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 VSTO Add-in projects for Word. For more information, see Features available by Office application and project type.

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);
