There is no such thing as non-readable data if you can access the file; it just depends on how you read it. What are you using to edit the file? Swapping out a bit of text shouldn't increase the file size by 6k! You mention streamreader, Binary reader, etc, so I assume you're writing your own editing app. What language are you using? There are some interesting differences in the way various languages handle text - you may be getting invisible CRLF characters appended to your edits, for example, which will totally screw up the file format. A little more detail would be helpful...

Iam Using c#.net,I made the following 2 methods for it
First Method:
public void writetofile(string JobOwnerName, string genfilename)
{
try
{
string fileContent = string.Empty;
string NewOwnername = "@PJL SET JOBATTR=" + '"' + "@JOAU=" + JobOwnerName + '"';//@PJL SET JOBATTR="@JOAU + JobOwnerName + "
string strTextFileName = genfilename;
string strTextToInsert = NewOwnername;
ArrayList lines = new ArrayList();
StreamReader rdr = new StreamReader(strTextFileName);
//String search_str = "%-12345X@PJL JOB";
//String search_str = "%-12345X@PJL JOB MODE=PRINTER";
String search_str = "@PJL JOB MODE=PRINTER";
string line;
string s = "@PJL SET JOBATTR=" + '"' + "@JOAU=";
while ((line = rdr.ReadLine()) != null)
{
if (line.StartsWith(s))
{
lines.Remove(line);
}
else
{
lines.Add(line);
}
}
rdr.Close();
lines.Insert(lines.IndexOf(search_str) + 1, strTextToInsert);
StreamWriter wrtr = new StreamWriter(strTextFileName);
foreach (string strNewLine in lines)
wrtr.WriteLine(strNewLine);
wrtr.Close();
}
catch (Exception ex)
{
}
}
2nd method:
string JobOwnerName = "suman" + '"';
string path = @"C:\D.prn";
string temp = @"C:\DD.prn";
string test1 = "@PJL SET JOBATTR=" + '"' + "@JOAU=" + JobOwnerName + '"';
string s = "@PJL SET JOBATTR=" + '"' + "@JOAU=";
string line;
StreamReader sr = new StreamReader(File.Open(path, FileMode.Open));
StreamWriter sw = new StreamWriter(File.Open(temp, FileMode.Create));
while ((line = sr.ReadLine()) != null)
{
line = sr.ReadLine();
if (line.StartsWith(s))
{
line = line.Replace(line.Substring(line.IndexOf('"') + 7), JobOwnerName);
sw.WriteLine(line);
sw.Write(sr.ReadToEnd());
break;
}
else
sw.WriteLine(line);
}
sw.Close();
sr.Close();
----------------------------------------------------------------------
Sir,
Kindly go through the above methods I have developed..
Kindly help me Iam waiting for your favourable reply

I guess your problem is the replacement of linefeeds and newlines with an incompatible alternative. You know, just like you have to choose "ASCII-Transfer" in your FTP-Tool so that notepad.exe can show the config-files of your linux-server correctly.
You need to preserve the whitespace. Try reading binary, replacing a single letter, then writing the otherwise unchanges binary result back to a new file. You have reached your goal as soon as the two files afterwards are of the same size.
Cheers,
Sebastian

Hi all,
I recently got a hold of a USB bluetooth dongle and have been able to interface it with a phone to transfer media. Very cool. But as a huge nerd my next thought is "What else can I do with this thing?"
I'd like to be able to get another dongle and just run information between two points. This is a stepping stone for another group of wireless projects that are in mind, but the basics need to be covered first.
So I have a bank of questions that hopefully lead me in the right direction:
The dongle I have came with drivers to run the device. Things like bulk transfers, file transfers, pairing with different device profiles, everything. There's an interface that can be brought up that lets you connect to devices that you've trusted in the past. I understand the hardware inside the dongle could be nonstandard. Is there a way for me to get at the code in these drivers and see how these types of operations are done?
The device is obviously a USB device, so info and commands should be able to be sent to the port itself and whatever hardware is attached to it. Haven't seen much in the way of sending data to a USB port. Any help there?
Finally, short of any other solutions, is there some kind of development kit out there that allows complete noobs like myself develop applications to send information off the wire?
Thanks a ton for your time--I really appreciate coming on here and getting answers for obscure questions 
Take care,
Michael Fritzius

I look forward to seeing what replies you get - I'm clueless, too. I've got a Motorola 'Bluetooth Enabled' phone, and I can think of a lot of things to do with it. But the only thing I can find that is supported is a wireless connection to a headset. When I got it I had hoped to find a Bluetooth adapter to give me a port on my computer so I can code things like address book replication, autodialing using my PC mouse, GPS access. etc. But so far I've found nothing but headsets...

I look forward to replies too. Didn't want to post in a more frequented forum and be way off topic though so who knows when someone will give an answer
Also, I tried that same kind of operation with my phone. I've got a Samsung C417 and it turns out that the bluetooth on that phone has been crippled down to only operate with the headset profile. My wife's phone does all the fancy stuff that I wish my phone did. Perhaps your Motorola is of the crippled down variety. Do you have a way of testing against another dongle or something on another computer?

No, I haven't even found a dongle. And I have no reason to expect that Motorola included anything useful in the phone's firmware. I suspect that if I want to do anything useful, I'll have to write it myself. Still, it would be fun to experiment with, if only I could find a device to communicate with.

Hey Roger. There's a bit of a problem with Motorola Phone and Bluetooth. Apparently, they didn't do a good job of implementing the Bluetooth standards. It's only partially complete and really doesn't support much beyond audio/mic profiles, depending on the phone.
Where did I find this out?? A hearing aid manufacturer, of all places. They make a Bluetooth adapter to interface between hearing aids and cell phones. They told me their box works with just about every phone that supports Bluetooth, EXCEPT Motorola's! Then they went into a little bit of an explanation of why. It was very disappointing.

Hi Giorgi,
Thanks for the links. I got to looking at your stuff and other things that are similar. I think it has got me pointed in the right direction but I'll need time to figure out the code.
If I have any other questions would you mind if I email you directly?
Thanks,
Michael Fritzius

Feel free to e-mail me, though I am not a bluetooth expert. My application just uses libraries I found in the web. I suggest you have a look at the forum I posted for bluetooth and .net integration.
Waiting for your e-mails

Hello Experts!
I have ASUS Lightscribe DVD Writer. I want do the Lightscribe Label Plz guide me I have some doubts....
1. For that Normal CD/DVD is need or anything special CD/DVD Required ?
2. After Completed CD/DVD Burn turn CD/DVD and Burn once again for Label Is it right or not ?
3. Can i use complete space for burning or Lightscribe label deserved some space ?
4. Any design tutorial is for Lightscribe label plz give Website Name.
Thanks in Advance.

1. Yes, lightscribe requires special CDs/DVDs.
2. That is correct. You need to turn the CD once. As far as I know, you burn first, then label later, because the labelling-process takes VERY long.
3. That probably depends on your DVD Writer. I believe that the coating for the lightscribe-labels covers the whole printable area - but I might be wrong.
4. You are using a monochrome labelling technique. This means, you will design greyscale-images, which will appear in the color-hue that your lightscribe-medium offers.
Cheers,
Sebastian

Yes, the blank media you buy must support LightScribe.
non-bugging Errors wrote: 2. After Completed CD/DVD Burn turn CD/DVD and Burn once again for Label Is it right or not ?
After you burn the data on the disk, you flip the disc over to burn the label. This can take anywhere from 30 to 60 minutes to do, depending on the image.
non-bugging Errors wrote: . Can i use complete space for burning or Lightscribe label deserved some space ?
Yes. LightScribe uses the entire label-side of the disc. I've never seen a disc that supports a partial label.
non-bugging Errors wrote: 4. Any design tutorial is for Lightscribe label plz give Website Name.
There are no tutorials. The burning software you use has to support LightScribe and will walk you through the process. The only thing you have to do is make sure the image you use has enough contrast in it to look good on disk. I suggest using some photo editing software to make a grayscale copy of the image, then increase the constrast. Use the grayscale image as your disc label.

Are there any current-production drives which can draw pictures on the content side of the disk, the way Yamaha's CD-RW drive could? The results were pretty feeble with some types of media, but really cool with some others. Cooler-looking, IMHO, than those produced by LightScribe. Unfortunately my Yamaha drive quit working or else I'd keep using that.

I've recently reread some older magazine, and they wrote that "Labelflash" was based on "DiscT@2" / DiscTattoo, which was how Yamaha called their technique before they stopped manufacturing CD/DVD writers.

I have a DiscT@2 drive, but it quit working. From what I can tell, the LightScribe drives won't work unless they see a special pattern marked on the disc; that pattern only appears on the non-data side of LightScribe brand media.
I wouldn't be surprised if there's a technical limitation there, but I did enjoy the DiskT@2 feature and would like to have a drive that could do it.

Hi developers!
I'm developing a bluetooth application which connects a pocket pc with a pc using a bluetooth serial port. But when i'm trying to create a bluetooth serial connection with my pocket pc, it says, that the service is not available for this device. My device is shown as a smartphone, if thats important..
But why can't you create a bluetooth com port from a PC to a Pocket PC, when i can from a Pocket PC to a PC?

Anyone has any idea of a controller card thats 12 port LP-FF?? I was looking for one from a long time and couldn't find one... I have a 2U chassis that has 7xLP expansion slots.
If not, how can I use all the 12 drives using one controller, the on board controller is only 8port and is SR.
thanks

Hi, All:
I have been developing the KMDF Mode USB device driver for the USB Full-Speed(USB 1.1) device.
I implemented the simple USB functions into the device. The device has one interface and one Interrupt IN endpoint. And it is a vendor-specific class device.
I also developed the KMDF Mode USB device driver for the device.
The device was enumerated with the driver normally and the continuous reader was polling the Interrupt IN endpoint periodically.
But, I noticed that the polling interval is different from the one that I expected. (I used Windows XP SP3 for the evaluations.)
I also checked the contents of descriptors with the USB protocol analyzer. But, they seemed to be correct. I also monitored them with WinDbg. The driver seemed to get the same decriptors as the device correctly.
There were the following relations between the setting value and the actual value for the polling interval.
Setting Value : Actual Value
20 msec : 15.999 msec
100 msec : 31.998 msec
255 msec : 31.998 msec
Does the KMDF continuous reader support the USB full-speed devices?
It is helpfull for me if someone could tell me how to solve this problem?
Thanks.
Yama Fuji.
