I am trying to find out if i can tell if a form is opened. I tried if palettef.showing then,
if palettef.enabled then ,
if palettef.active then

But i get an error if the palettef form is not opened.
Anybosy got an idea?
Thanks.

check if form is created:
if form2 = nil then
do something...

check if form is visible:
if form2.visible then
do something...

Thanks man. I was missing the nil...I did change it to if form2<>nil to find out if it was created.

Standard check if you work with on the fly objects:

if Assigned(Object) then
 DoSomethingWith(Object)

so in your case:

if Assigned(Form2) then
 if Form2.Visible then 
   ...
