Question

i done to create a custom tab and ribbon button in outlook addin using Ribbon(XML) in C#.

i want to change the ribbon button image when i click the button.how to i acheive that?

here my XML Design:

<?xml version="1.0" encoding="UTF-8"?>

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load" loadImage="GetCustomImage">

  <ribbon>

    <tabs>

      <tab id="TabAddIns" label="Mail Security">


        <group id="Group2" >

          <button id="Encrypt" onAction="Encrypt_Click" label="Encrypt" size="large" image="email-security.png" getVisible="Control_Visible" />


        </group>

      </tab>

    </tabs>

  </ribbon>

</customUI>

GetCustomImage Function:

public stdole.IPictureDisp GetCustomImage(string imageName)
        {

                return PictureConverter.ImageToPictureDisp(Properties.Resources.email_security);


        }
