i user this code to get all users on the domain but it only returns me 1,000 users the problem is i have over 3,000 users in my domain what can i do to get the entire user list from AD
public static ArrayList GetAllADDomainUsers()
{
string domainpath = @"LDAP://DC=tshospital,DC=com";
ArrayList allUsers = new ArrayList();
DirectoryEntry searchRoot = new DirectoryEntry(domainpath);
DirectorySearcher search = new DirectorySearcher(searchRoot);
search.Filter = "(&(objectClass=user)(objectCategory=person))";
search.PropertiesToLoad.Add("samaccountname");
SearchResult result;
SearchResultCollection resultCol = search.FindAll();
if (resultCol != null)
{
for (int counter = 0; counter < resultCol.Count; counter++)
{
result = resultCol[counter];
if (result.Properties.Contains("samaccountname"))
{
allUsers.Add((String)result.Properties["samaccountname"][0]);
//allUsers.Add(result.GetDirectoryEntry());
}
}
}
return allUsers;
}

You have to perform a paged seach, you can't exceed the server side limit of
1000 objects returned.
See DirectorySearcher.PageSize [^]property.

PLEASE HELP ME TO GENERATE DYNAMIC CRYSTAL REPORTS BY SETTING DATE AS PARAMETER FIELD.

Umm, take it easy with the capitals.
What's the problem?
|
|
|
|

it has no answer.i searched a lot on the web.but you search again for it. you may find it. i made a
code to serialize it into xml and create a dynamic report.
i have this code for microsoft reports(.RDLC) it is not CrystalReport but it may solve your problem. it is incomplete. and also has errors. its incomplete because i tried to print my views directly.
if you fixed it send it to me.

The below command writes not fast enough. Is there any way to fasten it.
Stored procedure is not an option for now.
It writes to Access via data reader from as400
<pre> olecmd.CommandText = "INSERT INTO NXAC08 " + "([Article], [Store], [Year], [Month], [Day],
[Unit], [Value], [Discount]) Values (" + dr["Article"].ToString() + ", " + dr["Store"].ToString()
+ ", " + dr["Year"].ToString() + ", " + dr["Mounth"].ToString() + ", " + dr["Day"].ToString() + ", "
+ dr["UNIT"] + ", " + dr["VALUE"].ToString() + ", 0)";
olecmd.ExecuteNonQuery();</pre>

Ladies and gentlemen, please fasten your .. datareaders?
I assume you want it to be faster, but I see absolutely no way to do that. This is a string. Creating it is fast enough. If the database is being slow than your database is slow, but then we already knew that since you are using Access.
Solution: don't use Access.
|
|
|
|
|
how fast or slow is it? how did you establish that? is that for the first insert only, or have all your insert commands such speed? and how fast do you want it to be?

If you execute this code many times you can probably hasten it by using parameters (and eliminating the ToStrings).

Hi,
There is a string such as:
string s = "12445-65432 abc, 98767-45364 th, 56749-23198"
How can I remove the letters so that I end up with:
s = "12445-65432, 98767-45364, 56749-23198"
Thanks

Use
Regex.Replace("your String", "[A-Za-z]", "");

forget regex, simple function...
public string RemoveLetters(string original)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
for(int i = 0; i < original.Length; i++)
{
if(!char.IsLetter(original, i))
sb.Append(original[i]);
}
return sb.ToString();
}
EDIT:
 my answer does exactly what is required, how it get 2 'bad answer' hits?
 3.0 - getting better...
4.0 - much more respectable, thou it can never be a 5...

At the risk of starting a flamewar how is
public string RemoveLetters(string original)<br/>{<br/> System.Text.StringBuilder sb = new System.Text.StringBuilder();<br/> for(int i = 0; i < original.Length; i++)<br/> {<br/> if(!char.IsLetter(original, i))<br/> sb.Append(original[i]);<br/> }<br/> return sb.ToString();<br/>}
Simpler than:
Regex.Replace("your String", "[A-Za-z]", "");
Despite the common belief that string builders are better, they are inefficient for most applications, it'd be much quicker cycling through an array of chars (a-z) (or their equivalient integer values & converting) and removing them in a loop.
The regex will allow other caracters he'll probably need to remove to be added with ease.

|

I didn't say it was simpler, just there is a simple way of doing it yourself.
If you loop the chars you will have to create a new string with each remove anyway. I don't know the exact performance difference so I'm not trying to argue its better in that respect. I just basically like to give answers that show the logic involved (when its a simple task like this), that way people can learn the logic and apply that when 'out the box' functions either are not available or simple don't do exactly what you want.
For example, lets say the OP really wants to do this task over a 1GB file with a background worker. Now obviously you don'd load 1GB into a string, you would do a ReadByte loop or something similar, but my method shows how easy it is to detect if a character is a letter and then progress can be reported after each loop (or 1000 loops etc.)
Don't get me wrong, was not trying to start an argument, both Regex suggestions are perfectly valid - just wanted to give an alternative

Probably because this is a homework / study question and regex is out of the scope of the educational material for an intro / basic course. The teacher will be looking for a students understanding of the logic of loops and methods within the char class over regex at this point.
|
|
|
|

So actually giving them the Regex answer is a Good Thing, as the teacher will instantly know that they have shown no understanding of the problem and have simply asked an online forum for the answer.
Answering this questions correctly is getting more and more difficult.

No, the exam will prove that by itself.

Hi,
the regex approach is easy to write, however it is not very CPU-efficient; in my test it was between 8 and 9 times slower than the StringBuilder plus for-loop approach. And StringBuilder *is* the right approach when one has to perform a reasonable number of concatenations, since, without them, each operation would have to create a new string and copy its content (a quadratic cost).
When more complex character collections have to be removed, isAlpha is not useful anymore, IndexOf could be the right approach; it would slow down the for-loop by a factor of 2, however the regex also slows down when adding to the search set.

I din't vote you down, but the first line of your answer I didn't like.
"Forget regex" sounds like you were saying regex was not the right choice - in actual fact it is certainly something you should consider for this sort of task. But I think you know that and the "forget regex" was a flippant remark.
Anyway, it was a good enough answer.

your right... I meant no offence to Regex or it's users

Hi,
Any idea how to capture a router's amount of data transferred (Sent/Received)?? You know, you're browsing the internet and want to know how many bytes you've used so far since morning for example..
Thank you.
All generalizations are wrong, including this one!

You could try UPnP..
Or just use Networx[^] if you just want to know the number and don't mind not having programmed it yourself
|
|
|
|
|
|
I use NetMeter[^] which gives daily, weekly, monthly and complete totals (for your PC, not the router which may be shared). Freeware, works fine.
