[RESOLVED] How to close a form in 30 seconds?

Dear Sir,

When I open a form it should close automatically in 30 seconds. How can I do this using Timer? What is the code? Please help.

Regards,

Margaret

Just set the timer's interval to 1000 (1 second), then every time the timer ticks, add 1 to a global variable. When it reaches 30, close the program.

VB Code:

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
 
Private Sub Form_Load()
Sleep 30000
Unload Me
End Sub

Or set the timer's interval to 30000 (30 seconds) then when timer ticks, close the program.

Option 1

VB Code:

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private StopSleep As Boolean
Private Sub Form_Load()
Me.Show
Dim i As Long
For i = 1 To 30000
If StopSleep Then Exit For
Sleep 1
DoEvents
Next i
End Sub
Private Sub Form_Unload(Cancel As Integer)
StopSleep = True
End Sub

Option 2
Set the interval to 30000

Option 3
If you want it really long (eg. 20 minutes), you can workaround this with a second timer, set the interval to 1000

VB Code:

Private Sub Timer1_Timer()
Static i As Long
i = i + 1
If i = 30 Then Unload Me
End Sub
