To check spelling and display results in a message box

  1. 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);
