  • Most Frequent Number

    - by VBeginner
    Hello, I've used an array of strings to populate a DataGridView. How do I go about finding the most frequently occurring number? Or, even better, order them by most frequently occuring? Thank You.

  • VS 2008 debugger: How does it decide what Cassini port to run a web service under?

    - by BDW
    I have a VS 2008 solution that includes a web site and a web service. I'm developing both at once, and it's helpful to be able to debug from one into the other. It occasionally can't find the web service. If I look in the web.config, I find the port number it's looking at is not the port number it auto-runs the service in when I use the debugger. For example, the web.config reference says something like: add key="mynamespace.mywebservice" value="http://localhost:55765/mywebservice.asmx" When I hover over the Cassini port icon, I find that the web service is running in port 55382 (or some other non-55765 port). No wonder it can't find it. Is there a way to enforce that the port number it runs under is the one specified in the web config? And if it's not using the web config port number to figure out where to run it... where does it decide? I know in VS2005, there was a way to specify the port number to use when debugging, but I can't find that anywhere in the web service project in VS 2008. This is really going to cause problems as more developers come on to this project - how can I fix it? Deleting and re-adding the web services to the project fixes it, but I'd literally have to do it a couple times a day, not an ideal solution.

  • List iterator not dereferencable?

    - by Roderick
    Hi All I get the error "list iterator not dereferencable" when using the following code: bool done = false; while (!_list_of_messages.empty() && !done) { // request the next message to create a frame // DEBUG ERROR WHEN NEXT LINE IS EXECUTED: Counted_message_reader reader = *(_list_of_messages.begin()); if (reader.has_more_data()) { _list_of_frames.push_back(new Dlp_data_frame(reader, _send_compressed_frames)); done = true; } else { _list_of_messages.pop_front(); } } (The line beginning with "Counted_message_reader..." is the one giving the problem) Note that the error doesn't always occur but seemingly at random times (usually when there's lots of buffered data). _list_of_messages is declared as follows: std::list<Counted_message_reader> _list_of_messages; In the surrounding code we could do pop_front, push_front and size, empty or end checks on _list_of_messages but no erase calls. I've studied the STL documentation and can't see any glaring problems. Is there something wrong with the above code or do I have a memory leak somewhere? Thanks! Appreciated!

  • How to load a type in parent-child website

    - by salvationishere
    I am developing a C# VS 2008 / SQL Server 2008 website. Although this same code compiles in the Project version, the website version does not compile. Many of their files are the same so I do not understand even where to look. The only compile error I get is: Could not load type 'DataMatch' in my DataMatch.aspx file. Is the problem in my web.config file? How do websites differ from projects in VS? All four of these files reside in same directory. Default.aspx file: <%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="AddFileToSQL" Title="Untitled Page" % ...

  • Using MATLAB's plotting features as an interactive part of a Fortran program

    - by ldigas
    Although many of you will have a decent idea of what I'm aiming at, just from reading the title -- allow me a simple introduction still. I have a Fortran program - it consists of a program, some internal subroutines, 7 modules with its own procedures, and ... uhmm, that's it. Without going into much detail, for I don't think it's necessary at this point, what would be the easiest way to use MATLAB's plotting features (mainly plot(x,y) with some customizations) as an interactive part of my program ? For now I'm using some of my own custom plotting routines (based on HPGL and Calcomp's routines), but just as part of an exercise on my part, I'd like to see where this could go and how would it work (is it even possible what I'm suggesting?). Also, how much effort would it take on my part ? I know this subject has been rather extensively described in many "tutorials" on the net, but for some reason I have trouble finding the really simple yet illustrative introductory ones. So if anyone can post an example or two, simple ones, I'd be really grateful. Or just take me by the hand and guide me through one working example. platform: IVF 11.something :) on Win XP SP2, Matlab 2008b

  • How to program three editions Light, Pro, Ultimate in one solution

    - by Henry99
    I'd like to know how best to program three different editions of my C# ASP.NET 3.5 application in VS2008 Professional (which includes a web deployment project). I have a Light, Pro and Ultimate edition (or version) of my application. At the moment I've put all in one solution with three build versions in configuration manager and I use preprocessor directives all over the code (there are around 20 such constructs in some ten thousand lines of code, so it's overseeable): #if light //light code #endif #if pro //pro code #endif //etc... I've read in stackoverflow for hours and thought to encounter how e.g. Microsoft does this with its different Windows editions, but did not find what I expected. Somewhere there is a heavy discussion about if preprocessor directives are evil. What I like with those #if-directives is: the side-by-side code of differences, so I will understand the code for the different editions after six months and the special benefit to NOT give out compiled code of other versions to the customer. OK, long explication, repeated question: What's the best way to go?

  • MVC C# Controller Method to return Tables

    - by Rob Tiu
    I'm a real beginner with MVC and my issue is this, I have a mdf database with multiple tables and I want to have a method return "ANY" table from the database and pass it to a aspx view. Examples of other tables in the database: Articles, Products, Supplies Here is an example of my code to view an Article Table from the database: //USING LINQ-SQL CONTEXT DATABASE public ActionResult ArticlePage() { tinypeas_db_contextDataContext context = HttpContext.Application["context"] as tinypeas_db_contextDataContext; try { return View(context.Articles); } catch { return Json(false, JsonRequestBehavior.AllowGet); } } How would I modify this method to dynamically pass any table to the view? Or should I be using something else other than Linq-to-SQL

  • What's the best way to share one Entity Framework 4 data model among multiple applications (meant to

    - by Ivan
    A project (a "solution" to say in VS terms) of mine consists of an ASP.Net 4 Dynamic Data Entities web application, some WinForms applications, some WPF applications, some services. All they are intended to work with one SQL Server database, generated from an Entity Framework 4 model as table-per-type, with lots of inheritance and multiple self-referencing relations. Where do I best put my model? In a separate class library, a copy in every project, in one project, etc. What naming should I best use? Is it good idea to name it MySolution.MyClassLibrary.MySolutionEntities, or just MySolutionEntities or just MySolution? Can you share any useful experience on this subject?

  • Manage DirectX as a starting point

    - by numerical25
    I know the difference between manage and unmanaged DirectX. My question is if I decided to do managed directX as a starting point, would it help me to better understand unmanaged DirectX. Honestly, the only thing I see different about the 2 is how you initiate and access resources. Matrix Math is Matrix no matter what so If I learn it in managed, then I should be fine in unmanaged

  • inline and member initializers

    - by Alexander
    When should I inline a member function and when should I use member initializers? My code is below.. I would like to modify it so I could make use some inline when appropriate and member initializers: #include "Books.h" Book::Book(){ nm = (char*)""; thck = 0; wght = 0; } Book::Book(const char *name, int thickness, int weight){ nm = strdup(name); thck = thickness; wght = weight; } Book::~Book(){ } const char* Book::name(){ return nm; } int Book::thickness(){ return thck; } int Book::weight(){ return wght; } // // Prints information about the book using this format: // "%s (%d mm, %d dg)\n" // void Book::print(){ printf("%s (%d mm, %d dg)\n", nm, thck, wght); } Bookcase::Bookcase(int id){ my_id = id; no_shelf = 0; } int Bookcase::id(){ return my_id; } Bookcase::~Bookcase(){ for (int i = 0; i < no_shelf; i++) delete my_shelf[i]; } bool Bookcase::addShelf(int width, int capacity){ if(no_shelf == 10) return false; else{ my_shelf[no_shelf] = new Shelf(width, capacity); no_shelf++; return true; } } bool Bookcase::add(Book *bp){ int index = -1; int temp_space = -1; for (int i = 0; i < no_shelf; i++){ if (bp->weight() + my_shelf[i]->curCapacity() <= my_shelf[i]->capacity()){ if (bp->thickness() + my_shelf[i]->curWidth() <= my_shelf[i]->width() && temp_space < (my_shelf[i]->width() - my_shelf[i]->curWidth())){ temp_space = (my_shelf[i]->width()- my_shelf[i]->curWidth()); index = i; } } } if (index != -1){ my_shelf[index]->add(bp); return true; }else return false; } void Bookcase::print(){ printf("Bookcase #%d\n", my_id); for (int i = 0; i < no_shelf; i++){ printf("--- Shelf (%d mm, %d dg) ---\n", my_shelf[i]->width(), my_shelf[i]->capacity()); my_shelf[i]->print(); } }

  • Repurpose builtin Word commands - access original command within repurposed function

    - by Aurril
    It is possible to repurpose a Word builtin command in Word 2007 using the customUI.xml file. Example: <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> <commands> <command idMso="Save" onAction="MySave"/> </commands> </customUI> I then have to define a callback function in VBA which is used instead of the builtin function: 'Callback for Save onAction Sub MySave(control As IRibbonControl, ByRef cancelDefault) someFancyPreparationFunction oldSaveFunction ' Where, how? someOtherFancyAfterWorkFunction End Sub And here is my problem, if I want to reuse internal functionality in my repurposed Function, I don't know how to access it. My example is trivial and the save could be easily rebuilt by a call to ThisDocument.save but as I said, it is just an example to show the problem. A call to CommandBars.ExecuteMso('Save') would call my repurposed function and not the original one. Any ideas on how to access the internal functionality after repurposing would be very appreciated!

  • Redundant assert statements in .NET unit test framework

    - by Prabhu
    Isn't it true that every assert statement can be translated to an Assert.IsTrue, since by definition, you are asserting whether something is true or false? Why is it that test frameworks introduce options like AreEquals, IsNotNull, and especially IsFalse? I feel I spend too much time thinking about which Assert to use when I write unit tests.

  • No-overflow cast on x64

    - by Cheeso
    I have an existing C codebase that works on x86. I'm now compiling it for x64. What I'd like to do is cast a size_t to a DWORD, and throw an exception if there's a loss of data. Q: Is there an idiom for this? Here's why I'm doing this: A bunch of Windows APIs accept DWORDs as arguments, and the code currently assumes sizeof(DWORD)==sizeof(size_t). That assumption holds for x86, but not for x64. So when compiling for x64, passing size_t in place of a DWORD argument, generates a compile-time warning. In virtually all of these cases the actual size is not going to exceed 2^32. But I want to code it defensively and explicitly. This is my first x64 project, so... be gentle.
