Thanks, I am working on it. What I would like to know is how do you know what value SPI_GETWORKAREA is?
Don't I need to set it before hand, something like SPI_GETWORKAREA = 12, otherwise I am just sending an empty variable?
And if I do need to set it, how to I know what int value SPI_GETWORKAREA should be?
