Simulate a mouse button click - SendInput or something else

Hi Folks,
 
What am I trying to do
 
I need to simulate a mouse click in my application (deploying to Handheld MC9200, developed in C# Visual Studio 2008, WCF and .Net 3.5). Previously in the application, which was running on a Psion 7535, I was using
 
 
DllImport("coredll.dll", EntryPoint = "SendInput", SetLastError = true)]
 
static extern uint SendInput(
 
uint nInputs,
 
INPUT[] pInputs,
 
int cbSize);
 
and using SendInput to get my result which was working fine.
 
On migration to the MC9200 this call does nothing.
 
Basically think x 20 y 15 I want to do a left mouse button click
 
 
What I have tried to do
 
On the new handheld (MC9200) the above code simply returns a 0 (i.e. it does nothing).
 
Searching this forum returns nothing relevant
 
Google suggests a few things
 
Tried : https://stackoverflow.com/questions/8962850/sendinput-fails-on-64bit : Failed : Can't find PInvoke DLL 'user32.dll'.
 
Other google hits all refer to 'user32.dll' so I was wondering...
 
Am I missing something obvious here?
 
Should I still be using sendInput or indeed coredll? Shirley  ; )  this has been done before?
 
Thanks in advance for any and all help

Update

The existing call to SendInput works fine, I was simply passing in incorrect x and y co-ordinates (doh!) as Screen positions have changed since the move to the new handheld

Apologies to anyone who's invested any time into looking at this issue
