To check the spelling in a document, use the CheckSpelling method. This method returns a Boolean value that indicates whether the supplied parameter is spelled correctly.

Applies to: The information in this topic applies to document-level projects and application-level projects for Word 2013 and Word 2010. For more information, see Features Available by Office Application and Project Type.

To check spelling and display results in a message box

• Call the CheckSpelling method and pass it a range of text to check for spelling errors. To use this code example, run it from the ThisDocument or ThisAddIn class in your project.

  Dim result As String = "Spelled incorrectly." 
  
  If Me.Application.CheckSpelling(Me.Range.Text) = True Then
      result = "Spelled correctly." 
  End If
  
  MessageBox.Show(result)
  

  string result = "Spelled incorrectly.";
  
  object startLocation = this.Content.Start;
  object endLocation = this.Content.End;
  bool spellCheck = this.Application.CheckSpelling(
      this.Range(ref startLocation, ref endLocation).Text);
  
  if (spellCheck == true)
  {
      result = "Spelled correctly.";
  }
  
  MessageBox.Show(result);
