  • Accidentally created VB.NET project instead of C#

    - by Bryan M.
    This should seem simple enough, but can't figure it out. I was porting a project out of MonoDevelop and into VS2008, but I accidently created the project as VB.NET instead of C#. Now ReSharper and any syntax highlighting is throwing a fit because it's trying to validate it as VB. How do I tell it to treat it as a C# project without creating a whole new one?

  • User control blank on form in VS 2008

    - by Eric
    I've created a user control that contains a table layout control with various other standard controls like buttons and labels. Yet when I add the user control to one of my forms the control is blank. I've tried building the solution and a see the user-control flicker as if it's being updated, but it remains blank. Also if I actually run the program the usercontrol can not be see on the form. I've used usercontrols like this in the past. Is there something I'm missing?

  • VLC player event catch

    - by user350632
    In my C# application i need to trigger some events when a VLC player (preferably) starts playback (a play button is pressed in VLC for example).Tried Windows Media Player classic with Microsoft Spy++ and observed messages that are sent when playback starts\repeats but i don't know how i could "catch" those messages in my C# code.So my question: is there any way to hook up to event in VLC (or WMP) and get notified about playback status (play, stop, start of repeat). My goal is to create a C# function that waits for start of playback event in player and then triggers some actions in my application (this should also happen when playback ends and starts repeating). What approach should i take here? Just to clearify: I don't want to embedded a new instance of VLC in my app, but instead control/read the "real" full version of VLC, started seperatly by the user

  • 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

  • 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?

  • 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" % ... Default.aspx.cs file: ... using System.Data.SqlClient; using System.Security.Principal; namespace AddFileToSQL { public partial class AddFileToSQL : System.Web.UI.Page { ...

  • Looking for a good C++ based RSS API

    - by Rhubarb
    I tried http://code.google.com/p/feed-reader-lib but holy cow, talk about difficult to build. It has a nightmare of dependencies on Xerces and Xalan, both of which seem to be choking under the new VisualStudio 2010 C++ compiler. I've wasted hours trying to build this thing which is a shame. Does anyone have anything a little easier to hit the ground running with?

  • httpCookie cause the page not to load

    - by jvcoach23
    I'm using VS 2010, vb.net and asp 3.5. I have a simple default.aspx page that has Dim ctx As HttpContext = HttpContext.Current Dim cookie As HttpCookie = ctx.Request.Cookies("SessionGUID") Me.lbl1.Text = cookie.Value.ToString the page loads fine when running it from within VS, but when i build the site and run the page, it doesn't load.. it doesn't give me an error, but nothing shows up. This is what the view source looks like HTMLHEAD META content="text/html; charset=windows-1252" http-equiv=Content-Type/HEAD BODY/BODY/HTML I took out the < in the tags so that it would display here... If i take out the Me.lbl1.Text = cookie.Value.ToString the page loads fine.. All i'm putting to the page is some text and the label control. anyone have any ideas

  • Application settings methods? c++

    - by flyout
    I am thinking about adding configurable settings to an application, and I think the easiest ways are an external file or win registry (its a win only app). Which way would be better? I was wondering, an user with not enough permissions may not be able to create/write the config file. And in the case of the registry, would todays antivirus allow me to add/edit/remove keys? Or they only monitor certain keys? Also, if someone knows a class/lib to manage config settings (in pure win32) in vc++ please post it.

  • Which compiler option I should choose?

    - by Surjya Narayana Padhi
    Hi Geeks, I have to use the third party static library for my qt application to run on windows. The third party provides me a .lib and .h file for use. These libraries are compiled with MSVC compiler. My qt Creator is using MinGW compiler to compile my application. I copied the .h and .lib file to my qt project directory and then added those in .pro file as follows QT += core gui TARGET = MyTest TEMPLATE = app LIBS += C:\Qt\2010.05\qt\MyTest\newApi.lib SOURCES += main.cpp\ mainwindow.cpp HEADERS += mainwindow.h \ newApi.h FORMS += mainwindow.ui Now I am getting some runtime error like this - Starting C:\Qt\2010.05\qt\MyTest-build-desktop\debug\MyTest.exe... C:\Qt\2010.05\qt\MyTest-build-desktop\debug\MyTest.exe exited with code -1073741515 Can any body suggest is this runtime error is due to mismatch of compiler? (because of my .lib file I added is comipled in MSVC compiler and my qt app is compiled using MinGW compiler) If not what may be the reason? Am I missing anything in adding the .h and .lib file to my qt project? If my MinGW compiler will not support the .lib file generated in MSVC compiler what may be the work-arround? Can I create the .lib files in MinGW compiler? or this format is supported only by MSVC compiler only? Please suggest...

  • 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(); } }

  • Managing project configurations in VS 2010

    - by Toby
    I'm working on a solution with multiple projects (class libraries, interop, web application, etc) in VS2010. For the web application, I would like to take advantage of the config transformations in VS2010, so at one point I added configurations for each of our environments: Development, Test, Production, and so on. Some time later, after having rearranged the project layout, I noticed that some projects show all of the configurations in the properties page dropdown. Some projects (added since I did that setup) show only the standard Debug & Release configurations. Once I realized that this was going to make build configurations worse, not better, I decided to remove all of the extra configurations I had added. I've removed all of the various configuration options from the solution, but the projects that had the alternate configuration options still have them, and I can't figure out how to get rid of them in individual projects. Also, now that I see that not all projects have to have the same configurations, I would like to create my environmental configurations at the solution level, and in the web application project (for the config transforms), but leave all of the class libraries with the basic Debug/Release configurations. I've been unable to find any tool in the UI, or any information on the 'Net, concerning how to set up such a thing. So, in short, what's the best/easiest way to manage configurations at the project level in VS2010?

  • VS.NET 2008 - Stop Giving me a Table Adapter.......

    - by mdjtlj
    I'm trying to see if there is a way to stop VS.NET 2008 from doing something which is very annoying to me and our particular standards of coding. When you create a blank dataset and then drag over from the server a table (or tables), VS.NET automatically creates a table adapter for that table, puts the connection information into the XML definition of the XSD and also puts a setting on the property to this database. This requires us to delete the table adapter, get rid of the connection info the XSD file and then go delete the local setting which has been added to the project. I know that I could probably leave all of that stuff and not use it, but that just seems wrong and bloated. Any idea on how to turn this off?

  • 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?

  • Entity Framework insert error ("The Version field is required.")

    - by Graham
    I am using Silverlight 4 and RIA services. When I try to insert into my database, I get the following error: "Submit operation failed validation. Please inspect Entity.ValidationErrors for each entity in EntitiesInError for more information." Upon inspecting the ValidationErrors, I see: "The Version field is required." Isn't the Version field updated and maintained by the framework? If so, why is it null? If not, how am I supposed to set it?

  • 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
