This article demonstrates how to add, access, and remove VBA macros using **Aspose.Slides for C++**.

## **Add a VBA Macro**

Create a presentation with a VBA project and a simple macro module.

```cpp
static void AddVbaMacro()
{
    auto presentation = MakeObject<Presentation>();

    presentation->set_VbaProject(MakeObject<VbaProject>());

    auto module = presentation->get_VbaProject()->get_Modules()->AddEmptyModule(u"Module");
    module->set_SourceCode(u"Sub Test()\n MsgBox \"Hi\" \nEnd Sub");

    presentation->Dispose();
}
```

## **Access a VBA Macro**

Retrieve the first module from the VBA project.

```cpp
static void AccessVbaMacro()
{
    auto presentation = MakeObject<Presentation>();

    presentation->set_VbaProject(MakeObject<VbaProject>());

    auto module = presentation->get_VbaProject()->get_Modules()->AddEmptyModule(u"Module");
    module->set_SourceCode(u"Sub Test()\n MsgBox \"Hi\" \nEnd Sub");

    auto firstModule = presentation->get_VbaProject()->get_Module(0);

    presentation->Dispose();
}
```

## **Remove a VBA Macro**

Delete a module from the VBA project.

```cpp
static void RemoveVbaMacro()
{
    auto presentation = MakeObject<Presentation>();

    presentation->set_VbaProject(MakeObject<VbaProject>());

    auto module = presentation->get_VbaProject()->get_Modules()->AddEmptyModule(u"Module");
    module->set_SourceCode(u"Sub Test()\n MsgBox \"Hi\" \nEnd Sub");

    presentation->get_VbaProject()->get_Modules()->Remove(module);

    presentation->Dispose();
}
```
