Welcome Giuseppe
unfortunalty there isn't a predefined way to do this, so you have to check every single input if it is a digit or not.
try the following:
1. make a new form with an editbox
2. add the event OnChange for the editbox
3. switch to code view ('view project source' icon)
4: insert this code in the OnChange function:

PHP Code:

text$=Edit1.text;
length$=length(text$);
lastchar$=chr(text$[length$-1]);
if(isdigit(lastchar$)==False)
 Edit1.text=mid(text$,0, length$-1 );
end; 


now you can add another if-loop for the comma.
you can also insert this code per visual programming, but this way its a bit faster.

You could also create a new component inherited from PEdit and just add ES_NUMBER to the PEdit.Create proc.

[Nicknack]

that is even a better solution, have overlooked this editbox style

Pls can You post an example on how to inherit form PEdit and how to right align text?

Regards,

ES_RIGHT should be the adequate style. concerning inherting, simply inherit the PEdit class and copy/rewrite the create function to your needs. see the help file topic about classes for further info.
