vb.net - How to cancel keypress action in VB?

Question

This my code for validating empty fields. The purpose of the click is to save the details entered by the person. But the problem is the code to cancel the keypress when the user did not meet the conditions.
The SAVE button should not take me to the file location but instead ask me to re enter details to validate. Can someone help me?

If creditcard = "" Or name = "" Or streetname = "" Or town = "" Or postcode = "" Or housenumber = "" Then
    cmdPrintReceipt.Enabled = False
    MsgBox("Please leave no blank fields", vbCritical)
Else
    savefiledialogPersonalDetails.ShowDialog()

    Dim location As String
    location = savefiledialogPersonalDetails.FileName

    My.Computer.FileSystem.WriteAllText(location & ".txt", "" & lblReceipt.Text, True)

    cmdPrintReceipt.Enabled = True

    lblReceipt.Text = lblReceipt.Text & " CUSTOMER  " & name & vbCr
    lblReceipt.Text = lblReceipt.Text & " THANK YOU " & name & "YOUR PURCHASE, HOPE TO SEE YOU SOON!!! " & vbCr
End If
