Hi
I'm looking to write a partition cloning utility,
much like Norton Ghost in the sense of being able
to copy only the USED sectors from one partition
to another.
I'd like for that utility to be able to work
mostly with FAT32 formats, even though NTFS
and/or EXT2 or EXT3 (f/Linux) would be nice too 
1. Programming background:
- I've had a bit of C/C++ programming experience,
but my Pascal skills are better.
- I'm not exactly familiar with Assembly language,
but if some Assembly code were to find its way
into a C/C++/Pascal wrapped function, using a
technique called 'inline Assembly' (I think) and
all parameters and/or function results were to be
passed in or returned in the hosting high level
language, that'll work
2. Problems:
- how do I read a hard drive's FAT, in order to find out
which sectors are used and which ones aren't?
+ My idea for my utility is to be able to tell that, right
upon startup - much like what Microsoft's MSDOS Scandisk
does when it's ready to do its surface scan - where
there's a nice form (or window) appearing on screen,
and a whole bunch of differently colored columns are
in it, representing the examined disk's data layout.
+ Obviously it has to be done very quickly; I know I
could scan sector by sector, but the downside is
that it may take forever if there's a large partition
that is mostly empty.
- Another problem is an option that I'd like to add in,
which would have to do with displaying, and perhaps
catalogging all filenames and pathnames that get
read along the way, during a clone. If I were to refer
to Norton Ghost again, then it has a command line switch
allowing the user to generate some sort of a filename list.
3. Available source codes:
- I've checked out FreeDOS Defrag and Scandisk,
where both utilities were written in C or C++
plus another Scandisk version written in Turbo Pascal.
- Unfortunately, the two C/C++ utilities didn't even compile;
The Pascal version, however, did.
- I booted the PC via some BootCD with Win98 system files
and attempted to run FreeDOS Scandisk on pure MSDOS mode,
but, unfortunately it would report my either FAT32 partitions
as non-DOS disks.
Any ideas on how clone USED sectors only?
Thanks in advance

No Sir,
No college project, nor do I want to hire anyone 
This is something I wanted to see if I can write on my own
and then add in some functions that I'd like to have.
Any ideas?
Cheers

Hi,
I 'd like to know what does the dll and lib files in OpenCv contains?
and how can i explore their codes?
i know that openCV is an open source library so, why it contains dlls and libs files?
is it considered closing the source code.
Thank you

| Willow Garage is the offical maintainer of OpenCV now. Here's[^] where you start to find documentation and source code. The source IS available. I'd suggest you buy the book and read it to get started on what the library contains.

I have the manual of openCV and i have some sort of experience with it.
but i am talking about some lib and files we include it in the VC++ directories.
i gonna run C++ code based on openCV on NOISE|| mirceoprocessor.
so, i need to recompile these lib and dll files.
I hope my point is clear now. Ahmed Ismail

I'm not familiar with that processor. I work with OpenCV 2.0 and have done my own projects for VC++ 9.0 to build static libraries under Windows. Basically, if you look at the subdirectories under src, there are 5. CV, CVAux, CXCore, HighGUI, and ML. I built a lib using the source files from each folder. You'll have to set up your build environment to point to the correct lib files. In 2.0, this is just include\OpenCV, however, they did change the directory structure in 2.0 from earlier versions.
If you want to build DLLs, you'll have to set up a similar plan but with the output being the DLLs and link libraries. There are some #define statements that need to be set properly to properly export the functions and classes.
You may have better luck getting support in the OpenCV Group on Yahoo Groups rather than here.

Hi
I'm having difficulties compiling TrueCrypt 6.3a,
possibly because I'm not quite sure as to how to
set up all extra libraries/tools.
1. The PC's specs I was using to compile were:
- Pentium 4 w/2gb RAM
- WinXP Pro w/s.p.2
- MS Visual C++ 2008 Pro
- RSA Security Inc. PKCS #11 Cryptographic Token Interface 2.20
- NASM 2.07 (Win32) installed
2. The things I wasn't sure about were:
- For MS Visual C++ 2008 Pro:
+ was s.p.1 really necessary, or could I've
done without? It's just that, as I recall,
when I tried to run an update with that s.p.1
thing, it took well over an hour to complete,
and as far as I knew all it did was to add in
some Silverlight functions. Obvioulsy I'd
rather skip this 1 hour wait, if that s.p.1
is not absolutely necessary.
- For NASM 2.07:
+ I added NASM to the External Tools menu command
of the MS Visual C++ 2008 Pro IDE, and it did
appear, after that as yet another menu command,
however upon compilation there were several error
messages claiming that NASM was not available,
even though its path seemed to be correct.
- For MS Visual C++ 1.52:
+ wasn't this an Win 3.1 compiler?
+ what is it good for anyways, if TrueCrypt is
to be compiled with a .NET compiler in the
first place?
- For Gzip compressor:
+ is there a utility or DLL to install/register?
+ how would any of the compilers (if any) recognize
or make use of that Gzip thing?
- For PKCS #11 2.20:
+ what folder was I supposed to put it in?
+ I did declare an environment variable of type 'System'
for 'PKCS11_INC' with the path pointing to the contents
of one of the ZIP file: there were a bunch of '.h' files.
- For Windows SDK for Windows 7:
+ what if I was to use TrueCrypt only on WinXP?
neither Vista, nor Win7, at all?
- For Windows Driver Kit 7.0.0:
+ would this have been the replacement / only driver SDK available
for all Win versions from now on? In other words, what if I want
to use TrueCrypt on a Win98 machine - do I still have to compile
it on an NT based system?
Any ideas on how to get TC to compile?
Thanks in advance

I want to Create CMFCRibbonButton control with custom width independent of it's caption length.
and even I want know if I could change their width dynamically (at running time)
|
|
|
|
|
Try CMFCRibbonBaseElement::Get/SetRect(..)
To my intuition
it should be used at creation time,
or you will call something like "ReAdjustLayout" for the parent bar/pane
after the setting of the rectangle at RT... virtual void BeHappy() = 0;
|
|
|
|
|
It was so surprising to me when i found that actually these two methods (CMFCRibbonBaseElement::SetRect and CMFCRibbonBaseElement::GetRect) do nothing, even after creating your ribbon element and put it in the ribbon menu you can't retrieve the dimensions of your element with CMFCRibbonBaseElement::GetRect and the only thing it gives is a rect object with zero dimentions

Hello,
I would like to get some ideas on writing a stack library using C language, that will as generic as possible
It should support different data types - (handle strings, ints, chars, doubles, and other misc data types), different stack sizes, etc...
I am open to hear about any ideas that may come, (See prototypes, and get some code if anybody happen to have it already) and/or will be happy if anyone can referee me to places with this issue already solved.
Thanks.

Hi All,
I am trying to add a cmd functionality into my app, however it's not working very well and I am looking for alternate methods. What I'm going right now is taking an input command and using CreateProcess with cmd /C *command* > outputFile, then reading the file and displaying the output. However, the problem with this approach is that if I want to start an app, lets say Notepad, I would not be able to do anything else until Notepad closes. As well, the cd command is rendered useless, as when cmd exits and I call another command, the new cmd created by CreateProcess is still at the same directory.
Does anyone have any suggestions for a different approach - perhaps somehow piping the input/output from the cmd window directly to my app?
Thanks very much.
|
|
|
|
|
Oh, and I can't distinguish between a successful command and an unsuccessful one (whether that command even exists or not).
|
|
|
|
|
| Have you tried to create console for your process with AllocConsole? Life is a stage and we are all actors!
|
|
|
|
|
No, I haven't because I don't see how would I receive the output of any command with that method. I don't see how I can input stuff into it either...
EDIT: aha, I see now. Going to try it right now. Thanks! modified on Saturday, March 13, 2010 6:40 PM
|
|
|
|
|
Okay, that doesn't work either because the only ways I can actually call the command is ShellExecute or system() - they both cannot change the current directory.
I'm going to try ShellExecute instead now, I think that might work.
Thanks again for your help.

Start the command directly but use pipes to redirect it's output. See this[^] article for details.
As for telling when the program is done use the process HANDLE returned in the LPPROCESS_INFORMATION structure passed to CreateProcess. A process HANDLE can be passed to one of wait functions such as WaitForSingleObject because it becomes signalled when the process has finished executing. Also note that a common mistake made by people is not to close the process and thread HANDLEs when they're done with them (or not at all).
Use GetExitCodeProcess to retrieve the return code.Steve

Ok sorry for being dumb but I have been staring at this for a couple of days now and I am getting nowhere.
My dialog has a menu with a couple of controls, the main one being a CTreeCtrl.
I have captured the OnCancel() to prevent accidental closure but I notice that the 'Enter'/CR key causes the app to close and I have no idea why? It triggers an orderly close bypassing the OnCancel().
I know I have missed something but I just cannot see what.
Any pointers?
Many thanks
Alan

Please ignore this.
Just figured out that I did not have a handler in place for the OnOK. Thus the default behaviour was being called which closes the app.
Doh!
Sorry for wasting your time guys.

Hi,
I have two classes, MainDlg.cpp, and Game.cpp . My MainDlg.cpp file is responsible for TCP communication, and it works fine on its own. I initially start MainDlg.cpp and then I start the Game.cpp class from there. Iam trying to call the DoSend() (on MainDlg.cpp) method from the Game.cpp file and it just results in a SOCKET_ERROR !
Just for experimentaion I've tried to call a method on MainDlg.cpp from Game.cpp to display a simple MessageBox and it works, so the problem is not with the class object I created.
This is how I created/call the Game.cpp object on MainDlg.cpp
Game* game = new Game;
game->Create(Game::IDD);
When the Game.cpp dialog comes up, this is how I execute the method on MainDlg.cpp:
CMainDlg* Main = new CMainDlg;
Main->GetResults();
In MainDlg.cpp :
GetResults method: <-- Works fine when run locally
void CMainDlg::GetResults()
{
Message_PDU Message;
Message.iMessageNumber = 80;
DoSend(Message);
}
DoSend Method: <-- Works fine when run locally
void CMainDlg::DoSend(Message_PDU Message)
{
int iBytesSent;
iBytesSent = send(m_iSocket, (char *) &Message, sizeof(Message_PDU), 0);
if(SOCKET_ERROR == iBytesSent)
{
MessageBox("Failed to send","Client");
}
}
Any help will be really appreciated!

Did your applications performed correctly the preliminary steps (i.e. there's an established connection between client and server?)?
