* TODO:
|
|
* -Check ranges when changing field-focus.
|
|
* -Check all notifications/behavior.
|
|
* -Optimization: include lpipsi in IPADDRESS_INFO.
|
|
* -CurrentFocus: field that has focus at moment of processing.
|
|
* -connect Rect32 rcClient.
|
|
* -handle right and left arrows correctly. Boring.
|
|
* -split GotoNextField in CheckField and GotoNextField.
|
|
* -check ipaddress.cpp for missing features.
|
|
* -refresh: draw '.' instead of setpixel.
|
|
* -handle VK_ESCAPE.
