so, I do a the following:
<br />
...<br />
m_nHeight=20;<br />
m_nWidth=10;<br />
...<br />
m_board=new Block[m_nHeight, m_nWidth];<br />
for (int i=0; i < m_nHeight; i ++ )<br />
for (int j=0; j < m_nWidth; j ++ )<br />
m_board[i, j]=new Block();<br />
but a strange thing, I have inserted a trace inside the constructor of the Block class, and when I look at the trace, instead of having 200 calls of Block.Block, I have 400 calls  20x10=200...

You had a trace in your Initialize method before. Are you sure you're not getting 200 lines with "Block.Block" and 200 lines with "Block.Initialize"? If not, I'd really need to see the rest of the Block class code and the full creation block in which you gave a fragment of above.

Hi Heath,
I have rebuild the code, and indeed, there are 200 calls now 
Thanks

Hi!
I use RemotingConfiguration.RegisterWellKnownClientType(typeof(type),url) to register a type as a wellknown client type. Is it possible to unregister this type to register it again with another url (or to change the url for the registered type) without restarting my application?
|
|
|
|

First, let me advocate that a well-known client Type can't be well-known if you change its URI.
That being said, you can use RemotingServices.Disconnect. If you have a reference to the registered object, just pass it to the static Disconnect method. If you don't have an instance of it available, you can get one using other methods of the RemotingServices class.
Registering it with another URI is as simple as what you've already done.
Another way is to simply shut down the .NET Remoting host, such as a Windows Service, IIS, or some other program, but that's most likely not what you want in this case.

Hi!
Thanks for your effort!
Unfortunately doesn't work it...
I want to explain the situation more detailed:
When the client starts his application, he get's a login-dialog, where he has to type in the servername (and username, password ....) he wants to connect to. When the client types in a servername, that does not exist or the server is not available, he must get a new chance to login, without restarting his application.
When he clicks the Login-Button I do something like this:
<br />
Dispather MyDispatcher;<br />
RemotingConfiguration.RegisterWellKnownClient(typeof(Dispatcher),URL);<br />
MyDispatcher=new Dispatcher();<br />
MyDispatcher.Login(...);<br />
...<br />
If an error occures (severname incorrect or server not available) I have to unregister this Dispather-object first, before I can register it again with another URL. RemotingServices.Disconnect(Dispatcher) does not work, because it's for Serverobjects. And Reregistering (with RegisterWellKnownClient) throws an exception ("System.Runtime.Remoting.RemotingException: Es wurde versucht, die bereits umgeleitete Aktivierung des Typs 'Dispatcher, ccShared' erneut umzuleiten.").
What can I do?
Thanks in advance!

I found a solution for this problem by myself!
My Server marshals the Serverobject (RemotingServices.Marshal) and my Client connects that object (RemotingServices.Connect).

Hi, I'm seeking a way to emulate "Send To" function.
I just need to pass a file to .MAPIMail (it can pass a file to the default mua). .MAPIMail is normally located in C:\Documents and Settings\Default User\SendTo\ but doesn't have to use them. Simply prepare a file named like foo@test.local.MAPIMail (zero-byte) and drop a file with explorer. It'll attache the file to the default mua.
If anyone knows about this, please let me know. I'm willing run the default e-mail client and a file attached.
Thanks in advance.

I want Send To function for one of my C# projects too and in that time I couldn't find a .NET way for it, so I wrote a Shell Extension which do some task for my SEND TO function and register it with my application. But as I'm thinking now , those steps are doable in .NET too(not sure). This[^] article show you the VC6 way. If you couldn't translate it to .NET at least you can make that dll in VC6 which handle your job.

Thanks Magy. So, it sounds like there is no way in C# and I at least need to import a dll.

Hi,
I have the problem to get the selected text of a TreeNode. I want to put the selected text of a TreeNode into the clipboard. But I found no solution to get the selected text.
Is there anybody who has an idee?
Regards
Frank

When you say selected text you mean the user has "highlighted" a portion of the node label with the mouse and you want that higlighted text only ?
|
|
|
|
|
Yes, I mean (like in TextBoxes), the part of the text which is selected (with the mouse or with the keyboard).
Only when the TreeNode is in edit mode (SelectedNode.IsEditing).
|
|
|
|
|
Have your tried casting the selected node as TextBox and using the SelectionStart and SelectionLength properties ?
|
|

Another not-so-simple resolution would be to create your own TextBox and handle the edits yourself.
private void tvTestTree_BeforeLabelEdit(object sender, System.Windows.Forms.NodeLabelEditEventArgs e)
{
e.Node.EndEdit(true);
TextBox MyEdit= new TextBox();
Rectangle IRect = e.Node.Bounds;
MyEdit.Location= new Point(IRect.X,IRect.Y);
MyEdit.Width=IRect.Width+20;
MyEdit.Height=IRect.Height;
MyEdit.Text=e.Node.Text;
tvTestTree.Controls.Add(MyEdit);
}
You will probably have to add an event handler for the TextBox to close it and get the selected text...

Sorry, I had to work.....
Thank you both for your ideas. I'll try both of your solutions. I thought already at this. But I hoped to get an easier solution.
Whatever thanks for your efforts...

You can't cast a TreeNode to a TextBox.

This should work, but you can also get the edit control (a TextBox in .NET) that the Tree-View common control uses during label edits by handling the TVN_BEGINLABELEDIT notification message in TreeView.WndProc and then call a P/Invoked SendMessage with the TVM_GETEDITCONTROL:
public class MyTreeView : TreeView
{
private TextBox editBox;
protected override void WndProc(ref Message m)
{
if (m.Msg == TVN_BEGINLABELEDIT)
{
IntPtr hWnd = SendMessage(this.Handle, TVN_BEGINLABELEDIT, 0, 0);
if (hWnd != IntPtr.Zero)
this.editBox = (TextBox)Control.FromHandle(hWnd);
}
else if (m.Msg == TVN_ENDLABELEDIT)
this.editBox = null;
}
[DllImport("user32.dll")]
private static extern IntPtr SendMessage(IntPtr hWnd, int msg, int wParam,
int lParam);
private const TVN_BEGINLABELEDIT = 0x10c5;
private const TVN_ENDLABELEDIT = 0x10c4;
private const TVM_GETEDITCONTROL = 0x110f;
}This way, you're not overlapping controls which can lead to problems, and you'll have to handle all the getting and setting of text.

This method is what I was referring to when I suggested casting the TreeNode edit control to a TextBox, except you said it correctly, I didn't. My Appologies....

I'd like to perform the following function but without using a temporary text file, can someone point me towards how to do this in memory ? Is it possible ?
private void FillClipBoard()
{
string Line;
bool FoundDollar=false,Start=false;
TextReader trFile = File.OpenText(WorkingDir+CurrentName);
StreamWriter sw = File.AppendText(WorkingDir+"Clipboard.txt");
while((Line=trFile.ReadLine())!=null)
{
if(Line.StartsWith("$"))
FoundDollar=true;
if(FoundDollar)
{
if(!Start && Line.Trim().Length==0)
continue;
if(!Line.StartsWith("$"))
Start=true;
else
Start=false;
}
if(Start)
{
sw.WriteLine(Line);
}
}
sw.Close();
trFile.Close();
Utils.PutClipBoardTextFile(WorkingDir+"Clipboard.txt");
File.Delete(WorkingDir+"clipboard.txt");
}
public static void PutClipBoardTextFile(string Path)
{
TextReader tr = File.OpenText(Path);
Clipboard.SetDataObject(tr.ReadToEnd(),true);
tr.Close();
}

Why not just read this into a string, or better yet a StringBuilder (which is mutable). If you store the reference to this StringBuilder you can keep appending to it. Just use StringBuilder.ToString() to get the actual String.
Another way would be to use a MemoryStream and wrap your StreamWriter or StreamReader around it.
One unrelated thing to your question: instead of concatenating strings that represents directories, you should use Path.Combine to take into account the OS's path separator (\, :, /) and to ensure that - if the WorkingDir doesn't not end with a path separator - that it is added before appending the filename (or additional directory name(s)).

Thanx for the tip.
Does it also check whether the path start with \\ or X:?
Guess I can look that up now that I know where to look
