Hello,
I have been stuck up with one issue, It would be very helpful if any one can help me on this.
I have to track the visitors coming to my website. I managed this by writing a HTTPModule and storing the details in a SQL Server database. When user visits each page, it will be inserted into database table. But when traffic increases to the site, this method became very slow. So I thought of storing the details in a flat file instead of SQL Server table. My doubts are
1 - How can I communicate with flat files in ASP.NET. Is it by using StreamReader and StreamWriter ?
2 - Is XML Files can be called as Flat Files ?
3 - When multiple users are browsing website at same time, is it possible to update the file contents ? (Because file may be in use)
4 - Will this method can boost the performance ?
Thanks,
|

Why not just enable IIS Logs and you can parse those as needed?
I don't think moving to a flat file is going to improve performance as much as you think. As you pointed out, you will probably run into file access constraints.

Yes that's what I am doing now. But that is having some drawbacks like it will log all the files including images. So it's tough to fetch required information from the whole list.
Moreover I need to track how much time user stayed on each page. So I think I need another alternate solution instead of IIS log.

Hi All, I've got some weird validation problems.
I've been using <asp:RequiredFieldValidator> in my web page, and up till now they've been working perfectly. However I recently migrated the webpage from Visual Studio 2003 to Visual Studio 2005. The validators are no longer working.
Now I really like these validators, and I don't want to be foreced to use JavaScript or Server side validation.
Anybody have any clue as to what could be going on with the validators and how to fix them?

What error are you getting?
There is the RequiredFieldValidator in ASP.NET 2.0 too.
The validator from 1.1 "RequiredFiedlValidator 1.1" and RequiredFiedlValidator 2.0 looks the same.. so, there should be no problem..
Thanks and Regards,

I'm not getting any errors.
It's just immediately submitting the page.
This is how the validators are set up:
<asp:RequiredFieldValidator ID="Requiredfieldvalidator12" Width="30%" ControlToValidate="txt_ConsoleSerial" Display="Static" InitialValue="" runat="server">*</asp:RequiredFieldValidator>

Hi!..
I'm looking for an application / framework that let me do something like this:
http://www.ideastorm.com/
http://ideas.salesforce.com/
I've heard of crispy ideas, the company that did that development, but they're not selling their product at this moment.
This tool is great for software improvements
you can post "ideas"
you can vote for ideas and discuss about them, and them deliver them as a part of your ongoing software development.
Do you know of some commercial / non-commercial product that I could get in order to do this?
Some idea?
Thanks a lot!..

The session will not end even though the browser is closed..You can put the code in the global.asa session_end event.. But you need to remember that this will be fired only if the session is stored in InProc and not if on ASP.Net state service or SqlServer.
Check your Web.config for the entry
<sessionstate
mode="<b>StateServer</b>" <b="">This should be InProc
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="60"
/>

I'm creating a customer "comments", multiline textbox and it works fine however when I store these comments in the database, they don't retain any of the formatting the user performed within their comments, such as line breaks.
For example, the following comment...:
"Hello,
How are you?"
...would be stored in the database like this:
"Hello, How are you?"
How can I correct this?
Thanks.

The line break is there - if you load it back into a multi-line text box you'll see it just the same as entered in the first place - but to displayt it on a web-page you need to replace all the line breaks with <br> tags... in VB this would be:
supposing your databse field is returned to a string s:
s.Replace(vbCrLf, "<br>")
Can't help you with the C# equivalent, but the carriage-return line-feed characters are Chr(13) adn Chr(10) respectively...

Hi,
my question is this:
Is it possible to know if my site is running on IIS or on Web Development Server at runtime from code behind?
The only solution that I found is to check the process name, but...
Thanks

You can check the Response.headers to see if it sis running on IIS or not.and of course its version as well.
In ASP.Net this is available through Response.Headers variable

var gridViewCtlId = '<%=gridview1.ClientID%>';
var gridViewCtl = null;
var curSelRow = null;
var curRowIdx = -1;
function getGridViewControl()
{
if (null == gridViewCtl)
{
gridViewCtl = document.getElementById(gridViewCtlId);
}
}
function onGridViewRowSelected(rowIdx)
{
var selRow = getSelectedRow(rowIdx);
if (null != selRow)
{
curSelRow = selRow;
var cellValue = getCellValue(rowIdx, 0);
alert(cellValue);
}
}
function getSelectedRow(rowIdx)
{
return getGridRow(rowIdx);
}
function getGridRow(rowIdx)
{
getGridViewControl();
if (null != gridViewCtl)
{
return gridViewCtl.rows[rowIdx];
}
return null;
}
function getGridColumn(rowIdx, colIdx)
{
var gridRow = getGridRow(rowIdx);
if (null != gridRow)
{
return gridRow.cells[colIdx];
}
return null;
}
function getCellValue(rowIdx, colIdx)
{
var gridCell = getGridColumn(rowIdx, colIdx);
if (null != gridCell)
{
alert(gridViewCtlId)
return gridCell.innerText;
}
return null;
}
I i call it as:
For Each row As GridViewRow In GridView1.Rows
CType(row.FindControl("Textbox1"), TextBox).Attributes("onclick") = "javascript: return getCellValue(0,1)"
it works...
But how to pass dynamic value in place of 0 and 1
<div class="ForumSig">sanjay kumar samantaray</div>

What dynamic values do you want to pass instead of 0 and 1? Please be more specific when phrasing a question.
If the first argument to your javascript function needs to change with each iteration of the loop, get the index of the current row by referencing the RowIndex property of your row object and insert it into your attribute string. For instance:
CType(row.FindControl("Textbox1"), TextBox).Attributes("onclick") = "javascript: return getCellValue(" + row.RowIndex.ToString() + ",1)"
Do something similar if you need to change the column index dynamically.

Have a look at the HTML generated by your page. Are the javascript event handlers being generated correctly?

Hi,
I want to retreive the user id of the person who visits the page created by me. Till now I was using the System.Identity.Name method to retreive user id of the person. But this gives me the user id of the person who is logged in the system.It didnt give me any worries since I was using VS in my machine. Now when I try to run the page from IE of other machine it is giving error which says Input string was not in a correct format. I am including the codeline where it is giving error.
txtid.Text = Right(User.Identity.Name, 6)
Dim sconnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Mypath\DW\DW.mdb;User ID=Admin; Password="
Dim dbcon As New OleDbConnection(sconnection)
Dim myCommand = New OleDbCommand("Select associate_id from dwbi", dbcon)
Dim dr As OleDbDataReader
dbcon.Open()
dr = myCommand.ExecuteReader()
While (dr.Read())
MsgBox("textid.text")
If dr("associate_id") = txtid.Text Then 'This is where error is pointing
Response.Redirect("Update.aspx")
End If
End While
dr.Close()
dbcon.Close()
End If
End Sub
It is gving the error which says "Input string was not in a correct format"

Iterate through the child nodes of the selected node.
Paul

i just used a sample code
var selNode = tree.getTreeNode(tree.selectedNodeIndex);
for(var nodeCount = 0; nodeCount < selNode.getChildren().length; nodeCount++)
{
var chldNode = selNode.getChildren(String(nodeCount));
alert(chldNode[nodeCount].getAttribute('ID'));
alert(chldNode[nodeCount].getAttribute('Text'));
}
in this, alert(chldNode[nodeCount].getAttribute('ID')); is working but alert(chldNode[nodeCount].getAttribute('Text')); is not working. is there any error?..

The attribute names are case-sensitive. Try 'text' instead of 'Text'.

We don`t do spoon feeding here. Why don`t you first read some books.Don`t try to just copy the code, understanding is all that matters.
When you fail to plan, you are planning to fail.
