sometimes, the compiler sends strange errors. when it is the case, i rebuild all the project (delete all the .o and the .exe, then recompile all + link).
but if you have an exception, it means that the error occurs at run time...
can you anyway give us the description of that exception (text, error number, things that can actually help us) ???

I pasted my assignment on the bottom of my post. Basically I know a little bit on how to program but I dont know how to work with the IP addresses as variables. I have the algorithm but i just don't know how I can put it into form. If someone can please help me out with that, i'll really appreciate it. Another thing is I dont know how to do BINARY AND with the input IP address and the subnet mask. It's a really short program.
::Algorithm::
Router forwarding algorithm:
Extract netid from datagram's destination IP address
If (netid is for a directly connected network)
deliver it
Else if (table contains a next hop for netid)
send datagram to next hop
Else if (table contains a default route)
send datagram to default router
Else
error
::::Instructions:::
Write a program that simulates a 5 interface IP router using CIDR addressing.
To simplify the program, assume traffic flows in one direction only - all
traffic will enter port A and will be routed to ports B, C, D or E.
The program should prompt the user to enter an IP address in dotted decimal
notation. Your program should then consult the routing table and display the
input IP address, the next hop IP address in dotted decimal notation, and the
output port. Your program should continue in this manner until the user
decides to quit.
Routing Table
Destination Next Hop Port
128.6.30.0/24 192.200.5.11 B
33.33.32.0/24 192.150.7.21 C
40.33.101.0/24 192.180.45.3 E
50.60.70.0/24 135.200.2.11 D
45.45.4.0/24 192.200.5.11 B
150.7.200.0/22 192.200.5.11 B
130.3.4.0/22 135.200.2.11 D
250.123.192.0/20 192.180.45.3 E
128.235.0.0/16 192.200.5.11 B
30.0.0.0/8 192.150.7.21 C
0.0.0.0/0 192.150.7.21 C
Design Requirements
Your program must convert the input IP address to binary and AND it with the
masks in the routing table. Any other approach will result in points being
taken off.
The information in the routing table should be hard-coded into your program.
You may use any convenient format to represent the information .
There are no specific requirements on the user interface - either a console
application or a graphical interface is acceptable.
I prefer that you use the C, C++, or Java language, but you may propose using
another. You may use any compiler/development environment as long as I am
able to run your program on a PC running Windows XP.

You can either use strings, or create your own class to contain an IP address.

what about the binary part? Can anyone simplify how a routing table works, I've been searching all day for a simple instruction on how they work but I get complicated instructions.
Thanks

It May not be the right place to post this question but i think some one can clear things up for me it's concerning mobile apps
- Is it possible to add new fonts for use in sms messages
- how about supporting a large number of characters
- what programming language is used to develop the new font
- or is there a tool kit for doin such kind of stuff
- will the developed font on all mobile equipments
- is it dependent on the os of the mobile
- are there any good web sites concerning these questions ?
- is there some one who is familiar with the large number of chracters that would be supported like a chinese language or so?

Hi folks,
This is probably a very basic question, but I can't figure out a good answer.
I have CFormView-derived class that I display as an MDI child in my app. This works fine. However, under a specific circumstance, I need to display the same form from within a modal dialog, as a modal dialog, so that I can modify the data in the parent dialog after the child terminates.
I can, of course, duplicate the code and create a new dialog to do this. But I am hoping there may be a way I can use the same code as in the form view so that I do not have to maintain two sets of code for the same screen.
Can anyone point me to a way to do this? Or the other way round? That is, have the code in a modal dialog, but access it from a form view?
BTW, I am still
Thank you for your time.

You'll have to create a new class derived from CDialog. You can of course re-use the dialog resource (IDD_FOO).

Hello.

i was able to add the icon to the systray, but when i move the mouse
over the icon, it disapear.
anyone knows why?

Can we assume you called Shell_NotifyIcon() and are being notified correctly? Have you seen these other examples:
http://www.codeproject.com/shell/StealthDialog.asp
http://www.codeproject.com/shell/ctrayiconposition.asp
http://www.codeproject.com/shell/minimizetotray.asp
http://www.codeproject.com/shell/YaTrayMin.asp

Thanks, i'll try these examples (i've tried some of them).
anyhow, i used 'Shell_NotifyIcon()' to get the icon into the systray.
but, i did not recevied notifications!
Code i'm using:
******************************
#define WM_uSYSTRAY_ICON (WM_USER+20)
#define uSYSTRAY_ICON_ID (WM_USER+21)
...
...
m_NID.cbSize = sizeof(NOTIFYICONDATA);
strcpy(m_NID.szTip, "SysTray icon");
m_NID.uCallbackMessage = WM_uSYSTRAY_ICON;
m_NID.hWnd = this->m_hWnd;//this is a MFC created dialog ': public CDialog'
m_NID.uID = uSYSTRAY_ICON_ID;
m_NID.hIcon = (HICON)AfxGetApp()->LoadIcon(IDR_MAINFRAME);
m_NID.uFlags = NIF_TIP | NIF_ICON | NIF_MESSAGE;
Shell_NotifyIcon(NIM_ADD, &m_NID);
****************** end of code
any ideas?

I have been trying to get a dialog window displayed big and then small, but the SetWindowPos seems to do nothing since I added resize code.
I have a divider to control the clipping of the lower section of the dialog. See code below (Called via push button to hide/show details)
void CEditDlg::OnBnClickedAdvanced()
{
static bool m_bExpand = false;
if (rcLarge.IsRectNull())
{
GetWindowRect(rcLarge);
CWnd* pWndDivider = GetDlgItem (IDC_DIVIDER);
pWndDivider->GetWindowRect (rcDivider);
rcSmall = rcLarge;
rcSmall.bottom = rcDivider.top;
InitResizerLarge();
}
if(m_bExpand)
{
SetWindowPos(NULL, 0, 0, rcLarge.Width(), rcLarge.Height(), SWP_NOMOVE | SWP_NOZORDER);
m_origSize = CPoint(rcLarge.Width(), rcLarge.Height());
m_bExpand = false;
m_cAdvancedButton.SetWindowText("Hide Details");
}
else
{
SetWindowPos(NULL, 0, 0, rcSmall.Width(), rcSmall.Height(), SWP_NOMOVE | SWP_NOZORDER);
m_origSize = CPoint(rcSmall.Width(), rcSmall.Height());
m_bExpand = true;
m_cAdvancedButton.SetWindowText("More Details");
}
}
ANy way to get this code to toggle between big/small dialog; i.e. clip the window at the divider.

i need pc to link to cash regsiter so i can use my normal pos on cash regsiter -uniwell
point of sale systems

i think you can control the cash register via the Serial port, you just write the command to the port, that will take care of remaining...
Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

is there a way to programatically set the default playback and capture devices?
i.e. the device oyu select in control panel/sounds and audio devices/Audio: Sound Playback|Sound Recording|.. - Default Device
?
TIA

Already doing this - but I still want to modify the default devices..
Reason: We are sending the playback to an external device, and a message box plonk arriving there might blow away some ears.
The PC is set up for this purpose, but we would like to (a) set sound playback for our application to a specific device and (b) verify that default playback isn't there.

What about providing string resources, which may cover what ever language you want?
