Examples

The following code example adds a RichTextBox control to the first paragraph in the document, assigns text to the control, and then formats the text. To use this example, run it from the ThisDocument class in a document-level project.

Private Sub WordRangeAddRichTextBox()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim RichTextBox1 As Microsoft.Office.Tools.Word.Controls. _
        RichTextBox = Me.Controls.AddRichTextBox( _
        Me.Paragraphs(1).Range, 75, 15, "RichTextBox1")
    RichTextBox1.Text = "Sample text"
    RichTextBox1.Select(0, 6)
    RichTextBox1.SelectionFont = New Font("Times New Roman", _
        10, FontStyle.Bold)
End Sub

private void WordRangeAddRichTextBox()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    Microsoft.Office.Tools.Word.Controls.RichTextBox
         richTextBox1 = this.Controls.AddRichTextBox(
         this.Paragraphs[1].Range, 75, 15, "richTextBox1");
    richTextBox1.Text = "Sample text";
    richTextBox1.Select(0, 6);
    richTextBox1.SelectionFont = new Font("Times New Roman",
        10, FontStyle.Bold);
