编写将宏写入另一个Excel文件的宏

Question

我有一些VBA代码,我需要复制到很多工作表(它是事件处理,所以它位于工作表而不是模块).

问题:是否可以编写一个允许我选择我需要修改的工作簿的宏,然后自动将代码写入所有选定工作簿的每个工作表？

没有直接的方法将模块从一个项目复制到另一个项目.要完成此任务,必须从Source VBProject导出模块,然后将该文件导入Destination VBProject.下面的代码将执行此操作.

函数声明是:

Function CopyModule(ModuleName As String, _
                    FromVBProject As VBIDE.VBProject, _
                    ToVBProject As VBIDE.VBProject, _
                    OverwriteExisting As Boolean) As Boolean

ModuleName 是要从一个项目复制到另一个项目的模块的名称.

FromVBProject是VBProject包含要复制的模块的.这是来源VBProject.

ToVBProject是VBProject要复制模块的内容.这是目的地VBProject.

OverwriteExisting表示如果ModuleName已存在,该怎么做ToVBProject.如果这是True现有的VBComponent将被删除ToVBProject.如果是False,并且VBComponent已经存在,则该函数不执行任何操作并返回False.

True如果成功或False发生错误,函数将返回.False如果满足以下任何条件,该函数将返回:

FromVBProject is nothing.
ToVBProject is nothing.
ModuleName is blank.
FromVBProject is locked.
ToVBProject is locked.
ModuleName does not exist in FromVBProject.
ModuleName exists in ToVBProject and OverwriteExisting is False.

完整代码如下所示:

Function CopyModule(ModuleName As String, _
    FromVBProject As VBIDE.VBProject, _
    ToVBProject As VBIDE.VBProject, _
    OverwriteExisting As Boolean) As Boolean

    ' CopyModule
    ' This function copies a module from one VBProject to
    ' another. It returns True if successful or  False
    ' if an error occurs.

    ' Parameters:
    ' --------------------------------
    ' FromVBProject         The VBProject that contains the module
    '                       to be copied.
    '
    ' ToVBProject           The VBProject into which the module is
    '                       to be copied.
    '
    ' ModuleName            The name of the module to copy.
    '
    ' OverwriteExisting     If True, the VBComponent named ModuleName
    '                       in ToVBProject will be removed before
    '                       importing the module. If False and
    '                       a VBComponent named ModuleName exists
    '                       in ToVBProject, the code will return
    '                       False.
