  • Linux System Programming

    - by AJ
    I wanted to get into systems programming for linux and wanted to know how to approach that and where to begin. I come from a web development background (Python, PHP) but I also know some C and C++. Essentially, I would like to know: Which language(s) to learn and pursue (I think mainly C and C++)? How/Where to learn those languages specific to Systems Programming? Books, websites, blogs, tutorials etc. Any other good places where I can start this from basics? Any good libraries to begin with? What environment setup (or approx.) do I need? Assuming linux has to be there but I have a linux box which I rarely log into using GUI (always use SSH). Is GUI a lot more helpful or VI editor is enough? (Please let me know if this part of the question should go to serverfault.com) PS: Just to clarify, by systems programming I mean things like writing device drivers, System tools, write native applications which are not present on Linux platform but are on others, play with linux kernel etc.

  • update datagridview using ajax in my asp.net without refreshing the page.(Display real time data)

    - by kurt_jackson19
    I need to display a real time data from MS SQL 2005. I saw some blogs that recommend Ajax to solve my problem. Basically, right now I have my default.aspx page only just for a workaround I could able to display the data from my DB. But once I add data manually to my DB there's no updating made. Any suggestions guys to fix this problem? I need to update datagridview with out refreshing the page. Here's my code on Default.aspx.cs using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { FillDataGridView(); } protected void up1_Load(object sender, EventArgs e) { FillDataGridView(); } protected void FillDataGridView() { DataSet objDs = new DataSet(); SqlConnection myConnection = new SqlConnection (ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString); SqlDataAdapter myCommand; string select = "SELECT * FROM Categories"; myCommand = new SqlDataAdapter(select, myConnection); myCommand.SelectCommand.CommandType = CommandType.Text; myConnection.Open(); myCommand.Fill(objDs); GridView1.DataSource = objDs; GridView1.DataBind(); } } Code on my Default.aspx <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Ajax Sample</title> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> <Scripts> <asp:ScriptReference Path="JScript.js" /> </Scripts> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" OnLoad="up1_Load"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" Height="136px" Width="325px"/> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="GridView1" /> </Triggers> </asp:UpdatePanel> </form> </body> </html> My problem now is how to call or use the ajax.js and how to write a code to call the FillDataGridView() in my Default.aspx.cs page.

  • How do I scrape information off ASP.NET websites when paging and JavaScript links are being used?

    - by Ian Roke
    I have been given a staff list which is supposed to be up to date but it doesn't match an intranet People Finder which is written in ASP.NET. As the information is sensitive I am not able to access the database the People Finder is using so the only way I can get at the information is by scraping the structure starting at the top brass at the top and then going through each tier in turn. Each person has a Staff number which then forms the URL http://intranet/peoplefinder/index.aspx?srn=ABC1234 and then all the people who report to them are listed underneth in the format <a id="gvEmployees_ctl03_lnkFullName" href="index.aspx?srn=ABC4321" target="_self"> where each URL indicates the Staff number and provides a link to their team. The trouble arises when the teams are big as paging is implemented in the GridView with an URL such as <a href="javascript:__doPostBack('gvEmployees','Page$2')">2</a>. How would I scrape this page, capture the SRN and other details along with the people who report to the person on all pages of the GridView then loop through each reportee and do the same process until the whole list is complete?

  • How to best show progress info when using ADO.NET?

    - by Yadyn
    I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

  • How to open child forms positioned within MDI parent in VB.NET?

    - by user961627
    How do we arrange child forms in a parent MDI window? I'm able to call and display a child form from a menu on the parent, but the child pops up outside the parent - I want it to actually be inside the parent. I've checked in C# and VB.Net solutions but they all say pretty much the same, i.e. try to access LayoutMDI, such as here: http://msdn.microsoft.com/en-us/library/x9fhk181.aspx The problem is, where do I access this? When I'm in the code of my MDI parent, Me.LayoutMdi is not recognized. In which part of the application do I put the Me.LayoutMDI code? Edit The Me.LayoutMDI code worked in the parent after all. I'd been trying for a while but don't know where I was going wrong. However, the child continues to pop up out of the parent. Here's an image of how that happens. The broader form in the back is the parent, and the one with the gridview and two buttons is the new child that popped up. I want it to pop up "Docked" within the parent.

  • What is the correct way to create dynamic javascript in ASP.net MVC2?

    - by sabbour
    I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

  • JQuery idleTimeout plugin: How to display the dialog after the session is timedout on ASP.NET MVC Pa

    - by Rita
    Hi I am working on migrating the ASP.NET apllication to MVC Framework. I have implemented session timeout for InActiveUser using JQuery idleTimeout plugin. I have set idletime for 30 min as below in my Master Page. So that After the user session is timedout of 30 Min, an Auto Logout dialog shows for couple of seconds and says that "You are about to be signed out due to Inactivity" Now after this once the user is logged out and redirected to Home Page. Here i again want to show a Dialog and should stay there saying "You are Logged out" until the user clicks on it. Here is my code in Master page: $(document).ready(function() { var SEC = 1000; var MIN = 60 * SEC; // http://philpalmieri.com/2009/09/jquery-session-auto-timeout-with-prompt/ <% if(HttpContext.Current.User.Identity.IsAuthenticated) {%> $(document).idleTimeout({ inactivity: 30 * MIN, noconfirm : 30 * SEC, redirect_url: '/Account/Logout', sessionAlive: 0, // 30000, //10 Minutes click_reset: true, alive_url: '', logout_url: '' }); <%} %> } Logout() Method in Account Controller: public virtual ActionResult Logout() { FormsAuthentication.SignOut(); return RedirectToAction(MVC.Home.Default()); } Appreciate your responses.

  • ASP.NET MVC on Cassini: How can I force the "content" directory to return 304s instead of 200s?

    - by Portman
    Scenario: I have an ASP.NET MVC application developed in Visual Studio 2008. There is a root folder named "Content" that stores images and stylesheets. When I run locally (using Cassini) and browse my application, every resource from the "Content" directory is always downloaded. Using Firebug, I can verify that the web server returns an HTTP 200 ("ok"). Desired: I would like for Cassini to return HTTP 304 ("not modified") instead of 200. This is the behavior when running the site under IIS7. Reasoning: The site I am working on has a large number of static resources (often as many as 40 per page). Browsing the site is very fast on IIS7, because these resources are (correctly) cached by the browser. However, browsing the site on my local machine is painfully slow. Pages that render in under 1 second on IIS7 take over 30 seconds to render on Cassini. It's actually faster for me to upload the entire website every few minutes and test from there. (Yes, I recognize that this is perverse and crazy.) So: how can I instruct/trick Cassini into treating the "Content" directory like IIS7 does?

  • Is there an event that raises after a View/PartialView executes in ASP.NET MVC 2 RC2?

    - by sabanito
    I have the following problem: We have an ASP.NET MVC 2 RC 2 application that programmatically impersonates an AD Account that the user specifies at logon. This account is used to access the DB. At first we had the impersonating code in the begin_request and we were undoing the impersonation at the end_request, but when we tried to use IIS 7.5 in integrated mode, we learned that it's not possible to impersonate in the Global.asax so we tried different things. We have succesfully moved our code from the BeginRequest to the ActionExecuting event and the EndRequest to the ResultExecuted, and now, about 80% of our code works. We've just discovered that since we're passing the Entity Framework objects as models for our views, there's this remaining 20% that won't work because some Navigation Properties are not loaded when the view begins it's execution, so we're getting connection exceptions from Sql Server. Is there any event or method that executes AFTER the view, so we can undo the impersonation in it? We thought ResultExecuted will do just that, but it doesn't. We've been told that passing the plain Entities into the view as models is not a good idea, but we have A LOT of views that may have this problem and there's not automated way to know it. If some of you could explain why it's not a good idea, maybe we can convince the team to fix it!

  • Correct Interactive Website System Design Concepts / Methods?

    - by Xandel
    Hi all, I hope this question isn't too open ended, but a nudge in the right direction is all I need! I am currently building an online accounting system - the idea is that users can register, log in, and then create customers, generate invoices and other documents and eventually print / email those documents out. I am a Java programmer but unfortunately haven't had too much experience in web projects and their design concepts... This is what I have got thus far - A Tomcat web server which loads Spring. Spring handles my DAO's and required classes for the business logic. Tomcat serves JSP's containing the pages which make up the website. To make it interactive I have used JavaScript in the pages (jQuery and its AJAX calls) to send and receive JSON data (this is done by posting to a page which calls a handleAction() method in one of my classes). My question is, am I tackling this project in the right way? Am I using the right tools and methods? I understand there are literally countless ways of tackling any project but I would really love to get feedback with regards to tried and tested methods, general practices etc. Thanks in advance! Xandel

  • Can I have two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain?

    - by Hamman359
    Is it possible to setup two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain? i.e. both point to different pages within www.somesite.com. Here's some background on the application and why I'm asking. This is a brownfield application that is currently 2.0 WebForms and is full of WebFormy 'goodness' (i.e. ObjectDataSources, FormView controls, UpdatePanels, etc...) There are lost of other 'fun' things in the code base like 600+ Stored Procedures and 200+ line methods in the business layer code that get data from the DB via stored proc, do some processing on the data, build an HTML string using string concatenation and then return that string to the UI layer. What we are planning on doing is developing new features in MVC and slowly converting the existing features over to MVC one at a time. As part of this transition, we will also be re-writing the layers below the UI to clean up the mess there and to do things like replace the stored procedures with NHibernate and introduce an IOC container. I know that you can run WebForms and MVC side-by-side in the same project, however, because we will be making wholesale changes to the way we do many things throughout our entire development stack, I'd like the new stuff to be a completely separate project within the solution. This should help serve as very visual reminder that this is a different way of doing things than before and make it easier to remove the old code as it is no longer needed. What I don't know is, is this even possible? Can two separate project point to the same domain? Here's an quick example of what I'm thinking: www.somesite.com/orders.aspx?id=123 (Orders page from existing WebForms project) www.somesite.com/customer/987 (Customer page from new MVC project)

  • Control Attributes render Encoded on dot net 4 - how to disable the encoding ?

    - by Aristos
    I have an issue in asp.net 4. When I add an attribute on controls, then the render it encoded. For example, when I type this code txtQuestion.Attributes["onfocus"] = "if(this.value == this.title) { this.value = ''; this.style.backgroundColor='#FEFDE0'; this.style.color='#000000'; }"; I get render onfocus="if(this.value == this.title){this.value = &#39;&#39;;this.style.backgroundColor=&#39;#FEFDE0&#39;; this.style.color=&#39;#000000&#39;;}" And every ' hash been change to & #39; Is there a way to disable this new future only on some controls ? or an easy way to make a custom render ? My Fail tries I have all ready try some thinks but I fail. For example this fails. txtQuestion.RenderingCompatibility = new Version("3.5"); I also locate the point that this attributes renders and is on public virtual void RenderBeginTag(HtmlTextWriterTag tagKey) function, there every attribute have a flag if he wish to be encoded, but I do not know how can anyone set it or not. Anyway, thank you in advanced.

  • .NET How would I build a DAL to meet my requirments?

    - by Jonno
    Assuming that I must deploy an asp.net app over the following 3 servers: 1) DB - not public 2) 'middle' - not public 3) Web server - public I am not allowed to connect from the web server to the DB directly. I must pass through 'middle' - this is purely to slow down an attacker if they breached the web server. All db access is via stored procedures. No table access. I simply want to provide the web server with a ado dataset (I know many will dislike this, but this is the requirement). Using asmx web services - it works, but XML serialisation is slow and it's an extra set of code to maintain and deploy. Using a ssh/vpn tunnel so that the one connects to the db 'via' the middle server, seems to remove any possible benefit of maintaining 'middle'. Using WCF binary/tcp removes the XML problem, but still there is extra code. Is there an approach that provides the ease of ssh/vpn, but the potential benefit of having the dal on the middle server? Many thanks.

  • ASP.NET MVC jQuery autocomplete with url.action helper in a script included in a page.

    - by Boob
    I have been building my first ASP.NET MVC web app. I have been using the jQuery autocomplete widget in a number of places like this: <head> $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); </head> The thing is I have this jQuery code in a number of different places through my web app. So i thought I would create a seperate javascript script (script.js) where I could put this code and then just include it in the master page. Then i can put all these repeated pieces of code in that script and just call them where I need too. So I did this. My code is shown below: In the site.js script I put this function: function doAutoComplete() { $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); } On the page I have: <head> <script src="../../Scripts/site.js" type="text/javascript"></script> doAutoComplete(); </head> But when I do this I get an Invalid Argument exception and the autocomplete doesnt work. What am I doing wrong? Any ideas?Do i need to pass something to the doAutoComplete function?

  • ASP.NET RangeValidator can't do even the most basic math !?!?!?

    - by marc_s
    I'm having an issue with my ASP.NET RangeValidator controls. I want to allow users to enter a discount amount, and this amount must be negative (< $0.00). I want to verify that the amount entered in a textbox is a negative value, so I have this in my page markup: <asp:TextBox ID="tbxDiscount" runat="server" /> <asp:RangeValidator ID="rvDiscount" runat="server" ControlToValidate="tbxDiscount" MinimumValue="0.0" MaximumValue="0.0" EnableClientScript="true" ErrorMessage="Please enter a negative value for a discount" /> and I attempt to set the MinimumValue dynamically in my code before the page gets rendered - to the negative equivalent of my item price. So if the item is $69, I want to set the minimum value to - $69: rvDiscount.MinimumValue = (-1.0m * Price).ToString(); Trouble is: I keep getting this error message: The maximum value 0.0 cannot be less than the minimum value -69.00 for rvDiscount WTF?!?!??! Where I come from, -69 $ IS less than $0 ...... so what's the problem? And more importantly: what is the solution to the problem??

  • Can I use my Ninject .NET project within Orchard CMS?

    - by Mattias Z
    I am creating a website using Orchard CMS and I have an external .NET project written with Ninject for dependency injection which I would like to use together with a module within Orchard CMS. I know that Orchard uses Autofac for dependency injection and this is causing me problems since I never worked with DI before. I have created a Autofac module UserModule which registers the source UserRegistrationSource and I configured Orchard to load the module like this: OrchardStarter.cs .... builder.RegisterModule(new UserModule()); .... UserModule.cs public class UserModule : Module { protected override void Load(ContainerBuilder builder) { builder.RegisterSource(new UserRegistrationSource()); base.Load(builder); } } UserRegistrationSource.cs public class UserRegistrationSource : IRegistrationSource { public bool IsAdapterForIndividualComponents { get { return false; } } public IEnumerable<IComponentRegistration> RegistrationsFor(Service service, Func<Service, IEnumerable<IComponentRegistration>> registrationAccessor) { var serviceWithType = service as IServiceWithType; if (serviceWithType == null) yield break; var serviceType = serviceWithType.ServiceType; if (!serviceType.IsInterface || !typeof(IUserServices).IsAssignableFrom(serviceType) || serviceType == typeof(IUserServices)) yield break; var registrationBuilder = ... yield return registrationBuilder.CreateRegistration(); } } But now I'm stuck... Should I somehow try to resolve the dependencies in UserRegistrationSource by getting the requested types from the Ninject container (kernel) with Autofac or is this the wrong approach? Or should the Ninject kernel do the resolves for Autofac for the external project?

  • asp.net 4.0 webforms - how to keep ContentPlaceHolder1_ out of client id's in a simple way?

    - by James Manning
    I'm attempting to introduce master pages to an existing webforms site that's avoided using them because of client id mangling in the past (and me not wanting to deal with the mangling and doing <% foo.ClientID % everywhere :) GOAL: use 'static' id values (whatever is in the server control's id attribute) except for data-bound / repeating controls which would break for those cases and therefore need suffixes or whatever to differentiate (basically, Predictable) Now that the site migrated to ASP.NET 4.0, I first attempted to use ClientIDMode of Static (in the web.config) but that broke too many places doing repeating controls (checkboxes inside gridviews, for instance) since they all resulted with the same id. So, I then tried Predictable (again, just in the web.config) so that the repeating controls wouldn't have conflicting id's, and it works well except that the master page content placeholder (which is indeed a naming container) is still reflecting in the resulting client id's (for instance, ContentPlaceHolder1_someCheckbox). Certainly I could leave the web.config setting as static and then go through all the databound/repeating controls switch them to Predictable, but I'm hoping there's some easier/simpler way to get that effect without having to scatter ClientIDMode attributes in those N number of places (or extend all those databound controls with my own usercontrol that just sets clientidmode, or whatever). I even thought of leaving web.config set to static and doing a master or basepage handler (preinit? not sure if that would work or not) that would go walk Controls with OfType<INamingContainer() (might be a better choice on the type, but that seems like a good starting choice looking at repeater and gridview) and then set those to Predictable so I'd get static for all my 'normal' things outside of repeating controls but not have to deal with static inside things like gridview/repeater/etc. I don't see any way to mark the content placeholder such that it 'opts out' of being included in child id's - setting the ID of the placeholder to empty/blank doesn't work as it's a required attribute :) At that point I figured there was a better/simpler way that I was missing and decided to ask on SO :) Edit: I thought about changing all my 'fetch by id' jquery calls from $('#foo') to fetch_by_id('foo') and then having that function return the 'right one' by checking $('#foo').length and then $('#ContentPlaceHolder1_foo').length (and maybe other patterns) or even just have it return $('#foo, #ContentPlaceHolder1_foo') (again, potentially other patterns) but changing all the places I fetch elements by id seemed pretty ugly too, and I'd like to avoid that abstraction layer if possible to do so easily :)

  • Ajax Auto Complete in ASP.Net MVC project - How to display a an object's name but actually save it's

    - by Ben
    I have implemented the Ajax Autocomplete feature in my application using a web service file that querys my database and it works great. One problem I am having is allowing the user to see the item's name, as that's what they are typing in the textbox, but when they select it, it saves the item's ID number instead of the actual name. I want it to behave much like a dropdown list, where I can specify what is seen and entered vs. what is actually saved in the database (in this case, the product ID instead of it's name.) I have this text box in my view, along with the script: <script type="text/javascript"> Sys.Application.add_init(function() { $create( AjaxControlToolkit.AutoCompleteBehavior, { serviceMethod: 'ProductSearch', servicePath: '/ProductService.asmx', minimumPrefixLength: 1, completionSetCount: 10 }, null, null, $get('ProductID')) }); </script> <p> <label for="ProductID">Product:</label> <%= Html.TextBox("ProductID", Model.Products)%> <%= Html.ValidationMessage("ProductID", "*")%> </p> Here's what is in my asmx file: public class ProductService : System.Web.Services.WebService { [WebMethod] public string[] ProductSearch(string prefixText, int count) { MyDataContext db = new MyDataContext(); string[] products = (from product in db.Products where product.ProductName.StartsWith(prefixText) select product.ProductName).Take(count).ToArray(); return products; } } Can anyone help me figure this out? I'm using this so they can just start typing instead of having a dropdown list that's a mile long...

  • Using ASP.NET SQL Membership Provider, how do I store my own per-user data?

    - by Gary McGill
    I'm using the ASP.NET SQL Membership Provider. So, there's an aspnet_Users table that has details of each of my users. (Actually, the aspnet_Membership table seems to contain most of the actual data). I now want to store some per-user information in my database, so I thought I'd just create a new table with a UserId (GUID) column and an FK relationship to aspnet_Users. However, I then discovered that I can't easily get access to the UserId since it's not exposed via the membership API. (I know I can access it via the ProviderUserKey, but it seems like the API is abstracting away the internal UserID in favor of the UserName, and I don't want to go too far against the grain). So, I thought I should instead put a LoweredUserName column in my table, and create an FK relationship to aspnet_Users using that. Bzzzt. Wrong again, because while there is a unique index in aspnet_Users that includes the LoweredUserName, it also includes the ApplicationId - so in order to create my FK relationship, I'd need to have an ApplicationId column in my table too. At first I thought: fine, I'm only dealing with a single application, so I'll just add such a column and give it a default value. Then I realised that the ApplicationId is a GUID, so it'd be a pain to do this. Not hard exactly, but until I roll out my DB I can't predict what the GUID is going to be. I feel like I'm missing something, or going about things the wrong way. What am I supposed to do?

  • How to populate a listview in ASP.NET 3.5 through a dataset?

    Is it possible to populate a listview with a dataset? I have a function that returns a dataset. Why im asking this is because my SQL is quite complicated and i can't convert it to a SQLDataSource... Public Function getMessages() As DataSet Dim dSet As DataSet = New DataSet Dim da As SqlDataAdapter Dim cmd As SqlCommand Dim SQL As StringBuilder Dim connStr As StringBuilder = New StringBuilder("") connStr.AppendFormat("server={0};", ConfigurationSettings.AppSettings("USERserver").ToString()) connStr.AppendFormat("database={0};", ConfigurationSettings.AppSettings("USERdb").ToString()) connStr.AppendFormat("uid={0};", ConfigurationSettings.AppSettings("USERuid").ToString()) connStr.AppendFormat("pwd={0};", ConfigurationSettings.AppSettings("USERpwd").ToString()) Dim conn As SqlConnection = New SqlConnection(connStr.ToString()) Try SQL = New StringBuilder cmd = New SqlCommand SQL.Append("SELECT m.MESSAGE_ID, m.SYSTEM_ID, m.DATE_CREATED, m.EXPIRE_DATE, ISNULL(s.SYSTEM_DESC,'ALL SYSTEMS') AS SYSTEM_DESC, m.MESSAGE ") SQL.Append("FROM MESSAGE m ") SQL.Append("LEFT OUTER JOIN [SYSTEM] s ") SQL.Append("ON m.SYSTEM_ID = s.SYSTEM_ID ") SQL.AppendFormat("WHERE m.SYSTEM_ID IN ({0}) ", sSystems) SQL.Append("OR m.SYSTEM_ID is NULL ") SQL.Append("ORDER BY m.DATE_CREATED DESC; ") SQL.Append("SELECT mm.MESSAGE_ID, mm.MODEL_ID, m.MODEL_DESC ") SQL.Append("FROM MESSAGE_MODEL mm ") SQL.Append("JOIN MODEL m ") SQL.Append(" ON m.MODEL_ID = mm.MODEL_ID ") cmd.CommandText = SQL.ToString cmd.Connection = conn da = New SqlDataAdapter(cmd) da.Fill(dSet) dSet.Tables(0).TableName = "BASE" dSet.Tables(1).TableName = "MODEL" Return dSet Catch ev As Exception cLog.EventLog.logError(ev, cmd) Finally 'conn.Close() End Try End Function

  • Asp.Net MVC - Binding of parameter to model value!

    - by Pino
    This seems like the model binding is causing me issues. Essentially I have a model called ProductOption and for the purpose of this question it has 2 fields ID (Int) PK ProductID (Int) FK I have a standard route set-up context.MapRoute( "Product_default", "Product/{controller}/{action}/{id}", new { controller = "Product", action = "Index", id = UrlParameter.Optional } ); and if the user wants to add an option the URL is, /Product/Options/Add/1 in the above URL 1 is the ProductID, I have the following code to return a blank model the the view, [HttpGet] public ActionResult Add(int id) { return View("Manage", new ProductOptionModel() { ProductID = id }); } Now in my view I keep a hidden field <%= Html.HiddenFor(x=>x.ID) %> This is used to determine (on submit) if we are editing or adding a new option. However the Model binder in .net seems to replace .ID (Which was 0 when leaving the above get actionresult) with 1 (or the value of the id parameter in the URL) How can I stop or work around this? ViewModel public class ProductExtraModel { //Database public int ID { get; set; } public string Name { get; set; } public int ProductID { get; set; } public ProductModel Product { get; set; } }

  • Passing a outside variable into a <asp:sqldatasource> tag. ASP.NET 2.0

    - by MadMAxJr
    I'm designing some VB based ASP.NET 2.0, and I am trying to make more use of the various ASP tags that visual studio provides, rather than hand writing everything in the code-behind. I want to pass in an outside variable from the Session to identify who the user is for the query. <asp:sqldatasource id="DataStores" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>" providername="<%$ ConnectionStrings:MY_CONNECTION.ProviderName %>" selectcommand="SELECT THING1, THING2 FROM DATA_TABLE WHERE (THING2 IN (SELECT THING2 FROM RELATED_DATA_TABLE WHERE (USERNAME = @user)))" onselecting="Data_Stores_Selecting"> <SelectParameters> <asp:parameter name="user" defaultvalue ="" /> </SelectParameters> </asp:sqldatasource> And on my code behind I have: Protected Sub Data_Stores_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles Data_Stores.Selecting e.Command.Parameters("user").Value = Session("userid") End Sub Oracle squaks at me with ORA-01036, illegal variable name. Am I declaring the variable wrong in the query? I thought external variables share the same name with a @ prefixed. from what I understand, this should be placing the value I want into the query when it executes the select. EDIT: Okay, thanks for the advice so far, first error was corrected, I need to use : and not @ for the variable declaration in the query. Now it generates an ORA-01745 invalid host/bind variable name. EDIT AGAIN: Okay, looks like user was a reserved word. It works now! Thanks for other points of view on this one. I hadn't thought of that approach.

  • Is there bug in the Matrix.RotateAt method for certain angles? .Net Winforms

    - by Jules
    Here's the code i'm using to rotate: Dim m As New System.Drawing.Drawing2D.Matrix Dim size = image.Size m.RotateAt(degreeAngle, New PointF(CSng(size.Width / 2), CSng(size.Height / 2))) Dim temp As New Bitmap(600, 600, Imaging.PixelFormat.Format32bppPArgb) Dim g As Graphics = Graphics.FromImage(temp) g.Transform = m g.DrawImage(image, 0, 0) (1) Disposals removed for brevity. (2) I test the code with a 200 x 200 rectangle. (3) Size 600,600 it just an arbitrary large value that I know will fit the right and bottom sides of the rotated image for testing purposes. (4) I know, with this code, the top and left edges will be clipped because I'm not transforming the orgin after the rotate. The problem only occurs at certain angles: (1) At 90, the right hand edge disappears completely. (2) At 180, the right and bottom edges are there, but very faded. (3) At 270, the bottom edge disappears completely. Is this a known bug? If I manually rotate the corners an draw the image by specifying an output rectangle, I don't get the same problem - though it is slightly slower than using RotateAt.
