20,033 | 20,034 | extend SplFileObject with fread method | <p>PHP5 introduced an object-oriented file wrapper, <strong>SplFileObject</strong>. I guess I just found out why hardly anybody is using it. It's purely line-oriented, there is no fread() method - which the corresponding frwite seemed to suggest.</p>
<p>So now I'm wondering if I can extend it. I'm however not sure what's the better workaround. SplFileObject is not particular helpful in tucking the file pointer ($fp) away - it's either a private attribute or ZE-internal resource. So how would I extend it to get a fread method?</p>
<ul>
<li>Implement fread() as string collecting <strong>loop with fgets()</strong>, with eventual seeking if only a specific size was requested and fgets read too far until the next \n line break.</li>
<li>Use a custom constructor, which opens the file a second time and stores a <strong>secondary file pointer</strong>, in case I want to call fread() instead of the parent class methods.</li>
</ul>
<p>I'd go for the fgets workaround loop, but it sounds cumbersome and slow and provides for more potential pitfalls. OTOH opening a secondary file pointer seems not a good approach either and needs a custom destructor too.</p>

<p>I have 2 questions that are very similar..</p>
<p>In my program a used typedef on the container and made objects of the container like so:</p>
<pre><code>typedef set<Item*> ItemSet;
ItemSet allBooks; // holds all the information
ItemSet allCDS;
ItemSet allDVDs;
</code></pre>
<p>First question is there is no typdef in C# i think its equivalent is using? But i cant use it on a container. Is there a way to do something similar above in C# or should i just create multiple sets?
I decided that Hashset is similar to set in C++</p>
<pre><code>HashSet<Item> keys = new HashSet<Item>();
</code></pre>
<p>Second question is i also used typedef on a set outside the class and then in the private section
i made and object of the set. Can i do this in C#?</p>
<pre><code>typedef set<string> StringSet;
class Item
{
private:
string Title;

1,636,722 | 1,636,723 | text editor for android - how to hook into other applications | <p>Can you please point me into the right direction please.</p>
<p>Basically I would like to code up a text editor application to suite my personal needs (would like it to specially handle some keyboard combination - as shift + x, etc).</p>
<p>The first question - is to how to implement the text editor itself - I know there is a class TextView and I would need to handle OnPress methods (or something like this)
to override inputs (e.g. if the user pressed shift + X - I would like "XXXX" to append to the input). Is TextView where should I start or where a better (at the same time
simple for a novice in the android programming) to start?</p>
<p>My second question is, once I implemented such application - how can I hook/integrate it to/with other applications - such as sms/email applications, etc.</p>
<p>If you can point me to some article/source code on the web - would really appreciate this, because it is quite important to me, it really is.</p>

301,502 | 301,503 | Designing an asynchronous task library for ASP.NET | <p>The ASP.NET runtime is meant for short work loads that can be run in parallel. I need to be able to schedule periodic events and background tasks that may or may not run for much longer periods.</p>
<p>Given the above I have the following problems to deal with:</p>
<ul>
<li>The AppDomain can shutdown due to changes (Web.config, bin, App_Code, etc.)</li>
<li>IIS recycles the AppPool on a regular basis (daily)</li>
<li>IIS itself might restart, or for that matter the server might crash</li>
</ul>
<p>I'm not convinced that running this code inside ASP.NET is not the right thing to do, becuase it would allow for a simpler programming model. But doing so would require that an external service periodically makes requests to the app so that the application is keept running and that all background tasks are programmed with utter most care. They will have to be able to pause and resume thier work, in the event of an unexpected error.</p>
<p>My current line of thinking goes something like this:</p>
<p>If all jobs are registered in the database, it should be possible to use the database as a bookkeeping mechanism. In the case of an error, the database would contain all state necessary to resume the operation at the next opportunity given.</p>
<p>I'd really appriecate some feedback/advice, on this matter. I've been considering running a windows service and using some RPC solution as well, but it doesn't have the same appeal to me. And I'd instead have a lot of deployment issues and sycnhronizing tasks and code cross several applications. Due to my business needs this is less than optimial.</p>

Are there some good video tutorials which I can buy on CD/DVD? Could You recommend some books?</p>

597,462 | 597,463 | Forms with a variable number of fields | <p>I'm attempting to create a sort of marketplace. Each item on the market has a type (i.e. the item being sold), a value, a quantity, a seller name, and an id, and all of this information is stored in a MySQL database.</p>
<p>When the user views the market, all entries in the market are returned. In addition, an input text field appears at the end of each entry. The user can enter any number between leaving it blank (0) and the max quantity available.</p>
<p>My problem is that since each input field is the result of a while loop of unknown iterations, I can't simply hard code a name into each field. I've tried using a counter variable to keep track and make names, but it doesn't seem to be working. For example: <code>name='.$i++.'</code></p>
<p>On a related note, in order for the program to work, each field needs to send two values - the id (which I can use to look up the rest of the entry's values) and the quantity that the user wishes to purchase. I've been doing this with a hidden field before the input quantity field. I'm not sure if this is a good way of going about this, but I should note that there's no need as far as I can tell for the id to be kept secret.</p>
<p>Just so everything's clear, here's a basic UI mockup:
<a href="http://img850.imageshack.us/img850/2654/marketui.jpg" rel="nofollow">http://img850.imageshack.us/img850/2654/marketui.jpg</a></p>
<p>Note that the column starting with consists of user inputted values (i.e. the 100s are the values of user-inputted text fields). The hitch is that while there are 2 rows in this example, the actual number is not deterministic, and so I can't hard code names for each input field.</p>
