Aaron -

There are a number of reasons this will happen, so I can't tell you why it
happened. Usually this happens because some code you wrote created an error
condition that would not allow the form design to complete.

I can tell you how to fix it without starting all over, however. In the
code for the form, check the mysterious "Windows Form Designer generated
code" region...

It normally looks something like this:

Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    'Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer

    'NOTE: The following procedure is required by the Windows Form Designer
    'It can be modified using the Windows Form Designer.
    'Do not modify it using the code editor.
    Friend WithEvents TextBox1 As System.Windows.Forms.TextBox
    <System.Diagnostics.DebuggerStepThrough()> Private Sub
InitializeComponent()
        Me.TextBox1 = New System.Windows.Forms.TextBox
        Me.SuspendLayout()
        '
        'TextBox1
        '
        Me.TextBox1.Location = New System.Drawing.Point(0, 0)
        Me.TextBox1.Name = "TextBox1"
        Me.TextBox1.TabIndex = 0
        Me.TextBox1.Text = "TextBox1"
        '
        'Form2
        '
        Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
        Me.ClientSize = New System.Drawing.Size(568, 421)
        Me.Controls.Add(Me.TextBox1)
        Me.Name = "Form2"
        Me.ResumeLayout(False)

    End Sub

#End Region

What usually is missing is the line(s) in the InitializeComponent section
thats sets your control objects to new instances of the control:

     "Me.TextBox1 = New System.Windows.Forms.TextBox"

OR the line(s) that add the control(s) to the form's control collection are
missing:

     "Me.Controls.Add(Me.TextBox1)"

Just figure out what is missing, and type it in, and you should be good to go!
