So i am trying to store my main form and open a new one however i get this error, here is the code:
I have this at form level
public static frmAddBook frmkeepBooks = null;
public frmMain()
{
InitializeComponent();
frmkeepBooks = this;
}
Cannot inplicitly convert type Books.frmMain to Books.frmAddBook
Change the first line into:
public static frmMain frmkeepBooks = null;
The types should be equal (or in herited) and probably it is not.
