使用VBA宏

Visual BasicFor Applications(VBA)forMicrosoft Word是一种简单但功能强大的编程语言，可用于扩展功能。 Aspose.WordsAPI提供了三个类来访问VBA项目源代码:

• VBAProject类提供对VBA项目信息的访问
• VBAModulesCollection类返回VBA项目模块的集合
• VbaModule类提供对VBA项目模块的访问

创建VBA项目

Aspose.WordsAPI提供Document.VbaProject属性以获取或设置文档中的VbaProject。

下面的代码示例演示如何创建VBA项目和VBA模块以及基本属性，例如Name和Type:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>();

// Create a new VBA project.
System::SharedPtr<VbaProject> project = System::MakeObject<VbaProject>();
project->set_Name(u"AsposeProject");
doc->set_VbaProject(project);

// Create a new module and specify a macro source code.
System::SharedPtr<VbaModule> vbModule = System::MakeObject<VbaModule>();
vbModule->set_Name(u"AsposeModule");
vbModule->set_Type(VbaModuleType::ProceduralModule);
vbModule->set_SourceCode(u"New source code");

// Add module to the VBA project.
doc->get_VbaProject()->get_Modules()->Add(vbModule);

doc->Save(outputDataDir +  u"WorkingWithVbaMacros.CreateVbaMacros.docm");

读取宏

Aspose.Words还为用户提供了读取VBA宏的能力。

下面的代码示例演示如何从文档中读取VBA宏:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"VbaProject.docm");

if (doc->get_VbaProject() != nullptr)
{
    for (System::SharedPtr<VbaModule> module : System::IterateOver(doc->get_VbaProject()->get_Modules()))
    {
        std::cout << module->get_SourceCode().ToUtf8String() << std::endl;
    }
}

编写或修改宏

使用Aspose.Words，用户可以修改VBA宏。

下面的代码示例演示如何使用SourceCode属性修改VBA宏:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"VbaProject.docm");
System::SharedPtr<VbaProject> project = doc->get_VbaProject();

System::String newSourceCode = u"Test change source code";

// Choose a module, and set a new source code.
project->get_Modules()->idx_get(0)->set_SourceCode(newSourceCode);

克隆VBA项目

使用Aspose.Words也可以克隆VBA项目。

下面的代码示例演示如何使用创建现有项目副本的Clone属性克隆VBA项目:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"VbaProject.docm");
System::SharedPtr<VbaProject> project = doc->get_VbaProject();

System::SharedPtr<Document> destDoc = System::MakeObject<Document>();

// Clone the whole project.
destDoc->set_VbaProject(doc->get_VbaProject()->Clone());

destDoc->Save(outputDataDir + u"WorkingWithVbaMacros.CloneVbaProject.docm");

克隆VBA模块

如果需要，您还可以克隆VBA模块。

下面的代码示例演示如何使用创建现有项目副本的Clone属性克隆VBA模块:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>(inputDataDir + u"VbaProject.docm");
System::SharedPtr<VbaProject> project = doc->get_VbaProject();

System::SharedPtr<Document> destDoc = System::MakeObject<Document>();

destDoc->set_VbaProject(System::MakeObject<VbaProject>());

// Clone a single module.
System::SharedPtr<VbaModule> copyModule = doc->get_VbaProject()->get_Modules()->idx_get(u"AsposeModule")->Clone();
destDoc->get_VbaProject()->get_Modules()->Add(copyModule);

destDoc->Save(outputDataDir + u"WorkingWithVbaMacros.CloneVbaModule.docm");
