I have two forms frmMAin and frmWrong,
frmMain has 2 textboxes named

txtinput1 and txtinput2
a label with "+" in between them.
and a "=" at the end of them
and chackbox named chkanswer

frmWrong has 1 textbox on it  
named txtanswer

now how do I hide the frmMain and display the frmWrong with appropriate answer then hide it and display the main form after a certain length of time?  

Thank you, John

you could just use the msgbox function if frmWrong doesn't have much to display.  Something like this:

Private Sub Command1_Click()
    MsgBox "Incorrect answer." & vbCrLf & "The correct answer is: " & (CDbl(Text1) + CDbl(Text2))
End Sub

'Put this code in frmMain:


Function GetNewTime(Number As Integer, IntervalType As String)
    'Intervals are the same as in the DateAdd function
    'yyyy Year
    'q Quarter
    'm Month
    'y Day of year
    'd Day
    'w Weekday
    'ww Week
    'h Hour
    'n Minute
    's Second
  Dim FirstDateAndTime As Date
  FirstDateAndTime = Date + Time
  GetNewTime = DateAdd(IntervalType, Number, FirstDateAndTime)
End Function

Function WaitTill(NewTime)
  Dim CurrentDateAndTime
  CurrentDateAndTime = Date + Time
  Do While CurrentDateAndTime < NewTime
    DoEvents
    Let CurrentDateAndTime = Date + Time
    DoEvents
  Loop
End Function



Private Sub Command1_Click()
    frmWrong.txtAnswer.Text = CDbl(Text1) + CDbl(Text2)
    frmWrong.Show
    WaitTill (GetNewTime(5, "s"))  'pauses for 5 seconds
    frmWrong.Hide
End Sub

You could also do the same thing using a timer control:


Private Sub Command1_Click()
    frmWrong.txtAnswer.Text = CDbl(Text1) + CDbl(Text2)
    frmWrong.Show
    Timer1.Interval = 5000
    Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
    Timer1.Enabled = False
    frmWrong.Hide
End Sub

    frmWrong.txtAnswer.Text = CDbl(Text1) + CDbl(Text2)
    frmWrong.Show
   
    Dim NewTime As Date
    NewTime = DateAdd("s", 5, Date + Time)

    Do While NewTime > Date + Time
        DoEvents
    Loop
   
    frmWrong.Hide
End Sub
