Sergey,

How to determine which calls in commctrl need to be changed:
parameters must put between () s ?

I have a lot of code which works using set udfparms to reference.
I'm unable to re-write and test this amount of code.

So I need to change the commctrls so that this will work also
with set udfparms to reference setting.

>The problem is caused by set udfparms to reference. See http://fox.wikis.com/wc.dll?Wiki~SetUDFParms~VFP why you shouldn't change this setting in first place.
