I am going to suggest writing a c/c++ dl, anmd callilng it from c#.
For the functions themselves, look at the setupdixxxx() functions in MSDN.

Under Windows, you don't have any access direct to the video card, unless you go through DirectX.

Not my area of expertise. And from your description, you should be using C++ and the Windows Device Driver Development Kit. DirectX will NOT help you if your writing your own O/S.

Right!
I am using C++ but not Windows Device Driver Development Kit
Give me some suggestions :
1. Should i use that kit, i mean i have to port that driver into my defined enviroment.
2. Will the compiled code work without any hurdles of linking.
3. Wer from can i get that kit right now.
hope u will not get irritated by by questions.
bye

I don't think you can download the DDK without an MSDN subscription.
The point of the DDK is not to give you a development framework for your own drivers, but to show you how to write them. You'll have to write the drivers to the specifications not just of the hardware, but to your O/S's loader and device manager.

To the best of my knowledge i know bios calls to check the VESA conmpatibility of video card.
The returned modes include all resolutions actually supported by my video card but I only can get maximium of 256 colors.
Would u like to direct me to some URl or upload some code to get 1.6 million colors
hope to get some answer soon

An old PC is lying around here with a Nvidea GeForce 4 Ti4200 graphics card in it. Now i've got a newer PC with a Ati Radeon 9550. The question is: which one is better for gaming purposes (should i swap them)? The 9550 is a lot newer, but a lot cheaper too. The new system has a Athlon64 3200+ and 1024 Ram.
And would it be good if i bought a new videocard for 50 to 100 euro's, or won't that be much improvement?
Thank you

I know from experience that the 9550 is a DirectX 9.0 card, while the Ti4200 is only DX8.x. I upgraded from a Ti4800SE to a Radeon 9550 so I could try out Vista's Aero Glass interface, which isn't compatible with the GeForce 4 series.
In terms of performance, simply try the two cards on some benchmarks such as 3DMark2001[^]. I suggest that version because it only requires DX8.1, not 9.0.

I needed to develop a "volume control and Rcording control program" for my computer, but I don't know how to access the ports.
Can anyone tell me how to access the ports?
I am using the phone, mic/line pins of my sound card.
if required: windows xp 2006
creative sound card
love U much...

Why do you need to access the ports?
The multimedia API has provision for most of this stuff, and is more portable (works on more than one type/brand of card).

Thanks Steve, sorry for the delay
Well Steve, I thought a knowlege of port address was
important for controlling the volume of the signal that comes out of it. Because if I know the address that means I can buffer the signal data and process it with the software
that I am going to creat. Isn't that true?
I don't know much of this, I with my friend are working in college on this stuff.
love U much...

Let me see if I have this straight.
You have a sound card, and want to be able to record incoming sound from it, and/or play outgoings sounds.
If you are doing this under a Win32/64 system, then either the multimedia APIs or DirectX would be a good bet for this. In both cases, you can access the incoming or outgoing PCM data and do what you want with it.
If you are using some other system (DOS/L*n*x or similar/a.n.other) then yup, you probably need to know port addresses and such for the hardware, and it will be hardware-specific.

Steve, I realy appreciate your help. But may be I didn't make myself clear...
Let me say it in other words, there are some music softwares like soud forge, cubase sx, adobe audiotion ... etc that have a mixer inside, using these software one can can chage the test of the sound may be recorded as you said
either with the multimedia APIs or DirectX. Therfore I thought this would be possible to create a little software just like the "windows volume control form" to control the sound(volume, treble, basss)that comes from outside. So where does the data reside that comes from the sound port?
Thanks Steve!
love U much...

As Steve has said, the DirectX SDK will allow this.
It means that you work through standard interfaces to the card drivers.
Look up TAPI as well.

No, purchasing is slow.... while my project leader is itching to get my old system, only the CASE has been received!!
