Rem
If Len(Help$) <> 0 Then ' Double check help$
' Make sure help form is invisible:

' Change caption of label:
FrmHelp.Label1.Caption = Help$
' Get the cursor position so you can calculate where
' to place the help form:
Call GetCursorPos(lpPoint)
' Offset the form from the cursor by 18 and 2 pixels (values
' chosen to simulate the look of Microsoft Word version 6.0)
FrmHelp.Top = (lpPoint.Y + 18) * Screen.TwipsPerPixelY
FrmHelp.Left = (lpPoint.X - 2) * Screen.TwipsPerPixelY
' Adjust width of form to label + 4 because 2 are needed
' for each pixel of the border and 2 are needed to center
' the label (the label is inset by 1 pixel on the form).
' Also, adjust height of form to height of label + 2
' because 2 ar needed for each pixel of the border:
FrmHelp.Width = FrmHelp.Label1.Width + (4 * Screen.TwipsPerPixelX)
FrmHelp.Height = FrmHelp.Label1.Height + 2 * Screen.TwipsPerPixelY
' Make sure form is on top:
FrmHelp.ZOrder
' Show form without the focus:
ret = ShowWindow(FrmHelp.hwnd, SW_SHOWNOACTIVATE)

' Hide the form:
FrmHelp.Hide
