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

I suspect in this case, it's value is null.

i define a usercontrol and create it and put it in c:\ . then i use this code but i dont know the format of the path can any body help me?
protected Control userControl;
string userControlPath = @"c:/LitwareUserControl.ascx";
this.userControl = this.Page.LoadControl(userControlPath);
this.Controls.Add(this.userControl);
it gives this error: 'c:/LitwareUserControl.ascx' is not a valid virtual path.

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

Hi
In my project(C#.net) im getting the datetime from user and store it in the database. The given DateTime is the local Datetime.Our server is in USA.
I need to Convert the Given DateTime to Server Datetime before store it into the DB.

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

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

R u getting any Error? I think u have Syntax error in this line
HttpContext.Current.Response.Write("<script language="JavaScript">window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "'dependent=yes, resizable=yes, width=300, height=100');</script>");
Try this,
HttpContext.Current.Response.Write("<script language='JavaScript'>window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "','Test','dependent=yes,resizable=yes, width=300, height=100');</script>");

I got an error:
CS0103: The name 'Server' does not exist in the current context
HttpContext.Current.Response.Write("window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "'PopUpMessage','dependent=yes, resizable=yes, width=300, height=150');");
|
|
|
|
|
Try this
HttpContext.Current.Response.Write("<script language='JavaScript'>window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "','PopUpMessage','dependent=yes, resizable=yes, width=300, height=150');</script>");

It gives me this error:
Compiler Error Message: CS0103: The name 'Server' does not exist in the current context
HttpContext.Current.Response.Write("window.open('PopUpMessage.aspx?RecNum='" + Server.UrlEncode(this.rdr[0])+ "'Show Message','dependent=yes, resizable=yes, width=300, height=150');");

Hi,
I'm developing a treeview control in which by default if i click on all the parent nodes they are getting expanded. but my requirement is if i click on any of the parent node the remaining nodes are to be collapsed.
Is there any property in the design time to accomplish this, please let me know what is the best way to do this.
thanks,

hi,
i'd like to access to a menu control in my master page so i wrote the following code in the page that uses master page but it returns error
protected void Page_Load(object sender, EventArgs e)
{
Menu MenuCat = this.Form.Parent.FindControl("MenuCat");
...
Error message:
Error 434 Cannot implicitly convert type 'System.Web.UI.Control' to 'System.Web.UI.WebControls.Menu'. An explicit conversion exists (are you missing a cast?)
anyone knows what should i do?
|
|
|
|
|
i found it!!
i guess i should use this code:
protected void Page_Load(object sender, EventArgs e)
{
Menu MenuCat = (Menu)this.Form.Parent.FindControl("MenuCat");
Menu MenuSort = (Menu)this.Form.Parent.FindControl("MenuSort");
Menu MenuTypes = (Menu)this.Form.Parent.FindControl("MenuTypes");
Menu MenuLanguage = (Menu)this.Form.Parent.FindControl("MenuLanguage");
|

That works, but what I would do, is write a base page for all my pages, and in that base page, put a property that returns a strongly typed instance of my specific master page, as opposed to the Master property which returns the common base class.
At a minimum, I would store the names of those Menu controls as a resource, so you don't have to remember them and cannot mistype them, and I would check if FindControl returned null, so your site doesn't blow up if one of them is renamed or something.

how to use ajax in asp.net 2.0

Which control of AJAX you want to use?
I Love T-SQL
|
|

|

Depends what you mean. AJAX itself is just javascript. That's all it is, you don't need any special library or download, you can write AJAX code with notepad.
Given the tone of your question ( which indicates you're not willing to do any research on your own ), I assume you don't want to use AJAX at all, but just drag and drop some controls onto a form and have them do AJAX for you. In that case, you need to download the ASP.NET AJAX library, install it, and read the docs.
I recommend reading the article I link to in my sig for a start.
