Dim richTextControl2 As Microsoft.Office.Tools.Word.RichTextContentControl

Private Sub AddRichTextControlAtRange()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    richTextControl2 = Me.Controls.AddRichTextContentControl(Me.Paragraphs(1).Range, _
        "richTextControl2")
    richTextControl2.PlaceholderText = "Enter your first name" 
End Sub

private Microsoft.Office.Tools.Word.RichTextContentControl richTextControl2;

private void AddRichTextControlAtRange()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();

    richTextControl2 = this.Controls.AddRichTextContentControl(this.Paragraphs[1].Range,
        "richTextControl2");
    richTextControl2.PlaceholderText = "Enter your first name";

Private Sub AddRichTextControlAtRange()
    If Me.Application.ActiveDocument Is Nothing Then 
        Return 
    End If 

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    richTextControl2 = vstoDoc.Controls.AddRichTextContentControl( _
        vstoDoc.Paragraphs(1).Range, _
        "richTextControl2")
    richTextControl2.PlaceholderText = "Enter your first name" 
End Sub

private Microsoft.Office.Tools.Word.RichTextContentControl richTextControl2;

private void AddRichTextControlAtRange()
{
    if (this.Application.ActiveDocument == null)
        return;

    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();

    richTextControl2 = vstoDoc.Controls.AddRichTextContentControl(vstoDoc.Paragraphs[1].Range,
        "richTextControl2");
