Framing a window - Not at creation [modified]

Hey,

Okay, bear with me. I'm not sure if what I want to do is called "framing" but that is what I will refer to it as. Most windows in Microsoft Windows have a frame, the frame (usually) has three buttons, minimize, maximize/restore down and exit. If you click 'restore down' the window has a complete frame and can be moved by dragging the mouse. I want to be able to create a frame around a window that I resize, please note that I need to do this from a dll that I inject into a process; my code doesn't create the original window.

Below is an image of what I want to do, I really hope you understand Poke tongue | ;-P

I'd really appreciate some help with this, I can't seem to get it working :\

Thanks for your time Smile | :)

Maybe you could use SetWindowsLong + SetWindowPos (with SWP_FRAMECHANGED flag enabled).

Look:
SWP_FRAMECHANGED
Applies new frame styles set using the SetWindowLong function. Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.

Monitoring network traffic on LAN using VC++

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

What do you mean by "calculate bandwidth of LAN"?

Available bandwidth is always changing.

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 no special printer-dialog is given, we take the standard printer-dialog
    if (m_printDlg == NULL)
        {
        m_printDlg = new CPrintDialog(FALSE,PD_DISABLEPRINTTOFILE);
        bNewDlg = false;
        }
    
    ASSERT(m_printDlg != NULL);

	if (PrinterName == NULL) {

		// which printer ist desired, and how much copies?
		if (m_printDlg->DoModal() == IDCANCEL) return (-1);
		m_hprinter = m_printDlg->GetPrinterDC();
	
		
		
		CString cs;
	cs= m_printDlg->GetDeviceName();
	 // AfxMessageBox(cs);
	  m_hprinter=m_printDlg->GetPrinterDC();

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

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,

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.

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.

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.
