Hi fat_boy,
thanks for your comment.
Manifest is already part of the app and the dll. Additionally we've signed the app, dll and sys, but it does not help.

So it works on XP as a non administrator but on Vista doesnt? (ie, it needs admin rights to work).
This should be the same, the issue on Vista is whether the exe will auto prompt for permission (thats what the manifest file does).
Have you checked the local security policy on the machines? Also, depending on how you are accessing the filter driver, you can accept a lower security level. If its via IOCTLs you can down grade the security needed so a non admin can access it. (You then use MAXIMUM_ALLOWED in the call to CreateFile() )

Yes on XP it works, but Vista needs to elevate (run as 'admin') with UAC enabled.
Mhmm, local security is a point, but not practicable (...sorry), since most of our users won't dig around (or even worse: do not have the knowledge) in the security settings. We have to deal with a default Vista installation and there the UAC is enabled for sure, while security settings are strong...
We thought about having a second driver, which does the IO control between the app and the filter driver, but are not sure if this will work. 
At the moment we're stuck  ...

OK, so is the issue:
1) The app, when run, doesnt elevate, and thus cant access the driver.
or
2) The app, when run, does elevate, but then cant acces the driver?

The issue is 1). We do not want to elevate our application, in order to avoid the popup dialog of the UAC. The app should run without any annoying dialogs, the way it runs on XP. E.g. Wireshark also accesses a filter driver, but without any elevation... and we do not know how...
|
|
|
|
|
OK, so you want without a popup. Two questions:
1) Are you accessing the filter driver through IOCTLs?
2) Does your CreateFile() specify MAXIMUM_ALOWED?

|
|
|
|
|
1) Yes we need IOCTLs
2) Actually this is GENERIC_READ|GENERIC_WRITE
CreateFile works, but the DeviceIOControl returns 87.
|
|
|
|
|
1) How are the IOCTLS declared? Can you paste in an example of one?
2) Make this MAXIMUM_ALOWED. If you can have GENERIC_READ|GENERIC_WRITE it will be given to you. If you are only alowed WRITE that will be given to you. So using this macro means you will always het the highest rights you can get which means you have the highest chance of your code succeeding.

 Jep!!!! MAXIMUM_ALLOWED did the trick!
Driver works now without any UAC issues!
Thank you!

Yeah, its a good trick to always use this value, you always get whatever the system can give you, and in combination with setting the security on the IOCTLs very low you could even get this working under a user profile.

I recently upgraded my PC. but I have the Hard disc with old IDE type. i have made it as slave and put my DVD drive as master. when I access my DVD drive ,my HDD performance is getting affected. can any one suggest some idea to rectify it...

Make the HDD master. Then in concurrent usage scenarios that DVD will be the one slowed by having to wait to send/receive data. Alternately put the drives on separate channels.
As long as they're sharing a ribbon, one will be the loser anytime you're trying to use both at once.

I designed a filter driver which is located in device stack between "bus driver" and "function driver". The filter driver has a "symbolic link".
Assuming there is two win32 applicaiton named "App-1" and "App-2". "App-1" is communicating filter driver through symbolic link. On the other side the aim of the "App-2" is going to prevent/permit communicaiton between "App-1" and "symbolic link".
Is there a method to prevent/permit DeviceoIoControl(...) for "symbolic link"? OR prevent an applicaiton to communicate with symbolic links.
Thanks for your help.
(Platform is WinXP)

Yes, put another filter on your symbolic link and disable devioctl.

Hi all!
I'm not sure if this is the best place to ask, but here goes.
I was wondering if it was possible to change the BIOS Font Color (EG: RAM Count) away from white, to an alternate color (Say Red?) in Windows XP?
I have searched Google, yet found nothing.
Thank you for your time!

Nope. Windows XP has nothing to do with it since Windows isn't running when the BIOS screens are visible.
You'd have to know exactly where the color number is stored in the BIOS Flash code, change the value, then reflash your system BIOS with the updated code.
You, more than likely, will not find any information on the web on how to do this since noone to very, very few people ever does attempts it, let alone succeeds at it.

Hi. I was wondering if anyone has done work on controlling where a webcam looks (its viewpoint)?
I am interested in controlling webcams that have full range of view (360-degree, 0..90 degree above horizon).
I only started researching the Logitech line (QuickCam Orbit AF). Other products out there?
Software Development Kits (SDKs)?
Thanks,
John John

Isn't this only a half FOV? You'd need a minimum elevation of -90* to get the other half.

Watching free online movies are becoming popular day by day as a means of cost effective entertainment but finding a legal site that can assure of its legality is really a difficult task for us.The reason is that there are several illegal and pirated online movies site available on the internet that are giving huge promises of thier program but they end up being a scam.
However, the legal way to watch free online movies on the internet is to get a lifetime membership from secured movies download site.You just have to pay the one time membership fees to get instant access to watch your favourite online movies,Tv shows, music, games,software and much more.Please do not run over the free movies download sites that are claiming to give you access to watch free online movies at no cost.But the truth is that they do not have a legal software and there are many cases of copyright infrigment.They cannot provide a good quality and are made only with the intentions to hack your personal information and leave your computer with viruses.
Now I am going to tell you some tips that you must see in an online movies download site so that you did not face any scam on the internet.
1. Check out that the website is providing guarantee.The online movies download site that does not provide a guarantee are not confident in their program,so be very cautious.The guarantee is made that if you do not like the program then you can take your money back.So always look that the website is providing guarantee.
2. Always check the company pay processor.The program that uses third party pay processor(paypal) does not scam you because the company has to follow srtict guidelines as set by their pay processor.If they do not follow pay processor guidelines then they can face suspension or even cancellation of their accounts.So, always check the company pay processor.
So,the program that offers a guarantee and also uses a third party pay processor such as paypal are the two keys to assure you that you will not get scammed by them.
If you are looking for few good options that meet the criteria that I have mentioned, I will personally suggest you a few companies that you should look for.These companies offers great training program along with 100% guarantee.You can at least try them out and you do not need to worry of getting scammed as per my definition. When you pay for something and loose your money that you have initially invested is called as a proper definition of scam. If you are able to try something and get your money back if you do not like it is actually a good business.
