  • Mocking a Wcf ServiceContract

    - by Michael
    I want to mock a ServiceContract. The problem is that Moq (and Castle Dynamic-Proxy) copies the attributes from the interface to the dynamic proxy which Wcf don't like. Wcf sais: The ServiceContractAttribute should only be define on either the interface or the implementation, not both.

  • missing ';' before namespace when using boost 1.4.2

    - by Adam Haile
    Working on moving some C++ code from Linux over to Windows. The code uses boost 1.4.2, however it keeps failing out on building the boost modules. Basically, every boost hpp file that happens to contain "namespace boost" errors with: error C2143: syntax error : missing ';' before 'namespace' Any idea what could be causing this?

  • How do I call setattr() on the current module?

    - by Matt Joiner
    What do I pass as the first parameter "object" to the function setattr(object, name, value), to set variables on the current module? For example: setattr(object, "SOME_CONSTANT", 42); giving the same effect as: SOME_CONSTANT = 42 within the module containing these lines (with the correct object). I'm generate several values at the module level dynamically, and as I can't define __getattr__ at the module level, this is my fallback.

  • Future proof Tweeting with PHP

    - by YsoL8
    Hello I'm looking to implement a system for tweeting directly from my site backend, which is written in PHP 5. I have a script from the internet that I can adapt, but I'm concerned that when Twitter switches to Oauth only, I'll be out in the cold. Basically, I'm hoping someone can point me toward a script/tutorial that will let me do the following: access twitter via the Oauth system Post Tweets and receive error codes Let me define an application/site name (I'm a bit fuzzy on whether Twitter allows this) Ideally I need all 3 points explained in detail. Thanks

This is somewhat annoying. Is there any way to disable this?

    I'm working on some C code filled with macros like this: #define SAFE_FREE(x) do { if ((x) != NULL) {free(x); x=NULL;} } while(0) Can anyone explain what this macro does, and why do {} while(0) is needed? Wouldn't that just execute the code once?

  • Active User Tracking, PHP Sessions

    - by Nik
    Alright, I'm trying to work on a function for active user counting in an AJAX based application. I want to express the below SQL Query in correct syntax but I'm not sure how to write it. The desired SQL Query is below: SELECT count(*) FROM active WHERE timestamp > time() - 1800 AND nick=(a string that doesn't contain [AFK]) Now, I do understand that time() - 1800 can be assigned to a variable, but how is timestamp > variable and nick that doesn't contain a string written in SQL?

  • Passing array into constructor to use on JList

    - by OVERTONE
    I know the title sound confusing and thats because it is. its a bit long so try too stay with me. this is the layout i have my code designed variables constructor methods. im trying too fill a Jlist full on names. i want too get those names using a method. so here goes. in my variables i have my JList. its called contactNames; i also have an array which stores 5 strings which are the contacts names; heres the code for that anyway String contact1; String contact2; String contact3; String contact4; String contact5; String[] contactListNames; JList contactList; simple enough. then in my constructor i have the Jlist defined to fill itself with the contents of the array fillContactList(); JList contactList = new JList(contactListNames); that method fillContactList() is coming up shortly. notice i dont have the array defined in the constructor. so heres my first question. can i do that? define the array to contain something in te constructor rather than filling it fromt the array. now heres where stuff gets balls up. ive created three different methods all of which havent worked. basically im trying to fill the array with all of them. this is the simplest one. it doesnt set the Jlist, it doesnt do anything compilicated. all it trys too do is fill the array one bit at a time public void fillContactList() { for(int i = 0;i<3;i++) { try { String contact; System.out.println(" please fill the list at index "+ i); Scanner in = new Scanner(System.in); contact = in.next(); contactListNames[i] = contact; in.nextLine(); } catch(Exception e) { e.printStackTrace(); } } } unfortunately this doesnt qwork. i get the print out to fill it at index 0; i input something and i get a nice big stack trace starting at contactListNames[i] = contact; so my two questions in short are how i define an array in a constructor. and why cant i fill the array from that method. ************************888 **************************888 stack trace by request please fill the list at index 0 overtone java.lang.NullPointerException please fill the list at index 1 at project.AdminMessages.fillContactList(AdminMessages.java:408) at project.AdminMessages.<init>(AdminMessages.java:88) at project.AdminUser.createAdminMessages(AdminUser.java:32) at project.AdminUser.<init>(AdminUser.java:18) at project.AdminUser.main(AdminUser.java:47) it was a null poiinter exception

  • IgnoreArguments including an Action<T>

    - by James L
    I'm probably missing something obvious here, so apologies in advance! Using Rhino Mocks, how do I set an expectation that a method taking an Action will be called, but I want to use IgnoreArguments. Obviously I can't specify null as that isn't an Action, and I dont want any meaningless code in the test. As I said, it's probably obvious by the syntax is eluding me at the moment!

  • using an array in a custom formula in crystal reports xi

    - by Kim Sharpe
    I have a formula which is working; the formula uses an array. I tried to extract the formula to create a custom formula but now get an error in the syntax. I am wondering if the array is causing the problem as the error is on the line: last_element_current:=val(sc_array[1]) + 1; and the error is: the ) is missing and highlights the variable sc_array before the index [1].
