A question about gdi functions for a print processor.
Hi
I'm working on a printer driver. ours is Unidriver-based driver.
I'm programming with the sample sources of a print processor that are in the
Windows DDK.
(\WINDDK\3790\src\print\genprint)
The sample sources already implemented a few printing features such as n-up,
reverse printing, etc...
i want to make a feature of manual duplex with the sample sources,
but i got a problem.
As you know, the manual duplex feature is that the front data of pages for
duplex is printed at first, and then the driver show a message box that
inform of the user to put the printed matters on the multi-purpose tray.
Finally, the back data of pages for duplex is printed.
So, i refered to the sample code amd made a linked list that store a page
information.
i used Gdi functions for a print processor such as GdiStartDocEMF() and
GdiEndDocEMF()....
but.. I got a problem..
the problme is that after the front data of pages for duplex is sent to
spooler,
i called GdiEndDocEMF() function to eject all the front data of page from
printer.
At that time, unforunately.. the emf data is deleted from spooler. T_T
although i called GdiStartDocEMF() to tranlate the back data of pages, the
return of the function is failed,(the GetLastErr() is 62)..
what function do the GdiEndDocEMF() replace to eject all data from printer?
how can i implement the maunal duplex feature in a print processor??
if you know, plz... let me know how to do or what to do....
thanks.

How to open this transport address
Hi,
I have tried to open raw ip in kernel mode "\device\rawip\255" or
"\device\rawip\17" (UDP) or "\device\rawip\1" (ICMP), all is OK, I can to use
it for sending packets.
Problem is that I need to open raw ip for TCP.
When I am trying to open transport address with device name for TCP:
"\device\rawip\6"
ZwCreateFile() returns 0xC000000D.
I am trying it with the same way like for above successful attempts, I pass
only different device name.
What is different in opening address for TCP ?
Must be set some different object attributes or something other ?

getting serial.sys to work for an ISA based 4xserial port card to work
I have an ISA based card with 4 serial standard serial ports(16550
type) that share an IRQ (using a cpld) that I would like to use with
windows 2K.
As far as I can understand it, i can use the driver included with
windows (serial.sys) and I need to write a wrapper of some kind and an
INF file. Is this a correct assumption ?
Are there any links to information that more or less outline the steps
to do something like this ? (as i have no prior experience with
developing kernel mode drivers on microsoft platforms.)
I would just like to estimate the difficulty of this job first, it
seems to me that it should be fairly simple.

multicast ping
My network driver supports multicast. I have tested with multicast

work at all? I am testing on Windows2003 server. Should I tune in additional

Page limit when using GDI to print
Although this is a client side issue, I believe the real issue is a
buffering limit in the printer driver. Since our Unidrv-based printer driver
is the first driver Iâ??ve ever worked on, I am curious if I am diagnosing this
problem correctly and if I understand all possible solutions.
We are experiencing a page limit when using GDI printing. After printing 85
pages from our application, we get a failure. We raised our Unidrv-based
printer memory limit to 2 GByte maximum and printing fails consistently on
the 86th page. This happens whether we print to an external printer or to our
Unidrv-based software PDF printer, i.e. a printer that creates a PDF
document.
When we print from our application using GDI printing, the return value for
the EndPage function for the 86th page is 0cFFFFFFFF, i.e. -1, and
GetLastError returns 0 (zero). We then call AbortDoc. If I modify the code to
allow printing to continue, only the first 85 pages are printed. The same
thing happens on an external printer.
Note, we do not believe that any pages approach the 350 MByte limitation
mentioned in the documentation. Also, if we delete pages at the beginning of
the document, then the document will still print only 85 pages, i.e. some
pages that previously didnâ??t print suddenly print.
Is the only solution to reduce the color-depth the 24 bit color images ouor
application produces, and of course, greatly reduce the size of the images
for gray scale or black and white printing? Then Ican modify the device
context to reduce the memory requirements for each page. Is there anything
else I can do?
If that is the solution, do printers typically use 16 bit color, 8 bit
color, or something else? We do need to be able to print photographs to high
quality printers, but the buik what our application deals with is black and
white documents. If those documents contain a color photograph we do want to
support printing that without such a small page limit. We've heard of
customer documents that exceeded 4000 pages! (Granted, these are quite rare,
but 1000 pages is no unheard of).
Thanks in advance.
P.S. Our printer driver is a Unidrv-based PDF printer driver, i.e. it
produces PDF files. It was built using DDK 3790. We support Windows 2000 and
Windows XP. It was developed using the Unidrv sample code provided in the
DDK.
The printer-generated PDF file is sent to an application we also have
developed, i.e. there is no hardware printer.
-------------------------------------------------------------------------
I posted the message above in the win32.programmer.gdi newsgroup in a post
titled "Page limit when using GDI printing.", and I received the reply below
from Rhett Gong [MSFT]:
Note however, despite his reply, that this is NOT just a Unidrv issue. It
happens when using GDI to print to other printers. I responded in that forum,
and included the calculation that shows that 2 GBytes will handle 85 8.5 inch
by 11 inch 300 DPI 24 bit color images.
(2 to the power 31) / ( (300 DPI * 8.5 I) * ( 300 DPI * 11.0 I) * 24
bits/pixel) ) = 85.0
This is what makes me believe the page limit is related to buffering in the
driver (or at least buffering somewhere).
The issue is that printing doesn't start until EndDoc() is called. Is it
reasonable to raise the driver buffering way above the virtual memory limit?
Is this data all mapped to a file?
I do not want to segement a 1000 page print job into multiple jobs as these
arrive back asynchronously from the Unidrv printer and are loaded into our
application. Having to append these over and over again would annoy most
users.
Note also, there are two separate issues.
1. GDI to other printers.
2. GDI to our Unidrv-based printer.
A solution to either of these would be useful.
Is this a fundamental limitation of GDI printing? (An answer to that would
help me to stop pursuing something with no solution).
-------------------------------------------------------------------------
Hello
From your description, you write a Unidrv by yourself, but you can only
print 86 pages and then EndPage return -1 and not further error code returned
. Based on my
understanding, this is a Printer Driver issue and require debugging into the
printer driver to find out the problem, so I would suggest you post this
question to following
newsgroup:
microsoft.public.development.device.drivers
It is a managed newsgroup. and all DDK issues and driver dev questions are
posted in the newsgroup above.
The reason why we recommend posting appropriately is you will get the most
qualified pool of respondents, and other partners who the newsgroups
regularly can either
share their knowledge or learn from your interaction with us. Also, this is
to make sure that the responders can better track the problem.

Synchronizing Timers and ISR
I am attempting to synchronize Timer procedures with the ISR. When my
timer expires it should perform operation A. If the ISR runs prior to
that it will perform operation B and cancel the timer. What I am
concerned about is the possiblity that the timer will expire, start
executing, and get interrupted prior to reaching the Critical Section.
In this scenario, Operation B will be performed by the ISR followed by
Operation A by the timer. Is there a method to prevent this from
happening? Thank you. Tag: How to check a driver is digitally signed through code? Tag: 72229

Correct DDK Windows 2000 SP4
I have Visual Studio 6, my O.S. is Windows 2000 SP4.
According to the MSDN order site the correct DDK for my system is the
Windows Server 2003 SP1 DDK, which I ordered.
My main interest in the DDK was to obtain the Usbview,c source code, however
Usbview.c will not compile on my system, it generates errors.
I have been told by a systems developer that I need the 'Windows 2000 DDK'
in order to compile Usbview.c on my system.
The 'Windows 2000 DDK' is now only available to MSDN subscribers and I am
not yet an MSDN subscriber.
If the above infromation is correct, can anyone here on the forum who has
the Windows 2000 DDK post back with the year(s) and month(s) of the MSDN
subscription CD that included the DDK.

Problems performing USB Isochronous/Bulk Read/Writes and unplugging device
Hello all, hello Mr. Roberts!
After clearing some general misunderstandings, maybe you could help me
once more with the second part of my former post. I would be very
grateful for your assistance.
I described it as follows:
>Depending on the pipe type I leave the dispatch routine forwarding the
>current Irp and device object to a validation routine for isochronous
>transfers (because they are more complicated) or bulk transfer
>completion routine. Isochronous completion is done as it can be seen

>transfers in the dispatch routine. Although I copied and pasted the
>whole algorithm from their (fine-working [standalone]) drivers, the system
>crashes when I try to perform a bulk/isochronous read or write. What
>rule did I violate?
Moreover I recognized the same crash behaviour when I unplug one or
both devices. I tried to get some debugging messages via DbgView from
Sysinternals, but the system crashes, without storing the information
into the given log file.
I checked the in- and decrements on the stack without result. They seem
okay to me. Since I solely introduced the validation routine for
isochronous transfer and sourced the transfer algorithm of the bulk
transmission out, I assume it must have something to do with the
parameters I forward to these functions. I appreciate your help in
advance, special thanks to Mr. Roberts who helped me this far. Tag: How to check a driver is digitally signed through code? Tag: 72211

Bulk and Iso-Transfers in one USB-Driver
Hi all,
I'm searching a reliable way to detect the pipe type of an IRP. I tried
to read this information like Microsoft did in their Bulk Driver Sample
from the DDK.
In the dispatch routine I check for upcoming idle requests. Then I get
the current Irp, the current file object, the pipe information and
that's where I get the current pipe type from. I understood that every
IRP stores information about what transfer type is at hand. Is that
right?
Depending on the pipe type I leave the dispatch routine forwarding the
current Irp and device object to a validation routine for isochronous
transfers (because they are more complicated) or bulk transfer
completion routine. Isochronous completion is done as it can be seen
the original sample. Microsoft did in their samples the validation for
isochronous and both validation and transaction in the case of bulk
transfers in the dispatch routine. Although I copied and pasted the
whole algorithm from their (fine-working single) drivers, the system
crashes when I try to perform a bulk/isochronous read or write. What
rule did I violate?
I'm through with W. Oneys book and the USB specification and the
firmware and the application. Although this work is part of my
internship and I'm (quite) new to this field I'm seriously trying to
get the best out of my work. I appreciate your ideas very, very much! Tag: How to check a driver is digitally signed through code? Tag: 72150

seems to take a pointer to a buffer (in_ptr and out_ptr), so if now I passed
address of an object of someStruct type, the how can I access data pointed

I have a need to access an SMBIOS interface which requires punching a
physical address into a CPU register directly and then writing an I/O port.
I was wondering if this interface could be converted to an ACPI op region
and avoid all of the non-standard, non-WHQL approved kernel calls that are
necessary to make this work?
I notice that their are two access types listed for these regions "cooked"
and "raw". The latest docs say "raw" access isn't implemented yet. I am
guessing this is what would be needed for this type of interface yes?
Originally, I was hoping that ACPI op region buffers were shared between
BIOS and ACPI op region registrars, but it appears that the data flow is
only one way, yes?
Any pointers on how these op regions work and even better how an SMBIOS
interface such as this could be accessed in a cleaner fashion would be much
appreciated.
BTW, for the sake of discussion assume I can modify the BIOS at will.

CDC interface for Composite (USB) device
Hello Everyone,
We have a composite USB device which contains a Line device (PSTN line)
and Telephone device. Each of these two device have two audio
interfaces.
I want to expose to Windows my composite device as Two communication
class devices - a) Line device (like a Modem) and b) Phone Device (CDC
spec - Telephone control model).
a) I would like to know if Usbser.sys will support this or do I have to
write my own driver?
b) Also what are minimum interfaces required by usbser.sys?
Thank you,

Hibernation problem for USB device without ROM firmware
We make use of a USB device that gets its identity changed dynamically after
the firmware is downloaded by our driver. The device has a unique VID and
PID that is used for the two sets of drivers. The first VID & PID are
burned into the ROM and it is not the USB chip manufacturer's VID/PID. I
have searched through the archives and found a similar issue discussed along
with a workaround suggested by Microsoft. (Attached below)
Our device is not quite as schizophrenic since it has our own VID/PID before
the downloading of firmware.
Anyway, I preferred to test the second design for hibernation so I created a
compound device with a hub. I installed a lower filter driver to our hub
and tried to download the firmware during power up, but I found that the
request (IOCTL_INTERNAL_USB_SUBMIT_URB with URB_FUNCTION_VENDOR_DEVICE)
fails with STATUS_DEVICE_POWERED_OFF when I download the firmware before
calling PoCallDriver (this is an experiment and what I expected).
Also I get STATUS_DEVICE_NOT_CONNECTED when I download the firmware after
PoCallDriver and this is not what I expected. It seems to me from my
experimentation that this is not a realizable solution.
I realize this suggestion was made "AS IS", but I was wondering if the
concepts have ever been tested or what I might be missing?

I brought to our PNP developer's attention nasty driver design issues
people
are running into with reprogrammable PCI (FPGA/DSP) and USB devices.
We saw
couple of those in recent days (Triggering a PCI bus re-scan) in this
forum. Here is his response:
**********************
Our customer needs to be warned that this type of hardware may not be
productizable.
The design (a reprogammable PCI FPGA chip that disappears and
reappears as
another device) is similar to some of the USB programmable DSP designs
we've
also seen problems with. Both of these designs run into major problems
with
PnP and Power Management.
Problems
--------
Identification
- In its default state, the device usually exposes generic "DSP/FGPA"
IDs.
An INF targets those IDs and specifies a driver that'll transform the
hardware into something else. If two different hardware vendors each
use the
same reprogrammable chip, their INFs will both match against the same
DSP/FGPA IDs. The OS doesn't know which driver to pick. Even better,
insert
a card from each vendor - mayhem ensues as one of the cards will get
the
wrong payload.
Power Management
- During power management operations (hibernation, suspend, etc), all
power
is often removed from the chip. When this happens, the chip typically
loses
its new identity and reverts back to its DSP/FPGA form. To the OS,
this
appears to be a surprise removal (the card disappeared). All the
handles
opened by applications against the device will go dead. The
application
might reestablish contact when the original device appears to be
"reinserted", ie the load sequence has repeated, but there is no
gaurantee
of this.
Plug and Play
- Some Plug and Play operations may result in power loss (rebalance),
leading to the problem above. Updating the driver also temporarily
places
the hardware in D3. Depending on the bus, this may result in a state
loss,
causing the device to "disappear" just as the OS is planning to reload
the
new drivers. A reboot popup may result from this.
How To Make FGPA/Reprogrammable-DSP Designs Work
------------------------------------------------
The best designs simulate a bridge/hub with devices behind it. For
instance,
the following design of a PCI FGPA works properly with Windows: 1. The
PCI
FGPA simulates a PCI-to-PCI bridge. 2. The PCI FGPA logic retrieves
the IDs
for the bridge from an EEPROM, ensuring no possible overlap with other
customers using the same chip (the IHV is expected to contact the PCI
SIG
and retrieve such IDs.) 3. The INF for the FGPA specifies PCI.SYS as
the FDO
(using NEEDS and INCLUDE directives to reference machine.inf as
needed), and
specifies a lower filter driver that will deliver the payload. 4.
During
IRP_MN_START_DEVICE, the filter driver downloads the payload to the
FPGA.
The FPGA now appears as a bridge (same IDs) with a *child* behind it.
The
child represents the IHV's device. 5. After start, the OS enumerates
the
bridge. Since the child is present, the OS loads the next set of
drivers. 6.
During powerup from suspend or hibernation, the OS first powers up the
bridge. The filter driver takes this opportunity to reapply the
payload if
necessary.
Here is a similar design for a reprogrammable USB chip:
1. The USB chip simulates a hub.
2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM
3. The
INF specifies USBHUB.SYS using NEEDS and INCLUDE directives targeting
USB.INF. The INF also specifies a special lower filter driver to
download
the payload. 4. During IRP_MN_START_DEVICE, the filter programs the
USB chip
to appear as a hub with a device behind it. 5. After start, the OS
enumerates the hub and discovers the child.
6. During powerup, the OS always powers up the hub before the child.
The
filter reapplies the payload during hub powerup.
And another USB design:
1. The USB chip simulates a *composite* USB device.
2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM
3. The
INF specifies USBGCCP.SYS via NEEDS and INCLUDE directives (similar to
above).
4. During IRP_MN_START_DEVICE, USBGCCP will read descriptors from the
hardware to determine which functions are exposed by the composite
device.
The driver (a lower filter) would reprogram the hardware to specify
child
during Start, before the IRP reached USBGCCP.
5. During powerup, the driver would reapply the payload as needed.

Supporting IAMStreamConfig with AVStream driver
I'm just getting started on an AVStream driver and would like to
support the IAMStreamConfig interface for the purpose of getting and
setting the data format (framerate, size, etc.). Which property set
must be supported for this? Also, will supporting this interface
result in the Video Format tab of the pin properties being activated?
(Don't worry, I'm not going to leave the default property pages in my
final version, but I'd like to get them working for now.) Tag: How to check a driver is digitally signed through code? Tag: 72126
printer port monitor question re: drag-n-drop install
I've got a question about port monitors and drag-n-drop printer installation.
When you drag a printer from a server to a workstation, what happens to the
port monitor that the printer driver(on the server) is using?
Fron the printers folder, clicking on the printer's Properties/Ports tab
shows the printer on the workstation is using the same port as the printer
on the
server is using.
However, if you do File/Server Properties from the printers folder and look
at the ports tab, the port is nowhere to be seen. If it's a non-standard
port monitor (ie, not included with windows), the port TYPE isn't even there.
(and you can't configure the port)
So what port is the workstation printer actually using? Is this documented
anywhere?
I am especially interested in any information regarding user-written port
monitors in this situation.
Thanks,
ScottR

Q: USB SCSI, announce media change?
Ok, I couldn't find a better place to post this question, so here goes!
I'm writing code for a device that exposes a removeable media drive. So
far, no problems getting Windows to see the drive, notice that there's no
media, etc. - however, when I change media Windows will redisplay the
contents of the old media!
I'm returning a CHECK_CONDITION with a sense code of 0x28 and a qualifier of
0x00 to TEST_UNIT_READY, which based on my reading of the SCSI spec should
tell Windows that the media might have changed.. but Windows won't reread the
device directory. Is there something else I should be returning here?
TIA for any assistance, this is driving me nuts! Tag: How to check a driver is digitally signed through code? Tag: 72113
How to translate glyph pathes into other font matrix?
I need to take the path of a glyth and translate it for the current font
matrix (True Type 2048y2048) into an other matix. I have tried some
calculations, but without success. Can someone give an idea where to
look at or what is to do?

plug and play hooks
Is there a way to hook the plug and play process? We want to stop the plug
and play dialogs from coming up and instead automatically point the process
to a directory on a server to pull the driver down. Is there any
documentation for doing something like this or is it even possible.

Print Authentication
Hi,
I have three printers one HP and two of Epson. I am interested in
coding a print authentication system. The idea is to popup a dialog box
for asking username/password. The problem is that I can use
DrvDocumentEvent for pop-up the dialog. But since it is placed on the
dirver UI code - I dont have access to the proprietary code, So I cant
do any changes into that. Is there any way I can achieve the popup of
the dialog box, no matter what printer is used from which ever
application.
PLease help. Your advise will be helpful for me.
Thanks

Driver Signing
Hi,
I'm working on the USB driver which is given to me from a vendor. Its
suppose to work with Virtual com Port. Now when driver signing is required,
is it only the USB driver which is given to me by the Vendor that should
undergo testing or is it along with the VCP . ? Tag: How to check a driver is digitally signed through code? Tag: 72103
Using Libraries
I want to create and use a DRIVER_LIBRARY. Note that this is to be a
statically linked library. Do I need to add special declarations on
functions that I intend to export?
Similarly, do I need to add any special declarations to the function
prototypes in the user code?
Thanks in advance,
Dennis
By the way, I've tried this out (without any special declarations), and the
linker kicks out an unresolved external symbol error for all the referenced
library functions. Tag: How to check a driver is digitally signed through code? Tag: 72101

Use of USBD_START_ISO_TRANSFER_ASAP
Could I find out the latest situation re the use of this flag - I've seen
talk of a bug in XP when using it but don't know if it is (a) still present
and (b) also a bug on high-speed as well as full speed devices.
I want to queue up multiple isoch URBs in my driver, but when I use this
ASAP flag approximately every other URB seems to be coming back empty (though
neither the URB itself or the packets within it are indicating any error). If
I try to manually precalculate the start frame for each URB then I get a much
more constant flow of data, albeit with some occasional
USBD_STATUS_ISO_NOT_ACCESSED_BY_HW errors [what causes these?]. I have approx
600 1KB packets in each URB.
