Hi Zoltan,
> There is a KB article on this here[^], that may be of value.
It reports 500 per process for NT 4. Seems to be the same for XP.
> Also there are some obscure registry settings
Those report 10000 handles. Weird. When Googling for an answer, [RedHat] Linux reports 1000 simultaneously opened files as maximum.
Fortunately 'decently' recoding the previous mess the solved my agony.
Thanks,

Yeah but for handles you must count a lot of things like synchronization/event handles, registry key handles, thread handles, ui object handles (pens, brushes, etc) and file handles.

You can modify the maximum number of file handles opened simultaneously. I believe the ceiling is 2048 file handles. You can use _getmaxstdio[^] to verify this on your operating system. If you wish to modify this value you can use _setmaxstdio[^] to set the new value.

The functions _get and _setmnaxstdio are 2005 and 2008 specific. The project was compiled with the old VC 6.0.

Correct, when using the number 2049 in VS 2005, it reports an error.

This is not correct, what gives you this idea? This function is part of the standard C runtime library. Those functions have been around for as long as I can remember. Possibly even MSVC 5.0 I will have to check later.
I also still use MSVC 6.0 for some projects... I just checked and it works just fine. The declaration is inside stdio.h on line 340.
It exists in the VC6 documentation as well.

1) The link in the previous reply referred to a webpage in which explicitly "VS 2005 and later" was mentioned.
2) When typing _getmaxstdio in the VC 6 help, a messagebox "No topics found" pops up.

And you are absolutely right. I compiled a simple snippet with both (get/set) under VC 6, and it ran flawlesly.
Thanks for the additional info.

I'm not sure if your old enough to remember this but in the old MS-DOS days this was achieved by editing a file called CONFIG.SYS in which you could add:
FILES=255
http://www.easydos.com/files.html[^]
Since Win95 and Win98 was built on top of MS-DOS you could still modify the value in those operating systems as well. If I am not mistaken I believe the default value in Win95 was 60 handles which was set by IO.SYS in the root boot directory unless overridden in CONFIG.SYS.
Ahhh the dinosaur age... now I'm feeling old.

Yes, i do remember, i'm that old that i've been working with punched paper tape and punched cards. Devising a diode array to translate EBCDIC into ASCII.
When running into this limited amount of files, CONFIG.SYS was the first file to look for. Under XP it is 0 bytes, not too much space to hold any info of particular value.
Randor wrote: If I am not mistaken I believe the default value in Win95 was 60 handles which was set by IO.SYS in the root boot directory unless overridden in CONFIG.SYS.
Under DOS (3.2) it was usually set to FILES=20. The default of 8. "Those were the days", compiling programs into .COM files of 512 bytes or less.

Hi Guys,
I have a major problem right now. I have a Kerio Mail Server which is currently installed in windows xp home edition. And the number of email accounts are in this Mail Server are only 50 users.
A week ago all our incoming and outgoing emails works fine, and there are no delays of mail delivery. And just this week starting on Monday, we only received incoming emails. And our outgoing emails will be delivered late.
When we send emails to yahoo.com, gmail.com, etc. the message will be delivered 6 hours to 1 day. And I haven't change anything on the configuration. What do you think really is the problem? It's a week now and still it doesn't work properly. The problem is with our outgoing emails.
Was it our Static I.P. that was being blocked because of greylisting?
How can I correct this problem?
Thanks Guys

Holla,
could be greylisting. 6 hours to one day sounds like a standard SMTP retry period, so the first attempt is declined, the second one is allowed. This, however, is not your responsibility.
Cheers,
Sebastian

Hi all,
I intend to filter IPv6 packets.
I have already succeeded in capturing and decoding the packets n a human readable format.
Now i want to block some unwanted IPv6 traffic
say:
I do Win XP to drop packets with destination address A and port A1 and source address B and port B1
how can I do this?
will manipulating the IPv6 routing tables on my machine work?
I did
C:> netsh
netsh> interface ipv6
interface ipv6> show routes
this showed me some routes for IPv6 traffic going out of my machine,can i manipulate them to block certain traffic.
Is there any other way of doing it?
please help
thanks and regards

One specific user or all users? You can use any autorun facility. Registry, Startup-Folder, whatever you want.

I'm writing a custom PE loader, and I finished everything except relocations, which I can't find anywhere in the EXE. I'm using Windows's notepad.exe as my initial test. Both the BASERELOC directory entry (DataDirectory[5]) and the PointerToRelocations field of the .text section are set to all 0's. Also, there is no ".reloc" section. Any ideas where these relocations would be located?

Hi zildjohn01,
The image may be bound. I know binding overwrites the IMAGE_THUNK_DATA entires of the IAT. But I also believe that an image which cannot load at it's preferred address (after binding) will fail to load.

Since the EXE is the first thing to load into the process, and therefore there are very few allocations (a few DLLs are pre-mapped, such as kernel32.dll), it very rarely needs relocating. You might do it if you wanted to load an EXE as a DLL in another process, but more commonly you just want the resources out of it, in which case you specify LOAD_LIBRARY_AS_DATAFILE.
Because relocation is so very rarely unnecessary, the linker provides an option, /FIXED, to control generation of relocation information. Since at least VC6, the default for EXEs has been to set /FIXED and not generate relocations, and for DLLs, to set /FIXED:NO (which does generate relocations).
It's not that you can't find them, it's that they aren't there.
The relocations information in each section is really for the use of the linker to link .obj files into an .exe or .dll. In a finished DLL, only the Base Relocations (.reloc section) are present.
.NET executables have a .reloc section containing one relocation, which is a pointer to the start of the Import Address Table. When the loader loads the DLL or EXE, it overwrites this entry with the address of the function imported - for an executable, _CorExeMain in mscoree.dll. The two bytes before the address that is updated are 0xFF 0x25, which are an indirect JMP instruction. The 'entry point' field in the IMAGE_OPTIONAL_HEADER structure points to the start of this instruction, so on loading the program, Windows calls this address which immediately transfers control to _CorExeMain. DLLs are similar but use _CorDllMain. In this way, a version of Windows which knows nothing about .NET can still load a .NET program as if it were any other kind of program with very little x86 code included. I'm guessing it's compiled at this odd location - after the Import Name Table - so it's on a page that will get discarded very quickly, as this instruction will run exactly once.
I believe newer versions of the OS understand .NET programs and just invoke mscoree.dll directly, not even bothering to map this page. The 64-bit versions would have to, if they're going to create a 64-bit process (particularly on Itanium where 0xFF 0x25 means something else entirely - actually you'd get an alignment fault straightaway as that processor requires instructions to be aligned on 128-bit boundaries). If you specify /platform:itanium or /platform:x64, the C# 2.0 compiler generates a PE32+ structure, no import tables, and puts 0 in the 'entry point' field, so the 64-bit OS must understand .NET binaries directly.

Awesome thanks, you guys are both right, they were resolved during linking.
My options now are to either create a separate process, or manually parse the assembly code (ugh). We'll see how this goes.

I'm still battling to diagnose the error below when I try and start VS 2008 as a non-admin user. This error started after an ugly shut-down of my Vista Business desktop machine. On Friday it worked, and on Monday it didn't.
I have been able to gather that this error is not unique to VS 2008, and I have performed a repair of VS that made no difference. I have also run as admin and disabled all add-ins. I believe this is a Windows registry issue, and not a VS issue. Please could somebody recommend a good registry repair tool?
Error log:
Faulting application devenv.exe, version 9.0.21022.8, time stamp 0x47317b3d, faulting module ntdll.dll, version 6.0.6000.16386, time stamp 0x4549bdc9, exception code 0xc0000374, fault offset 0x000af1c9, process id 0x1630, application start time 0x01c889a70153ad96.

Hi, my problem is with a corrupted WinXP OS (Media Center Ed.) on a HP desktop (circa 2005).
The PC in question belongs to my 15yr old nephew ...yadda yadda yadda... it problably was subjected to a virus.
The problem was the PC could no longer start. After going through a "system recovery" mode using the F10 key, I was able to get past some problems with some apps (missing/corrupt .DLLs, etc.) and to a point where I could use the machine to copy files to CD/DVD for backup.
I tried the HP system restore and it had two methods - restore or destructive restore (basically a FORMAT). The basic restore still gave some problems down the road. It still seemed to be unstable.
Symptoms:
1) unable to run XP's System Restore - only lists two dates for restore (the day it totally crashed and the next day when I tried to recover using system applications.)
2) windows starts only in Administrator mode. There used to be option of listing available users to Login.
Questions:
A) since i can burn to DVD, which files do you recommend I save - in case need to format.
B) shouldn't I see more available Restore Points? I believe that System Restore was in ON state prior to problems.
C) I don't have NET access on this PC as it was removed/restored to basic settings. Best recommendations for getting drivers, OS files?
D) If I have to FORMAT, I want to rid this HP machine of all the junk that (HP loaded and) makes my machine run slowly. Suggestions?
Thanks for the help and advice (beyond my questions?) that you offer.

A) documents and settings (should cover most of his files) and any directory he identifies as being used to store files. Also check the Program Files subdirectories, because some clever software stores its data inside the Application Directory, not the User Directory.
B) Sorry, no experience - I always disable it and backup manually.
C) Basic functionality should be available by using the installation media delivered with the computer. For updated drivers: A ***PHYSICALLY WRITE PROTECTED*** USB-Stick should do nicely. You never know what kind of malware he caught, better to avoid all risks. If you cannot get a stick with a write-protection switch, use a USB-card reader with a SD-Card. They usually all have write protection switches and the speed should be similar.
D) I don't know about HP, but Toshiba and Sony provide a two-stage-recovery, meaning that you get a clean windows after using the recovery CD and a "urgent request" to install the rest from a seperate Application CD. Just skip the App CD and you should get a clean Windows.
If the basic recovery includes the software provided by HP, deinstall it and then run some registry cleaner to remove the last traces. You could also delete the folders that are not necessary for a standard windows installation, then run the reg cleaner again...
Cheers,
Sebastian

A) Save documents and settings and any other directory you care of, but be aware if it's virused you may care the virus/malware to the new system.
C) If you do have the HP provided OS cd it should contains all the drivers incorporated in.
After Windows is installed it will take care and install all drivers. At least that how it works with mine.
