working with time?

Morning,
IS there any way I can use a timer so that
1. when it reaches a certain time a message box will appear

2. between say 10:00 and 4:00 I could disable certain buttons on my form

You may be best not working with timers there icky and it will get confusing. You could use the system clock to determine the time, (assuming the user cant change these settings)

Here's a way to use the system time to do what you want down to the second. Start a project, put a label and a command button on it. The following code will display the current time in the label, disable the command button at the hour, minute and second you specify and then re-enable the command button 5 seconds later.

In the example shown, I had this stuff occur at exactly 10:43:00 AM. Obviously you can tinker to fit your needs.

VB Code:

Option Explicit
Dim showTime As Boolean
Dim MyHour As Integer
Dim MyMinute As Integer
Dim MySecond As Integer
Dim CurrHour As Integer
Dim CurrMinute As Integer
Dim CurrSecond As Integer
 
Private Sub DisplayTime()
Do While showTime = False
    Label1.Caption = Time
    DoEvents
    Check_Time
Loop
   
End Sub
 
Private Sub Form_Load()
    showTime = False
    Me.Show
    DisplayTime
End Sub
 
Private Sub Form_Unload(Cancel As Integer)
    showTime = True
End Sub
 
Private Sub Check_Time()
    ' Set hour, minute and seconds for alarm
    MyHour = 10
    MyMinute = 43
    MySecond = 0
    
    CurrHour = Hour(Time)
    CurrMinute = Minute(Time)
    CurrSecond = Second(Time)
    
    If (CurrHour = MyHour) And (CurrMinute = MyMinute) And (CurrSecond = MySecond) Then
        'MsgBox "Alarm !"
        Command1.Caption = "Stop"
        Command1.Enabled = False
    End If
 
    If (CurrHour = MyHour) And (CurrMinute = MyMinute) And (CurrSecond = MySecond + 5) Then
        'MsgBox "Alarm !"
        Command1.Caption = "Start"
        Command1.Enabled = True
    End If
 
End Sub

Thtas fine assuming the users canta djust the system clock.... Nice code by the way ;)

or you could do a

VB Code:

Private Sub Timer1_Timer()
text1.text = text1.text -1
End Sub
 
Form_load()
text1.text = 5
If text1.text <= 0 then
text2.text = Split(now)(1)
text1.text = 5
end sub

And then you could

If text1.text = 10:39 then 'or whatever
'blah

You might want to use => in case the second doesn't hit exactly at zero.
