That's a bit of a big ask unless the machines are on a domain administered by Active Directory Services!!

Erm... have a look at the DirectorySearcher and Directory Entry classes. They are mainly for Active Directory but I think WinNT which is a ADSI provider protocol (NT4) is supported so you might be able to use that... Otherwise it's Win32 API time... and at the moment I have no idea where to start...

Sorry!

Frown | :(

I'll certainly give it some thought!!!

No probs.. I'd be interested in knowing how you get on as I can't try the calls on a non-AD network... (AD city in this building!!)

Dynamic radioButtons

Hey,

I have a collection of objects. For each object in the collection I want to show a radiobutton on my windows.form.
ex.
O Object1.fieldname1
O Object2.fieldname1
O Object3.fieldname1

The problem is thatI have to create the radiobuttons dynamically, because I don't know how much objects are in my collection.

With a combobox there is no problem. I just use there a datasource, a displaymemeber and a valuemember.
But now, intead of having a combobox, I want it in radiobuttons.

I thought a radiobuttonlist was a solution, but that is only for webcontrols.
Or maybe I can play with the groupbox where the radiobuttons come in?
How I create a radiobutton at runtime??

Maybe somebody have an idea?
Thanks in advance,
Nic

Remote File Access??

I'd like to access files in remote computer.

However I hardly know how can I access.. Frown | :(

What I want is,,

One client accesses to a server, and it checks some of files updated
(I think it is possible to identify modified date of file.)

And If some of file had changed, the client download the files from the server.

How can I do to make it? Thanks..

I'm not who I was

Is there event before a window form closed?

11-Jun-03 23:03

Not quite sure what it is you're trying to ultimately achieve but I would probably stick the file in a Web folder and then use the HttpRequest classes etc to get the file info and download the files.

It's certainly a better idea than just sharing a folder. Will it just be on a local network or reachable over the internet!?

There's Closing, Close, QueryUnload, and Unload. Look 'em up! Wink | ;)

Xpelive,

The event you're looking for is Closing. The best way I have found to locate an event handler that is supported by an object is to select it in VS and look at the events list in the Properties pane... (press the lightning bolt button)... you can then select interesting looking ones and press F1 to get help on it!!!

Does C# have a string function like CString of C++ ?

Hi, Friends! Does C# have a string function like CString of C++ ? but the C#' String is too small or I must to inheritance String and write a new class ? thx!

Re: Does C# have a string function like CString of C++ ?

10-Jun-03 22:05

Well there's the string class/type... which maps to System.String which has pretty much all of the functionality of the MFC CString.

The problem is that it is marked as sealed which means you can't derive a new class from it... you could contain a string object in another class then write your new methods to work with the contained string...

What is it you actually want to do?

10-Jun-03 22:34

Can't you use IndexOfAny()???

e.g.

<br />
string myString = "Hello Dave, how are you today?";<br />
string searchString = "Dave";<br />
<br />
bool isSubstring = (myString.IndexOfAny(searchString)!= -1);<br />
<br />
if(isSubstring)...<br />

Had a look at StringBuilder?

System.Text.StringBuilder

In C++, CString does the job of both System.String and System.Text.StringBuilder.

marshalling

What size should I use to get an equivalent C struct for the type bool?

i.e.
struct
{
DWORD a;
bool b;
} s;

would be
struct s
{
int a;
// bool a; or char a; or byte a; ?
}

...what's the best way to marshal C bools?

bool is not a C data type. Look at the typedef of it.

unsigned char or int? Smile | :)

What does it say in the header file? It all depends how that implementation is defining it.
