>Note that the second parameter is the message to send, but it's an integer! In fact, all the parameters are integers. The example on http://www.amyuni.com/downloads/tn02.htm indicates that the changed Devmode is what you'd send in this second parameter, but it looks like the same problem I have with SetPrinter().

A bit more on this...

I've found that the WM_DEVMODECHANGE parameter in the example is actually a constant from the windows.h file. It's 28, so I just sent the function a 28 as the second parameter. It doesn't blow up, but it also doesn't seem to do anything. So I'm back to where I started, i.e. trying to figure out why the call to DocumentProperties that's supposed to save the Devmode settings isn't doing its job.
