Hello NG,

I have a problem declaring a class member function using a template array of
same class:

What is your problem? It helps if you tell us what compiler error you get in
what line of code.

-------------------------------------
#include "TMyArrayClass.h"

class CMyClass
{
public: //...
bool search(const CMyClassArray& all);
};
typedef TMyArrayClass<CMyClass> CMyClassAray;
--------------------------------------

TMyArrayClass is a template class.

I tried pointers but no success. Do you know if there is a possibility to
declare my search-function?

My guess is that your porblem has nothing to do with templates but simply with
circular type dependencies?

Then you need a forward declaration:

-------------------------------------
#include "TMyArrayClass.h"

class CMyClass; // forward declaration to make the class name known

typedef TMyArrayClass<CMyClass> CMyClassAray;

class CMyClass
{
public: //...
bool search(const CMyClassArray& all);
};
--------------------------------------

Alternatively, you could declare the search function like this:

> bool search(const TMyArrayClass<CMyClass>& all);
