vb program

[devonknows]

also one more question, how do i make it so if they put no value in the text box the program doesnt crash. i have it set so if they put a number above or below the array it gives a message box but if they do not put a number it crashes

you need to check if the value of text1.text doesnt equal "", the code below shows how to check if its null and then check the values of text1.text, of course as always change to your own.

Private Sub Command1_Click()
If Text1.Text <> "" Then
    If Text1.Text >= "1" And Text1.Text <= "10" Then
        MsgBox "Textbox has more than null value", vbInformation, "Info"
    Else
        MsgBox "Value has to be between or equal to 1 and 10.", vbInformation, "Info"
    End If
Else
  MsgBox "You need to input a value", vbCritical, "Error"
End If
End Sub

Hope this help,
kind Regards
Devon.
