hi all i want to know that how to capture the data passed through the network and modify its contents,suppose i had client and server and they communicate each other through sockets, i want to get the messages passed between these clients and server by my app running on those computers, i mean when they pass each other "hello" i want to capture the full message and then modify that message and then pass something else like "how".i search on the internet and found packets sniffers but i think they will capture packets not full text.
in short i want to get data and modify data and then send again.

Actually most packet sniffers that I've used (on Linux) also compiles the frames. Thus producing the packet content.
Try Ethereal. That should cover your needs.

Ehh... sorry, forgot that you needed to modify the frame content as well.
That might be a bit harder, even with ethereal...

Thanks for ur kind answer.
suppose my application monitors my all network activities on that computer,i.e suppose when anything is going out from computer then can i do the task of getting the contents and modifying that.

Does anyone know a way to automate the changes necessary in the stub code for bidirectional RPC ? I would like this to happen during the buildprocess. Currently i have to do them all again each time i recompile the idl-File.

i want to read some amount of data starting from some base address of a device say, 0x3f2h. how to read 256 bytes of data from that location and what should i do in order to print the contents of that memory location??

Are you sure 0x3f2h is a correct address, are you running a 16bit system? Reading from a specific memory loacation really depends on what data you want to read. Is it a string, a struct a stream.... I will presume you don't know. so best thing to do is copy the amount of memory you want into a byte array.
BYTE tmp[256];<br />
memcpy(&tmp,0x3f2h,256);

hello sir!! yes, i dont know the contents of that memory location. but yes, the memory address is correct i guess. Because, its the base address of a floppy drive. i am trying to read the data from these memory locations that provide the interface between operating system and I/O device. can u please tell me how to do it?? i am new to this and so i really need some guidance. and yes, i am writing the program for 16 bit machines. thank u.

Are you sure that the HAL will allow you to do this? Have you checked to see if there are any functions available to get the desired information?

Windows already serving administrative tools for doing this. Then why you are going to write the same code again.
Check the stuffs on MSDN Security Home[^]

Actually i want to protect a perticular drive from deleting and formatting.
And also i need programetically solution(in VC++).If you have any idea then just
write here.Any help will be greately appreciated.
Thanks

I believe this can be done by modifying registry values (in Win2k, XP and vista).
I have no clue as to how to do this in VC++, other than running .reg files, or direct modification of registry (which will need correct access rights for the registry values involved).
I've seen some of these XP-fixes on the internet, which basically is a .reg file that will update these settings.
Can't say for sure I've seen how to do this on drive-rights, but you can disable certain Start Menu features, and a lot more.
Check out the "Security Policy Setup.mmc" to see what is available. Then search msdn or google it to find the actual registry value to modify...
Just some ideas, and maybe not what you're looking for, but thought I'd mention it
Cheers,

Thanks TylerD75 for your information
Can you tell me please how can i disable certain Start Menu features?

This is the manual method, where you also will find a complete set of editable policies:
You might already have links in "Administrative Tools" on the start menu, but I don't (on XP x64 Edition).
1. Start->Run, enter mmc and press enter.
This will start an empty instance of Microsoft Management Console.
2. In the "File" menu you press "Add/Remove Snap-in..."
This will enable you to add management tasks.
3. Press the "Add..." button, and select "Group Policy Object Editor".
You will be presented with the possibility to setup Group Policy for you domain (if you have one, and is the admin of the domain) or the default: Local Policy.
Chose what you want, but I'm assuming you want the "Local Policy".
4. Hit "Finish", "Close" and "OK" to start your managing.
Now you've got all you need to modify Internet Explorer, the Start Menu, Windows Explorer (here you can disable viewing of specified drives Windows Explorer etc...).
Just have a look around in the "User Configuration" section.
A WARNING: Don't mess around with things you don't fully understand, as this could disable your users access to the MMC. (Which would render you powerless when trying to undo certain features!). If you're able, I also suggest you backup your registry before changing too much
If you want to enable or disable features with a VC++ program, you need to search MSDN or Google for individual settings you find in the Group policy manager.
This will produce the actual registry settings for the specified setting. Then make a VC++ program to modify those settings.
If your ultimate goal is to just set those settings for more than one computer (i.e. a Domain), you could accomplish this by setting group policy for the domains Active Directory. So there's no need to actually do this with C++. But if this is your goal, you should really read some active directory articles at MSDN or microsoft.
Hope this helps?
Cheers,
TylerD75

It will involve an access control list (ACL).

in MDI,you can get the mainFrm pointer like that CFrameWnd *fw = (CFrameWnd *)AfxGetMainWnd().
or you can get the childFrm pointer.
then,you can change the size of Frame like that fm->MoveWindow(CRect).
but when the width of Frame is enought small(like 123),i find that we can't change the width of Frame.
you can try like this,fm->MoveWindow(0,0,50,50);
when you execute the sentence, you can find that it no effect.
who can tell me why?

You may try SetWindowPos()

MoveWindow actually calling SetWindowPos. So I don't think that there's an alternative effect on which failed in MoveWindow. Since this stuffs are moving related
