I am trying to send ATAPI commands to a cdrom in VB.Net. While researching this it seems to me the VB is not the best at this. I am sure their is a way though. Can anyone steer me in the right direction? I read something on calling the Windows API to do some hardware speaking, but it said that that is being Phased out with VB.Net.
I am able to send these commands through 2 other test programs that we use.
Thanks!

I am Sushanti, Msc Part 2 student from Mumbai, India. I have selected JTAPI as my project topic. Till now I have planned to add the following features in my project :
1) Making phone calls from PC.
2) Receiving phone calls.
and if possible
3) Conference
4) transfer
5) answering machine
I have downloaded JTAPI 1.2 class files. My java files are getting compiled successfully. I have doubts regarding the hardware
configuration required to run these. Will I be able to really make a call by using a microphone, speaker or even by using our modem. Is cost required for each call. Is a provider service is obligatory. How should I go ahead with this project if I won't be able to show the examiner the call really being processed. Need your guidance in this. Waiting for your positive response.

hello there
we did a similar project in VB for our final year engineering... you need a modem... a full duplux voice modem.... and ofcourse a phone line connected to the modem.... making calls through PC is like having phone instrument virtually in the PC.... call charges and others are same as that of using a phone... u wont need any special hardware..... actually you can show the examinar the real process like we did.... Note: remember we did our project in VB using TAPI... we have some dll's and ocx using that we did this project.... our project is an answering machine.... it is going to be implemented in our college... our project is like when a parent or some one calls this number the PC will pickup the call and ask for the detail they want, like college detail or student detail then the calling party can respond by pressing option number in their phone.. the software will read this signal called DTMF and then respond as per the option or choice dont worry this is simple and if you have any other doubts you message me........ my email id is urdreammaker@rediffmail.com

You're taking on a huge project for a student, but it can be done. I think you may have found a great resource in Madhu - he's been there, done that. I found TAPI utterly baffling when I attacked it with VC++ and the MFC classes, but the Java community has done a far better job of implementing classes for communications of all kinds than Microsoft has ever done. I would certainly embrace any ideas that Madhu offers and run with them. Spend some time on the Sun website, too. They offer some very good tutorial material and sample code, if you can find it. The website isn't organized as well as it could be, but it's an excellent resource. Best of luck to you....
BTW - When you're done with this project, it will be a great article to post here to help others learn from your experiences.

hi
Tapi is difficult but possible and i have used ocx so it was quite easy like wise you can refer for helps in jtapi which will help you a lot.... you will be able to finish your project only if you try using available functions... if you try to implement functions then that itself will become a project........ take care

In your opinion, what is the best laptop for programmers? What attributes make a laptop better suited for programmers?
Currently, I have a Thinkpad T40 and find it more than adequate. Getting a little old though, so I thought I would ask.

Look for a fast hard drive (7200 RPM  ) and 64-bit CPU (Athlon 64). I'd recommend such a notebook b/c a fast drive will make all trivial tasks like compilation, DB access etc finish faster and a 64-bit CPU will ensure building/using newer 64-bit OS and apps. Oh, get lots of RAM.

It should be very comfy to sit on, and have great patience for being ignored for hours at a time. It should be happy to disappear once in a while to clean house, pay bills, and - ideally - cook an occasional real meal rather than sending out for pizza. Judging by many of the bio pics here, it should also be fairly large, in order to support excessive loads without damage.

the only problem with that laptop is it is far more expensive than any computer I have ever bought, for work or for home. Otherwise it is a great idea...

Yes, such an ideal laptop would necessarily be a high-maintenance item. They do require a lot of upkeep. But I think that, in the long run, it would be money well spent.
At my age, I've given up the quest for the perfect laptop, and taken to the hobby of birdwatching. I'm currently seeking a red-headed, double-breasted mattress thrasher. Please let me know if you spot one, especially if it's unmated.

I've heard they inhabit this area, but I haven't seen any evidence. I promise, if I catch a picture in the wild, you'll be the first to know...

I have been given a task which requires my program to be able to monitor (in realtime) a person speaking. In particular, I need to know when he starts and stops talking.
The environment is that there is a dedicated microphone connected to a PC running WinXP and my "C" program (MSVC 6.0).
Being a software person, I do not have much experience working with speech and sound.
Any suggestions on how to do this?
All comments and suggestions will be appreciated.

I haven't done much of the same, though you might want to drop in on the audio section here at CP, or if you have a full weekend download an open source audio project and use the source to teach you how.
Try this project on fft for audio[^].
or visit several of the projects in the audio section[^] until you pick up the classes and knowledge you need.

I'm not sure much which way you want it.
I hope you want to monitor voice continuously.
if it is so , use the mcisendstring functions and API calls on windows to monitor the voice.

Dear Anonymous,
I don't understand what do you mean when you said which way you want it?
I understand that I will need to monitor the sound continuously, so that I can detect the starts and stops of the speaker.
Also, could you please expand on which mcisendstring functions and API calls I should examine because I need help and possibly don't know what questions to ask.
By the way, I have used the mci functions to play sound and record, but signal analysis is something new to me.

Lo all
like a lot of coder nerdies i'm pretty vacant when it comes to hardware.
Ive got a asus a7s8x-mx motherboard (running sempron 2800 CPU) which takes a 8x AGP card
the manual says its got to be a 1.5 Volt card and to only install a 1.5 volt card...
Can I get some suggestions for suitable 8x graphics cards which fit the 1.5 Volt requirements?

8x AGP cards are .8 volt. 4x AGP cards are 1.5 volt. 1x and 2x cards use 3.3 volt signaling. Recheck your specs, most 8x cards will run 4x as well but some motherboards that are 8x (.8v) will not run 4x mode.

k, heres the link to to the motherboard[^]
says "AGP 8X Technology
AGP8X (AGP 3.0) is the next generation VGA interface specification that enables enhanced graphics performance with high bandwidth speeds up to 2.12GB/s and twice as fast as AGP4X."
I looked at the sapphire 9600-xt and it seems nice...do you have a motherboard in mind you reckon would go well?

Bryce, I looked up the specs on the A7S8X-MS motherboard and most any 8x AGP card should work with it. The 9600 is a good price for performance card.

Too bad 2 9600 Pro were cooked in this board and 2 boards had their audio cooked twice by the cards. It really is an 8x AGP slot that requires a 1.5 volt card. The sticker over the AGP slot said so.

Beyond your compatibility requirement, what are your needs as far as graphics cards? There are a lot out there.
