  • Implementing sub fields in a PropertyGrid

    - by evolve
    Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.

  • XML multiline comments in C# - what am I doing wrong?

    - by Dave
    According to this article, it's possible to get multiline XML comments -- instead of using ///, use /** */. This is my interpretation of what multiline comments are, and what I want to have happen: /** * <summary> * this comment is on line 1 in the tooltip * this comment is on line 2 in the tooltip * </summary> */ However, when I use this form, the tooltip that pops up when I hover over my class name in my code is single-line, i.e. it looks exactly as if I had written my comment like this: /// <summary> /// this comment is on line 1 in the tooltip /// this comment is on line 2 in the tooltip /// </summary> Is this behavior actually possible still in VS2008?

  • Including javascript files from other projects inside the same solution

    - by gnomixa
    I have a project called WebResources where I have all the JS files that I intend to use in 2 other projects (all three projects sit in the same solution). I just spent 2 hours playing around with the file paths and VS just doesn't see the JS file (unless I specify the full path with the drive letter). Is there a trick to including javascript files relatively from other projects? My file structure is something like: Project1 Default.aspx Project2 WebResourcesProject /js testToInclude.js No matter how I try to include testToInclude.js inside Default.aspx, VS doesn't see it. Any ideas?

  • Do I have to remove VS 2010 beta1 in order to get a web app to work on asp.net 2.0?

    - by Galilyou
    I think the title is enough :). I have VS 2010 beta1 installed, and I wish to run an asp.net mvc application on my local IIS. The problem is, the asp.net 4.0 runtime is selected by default for all the web sites, when I try to change it to asp.net 2.0, I get the following error message: I click yes, then ok, and when I get back to the ASP.NET tab of my site's properties, I see the 4.0 version is selected back again! Do I have to remove VS 2010 in order to get this to work? (hopefully not) Ps: I'm using windows XP and IIS 5.1

  • Is there a strategy to back-port C# code?

    - by ianmayo
    Hi all, I intend using the Argotic framework in support of a .Net Atom server. Unfortunately my target server (over which I have no control) only has .Net 1.1 - any the Argotic library is only in .Net 2 and 3.5. So, I now need to back-port the code to 1.1. Can anybody provide any strategic tips for this undertaking? I'm aware of the merits of using Unit Tests to verify the ported code (here). should I be looking for automated tools? should I just import the code into VS2003 .Net 1.1 project and work through the compiler warnings? Any tips appreciated. cheers, Ian

  • Struct sockaddr, sin_family is not a member

    - by leon22
    According to this article from msdn ( http://msdn.microsoft.com/en-us/library/windows/desktop/ms740496(v=vs.85).aspx) the struct varies depending on which protocol is selected! Now I want to use this code from http://www.intelliproject.net/articles/showArticle/index/check_tcp_udp_port to check if a port is open or not! Now I have the struct sockaddr as follows: struct sockaddr { ushort sa_family; char sa_data[14]; }; but need this strcuture: struct sockaddr { short sin_family; u_short sin_port; struct in_addr sin_addr; char sin_zero[8]; }; Which changes are necessary? (Ws2_32.lib is linked and following includes #define WIN32_LEAN_AND_MEAN // sockets #include "windows.h" #include <winsock2.h> #include <ws2tcpip.h> Thx

  • Refactoring tools for namespaces and physical project structure

    - by simendsjo
    When I hack around, some code tend to get much bigger than originally planned. As this happens I usually introduce/collapse/merge namespaces, move files between them, move folders etc etc. Sometimes, if I don't have a clear picture of the end result, this is a real pain and really easy to just "skip". This leads the project deteriorate where classes belong elsewhere, strange namespaces, no folders/wrong folders etc. And then I usually cannot take it anymore and do a larger cleanup - which is usually not difficult, just very tedious and it feels nice to do everything at once, so I do a code freeze while finishing up. So my question is... Are there any tools to help refactoring the namespace/physical aspects of a project?

  • Adding Runtime Intelligence Application Analytics for a library and not an application

    - by brickner
    I want to add usage statistics for a .NET 4.0 library I write on CodePlex. I try to follow the step described here but my problem lies with the fact that what I write is a library and not an application. One of the steps is put the Setup and Teardown attributes. I thought about adding the Setup attribute on a static constructor or a different place that will run once per usage of the library. My problem lies with the Teardown attribute that should be placed on code that ends the usage. I don't know where to put this attribute. Is it possible to get usage statistics on a library? Maybe I can register on an event that will fire when the application unloads the dll?

  • MSVCRTD.lib(cpu_disp.obj) : warning LNK4210: .CRT section exists; there may be unhandled static init

    - by Johan
    Hi I know this question has popped up before but I could not find a good answer so I try here. I have a pure C dll (Win32) and I get this warning when compiling: MSVCRTD.lib(cpu_disp.obj) : warning LNK4210: .CRT section exists; there may be unhandled static initializers or terminators Everything seems to work just fine but I am concerned about this warning since I do not understad it. I have quite a few static variables but I do not understand what ".CRT section exist" means. What approach should I take to eliminate this warning. When I try to add the libs msdn suggests I get a ton of linker errors.

  • where does a novice begin with error logging in asp.net c# ?

    - by korben
    i'm a novice teaching myself asp.net in c# via trial and error learn by doing, unfortunately this means lots of errors! i have a custom errors page now that is basically a 404 so that site visitors don't get that ugly application error message .NET throws, but i WOULD like to be able to see what's going wrong myself as people use the site. so i'm looking to build or learn from a fairly basic error logging c# class, that will send the same information given in a browser when hitting a .NET error, send this into a TXT file and email me the error at the same time would be great i don't know where to even begin, can someone give me some pointers? an open source class that does this already that i could plugin and play with would work as well. otherwise some links or guidance on where to start reading would be great too. i sort of have a mental block on understand msdn info-dump pages though, i'm hoping to find some articles on real people talking about implementing the same thing themselves or something like that please note i'm not looking to use some extensive or complicated third party service for this, i'm hoping to learn from the process of implementing a concise customized one

  • Hide/Show problems on a questionerre application

    - by T. Todd
    I am doing an assignment involving the creation of a simple Quiz type form application. However, whenever I run the program, only the first answer shows for a multiple question and I cannot for the life of me figure out why. This is the contstructor: MultipleChoice dlg = new MultipleChoice( new Question("What is the capital of Zimbabwe?", new Answer("Paris", false), new Answer("Washington D.C.", false), new Answer("Harare", true), new Answer("Cairo", false), new Answer("N'Djamena", false))); if (dlg.ShowDialog() == DialogResult.OK) { if (dlg.Correct) MessageBox.Show("You got something right!"); else MessageBox.Show("You couldn't be more wrong"); } And this is the Question Form Code: private Question Q; public MultipleChoice (Question q) { Q = q; InitializeComponent(); textPrompt.Text = Q.Prompt; if (Q.A != null) { radioA.Text = Q.A.Prompt; } else radioA.Hide(); if (Q.B != null) { radioB.Text = Q.B.Prompt; } radioB.Hide(); if (Q.C != null) { radioC.Text = Q.C.Prompt; } radioC.Hide(); if (Q.D != null) { radioD.Text = Q.D.Prompt; } radioD.Hide(); if (Q.E != null) { radioE.Text = Q.E.Prompt; } radioE.Hide(); } public bool Correct { get { if (Q == null) return false; if (Q.A != null && Q.A.Correct && radioA.Checked) return true; if (Q.B != null && Q.B.Correct && radioB.Checked) return true; if (Q.C != null && Q.C.Correct && radioC.Checked) return true; if (Q.D != null && Q.D.Correct && radioD.Checked) return true; if (Q.E != null && Q.E.Correct && radioE.Checked) return true; return false; } Where have I gone wrong?

  • header correct, but identifier not found

    - by sciloop
    I`m having two projects (x64). A. written in C (wxWidgets) B. written in c++ A compiles fine. B uses funcions of A. When I try to compile, I`m getting several errors. I suggest that the reason for the errors is the same for all, so I mention only the first: It says: strlen: identifier not found. But I have included the headers: #include <stdio.h> #include <string.h> So, currently, I have just no idea where to start to search for the reason of the errors. May it be that I have c and c++ files? May it be that I compile for x64? Thanks for help!

  • How can I embed images within my application and use them in HTML control?

    - by Atara
    Is there any way I can embed the images within my exe (as resource?) and use it in generated HTML ? Here are the requirements: A. I want to show dynamic HTML content (e.g. using webBrowser control, VS 2008, VB .Net, winForm desktop application) B. I want to generate the HTML on-the-fly using XML and XSL (file1.xml or file2.xml transformed by my.xsl) C. The HTML may contain IMG tags (file1.gif and or file2.gif according to the xml+xsl transformation) and here comes the complicated one: D. All these files (file1.xml, file2.xml, my.xsl, file1.gif, file2.gif) should be embedded in one exe file. I guess the XML and XSL can be embedded resources, and I can read them as stream, but what ways do I have to reference the image within the HTML ? <IMG src="???" /> I do not want to use absolute path and external files. If the image files are resources, can I use relative path? Relative to what? (I can use BASE tag, and then what?) Can I use stream as in email messages? If so, where can I find the format I need to use? http://www.websiteoptimization.com/speed/tweak/inline-images/ are browser dependent. What is the browser used by webBrowser control? IE? what version? Does it matter if I use GIF or JPG or BMP (or any other image format) for the images? Does it matter if I use mshtml library and not the regular webBrowser control? (currently I use http://www.itwriting.com/htmleditor/index.php ) Does it matter if I upgrade to VS 2010 ? Thanks, Atara

  • .NET MVC Code Generation

    - by Josh
    Is there a way to force the MVC automatically generated code to follow the conventions you have set in your preferences? For example, I keep all curly braces on the same lines as their declaring class, method, etc, but when generating a controller, it completely disregards my settings. Is there a setting someplace to force the same code generation as other parts of project?

  • Link error for user defined class type template parameter

    - by isurulucky
    Hi, I implemented a Simple STL map in C++. Factored out the comparison as a type as I was instructed to, then implemented the comparison as shown below: template <typename T> int KeyCompare<T>::operator () (T tKey1, T tKey2) { if(tKey1 < tKey2) return -1; else if(tKey1 > tKey2) return 1; else return 0; } here, tKey1 and tKet2 are the two keys I'm comparing. This worked well for all the basic data types and string. I added a template specialization to compare keys of a user defined type named Test and added a specialization as follows: int KeyCompare<Test>::operator () (Test tKey1, Test tKey2) { if(tKey1.a < tKey2.a) return -1; else if(tKey1.a > tKey2.a) return 1; else return 0; } when I run this, I get a linking error saying SimpleMap.obj : error LNK2005: "public: int __thiscall KeyCompare::operator()(class Test,class Test)" (??R?$KeyCompare@VTest@@@@QAEHVTest@@0@Z) already defined in MapTest.obj SimpleMap.obj : error LNK2005: "public: __thiscall KeyCompare::~KeyCompare(void)" (??1?$KeyCompare@VTest@@@@QAE@XZ) already defined in MapTest.obj SimpleMap.obj : error LNK2005: "public: __thiscall KeyCompare::KeyCompare(void)" (??0?$KeyCompare@VTester@@@@QAE@XZ) already defined in MapTest.obj MapTest.cpp is the test harness class in which I wrote the test case. I have used include guards as well, to stop multiple inclusions. Any idea what the matter is?? Thank you very much!!

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?
