I have a xls template file that i have to fill with data.
2 of the fields in the template are =EMBED("Forms.ComboBox.1";"").
I never really saw this on a excel file and if i try to set a value to the cell where they are (apparently this controls are not in a cell) i get a null exception.
Has anyone ever changed the value of this controls with NPOI?
NOTE: The template is protected with a passwrod and only some cells are available. I don't and i won't be able to receive the password and i can't change the template file.
