【问题描述】：
我想查看当 MSI 以二进制模式运行时显示在 UI 上的字符串/文本。
基本上我有本地化的 wxl 文件和本地化的 msi。想比较一下文字。
所以我的方法是查看要比较的字符串的二进制内容。谁能建议我可以使用哪些工具？
使用 orca 我可以看到字符串。但我想看看那些的二进制/十六进制值。
非常感谢
最好的问候， 马克

【问题描述】：
我不知道将字符串导出为二进制的工具。在大多数情况下，它实际上是不需要的。
如果您确实需要获取有关字符串的二进制信息，您可以使用IStorage::OpenStream、IStream::Stat 和STATFLAG_NONAME 参数和IStream::Read 直接从MSI 读取信息。有关 sting 的信息保存在名为“_StringData”和“_StringPool”的流中。流的名称以简单的方式编码。如果您有兴趣，我可以向您发布显示如何解码名称的代码。
更新：我从旧实用程序中准备了一个小演示。该演示从“_StringData”和“_StringPool”加载字符串，并以可读格式转储信息。如果调整行中的常量
bSuccess = LoadStringPool (pStg, TRUE, 80, 10, 10);
（见下文）您可以转储更完整的信息。以同样的方式，您可以轻松修改代码以将相应的流保存为二进制文件。
