The computer did not have 570,000,000 bytes of contiguous RAM to offer.
Five birds are sitting on a fence.
Three of them decide to fly off.
How many are left?

You cant expect 570000000*sizeof(double) = 4.56x10^9 bytes = 4.2 GB from the heap.
If you really need that much memory (I doubt it! Revise your algorithms), you probably need to look into memory mapped files.
Who is 'General Failure'? And why is he reading my harddisk?!?

Nothing strange about it.
The most the memory manger can allocate for one buffer is around 1 gig not 4 gig. Look up virtual memory management in the MSDN library for more info..
You should be breaking up your storage requirments into multiple smaller buffer, how many and how small is up to you. You could use GlobalAlloc() to allocate the individual buffers, but now days the MSDN recommends using the heap allocation management routines instead.

I know that it can be a silly question but I would use a function to pass from text string "1234" to float 1234.
thanks in advance

atof or sscanf.
If you're using the Standard C++ Library, you could also use a stringstream and extract the data out using the >> operator.
Finally, you could consider Boost's lexical_cast[^] template.

use atof() function inside ur func.

Hi!
I have tried to clear a buffer, but it do not work.
I have tried clear().
Can someone help me

memset( buffer, 0, sizeof( buffer ) );
or, if using Windows.h, you can also use
ZeroMemory( buffer, sizeof( buffer ) );
although that's a macro which expands to memset in recent SDK releases.
The sizeof trick only works if your buffer was statically allocated as an array (so that the compiler knows the size). Otherwise, you'll need to record the size when you allocate so you know how many bytes to zero.

Hi
I use PKZIP(R) Version 2.50 for zipping some files.
I use this to make a file with all DBF, SDF, MDF files in it
PKZIP -add -nozipextension -span -pass=mypass "N:\TEST\TEST.HI" *.DBF *.SDF *.MDF
I implemented this in C coding too, works great when you want to write to the local drive. To the network share like 'N' is .. it doesn't work.
It gives me this error:
Encryping files
Creating. zip: N:/TEST/TEST.HI
PKZIP: <e7> Can't create: PKBACK# 001
Anyone got any ideas? Was this a bug that got fixed by the latest release?
Best regards
Anoy

I was forgotten something to mention:
I have all permittions on the sharedirectory.
I can place a file, delete it, append it etc.

i have no more ideas, i lodge! Here's what i want to do:
Every time the kernel32.dll is loaded, it should load a arbitrary dll, which then should create a log file to capture the name and the process id of the process which has loaded the kernel32.dll (and so the injected dll).
Here's a brief summary of what my code does:
It searches for the section which can be executed, copies my code to the end of this section and changes the entry point in order to jump to my code, and after my code has been executed (and the dll has been loaded - which only should happen if the dllmain retrieves DLL_PROCESS_DETACH) it jumps back to the original entry point (which has been saved before).
The difference between a normal dll and the kernel32.dll is the calculation of the address of the LoadLibraryA function!
I have tried this whole thing with Windows 98, and if someone now says that i am crazy and the stuff mentioned before won't work, even not if a miracle happens, i can say you are wrong. Windows 98 executes my infected kernel32.dll like it does with the original one, without a sinlge error. And YES, my code is executed too, BUT and that's my problem, the injected code doesn't load the DLL, and I DON'T KNOW WHY!!!!!!!!!!!!
Can someone help me ?
Thanks in advance!

Yes, i did!
But my problem is that the LoadLibraryA function doesn't load the dll!!

I've been using VS.NET 2003 for over 6 months now without any problems. Over the last few days I've noticed that the output window is refusing to stay undocked between sessions. It doesn't matter what solution I load the output window always defaults to being docked when VS.NET loads. It will stay undocked for the duration of the session. Does anybody have any suggestions what might be causing the problem or know where the setting is stored?

I've managed to rectify the problem by using the 'reset window layout' button from the options dialog.

Hi All,
How to write a antivirus program in vc++..
Regards,
A.Ilamparithi
|
|

|
|
First find some virus, study how they function, and how they infect the system, Then figure out how to reverse its action, And there you have an antivirus.

Wow - that's a tall order. I would suggest that you actually need to actually design and write one, and then ask for help on more specific issues.
But for starters, I would guess you need to find out how to:
* Hook the filesystem (so you know when files are being changed)
* Storage and update mechanisms for virus signatures
* Heuristics to detect new viruses
* Efficiently scan the changes to see if they match known virus signatures
* Isolate infected files and/or revert the changes being made (for isolation, you probably want a storage environment where files cannot be directly accessed or executed, like an encrypted virtual file system?)
* Internally validate your code to ensures it isn't infected by malicious code or otherwise affected by somethign trying to undermine it (man-in-the-middle attacks, shutting down components, outright replacing them, etc)
That's a big job, so I wish you good luck.

OK look at one I wrote and see if this would help you.
If so I can post the source.

Please remember I just check for one virus at a time at this point.
To do it properly you are going to have to do some array work.
Also may have a leak or two.
Wrote it in one night for a buddy the got WelchWorm.
Used a great deal of code off this site.
Best Wishes,

I want to get the driver as listed in title .But I can't do it with GetDriverType because it's parameter can only indicate the cd-rom.And with
GetVolumeInformation I can't get more useful infomation.please give me some suggestion.
thank you!

When I call UpdateData(TRUE) on my non-modal dialog, a box pops up saying that this action is not supported.
Is UpdataData() strictly for modal dialogs?
I have several textfields linked to some UINT variables.
