There are problem with the sendkey method, you api:

Add this declaration on top of your mdiform code
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

Change this sub

Private Sub mnHelpManual_Click()
'    SendKeys ("{F1}")
    keybd_event 112, 0, 0, 0
    keybd_event 112, 0, &H2, 0
End Sub

I have test it out and it works fine at my computer.

Thanks

[01]
after user have run the application, then close the product view THEN

AND straight away click the help
OR   click "delete order" button
OR   click "my profile" button
THEN
   click help button OR "F1"
   the help file doesnt show straight away, user will have to click on the help button again
   then only shows the help file
END IF

[03]
IF
login as admin
AND straight away click the help
OR   click "customer maintenance" all sub buttons
OR   click "ordermaintenance > new order & delete order" button
OR   click "product maintenance" all sub buttons

Donn't use keybd_event, try to open the chm directly,

add this line to the top of the code
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

add this line
Private Sub mnHelpManual_Click()
    Dim ret As Long
    ret = ShellExecute(Me.hwnd, vbNullString, App.HelpFile, vbNullString, App.Path, 1)
end sub

Thanks,
