Hi,
I dont know what is your windows service doing. But I have an idea.
You can take care of this.
The idea is that your windows service program should populate a broadcast message in your network for every time intervals. In that broadcast message you can specify your default message that includes ip address, etc.,
In your winsock program , you could receive that default message. The default message might have an IP address of the host machine.
Using this you can achive your way.

thanks

Make the constructor of the base class private. If you inherits a class from this base class, you'll get a compile error saying that it cannot access the constructor of the base class.

 Are you sure your question is correct ? So, you want to have at least one instance of your class ? You can simply declare a static instance in the cpp file of your class but I doubt this is the answer you are looking for.

You just want one instance of a class or more than one.(You are already allowed to create as many instances of your class as you wish)
If you say that you only want to let the user create a single instance of your class then you should use a static variable in your class. Increment that variable in the constructor if first object is being created. Now when second object would be created check for the value of the static variable to be greater than 1(or something that you work out), if affirmative just return from the contructor. This won't let the user create a second instance of your class.
You can also search for other methods here on CP for the SingletonClass.
Somethings seem HARD to do, until we know how to do them.

1) So what? You can check for the value of the static variable to be zero and return from the constructor.
2) If your question pertains to objects you can also create an abstract class.You can't create an object of the abstract class. To create a abstract class just add one pure virtual function to your class definition.

Does anybody have any experience with the squirrel scripting library? I have already posted my question on their forums but they look a little inactive.
I'm trying to pass a struct by reference to a script but I am unable to find any example of how to do this.

Can some one suggest some C++ API or code snipper to check if a TIFF file is compressed using G4 compression.

Check the compression field in the header. The following values are possible:
Uncompressed 1
CCITT 1D 2
Group 3 Fax 3
Group 4 Fax 4
LZW 5
JPEG 6
PackBits 32773
Have a look at the LibTiff library.
I found the spec at http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf[^]
