There are two ways to accomplish this
1.Hooking IAT
you can patch the import address tables to your own functions, good for educational use only 
2.Hooking at kernel level
you will have to write a kernel level device driver, which will monitor all file movement, you will need DDK and a LOT of heart 
device drivers in 9x are .VXD files which are written differently than a .Sys(NT based device driver) so in order to support 9x system you will have to write a VXD file you will need 9x DDK for that and EVEN MORE HEART 
and starting with windows XP microsoft has added extra protection bit (also known as WP bit) to protect kernel level hooking (which suggest that they don't really like ppl hooking in to kernel)
hope it helped

yup...it does thanks. Well the app i am talking has nothing illegal about it so don't worry Could you point me to a decent article about IAT or maybe a snippet of code??it would be of gr8 help i read up Ivo Ivanovs API hooking revealed but it didn't have enough information on IAT .
thankx for the reply !

For displaying jpg images in ur app search CP for CPicture it's a nice class to display jpg in ur application
For registry support also try searching for CRegistry here.

I have to make a program like NotePad on Visiual Studio .NET 2003 using C++,but the problem i have is how to make Multiple UNDO.
Live isn't ForEver - LIVE IT

To make undoes, two steps:
1) define the scope about what's been done and to undo / redo. For example:
struct StepX
{
long PosFrom;
long PosTo;
ColorRef Col;
long Stroke;
};
2) use any of 'container' approach to store the steps. For example:
std::stack<StepX> or something similar.

Think about "commands"
for example, when typing text, you can make each character or word an "Insert Command", undoing this, will trigger another command, "Delete Text Command" and its undo command is the "Insert Text" ... you see the pattern ...
Each command must know the context and must be "self sufficiant" as much as possible, for example, "Insert Command" will have the text, and the position of insertion.
You need to implement a stack of commands ( written in the other answer ), on which you push and pop the commands.
From There, you can easilly implement the redo .

In some cases, multiple undo's are too complicated to make like the 2 previous messages said, expecially, when deleting part of some complex structure. If you're dealing with text, which doesnt grow enormously, you could also keep a copy in memory of previous operations. If you specify a, lets say, 10 maximum number of undo's and the text doesnt exceed 50k, that wouldnt be such a bad approach, although its pretty ugly
The method exposed before is much more neat and works for very large structure operations, but can also be difficult to implement.

There is more than way to do that. The easyest one I think is SetWindowText(). Search the MSDN for this function, you'll find the details.

I build a dialog application using VC++, and I want to deal with the keyboard message. but the ON_KeyDown fuction can't work, it can't be called by framework at all. then I find that I can deal with keyboard message in the PreTranslateMessage function, but it just like odd. I think it must have a better method.
thanks

KEYDOWN works with dialogs. You can try it with an epty dialog (no controls on it, not even OK and Cancel) and see the function gets called. But if you place any controls on the dialog the messege doesn't get sent to the dialog no more, it gets sent to a control on the dialog. That's why your function doesn't get called.
PreTranslateMessage works fine, I don't think it's odd. But if you find a better way please share .

There is a useful class named CBitmap,
DWORD CBitmap::SetBitmapBits(DWORD dwCount, const void* lpBits);
This member function should be helpfull

Send your answers to mikeza123@comcast.net
1. When a decryption section is added to a PE what is changed and must be restored for the program to function properly after dumping?
2. What exactly does it mean to dump a program?
3. What is an OEP and what should you look for when finding one?
4. What does IAT stand for and what is its member index in the Optional Header?
5. What API imports should you look for when looking for email sending functionality?
6. What ring must you be in to access debug registers?
lets see how smart yall are

1. Ha!, this is a trick question, you shouldn't actually dump a program, because it may contain sectors that won't get broken down over time, and that could cause a major environmental catastrophe.
2. That's when programmers of questionable quality hauls aged programs out in deep sea and throws them out to pollute the local environment.
3. An OEP is a little critter living in the forests south of Neverwinter, if you find one, you should look for its cave, because they are usually loaded with weapons and stuff...
4.I refuse to answer this question, because i despise everything IAT stands for...
5. The ones that are concerned about sending emails.
6. , now that's a dirty question, this should be in the soapbox.
So, how did I do?
