Question

我有一个excel文件，其中包含从另一台计算机上存储的文件中检索数据的单元格。我需要更新所有这些公式中的文件路径，但是每次更新公式时都会出现非常繁琐的问题，会出现一个打开的文件窗口。我要更改此位置的位置也不在我的计算机上。

有没有快速的方法来更新文件路径公式而不打开此对话框窗口？

我需要改变我的路径

Answer 1

在＆＃34;数据＆＃34;选项卡，单击＆＃34;编辑链接＆＃34; - 这应该显示你链接到的文件，你可以＆＃34;改变来源＆＃34;更新它。或者，您可以执行简单的查找/替换（CTRL + F，然后单击＆＃34;替换＆＃34;并键入需要替换的路径，然后在替换区域中，放置新路径）。

Answer 2

您可以使用VBA更改公式。

但首先，我建议您在只有一个单元格中使用它，并且在公式中，您添加此单元格，而不是真正的路径。这样，下次需要更改时，只更改一个单元格。

现在编码，改变A2和B5的例子：

Sub Change()
    Range("A2").Formula = type the formula here between quotes
    Range("B5").Formula = type the formula here between quotes
end sub

如果列中有大量单元格，则可以循环：

For i = 1 to 20 'say you have cells from row 1 to 20
    Cells(i,3).Formula = type the formula here between quotes
    'the number 3 above is the third column: C
next

Answer 3

这很晚了，但是一个可以避免在单击“全部替换”时出现恼人对话框的选项是在路径的开头插入一些随机字符，这将阻止Excel认为字符串是实际的链接。然后，您应该能够编辑该路径中需要更改的部分，完成后，再执行一次全部替换，基本上删除插入的随机字符。

您当然需要小心，因为如果您选择的随机字符恰好位于其他公式中，则“全部替换”可能会产生一些意外结果

你可以写在你的代码上：

import 'package:flutter/material.dart';
import 'MP_helper.dart';
import 'MP_Student.dart';

class AddStudentPage extends StatefulWidget {
  const AddStudentPage({Key key}):super(key: key);

  @override
  _AddStudentPageState createState() => _AddStudentPageState();
}

class _AddStudentPageState extends State<AddStudentPage> {
  final GlobalKey<FormState> _formStateKey = GlobalKey<FormState>();
  Future<List<NewStudent>> mpStudents;
  int mpStudentIdForUpdate;
  String _mpStudentName;
  String _mpStudentDepartment;
  String _mpStudentDate;
  bool isUpdate = false;
  var _value1 = false;
  var _value2 = false;
  var _value3 = false;
  MPHelper mpHelper;
  DateTime mpPickedDate;
  DateTime mpSelectedDate = DateTime.now();
  final _mpStudentNameController = TextEditingController();
  final _mpStudentDepartmentController = TextEditingController();

  @override
  void initState(){
    super.initState();
    mpHelper = MPHelper();
    mpPickedDate = DateTime.now();
    _mpStudentDate = mpPickedDate.toString().substring(0,10);
    refreshMPStudentList();
  }
  refreshMPStudentList(){
    setState((){
      mpStudents = mpHelper.getNewStudents();
    });
  }
