To limit combo height increasing I know IntegralHeight boolean prop, if you set it to False, your combo height won't be changed. Regarding the width I haven't got any solution. Maybe someone else at the forum could help you.

To avoid proportionnal font problems , fill your items with autosizing string :

cbo.AddItem el(1) & Space$(10 - el(2)) & el(2)

This works fine as far as length of el(2) is < to 10 (to avoid error message Incorrect Procedure Call)

Bye
