My bad. I read your earlier post as "You can not read..." which is why I was providing an example that showed otherwise. I'll need to not be so quick with my trigger finger! Blush | :O

Hi,
MCI (Media Control Interface) is part of Windows SDK. You may
need to work with low-level MCI if you have to directly manipulate
raw audio-data. I am not sure if MCI supports MP3 files directly,
though.

TCP Clients management

I need to check the IP address of all clients connecting to my server application.
Ive used the following code to accept client connection and to obtain its IP Address:
SOCKADDR l_ClientAddress;
m_pListeningSocket->Accept(l_TempSocket, &l_ClientAddress, &l_iClientAddressSize)

When I execute this code, I've problems to check to l_ClientAddress variable content: the sa_family field contains the number 2, but the sa_data field contains stange charactes....
How can I manage this variable ? I need to compare the client address with a string in the form xxx.xxx.xxx.xxx.....

Thank u very much !!!

Do the following:

<br />
SOCKADDR_IN addr_in = *(SOCKADDR_IN*)&l_ClientAddress;<br />
char *pIPAddress = inet_ntoa(addr_in.sin_addr);<br />

And what do you think it should contain? As I understand it, that is an "input" member rather than an "output" member.

: How to send message to base dialog window from tab page

Dear All,

I am developing a dialog based application using MFC VC++ Version 6.0 for Windows 2000. The application consists of a TabControl derived from CTabCtrl Class having three tab pages in it. Also, the tabControl has Apply, Cancel , Ok button.

My query is how to disable "Apply" button on the click of an event on tab pages, i.e if on changing a selection of a given radio button in a tab page, the Apply button should become disabled.

Similiar case, like "Display properties" dialog box which appears upon right clicking on the desktop. When we select a background and click on apply or ok button to make the changes, the background color gets changed.

Please feel free to ask further clarifications in this regards,

Regards,

rajesh

extern int tmpchkflag;

((CGeneralSettings*)m_tabMyTabCtrl.m_tabPages[0])->getSettings();

if(tmpchkflag) {
int iReturn = MessageBox("You must restart your computer before new settings will take effect.\nClose all applications and click OK to restart your computer.","EZ HDD Standard: Settings Change",MB_OK|MB_ICONQUESTION);

if (iReturn == IDOK) {
GivePrivilege();
if(!ExitWindowsEx(EWX_REBOOT| EWX_FORCE ,0)) {

if(dlg.DoModal() == IDCANCEL)
CDialog::OnCancel();

In the Window Procedure, do the following:

<br />
case WM_NCACTIVATE:<br />
  return DefWindowProc(hWnd, message, (WPARAM)0, lParam);<br />
<br />
case WM_CREATE:<br />
SetWindowPos(hWnd, HWND_TOPMOST, 0,0,0,0, SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE);<br />

Note: the first time the window is displayed, you would need to take away focus from it. after that, it should work as u need.

Thanks for the info!

I tried to use it, but it does not seem to work. Also, when i try and drag the window around, its "jumpy" - like when your CPU utilization is very high and you're trying to move a window...

Any idea about how to fix this problem?
