Hi

I've a little problem to understand what DrvConvertDevMode,
DrvDocumentPropertySheets and DrvDevicePropertySheets have to do.
So lets start with the question about DrvConvertDevMode. If you get the
parameter CDM_DRIVER_DEFAULT, what does this mean? You have to return the
default values. Are the default values the "manufacturer default values",
so fixed values, that I can specify, or is this the values, that someone
set, by configuring the printer? (so the default settings for this
machine, the all users settings?).
Next question, about DrvDocumentPropertySheets... what's the "internal
DEVMODE structure" ? Is this the default structure for this user? Or for
the calling application? Or are this just the current settings for the
current process? Do I have to store them somewhere? Why?
And a more general question... who is responsible for storing the
systemwide default settings? Is this my driver? Is the "internal DEVMODE
structure" what represents those settings?
And the last question: I always thought, that this is the way it has to
go: 1) the application sets the current DEVMODEW structure by calling
DrvDocumentPropertySheets with DM_IN_BUFFER 2) the application lets the
driver to show the propertypages by calling DrvDocumentPropertySheets with
other parameters and 3) the application reads the changed DEVMODEW
structure by calling DrvDocumentPropertySheets with DM_OUT_BUFFER ... but
then I saw the line 855 in docprop.c (msplot sample of the ddk 3790) ->
pPI->pPlotDMOut = (PPLOTDEVMODE)pDPHdr->pdmOut; ... it stores a pdmOut
Pointer... and when applying changes, it directly stores the data into
this buffer... but I never saw this documented... can someone explain me
how this works?



thanks a lot
