I try to open an excel sheet embedded in OLE container on a form. The sheets are usually larger than container itself, but I cannot enlarge it, so I need to contract those sheets. If i try to change dimensions of displayed sheet via width and height property (for example, application.excel.workbooks(i).windows(i).Width = number), error 'property cannot be set' is raised. So, how to resize it anyway?
Thank for advice
