求助开发可实现英文与莫尔斯码互转的VB Excel宏

核心实现逻辑 #

• 内置完整的标准莫尔斯码映射字典，覆盖26个英文字母、10个阿拉伯数字、常见标点符号，支持双向查找
• 内置方向选择交互，无需单独编写两个独立转换宏
• 自动处理输入内容的大小写兼容、无效字符识别、间隔规则匹配
• 转换完成后通过MsgBox直接返回结果，匹配失败的字符会单独标注提示

完整可运行代码 #

    Dim morseDict As Object
    Set morseDict = CreateObject("Scripting.Dictionary")
    morseDict.CompareMode = vbTextCompare ' 不区分大小写匹配
