  • Question About NerdDinner Controller Constructors

    - by Gavin Draper
    I've been looking at the Nerd Dinner app, more specifically how it handles its unit tests. The following constructors for the RSVPController are confusing my slightly public RSVPController() : this(new DinnerRepository()) { } public RSVPController(IDinnerRepository repository) { dinnerRepository = repository; } From what I can tell the second one is used by the unit tests so it can use Fake repositories. What I cant work out is what the first constructor does. It doesn't seem to ever set the dinnerRepository variable, it seems to imply its inheriting from something but I really don't get it. Can anyone explain? Thanks

  • Question about fwrite API

    - by michael
    Hi, In C++, there is a fwrite() which writes a buffer to a file on disk: http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/ Can you please tell me if there is any buffer inside that fwrite implementation? i.e. if I call fwrite() multiple times (say 10 times), does it actually invoke file i/o 10 different times? Thank you.

  • 2 Minute question - HTML / CSS If div within div expands expand parent div

    - by Ozaki
    I have a setup lets say like follows: <div id="nav"> <div id="innernav"> //With dynamic content here. </div> </div> I am running a script that sizes #nav to the size of the browser window in height. But sometimes my dynamic content is now getting bigger than the height of the window.. Is there a way I can enforce that when #innernav exceeds #nav that #nav will increase in size?

  • 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 ?

  • Basic visual studio intellisense question

    - by maxp
    Ive used visual studio for years, but the answer this eludes me: When intellisense pops up, for a method call that takes more than one parameter, the summary for the first parameter is shown. The only way i've found to show the summary for the following parameter(s) is to either supply each parameter or just hit comma until i get the one im looking for. Ive tried ctrl+right arrow, shift + right arrow etc etc, without success. Just curious is all.

  • php mail send form question?

    - by eberswine
    Wondering if anyone know how to automatically send the user an email after he/she fills out a form. I have the form emailed to me after it gets submitted, but I can't figure out how to capture the user's email from the form field and have it send it to them automatically??? Here is some code that I use to send the mail: //mail the message before redirecting if($_POST['dosend'] == "yes"){ // The message $headers = "From: [email protected]"; $message = "NEW Message :: ".$_POST['event_name']." \n Email: ".$_POST['email']." \n Click link to http://www.domain.com/admin/ Approve this Event!"; // Send mail('[email protected]', 'New :: Calendar Message', $message, $headers); } //end mail

  • A brief question about JS or AJAX

    - by Luke
    I have been finding ways around this for a long time but think it's time I addressed it. If I have a page that has a dropdown menu, is there anyway I can select a value which will subsequently load other values further down. Can this be done without a page reload? I will give you an example. Say I was making some tools for an admin panel, but first of all they needed to select a member to work with. They would select the member and then below, the fields about that member would be populated based on what was selected in the first menu. As I have already asked, can this be done without a page reload? Thanks for reading.

  • Oh no, Not another Undefined Reference Question!

    - by roony
    Unfortunately yes. I have my shared library compiled, the linker doesn't complain about not finding it but still I get undefined reference error. Thinking that I might be doing something wrong I did a little research and found this nice, simple walkthrough: http://www.adp-gmbh.ch/cpp/gcc/create_lib.html which I've followed to the letter but still I get: $ gcc -Wall main.c -o dynamically_linked -L.\ -lmean /tmp/ccZjkkkl.o: In function `main': main.c:(.text+0x42): undefined reference to `mean' collect2: ld returned 1 exit status This is pretty simple stuff so what's going wrong?!?!? Can anyone suggest something in my set up that might need checking/tweeking? GCC 4.3.2 Fedora 10 64-bit

  • JSF templating beginner's question.

    - by Nitesh Panchal
    Hello, I belong to Asp.Net but just starting to learn JSF. I wanted to know whether all features of MasterPage are available in JSF templating? I mean say suppose i have a menu in template, and based on roles menu changes. If the Admin logs in, he will get to show more options and if general user logs in he will get to see less options. Now i have a managed bean for my "real" page(not template). How do i use this managed bean to toggle my control in template on and Off?

  • SVN Version Rollback Question

    - by phimuemue
    Hello, I'm using SVN (TortoiseSVN) and often came into the following situation: I wanted to discard any changes since a specific (old) revision and turn all files back to this specific (old) version. Then I wanted to work further as if this specific (old) revision was the newest one, i.e. I wanted to be able to commit the specific old revision as a new revision. I found several solutions for this problem (for example stackoverflow.com/questions/402159/roll-back-or-revert-entire-svn-repository-to-an-older-revision or rustyrazorblade.com/2007/04/how-to-roll-back-commits-to-an-earlier-version-of-a-repository-in-svn/). However, I wonder if there is a simple way to roll back to a specific revision. I thought version control is just good for such things (or am I misunderstanding something?). Is there a simple command/button/etc. that takes an updates my local repository to an old revision and declares it to be the newest one? Since I suppose that there is no "built-in" function to do this, I wanted to know what reason lead the developers to the decision not to integrate this feature. Does anybody know this?
