Re: Screen Savers - Do they serve any purpose anymore?

Thats a classic. Seen that as well.

Meeting takes place, data is presented (Excel / Powerpoint / etc.) and when they leave for lunch, they leave everything turned on, on full brightness, with no screensaver.

At my former school, you still can read last years grades in one of the tech-labs, where the teachers had their grading conference.

Cheers,
Sebastian

Thanks All

Clearly they still perform a role. I must have been lucky with the various monitors I've had over the last ten years or so that have survived without a screen saver.

Security mostly. We don't have children, but at home when friends visit with children I always turn on the password protected screen saver.

Also some people have cats that run amok over the keyboard so they set a screen saver for the same purpose.

In an office it could be useful for the same purpose.

Please, help me!
Has anyone seen The Complete Idiot's Guide to Writing drivers?
Yes, I know that the book doesn't exist yet (and, maybe, it will never be published).

But, according to articles posted here, at Codeproject...
I want to write my own usb-driver for my PocketPC (it has 1 usb-host). Can you advice me some good articles to read?

leagle / complience question

Can anyone comment on the legality and compliance of the following scenario?

I am interested in selling some hardware as part of a new VoIP project IO am working on. I have in mind using some hardware that is actually manufactured by another company but they do not sell it in the form factor that I want. Their stuff is a desktop stackible box and I want it to be rack mountable.

I am considering gutting their box and remounting the hardware in a 19" rack mount chassis the re-branding the whole thing with my company name and logo.

Questions/comments (some thinking out loud here).

1) Is this legal? I mean form a patent standpoint? The original hardware really has no company markings on it making it simple to just re brand it anyway. I will be buying it so I don't really see any difference that might make it wrong. Not really sure what the impact of buying and reselling vs. buying repackaging and reselling. I COULD simply mount the entire thing into a 2U case instead of gutting it and using a 1U case but that is wasteful.

2) I figure that I would have to get the assembly re certified for things like FCC and CE (ESD and emissions type stuff) right?

3) I also figure that by doing this I have forfeited the original equipment warranty so I will have to take that responsibility on myself.

4) I figure that I would set up an account with a recycler to take care of the original plastic and metal chassis parts.

5) Does anyone think there is a chance that the company would consider selling me the guts (sans the case) for maybe a lesser cost? Never considered that really. Hmmm

1) Depends on the law you are subject to. Basically, why don't you ask the original manufacturer?

2) Yes. I do not no for sure about the FCC-cert, but for the CE-cert, yes.

3) Yes, because you have your logo on it - and you are responsible for the "ESD/emissions type stuff" now.

4) Good idea. But you could always let it pile up in the corner of your workshop and then accidentally set your whole business on fire...

5) Possible. After all, if they sell to you or someone else does not really matter. Plus they do not have to care about the warranty for the machines you bought. And they still are gonna have almost the same profit margin.

Ask em, nicely, and good luck Smile | :)

Sebastian

If you plan on selling a number of units it would be advantages to contact the original manufacture for a volume discount. While you have their ear, ask about buying just the equipment you need, Right now your paying for hardware you flat out don’t need or want.

If they scoff at all, it might be wise to consider another source, there are plenty of manufactures out there and most are concerned with selling their goods, not what you do with them.

I know that there is something from my former ISP called "T-Online DSL Monitor". That will, on request, download a few megabytes from servers all over the world and tell you the individual results and averages.

You should ask your ISP if they offer something similar.

And always remember: It does not matter how fast your connection is if the server you are accessing is connected via ISDN Wink | ;)

Hi,
I am using alarms in my application ...But as i have to test the application,the app alarmed for each time.
I dont want this...I have to switch off the system sound..I use scheme box in sound control panel,i seleect No sounds..but it does not work.
Wat can i do?

What language / version and how are you playing the sound?

With out this information no one can help you.

All else fails; turn the volume down on both the speakers and the master volume down.

If I may be so bold, if you don’t like the volume of your alarms what make you think that your end users will?

I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

CBM-1000 II printer and communication with C# 2.0

Member 7610947-Jun-06 1:05

Hi all.

I cant understand what`s wrong in my code...
I`ve got "Command Reference" of Citizen CBM-1000 II Line thermal printer.
For example, cutting the paper:

[Command] (1) GS V m .......
[Command] (2) GS V m n ..... 
[Function] Cutting the paper
[Code]  (1) <1D>H<56>H<m>
        (2) <1D>H<56>H<m><n>
[Range] (1) m = 1, m = 49
        (2) m = 66
            0 <= n <= 255
[Outline] Performs the specified paper cutting.
Value of 'm' ----    Function
1 or 49      ---- Partial cut (Leaving a bridge area uncut)
66           ---- Paper feed by "cut position + {n ´ basic calculation
                  pitch}"and partial cut (Leaving a bridge area uncut)

Here`s my code (C# 2.0):

<br />
            SerialPort printer = new SerialPort("COM4");<br />
            printer.Open();<br />
            byte[] buffer = new byte[3] { 0x1D, 0x56, (byte)1 };<br />
            printer.Write(buffer, 0, 3); // printer.Write("GS V 1");<br />
            printer.Close();<br />

Printer do not cut the paper. Just printing some symbols...

What`s wrong here ?
Please help.

You probably have to set the printer to a special mode that interprets the data instead of printing it.

This could either be done by setting a pin, sending a special sequence or changing a setting on the printer manually.

I did it ! Smile | :)

But from code:

SerialPort p = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);<br />
p.Open();<br />
Stream s = p.BaseStream;<br />
byte[] buff = new byte[7] { 0x1D, 0x28, 0x41, (byte)2, (byte)0, (byte)2, (byte)2 };<br />
s.Write(buff, 0, 7);<br />
s.WriteByte(0x1d);<br />
s.WriteByte(0x28);<br />
s.WriteByte(0x31);<br />
s.Close();<br />
p.Close();

This basic code will print test page and then cut the paper.

I am in the market for a dedicated server company. The specs have to be good (at least P3 or P4 with lots of hard disk space) but most importantly, I need lots of bandwidth for a good price. Any ideas?
