Floating Point Numbers Validation

Just like the title says, the code in the attached file will validate the floating point numbers in a text box.


Create a form with a textbox, and insert the following into the form code:

Private Sub Form_Load()

   Text1.Text = Empty

End Sub

Private Sub Text1_KeyPress(KeyAscii As Integer)

   ' Precision is 2 in this case
   ' Send the Precision Value same in both the Functions
   Call ValidateNum(Text1, 2, KeyAscii)

End Sub

Private Sub Text1_KeyUp(KeyCode As Integer, Shift As Integer)

   Call ValidateDel(Text1, 2, KeyCode)

End Sub
