This means that you cannot add or remove items from the collection while you're enumerating it. foreach creates an Enumerator over the collection automatically.
You can use a normal for statement and index through the collection to do this. I would highly recommend that you start at the end of the collection and work your way to index 0. This will prevent you from deleting an item and skipping the next item in the collection. This is because when you remove an item at one index, say number 5, the items in indexs 6 through whatever all move down one. So item 6 is now at item 5. When your get to the bottom of the loop and the index variable incerements, you're no longer looking at item 5, but instead you're looking at the new item 6. The new item 5 gets skipped over.

hi All,
Suppose GC consists of a number of forests. with ldap search, i found a record in the GC and now want to update this record, but attribute which i want to update is not presented in GC.
how to identify forest this record belongs to and what ldap port i must use to update this record in the forest?

GC, forest? I don't understand what you are taking about. Are you refering to garbage collection? Give a little more detail to your question 
"If an Indian asked a programming question in the forest, would it still be urgent?" - John Simmons / outlaw programmer

Hi Justin, good catch for Indian
GS is Global Catalog (GC). So GC contains info from number of Active Directory forests.
thanks,
max

You may wnat to actually say you're working with Active Directory and "Global Catalog" instead of GC. In .NET, GC normally stands for "Garbage Collector".
The Global Catalog does NOT hold every property of every object. It holds a small subset of properties for all objects.
Your command text probably starts with "GC://...", correct?? Well, to get at the full record, you have to start with "LDAP://...". The port number is there to talk to either the unsecured version of LDAP, or the secured version. What you're doing on that connection has nothing to do with the port number you use. You normally don't need to give it the port number since AD uses the stadnard LDAP ports, 389 for normal connections and 636 for SSL secured.
But, to find the object, all you have to do is return the distiguishedName of the object your looking for from the Global Catalog. The distiguishedName will tell you the full path to the object, including which domain the object is in. You can then use that you get the object from LDAP so you can modify all the properties you want.

Dave, you're right! i work with Active Directory and Global Catalog.
My command text always starts with "LDAP://..." but port is 3268 - port for GC.
i know that 389 port is default port for LDAP. but aslo i know that this port can be changed.
LDAP query i read from 3rd party programm and i don't know exactly would this query will point to GC or LDAP. So if query points to GC i want to find this record tin its forest. Or just LDAP://CN=<distiguishedname> will point to it?

GC queries always start with GC://, so if you're getting this a 3rd party app and it uses LDAP:// to begin it's command string, chances are it's not comming from the Global Catalog.
If you're sure the result is comming from the Global Catalog, and you get the distinuishedName back from the query, that name will point directly to the object in question if you use it in another LDAP command string:
LDAP:
Keep in mind though when you bind to an object, you only immediately get back some basic properties of the object. You need to tell it to retrieve either all of the remaining properties, or just specify which properties you need. After that, you can modify them and write the changes back to AD.

|

ok Dave.
as i know LDAP://distinguishedName/yourParameterList will only work if machine, from what i'm binding to object, belongs to this forest, otherwise i must specify machine name and port in LDAP query, isn't it?
thanks,
max

If you use the distinguishedName, the domain information is already supplied and any controller in that domain can service the request.
No, you don't have to specify the port, unless those domain controllers are not using the standard port numbers.

Dave, thank you very much. i'll try this.
thanks

but, one more question - if these DCs are using non-default ports, how should i connect them?
thanks,

You asked this question yesterday. Do you really think that it's likely that you'll get a reply today if you didn't get one yesterday. Part of the problem is that your post makes no sense in any way. I can read the words, but they don't form a coherent sentence, and you haven't told us what your problem is (apart from an inability to think clearly).
Here on CodeProject we'll help you with specific problems. We won't actually write your applications for you.

Thank you, I update the question, I just need some help.

I don't think any of the standard components can do this. You could look at the available commercial charting/data visualization libraries. If none of them can provide anything useful, or you can't afford their sticker prices you'll have to write your own visualization control.
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop.

Hello All,
just few month ago started to program in C#. It's a great world there!
But I have quite some code written in C/C++, which I want to re-use in my C# development.
In C I have a function exported from a DLL. The function is declared as
EXPORT int my_foo(my_type **Devices, int *nrDevs);<br />
That library is compiled with calling convention Cdecl
I need to call that function in my C# code.
I do the following...
<br />
internal static class MyGreatFunctions<br />
{<br />
[DllImport("my_good_old_stuff.dll", CallingConvention = CallingConvention.Cdecl)]<br />
internal static extern int my_foo(ref IntPtr pDevs, ref int nDevs);<br />
}<br />
<br />
public class MyClass<br />
{<br />
public MyClass()<br />
{<br />
int nDevs = 0;<br />
IntPtr pDevs = IntPtr.Zero;<br />
int r = MyGreatFunctions.my_foo(ref pDevs, ref nDevs);<br />
}
When my_foo is called I got AccessViolationException "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
The other functions (with no double pointers) are called fine. What do I miss here? Why do I get this AccessViolationException? Please! Help!! 
PS
It's WinXP Pro Sp2
.NET 2.0

Hi
have you tried the InAttribute and OutAttribute?
i'm not sure if they're really required in order to work properly but it's worth a try...
<br />
[DllImport("my_good_old_stuff.dll", CallingConvention = CallingConvention.Cdecl)]<br />
internal static extern int my_foo([In,Out] ref IntPtr pDevs, ref int nDevs);<br />
to find out where the error does occur it might be an idea to do
cout outputs in your dll saying what' you're doing and call the dll then from a console app...
greets
m@u

|

thanx!!
In, Out didn't help (but I learned something new)
but cout'ing helped.
BTW, does anybody know how to debug managed/unmanaged code?
I just want to step-in (F11) into unmanaged code from managged... (call using PInvoke)
Regards,
Alex

I never really tried, but i could imagine, if you add your c++ project to the whole solution and set a breakpoint in your c++ method you might be able to do step-in..
without breakpoint it 's possible that it won't step-in because there's much code between without loaded symbol - information. As far as i know, visual studio can not do step in if there's code between calls that has no symbol informations...

Hi!
I know your IAXClient very well! It's awesome masterpiece!
I don't use it. I break it apart - it's my hobby kidding...
btw, libiaxclient interface has changed. I "hybridized" new iaxclient, with your code and existing DotNetWrapper stuff. just for fun, since I don't earn by C# codding...
Kind regards,
Alex
