Здравствуйте Lakmus, Вы писали:
L>Доброго времени суток!
L>У меня такой вопрос: как внедрить в свою диалог-форму стандартный диалог(например CFileDialog)?
Ну для разных диалогов, насколько я знаю, разные подходы. А для CFileDialog есть свой подход. Вот, для примера, код, который встраивает в CFileDialog превьюшное окно.
Сначала "вырезка" из ресурсов:
IDD_PREFIEW_FILE_DIALOG DIALOG DISCARDABLE 0, 0, 406, 144
STYLE WS_CHILD | WS_CLIPSIBLINGS
FONT 8, "MS Sans Serif"
BEGIN
GROUPBOX "",1119,0,0,290,144,NOT WS_VISIBLE
CONTROL "",IDC_PREVIEW_RECT,"Static",SS_BLACKFRAME,300,10,100,70
CONTROL "Preview",IDC_PREVIEW,"Button",BS_AUTOCHECKBOX |
WS_TABSTOP,300,85,41,10
END
Теперь к этому надо приляпать такой класс:
h:
#if !defined(AFX_PREVIEWFILEDIALOG_H__B7397C89_7459_417F_B8D3_4C24AC246490__INCLUDED_)
