  • Read only particular fields from CSV File in vb.net

    - by fireBand
    Hi, I have this code to read a CVS file. It reads each line, devides each line by delimiter ',' and stored the field values in array 'strline()' . How do I extract only required fields from the CSV file? For example if I have a CSV File like Type,Group,No,Sequence No,Row No,Date (newline) 0,Admin,3,345678,1,26052010 (newline) 1,Staff,5,78654,3,26052010 I Need only the value of columns Group,Sequence No and date. Thanks in advance for any ideas. Dim myStream As StreamReader = Nothing ' Hold the Parsed Data Dim strlines() As String Dim strline() As String Try myStream = File.OpenText(OpenFile.FileName) If (myStream IsNot Nothing) Then ' Hold the amount of lines already read in a 'counter-variable' Dim placeholder As Integer = 0 strlines = myStream.ReadToEnd().Split(Environment.NewLine) Do While strlines.Length <> -1 ' Is -1 when no data exists on the next line of the CSV file strline = strlines(placeholder).Split(",") placeholder += 1 Loop End If Catch ex As Exception LogErrorException(ex) Finally If (myStream IsNot Nothing) Then myStream.Close() End If End Try

    - by Ashwani K
    Hello All: I have one debugger visualizer for seeing list of class object in the form of data table.

So, can anybody tell me how to make a class Serializable at run time if the class is not marked Serializable. Thanks Ashwani

  • ASP.NET catching controls from html generated from the database

    - by Drahcir
    I have a set of websites that basically do the exact same thing in terms of functionality, the only thing that varies is the css and how the html is laid out. Is there a way to generate the html from a database (ie retreiving the html from a table) and then catching the controls (like buttons, textboxes etc) from the code behind? UPDATE: Here is an example of what I want to acheive: <html> <div id="generatedContent" runat="server"> <!-- the following content has been generated from the database on the page load event --> <div> This is a textbox <input id="tb1" runat="server" type="text" /> This is a button <input type="submit" id="btn1" runat="server" value="My Button" /> </div> </div> </html> This is the code behind var tb1 = new HtmlControls.HtmlInputText(); tb1 = FindControl("tb1"); var btn1 = new New HtmlControls.HtmlInputSubmit(); btn1 = FindControl("btn1"); Now obviously since the html has been generated from the database (ie after the page has already been initialised) the FindControl method will return null.

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

    Could any experienced users of Dynamic Data comment on whether there are issues with it in: Internet Explorer 6 Safari Chrome Opera We are looking to use it on a public facing website and good old IE6 has many important users in government departments and large companies so it has to work there. The other browsers could also become an issue.

  • ASP.NET Threading issue

    - by Danny
    Hope I can explain this correctly. I have a process, that outputs step by step messages (i.e., Processing item 1... Error in item 2 etc etc). I want this to be outputted to the user during the process, and not at the end. I pretty sure i need to do this with threading, but can't find a decent example. Thanks in advanced.

  • How do I 'donut cache' in ASP.NET MVC for something more than a date

    - by Simon_Weaver
    All the examples for donut caching I've seen are just like this : <%= Html.Substitute( c => DateTime.Now.ToString() )%> Thats fine if I just want the date, but what other options are there? I know there is a delegate 'MvcSubstitutionCallback' which has the following signature : public delegate string MvcSubstitutionCallback(HttpContextBase httpContext); but RenderAction and RenderPartial returns void so i cant just return them from the delegate method. How can I effectively use this callback for more complex situations. I've looked at both of Phil Haacked's articles here and here, but neither seems to do exactly what I want.

  • Why .NET Boolean has TrueLiteral and TrueString?

    - by user309937
    Why in Boolean type there are two fields with the same value? internal const int True = 1; internal const int False = 0; internal const string TrueLiteral = "True"; internal const string FalseLiteral = "False"; and public static readonly string TrueString; public static readonly string FalseString; static Boolean() { TrueString = "True"; FalseString = "False"; } in reflector generated code, methods don't use those strings but: public string ToString(IFormatProvider provider) { if (!this) { return "False"; } return "True"; } would't it be better to use those const values?

  • ASP.NET MVC2 and Browser Caching

    - by Dan
    Hi I have a web application that fetches a lot of content via ajax. For example when a user edits some data, the browser will send the changes using an ajax post and then do an ajax get to get fresh content and replace an existing div on the page with that content. This was working just find with MVC1, but in MVC2 I would get inconsistent results. I've found that MVC1 by default included an Expires item in the response headers set to the current time, but in MVC2 the Expires header is missing. This is a problem with some browsers (IE8) actually using the cached version of the ajax get instead of the fresh version. To deal with the problem I created a simple ActionFilterAttribute that sets the reponse cache to NoCache (see below), which works, but it seems kind of sillly to decorate every controller with this attribute. Is there a global way to set this for every controller? Is this a bug in MVC2 and it really should be setting the expires on every ActionResult/view/page? Don't most MVC programs deal with data entry where stale data is a very bad thing? Thanks Dan public class ResponseNoCachingAttribute : ActionFilterAttribute { public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache); } }

  • Deserializing JSON in WCF throws xml errors in .Net 4.0

    - by Syg
    Hi there. I'm going slidely mad over here, maybe someone else can figure out what's going on here. I have a WCF service exposing a function using webinvoke, like so: [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "registertokenpost" )] void RegisterDeviceTokenForYoumiePost(test token); The datacontract for the test class looks like this: [DataContract(Namespace="Zooma.Test", Name="test", IsReference=true)] public class test { string waarde; [DataMember(Name="waarde", Order=0)] public string Waarde { get { return waarde; } set { waarde = value; } } } When sending the following json message to the service, { "test": { "waarde": "bla" } } the trace log gives me errors (below). I have tried this with just a string instead of the datatype (void RegisterDeviceTokenForYoumiePost(string token); ) but i get the same error. All help is appreciated, can't figure it out. It looks like it's creating invalid xml from the json message, but i'm not doing any custom serialization here. The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'RegisterDeviceTokenForYoumiePost'. Unexpected end of file. **Following elements are not closed**: waarde, test, root.</Message><StackTrace> at System.ServiceModel.Dispatcher.OperationFormatter.DeserializeRequest(Message message, Object[] parameters)

It has number of functions, and I understand only few of them, like with connecting to the database or creating a command object but there are 2 that I dont understand: public static DataTable GetTable(string str) { OleDbConnection con = DAL.GetConnection(); OleDbCommand cmd = DAL.GetCommand(con, str); DataTable dt = new DataTable(); OleDbDataAdapter adp = new OleDbDataAdapter(); adp.SelectCommand = cmd; adp.Fill(dt); return dt; } public static int ExecuteNonQuery(string str) { int num = -1; OleDbConnection con = DAL.GetConnection(); con.Open(); if (con.State == ConnectionState.Open) { OleDbCommand cmd = DAL.GetCommand(con, str); num = cmd.ExecuteNonQuery(); con.Close(); } return num; } thank you :)

  • ASP.NET MVC pass information from controller to view WITHOUT ViewData, ViewModel, or Session

    - by josh
    I have a unique scenario where I want a base controller to grab some data and store it in a list. The list should be accessible from my views just as ViewData is. I will be using this list on every page and would like a cleaner solution than just shoving it in the ViewDataDictionary. After attempting to come up with a solution, I thought I would create a custom ViewPage with a property to hold my list. My custom ViewPage would inherit from System.Web.MVC.ViewPage. However, I do not know where MVC passes the viewdata from the controller off to the view. More importantly, how do I get it to pass my list down to the view? Thanks for the help.

  • C# ASP.Net The type or namespace name 'iAnywhere' could not be found

    - by Louis Russell
    Morning all, I know that this sounds like a simple referencing problem from the title this is becoming a nightmare! I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section. Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?) The line that the Error points to this line in the class: using iAnywhere.Data.AsaClient; I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be brilliant!

  • Does the .NET CLR Really Optimize for the Current Processor

    - by dewald
    When I read about the performance of JITted languages like C# or Java, authors usually say that they should/could theoretically outperform many native-compiled applications. The theory being that native applications are usually just compiled for a processor family (like x86), so the compiler cannot make certain optimizations as they may not truly be optimizations on all processors. On the other hand, the CLR can make processor-specific optimizations during the JIT process. Does anyone know if Microsoft's (or Mono's) CLR actually performs processor-specific optimizations during the JIT process? If so, what kind of optimizations?

  • Setting current culture with threads in ASP.NET MVC

    - by mare
    Here's an example of SetCulture attribute which inside does something like this: public void OnActionExecuting(ActionExecutingContext filterContext) { string cultureCode = SetCurrentLanguage(filterContext); if (string.IsNullOrEmpty(cultureCode)) return; HttpContext.Current.Response.Cookies.Add( new HttpCookie("Culture", cultureCode) { HttpOnly = true, Expires = DateTime.Now.AddYears(100) } ); filterContext.HttpContext.Session["Culture"] = cultureCode; CultureInfo culture = new CultureInfo(cultureCode); System.Threading.Thread.CurrentThread.CurrentCulture = culture; System.Threading.Thread.CurrentThread.CurrentUICulture = culture; } I was wondering how does this affect a site with multiple users logged on and each one setting their own culture? What is the scope of a thread here with regards to the IIS worker process (w3wp) that the site is running in?
