VBA Macros in Word documents

Visual Basic for Applications is human-readable and editable programming code that gets generated when you record a macro. Today, it is widely-used with other Microsoft Office applications such as MS-Word, MS-Word, and MS-Access.

The VBA Project is where the modules and forms are stored when you write VBA code in Word.

In GemBox.Document vba project is represented by VbaProject element and can be loaded from and saved to macro-enabled (DOCM) file format only.

The following example shows how you can create an Word VBA module in C# and VB.NET.

    {
        // If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        var document = new DocumentModel();

        var section = new Section(document);
        document.Sections.Add(section);

        // Create the module.
        VbaModule vbaModule = document.VbaProject.Modules.Add("SampleModule", VbaModuleType.Document);
        vbaModule.Code = 
@"Sub WriteHello()
    Selection.TypeText Text:=""Hello World!""
End Sub";

        // Save the document as macro-enabled Word file.
        document.Save("AddVbaModule.docm");
    }
}

Imports GemBox.Document
Imports GemBox.Document.Vba

Module Program

    Sub Main()

        ' If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY")

        Dim document As New DocumentModel()

        Dim section As New Section(document)
        document.Sections.Add(section)

        ' Create the module.
        Dim vbaModule As VbaModule = document.VbaProject.Modules.Add("SampleModule", VbaModuleType.Document)
        vbaModule.Code =
"Sub WriteHello()
    Selection.TypeText Text:=""Hello World!""
End Sub"

        ' Save the document as macro-enabled Word file.
        document.Save("AddVbaModule.docm")
