HI

I have some problem in VC++ can any one help in resolving it

the follwing is the code

class ClassA
{

...........

}

In ClassA.h i wrote

void fun1();
void fun2();

in ClassB.h i declared a pointer object to ClassA like the following

ClassA *obj;

class ClassB
{
void fun3()
{
obj=new ClassB();
obj.fun1();// here the error is fun1() must have class/stuct/union type.

}
}

and one more thing

when we right click on the class name in the popup menu there will be a option like " go to Definition of <class name>" when we click this it should take to class definition. but instead it is giving me a error message saying " the symbol <class name> is undefined"

please kindly help me in this regard

u can mail me to the email -id "t_niru82@yahoo.com" also

thanks in advance

It means, Visual Studio can't find this class, may be you didn't add class.h file to your solution.

sometimes ncb file be broken. try to delete it, Visual Studio recreate it after first run.

ClassB member obj is a pointer to a ClassA object. You need to use the following code:

obj->fun1()
