Hi all,

I am trying to create a .csv file containing all the records returned from an odbc query but have so far ben unable to find any help on the matter.

I am using a standard odbc connection string etc. and executing the reader, but I don't know how to put the returned recordset into a .csv file.

Any help would be appreciated as this is the first time i've tried something like this and I'm still pretty new to .net

many thanks

Wow! This new thing called Google returned over 1 million records about Biztalk 2004! And since it's a Microsoft product, I'm sure msdn would not have a single article about it.

Better Buy a Book Related to Biztalk 2004 and read it.

Otherwise you could not understand.

As leckey said there are lot of links are there since that could not help you means better buy a book and start practicing the code.

Hi
Well basically I want to create some sort of rating system, usuing the ajax ratng control, below is an overview.

1. User rates page via rating control, selecting 1- 5 stars via clicking on them.

2. The value then tgets stored in a database

3. The top five pages with the highest numbers, a link gets displayed to the web page on the home page

http://www.codeproject.com do something, almost identical to this, but the one thing I dont understand is that the website will have around 1k of pages, therefore wont this be really slow? and how will I add the values up each time a page is rated?

Any help appreciated Smile | :)

Here is what you can do. Before you bind your grid (on page load, or whenever) store you dataTable in viewstate.

//In page load<br />
ViewState["yourDataTable"] = dt;<br />
<br />
<br />
 private void Addrow()<br />
{<br />
DataTable dt = (DataTable)ViewState["yourDataTable"];<br />
<br />
 int row = 0;<br />
<br />
            while (row < dt.Rows.Count)<br />
            {<br />
<br />
                TextBox txt = (TextBox)this.GridView.Items[row].FindControl("txt");<br />
dt.Rows[row]["txtValue"] = txt.Text;<br />
                <br />
<br />
                row += 1;<br />
            }<br />
<br />
 DataRow dr;<br />
dr = dt.NewRow();<br />
dt.Rows.Add(dr);<br />
<br />
<br />
 dg.DataSource = dt;<br />
dg.DataBind();

Problem with Health Monitoring (asp.net c# web app)

But_Im_a_Lady3-Jul-07 3:46

Hi,

I am new to the built in health monitoring functionality that comes built into the .net framework. I have followed a v.good video tutorial and I cant seem to get the last part of my code to work correctly...

I have configured my app to display an error page (when necessary) and this will write errors to the event viewer along with my custom error messages - this works fine.

My problem is when I try to write these same errors to sql. Here is my code from web config:-

<code><healthMonitoring>
<eventMappings>
<add name="InputValidationEvent"
type="WebEvents.InputValidationEvent, WebEvents"/>
</eventMappings>
<rules>
<add name="InputValidationToSql"
eventName="InputValidationEvent"
provider="SqlWebEventProvider"
profile="Critical"/>
</rules>
</healthMonitoring></code>

Here is the code in my WebEvents assembly class:-

<code>using System;
using System.Collections.Generic;
using System.Text;
using System.Web.Management;

namespace WebEvents
{
public class InputValidationEvent : WebFailureAuditEvent
{
public InputValidationEvent(object sender, string message)
: base(message, sender, WebEventCodes.WebExtendedBase + 1)
{}

public override void FormatCustomEventDetails(WebEventFormatter formatter)
{
base.FormatCustomEventDetails(formatter);
//formatter.AppendLine("This is where you can write custom message for the event logger!");
formatter.AppendLine(string.Format("Actual error exception raised by the PNWeb app : {0}",this.Message));
}

}

}</code>

What happens when an error occurs in my app:-

1) Errors are written to the event viewer - which is ok.
2) In App-Data (within my app) an ASPNETDB.MDF file appears, along with aspnetdb_log.LDF.

It doesn't write the error to the aspnet_webevents_events table which exists in my DB?

So what I need to know is: Why does it write the error to the DB within the App_data folder & NOT to the aspnet_webevent_events table in my database?

Hope I've explained in enough detail - its driving me nuts!

Thanks
Janet

Hi,

I've just worked on something very similar, here is my code:-

protected void _gridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
//find the link button for each row being databound
LinkButton linkButton = new LinkButton();
linkButton = (LinkButton)e.Row.FindControl("_name");

//Needed as the first row is for the headings!
if (linkButton != null)
{
//set its CommandArgument so that this can be referenced in the RowCommand Event of the GridView!
linkButton.CommandArgument = e.Row.RowIndex.ToString();
linkButton.CommandName = "ImageClicked";
}
}

protected void _gridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
if ((string)e.CommandName == "ImageClicked")
(
// Convert the row index stored in the CommandArgument property to an Integer.
int rowIndex = Convert.ToInt32(e.CommandArgument);

// Retrieve the row that contains the Linkbutton clicked from the Rows collection.
GridViewRow row = _gridView.Rows[rowIndex];

//use the findcontrol method
TextBox tb = new TextBox();
tb = (TextBox)e.Row.FindControl("_txtName");

)
}

Hope this helps
Janet

I find myself using "\n" when I'm writing to literals in javascript. I do this, because later when I view the source, to debug it, I get something that's intelligible rather than a single line. Ex:

<asp:literal runat="server" id="JSexample">

----- Later, in code-behind file ------

string jsString = "<script='text javascript'="">\n";
string jsString += "var something='This is something to say.';\n";
string jsString += "alert(something);\n";
string jsString += "\n";

JSexample.Text = jsString;

----- This way, I when debugging it shows up as: ----------

<script='text javascript'="">
var something='This is something to say.';
alert(something);

----- Instead of: ---------

<script='text javascript'="">var something='This is something to say.';alert(something);

This can make a big difference, when the javascript gets to be 50+ lines.
