I'm looking for book recomendations for developing against Active Directory with C#.
I've gone through the DirectoryServices namespace documentation in the MSDN library, but it falls short in covering the directory entry properties, etc... or I just haven't been looking in the right place.
Any good books or web references would be appreciated.
Thanks,
Jim

Hi, I have been trying to look in the msdn library, but found nothing, maybe because i dont know what i am looking for. If you know how to obtain a list of computers in a domain, it would be helpful if you told me, or told me where to look.
Thanks

In most cases, you can P/Invoke NetServerEnum in the Network Management API. There's no native way in .NET. You could possibly, however, use classes in the System.Management namespace to query WMI if you have an AD WMI provider. I can't remember off the top of my head if one comes with NT by default or now, or if it even exists. That's really about the only way without P/Invoking anything.
You can also use a slew of AD functions, but that will include P/Invoke functions and redefining structs and constants when needed.

Did you check out the System.DirectoryServices.DirectorySearcher class? Looks like it uses ADSI to do its dirty work. Good luck.
Thank you.

Check this control out http://www.codeproject.com/internet/cpop3conn.asp?target=email#Retrieve
You might also want to search a bit more on codeproject, as there are lots of pop3 apps.

thanks for your response!

First thing: pick up a book on programming in C#/.NET. You'll definitely need it because this isn't a drag-n-drop solution and real skill is needed.
Second thing: C# (Csharp as you called it) only targets the .NET Framework. If you don't understand this, you're bound for trouble. You should not only read a good book on this but look over the first few topics in the .NET Framework SDK documentation to understand what .NET is.
Programming isn't something you can just jump into with any decency. If you want to learn, start basic. Creating an email application - especially one that uses specifications like POP3 - isn't an easy task. Start simple like just creating a simple Windows Forms application with a toolbar and some controls and make it do something.
CodeProject here offers a lot of articles for newbies and experienced developers alike. These forums are great for asking questions if you don't understand something in the documentation, but you should at least check the documentation first. Being able to research a problem is very important in any field - especially in programming. It's also a good idea to look over the .NET Base Class Library (BCL) to see what's available because there's a lot of things that can help, although nothing will solve your immediately problem directly.

hi,
i want to build a sql statement like following using DateTime field in where clause. but, it return invalid format.
strcmd = "select * from table_1 where datentime = '11/12/2003 17:45:34'";
// where type of 'datentime' is DateTime.
any method to convert a DateTime variable in C# into DateTime field in MSAccess?
thanks,
jim

AFAIK, you should be able to use the same standard date format as in SQL Server. What about this?
strcmd = "select * from table_1 where datentime = '2003-11-12 17:45:34'";
Thank you.

i did not try your format.
but, i have found a keyword to solve it.
take a look at below!
strcmd = "select * from table_1 where datentime = #12/31/2003 17:45:34#";
date format should be in this format, MM/DD/YYYY
thanks,
jim

Be careful, as Jeff suggested use the ISO date format of YYYY-MM-DD becuase if its run on a machine with different regional settings you may get caught out. If you use the ISO with the year leading in, Access recongnises this correctly. 11/12/03 can be interpeted as Nov 12 on a US machine, but on a UK machine its Dec 11.
Yes for dates you are supposed to use # instead of ' with Access. You can see the query builder add them in for you in Access.

This is my conn string :-
server=Earth;database=Test;uid=Nish;pwd=nish123
Nish is a SQL server db user I added for the Test database using Enterprise Manager (today is the first I am seeign this weird app)
It says :- Login failed for use Nish; Reason: Not associated with a trusted sql server connection
Damnit that sucks. The sql server is running on this same machine (earth)
I am usiong System.Data.SqlClient.SqlConnection

Does adding Integrated Security=false make a difference?
I only ever use Windows Authentication, but according to MSDN
Integrated Security
-or-
Trusted_Connection
'false' When false, User ID and Password are specified in the connection. When true, the current Windows account credentials are used for authentication.
Recognized values are true, false, yes, no, and sspi (strongly recommended), which is equivalent to true.

Have you tried this at the command prompt? This solved a similar connection problem on my computer.
osql -E -S (local)\DBNAME -Q "sp_grantlogin 'MACHINENAME\ACCOUNTNAME'"<br />
<br />
osql -E -S (local)\DBNAME -d Pubs -Q "sp_grantdbaccess 'MACHINENAME\ACCOUNTNAME'"<br />
osql -E -S (local)\DBNAME -d Pubs -Q "sp_addrolemember 'db_owner', 'MACHINENAME\ACCOUNTNAME'"
Substitute elements in UPPERCASE with the relevant informantion from your specific case.
Note: Contrary to you, I was using Windows Authentication instead of SQL Server Authentication.

Nish,
I apologize in advance if anything I say is stupid. I've never used SQL Server with Windows authentication at all.
In Enterprise Manager, go to your server, then Security - Logins. Right-click on the user in question and bring up the properties. Does it look like the user is set up to only use SQL Server authentication? Now, is the Test database set up so that it only accepts trusted Windows-authenticated user connections? Also, is it possible to add the user to the BUILTIN\Administrators group as a troubleshooting step?
Thank you.

Try this:
Data Source=Earth; Initial Catalog=Test; User ID=Nish; Password=nish123; Integrated Security=false

hi there:
i have a dataset called "Employees", that have two tables "employees"and "jobs",employees have a foreign key called "jobid" that refrence the primary key "jobid" in the "jobs" table and tied together,i have a datagrid that each record of it have columns from "employee" table and have one column called "jobDesc", i write the following function to get the "jobDesc" column from "jobs" table by the foreign "jobid"column in the "emplyee table...........I want to translate this function into method in c#
Public Function BindJob(ByVal o As Object) As String
Dim drv As DataRowView = o
Dim dr As Employees.employeeRow = drv.Row
'Dim dp As Employees.jobsRow = dr.GetParentRow("jobsemployee")
'Return dp.job_desc
' Alternatively, since this is strongly typed:
Return dr.jobsRow.job_desc
End Function
|
|
|
|
|
public String BindJob(Object o){ //forget about ByVal
DataRowView drv = (DataRowView)o;
Employees.employeeRow dr = drv.Row;
return dr.jobsRow.job_desc;
}
|
|
|
|
|
this casting is not working
DataRowView drv = (DataRowView)o;
error msg:
Exception Details: System.InvalidCastException: Specified cast is not valid.
|
|
|
|
|
No my fault 
If you don't pass a DataRowView, is can not be used as a DataRowView.
Try Console.WriteLine(o.GetType()); to find out, what is really is.

Does anyone know how to loop through all icons in an embedded folder and populate an imagelist. As seen below, I have an embedded folder Prud.Library.Icons.State which contains a set of icons. I would like to add all Icons in State to an ImageList regardless of their name.
Does anyone know how this can be done?
Thanks heaps.
Note: string sIconName = "Prud.Library.Icons.State.Icon1.ico";
System.IO.Stream objStream = null;
System.Drawing.Icon[] objIcon;
try
{
/*
* Stream Icon and add to ImageList
*/
objStream = this.GetType().Assembly.GetManifestResourceStream(sIconName);
if (objStream != null)
{
objIcon = new System.Drawing.Icon[1];
objIcon[0] = new Icon(objStream);
}
}
catch (Exception err)
{
throw err;
}
finally
{
/*
* Dispose of Stream Object
*/
if (objStream != null)
{
objStream.Flush();
objStream = null;
}
}
return objIcon;
