When the form loads many objects such as cn, rs, ad, com, and reader, are also created in the program for uses and these objects occupy spaces in computer memory. When the form is closed these objects should be released from the memory.
Private Sub Dic_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
cn = Nothing
com = Nothing
ad = Nothing
reader = Nothing
Another thing we want to talk here is to let the user close the program when his/her clicks on the Close sub menu item form the File menu. This task can be done simply by attaching the following code to the Click event of the Close sub menu item:
Private Sub CloseToolStripMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CloseToolStripMenuItem1.Click
