You can use the WM_COPYDATA message. The reason you method does not work is
because you are passing a pointer to a memory location of one process to
another. This memory location is not valid / different for the second
process and you will either get garbage when you try to read from the
pointer, or most likely, you will get an EAccessViolation. With
WM_COPYDATA, Windows translates the pointer for you so that it is valid for
the second process to *READ* the memory. Don't try to write to it.
Hope this helps.
Dennis.
