Я пытаюсь создать форму и рамку в Delphi-made DLL, используя только ручки. Форма обычно появляется в приложении-хозяине, но кадр вообще не отображается.Delphi Form в DLL работает, но Delphi Frame - не
Что может быть неправильным?
Ниже я приведу кусок кода, который создает как Рама и окна:
library DLL1;
{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }

Где твое определение TDLLFrame1? – Dsm
Обновлено. Код тоже есть. – Paul
Как насчет DLLForm.pas? Как насчет образца кода, который вызывает CreateDLLForm и CreateDLLFrame? –
