Виртуальная клавиатура или как вставить символ в чужое приложение

[alex_stp]

Здравствуйте. Пишу приложение виртуальная клавиатура на winapi используя только цифры от 0 до 9. hwnd компонента по которому кликнула левая кнопка мыши отловить получается, но нему понять как напечатать символ в этом компоненте. функция SetWindowText не помогает. может подскажите ещё варианты?

Заранее благодарю за ответы.
