IPComboBox OCX gives the programmer the ability to add IP address entry to applications easily. The IPComboBox restricts the user to entering only IP address format addresses only. Extra functionality is also provided via the ability to permit wildcard * entries when entering an IP address. Also an entered IP address can be pinged directly from the IPComboBox to provide an instant verification of an entered address. Addresses can set to include leading zeros and IPComboBox will automatically correct user enteries to the same format as they are entered. The IP address can be retrieved from the IPComboBox as one full string or as individual parts of the IP address. IPComboBox can be configured to permit disparate list types as a normal combobox. Lists can include aliases which remove the need for the user to know the IP address itself.
