Hi all, the VC6LineNumberAddin is available now, you can try the trial version from http://davidhowecn.googlepages.com/V...umberAddin.dll.
Because this is a trial version, it has some limits: you can only have 3 code windows line-numbered at most; and the max line number displayed is limited to 3000.
To use it, select menu "Tools"->"Customize"->"Add-ins and Macro files" from VC++6.0 IDE.
Welcome bug reports.
BTW, this version does not support splitted code windows, and the language is Chinese only, so there maybe some strange chars on dialogs.
