Hi Karim,

I'd guess that there is something wrong in your project settings where a
library is getting loaded that isn't needed, or possible it's getting
included in more than one project. There may be a namespace problem as
well. You could look for instances of "using" and see if something is
getting dupliated. In the last case it looks like your class is NOT getting
included.

Usually these conversions go pretty well. There is likely something very
simple that will fix the errors...

hi Tom,
Thanks for ur reply.The Rebuild All has not solved my problem.If i comment
one of those two funtion declaration and defination.i am ok
compiler/linker.problem is when i used it with same namespace, class and
same
argument list.

Hi Karim,

It's tough to tell from your example, but I'd try recompiling all of the
lib's and the main code from scratch to see if the link errors get
resolved.
Looks like the other code change fixed your initial problem. I've found
that doing a Rebuild All can solve a lot of isuses as the later version
of
the compiler handles things a little differently. It's getting late and
the
example is a little difficult to read through, but it couldn't hurt to
try
the recompile.

Hi,

I'm moving my project from vc++6.0 to 2005 and i have some problems,
first
i
havecode in my .cpp like

========================================

BEGIN_MESSAGE_MAP(CSimCDMDispenseCP, CSimDialog)

//{{AFX_MSG_MAP(CSimCDMDispenseCP)

ON_WM_TIMER()

ON_WM_DESTROY()

ON_BN_CLICKED(ID_CDM_TAKE_CASH, OnTakeCash)

//}}AFX_MSG_MAP

ON_MESSAGE(PM_FIRSTDISPENSE, OnFirstDispense)

ON_MESSAGE(PM_NEXTDISPENSE, OnNextDispense)

END_MESSAGE_MAP()

===============================================

void CSimCDMDispenseCP:nFirstDispense(WPARAM, LPARAM)

{

.................

}

void CSimCDMDispenseCP:nNextDispense(WPARAM, LPARAM)

{

...............

}

=================================================

and in my header file code like

=================================================

afx_msg void OnFirstDispense(WPARAM wparam, LPARAM lparam);

afx_msg void OnNextDispense(WPARAM wparam, LPARAM lparam);

now the error i found with the above code is

==================================

Error C2440: 'static_cast' : cannot convert from 'void (__thiscall
CSimCDMDispenseCP::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::*

i googled for help and i found some info from the following links

now i changed the code in my cpp like
===============================================

{

.................

return 0L;

}

LRESULT CSimCDMDispenseCP:nNextDispense(WPARAM, LPARAM)

{

...............

return 0L;

}

=================================================

=================================================

and in my header file code like

=================================================

afx_msg LRESULT OnFirstDispense(WPARAM wparam, LPARAM lparam);
