  • Setting Response.StatusCode in View in ASP.NET MVC2

    - by Guy
    I've just converted a project from MVC1 to MVC2. In the MVC1 project the HTTP status code was being set in some of the views. These views are now generating this exception: Server cannot set status after HTTP headers have been sent. What has changed from MVC1 to MVC2 to cause this and is there any way to fix this?

  • How to properly downcast in C# with a SWIG generated interface?

    - by JG
    I've got a very large and mature C++ code base that I'm trying to use SWIG on to generate a C# interface for. I cannot change the actual C++ code itself but we can use whatever SWIG offers in the way of extending/updating it. I'm facing an issue where a function C++ is written as such: A* SomeClass::next(A*) The caller might do something like: A* acurr = 0; while( (acurr = sc->next(acurr)) != 0 ){ if( acurr isoftype B ){ B* b = (B*)a; ...do some stuff with b.. } elseif( acurr isoftype C ) ... } Essentially, iterating through a container elements that depending on their true type, do something different. The SWIG generated C# layer for the "next" function unfortunately does the following: return new A(); So the calling code in C# land cannot determine if the returned object is actually a derived class or not, it actually appears to always be the base class (which does make sense). I've come across several solutions: Use the %extend SWIG keyword to add a method on an object and ultimately call dynamic_cast. The downside to this approach, as I see it, is that this requires you to know the inheritance hierarchy. In my case it is rather huge and I see this is as a maintenance issue. Use the %factory keyword to supply the method and the derived types and have SWIG automatically generate the dynamic_cast code. This appears to be a better solution that the first, however upon a deeper look it still requires you to hunt down all the methods and all the possible derived types it could return. Again, a huge maintenance issue. I wish I had a doc link for this but I can't find one. I found out about this functionality by looking through the example code that comes with SWIG. Create a C# method to create an instance of the derived object and transfer the cPtr to the new instance. While I consider this clumsy, it does work. See an example below. public static object castTo(object fromObj, Type toType) { object retval = null; BaseClass fromObj2 = fromObj as BaseClass; HandleRef hr = BaseClass.getCPtr(fromObj2); IntPtr cPtr = hr.Handle; object toObj = Activator.CreateInstance(toType, cPtr, false); // make sure it actually is what we think it is if (fromObj.GetType().IsInstanceOfType(toObj)) { return toObj; } return retval; } Are these really the options? And if I'm not willing to dig through all the existing functions and class derivations, then I'm left with #3? Any help would be appreciated.

  • Installing assemblies to GAC with Windows Installer

    - by Andy Xufuris
    I am creating a Windwos Installer project just for the use of installing our third party assemblies into the gac of the users computer. The problem i am running into, is when i make an update to the assemblie and increment it's version number, i get an error saying: "Another version of this product is already installed. Installation of this version cannot continue..." I would have figured that windows installer would update the local machine with the new assemblie. Am i doing something wrong?

  • Checking to see if a number is evenly divisible by other numbers with recursion in Python

    - by Ernesto
    At the risk of receiving negative votes, I will preface this by saying this is a midterm problem for a programming class. However, I have already submitted the code and passed the question. I changed the name of the function(s) so that someone can't immediately do a search and find the correct code, as that is not my purpose. I am actually trying to figure out what is actually MORE CORRECT from two pieces that I wrote. The problem tells us that a certain fast food place sells bite-sized pieces of chicken in packs of 6, 9, and 20. It wants us to create a function that will tell if a given number of bite-sized piece of chicken can be obtained by buying different packs. For example, 15 can be bought, because 6 + 9 is 15, but 16 cannot be bought, because no combination of the packs will equal 15. The code I submitted and was "correct" on, was: def isDivisible(n): """ n is an int Returns True if some integer combination of 6, 9 and 20 equals n Otherwise returns False. """ a, b, c = 20, 9, 6 if n == 0: return True elif n < 0: return False elif isDivisible(n - a) or isDivisible(n - b) or isDivisible(n - c): return True else: return False However, I got to thinking, if the initial number is 0, it will return True. Would an initial number of 0 be considered "buying that amount using 6, 9, and/or 20"? I cannot view the test cases the grader used, so I don't know if the grader checked 0 as a test case and decided that True was an acceptable answer or not. I also can't just enter the new code, because it is a midterm. I decided to create a second piece of code that would handle an initial case of 0, and assuming 0 is actually False: def isDivisible(n): """ n is an int Returns True if some integer combination of 6, 9 and 20 equals n Otherwise returns False. """ a, b, c = 20, 9, 6 if n == 0: return False else: def helperDivisible(n): if n == 0: return True elif n < 0: return False elif helperDivisible(n - a) or helperDivisible(n - b) or helperDivisible(n - c): return True else: return False return helperDivisible(n) As you can see, my second function had to use a "helper" function in order to work. My overall question, though, is which function do you think would provide the correct answer, if the grader had tested for 0 as an initial input?

  • Visual Studio Formatting -- Change Method Color

    - by Daniel
    The default appearance of a method for example, ".ToString()" is by default the color black. I want to make it a different color to stand out but I do not see any options that reference this option specifically. I remember one of former collegues showing me his VS IDE years ago and he had it setup this way but I cannot recall what he did. Does anyone have any ideas on how to do this?

  • jsTree and SVG Editor conflict in active selected items?

    - by marknt15
    Hi, I'm using jsTree and SVG-Edit in the same file but there is a conflict in the active selected item. For example I clicked a tree item then I cannot draw in the svgcanvas div anymore. Maybe because of you click the item in jsTree then it's always selected and the svgcanvad div will not be active anymore? Any help, tips or tutorials will help. Thanks, Mark

  • Does mercurial-server support subrepo?

    - by Esteban Feldman
    I installed mercurial-server on one of my machines, cloned my project there, it has 3 subrepos, and when I try to clone it back to another location I get an error: remote: mercurial-server: Cannot create repo under existing repo abort: no suitable response from remote hg! So I'm starting to think that mercurial-server doesn't handle subrepo. Any clue?

    Hi, One of my friends got the access database with Forms (VBA) and wish to migrate all the database table to the newly installed MOSS 2007 site. He is using SSMI for this purpose. He cannot do it because there are plenty of errors and warnings. I think it is due to the old Access queries. Is there any other way to import the database to sql 2005 from access ? Thanks

  • Strange Values in SYS.DM_TRAN_LOCKS table RESOURCE_ASSOCIATED_ENTITY_ID column

    - by AJM
    I’ve been trying to understand some strange values in the RESOURCE_ASSOCIATED_ENTITY_ID column of SYS.DM_TRAN_LOCKS when RESOURCE_TYPE is “OBJECT”. Although these should be object Ids, I cannot determine what object they actually refer to. I’ve tried everything I can think of, including querying all system tables with columns of type INT and BIGINT to see if I can find the value. No luck. The funny values actually appear in SYS.DM_TRAN_LOCKS, SYS.SYSLOCKINFO and SP_LOCK.
