hello there,
I would like to create a little function that can help me with pressing button many times..
for example if I press a button more than 5 times in 30 seconds to tell me "you cant press the button more than X times in less than X seconds"
how can I do something like that?

Hi,

You can use 2 variables to control that,

In your Form Declarations

Public intPressedTimes as Integer = 0
Public dteStartTime as Datetime

In you button  CLICK  event, add this code

If intPressedTimes = 0 Then 'is the first time the button is pressed or is another cycle
    dteStartTime = Datetime.Now  'Get the start Time of the first time the buttons was pressed
End if

If intPressedTimes > 5 Then 'Validates the Maximun Number of Time
  If (Datetime.Now - dteStartTime).TotalSeconds > 30 Then 'Validate the maximun number of seconds
      Msgbox("you cannot press the button more than 5 times in less than 30 seconds")
      Exit sub
  End if
Else
   'Finally reset the variable if the Seconds are more than 30 and the Pressed Times is not reach the   Maximum
   If (Datetime.Now - dteStartTime).TotalSeconds > 30 Then
      intPressedTimes = 0
   End if
End If

Hope that helps

Sorry one thing was missed, increment the intPressedTimes variable, here is the code of the CLICK event fixed

If intPressedTimes = 0 Then 'is the first time the button is pressed or is another cycle
    dteStartTime = Datetime.Now  'Get the start Time of the first time the buttons was pressed
End if

intPressedTimes += 1

If intPressedTimes > 5 Then 'Validates the Maximun Number of Time
  If (Datetime.Now - dteStartTime).TotalSeconds > 30 Then 'Validate the maximun number of seconds
      Msgbox("you cannot press the button more than 5 times in less than 30 seconds")
      Exit sub
  End if
Else
   'Finally reset the variable if the Seconds are more than 30 and the Pressed Times is not reach the   Maximum
   If (Datetime.Now - dteStartTime).TotalSeconds > 30 Then
      intPressedTimes = 0
   End if
End If

ok, do you want that the button can be pressend 5 times every 30 seconds? this will mean that in a minute, you can pressed 4 times from 1 to the second number 30 and then other 4 times from second 31 to 60, and only if you try to press more than 5 times each 30 seconds cycle the messages shows up?

Or do you want that if the button was pressed 4 times before 30 seconds, and then is pressed 2 more times since 30 seconds has pass already, it will show the message?
