This trick is really quite simple requiring only 3 lines of codes involving GetWindowLong and SetWindowLong. I just added some codes to show how it looks like. See if this can come handy to you:
loTest = Createobject("Form1")
Define Class form1 As Form
AutoCenter = .T.
Caption = 'ControlBox on Left side'
ShowWindow = 2
Add Object label1 As Label With ;
top = 20,;
left = 10,;
FontSize = 16,;
width = Thisform.Width -20,;
height = Thisform.Height - 20,;
WordWrap = .T.,;
Caption = "This shows how to reverse the title bar's OBJECT positions such as "+;
"controlbox, icon and labels while leaving the inside of the form on normal left to right positions"
Declare Integer SetWindowLong In user32 Integer HWnd, Integer nIndex, Integer dwNewLong
Declare Integer GetWindowLong In user32 Integer HWnd, Integer nIndex
SetWindowLong(Thisform.HWnd, -20, Bitor(GetWindowLong(Thisform.HWnd, -16), 0x80000))
