 - PCL to EMF How can i convert PCL to EMF, is there a way so that i can program this. Similar to this I am keen to know if I could convert Postscript(PS) to EMF with out depending on Ghostscript. Basically i would like to render PCL or PS files in my VC++ programs and try to extract the text from it. I am not bothered about the graphics with in these files and only bothered about the text with in. Somebody please help me with this. Thanks... Tag: Thread Safe Tag: 70813

 - scsi rescan caching Hi, Regarding the Microsoft own rescan.exe, as found at: http://support.microsoft.com/default.aspx?scid=kb;en-us;308669 I have found this very utility and particulary the CM_Reenumerate_DevNode() call, which is used within to do actual bus rescan, are behaving as if there is some caching involved. Test as follows: 1. run rescan over and over, from command line, as fast as you can (or write a shell script to do it) 2. Observe how long does it take, each time, for rescan to finish You will see the very 1st rescan does take some time to finish while all subsequent are returning IMMEDIATELLY. Then again, after 30 or some iterations, rescan AGAIN takes some time, as if it actually doing something. I made no device additions in that time. Machine was idle. Test is reproducible. Note I did above test with both NORMAL and CM_REENUMERATE_SYNCHRONOUS setting for CM_Reenumerate_DevNode(), same behaviour. Any thoughts on this? Thanks, Robert Tag: Thread Safe Tag: 70808

 - "build" not showing all build - fixed Several months ago, I noted that the DDK "build" utility would in some cases NOT show all errors encountered during a build. I have today found out that this is a side effect of installing the Windows DDK to a path containing spaces. Moving the DDK to a space with no spaces, allows all errors to appear as expected. If anyone is interesting in troubleshooting the DDK build utility, here's a quick way to reproduce it: 1) install DDK to C:\Program Files\Windows DDK 2) drop the 3 files listed below into C:\temp\ 3) Launch a build environment DOS window (in my case Windows 2000 checked) 4) in directory c:\temp, type "build -cZ" ==> The only error shown is an *.obj file missing. The *.log file, however, lists lots and lots of errors. Here are the files I used to reproduce the issue: makefile ========= !INCLUDE $(NTMAKEENV)\makefile.def sources ========= TARGETNAME=temp TARGETPATH=obj TARGETTYPE=DRIVER C_DEFINES=-DNDIS_MINIPORT_DRIVER SOURCES=temp.c temp.c ========= #include <ntddk.h> #include <ndis.h> NTSTATUS DriverEntry( IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath ) { return STATUS_SUCCESS; } Good luck! Maybe one of these days the DDK will allow people to use spaces in their paths & filenames.... :-) / Hannes. Tag: Thread Safe Tag: 70804

 - uDAPL on Windows? I need to write a driver for a set of PCI-Express boards and there has been a request for supporting uDAPL as the API for interacting with this hardware. The implementations of uDAPL on windows that I have seen appear to be in their infancy and there is a surprising lack of information out there describing what a driver needs to provide for services in order to support this API. Can anyone point me to either some really good documentation or tell me another API that is more "at home" on Windows that would accompliush the same thing (an RDMA type of aAPI). All the uDAPL stuff I have seen has been geared toward Linux support with windows being an afterthought. Thanks, Beverly Tag: Thread Safe Tag: 70799

 - Problem writing extension unit plugin. I am writing an extension unit plug-in for a USB video class device. The example that I have used as a template, is the Microsoft provided example at [http://www.microsoft.com/whdc/device/stream/vidcap/USBVid-ext.mspx]. I have experienced quite many problems with this example, the IKsNodeControl described in the example can't be found in any new SDK or DDK, only in DirectX SDK from 2004.

 - Is it possible for the mirror driver does not support DrvBitBlt function? I'm writing a mirror driver based on the DDK mirror driver sample code. I read the documentation at the msdn library, and learned that if a driver manages its own surface, the driver must also, at a minimum, support DrvCopyBits, DrvTextOut, DrvStrokePath drawing functions. I noticed that DrvBitBlt was also in the DDK mirror driver sample code. When I hooked off the DrvBitBlt function, I got a blue screen. I'm trying to avoid implementing DrvBitBlt because of complexity. Could any guru tell if it is possible not to implement DrvBitBlt function in the mirror driver? Thanks, Tag: Thread Safe Tag: 70749

 - Problem uninstalling keyboard driver Hi, I've written a keyboard driver for W2K/WXP which ties in with kbdclass and works fine. It happily sits next to a standard Windows keyboard driver in Device Manager. Problem is Device Manager gives no Uninstall option for my driver and DevCon reports "Remove failed" if I try to remove it. I've also written a touchscreen mouse driver which similarly connects with mouclass and sits next to a standard Windows mouse driver in Device Manager. This does have an uninstall option and can be removed using DevCon. Both drivers have a similar structure, but is there anything extra I should be doing in the keyboard driver to make it uninstallable? How should I go about uninstalling it? Thanks, Ade.

 - Strange behaviour with USB selective suspend Hello I've connected a usb mouse in combination with our own usb device to the same root hub. Our device supports remote wake-up. The driver for our usb device sends down a request for usb selective suspend. Nothing happens. When I unplug the usb mouse, the system happely invokes the callback routine so the driver sets device power state D2. I find this behaviour a bit odd. Why does the usb mouse prevent our device from going into usb selective suspend? I also replaced the usb mouse with a different usb device but the behaviour remained the same. This is WinXP SP2. The implementation in our driver has passed whql. Tag: Thread Safe Tag: 70743

 - USB stack gives misleading indications when Polling Interval not 1 I am seeing some incorrect indications from the usb stack (XP SP2) when my device indicates a Polling Interval of 2 on its isochronous endpoint: My hardware has a high speed (not high bandwidth) iso In endpoint; it generates fixed size 1000-byte packets at an interval very slightly over 250uS. I have taken the isousb sample from the 3790 DDK, and adapted it to work with my configuration. Because of the data rate, it seemed sensible to increase the polling interval on that endpoint so as to only poll every other microframe, so I set a value of two. I use the test app (rwiso) to read an amount of data from the device, and the driver output is as follows: IsoPacket[0].Length = 0x03E8 IsoPacket[0].Status = 0 IsoPacket[1].Length = 0x0000 IsoPacket[1].Status = 0 IsoPacket[2].Length = 0x03E8 IsoPacket[2].Status = 0 IsoPacket[3].Length = 0x0000 IsoPacket[3].Status = 0 IsoPacket[4].Length = 0x03E8 IsoPacket[4].Status = 0 IsoPacket[5].Length = 0x0000 IsoPacket[5].Status = 0 IsoPacket[6].Length = 0x03E8 IsoPacket[6].Status = 0 IsoPacket[7].Length = 0x0000 IsoPacket[7].Status = 0 IsoPacket[8].Length = 0x03E8 IsoPacket[8].Status = 0 IsoPacket[9].Length = 0x0000 IsoPacket[9].Status = 0 IsoPacket[10].Length = 0x03E8 IsoPacket[10].Status = 0 IsoPacket[11].Length = 0x0000 IsoPacket[11].Status = 0 IsoPacket[12].Length = 0x03E8 IsoPacket[12].Status = 0 IsoPacket[13].Length = 0x0000 IsoPacket[13].Status = 0 IsoPacket[14].Length = 0x03E8 IsoPacket[14].Status = 0 IsoPacket[15].Length = 0x0000 IsoPacket[15].Status = 0 IsoPacket[16].Length = 0x03E8 IsoPacket[16].Status = 0 IsoPacket[17].Length = 0x0000 IsoPacket[17].Status = 0 IsoPacket[18].Length = 0x03E8 IsoPacket[18].Status = 0 IsoPacket[19].Length = 0x0000 IsoPacket[19].Status = 0 IsoPacket[20].Length = 0x03E8 IsoPacket[20].Status = 0 IsoPacket[21].Length = 0x0000 IsoPacket[21].Status = 0 IsoPacket[22].Length = 0x03E8 IsoPacket[22].Status = 0 IsoPacket[23].Length = 0x0000 IsoPacket[23].Status = 0 So this suggests that every other packet is coming back zero-length. However, when I look at the entire buffer from the user-space app there are no gaps - every piece of data *is* there (and correct) from beginning to end - all 24 packets. The return value from the read() call is 12*1000 yet the whole buffer has in fact been written. I've also used SnoopyPro to examine what the stack thinks the packets contain, and diagrammatically (and very much simplified), this is what I'm seeing (with "." indicating a zero-length packet): According to stack Actually in buffer 0 1 2 3 0 1 2 3 . 4 5 6 7 8 9 A B 8 9 A B . C D E F 0 1 2 3 0 1 2 3 etc This is a problem to me because I will occasionally get genuine zero-length packets (due to the data generation being asynchronous to the usb frames), and I need to be able to detect them. The USBD_SHORT_TRANSFER_OK flag is not set. This only happens when the Polling Interval is 2; when it is set to 1 then the behaviour is as expected (albeit interspersed with genuine zero-length packets, generated by the h/w when it is polled but has no data available) I'm running a free build XP SP2, but with checked versions of ntoskrnl, hal, usbport.sys, usbccgp.sys and usbd.sys (also from an SP2 version). Is it a bug in the usb stack? There is a report of this kind of problem - http://support.microsoft.com/?kbid=837371 - but although it is dated only a few days ago, it seems to be saying that the issue is fixed in SP2; and I have newer versions of all the files indicated (though why don't I have usbccgp.sys - isn't that needed for composite devices??) [I'm having trouble with my Win2K installation at the moment, so I've not had a chance to compare]. In fact, as I repeat the test today to check my results (before hitting "Send"), I'm *also* now seeing an additional effect: a packet with a length of 1000, but contents all zero - but, again, without any loss of data - where there *is* data in the buffer it is continous and valid (the data stream contains a count to help spot discontinuities). What with the results I was seeing yesterday plus this additional weirdness I'm now seeing, I'm wondering if there are still issues with non-one values of polling interval? Anyone got any thoughts? Can anyone at MS confirm whether 837371 really is fixed? Thanks. Tag: Thread Safe Tag: 70727

 - Converting Win2k monolithic printer driver to a Longhorn driver - Installation problems Converting Win2k monolithic printer driver to Longhorn driver - INSTALLATION Problems.. The current monolithic(not using Microsoft Universal Printer Driver Model) Windows printer driver has been converted to "user-mode" and installs/runs fine on Win2k, WinXP, and WinServer2003. However, for "Longhorn Beta1" the following error message is given during an attempt to install the driver: Error Message: "The driver that you are trying to install is not compatible with Windows Server 2003 family. Please contact the manufacturer for an updated version." It appears (according to the following windows log files: setupapi.app.log, setupapi.dev.log) that the installation (via the Add Printer Wizard) successfully copies the driver files to a system location, but immediately after that point, the error occurs and the installation is cancelled. I suspect that when the "loader" attempts to load a driver DLL (toward end of installation), it cannot resolve a reference in the DLL to some Win API function (NOT IN Longhorn), and therefore the DLL is not loaded. Normally, one would get some kind of error message that indicates a particular function could not be found/resolved; but this may not be the case while using the "Add Printer Wizard". I placed calls to "MessageBox(-)" at several "entry-point" functions in the DLLs (like DllMain, DLLInitialize, WinMain, DrvQueryDriverInfo, etc.) but these are NOT reached during installation on "Longhorn"; however, they are reached during installation on the other OS's. Any Ideas? Rudy Tag: Thread Safe Tag: 70716

 - USB Problem when using a Philips ISP1521 based hub We are using a TI TUSB3410 USB to Serial chip and recently identified an issue when using this device with a Philips based ISP1521 based Hub. On the USB-IF Developers Discussion Forum a post was made that matches our problem exactly. This post also has a statement that Philips apparently made which states the issue is that the Windows USB host controller driver. Basically Philips states that the host controller driver is not terminating Start Split transactions with a Complete Split transaction. For the original posting see http://www.usb.org/phpbb/viewtopic.php?t=6636&highlight=tusb3410&sid=92ad332153ccee7ed3babd646910e98d. We have been told by TI that Microsoft acknowledges that this is a bug and that it will be fixed in Vista. However in the meantime our customers are experiencing problems when using our hardware with ISP1521 based hubs. My question is, how can we work around this issue? Is there something we can do in our application or in the driver to cause the host controller driver to terminate the split transaction? Thanks in advance for any help in resolving this issue. - Steve - Tag: Thread Safe Tag: 70696

 - Several problems building the DDK USB-Drivers Examples under W2k BE Hello folks, I beg you to forgive my very little skills in developing drivers. So I'll report my problems right from the start and how I tried to solve 'em. I'm about to develop a USB-driver that implements Bulk-, Interrupt-, Isochronous Transfers. Getting things started, I intended to build the isochronous USB-Drivers from the latest DDKs (3790 & 3790.1830) and communicate with the self-developed device. I'm working on a x86, W2K plattform and because of upward-compatibility on a x86 XP. On both platforms I got the warning, that the existing sample would not be valid for the current OS target. I changed the makefile in looking after a platform >= 0x500, i.e. Win 2k. But problems went on. While the Windows Server 2003 BE builded the driver reliably, the Win2k BE brings up an error C1083: Cannot open include file 'usbbusif.h'. BUILD: Compile errors: not linking c:\usb\sys directory. I looked after the .h file and it appears in %WINDDK%\3790\inc\ddk\wdm\wnet and ...\wxp but not in the adequate w2k-dir. I copied the missing file(s) in ...\w2k but in the aftermath over 700, mostly syntactic errors occured while compiling. The syntax is correct. This sounds clear to me 'cos WNET-Build works fine. I restored the original dirs of the inc\ddk\wdm... I followed some tips in the newsgroup. Although I have no spaces in between dir- or file-names the error still occurs. I have no errors in compiling the test-programs to the usb-drivers of the ddk. I've consulted the DDK-docs, the newsgroups and Walter Oney's 'Programming the WDM 2nd ed.', but none could take me on the fast lane. Now YOU are my only help and I appreciate that very much.

 - Does IPMI driver support BT interface Hello, Our BMC provides both BT & KCS interfaces to the host. I have following questions in regards to Windows IPMI driver: 1. Does it support BT interface? I only see reference to KCS interface support in the documentation. 2. If it does support BT interface, can an application specify an interface (whether KCS or BT) for sending a command to BMC? 3. Can IPMI driver accept simultaneous commands from multiple callers and internally serialize these commands & responses?Does driver allow an application to register to receive IPMI commands from BMC and get event notification once such a command arrives from BMC? (Opposite of normal behavior, apps/Host send the IPMI commands to BMC). Linux OpenIPMI driver allows doing so. I will sincerely appreciate any help on these questions.

The following setup fails : total packages = 16578 bandwith = 4096 buffers = 15 I guess that the system either won't allow me to allocate that amount of memory, or there isn't enough memory left.

 - Suspend / Hibernate for PCMCIA device Hi all, I am writing driver for 16-bit PC-Card (PCMCIA) device for Windows XP, and currently facing an issue with Hibernate and suspend. When the machine gets Suspend/Hibernate state, the PCMCIA bus turns off our deviceâ??s power. If I set an error code for IRP_MN_QUERY_POWER, then the OS does not get into both states. (Pop up the dialog which informs our driver rejects the mode). I would like to get the OS to Suspend/Hibernate state and start using hardware when the machine wakes up. Does anyone know the way to keep PCMCIA deviceâ??s power during both modes? Our device is Multi-function PCMCIA device, so the base address should be re-written to the hardware once it turned on, PS: The returned value of QUERY_CAPABILIES from PCMCIA driver says that PowerStateSpleeping1-3, and PowerStateHibernate are mapped to PowerDeviceD3.

 - Creating an installer for a mirror driver Hi, I'm fairly new to driver development, so apologies if this is rather basic, or has been asked and answered many times before. I have a mirror driver that I want to create an installer for. I tried using DPInst, but it didn't add the driver to the Device Manager's list, so I would still have to use the "Add Hardware" wizard. Is it possible to create an installer for a mirror driver that will eliminate the need to use the "Add Hardware" wizard, and if so, could someone please point me in the right direction for how to do it? Everything I've found so far relates to drivers for new hardware, so doesn't seem like it will work for a mirror driver. Many thanks, Frances Tag: Thread Safe Tag: 70633

 - Can't set device interface registry data under W2K... Hi, I have a driver which uses IoOpenDeviceInterfaceRegistryKey() to open a device interface registry key and then uses ZwSetKeyValue() to write values to that key. The driver was originally written for and runs fine under XP. But under W2K, calls to ZwSetKeyValue() fail with 0xC0000008 (STATUS_INVALID_HANDLE) even though the IoOpenDeviceInterfaceRegistryKey() that preceeds it returns STATUS_SUCCESS. Any ideas? Ade.

 - custom keyboard driver I'm porting a software package from Win98 to WinXP embedded. The software runs only on special (custombuild) PC-Hardware. My problem is now that I have a special keyboard (connected to a custom parallel)where I have to read the scan and return lines cyclic and generate the keyboard input for windows. With Win98 I did this by programming the RTC to generate interrupts ~every 4ms on IRQ 8, virtualized in VPICD and unmasked it in the VPICD. In WinXP I didn't find a why to install my own ISR for IRQ 8! Is it possible to do so?? Or do I have to build a cyclic timer (KeSetTimer and so on). Does anyone knows a good code sample for polling every 5ms some hardware ports? bcp Tag: Thread Safe Tag: 70607

Yes, NDIS protects the pools passed to these functions against
corruption due to simultaneous calls.
