Example:

' Display the text "Hello, world!" on window Form1 at (100,50).
' Center the text horizontally at that point and have it appear below the point.
Dim retval As Long  ' return value

' Set the reference point to be centered horizontally and on the top edge of the text:
retval = SetTextAlign(Form1.hDC, TA_CENTER Or TA_TOP Or TA_NOUPDATECP)
' Display the text:
retval = TextOut(Form1.hDC, 100, 50, "Hello, world!", 13)
