Have you tried gethostbyname()?

How, or why, are you distinguishing between "Internet" and "internal?"

Actually, i got a requirement, where i have to get the IPaddress of the system and also its local IP address if it is connnected with in a lan.
and i mean the local ipaddress is the internal ipaddress.
For example my system IPaddress are
E.g : Internet IPaddress : 219.91.165.43
Internal IPaddress : 192.168.0.9
how to get them

Are you sure this isn't the address of some firewall or gateway? Is the name of your machine 43-165.91.219.static.iqara.net?

The "internal" ip of the remote system is useless from the outside anyway.
If you MUST have it you can have the server send it to you when you connect.

I understand what you want. You can't get it from outside the LAN. Maybe there's a way to
hack in to the router LOL. I would hope not.
Have your server (behind
the NAT) call gethostname(). That will give you the local (LAN) ip address. Send that address to your
client outside (on the WAN).
Call getpeername() from the client to get the server's public (WAN) ip address.

Not much you can do with that address from outside the LAN except display it.
Why the requirement? If you can be a little more specific maybe there's a solution.

Hello, I have to fill a parameter from an edit box, which is later used when creating an sql statement.
Are there any special characters in addition to "*" which I may not use ?
And is there any possibility to easyly avoid that a user enters a "*" into the edit box ?
Greetings

That would be up to the application requirements. You may want to limit it to just letters, or numbers, or both. You may want to include a few special characters.

By deriving a class from CEdit and overriding the OnChar() method, you can allow/reject whatever character you choose.

You probably want to look in the articles section of the site, there's bound to be plenty of examples there, you can probably find one that does what you want and just use it.

Also, you may want to look for articles on avoiding SQL injection.
You don't want users(hackers) to be able to enter SQL statements that get combined with
your embedded statements.

Apostrophe can cause problems too

So what's not working? When you step through the code using the debugger, what are you seeing?

Have you tried entering this SQL statement in the DB console and looking at the results to see if there are actually any?

And that matters how? Just use a string literal (equal to whatever sTextDatabase would otherwise contain at runtime) in the DB console. Quite making this overly complicated.

What's not to understand? Do you know how to use a SQL statement in the DB console?
