CAN ANYONE HELP ME INTEGRATE MULTIPLE UPLOADS IN THE ABOVE MENTIONED FRAMEWORK :) ?
Perhaps a Flash-based upload tool would work better. Many sites that support multiple uploads on a single page are moving to this kind of solution.
Here are a couple that a Google search unearthed:
Multiple File Upload With Progress Bar Using Flash and ASP.NET
MultiPowUpload
FYI, these pages are classic ASP and unrelated to the more recently introduced ASP.NET technology.
I don't know how to fix your problem, but a long, long time ago, I've used the commercially available SoftArtisans FileUp component to allow reliable multi-file uploads in classic ASP.
Did you try using multiple <input type="file"> 's?
EDIT:
What you might try also then, is dynamically creating an IFRAME with the file input field in it and submit that form, holding the file in a temporary location on the server and somehow indicating to the user that they have uploaded one of the files.

Try not to duplicate HTML when it is unnecessary and instead workout your logic and apply the result afterwards. Also, make sure that the code is inside ASP preprocessor tags <% %> or it will not be treated as code.
ASP file with 2 scripts does not load second script
I have as ASP page, this page reads a xml file and shows the information inside a table.
I need to create a second script just like the first one to read a second xml file and display the info in another table.

Ok, i have found my mistake, in the line if activo="S" then of the second script, it should be if activocult="S" then. thanks for your time
Putting variable into html text box
I have a script that pulls data from the SQL database, stores the data into variables. Now I need to take that data and put them into HTML forms (textboxes?) so they can edit them, and then I will run a UPDATE query to update. ' Create a DataReader and execute the command objDR = objCmd.ExecuteReader While objDR.Read() sale_id = objDR(0) cust_id = objDR(1) agent_id = objDR(2) saledate = objDR(3) actualamount = objDR(4) contractid = objDR(5) homeid = objDR(6) End While strSuccess.Text = "<h2>Sale ID #" & agent_id & " and " & actualamount & "</h2>" strSuccess.Visible = "True" ' Close all objects objDR.Close objCmd.Dispose objDBConn.Close End Sub </script> <title>CUSTOMERS table</title> </head> <body> <center> <h2>Oracle sales table contents</h2> <asp:label id="strSuccess" runat="server" /> Sale Amount: <input TYPE="text" NAME="saledate"> </center> </body> </html> I want to take 'saledate' and put it into the sale amount form.
Set your value in vb and add a asp:TextBox control instead of html control in your Sale Amount form. You can do it by change your code in this way： ' Create a DataReader and execute the command objDR = objCmd.ExecuteReader While objDR.Read() sale_id = objDR(0) cust_id = objDR(1) agent_id = objDR(2) saledate = objDR(3) actualamount = objDR(4) contractid = objDR(5) homeid = objDR(6) End While strSuccess.Text = "<h2>Sale ID #" & agent_id & " and " & actualamount & "</h2>" strSuccess.Visible = "True" txtsaledate.Text = saledate 'Set value here ' Close all objects objDR.Close objCmd.Dispose objDBConn.Close End Sub </script> <title>CUSTOMERS table</title> </head> <body> <form id="frm" runat="server"> <center> <h2>Oracle sales table contents</h2> <asp:label id="strSuccess" runat="server" /> Sale Amount: <asp:TextBox ID="txtsaledate" runat="server"></asp:TextBox> </center> </form> </body> </html>
How to loop through a table to see if the checkbox are checked
I'm trying to loop through a table to see if a check box is checked. On button click SendCheckEmail is called. I'm getting an error EmailForm is not declared and also I'm unsure of how to loop through the table to process each checkbox that is checked.
Sub Page_Load
If Request.QueryString("show") <> "" then
dim Sr as StreamReader = New StreamReader("d:\netdrvs\prs\emaillist\" & Request.QueryString("show"),FileMode.Open)
output="<table id=EmailForm border=1 padding=4 >" & VBCR
output+="<tr><td>Customer Code</td><td>Email</td><td>Invoice Number</td><td>Regarding</td><td> <input type=checkbox name=chkHeader id=chkHeader></td></tr>"
While Not SR.EndOfStream
dim Temp(3) as String
Temp = Split(SR.ReadLine(),vbTab)
dim temp2(3) as String
Temp2 = Split(Temp(0),"_")
output += "<tr>" & VBCR
output += "<td>" & Temp2(1) & "</td>" & VBCR
output += "<td>" & Temp(1) & "</td>" & VBCR
output += "<td>" & Temp2(0) & "</td>" & VBCR
output += "<td>" & Temp(2) & "</td>" & VBCR
output += "<td> <input type=checkbox name=chkRow id=chkRow> </td>" & VBCR
output += "</tr>"& VBCR
End While
output+="</table>" & VBCR
SR.Close()
ProcessChk.Visible = True
end if
End Sub
Sub SendCheckEmail (sender As Object, e As System.EventArgs)
Dim item
For each item in EmailForm
'loop through each row
NEXT
End Sub

set runat="server" to EmailForm
and then
IN C#
foreach (var item in tbl.Rows)
{
HtmlTableRow row = (HtmlTableRow)item;
foreach (var item1 in row.Controls)
{
HtmlTableCell cell = (HtmlTableCell)item1;
}
}
In VB.NET
Dim rowitem
Dim cellitem
For Each rowitem In tbl.Rows
HtmlTableRow row = (HtmlTableRow)rowitem;
For Each cellitem In tbl.Rows
HtmlTableCell cell = (HtmlTableCell)cellitem;
// cell items
next
next
// can directly access checkbox if it is set to runat='server'
EmailForm is not a a server control, so you cannot access it in CodeBehind.
You could try using a repeater or a table control that you bind to the file contents.
Otherwise you could add the email address as value attribute in the input tag.
output += " " & VBCR
Then you will receive a comma separated list of email addresses by accessing Request("chkRow")
