hi i had written the code to block the specific port using packet filtering API,all work fine but "Pfbindinterfacetoindex" execute successfully but did not block the port so i googled and find another API pfbindinterfacetoindex but it still fails the only problem could be here where give index

GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE) malloc(sizeof(PMIB_IPADDRTABLE));
GetIpAddrTable(pIpTable,&dwIface,FALSE);
for (pIpAddr = &pIpTable->table[ dwIface = 0]; dwIface < pIpTable->dwNumEntries; ++dwIface)
++pIpAddr;

PfBindInterfaceToIndex(ihandle,pIpAddr->dwIndex,PF_IPV4,(PBYTE)ip);

tell me what is wrong with this why this is not working i had spend atleast a 1 and half week on that but was failing.

Maybe instead of

GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE) malloc(sizeof(PMIB_IPADDRTABLE));
. . .

you should try this:

dwIface = 0;
GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE)malloc(dwIFace);
. . .

I hope it helps.

ClassView Clutter in eMbedded Visual C++

My project's Classview has become cluttered with a lot of classes and global functions. Many of these are used internally by a component. Is there a way to remove the ones from Classview that I find unnecassary. I am using Microsoft eMbedded Visual C++. Thanks for any help.

You can create folders in ClassView - right-click the project and select New Folder. You can then drag classes into the folder. Unfortunately you can't manage global functions in this way.

An alternative is simply to remove the headers from the project. They aren't required to be part of the project in order to compile - dependency analysis will pick them up. Obviously you should not remove them from source control, if you're using IDE integrated source control.

Stability. What an interesting concept. -- Chris Maunder

Sort your items before putting them in the COleSafeArray container, or use Excel's automation features to sort the items after they are stored in the xls file. COleSafeArray doesn't have any built-in sorting functionality.

I am using this function, but not getting event when mouse moves over button.
The code i am using is,

TRACKMOUSEEVENT track;

track.cbSize = sizeof(TRACKMOUSEEVENT);
track.dwFlags = TME_HOVER | TME_LEAVE;
track.hwndTrack = bHandle; //handle to the button
track.dwHoverTime = 1000;

_TrackMouseEvent(&track);

And i am checking WM_MOUSEHOVER, WM_MOUSELEAVE messages.
Is it correct. thanks for ur suggestions.

You've not provided nearly enough information. For starters, what code do you have in place to create/display the dialog?

Blew is my code:
CELinkConfiguratorView is the view of my SDI application,Online() is the handler message of a menu, CCBrowseOnline is the class of a model dialog.
when click the menu,the the DlgBrowse dialog should be poped up,but it didn't pop up sometimes .but it poped up after I press the Alt button on the keyboard. why?how to resolve this problem?

void CELinkConfiguratorView::OnOnline()
{
// TODO: Add your command handler code here
CELinkConfiguratorDoc* pDoc = GetDocument();
// Open the serial port

if(pDoc->ComportInfo.ubComInterface == 0)
{
CString msg;
if(!m_Port.Open(ComportNur,
ComportBr, Parity,DataBits,StopBits))
{
msg.Format ("*** Error: Can't open com port");
AfxMessageBox(msg);
return;
}

}

CBrowseOnline DlgBrowse;
DlgBrowse.m_BrowseStr = "Start Browse NetWork...";
if(DlgBrowse.DoModal() == IDOK)
{
isCanSendNew = true;
DownDirect = RST_REQ;
}
}

BOOL CBrowseOnline::OnInitDialog()
{
CDialog::OnInitDialog();
// Inial the progress bar
m_ProCheckOnline.SetRange (0, 63);
m_ProCheckOnline.SetStep (1);
m_ProCheckOnline.SetPos (0);

// start timer
SetTimer(1,100,NULL);
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

void CBrowseOnline::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if(CurrentCtrl == 3) // upload command
{
if(CurrentMacid == 0)
{
str.Format ("Uploading module setting...");
}
else if(CurrentMacid < 63)
str.Format ("Upload Node %d from Scanner",CurrentMacid);
else
str.Format ("Upload completed.");
}
UpdateData(FALSE);

What if you changed the OnOnline() method to:

void CELinkConfiguratorView::OnOnline() 
{
    CBrowseOnline DlgBrowse;
    DlgBrowse.m_BrowseStr = "Start Browse NetWork...";
    if(DlgBrowse.DoModal() == IDOK)
    {
        isCanSendNew = true;
        DownDirect = RST_REQ;
    }
}

Does the dialog appear now?

OnApply()

Hi
I have a propertypage.I have two edit controls.For the first edit control it should have a range of 5 to 50 and for the second it should be 60 to 100.Whenever the entered data was not in this range I gave an error message and set the focus using SetFocus().I have done this in the OnApply() also.
The problem is I have entered the data in the first control and even after receiving the error message and the focus was set also,I have neglected that and entered the data in the second control.For that also I did the same.Finally in the OnApply() also after neglecting the error messages , the dialog has closed.
My requirement is the focus should not go and it has to rise indefinitely if it is not in the range unless I click cancel.Is my approach correct?Please give me a solution.

Thanks in advance.

For starters, do not enable the OK or Apply buttons if either of the edit controls have invalid data. That alone will get rid of most, if not all, of your problems.

DeviceIoControl function error

Hi All,

i am calling DeviceIoControl function to Reset the shared drive device

code snippet is as follows
DWORD dwErrCode, dwErrCode1;
HANDLE hDrive = ::CreateFile("\\\\.\\PHYSICALDRIVE0", GENERIC_READ |
GENERIC_WRITE, FILE_SHARE_READ |
FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING, 0,
NULL );

//check the error in getting teh handle
if (hDrive == INVALID_HANDLE_VALUE)
{
dwErrCode = GetLastError();
return 0;
}
DWORD dwBytesReturned = 0;
STORAGE_BUS_RESET_REQUEST sbRR;
sbRR.PathId = 0;

BOOL bRet = DeviceIoControl
(hDrive,
IOCTL_STORAGE_RESET_BUS,
&sbRR, sizeof(IOCTL_STORAGE_RESET_BUS),
NULL, 0, &dwBytesReturned, NULL);

if(bRet == 0)
dwErrCode1 = GetLastError();

CloseHandle(hDrive);

I am working on windows 2003 server, same code works fine on windows 2000

GetLastError gives "Incorrect Function Error"

can anyone help on this,

Thanks,
Tushar.

I think the fourth parameter to DeviceIOControl() should be sizeof(sbRR).

Could it be that the driver you are trying to reset does not support the specified function?

But does the exact same driver run on both platforms? Chances are that it doesn't, and if that's the case, there could be a slight difference between the two. I'm just grasping at straws here, so my suggestions are somewhat limited.
