Disable Button after one click user wise

Hi,

I've created a timesheet with user form for Login, Logout, Break start and End buttons. What am looking for is once a user clicks on any of the four buttons, the user should not be allowed to again click the same butotn on same day. This way i can stop overwrite data.

Request your help. Your immediate resolution will be highly appreciated

Attached is the protected worksheet and i've copied my macro for Login button.

Private Sub CommandButton1_Click()
'Your code here
CommandButton1.Enabled = False
'LOGIN BUTTON

Dim iHour As Integer, iMin As Integer, iSec As Integer

Cells(CurRow, "D") = Time
iHour = Hour(Now())
iMin = Minute(Now()) + 30
iSec = Second(Now())

'c.Value = TextBox1.Value ' write amendments to database
Cells(CurRow, "D").Value = Time

Label1.Caption = ""
TextBox1.Value = ""
TextBox1.SetFocus
End Sub

Please keep in mind that forum rules require you to post your code in code tags. Please edit your post and put the VBA code part of your code between code tags.

I think your best bet is to disable the button once there is any text in the corresponding cell. To specify, instead of disabling a button after it's clicked, check the cell to see if there is any text once the button is clicked.

If you need additional help, please post a copy of your workbook with the VBA project unlocked
