this tool will try to detect the compiler (and the cryptor or exe modifier)

I know the linker writes information to the EXE that can be retrieved, but are you sure that the compiler does too?

I only know that every exe has a signature bytes at the entrypoint of the exe. (i mean that the first 128 bytes at the entrypoint are the signature bytes, they help to identify the compliler). And these signature bytes are modified by the protectors, packers.

winsock.h problem

newbie534520-Nov-05 20:09

I am trying to incorporate headers from one program into another. The host program compiles fine until I add my stdafx.h which includes:

#include afxwin.h // MFC core and standard components
#include afxext.h // MFC extensions
#include afxdisp.h // MFC Automation classes
#include afxdtctl.h // MFC support for Internet Explorer 4 Common Controls
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include afxcmn.h
//(syntax edited for posting)

it then generates errors such as these in which there seems to be an ambiguity between winsock.h and winsock2.h:

c:\Documents and Settings\Brenaman\Desktop\UAV Simulator\use\SourceCode\use_ios\Globals\globals_socket_ext.h(13): error C2146: syntax error : missing ';' before identifier 'socketData'

c:\Documents and Settings\Brenaman\Desktop\UAV Simulator\use\SourceCode\use_ios\Globals\typedefs.h(41): error C2501: 'gameport::capability' : missing storage-class or type specifiers

c:\Documents and Settings\Brenaman\Desktop\UAV Simulator\use\SourceCode\use_ios\Globals\globals_socket_ext.h(15): error C2501: 'recvSockAddr' : missing storage-class or type specifiers

I've tried various things:

#define _WINSOCKAPI_ in various places to disinclude winsock.h in windows.h.
Editing windows.h to include winsock2 instead of winsock.
Various #include sequences.

Thank you in advance for any help.

Did u try changing the seqence of the include fine
i also faced the same problem with the socket file,
i dont remeber what i did to solve the problem but
the stdafx if defined before the winsock header file
I have declared the Objects of winsock as global variables.

As a rule, you don't #include stdafx.h in other .h files; you just make it the first #include in your .cpp files.

DON'T modify windows.h. Ever. Millions of people use it, as-is, perfectly successfully without editting it.

Take a look at the winsock samples to see what you're doing wrong.

Do you know where to locate redistributable DLL of VC++ 8 (nov 2005)?

How to remove or ignore a windows 2003 dialog ?

Hello Friends

I have Windows 2003 Server Installed on my Server. Whenever my server goes off or electricity problem and server gets restarted automatically, at the end it asks for the reason why server was rebotted giving one dialog for writing one comment.

I want to overcome this problem, so is there any setting or any way such as to write some service or something which automatically removes that dialog or I don't get dialog or something else....

Any solution is most welcomed.....

I have written this question in VC++ section as I think using VC++ it might be possible to kill that dialog or like that.......

Thanks in advance.

U can create a programe to get the handle
of the dialogbox window . By using this
handle u can close the window.
How to identify the window is by using the
window text.
This will work fine . Hope so u get it ....

									IID_IImnAccountManager, (LPVOID*) &m_pAccountManager);<br />
  if(FAILED(hr)) <br />
  {<br />
		MessageBox(_T("Error creating IImnAccountManager."), _T("Demo Error"));<br />
		EndDialog(1);<br />
		return FALSE;<br />
  }<br />
<br />
<br />
  <br />
  m_pAccountManager->Init(NULL);<br />
  <br />
<br />
  ACCTTYPE  acct;<br />
  ULONG     ulAccounts;<br />
  m_pAccountManager->GetAccountCount(acct,&ulAccounts);<br />

but after last line it gives error

After stroking SHIFT key five times, one dialog pops up to notify if to enable the sticky keys.
Do you know some way to disalbe this function and let it not shown when stroking the SHIFT key?
Thanks in advance!

Go to Control Panel->Accessiblity Options->KeyBoard tab

Uncheck -> (Use StickyKeys)

Click the corresponding Settings button of the settings section.
UnCheck -> (Use ShortCut)

That's it.

I have known that way, however, implementing it by progamming is my favorate. Smile | :)

Have you other ways, by means of coding or offer an API function?

Such as in WinCE(Only my program need run in windows XP):
===============================
STICKYKEYS skf;
BOOL bSuccess;
// Fill in the members of the STICKYKEYS structure.
skf.cbSize = sizeof(STICKYKEYS);
skf.dwFlags = (SKF_AVAILABLE | SKF_STICKYKEYSON | SKF_AUDIBLEFEEDBACK);
// Call SystemParametersInfo with the SPI_SETSTICKYKEYS flag.
bSuccess = SystemParametersInfo(SPI_SETSTICKYKEYS, sizeof(STICKYKEYS), (LPVOID) &skf, 0);
