Hi,
In my program with FWH32 7.10, oWnd:GetRect()[3] returns -8
in the new program with FWH64 16.04 Revd Build3 it is returning 1048.
Is there a difference between the version 7.10 & 16.04 or is there a difference between the 32bit and the 64bit version?
What is the correct one?
Marc,
Could you post an example of how you are using it ? thanks
.....
.....
ACTIVATE DIALOG oDlg CENTERED valid mbrowseexit() on init msize(oDlg,svGetlist,vWBreedte)
.....
RETURN
FUNCTION msize(oDlg,svGetlist,vWBreedte)
  local vhoogte  := oMenuWnd:nHeight - oDlg:nHeight - 8 -48
  vwbreedte = min(vwbreedte,oMenuWnd:nWidth-60)
  ........
  oDlg:nWidth  = vWBreedte + 68
  oDlg:move(oMenuWnd:nTop+4+24+oMenuWnd:GetRect()[2],(oMenuWnd:nWidth/2)-((vWBreedte+68)/2)+oMenuWnd:GetRect()[3])
  ........
RETURNMarc,
You can center a dialog (or any window or control) doing:
oDlg:Center()
to change the size fo a dialog (or any window or control) you can do:
oDlg:SetSize( nWidth, nHeight )
Thank you Antonio,
I was using this code since FW1.95, and never changed it because it was working fine 
oDlg:Center() and oDlg:SetSize( nWidth, nHeight ) is working fine with FWH64 16.04 Rev Build3 
Antonio,
This problem was solved with your solution, but now i found that I also use it in my programs, to know the location of the mail window, when closing the program.
I saved nPos[2] and nPos[3] of oMenuWnd:GetRect() to know the location, but now it is not OK anymore.
How can I get the location of the window, so I can restore it again while opening it?
Problem solved. 
Now I use nPos:nTop and nPos:nLeft, and it's working in the old FW and the new one.
I found that when using the array nPos, position 5 is nil in the old version, and not in the new version.
In the new version nPos[4] is equal to nPos[5] of the old version, and so on...
very good
