* NOTES
|
|
*
|
|
* TODO:
|
|
* -Edit control doesn't support the ES_CENTER style which prevents
|
|
* this ipaddress control from having centered text look like the
|
|
* windows ipaddress control
|
|
* -Check all notifications/behavior.
|
|
* -Optimization:
|
|
* -include lpipsi in IPADDRESS_INFO.
|
|
* -CurrentFocus: field that has focus at moment of processing.
|
|
* -connect Rect32 rcClient.
|
|
* -check ipaddress.cpp for missing features.
|
|
* -refresh: draw '.' instead of setpixel.
