I don't knosw what it can be, I use this and it works for me... I export one f(x) in the DLL that is called bActivarHook(bool bActivar); what means bActivateHook(bActivate); (it was in catalan  ) and inside that f(x) I've placed this code:
DLLSCT_API bool bActivarHook(bool bActivar )
{
if(bActivar == true)
{
hHookTeclat = SetWindowsHookEx(WH_KEYBOARD_LL, HookTeclatLL, hInstDLL, NULL);
return (hHookTeclat != NULL);
}
else
{
if(hHookTeclat != NULL)
{
UnhookWindowsHookEx(hHookTeclat);
return true;
}
else
{
return false;
}
}
}And I call this function from my app (In my case the caller app is a service, but it must do the same...)
well hope this helps...

I created a program that opens and saves the file using CFileDialog class.
I created a program that opens and saves the file using CFileDialog class.
However, whenever I save some files using this program, files always are hidden and saved as system files.
So, I checked the attributes of CFileDialog of my code.
I only used OFN_OVERWRITEPROMPT in dwflags.
Does CFileDialog class originally save files wih those attributes (hidden and system files)?
Please help me.
I don't want to save files as hidden and system files.
Thanks in advance.

CFileDialog doesn't save the files at all - it just allows the user to select the file to save.
You normally do something like this:
CFileDialog dlg( FALSE, ... );
if ( dlg.DoModal() == IDOK )
{
// Do the save here
CFile f( dlg.GetFilePath(), CFile::modeCreate|CFile::modeWrite|CFile::shareExclusive );
// Write the file...
f.Close();
}
Post the code that actually is performing the save function (after the CFileDialog's DoModal() method returns), and we'll see if we can spot anything wrong.

Thank you for kind explanation.
It was totally my fault.
Actually, I used another header file to write into file using createfile and there were hidden/system attributes in #ifdef~#endif.
Thank you!!!

I am creating an internal app framework (for company apps).
Using C++ will facilitate my task but I have to make the framework / library usable for C programmers.
Any ideas?

use extern "C" into fn prototypes (of course they can't be class members)
t!
.h:
#ifdef __cplusplus
extern "C"
{
#endif /* __cplusplus */
int my_fn(void);
#ifdef __cplusplus
}
#endif /* __cplusplus */

Thats it! Thanks. I thought I had to specify function call argument passing (__cdecl, __fastcall, etc) just as Dr John Maddock's Regex++ library.

It's often a good idea to be specific about the calling convention when exporting from a DLL; if the client program is compiled with a different default convention (using the /Gd, /Gr or /Gz switches) from your DLL it either won't link correctly or will potentially crash at runtime, due to erroneous stack manipulations.
__stdcall is marginally smaller (typically one ADD instruction) at the call site than __cdecl, but __cdecl can handle variable argument lists and is marginally smaller in the function implementation. The ADD instruction is used to reset the stack pointer after the call back to where it was before the compiler started PUSHing arguments. More info in John Robbins' excellent Debugging Applications books (I just bought the most recent one, Debugging Applications for Microsoft .NET and Microsoft Windows - there's a mouthful).
This only applies to desktop Win32 running on IA32 processors; Windows CE on IA32 always uses __cdecl, while other processors only have a single calling convention. Most RISC processors use a calling convention sort of like __cdecl but with the first n arguments passed in registers. This is also true of AMD64 (first 4 arguments passed in RCX, RDX, R8, R9 or XMM0-3 if floating point) and IA64 (first 8 arguments passed in the rotating portion of the register file).
[Yes, I know the processor names look a little unfamiliar; specifying 'x86' isn't very helpful any more because 64-bit 'x86-64' code works differently. AMD now wish Opteron/Athlon64-compatible code to be known as AMD64.]

Hi. I am in desperate need of help when it comes to MDI child windows. I need to add controls to them, but I don't know how. I've been using CDialogBar as a replacement, but it is VERY limited compared to an MDI child window. A code snippet would be appreciated, but at least telling me which CWnd is supposed to be the parent of the controls would be helpful.

Typically CChildFrame which is derived from CMDIChildWnd. If you have a Doc.View application then you work with CView derived classes, which are children of CMDIChildWnd.
Hope that helps.

Look up CFormView in MSDN. There are many samples in MSDN and here.

Hello, everyone.
I have a library with a class A (has two static functions f1 and f2) and B (calls functions of A), I can compile it, with no problems. Then I am using this library in my program and during the linking I have an error (see below for the log) that static A::f1 can not be found for B.obj.
Maybe someone knows why one function could be found, while the other not? I simplified my problem, because I have a library with a lot of classes and it worked before. I had this problem some time ago but I played with the order of the inclusion of the header files and I got rid of the problem, now I can not help it.
This is the whole message:
Linking...
SJManagers_D.lib(SJGmeMan.obj) : error LNK2001: unresolved external symbol "public: static void __cdecl CSJSndMan::PlaySoundA(unsigned int,bool)" (?PlaySoundA@CSJSndMan@@SAXI_N@Z)
Thanks.

Is your function actually called PlaySoundA() or PlaySound(). The reason I ask is that in one of the standard windows header files, a lot of the standard API methods are #defined to function beginning with A (for ANSI) or W (for Wide). I think that PlaySound is one of them. If this is what is happening, then it is possible that the rename is not taking place inside your library, but does take place when the library is used (i.e. the .lib file has PlaySound() because the rename didn't occur, but the app is looking for PlaySoundA() because a rename has occurred).
You can check this quickly by renaming PlaySound() to something like PlayMySound() and recompiling.

Is it possible to make a trojan with code progject??? Im just asking cause im planning to bulid one with VC++ i think I ll be the first one making a trojna with VC++ lol..

yea its very well possible, i made one of my own, its crappy though and uses MFC. The beauty about ur own trojan is that virusscanners don't detect it as one (as long as it doesn't get widespread)

OH ok, Thats pretty cool that you could make a RAT, I heard is better making RAT in delphi??? but i like MS vC++ better I want to make a nice one is there any tuts on making a trojan on C++?? if there are please post the link
Thankz in advance

i don't know any tuts on making one, i think most people just make them up, and there isn't like a base model for a RAT because the functions differ from file transmissions to showing/hiding the startbutton lol (which is really stupid according to me btw)
I would suggest u pick up on winsock programming first, u need to know how to program asynchronous sockets as well as blocking sockets, u can find all the info u need at the winsock programmers faq, just type that in in altavista and u'll get there, they have some samples, this is without mfc though, but its the best way to learn.
The problem these days though are firewalls and shared connections and getting the ip since messengers use a central server u cant get the ip as easily. So what i did with mine was when the RAT ran it logs in to a public chat server (like irc for example, but mine doesnt use IRC allthough it should be possible i guess). Then when the RAT is running, u'll know cause u see the nick is logged into the chat, and u can also get the ip through the chat, so u can try and direct connect, however if there's a firewall u wont be able to and u would need a direct connection to transmit files. But i also thought of that too, and its fairly simple, u just make it so that the RAT listens on the chat for commands, so u can give it commands through the chat, u could even make it so that it would only take commands from a certain chat user so other people wont take advantage. My RAT for instance has a function to download files from the web, so if i want a file on the target computer but i cant direct conect, i just upload the file to my webspace, and give the command through the chat to download that file. The other way around is possible as well, u give a command to upload a file to webspace, of course this involves ur password and login being in ur trojan, so i suggest encrypting ur code or use free webspace so that when ur trojan gets into wise hands they dont run away with ur webspace lol.
Anyways, i hope that helped, maybe i'll write a tut about making a RAT one day

I found this short description about SSL:
You enter a URL such as https://www.mysite.com in your browser window. The https indicates that you want your browser to initiate a secure session with the server
The server responds by sending the site's certificate
The browser checks the certificate information for validity
The browser then creates a session key, which is encrypted with the server's public key, and sends it to the server
The server then decrypts this information using it's private key
Both the browser and server are now using the same secret session key, and the little lock icon will appear on your browser window. All further information sent between the browser and the server will be automatically encrypted, as long as you continue using the https:// protocol.
-----------------------------
whats the private key?? i mean, ur browser generates a session key, its encrypted with a servers public key, but for ur browser to get a public key, it would have to be sent over the network too right? so if that is intercepted, and u encrypt ur session key and send it, and someone intercepts that too, they can decrypt ur session key right? because they already intercepted the public key or they are able to get it (if its static). So i'm guessing the mystery is in the private key, allthough i don't see how it can be different from the public key, i don't seem to understand. Because if the private key is different from the public key, the server will not decrypt it into the same session key as ur browser generated right?
Could anyone clarify this?
Thank you
Kuniva

A public-private key pair works as follows.
What you encrypt using the public key can only be decrypted using the private key.
And what you encrypt using the private key can only be decrypted using the public key.
Thus you sign using your private key, because people can verify that this is actually you, by decryping the signature using the publicly available public key.
And when you want to send confidential info to the server you encrypt the data using the public key. Now the data can only be decrypted at the server because only they have the private key.
It is nearly impossible to figure out the private key given a public key. Perhaps if you run a brute forcer on a super computer for a few 1000 years you might crack it.

Nish
