Two errors I need help with.

15y14.4k.NET

Error1:

  foreach (System.Windows.Forms.Button b in this.Controls)
                             {
                                 b.Image = WindowsApp1.Properties.Resources.BtnImg;
                               }

Unable to cast object of type 'System.Windows.Forms.GroupBox' to type 'System.Windows.Forms.Button'.

Error2:

String temp = ListBox1.Items[0].ToString

Cannot convert method group 'ToString' to non-delegate type 'string'. Did you intend to invoke the method?

You need a new loop
foreach (Control b in groupBox1.Controls)
{
if (b is Button)
{
b.BackgroundImage = ArrayCompare.Properties.Resources.BtnImg;
}
}

How come:
foreach (Control b in this.Controls & GroupBox1.Controls)
doesn't work?

foreach (Control b in this.Controls)
{
if (b is Button)
{
b.BackgroundImage = WindowsApp1.Properties.Resources.BtnImg;
}

}
string temp = listbox1.SelectedItem.ToString();
