I'm able to see the values by using the code below when I run through the debug step by step (in Visual Studio) and then I use the mouse to expand child items, but I cannot access the child items through code?

Has anyone ever experienced that before?

Then the real problem is that you want to do something more complicated and that the code given doesn't provide an exact solution.

I would suppose that there is a way to do it.
I would also suppose that it will require reading the documentation, experimenting and guessing to get to a solution. Similar to other programming tasks that one might encounter.

Hi,

Here is what I have, and so far this is working. It is far from finished and sorry for all of the comments, but I just got it working. It works for get-mailbox -identity first.last, it works for get-alias and it works for test-servicehealth. It itterates through everything, but it is a start Smile | :)

I'm sorry for the post length, I thought that codeblock would limit the screen usage and put a scrollable window within the post. If anyone knows how to do that, please let me know.

VoIP with C# on a 64Bit Windows 7

Hello
I have some problems with VoIP.
I'm working on a P2P VoIP Application with C#. There are around 6 examples in the Internet, but none of them work. When I use the dll files of the librarys (Open h323, TAPI3...), it shows me an error:"COM Not registered".

Does anyone know an easy to use library, working with Visual Studio 2010 Ultimate and Win7 64Bit.

I've tried all the examples below
Examples to create your Conferencing System in .NET, C# VOIP & Video Conferencing Systems using H.323 and TAPI 3[^]

Thx

If the examples use a COM component you need to register it first (either by running its installer or on the command line with regsvr32).

FTP Problem

I have this FTP code. I'm trying to get a list of files from the server. All it returns is an entry for the root folder.. Using FileZilla and/or CuteFTP I can see the subfolders and files in them. Why isnt't my returning anything other than the root folder?

public struct FTPCredentials
{
    public string FTPServer { get; set; }
    public string UserName { get; set; }
    public string Password { get; set; }
}

public List<string> GetFileList(FTPCredentials Credentials)
{
    List<string> retVal = new List<string>();

    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(Credentials.FTPServer);
    request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
    request.KeepAlive = true;
    request.UsePassive = false;

    try
    {
        request.Credentials = new NetworkCredential(Credentials.UserName, Credentials.Password);

        FtpWebResponse response = (FtpWebResponse)request.GetResponse();

        Stream stream = response.GetResponseStream();

        StreamReader reader = new StreamReader(stream);
        string line = reader.ReadLine(); 
                
        while (!string.IsNullOrEmpty(line)) 
        {
            retVal.Add(line);
            line = reader.ReadLine(); 
        }

        reader.Close(); 
        response.Close();
    }
    catch (Exception e)
    {
        throw e;
    }

    return retVal;
}

Everything makes sense in someone's mind

FTP works similar to filesystem operations, so requesting anything from the server will work only in the current working directory. Since you're using FtpWebRequest, you'll also need to think of your FTP 'session' more in terms of HTTP style communications (browsing an FTP site using a web browser instead of an FTP client). You make one request, and you get one response. When you create the request:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(uri);

The variable 'uri' is actually both the server and the full path of your working directory. So if you want to connect to ftp.server.com and get the directory contents of path 'some/path', you would create your FtpWebRequest like so:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.server.com/some/path");

If you want to monitor how FTP actually communicates with ftp servers, enable the messages view in FileZilla (View > Message log). These are all happening implicitly when using the FtpWebRequest object.

I'd recommend finding an FTP library (or writing your own if you have the cohones, several RFCs make up the spec now) if you're going to be doing anything more than simple FTP operations.

Thanks for the response. I think I understand. Some comments...

I set up a test FTP folder:

FTPServer = "ftp://ftp.maroisconsulting.com/test",
UserName = "FTPTest", 
Password = "testftp"

When I run the code, I get the exception:

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

I'm sorta lost here. I don't understand why this doesn't work. The folder exitst with 2 test files in it. My FTP Client (FileZilla )works, but not this code.

Everything makes sense in someone's mind

Based on the error number, your FTP client is connecting and authenticating without any problems. The problem seems to be realted to the server. It's possible that that access is denied to the file/directory (either by permission or file lock). If you have access to the server, verify the permissions for user FTPTest. You also might want to verify that the FtpWebRequest object credentials match your FileZilla settings exactly.

You could also try it against another FTP server you have access to and verify it. You code works for me when I tried it against both anonymous servers and my own.

Reverse (2-way) synchronization: DataGridView to Table (Database)

I am attempting to accomplish 2-way synch from a DataGridView to a table in my database. DGV to table is easy, but is there a "best practice" way to have the DGV automatically update to reflect any changes made to the database?

I tried using a timer and perform a TableAdapter.Fill(DataSet.SomeTable) at regular intervals, but the problem with this approach is that it "clobbers" any edit in progress, and resets the selected row to the top. Preferably, I would avoid impacting the user so directly.

Thank you...

EDIT: Here is how I am synching DGV changes to the database:

private void dgvSomeView_RowValidated(object sender, DataGridViewCellEventArgs e)
{
    myTableAdapter.Update(myDataSet.MyTable);
}

I don't know this game, but here are some pointers:

1. Always use { and } even on single statements.
2. Avoid multiple returns
3. As I said, but why are you using and IsEmpty boolean array which I assume is 'synchronized' with the labels array? You can pass your labels array and check whether the label is empty or not. eg( string.IsNullOrEmpty(lbl_array[x,y].Text) )
4. You don't check if x and or y is within the array size, you can get an arrayindexoutofboundsexception error
5. You hardcode all variables, if you want to change the game to a 10*10 matrix you'll have a fun time changing all the variables.
6. make sure you name your variables so they mean something. I have no idea what fx, fy, sx, sy, ftx, fty, ... are for.
7. One statement, one line avoid: sdx--; sdy--;

this should help you already.
Don't mind the homework remark, you showed you tried something yourself, whether it is homework or not is irrelevant.

Those don't really have anything to do with optimisation, and most of them (1, 2, 6 and 7) are matters of opinion, of which I only agree with one (6, and even then, those names might well be meaningful if you know the game).

Depends on what you mean with optimisation.

You don't have to agree, but I wouldn't want to debug your code if you write it like that. (I'm not saying your code is bad nor is it wrong)

I'm not missing them, I just don't agree with them Wink | ;)

(Or, to be less glib, they come from good principles, but when applied as fixed rules, they make things less readable, generally by expanding the code so that you can't see the pattern of it any more. In the case of the example posted here, decrementing both the x and y variables in one line makes sense because it's one thought, for example.)

There is nothing wrong with multiple returns, though. Checking a condition within a foreach loop and returning when it's hit is quite common and perfectly readable (arguably more so than assigning to a variable and breaking since you can see that it's an exit point).
