Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
 
        ComboBox1.Items.Add("4")
        ComboBox1.Items.Add("5")
        ComboBox1.Items.Add("6")
        ComboBox1.Items.Add("7")
        ComboBox1.Items.Add("8")
        ComboBox1.Items.Add("9")
        ComboBox1.Items.Add("10")
        ComoBox1.SelectedItem = 0
 
End Sub


Private Sub cmdShow_Click(sender As Object, e As EventArgs) Handles cmdShow.Click

Dim Message As string
Message = "Your items are " + ComboBox1.Text ... + vbCr
MsgBox(Message, vbOKOnly + vbInformation, "Your Items")

End sub

It shows an error in Message that "ComboBox1 is not declared. It may be inaccessible due to its protection level"

How can I display ComboBox1.Text..
I have many cboName.Text, but i put one for example.
Thank you!

search "Private WithEvents ComboBox1" in entire solution
replace with "Public WithEvents ComboBox1"
also search "Friend WithEvents ComboBox1"
replace with "Public WithEvents ComboBox1"
don't replace all, just ComboBox do you want to display

C#

private void Form1_Load(object sender, EventArgs e)
{

    comboBox1.Items.Add("4");
    comboBox1.Items.Add("5");
    comboBox1.Items.Add("6");
    comboBox1.Items.Add("7");
    comboBox1.Items.Add("8");
    comboBox1.Items.Add("9");
    comboBox1.Items.Add("10");

    // Please check your code their is spelling mistake Comobox1 and change to SelectedIndex to show 1st item in list
    comboBox1.SelectedIndex = 0;

}

private void button1_Click(object sender, EventArgs e)
{

    string Message = String.Format("Your Items are {0}\r\n", comboBox1.Text);

    MessageBox.Show(Message, "Your Item", MessageBoxButtons.OK);

}
