I am trying to insert a shape.textbox into a word doc. If it is already there I would like to clear out any text that is already in there and write new text in the textbox. If it is not already there, I would like to create it so I can put the text inside it.

I have been able to create the textbox and fill it with text, but if I access the document again, I end up with multiple instances of the textbox as it is recreated each time.

Hi Derek,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

You can create or edit an existing textbox in document by using the code similar to below.

Document doc = new Document(dataDir + "Test Document.doc");

bool hasTextBox = false;

Shape textBox = null;

// Try to find existing textbox

NodeCollection nodes = doc.GetChildNodes(NodeType.Shape, true);

foreach (Shape node in nodes)


if (node.ShapeType == ShapeType.TextBox)


hasTextBox = true;

textBox = node;



// Create a new textbox if no textbox already exists

if (!hasTextBox)


textBox = new Shape(doc, ShapeType.TextBox);

// Set Textbox size

textBox.Width = 100;

textBox.Height = 100;

// Insert one empty paragraph into the textbox.

Paragraph par = new Paragraph(doc);

par.AppendChild(new Run(doc));


// Insert textbox into the document.



// Change text in textbox

textBox.FirstParagraph.Runs[0].Text = "Text Inserted";

doc.Save(dataDir + "Test Document Out.doc");

If you need any futher help please ask.


I can see how that would work. But what if I wanted to remove any duplicate text boxes, then create a new one to write my write my text to.

My concern is that I will end up with too many text boxes on the page.

PS: I''m using VB.net to write the program.

Thank you for additional information. Maybe, in your case, you can use Shape.Name to identify textboxes. In this case, you will be able to avoid duplications:


Best regards.

Hi Derek,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Here is the code above in Visual Basic format for your reference if needed.

Dim doc As New Document(dataDir & "Test Document.doc")

Dim hasTextBox As Boolean = False

Dim textBox As Shape = Nothing

' Try to find existing textbox

Dim nodes As NodeCollection = doc.GetChildNodes(NodeType.Shape, True)

For Each node As Shape In nodes

If node.ShapeType = ShapeType.TextBox Then

hasTextBox = True

textBox = node

End If

Next node

' Create a new textbox if no textbox already exists

If (Not hasTextBox) Then

textBox = New Shape(doc, ShapeType.TextBox)

' Set Textbox size

textBox.Width = 100

textBox.Height = 100

' Insert one empty paragraph into the textbox.

Dim par As New Paragraph(doc)

par.AppendChild(New Run(doc))


' Insert textbox into the document.


End If

' Change text in textbox

textBox.FirstParagraph.Runs(0).Text = "Text Inserted"

doc.Save(dataDir & "Test Document Out.doc")
