Hi All,
Can anyone tell me the registry entries that will be used by Windows XP to store any wireless connection that I add? I could figure out these registry entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WZCSVC
HKEY_CURRENT_USER\SOFTWARE\Microsoft\EAPOL
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EAPOL
But I guess there are more entries, which I am not aware...
Thank you,
AJ

Didnt the Java virtual machine get pulled from XP because of the US courts rulling on Microsofts mis-use of Java?
I seem to recall there is a 'developement' usage JVM knocking around though that can be installed.

Yes, I want to access the internet from this device.

If its data only you need then you can use these devieces at www.option.com. They work on GSM networks. If you have CDMA, the US network, then you can use a Sierra card.
Option sell their cards through channels, so you will also see them in the shops badged as Vodafone or TMobile cards for example.

Hi, I have purchase a VGA card serveral year ago. This card is Trident MicroSystem 9750. At the time that I purchase the driver is available only for windows 9x and NT4. Now I need to upgrade my system to windows server 2003. But the operating system do not detect this card. I try to check over the internet but I didn't find any website that allow me to download an update driver for this product. Does anyone know a place for me to downloads the driver for this card for windows server 2003? Thank in advance

Sorry, I think you're going to have to replace this card. It doesn't look like they made any drivers for Windows 2000 or later, and I don't think NT 4.0 drivers were compatible.
In a server I'd go for something cheap and server-oriented. You'd prefer a reliable driver over performance. Our servers have an ATI ES1000 chip, but that's integrated on the motherboard. The cheapest card I can see that would probably suit you is a 64MB Radeon 7000-based card from Sapphire Technologies that costs £17.60, but you have to use ATI's standard unified drivers, possibly including their .NET-based Catalyst Control Centre which is an utter waste of space.

Hi,
I am trying to track something down in the TEB I figure If I do a GetThreadContext
The FS Segment register points to it
However like all segment registers it comes back as 16 bit value specfically in my case 0x0038
anyway to convert this to the 32 bit selector value
Thsnkx

|
|
|
|
The 16-bit selector value in the register is an index into the global or local descriptor table. Bits 0 and 1 (the lowest two bits) are the Requested Privilege Level; here it's 0. Bit 2 indicates which table to look in, here it's set to 0 meaning the Global Descriptor Table. The remaining 13 bits are the index - the index is multiplied by 8 and added to the base address of the table (the GDTR or LDTR register as appropriate).
The segment descriptor itself then lists the base address of the segment, i.e. the address that segment-relative addresses are relative to.
Windows only uses the FS register. All other segment selectors point to descriptors of the appropriate type whose base is 0 and limit 0xFFFFFFFF, that is, they address the entire contents of memory and addresses are absolute.
x64 effectively disables all segment registers apart from FS and GS. Even then only the base addresses are used; the limits are no longer checked.
You shouldn't rely on anything in the TEB in your code. Use supported structures only (e.g. TlsAlloc for allocating Thread Local Storage, __try/__catch for manipulating exception handlers, CoGetContextToken for COM+ context). If you want to examine the TEB in a debugger, use WinDbg or another debugger from the Debugging Tools for Windows[^] kit and use the !teb command.

SuspendThread(hThread);
c.ContextFlags = CONTEXT_FULL | CONTEXT_CONTROL;
GetThreadContext(hThread,&c);
GetThreadSelectorEntry(hThread,c.SegFs,(PLDT_ENTRY)&SelEntry);
teb_ptr = ( SelEntry.HighWord.Bits.BaseHi << 24) |
(SelEntry.HighWord.Bits.BaseMid << 16) |
SelEntry.BaseLow; // Fs pointst to TEB
my_ptr = (char *)teb_ptr;
my_ptr = my_ptr + 0x2c; // point to ThreadArray sotrage
my_ptr1 = *my_ptr; // point to first slot
Mike
Think you are right my_ptr1 points to the first threadocalArray
and it 0 Hmmmmmmm ????.

I'm using winmm.dll to play wmv video. I wanted to find out wmv video Frame Rate and Video Length of any user selected video. I'm wondering what is the API call in winmm will return those values? or any other way to find out?
For avi files (avifil32.dll), AVIFileGetStream will return stream, so stream.CountFrames and stream.FrameRate will return those values.
Thank you in advance.

I had this incredible idea and i dun know how to implemnt it.
I want to create an external graphics card(i have no idea how to make 1) attached via USB port which can run games(not the current released versions but games made for this graphics card) ppl with sh*tty graphics card would not have to waste money on new cards. Although they will not be able to play new games made to run on Nvidia/Ati graphics card.
The biggest problem i'm facing now is how to display all these 3d calculations of images or models onto the desktop.

There're USB gfx adapters out there currently. The problem is that USB bandwidth is so low they're limited to IIRC 1024x768x16x60hz and still stutter anytime the USB bus is being hit hard by anything else or the CPU is busy doing something else. Firewire800 might have enough bandwidth to make a semi decent gfx adapter but you'd only be able to sell it to the 3 people who have firewire800 ports. USB3 with it's gigabit optical connection might work (if it doesn't strangle the host CPU) but is several years away.

wow ur knowledge about this stuff amazes me. I want to create a device like PSP with my own graphics i have no idea where to get the components. I know it uses the MIPS microprocessor with ATi/nivida GPU(not sure which one).
Is it possible for an individual to make their own GPU card.

|

actually, I just looked at a few reviews of USB gfx adaptors recently hoping I could add a 3rd display to my laptop.
You're on your own with the PSP type device.

I never even considered looking for such a thing, for second display for my laptop. Its own display is broken, and it costs half the price of a new one to repair, plus ten days minimum downtime. I won't be buying another one for a few months yet, so a USB gfx adapter could be an option.

unfortunately they (and thier slightly better performing PC card brethren) have rotten performance and cost a few hundred bucks.

I have a working app I wrote that uses software breakpoints but read a great article on using hardware breakpoints, advantages - non intrusive and speed. Since both aspects were appealing I undertook a conversion. I began porting the dll I had written to asm and implemented the proper routines. However, I am having some very strange problems that have taken me hours to try and figure out and I'm stumped.
Here's the shorthanded basics...
#define MB MessageBox etc etc
while TRUE
{
ContextFlags = CONTEXT_DEBUG_REGISTERS
GetThreadConext
Dr0 = Addey1
Dr1 = Addey 2
Dr7 = 00000000000000000010001100001111b
SetThreadContext
WaitForDebugEvent
if ( dwDebugEventCode == EXIT_PROCESS_DEBUG_EVENT )
{
MB __T("Process exiting")
break
}
if ( dwDebugEventCode == EXCEPTION_DEBUG_EVENT )
{
if ( ExceptionCode == EXCEPTION_BREAKPOINT )
{
if ( ExceptionAddress == Addey1 )
MB __T("Hello from addey 1")
elseif ExceptionAddress == Addey2 )
MB __T("Hello from addey 2")
// here we clear the Dr regs enable single step in FLAGS, back up EIP
// continue & wait for debug event and then xor FLAGS and continue
// pretty much the same as the working dll that uses 0CCh breaks
}
else
{
ContinueDebugEvent - DBG_CONTINUE
continue
}
} // end EXCEPTION_DEBUG_EVENT
ContinueDebugEvent - DBG_EXCEPTION_NOT_HANDLED
} // end while
Now - the results are. If the app is ran the MB saying "Process exiting" pops up. Load it up in Ollydbg and run it, same result. If I set a breakpoint in Olly at the if EXCEPTION_BREAKPOINT, it hits and single stepping in results in trace into kernel32 which then traces into ntdll which returns back to the app and the proper MB "Hello from Addey x" msg as it is designed to do.
What gives? I have thought possibly that Olly is making a Ring0 call therefore can properly handle the DR reg calculations, but that would mean I would have to create a wdm or sys file runnning in Ring0 just to look at hardware breakpoints? Creating a Callgate to ring0 or manipulate SEH isn't feasible as MS could break such code with a patch, not to mention it's just not reliable from machine to machine.
I really do need the speed of the hardware breakpoint as the current dll is fast but not as fast as is desired, not to mention ReadProc and WriteProc 0cch is costly. I would be prepared to write a device driver but it has to also communicate with Ring3 code i reckon using MemMapping would be best but I'm a newb at the current device driver implementations.
Any help on why this code runs when traced in a debugger using single stepping but just exits when run would be most appreciated.

Wow, no answer on this yet?
Ok the 2 addresses are the program's send and receive addresses. I listen for the incoming/outgoing packet and read a byte sig and filter that by packet type. I send the data from the packet to another window alerting the user of an event in the case they may be semi-afk or in another window if it's the byte sig we want i.e. "Global announcement: there will be a server reboot in 1 hour!". It's been very useful but I want to speed it up by using hardware breakpoints which I also read is recommended over software operation.
I reworked the code and it is ok on recv but on send the program closes immediately. I have read and read and googled and googled and still cannot find a clear answer. Do I have to be in Ring 0 to manipulate the Dx regs and set them for the remote thread, or can this be done in userland?
