If I understand you correctly, you want to stop Resize of the object during the first init of the form, resize the form and then allow controls resize. Is this right? If so because you build the form and add controls with code I suggested you in the init first to resize the form to its initial Height and Width and then add Achored controls. That way you don't need any flags.
Something like:

*** There where you add controls:
***  Set form original Height and Width
thisform.Height = 100
thisform.Width  = 200

*** Add controls
thisform.NewObject([MyAnc],[.....])
thisform.MyAnc.Left   = 0
....
** Resize the form to last user choice
