Hi, thanks for your reply. I was not using boost:bind since I thought it must be bound to a pointer. The following line does the trick for me: boost::bind( &Object::setFieldImpl<T>, _1, fieldId, fieldData ); Regards, Jan ---------------------------------------------------------------------- Dipl.-Inform.

Hi everybody, I would like to bind a member function within the template function using the template argument. Please have a look at the following code:
template<typename T> void Object::setField(FieldId fieldId, const T& fieldData) { // call for_each with setFieldImpl ... shadowCopies->for_each ( boost::bind2nd( boost::mem_fun(&Object::setFieldImpl<T>), fieldId, fieldData))); }
template<typename T> void Object::setFieldImpl(FieldId fieldId, const T& fieldData) { ... do some stuff... }
bind2nd is soo last century... have you tried using boost::bind?
boost::bind( &Object::setFieldImpl<T>, fieldId, fieldData )
It is not guaranteed to work (MSVC 6 in particular might not be able to handle it), but it stands a better chance.
If that fails, you'd probably need to use
void (Object::*pmf)(FieldId, const T&) = &Object::setFieldImpl;
... boost::bind( pmf, fieldId, fieldData ) ...
