  • Why will my AdRotator not display images? (Image paths are correct)

    - by KSwift87
    Hi. I'm writing a simple web application in C# and I've gotten to the part where I must add an AdRotator object and link four images to it. I have done this, but no matter what I do the images will not show up; only the alternate text. It makes no sense because the paths are correct. Supposedly AdRotator controls are really simple to use... But anyway below is my code. Search.aspx: <%@ Page Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Search.aspx.cs" Inherits="Module6.WebForm2" Title="Search" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> <form id="Search" runat="server"> This is the Search page! <div class="StartCalendar"> <asp:Calendar ID="Calendar1" runat="server" Caption="Start Date" TodayDayStyle-Font-Bold="true" TodayDayStyle-ForeColor="Crimson" SelectedDayStyle-BackColor="DarkCyan" /> </div> <div class="EndCalendar"> <asp:Calendar ID="Calendar2" runat="server" Caption="End Date" TodayDayStyle-Font-Bold="true" TodayDayStyle-ForeColor="Crimson" SelectedDayStyle-BackColor="DarkCyan" /> </div> <br /><br /> <div class="Search"> <asp:Button ID="btnSearch" runat="server" Text="Search" UseSubmitBehavior="true" /> </div><br /><br /> <div class="CenterAd"> <asp:AdRotator ID="AdRotator1" runat="server" Target="_blank" AdvertisementFile="~/Advertisements.xml" /> </div> <br /><br /> <div class="Results"> <asp:GridView ID="gvResults" runat="server" /> </div> </form> </asp:Content> Advertisements.xml: <?xml version="1.0" encoding="utf-8" ?> <Advertisements> <Ad> <ImageURL>~/images/colts.jpg</ImageURL> <AlternateText>Colts Image</AlternateText> </Ad> <Ad> <ImageURL>~/images/conseco.gif</ImageURL> <AlternateText>Conseco Image</AlternateText> </Ad> <Ad> <ImageURL>~/images/IndianapolisIndians.png</ImageURL> <AlternateText>Indianapolis Indians Image</AlternateText> </Ad> <Ad> <ImageURL>~/images/pacers.gif</ImageURL> <AlternateText>Pacers Image</AlternateText> </Ad> </Advertisements> Any and all help is GREATLY appreciated.

  • Dealing with SerializationExceptions in C#

    I get a SerializationException: (...) is not marked as serializable. error in the following code: [Serializable] public class Wind { public MyText text; public Size MSize; public Point MLocation; public int MNumber; /.../ } [Serializable] public class MyText { public string MString; public Font MFont; public StringFormat StrFormat; public float MySize; public Color FColor, SColor, TColor; public bool IsRequest; public decimal MWide; /.../ } and the List to be serialized: List<Wind> MyList = new List<Wind>(); Code Snippet: FileStream FS = new FileStream(AppDomain.CurrentDomain.BaseDirectory + "Sticks.dat", FileMode.Create); BinaryFormatter BF = new BinaryFormatter(); BF.Serialize(FS, MyList); FS.Close(); throws an Exception: System.Runtime.Serialization.SerializationException was unhandled Message="Type 'System.Drawing.StringFormat' in Assembly 'System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable."

  • Workflow Service host not publishing Metadata.

    - by jlafay
    Still hacking away with extreme persistence at WF services hosted outside of IIS. I'm now having issues with my WF service publishing metadata. Can someone take a look at my code and see what step I'm missing? The few tutorials that I've stumbled across for my scenario make it look so easy, and I know it is. I'm just missing something ridiculously simple. Here's my current trial code: const string serviceUri = "http://localhost:9009/Subscribe"; WorkflowServiceHost host = new WorkflowServiceHost( new Subscribe(), new Uri(serviceUri) ); SubscriberSvcHost.AddDefaultEndpoints( ); SubscriberSvcHost.Open(); Subscribe() is an activity that is coded in an xaml file and contains simple receive and sendreply activities to test out my hosted workflow service. It is NOT a xamlx (WF service) file. Seems like this should be simple enough to work but when I start the application and the service fires I get this message in my browser when navigating to the URI: "Metadata publishing for this service is currently disabled." Shouldn't adding the default endpoints provide enough metadata and description to satisfy the service init and then go into its wait for message state?

  • Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key"

    - by Michael Rosario
    Hello world. Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme? Problem facts: I am using Oracle XE. I have implemented the following table and trigger: CREATE TABLE "USERS" ( "ID" NUMBER(38,0), "USER_NAME" VARCHAR2(50), "PASSWORD" VARCHAR2(50), "EMAIL" VARCHAR2(100), CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE ) / CREATE OR REPLACE TRIGGER "BI_USERS" before insert on "USERS" for each row begin select "USERS_SEQ".nextval into :NEW.ID from dual; end; / ALTER TRIGGER "BI_USERS" ENABLE / MyGeneration / Doodads created the following stored proc... CREATE OR REPLACE PROCEDURE "XXX"."PI_USERS" ( p_ID IN USERS.ID%type, p_USER_NAME IN USERS.USER_NAME%type, p_PASSWORD IN USERS.PASSWORD%type, p_EMAIL IN USERS.EMAIL%type ) IS BEGIN INSERT INTO USERS ( ID, USER_NAME, PASSWORD, EMAIL ) VALUES ( p_ID, p_USER_NAME, p_PASSWORD, p_EMAIL ); END PI_USERS; The sequence and trigger combination is working fine. The BusinessEntity class in C# does not receive the new ID. Any recommended ways to allow the calling code receive the new record ID?

  • Please help! request compression

    - by Naor
    Hi, I wrote an IHttpModule that compress my respone using gzip (I return a lot of data) in order to reduce response size. It is working great as long as the web service doesn't throws an exception. In case exception is thrown, the exception gzipped but the Content-encoding header is disappear and the client doesn't know to read the exception. How can I solve this? Why the header is missing? I need to get the exception in the client. Here is the module: public class JsonCompressionModule : IHttpModule { public JsonCompressionModule() { } public void Dispose() { } public void Init(HttpApplication app) { app.BeginRequest += new EventHandler(Compress); } private void Compress(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpRequest request = app.Request; HttpResponse response = app.Response; try { //Ajax Web Service request is always starts with application/json if (request.ContentType.ToLower(CultureInfo.InvariantCulture).StartsWith("application/json")) { //User may be using an older version of IE which does not support compression, so skip those if (!((request.Browser.IsBrowser("IE")) && (request.Browser.MajorVersion <= 6))) { string acceptEncoding = request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(acceptEncoding)) { acceptEncoding = acceptEncoding.ToLower(CultureInfo.InvariantCulture); if (acceptEncoding.Contains("gzip")) { response.AddHeader("Content-encoding", "gzip"); response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); } else if (acceptEncoding.Contains("deflate")) { response.AddHeader("Content-encoding", "deflate"); response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress); } } } } } catch (Exception ex) { int i = 4; } } } Here is the web service: [WebMethod] public void DoSomething() { throw new Exception("This message get currupted on the client because the client doesn't know it gzipped."); } I appriciate any help. Thanks!

  • Grouping problem with postback in SPGridview

    - by Abhishek Rao
    I have a SPGridView with a custom CheckBox Template in it. To access the value of the checkbox I have created the SPGridView in Page_Init method. It was working fine. I also have grouping in the grid. It was working fine till I made any postback in the page. To overcome that I created my own custom GridView and overrided the LoadControlState event. Now the problem is when I use this Custom Grid in my page the LoadControlState event occurs after the Init event and hence the grid doesnt render on the page. When i keep it in Page_Load it works fine but my custom checkbox template creates a problem then. How do I get both the custom Checkbox Template and grouping with postback in the SPGridview working properly??? Please help as this is really getting me stuck.........

  • Why can’t GridView extract child control’s values directly?

    - by SourceC
    Hello using Bind in a GridView control template enables the control to extract values from child controls in the template and pass them to the data source control. The data source control in turn performs the appropriate command for the database. For this reason, the Bind function is used inside the EditItemTemplate or InsertItemTemplate of a data-bound control. Why is Bind() needed to extract values and pass them to GridView. Why isn’t GridView able to extract child control’s values directly? thanx

  • Writing Android apps in C#

    - by JamesBrownIsDead
    I'm a C# programmer and want to write an Android app. I'm a stubborn curmudgeon and refuse to write Java ever again (after switching to C# six years ago). Besides Mono and MonoDroid (and writing Java), are there any options for me? Or should I just feel foolish for refusing to returning to my Java roots? (Please refrain from Java-related vs. C# discussion. I was being rhetorical when I asked about returning to me Java roots.)

  • Can not parse table information from html document.

    - by Harikrishna
    I am parsing many html documents.I am using html agility pack And I want to parse the tabular information from each document. And there may be any number of tables in each document.But I want to extract only one table from each document which has column header name NAME,PHONE NO,ADDRESS.And this table can be anywhere in the document,like in the document there is ten tables and from ten table there is one table which has many nested tables and from nested table there may be a table what I want to extract means table can be anywhere in the document and I want to find that table from the document by column header name.If I got that table then I want to then extract the information from that table. Now I can find the table which has column header NAME,PHONE NO,ADDRESS and also can extract the information from that.I am doing for that is, first I find the all tables in a document by foreach (var table in doc.DocumentNode.Descendants("table")) then for each table got I find the row for each table like, var rows = table.Descendants("tr"); and then for each row I am checking that row has that header name NAME,ADDRESS,PHONENO and if it is then I skip that row and extract all information after that row foreach (var row in rows.Skip(rowNo)) { var data = new List<string>(); foreach (var column in row.Descendants("td")) { data.Add(properText); } } Such that I am extracting all information from almost many document. But now problem is sometimes what happened that in some document I can not parse the information.Like a document in which there are like 10 tables and from these 10 tables 1 table is like there are many nested tables in that table. And from these nested tables I want to find the table which tabel has column header like NAME,ADDRESS,PHONE NO.So if table may be anywhere in the document even in the nested tables or anywhere it can be find through column header name.So I can parse the information from that table and skip the outer tabular information from that table.

  • Opened SerialPort crashes C# application

    - by Stefan Teitge
    The computer is connected to measuring device via a physical COM1. I have simple form where I open a serial port, tell the device that I'm alive and occasionally the device sends data. (every some minutes) Thread _readThread = new Thread(Read); SerialPort _serialPort = new SerialPort("COM1", 9600); _serialPort.Parity = Parity.None; _serialPort.DataBits = 8; _serialPort.StopBits = StopBits.One; _serialPort.Handshake = Handshake.None; _serialPort.DtrEnable = true; _serialPort.Open(); _readThread.Start(); _serialPort.Write("#listening"); The read function (which works): public void Read() { string message = _serialPort.ReadLine(); } After approximately one minute the application crashes (even while debugging). It reports an ObjectDisposedException (for the underlying stream?). The message tells that the SafeHandle was closed. Stack strace is below: at Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(SafeFileHandle hFile, NativeOverlapped lpOverlapped, Int32& lpNumberOfBytesTransferred, Boolean bWait) at System.IO.Ports.SerialStream.EventLoopRunner.WaitForCommEvent() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()* Any ideas? The problem is reported widely but usually involve the device beeing physically detached from the PC.

  • Removing an Entity from an EntitySet during Iteration...

    - by Gregorius
    I've got this code... seems nice and elegant, but apparently the framework don't like it when i mess with a collection while iterating through it: foreach (KitGroup kg in ProductToTransfer.KitGroups) { // Remove kit groups that have been excluded by the user if (inKitGroupExclusions != null && inKitGroupExclusions.Contains(kg.KitGroupID)) ProductToTransfer.KitGroups.Remove(kg); else { // Loop through the kit items and do other stuff //... } } The error it throws when it iterates to the 2nd object in the collection is: "EntitySet was modified during enumeration" I know i could create a new collection of KitGroup objects (or even just IDs) that i want to remove, and then another loop afterwards to loop through these, and remove them from the collection, but this just seems like unnecessary extra code... can anybody suggest a more elegant way of achieving the same thing? Cheers Greg

  • DataSource Control for List<T>

    - by diamandiev
    I know all the data source controls like LinqDataSource, ObjectDataSource etc. They are cool but they are intended to be used in conjunction with a database. I actually need a simple data source control that can work with a plain old List (That supports delete, update, select, insert ofcourse). I was thinking of using the objectdatasource but the select, update... methods are not present in the List. So is there such a control or do i have to roll my own? Should i inherit from the objectdatasource?

    I have created a custom cofirm message box control and I created an event like this- [Category("Action")] [Description("Raised when the user clicks the button(ok)")] public event EventHandler Submit; protected virtual void OnSubmit(EventArgs e) { if (Submit != null) Submit(this, e); } The Event OnSubmit occurs when user click the OK button on the Confrim Box. void IPostBackEventHandler.RaisePostBackEvent(string eventArgument) { OnSubmit(e); } Now I am adding this OnSubmit Event Dynamically like this- In aspx- <my:ConfirmMessageBox ID="cfmTest" runat="server" ></my:ConfirmMessageBox> <asp:Button ID="btnCallMsg" runat="server" onclick="btnCallMsg_Click" /> <asp:TextBox ID="txtResult" runat="server" ></asp:TextBox> In cs- protected void btnCallMsg_Click(object sender, EventArgs e) { cfmTest.Submit += cfmTest_Submit;//Dynamically Add Event cfmTest.ShowConfirm("Are you sure to Save Data?"); //Show Confirm Message using Custom Control Message Box } protected void cfmTest_Submit(object sender, EventArgs e) { txtResult.Text = "User Confirmed";//I set the text to "User Confrimed" but it's not displayed txtResult.Focus();//I focus the textbox but I got Error } The Error I got is- System.InvalidOperationException was unhandled by user code Message="SetFocus can only be called before and during PreRender."

Can anybody help me to add event dynamically to custom control? Thanks.

  • Using foreach loop.

    - by Harikrishna
    I break the code of the for loop without using break like I have for loop given below.And when i is 1 or 2 or 3 or any else but if condition is true then loop will be terminated because i will be 5 if the condition is true.And so NO need of break is needed there.Beacause I do not want to use break.I have done like this here.It works. bool myCondition=false; for(int i=0;i<5;i++) { if(myCondition) { i=5; } } But now I want to use foreach loop and in this loop when some condition is true then I want to break the foreach loop code.So what should I do here for breaking the foreach loop code without using break ? Like in the above for loop I have initialize i to 5 when condition is true.In the foreach loop anything like that to do to avoid break.

  • Open protected web page passing in credentials programmatically

    - by beaudetious
    I have code examples from some of my previous work that help me to post form values to a web page (login credentials) and retrieve the text from that page. Now I want to pass in form values (login credentials again) but actually open that web page in a browser given those credentials. How do I do that? I'm not doing anything nefarious. In our CRM app (home-grown as it is), I want to create a link button that opens our web site's protected products page given the user's credentials (based on the user's login credentials). Normally, I'd copy the user's credentials in our login page which then takes me to the products page. I'm trying to do this now by just clicking a link button. Any suggestions?

  • Databinding gives "System.Data.DataRowView" instead of actual values

What happened? How can I fix it? Thank you very much.
