get information about the classes, such as the names of the classes, the methods, the properties, whether they are private/public/static, etc. I looked at PHP's reflection classes and this is very close to what I want but the reflection doesn't seem to use external files and it appears to need to define the classes first. I need to make sure that none of the code is executed and I will be editing the files so I can't guarantee that they will even be error-free. Any suggestions? Thanks.

  • Extracting data from a text file to use in a python script?

    - by Rob
    Basically, I have a file like this: Url/Host: www.example.com Login: user Password: password How can I use RegEx to separate the details to place them into variables? Sorry if this is a terrible question, I can just never grasp RegEx. So another question would be, can you provide the RegEx, but kind of explain what each part of it is for?

  • Storing large json strings to database + hash

    - by Guy
    I need to store quiete large JSON data strings to the database. I am using gzip to compress the string and therefore BLOB MySQL data type to store it. However, only 5% of all the requests contain unique data and only unique data ought to be stored to the database. My approach is as follows. array_multisort data (array [a, b, c] is virtually the same as [a, c, b]). json_encode data (json_encode is faster than serialize; we need string array representation for the step 3). sha1 data (slower than md5, though less possible the collisions). Check if the hash exists in the database. 5.1 yes – do not insert the data. 5.2. no – gzip the data and store it along the hash. Is there anything about this (apart from storing JSON data to the database in the first place) that sounds fishy or should be done a different way? p.s. We are talking about a database with roughly 1kk unique records being created every month.

  • How to send data many times to web browser in response to one request?

    - by robert_d
    I have a form on my web page, it allows to submit many queries to my website, every query is on a separate line in TextArea. Because waiting for all queries to complete is too long I would like to update the web page after every query completes - send result of one query to a web browser, new result should be appended to old results that are already on the web page. How to do this in ASP.NET MVC 2? I will be grateful for helpful responses.

  • How to make cakePHP retreive the data represented by a foreign key?

    - by XL
    Greetings cake experts, I have a question that I think would really help a lot of people getting started with cakePHP. I have a feeling it will be easy for some of you, but it is quite challenging to me. I have a simple database with multiple tables. I can't figure out how to make cakePHP display the values associated with a foreign key in an index view. Or create a view where the fields of my choice (the ones that make sense to users like location name - not location_id can be updated or viewed on a single page). I have created an example at http://lovecats.cakeapp.com that illustrate the question. If you look at the page and click the "list cats", you will notice that it shows the location_id field from the locations table. You will also notice that when you click "add cats", you must choose a location_id from the locations table. This is the automagic way that cakePHP builds the app. I want this to be the field location_name. The database is setup so that the table cats has a foreign key called location_id that has a relationship to a table called locations. This is my problem: I want these pages to display the location_name instead of the location_id. If you want to login to the application, you can go to http://cakeapp.com/sqldesigners/sql/lovecats and the password 'password' to look at the db relationships, etc. How do I have a page that shows the fields that I want? And is it possible to create a page that updates fields from all of the tables at once? This is the slice of cake that I have been trying to figure out and this would REALLY get me over a hump. You can download the app and sql from the above url.
