Hello!,

How I can limit textbox (or combo) from accepting only numbers and
Minimum is zero and maximum is Number of days in a specific month?

say for eg. In comboBox1 i select february then textBox1 shoul accept
only from 0 to 28 or in case of april 0 to 30, May 0 to 31 etc...

based on the value in textbox1 textbox2 is calculated, so textbox1
should not be allowed to be empty to avoid an error

thanks

The simplest way for beginners is to validate the data once it is
entered.
Private Sub TextBox1_Change()
t = TextBox1.Text
If Not IsNumeric(t) Then MsgBox "Non numeric character "
End Sub

For experts, each keystroke can be monitored.
