Hi!
I'm trying to write a simple ASP.NET program that read data from wcf service and displays the data in GridView. WCF service works fine. It has simple interface:
[OperationContract]
List<EmployeeDetails> GetEmoloyeesDetails();
[OperationContract]
string ChangeEmployeeDetails(EmployeeDetails employeeInfo);
[OperationContract]
string AddEmployeeDetails(EmployeeDetails employeeInfo);
[OperationContract]
string DeleteEmployeeDetails(EmployeeDetails employeeInfo);
EmployeeDetails is set of string objects:
[DataContract]
public class EmployeeDetails
{
string employeeID = string.Empty;
string firstName = string.Empty;
string lastName = string.Empty;
string birthDate = string.Empty;
[DataMember]
public string EmployeeID
{
get { return employeeID; }
set { employeeID = value; }
}
[DataMember]
public string FirstName
{
get { return firstName; }
set { firstName = value; }
}
[DataMember]
public string LastName
{
get { return lastName; }
set { lastName = value; }
}
[DataMember]
public string BirthDate
{
get { return birthDate; }
set { birthDate = value; }
}
}
Now I create ASP.NET with GridView:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication2.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" Width = "550px" AutoGenerateColumns = "true" Font-Names = "Arial"
Font-Size = "11pt" AlternatingRowStyle-BackColor = "#C2D69B"
HeaderStyle-BackColor = "green" AllowPaging ="true" ShowFooter = "true" PageSize = "10" onrowediting="EditEmployee"
onrowcancelingedit="CancelEdit">
<Columns>
<asp:TemplateField ItemStyle-Width = "30px" HeaderText = "FirstName">
<ItemTemplate>
<asp:Label ID="lblFirstName" runat="server"
Text='<%# Eval("FirstName")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField EditText="Edit" ShoweditButton="true" />
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
This is simple test code (aspx.cs):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication2
{
public partial class WebForm1 : System.Web.UI.Page
{
ServiceReference1.StaffAccountingServiceClient proxy = new ServiceReference1.StaffAccountingServiceClient();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}
private void BindData()
{
GridView1.DataSource = proxy.GetEmoloyeesDetails();
GridView1.DataBind();
}
protected void EditEmployee(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();
}
protected void CancelEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
BindData();
}
}
}
I launch my ASP.NET client, and click on Edit link. And I see that dynamically created columns is in edit mode, but staticaly created columns is not 
I need to create a static table with the ability to edit. This is example what I want to do:
http://www.aspsnippets.com/Articles/Simple-Insert-Select-Edit-Update-and-Delete-in-ASPNet-GridView-control.aspx[^]
The difference is that I use WCF service to interact with data base.
Please, help me! What could be the problem?
Thanks!

Greetings experts,
I am not sure what forum to post this question.
So, naturally, I decided to post it on the forum I am a bit more familiar with but I can do this with script, asp, php whichever technology helps me accomplish this.
We would like to programmatically read the contents of logs in referenced on the subject line.
Particularly, we are interested in getting counts of site visits, pages visited, etc from the logs.
This task would have been easier if we had access to the codebehind of the web app built by a vendor.
Only the markup is accessible.
So far, we have been able to get this information from the logs manually and are looking for an opportunity to do this programmatically so our users can get the information they need more easily.
Your assistance is greatly appreciated.

Microsoft's Log Parser[^] works quite well.
Unfortunately, the site with the documentation[^] seems to be down at the moment. However, Log Parser Studio[^] gives you a GUI which should get you started.

Hello Richard,
*Always* great to hear from you.
I actually installed that software yesterday but had no idea how to connect it to a remote server.
I uninstalled it.
I am going to attempt to install it again and perhaps you can guide me on how to use it?
Thanks as always.

The fact that you are doing this remotely is a fairly important piece of information you should have included in your original question.
If you want to access the files remotely you'll need to do it via a UNC, which is the format you use to reference files over a network. If the files are at c:\inetpub\wwwroot\logs on a machine called "MyIIS" then you can access that folder from another machine using \\MyIIS\c$\inetpub\wwwroot\logs. This will need admin rights on the target machine. An alternative is to explicitly share the logs folder so you can control the access rights and use \\MyIIS\logs

As F-ES Sitecore said, you should be able to use a UNC path, so long as you have permission to access it.
There's a series on blog posts on SimpleTalk which might help:

Hi Richard and F-ES Sitecore,
It appears to be working now.
Thanks to you guys for the tips.
It feels really good to know that I can count on wonderful helpers like you guys.
Thank you

I am using Linq query to pull the latest 3 dates for a given record: EEGRP, EID.
However I am having issues when adding a new row into new table with non key columns:
result.Rows.Add .... item.EENAML.. etc.
Could you tell me what I am doing incorrect?
Dim data = myDataTable.AsEnumerable().GroupBy(Function(r) New With {Key .EEGRP = r.Field(Of String)("EEGRP"), Key .EESSN = r.Field(Of String)("EID")},
Function(key, rows) New With
{
Key .EEGRP = key.EEGRP,
Key .ESSN = key.EID,
.Dates = rows.Select(Function(r) r.Field(Of DateTime?)("DEIBCY") & ("DIIBYR") & ("D.DIIBMT") & ("DEIBDY")) _
.OrderByDescending(Function(d) d).Take(3).ToList()
})
Dim result As New DataTable
result = myDataTable.Clone()
For Each item In data
result.Rows.Add(item.EEGRP,item.EID, item.EENAML,item.EENAMF,item.EENAMM,item.EEADD1,item.EEADD2,,,, _

async and await method not suitable in heavy traffic website

Was there supposed to be a question hiding in there somewhere?

Not a question. However, if it were a question regarding what can a heavy traffic website handle the answer would still be "it depends." Availability and responsiveness are dependent on many different factors including the performance of IIS and then also of the sql db and the network. Many, many, different factors.

Don't post in multiple areas. It's considered rude.
As I told you in QA, your problem is that the sql is dynamic so the number of return columns cannot be determined ahead of time. Use something other than EF for this one.

I have Visual Studio 2010 Professional which should have the chart control in the toolbox. It is checked as being in the toolbox for both web forms and windows forms, but it is not showing. Is there some way to fix this? My projects are VB.

You could always try adding it anyway in to your page and see if it takes or if you get an error that might tell you what is happening.

Ryan,
Thank you. I resolved the issue thus: Loaded Visual Web Developer 2008 and added chart control to the toolbox. Opened VS 2010, unchecked chart controls from the Add Controls Dialog. Then added them back. Voila! Now the chart control appears in the vs 2010 toolbox.
Windows update kept trying to install update for the control, and failed for 5 days. Now the update should work. Hope this helps anyone who is experiencing a similar problem.

i have a problem using the auto complete with oracle, when i use @SearchText i don't now how fix it

Dim cmd As OracleCommand = New OracleCommand
cmd.CommandText = "select SITIOSEDENAME from INV_SITIOSEDE where " & _

conn.Open()
Dim customers As List(Of String) = New List(Of String)

conn.Close()
Return customers
End Function

You haven't told us what the problem is, but I'm guessing it's because you're using the wrong parameter prefix.
The OracleCommand class doesn't use @ as the parameter prefix; it uses : instead.
When using named parameters in an SQL statement called by an OracleCommand of CommandType.Text, you must precede the parameter name with a colon (:). However, in a stored procedure, or when referring to a named parameter elsewhere in your code (for example, when adding OracleParameter objects to the Parameters property), do not precede the named parameter with a colon.
cmd.CommandText = "select SITIOSEDENAME from INV_SITIOSEDE where SITIOSEDENAME like :SearchText || '%'"
cmd.Parameters.AddWithValue("SearchText", prefixText)

I've been looking around for some ideas or code for encrypting data like email addresses in c# for my MVC project.
I wrote some code in vb about 8 years back, wanted to beef it up this time, perhaps go 512K or higher. Cryptography is not one of my strong points. But I'm looking for suggestions on something rock solid.
[Edit]
The code I wrote is DES, guess I should go AES so I can use the Xeon CPU AES feature to make it faster, plus I'm now reading that DES is pretty unsecure.
I found this in code project. Not sure if I should adopt it or not. [Edit], I think I'll pass on this one and keep looking.

That is very similar to what I use and as far as I know, still very secure.
