Re: PROBLEM : Ttwice the dropdown function calling

27-Apr-08 21:05

Hard to say, it gets called once for me. Must be something to do with your code.

Have you called this function/event from anywhere else?which may trigger at the same time when combo SelectedIndexChanged event fired.

You have to define a template to edit only the one row, Idon't think you can easily change which row is edited. However, it's hard to say more, because

a/ there's tons of tutorials on this on the web, all of them work, your code must be broken
b/ you didn't post any code.

How to fine the length of array if it dosenot contain any value. [modified] (Solved)

Thanks I have solved the Problem.

Hello all,
In my application i have defined a array and dynamically i have created checkbox. Now i am finding the how meny checkbox user have checked by finding the length of array by using following code.

[code]
Dim qidArr() As String
Dim chkQues As CheckBox
Dim i As Integer
Dim sqid, lastid As String

For i = 0 To tableQuestion.Rows.Count - 1
chkQues = CType(tableQuestion.FindControl("chk" & i), CheckBox)
If chkQues.Checked = True Then
lid = CType(tableQuestion.FindControl("lblQid" & i), Label)
If ViewState("qid") <> Nothing Then
lastid = ViewState("qid")
sqid = lastid & "," & lid.Text
qidArr = sqid.Split(",")
Else
sqid = lid.Text
qidArr = sqid.Split(",")
End If
ViewState("qid") = sqid
ViewState("total") = qidArr
End If

Next

If qidArr.Length = 0 Then
Return 0
'ElseIf qidArr.Length = 0 Then
ElseIf qidArr.Length > 3 Then
Return 1
ElseIf qidArr.Length > 0 And qidArr.Length < 4 Then
Return 2
End If
[/code]

but the problem is that if user dosenot check any checkbox the it goes into exception [code]qidArr.Length = 0 [/code] after this statement.
Can anybody tell me how can i check length of array=0.

Thanks

People Laugh on me Because i am Different but i Laugh on them

Re: page.loadControl(string virtualpath)

Re: page.loadControl(string virtualpath)

You can use that User Control in the ASP.Net page itself.
like,

<%@ Register TagPrefix="UC1" TagName="IncludesAdminTop" Src="IncludesAdminTop.ascx" %>

Place this after the Page Directive.

Then

<UC1:IncludesAdminTop id="AdminTop" runat="server"></UC1:IncludesAdminTop>

Place this After or Before Body Tag

Implement CAPTCHA on LogInControl

27-Apr-08 19:47

To do that, you need to find out the end users time zone. A geolocation database, or asking hte user to tell you, seem the most likely solutions.

Ive been searching for any implementations of logincontrol with CAPTCHA
Ive founf a few, but none of them is what i have in mind
The "Best" i found (4guysfromrolla) always requires the user to input the captcha code

What i want is to only requiere captcha after 3 failed attemps (In a n mins period)
Using asp membership to lockout a user is not an option

Im have the following options and problems:

Option: I could count the failed attemps in the session, viewstate, etc
Problem: If the user closes the page, the count will be restarted
Problem: If it is an automated user, it can create a new session on each request

Option: Use IP to track retries
Problem: If it is an automated user, it can use proxies, and so can a normal user
Problem: Not all people has public IP, and if i use this approach, i would be requiring all users behind the blocked IP to imput the captcha control

Has anyone implemented something similar?
Please lt me know of any other ideas you might have

Thanks in advance

Hi,

I have a problem passing the value from parent to child. Can you please help? Thank you. My code:

protected void Message_To_Play_CheckedChanged(object sender, System.EventArgs e)
{
SqlConnection myConnection2;
myConnection2 = new SqlConnection("Data Source=oks\\sqlexpress;Initial Catalog=didb;User ID=sa;Password=AD");

SqlDataReader rdr = null;

try
{
myConnection2.Open();

SqlCommand myCommand2 = new SqlCommand ("SELECT TOP (1) RecNum FROM OUTDIAL_CAMPAIGN ORDER BY RecNum DESC", myConnection2);

rdr = myCommand2.ExecuteReader();

while (rdr.Read())
{

//HttpContext.Current.Response.Write("Your Record Number: " + rdr[0] + "");
// It write on the same page

HttpContext.Current.Response.Write("window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "'dependent=yes, resizable=yes, width=300, height=100');");
}
}
finally
{
// close the reader
if (rdr != null)
{
rdr.Close();
}

// Close the connection
if (myConnection2 != null)
{
myConnection2.Close();
}
}
// Done Querying the table to get the highest recnum.
