Hallo Sergey,

thanks for the help. Now it works for TImages which are in the "main" editor.

The thing is: I would like to enable the user to resize the image controls

without having to set the caret to the image control's position. Thus I wouldn't

have to use ResizeCurrentControl, but ResizeControl, giving the correct item

number. As I wrote before, the FindControlItemNo works. If the image control

is in a table cell, I get the item no of the cell's inside editor. Thus I

assume that I have to call the cell's inside editor ResizeControl procedure.

But how do I do that? The cell's getRVData returns TCustomRVData, which doesn't

have a ResizeControl procedure.

Thanks for your help,
