You can do this with one regex
@"\d*([.]\d*)?"
jeweladdict wrote: if( Regex.IsMatch( token, @"\b[a-zA-z]\w{2,3,4,5,6,7,8,9}\b") )
YOu can shorten {2,3,4,5,6,7,8,9} to {2, 9}.
Expresso is the program you need to test your regex, just google it, I think it's on CP tho.

@"\d*([.]\d*)?" seems to work for IP addresses as well. I tried using the @"\b\d*([.]\d*)?\b" but that didn't seem to help. I'm only looking for numbers that are possible doubles. Any ideas?

I have a problem when I try to copy the richtextbox text to the items in a listbox. Is there a way to stop it from placing the entire richtextbox text as 1 item. below is an example of what I mean.

Split the string on \r or \n, whichever is the delimiter that's causing the boxes you see. You need to split the string, then insert it one line at a time.

I did this and it seems to not be working, im stuck.
myRTF = richTextBox1.Rtf;
while (myRTF.Length > 0)
{
//Find the index of the RTF Return Character
int index = myRTF.IndexOf("\r\n");
//Extract the RTF to that point
string temp = myRTF.Substring(0, index);
//Trim the extracted part of the RTF
myRTF = myRTF.Substring(index, myRTF.Length - index);
//Add the item to your list box
listBox1.Items.Add(temp);
}

This is C#, your string class has a split method. Try splitting on just \r, or just \n. The boxes you get in your list box make me think the rich text control is returning one of those two, and not both. So, call the split method and get a string array, use for each to pass them into the list box.

I did try to do the split on just /n or /r but no luck?

Your slash is the wrong way around. This works:
string text = richTextBox1.Text;
string [] strings = text.Split('\n');
foreach (string s in strings)
{
if (s.Length > 0)
listBox1.Items.Add(s);
}

I have a C# application that acts as a socket listener.
I have another class that is built as a managed C++ dll that processes my data and sends the data back out to the connected client.
My question is, im having problems passing my active connection to the managed dll.
I did something like this:
C# side:
Socket socks;
//lets pretend its already connected, and accepted, huh
int success = ManagedMethod(ref socks);
C++ Side:
SOCKET *socks;
int ManagedMethod(Socket& act_sock)
{
socks = act_sock
}
cant remember what error it gives me, but I know its not right.
On the parameters of this method, I also tried 'Socket *act_sock' and still couldnt pass it.
My goal is to have my Managed C++ dll use this active connection after processing my data and send it to the connected client.
Thanks.

Do you need to pass it as ref from C#? Remember, socks itself is a reference, so passing it by ref would require a pointer to a pointer on the MC++ side.
Assuming you don't need ref, this code compiles fine.
public __gc class Class1
{
Socket __gc * socket;
public:
void ManagedMethod(Socket __gc * s)
{
socket = s;
}
};
From C#, you can pass it as ManagedMethod(socks);

Thanks Senthil for the reply.
I guess I dont need it by ref, the only thing I needed was to be able to use the same instance of that Socket, with it staying connected and usable while being passed to my C++ dll.
So would the C# part be a regular passing of the connected Socket?
for instance:
Socket socks;
ManagedMethod(socks);
and does passing it like this allow the C++ portion to use it without reconnecting and accepting of client?

I want to add a submenu to my programs context menu that will then show the standard Window's Explorer submenu.
Any ideas?
If anyone has ever used the program Tortoise CVS, it does such a thing. When you choose to Commit a set of files, right clicking on a file in the list displays the CVS menus, but there's also a submenu called Explorer. Highlighting this menu then displays a submenu just like you were in Window's Explorer and right clicked the file there.
help please..

Your best bet is to look into Windows Shell documentation and find out which Win32 calls (or possibly, Registry keys) can retrieve the list of Windows context menu options. That's the easy part. From there, you're gonna have to hook up your application to interop with the Windows shell; so that if you right click on some object in your program, it will allow you to, say, copy the file or text to the clipboard. That will be difficult.
I recommend you look for other options. What is it you want to do?

Hi,
I have a client application that I am writing that connects to a database (MySql) running a server on the network. I would like to be able to communicate from the server with any running client application to be able to send them messages (eg, the server is about to be rebooted, save your work now!). What would be the best way to go about this? I'm thinking that I could have my client listen using the TcpListener class to a port and write a quick and dirty app to run on my server that will use "show processlist" on the MySql server to find everybody who has a connection and send a message to them. Is this a good idea? I've never tried anything like this before.
Thanks
WJ

hi there,
below is just my idea:
1. write an server app on machine that MySQL is running on. this will listen on a port
2. ur client have to register itself to the server app after successfully connecting to MySql. So that the server app is able to know which clients are connecting to server
3. When the MySql is about to rebooted, just broadcast messages to all clients that are connecting to the server

Please anyone. How can I trap the delete key and handle it in such a way that the text in the richtext box will not be deleted.
thanks.

In your form, override ProcessCmdKey method. Then,
if(keyData == Keys.Delete)
{
return true;
}
