Help!! please

Hi,
I just started programming in VB .NET, well actually i just started programming, in fact i'm in a intro to programming class currently and our Instructor likes to play tricks on us, like not helping us. Hence the reason i'm posting here, our project is to make a Greeting card program, i've got it finished for the most part, but there are a few bugs, and one thing i have no clue how to start.

download the project here

sorry about the size, it's 1.4mb btw

- The change holiday button needs to display each holiday group box, one at a time, i'm not sure how to do this, i know to how to make the group boxes invisible (Visible:False), but i don't know how to make them appear again.

- My text style check boxes work, but when you check more than one it does'nt apply the other formatting.

- Full screen button doesn't work right, i think there's something wrong with the code.

I know this is about 5 minutes of work for a seasoned programmer, but I've seriously spent hours trying to figure this out.

Thanks for any help

Here's the first problem solved:
The code u used will maximize the form, and then execute directly the Minimize code again becose u used twice the If statement...
Use Else

This is how it should be:

VB Code:

Private Sub btnFullScreen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFullScreen.Click
        If (WindowState = FormWindowState.Normal) Then
            WindowState = FormWindowState.Maximized
            btnFullScreen.Text = "Minimized"
        Else
            WindowState = FormWindowState.Normal
            btnFullScreen.Text = "Full Screen"
        End If
    End Sub

Check out the VBCodeBook.NET for ready-to-use drop-in code, there might be something useful there!

:D

i still haven't found anything on the group boxes though. I just need one holiday group to appear everytime the change holiday button is pressed.

EDIT: Figured out group boxes, thanks everyone for your help
