Why not putting it into session ? Smile | :)

Set Session Like :

Session["LoginID"]= txtLoginId.Text

Retrieve it in different form

string strLoginID=Session["LoginID"].ToString();

Hope this will help you Smile | :)

Using large data buffers

Hi.

I'm working on a web application developed using C# that displays an image sent by an windows forms application. The image is 1024*768, 1 byte depth, no compressed. So it uses 786432 bytes. To hold it I have declared a byte[] of this size. I'm new with ASP.NET and I don't know if I'm doing something wrong. I can imagine that if the buffer is allocated on server side, several instances of the web application can suppose a big trouble. Or I'm wrong and the buffer is allocated on client side? Which is the best way of sending the images? Binary streams?

Thanks in advance, Xavier

Dear all,
Am sending this msg regarding asp.net 1.1 email usage.
My code for sending email is below.
The problem it is reaching my inetpub/mailroot/queue instead of actual mail id.
I have seen all my smtp server settings which are using port 25 and localhost as smtpserver.No error nothing.
Can anybody resolve using asp.net 1.1 not with 2.0.
I had the solution for 2.0

Code is on button click event

Dim cdoconfig, cdomessage, sch
sch = "http://schemas.microsoft.com/cdo/configuration/"
cdoconfig = Server.CreateObject("CDO.Configuration")
cdoconfig.Fields.Item(sch & "sendusing") = 2
cdoconfig.Fields.Item(sch & "smtpserver") = "localhost"
cdoconfig.Fields.Update()
cdomessage = CreateObject("CDO.Message")
With cdoMessage
.Configuration = cdoconfig
.From = _txtFrom.Text
.To = _txtTo.Text
.Subject = _txtSubject.Text
.TextBody = _txtMessage.Text
.Send()
End With
cdomessage = Nothing
cdoconfig = Nothing

I tried maximum trails still am not with the right solution.Can nay body tell me if u r free.

There could be many reason in behind.

Please check Port is not blocked by firewall.

You can try one thing :

1. Go To > IIS > Default SMTP Server > Properties
2. Go to Delivery Tab
3. Set First, Second, Third, Subsequent Retry Interval To 1

Hope this will resolve your Issue Smile | :)

I am not sure why are you using CDO to do this in .Net.
In .Net 1.1, you should rather use the System.Web.Mail.MailMessage do send email.

1.)You did not even care to put your question properly.
2.)This is not a ASP question.

Hi,

Javascript:

function Fun(event)
{
var obj = event.srcElement || event.target ;
var seltreeNode = obj;
textbox.value = seltreeNode.innerHTML;
}

CodeBehind:

treeview.attribure.add("onclick","Fun(event)")

So the Selected Node is copied to the Textbox sucessfully. But if the textbox is readonly=true or Enabled=false i cannot copy the selected node to the TExtbox. How to REsolve this problem.
I think now u will get clarified...

Thanks,
kannak....

Shouldn't you do:

document.getElementById("textbox").value = seltreeNode.innerHTML;

This is your Server Side Control I Guess.
So first you need to read the Client ID and then read the Value From It.

var textBoxID="<%=textBox.ClientID%>";
var textBoxValue=document.getElementById(textBoxID);

Note : If the Textbox is server side control and you have make it ReadOnly, It will not send value to server while Postback. Smile | :)

Hope this will help you Smile | :)
