在 flex NativeProcess 中传递参数答案

【问题标题】：pass parameter in flex NativeProcess在 flex NativeProcess 中传递参数
【发布时间】：2012-04-05 07:47:33
【问题描述】：

我想将两个参数传递给 nativeProcess。

当我使用带有参数的 windows 命令运行 exe 文件时，它正在运行。窗口命令是“abc.exe a.txt b.txt”

如何使用 flex nativeProcess 将两个参数传递给该格式的 exe？

这是我目前所拥有的：

【问题讨论】：

由于无法保证您将保持外部链接有效，因此最好将代码示例复制到您的问题中。它将帮助其他用户将来理解这个问题。
非常感谢您的指导和编辑。我会记得，但我找到了答案。我将工作目录分配给 nativeProcess，如上面 nativeProcessStartupInfo_Obj.workingDirectory = File.applicationStorageDirectory.resolvePath();它正在工作
然后将您对问题的解决方案作为答案发布并接受它。这也有利于日后参考。
