Text not all displayed by the time new form has been created

Text not all displayed by the time new form has been created

i built a program by using c#, and i wanted to make a new form (like
microsoft word, excel etc), and i already can achieve it, however, the
text are not all displayed by the time i command to create a new form.
Here is the image before new form created:
And here is the image after new form created:
I was wondering, why the text and the menu "File" not displayed after i
create a new form? i already called this function that contains all the
text and the textboxes, but only textboxes that come out:
private void AddObjects(object sender, EventArgs e, Form theForm)
{
textBoxQuantityContainer = new List<NumericUpDown>();
textBoxCodeContainer = new List<TextBox>();
textBoxDescContainer = new List<TextBox>();
textBoxSubTotalContainer = new List<TextBox>();
textBoxTotalContainer = new List<TextBox>();
textBoxAllTotalContainer = new TextBox();
OleDbDataReader dReader;
OleDbConnection conn = new OleDbConnection(connectionString);
conn.Open();
OleDbCommand cmd = new OleDbCommand("SELECT [Code] FROM
[Data]", conn);
dReader = cmd.ExecuteReader();
AutoCompleteStringCollection codesCollection = new
AutoCompleteStringCollection();
while (dReader.Read())
{
string numString = dReader[0].ToString().PadLeft(4, '0');
codesCollection.Add(numString);
}
dReader.Close();
conn.Close();
if (firstForm.comboBox1.SelectedIndex == 0)
{
label1.Text = "Code:";
label1.Location = new Point(60, 125);
label2.Text = "Welcome to the Selling System.";
label2.Location = new Point(600, 30);
label3.Text = "Quantity:";
label3.Location = new Point(155, 125);
label4.Text = "Description:";
label4.Location = new Point(580, 125);
label5.Text = "Sub Total on Rp:";
label5.Location = new Point(1020, 125);
label6.Text = "Total on Rp:";
label6.Location = new Point(1210, 125);
label7.Text = "Total on Rp:";
label7.Location = new Point(1080, 580);
}
else if (firstForm.comboBox1.SelectedIndex == 1)
{
label1.Text = "Kode:";
label1.Location = new Point(60, 125);
label2.Text = "Selamat datang di Selling System.";
label2.Location = new Point(600, 30);
label3.Text = "Banyaknya:";
label3.Location = new Point(145, 125);
label4.Text = "Keterangan:";
label4.Location = new Point(580, 125);
