[Year 12 SofDev] vb.net error

Thank you Robert,
It certainly does make it confusing, especially when trying to teach normal AND/OR to students and then have to try and get into logical and/or issues like this ☺

Hello Damien
I don't know for sure, but having just wrestled with vb.net for the first time myself I understand some of your frustrations. Many vb settings are built up from vb 'bit constants' that are 'added' together to produce some overall effect.
In your case it might be, for example, that fontstyle.bold = "0001 0000' (or whatever) and fontstyle.italics = "0000 0100".
When you AND them, therefore, you get '0000 0000', whereas OR would produce '0001 0100', which I imagine would set both styles.

Just a guess at this stage. Hope it helps.

Hi folks,
            I’m just starting VB.Net with my year 11’s and have only ever used vb 6 before. The following code doesn’t make sense to me
I’m trying to just teach if else statements so using a couple of check boxes want the font in a textbox to change. In vb 6 you used to just say textbox1.fontbold=true and txtfontItalic = true not it seems totally different
[cid:image002.png at 01CB093B.E20F6010]
    Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
        Dim fnt As Font
        fnt = txtSomeWriting.Font
        If chkItalics.Checked = True And chkBold.Checked = True Then
            txtSomeWriting.Font = New Font(fnt.Name, 8, FontStyle.Bold Or FontStyle.Italic)
        ElseIf chkBold.Checked = True Then
            txtSomeWriting.Font = New Font(fnt.Name, 8, FontStyle.Bold)
        ElseIf chkItalics.Checked = True Then
            txtSomeWriting.Font = New Font(fnt.Name, 8, FontStyle.Italic)
        Else
            txtSomeWriting.Font = New Font(fnt.Name, 8, FontStyle.Regular)
        End If

    End Sub

I don’t get why it is only working if I have an OR between the 2 fontstyles, not an AND when I am trying to make the textbox Bold Italic

Does anyone have any ideas? Thanks in advance.
Regards
Damien
