Its saying Class isn't defined any ideas why?

[voidflux]

Hello everyone, Okay with the help of some IRC people I figured out my code has circular dependancey, so i had to use forward headers.

I'm getting an error saying:

1>EmailSubdomain.h(25) : error C2079: 'EmailSubdomain::Domains' uses undefined class 'EmailDomain'
1>EmailDomain.h(9) : fatal error C1083: Cannot open include file: 'EmailSubdomain': No such file or directory
1>EmailTld.cpp

Here is my EmailSubdomain.h

//file:		EmailSubdomain.h
//Code by:	Cory Sanchez




#pragma once



#include "EmailDomain.h"
#include <string>

class EmailDomain;


class EmailSubdomain
{
   public:
      EmailSubdomain()
	  {
		  Name = "";
	  }
   
   public:
	   EmailDomain Domains;
	   std::string Name;

   public:
       bool IsValid(); 
 
};

And here is my EmailDomain.h

/file:		EmailDomain.h
//Code by:	Cory Sanchez

#pragma once

class EmailSubdomain;

#include "EmailTld.h"
#include "EmailSubdomain"



#define MAX_SUBDOMAINS 10
#include <string>

class EmailDomain
{
   public:
      EmailDomain()
      {
          SubdomainCount = 0;
		  Name = "";
      }
   
   public:
	  std::string Name;
	  EmailTld Tld;
      EmailSubdomain Subdomain;
      int SubdomainCount;


   public:
      bool Parse();
      bool IsValid();    
	  int GetLengthSubdomain(const char *text, int startPos, char aChar);
};

Any ideas what i'm not doing right?

Maybe i'm making this more complicated than it needs to be but what my main goal is this:

I have an Address passed into a Email object like this

Email email("[email protected]");

This will then get parsed in a member function of Email.h.
Email.h has 2 objects of another class EmailLocal.h and EmailDomain.h

I assign the Local Part of the address to EmailLocalPart.UserName =
I assign the Domain part of the addresss to EmailDomain.UserName =

Now There is also a TLD part of this e-mail:
[email protected]
"edu" is the TLD.
I parse out the TLD part from passing the EmailDomain.UserName to the class Domain.h which also has a Parse() function that will assign
EmailTld Tld.Name = tld;

But for me to do this I have to create make a data member in EmailDomain.h of type EmailTld, which is also a class. I don't see why this is illegal.

ANy help would be great.

Its also saying no such file as EmailTld.cpp but here's the code here right:

//EmailTld.cpp
#include "EmailTld.h"



bool EamilTld::IsValid() const
	{
		if(Subdomain.IsVald() ) 
		{
			return true;
		}
		else
			return false;

	}

Also here is the heder for EmailTld.h

//file:		EmailTld.h
//Code by:	Cory Sanchez


#pragma once

#include "EmailSubdomain.h"
// Subdomain and Tld are identical, except for
// slight differences in validation rules, so to avoid repetition derive EmailTld class from EmailSubdomain base class

class EmailTld: public EmailSubdomain // EmailTld class is derived from
	
{
public:
	EmailTld();
	EmailSubdomain Subdomain;	

public:
	virtual bool IsValid(); 
};

You have no file called "EmailSubdomain", yet you're trying to include it. Also, your classes have a recursive inclusion dependency, which is not possible.

Thanks CornedBee my design was really screwed up!
Do I have any recrusive inclusion now?

For some reason i'm still getting an odd error though that says:

\EmailDomain.h(27) : error C2146: syntax error : missing ';' before identifier 'Tld'
1>EmailDomain.h(27) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

I fixed that problem by commenting out the EmailTld.cpp file, but now I'm back to my orginal error yay! but this one i think can be fixed easily but i'm not sure where

Hm....I seemed to resolved the problem by commenting out the EmailTld.cpp file, but now i'm getting the following:

EmailTld.h(13) : error C2504: 'EmailSubdomain' : base class undefined

I don't see a cause for this error now.

[voidflux]

I got it working!!!!

It was quite strange, I had a few typos, and also I forgot to include somthing in the base class, thanks for the help though it made me realize how messed up my mind set was at the time!
