our coach gave me an excel file that contains information about Employers I want to put it under visual studio 2013 ultimate and I know how to do it

I have my ProfileCommon Class below
using System.Web.Profile;
public class ProfileCommon : ProfileBase
{
public string LastName
{
get
{
return (string)base["LastName"];
}
set
{
base["LastName"] = value;
this.Save();
}
}
public ProfileCommon GetProfile(string userName)
{
return (ProfileCommon)ProfileBase.Create(userName);
}
}
And the Profile section in the windows service app.config file is below
<profile enabled="true" defaultProvider="SqlProfileProvider" inherits="MyWindowsService.Code.ProfileCommon">
<providers>
<clear />
<add name="SqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="MyConnString" applicationName="Application1" />
</providers>
</profile>
And when i call sample code below
ProfileCommon prf1 = new ProfileCommon();
ProfileCommon prf = prf1.GetProfile("myWindowsLoginName");
string name = prf.LastName;
I get an error "Could not load type 'MyWindowsService.Code.ProfileCommon' from assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'."
What am i doing wrong in those sample code snippets? OR is this even the right way of using ProfileCommon in a windows service (.NET 4.0), is this wrong all together, is there a better way.
All i want is given a userName, i should get that user's Profile LastName or FirstName from LDAP.

devenv.exe wrote: inherits="MyWindowsService.Code.ProfileCommon"
According to the documentation[^], the inherits attribute is a "fully qualified type reference". That means you need to specify the assembly name as well.
devenv.exe wrote: All i want is given a userName, i should get that user's Profile LastName or FirstName from LDAP.
I don't see how the SqlProfileProvider is going to load anything from LDAP - it loads and stores the profile properties in SQL. You might have better luck using the System.DirectoryServices.AccountManagement assembly[^] to read this information.

Hai All,
As a part of my project I need to plot multiple series of data and need to show the color of each series in the Legend. But when I have added legend , it is diminishing the plotted area. and the plotted area views wiered. Could anyone give me a solution for this.
<pre lang="c#">
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
string sqlquery = "select " + dd_axisX.SelectedValue.ToString() + ", " + dd_axisY.SelectedValue.ToString() + " from retrospect where locid=" + ds.Tables[0].Rows[i]["locid"].ToString();
System.Data.DataSet ds_ValuesToPlot = new System.Data.DataSet();
da = new MySqlDataAdapter(sqlquery, con);
da.Fill(ds_ValuesToPlot, ds.Tables[0].Rows[i]["locname"].ToString());
double[] Xdata = ds_ValuesToPlot.Tables[0].AsEnumerable().Select(e1 => Convert.ToDouble(nullconvert(e1[dd_axisX.SelectedValue.ToString()]))).ToArray();
double[] Ydata = ds_ValuesToPlot.Tables[0].AsEnumerable().Select(e1 => Convert.ToDouble(nullconvert(e1[dd_axisY.SelectedValue.ToString()]))).ToArray();
chrt_ScatterPlot.Series.Add(ds.Tables[0].Rows[i]["locname"].ToString());
chrt_ScatterPlot.Series[ds.Tables[0].Rows[i]["locname"].ToString()].ChartArea = "ChartArea1";
chrt_ScatterPlot.Series[ds.Tables[0].Rows[i]["locname"].ToString()].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Point;
chrt_ScatterPlot.Series[ds.Tables[0].Rows[i]["locname"].ToString()].Points.DataBindXY(Xdata,Ydata);
chrt_ScatterPlot.DataBind();
System.Web.UI.DataVisualization.Charting.Legend lgd = new System.Web.UI.DataVisualization.Charting.Legend(ds.Tables[0].Rows[i]["locname"].ToString());
lgd.DockedToChartArea = "ChartArea1";
lgd.Docking = System.Web.UI.DataVisualization.Charting.Docking.Right;
lgd.MaximumAutoSize = 30;
lgd.LegendStyle = System.Web.UI.DataVisualization.Charting.LegendStyle.Row;
chrt_ScatterPlot.Legends.Add(lgd);
chrt_ScatterPlot.DataBind();
chrt_ScatterPlot.ChartAreas[0].Axes[0].Title = dd_axisX.SelectedValue.ToString();
chrt_ScatterPlot.ChartAreas[0].Axes[1].Title = dd_axisY.SelectedValue.ToString();
}
</pre>

A very simple example of Chart Control with Legend colors:
//design side:
<asp:chart id="yourchart" runat="server" Height="280px" Width="250px">
<titles>
<asp:Title ShadowOffset="3" Name="Title1" />
</titles>
<legends>
<asp:Legend Alignment="Center" Docking="Bottom" IsTextAutoFit="true" Name="Default" LegendStyle="Table" />
</legends>
<series>
<asp:Series Name="Default" /></series>
<chartareas>
<asp:ChartArea Name="ChartArea" BorderWidth="0" />
</chartareas>
</asp:chart>
yourchart.Series[0].XValueMember = "YourColumn";
yourchart.Series[0].YValueMembers = "YourColumn";
yourchart.Series["Default"].IsValueShownAsLabel = true;
yourchart.Series["Default"].ChartType = SeriesChartType.Pie;
yourchart.Series["Default"]["PieLabelStyle"] = "Disabled";
yourchart.ChartAreas["ChartArea"].Area3DStyle.Enable3D = false;
yourchart.Legends[0].Enabled = true;
LegendCellColumn LegendTextColumn = new LegendCellColumn();
LegendTextColumn.ColumnType = LegendCellColumnType.Text;
LegendTextColumn.Text = "#LEGENDTEXT";
yourchart.Legends["Default"].CellColumns.Add(LegendTextColumn);

I just my text in aspx page to be blink ...............
|
|

There was a <blink> tag - it's deprecated a long ago.
Also was a - non-standard - blink value for the text-decoration attribute - also deprecated.
Ah, and the - non-standard - blink() JavaScript function - deprecated.
Blinking text is very problematic - it's makes you site unfriendly for people with accessibility problems.
You can do some blinking text with JavaScript attached to some timer - or maybe use some animated gif. However for most people (designers and developers) it's not professional...

You can fake it using CSS3 animations:
<p>This is seriously <span class="blink">NASTY</span>!</p>
.blink
{
animation: blink 1s infinite alternate;
}
@keyframes blink
{
from
{
opacity: 1;
}
to
{
opacity: 0;
}
}

I am debugging an issue on my code caused by KB2894843. I know that MS has made EnableviewstateMAC = true in this KB update. The below piece of code is working fine in redirecting from page 1 to page 2 on click of submit except in the page 2 after redirecting from page 1, post back value is true. It is treating the page 2 as post back but ideally it should be true. I am not sure why it is treat it as post back. Appreciate any help on this.
Page 1 :
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Page1.aspx.vb" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

It's treated as a PostBack because you're posting a form to it which contains a field called __VIEWSTATE.
There are basically three ways to do what you want:
- Remove the
runat="server" from the <form> and <input> tags in page 1. You will no longer be able to access the controls from the code-behind.
<form>
<div>
<input type="submit" value="Click" onclick="f()" />
</div>
</form> - Replace the
<input> tag with an <asp:Button> tag, and set the PostBackUrl to "Page2.aspx".
<form id="form1" runat="server">
<div>
<asp:Button id="Submit1" runat="server" Text="Click" PostBackUrl="Page2.aspx" />
</div>
</form> - Since you're not passing anything in the request, change your script function to make a
GET request without using the form. You'll need to add return false; to the onclick attribute to stop the form from submitting.
<script type="text/javascript">
function f() {
location.assign("Page2.aspx");
}
</script>
<form id="form1" runat="server">
<div>
<input id="Submit1" type="submit" value="Click" onclick="f();return false;" runat="server" />
</div>
</form>

Thanks Richard. The same piece of code was working fine before the patch. It was returing it as "False" for post back in Page 2. I am just trying to understand what made this patch to broke the code which was working fine.

Dear all,
I am experiencing the following issue -- Invalid initializer member declarator -- error, on the following line of code.
return new ClaimRole() { query.uUsername = user.Username, query.uPassword == user.Password, user.role = "Trial" };
public UserDetail trial(string username, string password)
{
ClaimRole user = new ClaimRole();
var query = (from s in db.Subscriptions
join u in db.UserDetails on s.sUID equals u.uID
where s.sExpiryDate >= DateTime.Now &&
s.sPID.Value == 163 &&
u.uUsername == username &&
u.uPassword == password
select u).FirstOrDefault();
if (query != null)
{
return new ClaimRole() { query.uUsername = user.Username, query.uPassword == user.Password, user.role = "Trial" };
}
else
{
return null;
}
}
public class ClaimRole
{
public string Username { get; set; }
public string Password { get; set; }
public string role { get; set; }
}
User Detail is data model class from EF database.
My desired output, is to assign role property to the query.
Please advise. Many thanks.

Your object initializer syntax is messed up. Try:
return new ClaimRole { Username = query.uUsername, Password = query.uPassword, role = query.role };

Many thanks for your reply and help. That worked.  Apology for incorrect object's syntax.
Have a great evening.
