I set the display to large fonts and it still says 96 dpi.
>it *should* come back with the same mm size that was reported with normal fonts
It does, but the reported size is wrong.

On windows versions prior to vista DPI scaling was so fubar that if hardware didn't lie and claim 96 DPI everything was a mess. Vista's better, but anytime it has to scale an app bitmap image instead of a vector image it still sucks.

Hi all,
do value of index of the ethernet cards and also wireless adapters  in pc have any definite range?
|
|
|
|
|
Indeex range?? What are you talking about?? Where are you looking that shows you an Index?
|
|
|
|
|
Each network adapter has an ip address,subnet mask attached with it,right?Similarly,an network adapter also has an index associated with it,through which we can bind a scoket to it.the ethernet adapter that i have has index 2.so,i am asking whether there is some range for index of an network adapter?
|
|
|
|
|
OK. The range you're talking about is technically 0 to Int32.Max. Though, system resources limits that to probably a few thousand adapters.

I didn't get your answer.see i have to develope an application in which i have to distinguish out of the network adapter cards available in the system,which one is ethernet and which one is wireless.Its easy to know which one is ethernet but for wireless i am not getting anything.But one think that I have noticed is index number for ethernet is genearlly 2,3etc and for wireless its 65530 etc.I was thinking to distinguish both referring to the index number.I hope u now understand what my problem is.Pls help if u have any answer to it.Thanks...

That's the wrong way to go about it. You have to query each adapter to get it's type.
You don't say what you're using to get the adapters list. I'll suggest using WMI to make it real easy to tell the difference. Check out the Win32_NetworkAdapter[^] class.
|
|
|
|

I have used GetAdapterAddress and GetAdapterInfo which are part of win32 API to get list of interfaces.But the problem is that for ethernet everything is showing fine.But for wireless adapter the type it is returning is "ethernet".But it is returning all other information correctly about the wireless adapter such as ipaddress,index and name.I don't know why its happening.and I can't use WMI.
|
|
|
|
|
OK. Look at Interfaces, not Adapters. You can get the media type (IEEE802.11 - Radio Spread Spectrum) from the Interfaces table. Check into the GetIf* functions instead.
|
|
|
|
|
I didn't get you.Could you please give me some links or some source code so as to understand what you have specified.Thanks....
|
|
|
|
|
GetIfTable[^]
If you look at the left side, you'll see all the GetIf* functions.
|
|
|
|
|
Thanks for your help but It didn't help either.The function displays type of wireless as ethernet.If you know any other method pls do reply.
|
|
|
|
|
Yes, it does tell you. That's the only method besides WMI to get what you want. The Type should have come back as IEEE802.11. If it didn't, then it's the fault of the driver for your adapter. dwType can currently come back with 144 different interface types.
|
|
|
|
|
no the type came as "ethernet".In Linux also the type for wireless adapter comes as "ethernet" when you give ifconfig.U can try it also.
|
|
|
|
|
I don't care, because I use WMI to do this stuff and it's not lying to me.
I already told you that this is the ONLY way to get the data you want, save for using WMI, which you "can't use". There is no other option. If it lies to you, there's nothing you can do about it. Well, other than see if the manufacturer of your wireless adapter has updated drivers, because that's where this data is coming from.

mine is not a built-in adapter.its a USB adapter.Can that be a reason for it?
|
|
|
|
|
I have no idea. I'm not going to repeat the bottom line for a third time.

I have swapped out a dvd drive on an old pc, and the message is coming up that that the system has loaded the drivers but is unable to locate the drive.
Any suggestions?

Assuming the DVDROM worked in old pc, and did not have its own "special" drivers,
Try ...
Uninstall DVDROM from Device Manager, reboot and let windows find it again.
Motherboard BIOS set OK ?
DVDROM Jumpers set properly ?
IDE Cable round right way and NOT damaged ?
Power Supply cable - pins in plug not bent or poorly fitting ?
Can you try another DVDROM/CDROM and get same results ?

Got it working now!
Did the uninstall/reboot, no joy.
Didn't touch the BIOS, as settings looked ok.
Jumper was set right.
Tried reversing the cable, no joy.
Power ok.
Couldn't try the other DVD drive as that was the broken ome I was replacing! 
Then, enlightenment!
Off to the registry... delete the thresholds!
reboot and voila!

I want to write such a driver for my cdrom:
1) When a specified disc(a encryped disc with some special information which can indicate that disc) injected in it and the user application want to read the disc, my driver will decrypt the content of the disc and return the decrypted content to the user application. Otherwise, my driver will transmit the io request to the default driver in the system.
How to implement such a driver?
2)Further more, if i want the user keep my specified application running to use the driver, in another word, only keep my appliction running can make the driver decrypted my disc or the io request would transmit to the default driver, should i have to create a exclusive mutex object in my user mode application so that my driver can chose the right action?
****edited******
I know, i should add this driver to the default driver which is present by the os. I found a driver implemented this. But it was surprising that, the driver simply called the IofCallDriver to deal most of the io request, only implemented IRP_MJ_POWER,IRP_MJ_DEVICE_CONTROL,IRP_MJ_INTERNAL_DEVICE_CONTROL, and IRP_MJ_PNP. But how it deal with what i want? Since it didn't do some its own task in IRP_MJ_READ, how did it hold the data readed from the disc?
Regards

Hi Dears
I want a code to find and get HDD Serial Number without WMI in Windows XP with Framework 2 _ VS2005
Can anyone help me?

Cute. You posted the exact same question in an article that shows you how to do it. Read the article and loko at the code same provided at the top and you'll have your answer.
BTW - spamming the entire site with the same question numerous times is considered very rude.

Hi All,
Iam faced with this problem.
1. I have an application that should be capable of handling two usb mice. Let me elaborate.Two usb mice (or mice
like devices) will be connected to my system (windows xp) obviously through USB ports. I should be able to assign
or say that the mouse connected to this (one fixed) physical USB port is my left mouse and the mouse connected to
another (fixed one) USB port is my right mouse. Next, I should be able to distinguish between the events generated
by both the mice.
2. I have tried Raw Input Api whereby Iam able to distinguish between mice inputs. But Iam not able to fix my mice as
left and right. I tried to distinguish the mice using usb port ids. But whenever I plug out and reinsert my mouse,
the port id keeps changing (is this observation correct?). Also, for this requirement, I should be able to say
before hand what is the port number of my left mouse and my right mouse.
Any help on this would be highly appreciated.
