call the CListCtrl::Arrange() method after you size the list control.

You mean a behaviour similar to explorer? you can use ShellExecute() for this.

Hello everyone,
I heard when define a struct, it is important to make the size of the struct memory aligned.
For example,
<br />
struct foo<br />
{<br />
char p;<br />
char[3] align;<br />
};<br />
<br />
struct goo<br />
{<br />
char p;<br />
};<br />
struct foo is better than struct goo, even if we only use member p.
Allocate 3 bytes to align with memory. But I do not know why make memory aligned is better. Any reasons? (for example, prevent memory from running out?)
thanks in advance,
George

Putting in your own padding is usually superfluous. The compiler will do it for you, and it will match up the padding to the alignment requirements of the CPU that you are targetting.

Thanks Mike for answering another question. 
I want to know if the compiler does not do it for me directly, why do we need to pad, and what are the dis-advantage if we do not pad?
regards,
George

Read this[^]

The link does not work, could you provide an alternative one?

Nibu, I have checked some other resources. It seems that using memory alignment will improve performance by others' points.
But I do not know why alignment will make memory reading operation faster. In my case, foo needs to fetch 4 bytes and goo needs to fetch 1 byte. Even if each time, CPU fetch 4 bytes, I think they should be the same performance, right?
Why do you think memory alignment will improve performance? An example?
regards,
George

Did you go through the article. It has some good explanations.

hi:
when i am lisetening to Sharing printer the function of FindNextPrinterChangeNotification wii be fails,and GetLastError()
saying "the handle is invalidation" .
if the prinnter is local ,FindNextPrinterChangeNotification will obtain information about the change.
my code is here
h_change_notification = FindFirstPrinterChangeNotification(h_printer,
PRINTER_CHANGE_JOB ,//0,PRINTER_CHANGE_ALL,
0,
&printerNotifyOptions);
if(h_change_notification == INVALID_HANDLE_VALUE)
{
MessageBox( NULL, "FINd FIRST Error", NULL,MB_OK);
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
GetLastError(),
MAKELANGID (LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL);
MessageBox(NULL,"FindNext Error",lpMsgBuf,MB_OK );
this->m_listeningStatus = LISTENING_OFF;
return FALSE;
}
this->m_listeningStatus = LISTENING_ON;
while(endLoopInd == 0)
{
return_value = WaitForSingleObject( h_change_notification,50);
switch (return_value)
{
case WAIT_OBJECT_0:
return_value = FindNextPrinterChangeNotification(h_change_notification,
&dw_change,
&printerNotifyOptions,
(void **)&printerNotifyInfo);
if(return_value == 0)
{
//error handling
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL);
MessageBox(NULL,"FindNext Error",lpMsgBuf,MB_OK );
this->m_listeningStatus = LISTENING_OFF;
return FALSE;
}

Maybe use WMI...check out the Win32_BaseBoard WMI class.
There's many articles here on CP about using WMI if you need them.

Can you give me some code? thank you.

Type in "WMI" in the "Search" box above and click "Go!". You can then narrow the search to just
C++ related articles 
Here's a link to one article: Getting Information from WMI in Visual C++[^]
As you can see, WMI coding in C++ gets a bit wordy.

You can use the WMI class Win32_MotherboardDevice

Hi all,
I'm using C to write a socket program.I want to add in that server program that it will accept only the password from the client if it's "mypassword":
i'm not writing any client program. the client will be the built in linux Telnet program
so the session will be between the server and client as follows
1. telnet 192.11.11.9 password "mypassword".
2.then the server if recieved the password "mypassword" it will connect if not it will close the connection.
I want to know how i can make the server program recognize that the pasword is right or wrong..how i can write it in the server
Thanks

Hi,
Telnet clients doesn't connect just like that - for telnet connection is special protocol - helping documents:
Telnet protocol: RFC 318
Telnet protocol specification: RFC 854
Telnet options specifications: RFC 855.

You could write an interactive login sequence.
For example your server sends the text line "Enter your authorisation" immediately when a client connects, then evaluate the first newline terminated response from the client. However, this simple approach works with most telnet clients only on a non standard port (other than port TCP 23)... I would strongly recommend to implement the full telnet protocol or at least look for IAC sequences in the server code (RFC 854).
Hope this helps.
