Excel VBA代码模块的源代码控制

Question

我希望能够控制我的Excel电子表格的VBA模块(目前使用的是Excel 2003 SP3),以便我可以共享和管理一堆不同电子表格使用的代码 - 因此我想重新加载它们从电子表格打开时的文件.

我有一个名为Loader.bas的模块,我用它来完成大部分驴工作(加载和卸载所需的任何其他模块) - 我希望能够尽快从文件中加载它当电子表格打开时.

我已将以下代码附加到Workbook_Open事件(在ThisWorkbook类中).

Private Sub Workbook_Open()
    Call RemoveLoader
    Call LoadLoader
End Sub

RemoveLoader(也在ThisWorkbook类中)包含以下代码:

Private Sub RemoveLoader()
    Dim y As Integer
    Dim OldModules, NumModules As Integer
    Dim CompName As String

    With ThisWorkbook.VBProject
        NumModules = ThisWorkbook.VBProject.VBComponents.Count
        y = 1
        While y <= NumModules
            If .VBComponents.Item(y).Type = 1 Then
                CompName = .VBComponents.Item(y).Name
                If VBA.Strings.InStr(CompName, "Loader") > 0 Then
                    OldModules = ThisWorkbook.VBProject.VBComponents.Count
                    .VBComponents.Remove .VBComponents(CompName)
                    NumModules = ThisWorkbook.VBProject.VBComponents.Count
                    If OldModules - NumModules = 1 Then
                        y = 1
                    Else
                        MsgBox ("Failed to remove " & CompName & " module from VBA project")
                    End If
                End If
            End If
            y = y + 1
        Wend
    End With
End Sub

这可能有点过于复杂和略显粗糙 - 但我正在尝试我能找到的所有东西来加载外部模块!

通常,当我打开电子表格时,RemoveLoader函数发现VBA项目中已经包含一个"Loader1"模块,它无法删除,并且它也无法从文件中加载新的Loader模块.

任何想法,如果我想做什么是可能的？Excel似乎非常喜欢在这些模块名称上添加1 - 无论是在加载还是删除时(我不确定哪个).

这里有一个很好的解决vba版本控制问题的方法:https://github.com/hilkoc/vbaDeveloper

关于这一点的好处是它会在您保存工作簿时自动导出代码.此外,当您打开工作簿时,它会导入代码.

您不需要运行任何构建脚本或maven命令,也不需要对工作簿进行任何更改.它适用于所有人.

它还解决了导入问题,其中ModName等模块作为ModName1导入到重复模块中.导入工作正常,即使多次执行也是如此.

作为奖励,它带有一个简单的代码格式化程序,允许您在VBA编辑器中编写时格式化vba代码.

查看VBAMaven页面。我有一个使用相同概念的本地解决方案。我有一个带有一堆源代码，一个蚂蚁构建和一个“导入” VB脚本的公共库。Ant控制着构建，该构建接受一个空白的excel文件并将所需的代码推送到其中。@Mike绝对正确-任何重复的模块定义都会在模块名称后自动添加一个数字。同样，类模块（如在Sheet和ThisWorkbook中）需要特殊处理。您无法创建这些模块，必须读取输入文件并将缓冲区写入适当的模块。这是我当前用来执行此操作的VB脚本。包含@分隔文本的部分（即@build file @）是占位符-ant build将这些标签替换为有意义的内容。它不是完美的，但是对我有用。
