Hello you Gurus and other exell programming addicts

I've created a program under vba exell that has been working fine on my
computer for nearly a year. Now, some colleagues are starting to use this
program aswell but on some stations VBA does not recognise the
commondialog1. function altough all station ahave been configured in the
same way by our lan manager...
I've checked in the references and there is a box checked with says :

|v| MISSING:Microsoft common dialog control 6.0

where on my computer and other recognising the function it is stated

|v| Microsoft common dialog control 6.0

does anyone know a way around this problem?



Something else now :

Is there a way to avoid that the close button (top right corner X) appears
in my userforms. I've included a dedicated button in every form that closes
the form but also does other things before doing so and I want the user to
use that (and only that) button to close the form.

Hoping I've been clear enough (...probably not) I'm waiting for any
suggestion.

Greetings from Brussels,

Didier
