Hi,
I want to monitor network traffic of LAN.
Basically, my current application is continously transferring data from one computer to another on LAN. Currently i have fixed the tranfer rate i.e. in my application i have mentioned tranfer rate of 32 KB.
Now i am planning to optimize my application by changing tranfer rate dynamically.
That is, i'll calculate bandwidth of LAN and depending upon the availability i'll send data.
Please help
Thanks in Advance!!
Regards,
Tony

Thanks for the help but these articles explains about monitoring bandwidth of internet whereas i want for LAN.
Also i tried googling for this topic but was not successful enough.

What do you mean by "calculate bandwidth of LAN"?
Available bandwidth is always changing.

Yeah thats what Bandwidth is always changing.
So i need to know the Bandwidth of a LAN everytime i send data.

You'd need to add something to your protocol so one or both
endpoints monitor throughput and adjust accordingly.
You have the data you need - time and number of bytes sent/received.
Maybe look up "network bandwidth throttling" for algorithms to interpret
that data.

before sending info for printing using CPrintDialog how to check whether selected printer(using printer dialog) is ready to print(attached to server) .
i m using following code for printdialog call and getting selected printer name but unable to check status of selected print is there some method ??
bool bNewDlg = true;
if (m_printDlg == NULL)
{
m_printDlg = new CPrintDialog(FALSE,PD_DISABLEPRINTTOFILE);
bNewDlg = false;
}
ASSERT(m_printDlg != NULL);
if (PrinterName == NULL) {
if (m_printDlg->DoModal() == IDCANCEL) return (-1);
m_hprinter = m_printDlg->GetPrinterDC();
CString cs;
cs= m_printDlg->GetDeviceName();
m_hprinter=m_printDlg->GetPrinterDC();
if(m_hprinter==NULL)
return;
m_numCopies = m_printDlg->GetCopies ();

What about calling GetPrinter(hPrinter, 2, ...)?

Hi all,
I am creating Win32 application in which i need to create an account with administative privileges. I am able to create an account with normal user rights.
But when i tried to create an account with administative privileges, it is giving error. So can't I create an account with admin rights directly??
Please help me out in this scenario. Any help would be greatly appreciated.
Thanks

Don't you think that this is very vague? Are we supposed to guess the error?

I apologize for such a vague post. I had tried to make it brief but was
brief more than necessary.
BTW i got solution for my previous vague post.
My next problem is to change right of current user from administrator to limited user account . That is, i want to make current user from admin to limited account. I tried to do this with NetUserSetinfo(). But it is not working for my case.
Hope for positive reply.
Thanks,
Hemang

You've done the same thing again. Why can't you tell us what exactly did you try and what does "not working" could possibly mean? The function failed? Did you check the return value to find out what went wrong? If not, why? The function succeeded, but did not give you expected results? Is your code perfect? Why don't you show the code?
We cannot read your mind, you see.
There's too less information in your post for anyone to give you any kind of helpful answer.

I am sending the code snippet that i am using to change account type from admin to limited/noraml user. The user that i am trying to restrict has been created as admin.
her is the code
int getAdminNumber(int argc, wchar_t *argv[], LPWSTR user)
{
DWORD dwLevel = 2;
LPUSER_INFO_0 pBuf = NULL;
LPUSER_INFO_2 pBuf2 = NULL;
NET_API_STATUS nStatus;
LPTSTR sStringSid = NULL;
wprintf(L"\nCalling NetUserGetinfo with Servername=%s Username=%s Level=%d\n", argv[1], user, dwLevel);
nStatus = NetUserGetInfo(argv[1], user, dwLevel, (LPBYTE *) & pBuf);
if (nStatus == NERR_Success)
{
if (pBuf != NULL)
{
pBuf2 = (LPUSER_INFO_2) pBuf;
wprintf(L"\tUser account name: %s\n", pBuf2->usri2_name);
wprintf(L"\tPrivilege level: %d\n", pBuf2->usri2_priv);
if (pBuf2->usri2_priv == 2)
cnt++;
if(strcmp((char *)pBuf2->usri2_name, (char *)user) ==0)
ChangeUserPrivilege(pBuf2->usri2_name, pBuf2->usri2_priv);
}
}
else
fprintf(stderr, "NetUserGetinfo failed with error: %d\n", nStatus);
return 0;
}
void ChangeUserPrivilege(LPWSTR csUser, DWORD csPrivilege)
{
NET_API_STATUS nStatus;
USER_INFO_1005 ui1005;
DWORD dwLevel1005 = 1005;
DWORD dwPrivilege;
wchar_t *pswzUser = csUser;
if(csPrivilege == 2) dwPrivilege = USER_PRIV_USER;
ui1005.usri1005_priv = dwPrivilege;
nStatus = NetUserSetInfo(NULL,pswzUser,dwLevel1005,(LPBYTE)&ui1005,NULL);
}
I am not getting any error for above code but at the same time not getting desired output.
Any help would be greatly appreciated.
Thanks

What is the value of nStatus after the call? Is it equal to NERR_Success?
Can you try this?
if(NetUserSetInfo(NULL, pswzUser,
dwLevel1005, LPBYTE)&ui1005, NULL)!=NERR_Success)
AfxMessageBox(_T("NetUserSetInfo() Failed!"));

I have console based appliacation. So i used following code to determine it.
nStatus = NetUserSetInfo(NULL,pswzUser,dwLevel1005,(LPBYTE)&ui1005,NULL);
if(nStatus != NERR_Success)
fprintf(stderr, "NetUserSetInfo failed with error: %d\n", nStatus);
And above code gives me following error.
NetUserSetInfo failed with error: 87
Any suggestion. Please help me.
Thanks,
Hemang

Why don't you through the documentation and find out what the error means? The return value can be one of the 9 return codes provided in the documentation in case of failure. I don't feel like offering any help if you can't even look up the documentation.

Have you verified the second argument is what you expect? Have you tried a string literal?

eg. Chinese,
I can't not input chinese when the EDIT has ES_PASSWORD style

This is not an answer to your question, but I'm just curious. Don't take it personally.
Are you setting a Chinese password? 
It must be difficult to type those characters even when you see them. How possibly can you be sure of what's being typed when all you see would be asterisks.

Usually you have to type two times the new password. For a Chinese one, you have to do it eight times.
