How to develop Time Scheduler in asp.net web application?

February 10, 2014, 3:21 am

I am working on asp.net web application project. I want to develop a web page names as ApplyRulePage.aspx. User will apply rules (Rule has Start Time and End time) by uploading file. A Rule is defined for a period of time(From Start time to End time). lets say Rule is applied from a start time to end time(lets say from 14:56:59 March 1 2013 to 15:34:21 April 2013). User can apply multiple Rules if time span of Rules are mutually exclusive(means time is not clashing), So in this way We can apply any number of Rules for the User. But If lets say one Rule is applied and User wants to apply a new Rule and if time period of this new Rule is clashes with the Old Rule then We will give a message to the User that Old Rule will be deleted and new Rule will be applied and if time periods are not clashing it will so both Rule on Page.
 
So basic requirement is for a particular time period only one Rule should be applied.
 
My question here is how to implement this feature in asp.net. How well I can render page to the User so that it looks pretty good and For User it should be very easy to understand what exactly is happening on UI. If it could be achieved by javascript, jquery, ajax or some other programming, please let me know. If there is any link for a sample project or example please let me know. Sorry for such a stupid question actually I am learning asp.net by self and I have nobody to ask.

Hello Guys,
 
I have a simple asp.net page with an asp.net link button and asp.net content tag which point to a simple asp.net master page with an asp.net content place holder and a form tag. Here is the code of these two items:
 
Site.Master:
 
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="WebApplication1.SiteMaster"%> 
<htmlxmlns="http://www.w3.org/1999/xhtml"><head><title></title></head><body><formrunat="server"><asp:ContentPlaceHolderID="MainContent"runat="server"/></form></body></html>
 
Default.aspx:
 
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default"%> 
<asp:ContentID="BodyContent"runat="server"ContentPlaceHolderID="MainContent"><asp:LinkButtonID="LinkButton1"runat="server">LinkButton</asp:LinkButton></asp:Content>
 
From some reason when we run this simple web application on one server the id the link bhutton get is MainContent_LinkButton1
and when we run this application on another server the id the link button get is _ctl0_MainContent_LinkButton1
 
Doese someone have an idia why we get the prefix _ctl0_ in a specific server and in another server we don't get it?

I have the html5 side done but am looking for a resource or example of server side code that will upload the file to a SQL server. I know I'll using httpwebrequest.

I am trying to call the following method (api/test?name=user1) but I keep getting the 'unsuccessful' response. I have tried debugging the method and found it crashes on the 'mes' unsuccessful line. there is data retrieved from the database in the result variable but on the client-end it keeps showing 'unsuccessful' message.
 
public HttpResponseMessage GetName(string name)
        {
           User layer = new User();
 
            var result = layer.GetData(name);
 
            if (result.username != null)

                return Request.CreateErrorResponse(HttpStatusCode.NotFound, mes);

I am getting RSAProtection Error, please help me

Hi All,
Its killing my time I have been freaking with it, for some time I was a using a computer in which I didn't have this problem. Now my company gave me new computer I started getting this problem. Since two days I am just dieing to run my application. Without running my application what can I do? I just don't want any encryption and decryption on my machine, if they want to do it on the Server let them do it. If I want to say I don't want to play with any encryption or decryption where can I say that. Why the heck isn't simple to say that I don't want it. I have been researching, but every one is explaining how to encrypt or decrypt but no one is saying how just get out of it. I don't want it that's it.
 
I have an asp.net application, I don't want to encrypt or decrypt my web config file, but still I am getting the following error. How can I say that I want neither encryption nor decryption for my application on my machine.
I went into Machine.Config file and commented the RSA Encryption section as below
<!--<configProtectedData defaultProvider="RsaProtectedConfigurationProvider">
        <providers>
            <add name="RsaProtectedConfigurationProvider" type="System.Configuration.RsaProtectedConfigurationProvider,System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" description="Uses RsaCryptoServiceProvider to encrypt and decrypt" keyContainerName="NetFrameworkConfigurationKey" cspProviderName="" useMachineContainer="true" useOAEP="false"/>
            <add name="DataProtectionConfigurationProvider" type="System.Configuration.DpapiProtectedConfigurationProvider,System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" description="Uses CryptProtectData and CryptUnProtectData Windows APIs to encrypt and decrypt" useMachineProtection="true" keyEntropy=""/>
        </providers>
    </configProtectedData>-->
And my Web config doesn't have any encrypt or decrypt functionality defined as below.
<add key="SqlServerConnectionString" value="data source=xxxxSQLTEST\Prod;initial catalog=xxxx;password=xxxxxxxxxxx;persist security info=True;user id=xxxxxx"/>
    <add key="OracleConnectionString" value="data source=xxxx;password=incnpdev;user id=xxxxx"/>
    <add key="OleDbConnectionString" value="data source=(local);initial catalog=xxxxxx;password=xxxxxx;persist security info=True;user id=xxxxx"/>
Here is the following Error I am getting.

But if I keep the RSA section in the machine config file I am getting the following error. Why MS creates things like this. I don't even understand what is wrong. I the old machine I was not having this error, but when I got new machine to work on I am getting the following error. The same settings are there on every other developers machine they are not getting any error. This is making me nervous. Is my machine is incorrect what is wrong?
