how to do to know if a form is open,

[Wilton Ergon]

how to do to know if a form is open, the command below, performs the show in the form, in vcl this behavior be very different,

 

if form = nil then // this runs a show    showmessage ('form is nil')

 

when I close one form and open another, the previous form still displays on the screen.

 

sample:

 

form1.showmodal;   //form freeonclose =true

form2.showmodal;  //form freeonclose =true

 

when it closes form1, and it shows form2, form1 still shows on the screen
