> I have built the following DLL...

You are trying to use a global hook.  Your DLL is going to be injected into 
every running process, and thus each process is going to be running its own 
copy of the DLL's variables.  Each process is going to have its own copy of 
your HHOOK and HWND variables, but only the process that originally installs 
the hook will have accurate values for them.  So you need to store your 
variables into a block of shared memory so that every process has equal 
access to those values.  Otherwise your hook will not work correctly.  Use 
CreateFileMapping() and MapViewOfFile() to set asside the block of shared 
memory.

Please go to http://www.deja.com and search through the newsgroup archives. 
I have posted sample code on this topic many times before.

> Why is this not working?

Because you did not set up the DLL so that all of the other processes can 
access the HHOOK and HWND values that the DLL uses.

Because only your application has access to the correct HHOOK and HWND 
variable values.

Then you must store the HHOOK and HWND values into shared memory.
