Its saying Class isn't defined any ideas why?
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:
Code:
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
Code:
//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
Code:
/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:
Code:
//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
Code:
//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();
};
Re: Its saying Class isn't defined any ideas why?
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.
Re: Its saying Class isn't defined any ideas why?
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:
Code:
\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
[code]
Hm....I seemed to resolved the problem by commenting out the EmailTld.cpp file, but now i'm getting the following:
Code:
EmailTld.h(13) : error C2504: 'EmailSubdomain' : base class undefined

// Address property of type String

I don't see a cause for this error now.
Re: Its saying Class isn't defined any ideas why?
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!
