在VBA中扫描Excel列以查找特定单词

目前，我正在处理数据库Excel电子表格，我正在使用VBA实现系统的一些自动功能。我是VBA新手，所以我需要你的帮助：）

我的问题是：我有一个状态栏，用户需要从下拉列表中选择“完成”或“进行中”。我需要一个程序，可以扫描一个特定的列（例如S3）的单词“完成”。一旦检测到该单词，系统将自动向特定用户发送电子邮件，告诉他任务已完成

有人能帮我吗

谢谢！：）

更新：我编写了以下代码来搜索单词complete并向用户发送电子邮件（这是一个粗略的想法）

Sub-Send_Email_使用_VBA（）
Dim Email_主题、Email_Send_From、Email_Send_To、_
电子邮件抄送、电子邮件密件抄送、电子邮件正文为字符串
Dim Mail_对象，Mail_单个作为变量
电子邮件\u Subject=“测试结果”
电子邮件\u发送\u发件人=”fromperson@example.com"
电子邮件发送至“toperson@example.com"
'Email_Cc='someone@example.com"
'电子邮件_Bcc='someoneelse@example.com"
Email\u Body=“恭喜！！！！您已成功使用VBA发送电子邮件！！！！”
关于错误转到调试
设置Mail\u Object=CreateObject（“Outlook.Application”）
设置Mail\u Single=Mail\u Object.CreateItem（0）
单程邮寄
.Subject=电子邮件主题
.To=发送电子邮件至
.cc=电子邮件\u cc
.BCC=电子邮件\u BCC
.Body=电子邮件\正文
.发送
以
调试：
如果错误描述为“”，则MsgBox错误描述为“”
端接头

试试这个（试过并测试过）

你的问题很广泛-你能更具体地解释一下你的困境吗？我困在VBA程序中。我不知道从何处开始我需要扫描excel电子表格中的一列，以查找“完成”一词，一旦找到该词，将发送电子邮件。该列是否只需要包含“完成”一次，即可发送电子邮件，或者宏是否应该检查每一行，并在每一行第一次出现complete一词时发送电子邮件？是的，每次找到complete一词时都需要发送电子邮件。非常感谢代码！非常优雅的解决方案。我已经对代码进行了一次试运行，在第一次运行代码后，这行代码中出现了一个错误91：如果不是aCell，那么如果aCell.Address=bCell.Address，那么退出DoDid。您是否更改了代码中的任何内容？我可以看一个示例文件以便测试上述代码吗？如果是，那么你可以在www.wikisend.com上传文件并在这里共享链接。不，我没有更改上述代码。我上传了这个链接上的文件：非常感谢！最后一个问题…有没有办法实时运行宏？示例：如果excel文件已经打开，并且用户更改了状态，宏是否可以在更改完成后立即发送电子邮件？再次感谢：）是的。有关如何使用
