As I already suggested, MFC object serialization, is far better for the purpose.

The following code snippet create two keys under the section 'General' of the File 'MyFile.ini', and then reads one of the keys, showing the value in a message box.
(of course error check is left to the reader...)
Please note 1: if the file doesn't exist, it creates both the file and the section.
Please note 2: I used WritePrivateProfileString and GetPrivateProfileString, otherwise the I/O would happen inside the registry.
const CString szINIFILE = _T("C:\\Documents and Settings\\anu\\beginning\\MyFile.ini");
CString szFirstName;
WritePrivateProfileString(_T("General"),_T("FirstName"), _T("Anu"), szINIFILE);
WritePrivateProfileString(_T("General"),_T("LastName"), _T("???"), szINIFILE);
GetPrivateProfileString(_T("General"), _T("FirstName"), _T(""), szFirstName.GetBuffer(MAX_PATH), MAX_PATH, szINIFILE);
szFirstName.ReleaseBuffer();
AfxMessageBox(szFirstName);

Thanks....
this works....
but i put the same lines of code in my MFC
application....
still it works....
can u explain how?
WriteProfileString...... is a console function...
then how come it work with MFC?
|

WritePrivateProfileString is just a WIN32 API's function: Console applications, as well as GUI (and MFC) ones can profitably call it.

I would like to know how to configure the ip address of a notebook PC. I only want to configure the wireless network adaptor how can I identity it if I don't know the name of the wireless network adaptor.
Also, how to configure the adhoc mode in the notebook by Visual C++?
Please help!!!
|

1/ I doubt it's any different on a notebook to a normal one, other than needing changed more often.
2/ I had the same problem a while ago, as I was forever changing my IP address, so I wrote a little tray app to do it. Quick and dirty, but it worked.
I gave up trying to change it programmatically, and ended up using the
netsh interface ip set command instead, and CreateProcess to make sure that no dos prompt flashed up.
3/ I know nothing about adhoc wifi! Would be nice to learn some time...

In the notebook PC, there are more than one network interface. How can I identify the wireless one from another? I know that we can change it with registry if we know the right one.
I can find the adhoc wifi setting in the registry. Can anyone give some hint of it??
Please help!

i want change the font size for existing createfont() handle without creating again.
Is it possible?
|
|
|
|
|
The answer looks no, or too complex to be the right way.
Why you doesn't like a solution like thi one?
LOGFONT LogFont;
m_Font.GetLogFont(&LogFont);
LogFont.lfEscapement=900;
m_FontVert.CreateFontIndirect(&LogFont);
in my code I'm rotating the font to have vertical text, but you can do the same on the same CFont variable to change other parameters as the font size.

I have created this socket xample application given in learn vc++ in 21 days which is successfully working. now my question is how do i connect to multiple ip addresses in my applicaion.
right now this is what is does
m_sConnectSocket.Connect("25.25.25.25", m_iPort);
this ic working. but i want to add multiple ipaddress.
Thanks in advance.

What do you mean exactly by multiple addresses ? Why can't you simply open several socket connections if you need ?
|
|
|
|
|
multiple address means multiple people. tried to open several connections. if i give 2 or more connections none of the connections are successful
|
|
|
|
|
But what about using multiple sockets instead of one ? How many connections do you need to open ?
|
|
|
|
|
i have not ventured much of socket programming.. so i dont know much about it.. infact i can tell u that it was the first application that i am trying in socket programming. well, when i am trying with one connection it is working. but if i am using multiple connections it is not. i want something like if i send a message then it should reach multiple people.. if multiple sockets can be used then i needs some leads for that.

Why can't you simply use several different CSocket class instances ? What you did for your example, just do it again with another CSocket instance.
You still didn't answer: how many connections do you need to establish ?
|
|
|
|
|
ok. sorry for that.. right now i want to make 3 connections.
i shall certainly try doing it with ur leads. will get back to you soon..

Do you need multicast socket??
Look here[^] for example
I hope it helps..

Hi all,
I have a stringstream, and I want to find the index of '<' sign contain in the stream. Actually first content.
<br />
stringstream str("y:<?xml version=\"1.0\" encoding=\"UTF-8\"?><Statistic>");<br />
<br />
int offset = str.str().find('<', 0);<br />
Then I want to remove all the content up to '<' sign and need to make a stream like this.
<?xml version=\"1.0\" encoding=\"UTF-8\"?><Statistic>
Can you help me to do this.
I appreciate your help all the time...

Extract the required part by substr() and update streambuffer. Have a look at code snippet.
stringstream str("y:<statistic>");
int offset = str.str().find('<', 0);
str.str( str.str().substr( offset ));
</statistic>
Regards,
Jijo.

Ok, thanks.
But how about this way?
str.str().substr(offset)
I appreciate your help all the time...

str.str() is not returning reference to string. This statement will return back a temporary string object. Hence, It won't update the string stream buffer. For instance,
string temp = str.str().substr(offset);

Jijo.
