i want to transmit video using 2.4 ghz rf transmitter with in a range of max 70m. i am searching for api to receive this transmitted stream using c#. plz mention if i could use the WiFi device provided with laptops for the receiving purpose? and does using a rf receiver and WiFi device with laptop will have different api's.

OK, great.
Zafar248 wrote: i am searching for api to receive this transmitted stream using c#
There isn't one built into the .NET Framework.

Only if your transmitter formats the video packets according to 802.11 Ethernet standards. There is no API to convert the WiFi transceiver into anything other than what it was intended for. You'd have to write you own drivers for the hardware to convert it's functionality into something that can understand what your transmitter is sending, which you cannot do in C#.
Zafar248 wrote: and does using a rf receiver and WiFi device with laptop will have different api's
The only API is what is exposed by the drivers for the hardware and that is only going to support 802.11 functionality.

I would concentrate on the hardware first...
Zafar248 wrote: plz mention if i could use the WiFi device
And they run at how many Hz? And they implement 802.11, which is a packet based transport and not streaming.
Anyway, 70m. Hmm, long ethernet cable I think and forget the rf. And the speed...

2.4 ghz, cant use cables, a university project.

And this bandwidth is available for public use?

I'd like to create a project that will work like a humerous alarm system in an office. Not overly because I don't want it to wear out but not lame either. My idea surrounds a monitor that runs on a linux box (ubunto). I want to attach a switch that when the monitor detects failures of any sorts we'd get a light and maybe some sounds as to catch attention (but fashinably). Currently the monitor exists on a server that has frequently update information to present in graphs, thru a browser (fire fox). But I am not limited to creating an entire mini application (hopefully) that sets off some hardware attached switch that turns on some neat humerous system. Any idea? or examples? Links?

They say that the ATI card is based on the 5870 which is a good card. I also know that drivers and a few tweeks to the hardware makes up a workstation card. Which card do you guys recommend based on your experience in mobile workstation? When I look at laptops most of them have the Nvidia option?

The ATI m7820 card is a much more powerful card than the Nvidia Quadro FX 2800m. HWINFO32 records 5 sensors on my m7820 alone. The ATI Firepro line has been a good success for ATI which is why for desktops there are several options of Firepros. The bad news is that the newer technologies it supports aren't used in most programs yet. I can think of only four programs off the top of my head in fact. The HP workstation driver was updated by AMD, and is now more compatible with a few programs it wasn't working with on my laptop. The new 3d modeling, video editing, and games are starting to support the firepro line. When I spoke to customer service on a 2d cell animation product... they basically said that they'd be testing on these technologies in 5 years. So.. maybe it's too new. Windows sleep/hibernate is a bit of a trick.. you'll have to figure that out. When it comes to modeling and video editing and games in programs that support these technologies... it's the fastest computer around.

Does anyone know how to disable that damn mouse wheel? So many programs use it for really annoying stuff (Like Corel X3 where if you bump the wheel it zooms the picture out so far that it is nothing but a dot). I don't want to use it for scrolling, zooming or anything. I just want to turn it off. Or do I have to rip it out with a pair of pliers to shut it down?

Interesting.
There is of course a "Mouse" control panel, but on my system (Vista) that doesn't seem to offer an on/off switch.
Google gives many hits, one points here[^] for "TweakUI"; sounds promising.

Not sure what Windows version you're using, but Microsoft says it's not possible to disable system wide in Vista. See http://www.microsoft.com/whdc/device/input/wheel.mspx[^] and grab the Wheel.docx file.

"Enhanced Wheel Support in Windows Vista"
Right. So they removed a way to disable, and called it an enhancement.

I don't think so. Apple is very careful about what hardware they include; but they do provide software support for available hardware.

Yes, take a 8 inch screw driver and prise the wheel out.

That makes sense.
There is a Mouse Control Panel, with a "Wheel" tab, so one should not need to change the registry; however the NumericUpDown there has its MinimumValue set to 1.

Ok,
I am extremely new to WMI. In fact, what I know about it is what I've learned in the past couple hours while trying to solve a hardware related problem.
What I would like to do is get a particular instance of a WMI class (Win32_NetworkAdapterConfiguration), cache the current settings on a users computer, change certain settings, run my operation, and then restore the original WMI class instance.
After reading up on the Win32_NetworkAdapterConfiguration from here[^], I have found that there are functions that can change the settings I am interested in modifying. My fear is, however, that since this application will be used on various systems with different hardware devices and original network settings that I will call a function that may have an unexpected consequences which I may not be able to restore (or know how to restore.)
So, my thought is that I'd much rather take a snapshot of the users network configurations, make my changes and do what I need to do and then do a complete restore of the user's original network adapter configuration.
Is this possible through WMI and, if so, is it advisable?
--
Sorry, I forgot to mention. I am implementing this within a C# application. I can interpret code in just about any language, but this needs to be a .Net solution.

A friend of mine plays World Of Warcraft far more than in good for him! He has a mouse (not the WoW one) that has a few extra function buttons and he asked me if it was possible to use them for some of the functions that the WoW one does.
My first reaction was yeah - listen for the messages from his mouse, block those but send new messages instead, so...
Do any of you gamers out there know what messages the WoW mouse sends (I've googled but not found anything so far) or if this is even possible?

Hi Dave,
Seems there are no gamers on-line. Either CP is an extremely serious site, or all gamers are very busy and can't be bothered.
Did you use SPY++ to look for any mouse messages? Maybe WoW interacts with the device driver directly, and no Windows messages are generated at all?

Hi Luc,
Without a WoW mouse to 'hack' then Spy++ isn't much use.
Luc Pattyn wrote: Maybe WoW interacts with the device driver directly
I think that is probably the case so unless I emulate the driver it can't be done. That's way too much work for a one off (would be worthwhile for a commercial product though - there are enough sad gits out there that would buy it!).
Thanks anyway

Spy++ is a good suggestion.
You may also want to check to see how the decide is registered. You may find that it is seen as both a pointing device and possibly a keyboard and is simply emulating keystrokes with the extra buttons.

That's the thing - I don't have an original to check so I was hoping that someone might have already done something similar and be able to share their reasearch.
Thanks for you time anyway
