initialize the pointer structure

[SM]

Hi,
I have ATL project in VS2008.
I'm trying to initialize the structure as below in the header
file(test.h)
#pragma once

#include "resource.h" // main symbols

#include <atlhost.h>

typedef struct{
int a;
int b;
}TestStructure;
class CTestStructureDialog :
public CAxDialogImpl<CTestStructureDialog>
{
public:
TestStructure *t2={0,1}
};
I'm getting error as below
error C2059: syntax error : '{'
error C2334: unexpected token(s) preceding '{'; skipping apparent
function body
How to initialize the pointer structure?

When i initialise at .cpp file using t2=new TestStructure, it's
working fine, how i can assign default values in new TestStructure

When I tried without initialize and refer the structure in another
class,
Class name :CTest1(file test1.h)
class CTest1 :
public CAxDialogImpl<CTest1>, public CUpdateUI<CTest1>,
public CMessageFilter, public CIdleHandler
{
public:
TestStructure t3; // getting error in this line error C2146: syntax
error : missing ';' before identifier

};
I'm getting error as
error C2146: syntax error : missing ';' before identifier.
The actual code is converted from VC++6.0 to VS2008 using project
conversion wizard in VS2008.




Thanks,
Sony

struct TestStructure { ... };

Drop the 'typedef' to assign a typename to an anonymous structure.

How to initialize the pointer structure?

Two things:
1. You can only initialise a pointer to a pointer value, while you are
giving two integers here to (probably) initialise what the pointer points
to. You probably don't want a pointer. As a general rule, don't use
pointers.
2. Initialise things in the constructor's "initialiser list", which should
be explained in every C++ book. Note though that you can't initialise an
aggregate like TestStructure unless it has a constructor itself.

^^^^^^^^^^^^^

Shouldn't that be CAfxDialogImpl? If so, please reconsider whether you want
to cut'n'paste so that people know what your code is or retype things so
people have to guess. Also, in C++ the compiler doesn't care where (in what
kind of file) code is written, so it doesn't matter that you did something
in a .cpp file.

This used to compile in VC6 but doesn't in VS2008?

That was understood, what about the other questions?
