Thanks Erel,

I've already been there twice, I seem to be missing something. It gives promise of doing what I want but lacks details for the uninitiated.

Regards Roger

Something like:

B4X:

IME.SetCustomFilter(EditText3, EditText3.INPUT_TYPE_TEXT, "0123456789_ABCDEFGHIJKLMNOPQRSTUVWXYZ")

Do note that it is the responsibility of the soft keyboard app to respect this filter. So your app should expect invalid inputs as well.

Ah! The light bulb has turned on.

Thanks Erel,

Now that I can see it, I can't understand why I couldn't see it before.

Regards Roger
