Thanks! :)

You can also use  Registry Configuration Service provider for this:

For Left Soft Key:
SK1Label value would be the string that you want to display
SK1App.exe value would be the exe name

<wap-provisioningdoc>
  <characteristic type="Registry">
     <characteristic type="HKCU\Software\Microsoft\Today\Keys\112">
        <parm name="" value="SK1Label" datatype="string" />
        <parm name="Open" value="SK1App.exe" datatype="string" />        
     </characteristic>
  </characteristic>
</wap-provisioningdoc>

For Right Soft key
<wap-provisioningdoc>
  <characteristic type="Registry">
     <characteristic type="HKCU\Software\Microsoft\Today\Keys\113">
        <parm name="" value="SK2Label" datatype="string" />
        <parm name="Open" value="SK2App.exe" datatype="string" />        
     </characteristic>
  </characteristic>
</wap-provisioningdoc>

I am not sure if there is api for it...but you can acheive this with registry.
You would need to modify following registry key for this:
check out these keys:
[HKEY_CURRENT_USER\Software\Microsoft\Today\Keys\112] for Left Soft Key
and
[HKEY_CURRENT_USER\Software\Microsoft\Today\Keys\113] for Right Soft key

Hope it helps..:-)

Hi,

In the today screen, the left and right soft keys are by default assigned to
"Calendar" and "Contacts".
How could I change these menu items and their functions (programmatically)?
