I am using the following code as shown similar.

<br />
wchat_t pExeFile[128];<br />
wchar_t pModuleFile[512];<br />
wsprintf(pExeFile,(LPCWSTR)"%s",pModuleFile<br />

if I use char instead of wchat_t it shows error the following error
"error C2664: 'wsprintfW' : cannot convert parameter 1 from 'char [128]' to 'LPWSTR'"

Thanks and regards,

OK, so you do know where to look, but you haven't ?

Basically, your window gets WM_COMMAND and the lParam and wParam can be used to find the control that generated it.

Hope I understood your question
You Create a button

m_MyButton.Create("Button",WS_CHILD|WS_VISIBLE,CRect(0,0,100,23),this,IDC_MYBUTTON);

Now you need to events for this button

#Define IDC_MYBUTTON 20000

BEGIN_MESSAGE_MAP(CMyAnswer, CDialog)
ON_BN_CLICKED(IDC_MYBUTTON, OnBnClickedMyButton)
END_MESSAGE_MAP()
...
...
void CMyAnswer::OnBnClickedMyButton()
{
MessageBox("Test");
}
////////And in header file insert
afx_msg void OnBnClickedMyButton();
Is your purpose?

I can't speak for MFC itself, but the way I've done this before is:

Create a new UDP socket.
Call 'connect' with a non-local IP (I've used google.com's IP but any will do)
Call 'getsockname' on the socket to get the local address.
Close the socket

Note that no data is ever sent on the network - this approach uses the fact that connect()ing a UDP socket doesn't do anything but bind the socket addresss. A side effect of this is that the local address (as returned by getsockname) is set to the outbound IP address of the machine. Or rather, the IP address that is used to tgalk to the non-local IP you specified.

Unfortunately, if you're behind a NAT (as most people are these days) getting the real external IP is somewhat different. I believe you can use UPNP (if your router supports it) but the only way I'm aware of is to actually connect to and exchange data with an external server who can then tell you which IP address you're coming from. This relies on you having a server running somewhere...which is a bit beyond your original question.

I hope that's at least of some help!

Hi,
Can anyone tell me what exactly the

#if _MSC_VER >= 1100 will do. what does the value signify? what are the other possible values??.
Where can i find any documentation on the above. I could'nt find it in google, MSDN.

Thanks & Regards,

_MSC_VER is the version of Visual c++. 1100 is VC5, I believe. Either way, it's used to write code which can target multiple VC++ versions, where the versions differ.

Its compiler version.
From MSDN:-
_MSC_VER Defines the compiler version. Defined as 1200 for Microsoft Visual C++ 6.0. Always defined.

It says that

If Microsoft Compiler Version is Greater than or equal to 1100 compile the statements that is wrapped in side the block, else don't compile. It's a conditional compilation statement.

Listing files in a directory

I want to list all the files in a certain directory which were created "after" certain date. I've thousands of ever growing files in that directory. If i enumerate these files using FindFirstFile method and then sort these on the basis of date, it take enormous amount of time.
Can anyone tell me better technique to do so. Is it possible with MS-DOS 'dir' command. If yes, then how and also how can i execute that dos command programatically ?

You can use DlgDirListthat fill listbox with files/folders and also you can use attributes of files/folders.if you want to use this function you can see two examples on MSDN. Smile | :)

Rather than add them all to some data structure, sort the data structure, and then process the ones at the top (or bottom) of the data structure, just check the date as you are enumerating the files. Something like:

FindFirstFile(...);
while (...)
{
    if (file_create_date < cutoff_date)
        add_to_list();
    FindNextFile(...);
}

Now the list will only contain those files that were created after a certain date.

Use of SetSysColors with COLOR_ACTIVECAPTION, would be one solution. But it applies to all windows.
