Yeah, but I hate repeating myself. I don't think his answer would have changed either.

Hi everyone,
I am exploring the possibility of plugging webcams/cameras (preferrably any webcam/camera - so I don't get tied to a particular hardware vendor) into a Windows Mobile 5 or 6 device, and write a piece of software app that allows user to click a button in that software app to get the plugged-in webcam/camera to take pictures or video streams.
So, I will need to know if this is possible to write a software app to do so on Windows Mobile 5 or 6 platforms? .NET is preferred but not essential.
What exactly do the webcam need to adhere to (for example, TWAIN)? USB Video Class 1.1? Bluetooth?
I had a look on the internet but no luck so far.
Any pointers will be welcome.
Thanks
p.s. I also posted the same message on Stackoverflow...

Hi I have a fair knowledge of electronics and have decided to under take my self a small project and build a multi function foot switch for controlling media players on stage for when im singing. I have made my prototype from an old usb keyboard and buttons removed from a old serial mouse. I may change this later date to use a usb game pad or even build a whole new board based on the PIC18F4550
Now here's the tricky bit I have a small app called RM-X media edition which allows me to assign any received input as a control, currently
SPACE - PLAY/PAUSE
1 - BACK
2 FORWARD
I picked these because they where easy and used the same common ground on the keyboard controller.
What im hopping todo is edit the standard driver files that windows uses for this device to allow it to show as its own device i.g "Soundshark foot switch"
The second part is to rename the commands as it is windows see the inputs as keyboard strokes I want to edit these again to read as there respective functions in the RM-X software.
I hope this is enough information and makes sense Any help at all on this matter would be fantastic.
Thanks Anthony

Hi,
I don't know enough to give you definitive answers, however here are some thoughts:
- as you are using a (modified) keyboard without any special driver, it is using the standard USB keyboard driver and I don't expect you can't do anything related to its name or its character table; it will show as whatever device the manufacturer decided it was (unless you can reprogram the microcontroller they used).
- as an alternative way to personalize it, you would need to create your own driver.
- I've done some PIC-to-PC interfacing in the past, using RS232C, not USB; I would be interested in learning how to do similar things with USB.
- rather than using normal keys, I would choose some of the function keys. That would much less disrupt your other programs. Or you could try and figure a way to get a key combination, say a modifier key (CTRL/ALT/SHIFT) and some other key; problem is you have to hold down one, press the other, release the first. You can't hold down the modifier key, that would really upset everything.

yeah may be the best option was just hoping to try and make it a stand aloan device, Only way i though about getting a round it using a standared driver was to install manually or selct update drive and selct my driver rarther then the installed one to superseed it
other option is to use a cheap usb gaming pad or as i said befor build my own controller from scratch if i can find a basic design 3 buttons would be plenty. Thanks for the help ill keep digging anything i find i shall post

I am trying to create an image of a Dell Poweredge 2950 server that uses a RAID 5 configuration. Is it possible to create an image from a bootable media that will recognize a RAID array? If so what are some software application that will do this? I can image the logical drive once the OS is running but I cannot re-image over the existing partition.

i am student who study device driver.
i don't understand blow source so i search DDK document but i can't understand.
can you explain line by line?
sorry to ask whole thing
HANDLE GetDeviceViaInterface( GUID* pGuid, DWORD instance)
{
// Get handle to relevant device information set
HDEVINFO info = SetupDiGetClassDevs(pGuid, NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
if(info==INVALID_HANDLE_VALUE)
{
printf("No HDEVINFO available for this GUID\n");
return NULL;
}
// Get interface data for the requested instance
SP_INTERFACE_DEVICE_DATA ifdata;
ifdata.cbSize = sizeof(ifdata);
if(!SetupDiEnumDeviceInterfaces(info, NULL, pGuid, instance, ifdata))
{
printf("No SP_INTERFACE_DEVICE_DATA available for this GUID instance\n");
SetupDiDestroyDeviceInfoList(info);
return NULL;
}
// Get size of symbolic link name
DWORD ReqLen;
SetupDiGetDeviceInterfaceDetail(info, ifdata, NULL, 0, ReqLen, NULL);
PSP_INTERFACE_DEVICE_DETAIL_DATA ifDetail = (PSP_INTERFACE_DEVICE_DETAIL_DATA)(new char[ReqLen]);
if( ifDetail==NULL)
{
SetupDiDestroyDeviceInfoList(info);
return NULL;
}
// Get symbolic link name
ifDetail->cbSize = sizeof(SP_INTERFACE_DEVICE_DETAIL_DATA);
if( !SetupDiGetDeviceInterfaceDetail(info, ifdata, ifDetail, ReqLen, NULL, NULL))
{
SetupDiDestroyDeviceInfoList(info);
delete ifDetail;
return NULL;
}
printf("Symbolic link is %s\n",ifDetail;DevicePath);
// Open file
HANDLE rv = CreateFile( ifDetail;DevicePath,
GENERIC_READ | GENERIC_WRITE,

I'm looking for resources on programming in machine/binary language so far I've only found resources on coding in ML on atari archives.So if anyone written any tutorials or found any ebooks on the subject please email them to alien.fx_fiend@yahoo.com.What I'm looking for is cutting edge and in depth analysis into the fundamental workings of a system and ML coding.

I don't know much about networking..
I can see a port in the back of my motherboard for connecting the LAN cable.
Isn't it enough for setting up a LAN??
What is an NIC card?
What is the use of it when the motherboard comes with the cable port.
I think the RJ45 is in the back of the board...
Is there any special use for using an NIC??

During development of a USB device, I temporarily used Vendor ID=547 and Device Id=1002, since those were the defaults for the development kit I was using. I have since switched to using properly-registered IDs.
Unfortunately, a product I have purchased and would like to use (a chip programmer) uses the same IDs, and any time I plug it in Windows wants to attach my drivers rather than the proper drivers for the device. I can easily enough see what devices are 'installed' and uninstall them, but the next time I plug in the device it installs it with my drivers rather than prompting for the right ones.
What must I do to tell windows that 0547/1002 is NOT my device and I would like it to prompt for a .INF file (which could then load the proper drivers)?

I have no clue to where windows caches the setting or files. Have you tried uninstalling your driver, purging the temporary files and removing any .INFs that match your description? Other than that, this is why default IDs are bad.
Cheers,
Sebastian

Since having written the earlier message, I've managed to delete the appropriate .INF files and pretty much convinced the system that my device doesn't exist under its old identity. I still can't get the new device to work, though. My guess is that it partially installed something in such a way as to get itself confused.
Sometime I'll reinstall the OS on this machine, and when I do I can fix things then.
In the mean time, I wonder how I should best contact/pester the device vendor. It seems that its .INF files contain both the default vendor/device id's and some other ones, but the device itself uses the default ones. Grrr....

I have some old manufacturing equipment that has 3.5" floppy drives.
I am wanting to replace the floppy drives with something else like a USB stick. I
must use the FDD interface because of the limitations of the equipment.
Are there any available products already available?
If possible, I would like to access the storage over a network connection also.

What do you know about the hardware/software in question? Do you need read/write access, or would read-only be sufficient? There exist SmartMedia-to-floppy interfaces which allow a SmartMedia card to be used as a very large (but still slow) floppy disk, but those unfortunately require the installation of special drivers. If you need something that physically looks to the rest of the system like a 3.5" drive, I would expect such a thing could probably be constructed with a small microcontroller, a CPLD, a flash chip, and some buttons and a display to switch disks. Sounds like that would be an interesting project; not particularly difficult, but I don't know if anyone's done it.

That device looks interesting. I'm a little curious, though, how it would work with devices that don't use a DOS-compatible file system. Something like an Ensoniq DSK just has three sample-storage areas per disk; push 1, 2, or 3 to select the area to save/load. It's conceivable that it might use a file system, but I think it's far more likely that it just reads a fixed range of tracks based upon the button selected.

If it's being honest about working almost anywhere I'd assume it emulates the device at a very low level... *IF*

The file format used by the equipment is FAT. The disks written by the equipment can be read on a PC and vice versa.
The equipment can format a disk and then be used with a PC.
