Excel VBA - 如何在代码编辑器中打开行号

请帮忙:如何在Excel VBA代码编辑器中打开行号？我正在使用Excel 2013版本.

谢谢.

Answer 1

这是我在VBE IDE中添加行号的代码.它提供的解决方案的改进,在这里用Excel MVP mikerickson.我已经解决了这个问题,因为在我遇到过的极少数情况下,VBE无法进入调试模式,例如在代码中有.ReplaceLine方法时.实际上,一旦执行它就无法进入调试模式,因此Erl可能对调试很有用(而不是Debug.Print).我添加了几个功能,例如:

可以将行号添加为标签:10: Dim foo as bar或者通过选项卡从代码中分离单个数字:10 Dim foo as bar

是否可以将行号添加到过程语句的结尾,并将过程声明行的缩进与numberered的End语句行匹配.或不.

是否可以在空行中添加行号

[WIP]可以将行号添加到模块中的特定过程

[WIP]匹配代码行的所有缩进与行号以匹配最后一行缩进的缩进.如果是最后一行200: End Sub,则该行将30: With ActiveSheet重新缩进为30: ActiveSheet

[WIP]添加一个VBE IDE命令,直接使用当前模块/ proc作为参数进行调用

你可以这样打电话:

Sub AddLineNumbers_vbLabelColon()
    AddLineNumbers wbName:="EvaluateCall.xlsm", vbCompName:="ModLineNumbers_testDest", LabelType:=vbLabelColon, AddLineNumbersToEmptyLines:=True, AddLineNumbersToEndOfProc:=True, Scope:=vbScopeAllProc
End Sub

Sub AddLineNumbers_vbLabelTab()
    AddLineNumbers wbName:="EvaluateCall.xlsm", vbCompName:="ModLineNumbers_testDest", LabelType:=vbLabelTab, AddLineNumbersToEmptyLines:=True, AddLineNumbersToEndOfProc:=True, Scope:=vbScopeAllProc

作为提醒,这里有一些关于行号的编译规则:

在Sub/Function声明语句之前不允许
不允许在proc之外
不允许在行继续符"_"后面的行(下划线)
每个代码行不允许有多个标签/行号~~>必须测试除行号以外的现有标签,否则会发生编译错误,试图强制执行行号.
不允许使用已经具有特殊VBA含义的字符~~>允许的字符是[aZ],[0-9],é,è,ô,ù,€,£,§甚至":"单独!
编译器会在标签前修剪任何空格~~>因此,如果有标签,则该行的第一个字符是标签的第一个字符,它不能是空格.
使用冒号附加行号将导致在":"和第一个下一个字符之间插入一个空格(如果没有)
当附加一个带有制表符/空格的行号时,最后一个数字和第一个下一个字符之间必须至少有一个空格,编译器不会像对带有冒号分隔符的标签那样添加它
.ReplaceLine方法将覆盖编译规则而不显示任何编译错误,就像在选择新行或手动重新启动编译时在设计模式中一样
编译器"比VBA环境/系统更快":例如,在带有冒号且没有任何空格的行号后面插入.ReplaceLine,如果调用.Lines属性来获取新字符串,则空格(在冒号字符和字符串的第一个字符之间)已经附加在该字符串中!
调用.ReplaceLine后(从编辑模块内部或外部)进入调试模式,直到代码运行,并执行复位.
