Can anyone tell me about a simple function that copies all files from one folder in a remote location to a local folder?
For example:
Move all files located in \\Remote\Folder to c:\localfolder
Thanks!

Hi guys.
I have a problem and sorry for the easy (for you) question, but I don't know very well remoting yet.
I must to comunicate between two application on the same machine.
One a web services page with asmx and second a windows application.
It's all ok, and it runs correctly but after some minutes when the web service should comunicates with windows application, it tell me:
System.Runtime.Remoting.RemotingException: No receiver registered.
This is the code:
server
//start the remoting to comunicate with web service
TcpChannel channel=new TcpChannel(1000);
ChannelServices.RegisterChannel(channel);
IuXComunicator obj=new IuXComunicator();
obj.SetServer(this);
ObjRef service;
service=RemotingServices.Marshal(obj,"IuXComunicator");
the class:
public class IuXComunicator:MarshalByRefObject
{
private IuXServer server;
public IuXComunicator()
{
}
public void SetServer(IuXServer Server)
{
this.server=Server;
}
public void SendDueNews()
{
Debug.WriteLine("Requested send news");
server.SendNews(0);
}
}
the client
public class IuXComunicatorClient
{
private static IuXComunicator advisor;
private static TcpChannel channel;
public IuXComunicatorClient()
{
}
public static void AvviseServer()
{
if (channel==null)
{
channel=new TcpChannel(10);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownClientType(typeof(IuXComunicator),"tcp://localhost:1000/IuXComunicator");
}
advisor=new IuXComunicator();
advisor.SendDueNews();
}
}
Please help me.

(the relevent code- i think)
Data is a char array of the last 128 bytes of an mp3 file.
String title = new String(data, MP3_TITLE_OFFSET, MP3_TITLE_LENGTH).Trim();
sw = new StreamWriter(fs);
sw.Write(title);
sw.Flush();
sw.Close();
Example problem: title of the mp3 = "intro", but i created a string with 30 bytes(the possible length of a title) so have a string with 25 null characters.
In debug mode, length of title is 5 and doesnt show the null characters.
When title is outputed to a file the 25 null characters are also ouputed.
How do i remove these null characters from the string?
Thanks!

trimming out a string :
String s = "hello\0\0\0";
char[] cs = { '\0' };
int n = s.TrimEnd(cs).Length;
n = 5

Thanks for all the help.
This is a program I converted from java, the Java Trim works differently from the c# trim when removing whitespace, hadn’t noticed the TrimEnd() method.
I've just discovered that the titles of some mp3s have nuls not just at the end. e.g {O,n,e, ,\0,U,2}. so have written my own method to remove chracters less then 0x20 and greater than 0x7f

Then they are maybe ID3v2 tags...... My class strictly conforms to the ID3v1.1 specification. If it doesnt work, the TAG it self is WRONG!
Cheers
PS: Good luck if you are try to implement ID3v2, I gave up before even attempting it.

No ID3v2 tags.
I have over 8,000 MP3s, my program scans the disks for them and produces a list of mp3s in html. Unfortunately I never created the mp3s for most of the tracks, so some may have no tag at all, or a corrupt tag depending on how they were created – not seen any ID3v2 tags yet. If there is no tag, I simply use the file name.
thanks

I am writing Windows application in C# (VS .NET Release). When exception is thrown by framework in some function (for example, I try to call function of the object which is not created), Visual Studio debugger doesn't point to the line which caused the exception. Instead of this it points to the last line of Main function:
static void Main()
{
Application.Run(new Form1());
} // <- debugger points here
Stack window contains this line and all other lines point to .NET functions.
I found some workaround. In Debug - Exceptions dialog there is exception handling algorithm:
When exception is thrown:
- Break into debugger
- Continue
Standard choice is "Continue". If I change it to "Break into debugger", I have full exception information (stack contains all my functions, debugger points exactly to the needed line).
However, this is not a good solution. If I throw exception in my program, debugger breaks on it also.

Does anyone have a list of the equivilent data types in C# of the MS defined data types of HWND, HANDLE, DWORD, etc..
I need it so I may use it to define some WinAPI calls I need.
Thank you

You can use Marshal.PtrToStructure to convert your unmanaged to managed object.

Have a look at this table(sorry no web link):

Have a look at the Platform Invoke Data Types link, it has a nice table for most conversions

That helped out alot
unfortunately, my findwindow call always returns 0.. That is, when I output it in a messagebox by converting it to a string. How do you put NULL into a string?
[DllImport("user32")]
public static extern System.IntPtr FindWindow(string lpClassName, string lpWindowCaption);
How it's declared..

I implement ::FindWindow in this[^]article.

There is no tool as far as I know (someone from MS responded this in a public MS NG).
But it's an interesting challenge. After all, controls declared in the .rc file must be mapped to C# code. For the set of common controls, I guess it should be easy to do it. The only issue is about dialog units, and stuff like that.
Sh*t...another item in my tasklist..

Does anyone know if this value is where your executable will be installed from an install package. I need to be able to reference a database that will be packaged with the setup and want to make sure the connection string points to the proper location. Right now I am testing in Debug mode and so of course the value that Application.StartupPath.ToString(); returns in inside the Debug subfolder. Does this change with a release version build?

Hi Code Gurus,
(in a C# Windows Form application) How can I access a public member of the form that defines the static Main() member function from another form? I have two forms, frmMain (defind in frmamin.cs) and frmDialog (defined in frmDialog.cs), I want to access a member of frmMain (a property or a function or whatever member) from within frmDialog. When the application runs, the frmMain form is displayed as the application's main window, if the user chooses Connect... from the application's menu, the other form frmDialog is displayed as a dialog using ShowDialog(), now what I want is to access some member fields of frmMain from within frmDialog while frmDialog is displayed as a dialog box (that was extremely easy in VB).
Well, to be more specific, what I want to do exactly is to enable the user to connect to a database, when the user selects Connect... from the menu, a dialog box is displayed to allow the user to enter the database connection information. There is an OleDBConnection object (public member), defined in frmMain, that I want to use in frmDialog (there is a button in frmDialog whose caption is "Connect"). In the event handler of that button I want to use the public member of frmMain (System.Data.OleDB.OleDBConnection m_OleDBConn). For example like this:
myfrmMain.m_OleDBConn.ConnectionString = ... etc

Waleed

define a construtor for the dialogform that takes a parameter of the same type as your mainform. IOW:
public class DialogForm : Form
{
private MainForm parent;
...
public DialogForm(MainForm parent)
{ this.parent = parent;}
...
void SomeFunction(){
parent.OleDbConnection.Connect();
}
}
Thats it Also , dont make OleDbCOnnection public , but rather create a Property for it.
