you can do it as the guys said. and Sergey is right the plain answer is NO.

However if what you're after is that the Form remains sizable in de Development environment even when you run the form. the suggestions of all guys won't help.

what I could suggest is that you test wether you're in Developmetn Environment or runtime. Thus your forms will remain sizable even if you run them if you're programming. and when you compile and build the exe when the user runs a form the form won't be sizable.

try this

*:Init method of the form
local llRuntime
llRuntime = Version(2) = 2

if llRuntime Then
    This.BorderStyle = 3
else 
    This.BorderStyle = 1
endif 

you won't be able to resize the forms when working at runtime (exe).

how about that
