It's pretty straightforward. Make a form, add the necessary controls, query the database against what the user has entered in the textboxes, ... What else you need?

Hi,
Iam writting a c# DLL for users login. Here i need to get the machine name of the client who is accessing my class. In case if we are designing a website we can write the following code to get the machine name
string[] aStrComputerName = System.Net.Dns.GetHostEntry(Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
string strMachineName = computer_name[0].ToString();
But I cant use this code in C# class because Request.ServerVariables is not supported in c# class.
Can any body help me to solve this problem.
Its Very urgent. Thanks in Advance.
Regards,
Suresh Kumar G

You can use Environment class.

It's urgent only for. CP members don't reply to posts based on how urgent it is. They just want to share their knowledge and help newbies so it really doesn't make difference if it's urgent for you or not.

You can access the server variables using HttpContext.Current.Request.ServerVariables.

float num = 18.3f;
This above stmt will run,But I read in a book that "if 18.3
taken as a double, so you would get a compiler error saying that a double cannot be implicitly converted to a float. Adding the f to the end of 18.3 does an explicit conversion."....But how is that possible?If we can cast Double value to int then why not convert Double to float? (Float is almost double ,right?)
|
|
|
|
|
If any value cannot be expressed fully with no loss when converted (i.e. 3.3 as an int is 3 so we lose .3), then it should use Explicit conversion. If however, if it will be identical when converted it should use explicit implicit 3 as a double still == 3).

In this case you're not casting; casting would be float num = (float) 18.3; which would also work, but it still has to be done explicitly just as it would be for double-to-int.
|
|
|
|
|
18.3f is not a cast or a conversion it just tells the compiler to treat the literal as a float instead of a double.

I working with Active Directory Reset password.
DirectoryEntry DirEntry = GetDirectoryEntry();
DirEntry.UsePropertyCache = false;
DirEntry.Invoke("SetPassword", new object[] { newpassword });
DirEntry.CommitChanges();
The code is working fine but after changing the password I am able to login with both old password and new password. I found with my observation that after one hour approximately the old password expires.
Is there any way to expire the old password immediately when I change the password?

Currently I am using a test domain setup on a test machine. So there is only one Domain Control.

Assume you perform login authentication with code below :
bool loginResult = false;
using (DirectoryEntry de = new DirectoryEntry(this.SearchRoot.Path, userDN, password, AuthenticationTypes.Secure))
{
try
{
object x = de.NativeObject;
loginResult = true;
}
catch (COMException comEx)
{
}
return loginResult
}
Just Change the AuthenticationTypes to AuthenticationTypes.Secure will solve the problem. If the AuthenticationTypes is AuthenticationTypes.None then it will able to login with old password.

Hi there
I have a file with allot of sentences. I need to make a dictionary with the words from that file. Until now I've separated the words and sort them using Split() and Sort() methods. My problem is to make a list without duplicate words. How can I do that?
static int n = 0;
public static string[] NoDuplicate(string[] array)
{
int i;
string[] res = (string[])array.Clone();
for (i = 0; i < array.Length-1; i++)
if (array[i + 1] != array[i])
res[n++] = (string)array[i];
return res;
}
1) how can I do it more neat?
2) i don't like that method because is initialized using Clone() and the lenght is too big.
many thx

Store words in dictionary. Before adding new word check if the dictionary already contains it or not.
|

First, I'd use a List instead of an array because a List can grow dynamically, and will only be as large as is required to store your data. To avoid duplicates, you could do this:
List<string> dictionary = new List<string>()
string sentence = GetNextSentence();
string[] words = sentence.ToLower().Split(' ');
for (int i = 0; i < words.Length; i++)
{
if (!dictionary.Contains(words[i])
{
dictionary.Add(words[i]);
}
}

Instead of using a List and calling it a dictionary, use a real Dictionary.
The Dictionary.Contains method is a lot faster than the List.Contains method.

|

why would you need key & value just to store a word though? I would've gone with John's suggestion myself.

The difference is the style of the storage object.
A list is just that, an unsorted sequential list of items. To do a Contains() operation on it, you have to iterate through the list and check every item.
On the other hand, a dictionary is a form of hash table, so a Contains() operation only has to hash the key and check if it already exists.
in .net 3.5 you could instead consider a HashSet<String> This is specifically optimised for sets containing no duplicates.
