在评估 PowerBuilder 转换项目时要注意什么？
我一直在尝试为 PowerBuilder 9 到 11.5 制定规范 相对复杂的应用程序的迁移。授予PowerBuilder 并不是我的专长，我在试图证明一个问题的合理性时遇到了问题 项目这一部分的估计（以及 PowerBuilder 人员 我最近一直在与有一些个人问题的人交谈，并且已经不在了 沟通）。这些是我们已经看到并可以评估的一些指标：
-PBL 文件
-主窗口
-数据窗口
-函数
（不，我们没有该项目的可用源）
哪些指标特别有用，以及任何给定的“单元”（例如数据窗口）需要多长时间？
I've been trying to do a spec for a PowerBuilder 9 to 11.5
migration of a relatively complex application. Granted PowerBuilder
is not really my specialty I'm having issues trying to justify an
estimate for this part of the project (and the PowerBuilder people
I've been talking with have had some personal issues lately and are out of
communication). These are some of the metrics that we have seen and can evaluate:
-PBL Files
-Main Windows
-Data Windows
-Functions
(no we don't have the source available on this project)
What metrics in particular are helpful and how long would any given "unit" such as a Data Window take?

大多数 PowerBuilder 迁移都相当顺利。可能让您从 9.0 升级到 11.5 的最大因素是 (a) 富文本编辑控件（如果使用）的变化以及 (b) Unicode 与 ANSI。如果您有传递字符串的外部函数调用，并且只需要添加 ;ANSI 后缀或迁移到调用的 Unicode 版本，则后者将主要成为问题。
因此，查看是否使用了富文本编辑控件，并查看声明了多少外部函数调用。如果您两者都没有，那么只需在 11.5 中打开项目（当然在进行备份之后）并允许 11.5 进行迁移即可。
Most PowerBuilder migrations are rather smooth. The biggest thing that might get you moving from 9.0 to 11.5 are (a) the change in the Rich Text Edit control (if used) and (b) Unicode versus ANSI. The later will primarily be an issue if you have external function calls that pass strings, and only require the addition of a ;ANSI suffix or a migration to the Unicode version of the call.
So, look to see if the Rich Text Edit control is used, and look to see how many external function calls are declared. If you don't have any of either, it would be as simple as opening the project up in 11.5 (after making a backup of course) and allowing 11.5 to do the migration.
已经有一段时间了，具体的我不记得了，但是我们从9到11.5的升级非常顺利。
Its been a while, and I don't remember the specifics, but our upgrade from 9 to 11.5 went very smoothly.
