Var
    LicManager: ILicenseManager;
    Feature: String;
    StatusCode: UiLicenseStatusCode;
Begin
    LicManager := WinApplication.Instance.LicenseManager;
    Feature := Editbox1.Text;
    StatusCode := LicManager.DeleteFeature(Feature);
    If StatusCode = UiLicenseStatusCode.Success Then
        WinApplication.InformationBox("Code is successfully deleted");
    Else
        WinApplication.InformationBox("Error: " + StatusCode.ToString);
    End If;
End Sub Button1OnClick;

Clicking the button deletes the code for the feature specified in Editbox for the current session. The appropriate message is displayed with code deleting result. If errors occur on deleting, the message with the code of the occurred error is displayed.
