combo box selection

As you're asking the two questions together, I assume that the ComboBox contains the names of other Form classes in the same application and you want to load the selected Form.

Something similar to the following code should do it:

if (comboBox1.SelectedIndex > -1)

{

string formName = comboBox1.SelectedItem.ToString();

string nameSpace = "WindowsFormsApplication1";

Type t = Type.GetType(nameSpace + "." + formName);

Form f = Activator.CreateInstance(t) as Form;

if (f != null) f.Show();

}

"WindowsFormsApplication1" should be replaced with the actual namespace (as a string) that the forms are in - hopefully, the same one for them all.
