What can we do to usign WTL in dll?

Alain Rist wrote:

WTL is a template library and as you certainly know templates are compiled when used, not when declared. Thus it is impossible to export uninstanciated template classes from a dll.

That said, you can use WTL in dlls which export only fully instanciated templates like WTL_DLL.ZIP in the Files section of the WTL support list[^].

Another example is here[^].

extern "C" __declspec(dllexport) void ShowDlg()
{
    CDialog dlg(IDD_Dialog1);
    dlg.DoModal();
}

Why "FlatSB" is useless in WTL?
