why ???

You should understand from the error log that oBrwLook is nil.
Again you yourself should figure out why this variable contains NIL but not a browse object, verifying your code.
Others can not help.

If I put this line

Code: Select all  Expand view

 DEFINE BUTTON OF oBar RESOURCE "LOOK_COMBO"  MENU Menulooktab(oBrw)

then the command

Code: Select all  Expand view

:CreateFromCode()
         END
 

run ok
