if you have datset which contains the data from database then try this code
for (int index = 0; index < ds.Tables[0].Rows.Count; index++)
{
object[] array = ds.Tables[0].Rows[index].ItemArray;
string str = array.GetValue(0).ToString();
DropDownList1.Items.Add(str);
}

First let's clear up some confusion:
1. You can't use static variables to store user specific data, as a static variable is shared by all threads.
2. A hidden field is only useful if you want to send the value from one page to the next, as an alternative to relying on the session.
3. A session variable can not become null during the execution of a page. If it exists when the execution starts, it will exist when it finishes.
In your code you put the value in the variable userId, just use that variable. There is no reason to put it anywhere else during the execution of the page.

MyConnection.Open()
MyAdpapter.SelectCommand = MyCmdSelect

Hi all,
Anyone please tell me whether the whole page is posted back after an event in .net 2005 web pages ( eg: after dropdownlist selected index changed or button click) or is it like an ajax enabled component since code-behind file is now a partial class rather than a full class that inherits from the ASPX page. Please explain.
Thanks in advance.

The partial class is only used to separate your code and the auto generated code into two separate files, it's still compiled into a single class.
The postback still works the same, and the aspx page still inherits from the codebehind class (not the other way around).

Hi Guffa
Guffa wrote: The partial class is only used to separate your code and the auto generated code into two separate files, it's still compiled into a single class.
Which auto generated code you are referring to here.Do you mean vb.net code. I'm also confused about these partial classes. Partial class allows private part of other class to be accessed.thats OK but asp.net page still derives from codebehind so isn't it difficult to digest? Pls elaborate.
Thanks

A partial class is just a class that is split into separate parts.
public partial class A {
... some code
}
public partial class A {
... some more code
}
is the same as:
public class A {
... some code
... some more code
}
The auto generated code is the code that is automatically created to interface with the server controls in the page.
For example, if you have a Label named InfoLabel in the page, a reference is created for it:
public protected Label InfoLabel;

Hey Folks,
I have been having some difficulties implementing the ChangePassword control to use the ActiveDirectoryMemembershipProvider. Any help or incite that you can provide would be most appreciated! Thanks in advance.
From within our webapp, despite the strength of the password used, when the ChangePassword control calls ActiveDirectoryMemembershipProvider.ChangePassword() function, a MembershipProviderException is thrown with the following description:
"The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements. (Exception from HRESULT: 0x800708C5)"
However, the password policy for AD users is set as follows:
1) Enforce password history = 0 passwords remembered
2) Maximum password age = 0
3) Minimum password age = 0 days
4) Minimum password length = 8 characters
5) Password must meet complexity requirements = disabled
6) Store passwords using reversible encryption = disabled
(The AD server was rebooted)
Here are the configuration of the membership provider in the web.config:
<membership defaultprovider="MyADMembershipProvider">
<providers>
<add connectionstringname="ADConnectionString"
="" connectionusername="dev\administrator" connectionpassword="Password!" enablesearchmethods="true" name="MyADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionprotection="Secure" enablepasswordreset="true" requiresquestionandanswer="true" requiresuniqueemail="false" maxinvalidpasswordattempts="1000" minrequiredpasswordlength="8" minrequirednonalphanumericcharacters="0" passwordstrengthregularexpression=".*" attributemapusername="sAMAccountName" attributemappasswordquestion="UserPasswordQuestion" attributemappasswordanswer="UserPasswordAnswer" attributemapfailedpasswordanswercount="UserFailedPasswordAnswerCount" attributemapfailedpasswordanswertime="UserFailedPasswordAnswerTime" attributemapfailedpasswordanswerlockouttime="UserFailedPasswordAnswerLockoutTime">
As you can tell from the password policy and the web.config, we have opened this wide up. The strange thing is that we are using the AD Membership provider and ChangePassword control right out-of-the-box, with literally no customization at all, so we are at a bit of a loss here.
Has anyone else successfully implemented this? Any thoughts?

How can i achieve this?
I want to get the MAC Address of the user Network Card. What are my options?
Does IE have an function for this ?
Is it possible through scripting ?
Will it work through a ActiveX Control ?
Thanks in advanced
|
|
|
|

I doubt IE would have the necessary security priviledges - my guess would be an ActiveX would be the only way, unless the web server's variables can help?
