Probably you have to change the following lines
CString str='s';
m_UserVariable.Processattendacne(str);
to something similar to (error checking omitted)
BSTR bstr = SysAllocString(L"s");
m_UserVariable.Processattendacne(&bstr);
SysFreeString(bstr);
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I have this question. I'm an Info Tech student in Uni. We were assigned to a project that involves audio.
We wish to write a new audio encoder which transforms/encodes an mp3 file to a custom format, say *.btm.
And also a plug-in which will be able to decode the *.btm file and is compartible with any media player as long as the plug-in is there.
I was wondering if you could give me a tip on how it works and how to go about it.
We are working on a school project with my team mates.
Please i would appreciate it if you send me some helpful codes (C++) as well.
Thanx you.
Samson Akanet.

Try to search http://sourceforge.net[^] with the name lame. This is a library for converting mp3 files and is, for sure, in source code.

Hi,
The CSocket class has been widely publicised as being buggy: the advice has historically been to use a 3rd party control or write your own.
Has the CSocket class with MFC supplied with VS2008 been updated, or is the current advice to use a 3rd party control / write your own?
Can anyone reccommend a 3rd party / free TCP wrapper? (Yes I'm aware there are plenty of example applications here on CP, but which one is the best)
thanks,
Mark.

I don't know how buggy it is - it does what it's documented to do.
It's a very simple designed wrapper around the Winsock APIs. It
works fine for simple socket tasks (on one thread).
If you need performance you'll need asynchronous communications.
You can use the CAsyncSocket - it works pretty well and it's a very
thin wrapper around the socket APIs so you could use straight APIs
almost as easily.
The important thing is to know how sockets work and how to use the APIs.
Then the MFC classes will make more sense and you'll be able to use them
effectively. The source code for those classes is the ultimate documentation,
and it's relatively easy to read.

i have wrote code logon admin in limited user like the following
****************************************************************
BOOL CEKLoaderDlg::OnLogonUser()
{
STARTUPINFO si;
PROCESS_INFORMATION pi;
HANDLE hToken;
LPCTSTR lpszPrivilege = "SeTcbPrivilege";
BOOL bEnablePrivilege = TRUE;
BOOL bDisEnablePrivilege = FALSE;
LPDWORD lpExitCode;
char* username = "administrator";
char* password = "xxx";
char* cmdLine = "cmd.exe";
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
static LUID luid;
static TOKEN_PRIVILEGES tp;
if(!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken))
{
AfxMessageBox("OpenProcessToken() error \n");
}
else
// AfxMessageBox("OpenProcessToken() is OK\n");
//********************* Enabling (Disabling) privilege ***************************
// Call the user defined SetPrivilege() function to enable privilege
if( SetPrivilege(hToken, lpszPrivilege, bEnablePrivilege))
{
if(LogonUser(username,".",password,LOGON32_LOGON_INTERACTIVE,LOGON32_PROVIDER_DEFAULT,&hToken))
{
if(ImpersonateLoggedOnUser(hToken))
{
if(CreateProcessAsUser(hToken,0,cmdLine,0,0,FALSE,NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW,0,0,&si,&pi))
{
// editbootini();
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
TerminateProcess(hToken,0);
return TRUE;
}
else
{
AfxMessageBox("Failed");
}
// Cleanup...
if( pi.hProcess != NULL )
CloseHandle( pi.hProcess );
if( hToken != NULL )
CloseHandle( hToken );
}
}
else
{
AfxMessageBox("Administrator password is wrong");
exit(0);
}
}
SetPrivilege(hToken, lpszPrivilege, bDisEnablePrivilege);
return TRUE;
}
Then wrote code for restart like the following
*********************************************
m_stcCalling.SetWindowText("Restarting Your System");
AfxEnableControlContainer();
HANDLE hToken; // handle to process token
TOKEN_PRIVILEGES tkp; // pointer to token structure
BOOL fResult;
if (!OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
*******************************************//return failure
{
log("Error Type : Error in Restarting");
log("Severity Level : Critical");
return FALSE;
}
// Get the LUID for shutdown privilege.
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
&tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
// Get shutdown privilege for this process.
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
(PTOKEN_PRIVILEGES) NULL, 0);
fResult =InitiateSystemShutdown(NULL, "System is being restarted ", 0, TRUE, TRUE);
if (!fResult)
{
fResult = GetLastError();
log("Error Type : Restarting Failed");
log("Severity Level : Critical");
return FALSE;
}
return 1;
}
But restart wont done .why?

Please indent the code and use appropriate tags for the code blocks. It is very difficult to read your code.

Try installing it. That installation is necessary if we want to run a VS 2005 exe in a OS where Visual studio 2005 is not installed.
Also confirm that you are trying to run the release version of the binaries.

Isn't it sufficient to create an installation along with necessary dlls found in the Program Files\Microsoft Visual Studio 8\VC\redist\x86 folder?
Have you tried out this way? Just curious.

I havent tried that way. Since those binaries are implemented as side-by-side assemblies, I guess it will be little difficult to include them in the installation.

I am making a chat application. I need to send & recieve emoticons/smileys. I am getting their codes. What to do to retireve the smileys properly
Thanks In advance

What do you mean exactly ? Emoticons are just a specific combination of symbols (e.g. : and ) ). Those symbols are then interpreted by your application and replaced by a small image representing the emoticon. But you have to do that yourself.

Thanx! I will try to do it.

Use the api - SetFileAttributes() by passing FILE_ATTRIBUTE_HIDDEN as parameter.
