Я на Windows 10 Enterprise 64 бит с Excel 2016 Pro 64 бит.
Я пытаюсь добавить изображения в словарь Publi c, сначала вставив их в рабочую таблицу временной книги, а затем скопировав Shape в буфер обмена Windows, а затем удалив Shape из рабочей таблицы.
Код работает большую часть времени, но иногда возникают ошибки (не знаю причину)! Кроме того, при добавлении часов изображения отображаются в словаре как «ничего». Свойства IPicture показывают Application defined or object defined error.
Вопросы:
- Как мне решить эту проблему?
- Как загрузить изображения обратно из словаря в (текущую рабочую тетрадь) лист?

'* AUTHOR & DATE: STEPHEN BULLEN, Office Automation Ltd
'* 15 November 1998
'*
'* DESCRIPTION: Creates a standard Picture object from whatever is on the clipboard.
'* This object can then be assigned to (for example) and Image control
'* on a userform. The PastePicture function takes an optional argument of
'* the picture type - xlBitmap or xlPicture.
'*
'* The code requires a reference to the "OLE Automation" type library
'*
'* The code in this module has been derived from a number of sources
'* discovered on MSDN.
'*
'* To use it:
'* Set Image1.Picture = PastePicture(xlPicture)
'* to paste a picture of whatever is on the clipboard into a standard image control.
'*
'* PROCEDURES:
'* PastePicture The entry point for the routine
'* CreatePicture Private function to convert a bitmap or metafile handle to an OLE reference
'* fnOLEError Get the error text for an OLE error code
