Hi Matthew,
Compiling the program below with Visual C++ 8 gives an error.
In function set_data_or_deallocate_and_throw_ HANDLE (being deallocated) is
incompatible with the allocator's char* type.
Changing lines 269-271 from:
269 private:
270 template <ss_typename_param_k A>
271 void set_data_or_deallocate_and_throw_(UINT fmt, HANDLE hData, A&
ator) stlsoft_throw_1(clipboard_scope_exception)
to
269 private:
270 template <ss_typename_param_k C, ss_typename_param_k A>
271 void set_data_or_deallocate_and_throw_(UINT fmt, C* hData, A& ator)
stlsoft_throw_1(clipboard_scope_exception)
seems to solve the issue.
Cheers, Martin.
