  • Simplest way to use a DatagridView with Linq to SQL

    - by Martín Marconcini
    Hi, I have never used datagrids and such, but today I came across a simple problem and decided to "databind" stuff to finish this faster, however I've found that it doesn't work as I was expecting. I though that by doing something as simple as: var q = from cust in dc.Customers where cust.FirstName == someString select cust; var list = new BindingList<Customer>(q.ToList()); return list; Then using that list in a DataGridView1.DataSource was all that I needed, however, no matter how much I google, I can't find a decent example on how to populate (for add/edit/modify) the results of a single table query into a DataGridView1. Most samples talk about ASP.NET which I lack, this is WinForms. Any ideas? I've came across other posts and the GetNewBindingList, but that doesn't seem to change much. What am I missing (must be obvious)? Thanks in advance. Martin.

  • How can i create a submitable form that contains dynamically added and removed controls

    - by bill
    Hi All, I am trying to create a form that is made up of controls with values that represent an entity with multiple child entities. The form will represent a product with multiple properties where the user will then be able to create options with multiple properties which in turn be able to create multiple option-items with multiple properties. My question is what is the best approach? Can i use ajax to avoid postbacks and having to rewrite the controls to the page? If i dynamically add the controls in the form of table rows or grid rows will the data/control values be available in the code-behind when i submit? This is an age old question.. the last time i had to do this was .Net 2.0, pre-ajax (for me) and i was forced to recreate all the controls on each post back. thanks!

  • Max tcp/ip connections on Windows Server 2008

    - by zendar
    I have .Net service that listens on single port over TCP protocol. Clients connect and then transmit data for some time (from few minutes to several hours). Is there any limit on number of connections on Windows 2008 server? I did not hit any, since now there is up to 50 users. Plan is to have thousands of users, so I'd like to know if there will be problems in future. Edit: As Cloud answered, it seems that there are some limits in some versions of Windows Server 2008. Is there any reference on those limits? I tried Google, but it returns articles on limit on half-bound tcp connections.

  • Regex for Searching for Text Not Preceeded By a Specific String

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

  • Can't figure out how to code my css

    - by JF
    Hi, I'm a new poster in stackoverflow. The community seems really nice so I'll go ahead and post my question. I'm trying to style a asp.net MVC2 form so that instead of having all the fields on a strait line, I would like to have it like so: Label: Text field Label: Text field I know you could do that with a table but I would like to use CSS to accomplish that. I know a little bit about css but not enough to figure out what to do. The only thing I came close to was to but my fields as a unorder list then styling the li item. Thank you for your help!

  • Posting data to a HttpHandler greater then ~29MB gives a 404 error

    - by Vaibhav Garg
    I am testing a HttpHandler that accepts XML. It works fine when a small amount of data is posted but if I post data larger then approx 29mb, I get a asp.net 404 Error. I am posting to the handler from another handler in the same project and I have tried 2 methods - 1. HttpWebRequest with "POST" 2. WebClient with UploadFile() and UploadData() I get the same 404 error when the posted data is above 29mb. I also tried putting a breakpoint right in the beginning of the receiving handler and debugging. It is never hit. Appears like the handler was never called. Works ok for smaller sized data. What am I doing Wrong? (Thanks in advance for helping)

  • Why Microsoft not provide for C# a static Win32 class with the most native functions and structures

    - by Oleg
    Everybody who used P/Invoke of Windows API knows a long list of declarations of static functions with attributes like [DllImport ("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] The declaration of structures copied from Windows headers like WinNT.h or from web sites like www.pinvoke.net take also a lot of place in our programs. Why we all have to spend our time for this? Why Microsoft not give us a simple way to include a line like in old unmanaged programs #include <windows.h> and we would be have access to a static class Native with all or the most Windows functions and structures inside?

  • Layered Architecture and Static Methods

    - by BigBoss
    I need suggestion for three layered architecture I am planning to implement. Scenario Am Working in ASP.NET c# 3.5 Environment. DLHelper: Methods to get data from database. DAL : Contains Methods which collects data from database with help of DLHelper classes. Most of the methods in this layer are not referencing any page level object, hence can be declared static. BL : Same as DAL Layer, most of the methods are not referencing any page other page level object, hence can be declared static. UI Layer: As per above scenario UI Layer call to BL Layer is like BLClass.Method - DALClass.Method Question I would like to know is this standardise way to do it. As per discussion with my co-worker, we should have corresponding object of BL/DAL layer. But am still looking for more convencing answer.

  • Hooking into DirectX application

    - by x3ro
    Hey there :) I'm currently trying to display some information (as an overlay) to the user inside a DirectX-based game, much like the frame count which Fraps displayed, but I have no clue where to start. I don't expect a full solution to my problem, just a few hints where I can start and where to get more information about the topic ;) Thanks in advance. PS: The project I'm working on is written in C# (.NET 3.5) PPS: To clarify: I mean hooking into any random DX-based game. Start my app, start any game, display some kind of overlay.

  • Using Response.Redirect() to a relative path.

    - by Bryan
    I'm working with ASP.net. My website is hosted within a subfolder test under the IIS root directory. So the url of default.aspx is http://localhost/test/Default.aspx. From default.aspx, I want to use Reponse.Redirect() with a relative path to redirect to another url within the same web site, http://localhost/test/whatever. I tried Response.Redirect("/hello"); and Response.Redirect("~/hello"); Both of them redirect to http://localhost/whatever. Note that the Redirect method use http://localhost instead of http://localhost/test/ as the base url. Any ideas? Thanks.

  • IIS7 Overrides customErrors when setting Response.StatusCode?

    - by Nicholas H
    Having a weird problem here. Everybody knows that if you use web.config's customErrors section to make a custom error page, that you should set your Response.StatusCode to whatever is appropriate. For example, if I make a custom 404 page and name it 404.aspx, I could put <% Response.StatusCode = 404 % in the contents in order to make it have a true 404 status header. Follow me so far? Good. Now try to do this on IIS7. I cannot get it to work, period. If Response.StatusCode is set in the custom error page, IIS7 seems to override the custom error page completely, and shows it's own status page (if you have one configured.) Has anyone else seen this behavior and also maybe know how to work around it? It was working under IIS6, so I don't know why things changed. Update: This is not the same as the issue in http://stackoverflow.com/questions/347281/asp-net-custom-404-returning-200-ok-instead-of-404-not-found

  • How do you modify a modal popup from ASP codebehind instead of letting it close?

    - by user328422
    I'm using SimpleModal to create a popup on an ASP.net application. The OK button calls a server-side function - and based on the resulta of that function I'd like to modify the popup (make some things visible, etc.) instead of letting it close. If that's too difficult, I'd like to open the popup again without the user having to re-click on anything. I'm just not sure what the best way to do this is. Currently the OK button in the popup looks like this: <asp:ImageButton ID="submitInfoBtn" OnClick="btnSubmitInfo_Click" ImageUrl="css/assets/btn_ok.png" runat="server"/> and there is nothing defined that tells anything that the OK button should close the popup (the Cancel button has class="simplemodal-close", so I would expect it to do just that, but not the OK button) - anyone have any ideas on the best way through this? Thanks in advance!!

  • Entity Framework 4.1 (Code First) audit column

    - by Ken Pespisa
    I'm using Entity Framework 4.1 with a Code-First approach on an ASP.NET MVC site Say I have an entity named Profile that keeps track of a user's favorite book, and I want to track when the user updates their favorite book. UPDATED: Using the class below as an example, I want to set the FavoriteBookLastUpdated property to the current date whenever the value of the FavoriteBook property changes. public class Profile { public int Id { get; set; } public string Name { get; set; } public string FavoriteBook { get; set; } public DateTime? FavoriteBookLastUpdated { get; set; } } Right now I just update that field, if appropriate, in the controller's Edit action before calling the DBContext's SaveChanges() method. Is there a way I can put that logic in my model somehow? I'd prefer not to use triggers on the database side.

  • An image from byte to optimized web page presentation

    - by blgnklc
    I get the data of the stored image on database as byte[] array; then I convert it to System.Drawing.Image like the code shown below; public System.Drawing.Image CreateImage(byte[] bytes) { System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(bytes); System.Drawing.Image image = System.Drawing.Image.FromStream(memoryStream); return image; } (*) On the other hand I am planning to show a list of images on asp.net pages as the client scrolls downs the page. The more user gets down and down on the page he/she does see the more photos. So it means fast page loads and rich user experience. (you may see what I mean on www.mashable.com, just take care the new loads of the photos as you scroll down.) Moreover, the returned imgae object from the method above, how can i show it in a loop dynamically using the (*) conditions above. Regards bk

  • Javascript culture always en-us

    - by LoveMeSomeCode
    I'm not sure if I understand this code or if I'm using it right, but I was under the impression that in an ASP.NET 2.0 AJAX website I could run javascript like: var c = Sys.CultureInfo.CurrentCulture and it would give me the culture/language settings the user had specified in their browser at the time of the visit. However, for me, it always comes back 'en-US' no matter what language I pick in firefox or IE. This serverside code however: string[] languages = HttpContext.Current.Request.UserLanguages; if (languages == null || languages.Length == 0) return null; try { string language = languages[0].ToLowerInvariant().Trim(); return CultureInfo.CreateSpecificCulture(language); } catch (ArgumentException) { return null; } does return the language I have currently set. But I need to do this clientside, because I need to parse a string into a datetime and do some validations before I postback, and the string could be a MM/DD/YYYY or DD/MM/YYYY, or some other such thing. What am I missing?

  • Documents/links on preventing HTML form fiddling?

    - by larryq
    Hi everyone, I'm using ASP.Net but my question is a little more general than that. I'm interested in reading about strategies to prevent users from fooling with their HTML form values and links in an attempt to update records that don't belong to them. For instance, if my application dealt with used cars and had links to add/remove inventory, which included as part of the URL the userid, what can I do to intercept attempts to munge the link and put someone else's ID in there? In this limited instance I can always run a check at the server to ensure that userid XYZ actually has rights to car ABC, but I was curious what other strategies are out there to keep the clever at bay. (Doing a checksum of the page, perhaps? Not sure.) Thanks for your input.

Now what i need is to keep the previously selected radio button as checked after the page is postbacked. How do i do that ?

  • Developing for mobile devices and desktop

    - by Augusto
    Hi, I'm starting a new project. It will run on devices running Windows CE, Windows Mobile 6 and will also have a desktop version. The software will connect to some equipments through the serial port, using it's own protocol. Basically it will: connect to the equipment send and receive info read and write binary files These tasks will be shared between desktop and mobile devices. I've been searching the information I need, but I still have some doubts: If I target Windows CE devices it will work with Windows Mobile 6 too? Creating a class library targeting Windows CE will give me any trouble on using it in the desktop version? (when I add a reference to that class library, my VS says that I could experience some unexpected results) Is it possible to install .NET CF 3.5 on devices running Windows CE 4.2? Thanks!

  • Creating a skin engine in MVC

    - by Joe
    Does anyone have any experience creating a skin engine for asp.net MVC? I know the suggested approach is to use flexible markup with CSS, but I would like the ability for a new view to be dropped in, and the application use that one instead of the default one. Basically, I want to know how to tell the framework (at run time) to look into a specific folder for the views/content, and if the item isn't there to check the default locations. I started to look into how the Oxite blog engine does it, but it seems like that might be a bit much for what I need (I am still looking through it, so I could be wrong.) Any help is appreciated.

  • What is the simplest, but solid, interface from WinForms to a SQL Server database?

    - by Greg
    Hi, If I wanted to have my data in SQL Server, but wanted to use a thick client WinForms application for users, what would be the best practice way to have calls occurring from WinForms to database? And how simple is this? I guess I'm trying to gauge to what extent there are issues with this approach and one needs to go for some (a) middle tier with web services, or (b) have to go asp.net or something. I really just have a simple app that needs a database and I'll only have a 10 - 30 clients on a LAN/WAN network that would be connecting in.

  • How to call memcmp() on two parts of byte[] (with offset)?

    - by brickner
    Hi, I want to compare parts of byte[] efficiently - so I understand memcmp() should be used. I know I can using PInvoke to call memcmp() - http://stackoverflow.com/questions/43289/comparing-two-byte-arrays-in-net But, I want to compare only parts of the byte[] - using offset, and there is no memcmp() with offset since it uses pointers. int CompareBuffers(byte[] buffer1, int offset1, byte[] buffer2, int offset2, int count) { // Somehow call memcmp(&buffer1+offset1, &buffer2+offset2, count) } Should I use C++/CLI to do that? Should I use PInvoke with IntPtr? How? Thank you.

  • Date in textboxes changing format

    - by AWinters
    I have an application (asp.net 3.5) that support 4 different languages. Along with other cultural changes, the date formats must match the current culture on out reporting pages. We set the date formats of each of the textboxes like: string date = DateTime.Today.ToString("d"); //returns the date portion only textbox1.Text = date; textbox2.Text = date; etc... When the user selects Spanish or British English the format should be dd/mm/yyyy. However, then I navigate to the page it displays in mm/dd/yyyy. After a postback it then displays dd/mm/yyyy. After another postback it switches to the mm/dd/yyyy format and on and on. I have debugged through this and I see that the culture is correct for the application and the date formats are returned to me correctly, yet when it displays, it displays incorrectly. Has anyone ever seen this or know what is happening?

  • Images' site don't loading with a specific url in mvc

    - by Ivan90
    Hi guys, I'm using ASP.NET MVC 1.0 and I try to create a personal blog! I have a problem with an url that it has to show all post wrote in a specific year and specific month. My url is look like(http://localhost:2282/Blog/Archive/2010/5). So... it work correctly, infact it show all record that have year=2010 and month=5 but my problem is that when I use this url, images in total my site are no longer loading. I have this problem only with this url's type. I think that the problem maybe is my maproute? routes.MapRoute( "ArchiveRoute", "Blog/Archive/{anno}/{mese}", new { controller = "Blog", Action = "Archive",anno = @"\d{4}", mese = @"\d{2}" } ); Why images don't loading with this url? Thanks

  • How to run an executable as a system service?

    - by byanity
    I've got a file and data distribution application written in .NET 2.0 I've written similar to Steam. This application will need to run in Windows 7 and will need to be able to run and install applications that require administrator rights. However the users will not have admin rights. My thought was to run the application as a Local System Service. I figured by doing this the application could perform admin rights actions (registry edits, launching apps, etc) when the user isn't an admin. Are my assumptions correct? What steps do I need to take to have this app install as a Local System Service? An Administrator will be installing the application but it will be run by a user without Administrator rights. Thanks in advance!
