Set id to auto-increment, and delete $ data ['id'] = "$ id.2: $ oline = M ("Oline ");$ Data ["id"] = "$ id ";$ Data ["to"] = "$ ";$ Data ["time"] = "$ t ";$ Data ["ip"] = "$ _ ip ";$ Oline-> add ($ data );

MyBase keywordYou can use the MyBase keyword from any subclass to call any attribute or method in the base class. You can use this keyword to call a base class method even if the method of the base class has been overwritten in the subclass. For example, if there is a ReplaceAll method in the base class, but this method has been overwritten in the subclass, you can call the ReplaceAll method of the base class from the ReplaceAll method of the subclass. Try opening the frmLineTest. vb form.Double
