将VBA宏用户表单设计存储器从模板复制到目标工作簿,用JavaScript通过C++

可能的使用场景

Aspose.Cells允许你将VBA项目从一个Excel文件复制到另一个Excel文件。VBA项目由各类模块组成,例如文档、过程、设计器等。所有模块都可以用简单代码复制,但设计器模块还包含额外的数据,称为设计器存储,需要访问或复制。以下两个方法处理设计器存储。

将VBA宏用户表单DesignerStorage从模板复制到目标工作簿

请参阅以下示例代码。它将模板Excel文件中的VBA项目复制到空白工作簿中,并保存为输出Excel文件。打开模板Excel文件内的VBA项目即可看到一个用户表单,其包含Designer Storage,将通过VbaModuleCollection.designerStorage(string)**VbaModuleCollection.addDesignerStorage(string, number[])**方法复制。
