Delphi中是否可以将断点保存在项目的.DSK文件中,而不是其他桌面设置?
大多数.DSK妨碍了,但是无法保存调试断点是一种真正的痛苦(特别是当它们有条件或附加了操作时)。
答案 0 :(得分:6)
我从未遇到IDE设施只保存.Dsk文件中与断点相关的设置。
为了娱乐,我想我会尝试使用OTA通知通过IDE加载项实现某些功能。下面的代码运行良好安装到D7中安装的软件包中,IDE似乎很高兴重新打开一个项目,其.Dsk文件已由它处理(并且断点已设置!)。
正如您所看到的,当使用ofnProjectDesktopSave的NotifyCode调用时,它会捕获OTA通知程序的FileNotification事件,该事件发生在IDE保存.Dsk文件之后(最初使用扩展名'。$ $$',我在第一次写这篇文章时会注意到这一点)。然后它读取保存的文件文件,并准备一个更新的版本,除了指定的部分列表之外的所有部分都将被删除。然后,用户可以选择将稀疏文件保存回磁盘。我使用TMemIniFile进行大部分处理只是为了最大限度地减少所需的代码量。
我在阅读你的q时没有编写OTA通知程序的经验,但下面引用的GE专家常见问题解答非常有用,尤其是示例通知程序代码。
通常,删除项目的.Dsk文件是无害的,但请谨慎使用此代码,因为它没有经过压力测试。
更新:我注意到TIdeNotifier.FileNotification事件收到的文件名实际上有一个'。$$$'的扩展名。我不太清楚为什么会这样,但在将文件重命名为xxx.Dsk之前,似乎会调用该事件。我认为这需要改变方式 保存稀疏版本,但显然不是。
更新#2:使用文件夹监控实用程序查看实际发生的情况后,发现代码收到的桌面保存通知只是与之相关的许多操作中的第一个.Dsk文件。这些包括将任何现有版本的.Dsk文件重命名为.~Dsk文件,最后将。$$$文件保存为新的.Dsk文件。
