使用DDE在Windows 7中运行遗留程序的问题

Question

我的行政人员遇到了一个大问题，我正在把他们的困境转述给：

我们有一个旧的数据库应用程序(写在Advancement4GL/OpenEdge中)，它调用WordPerfect X3来生成报表。WordPerfect可执行文件的路径是在数据库应用程序中硬编码的，以及要插入到数据库中的扫描PDF的位置，我们无法修改程序。

我们的大多数工作站已经成功地从WinXP迁移到Win7，遗留应用程序在尝试调用WordPerfect之前运行良好，表示它找不到可执行文件(即使X3安装在WinXP上使用的完全相同的路径上).扫描的文档文件夹也是如此。

有什么建议吗？

更新：

今天早上我一直在帮我的管理人员提出各种建议.我们检查了文件权限，查看了带有十六进制编辑器的编译(.r)文件(谢谢@Tom和@Ernest)，并使用Notepad++搜索了所有源代码(.p)中的文件。

这里是我发现的：程序并不是直接调用WordPerfect (正如我最初被告知的那样)，而是使用DDE。以下是Advancement4GL生成的错误消息：

​

我意识到DDE和Win7存在问题，所以我想知道是否存在需要修改的注册表项，或者对其有什么影响。

我将从下面的源代码中摘录一段内容，希望有人能认识到正在发生的事情(我不太熟悉Advancement4GL，所以对我来说这都是希腊语)：

Answer 1

我同意这听起来很像权限问题。

尽管如此..。你确定你没有办法修改它吗？这不是通常由供应商提供的那种功能--听起来更像是定制的修改。

您有.p或.w文件吗？(这些是Advancement4GL源代码。)还是只有.r文件？(这是编译后的代码。)

运行"showcfg“(开始菜单上的"config”图标) --如果您有开发许可证，可能更多的是不知道如何更改它，而不是没有更改它的能力。

实际上，您“无法修改”的程序文件可以使用十六进制编辑器进行编辑；在过去，已经多次这样做了。路径几乎可以肯定地位于二进制文件内，具有可读的文本格式。

否则，您可以在VM映像(即VMware player)中运行XP并在其上安装程序；它们可能会更快乐。
