Hello,
Does anybody know if it is programmaticaly possible to change the default codepage of the system. Or even better if the default codepage an application uses can be altered. So that during the run of the program conversions can happen through usage of codepage x, where x can take several values during the lifetime of the program...
I need that to make sure that assignment of multibyte characters to CString objects are converted correctly and swprintf statements also convert parameters that are multibyte strings, to the correct equivalent in unicode..
If anybody knows a way, please let me know....
Greetings,
Davy..

Use MultiByteToWideChar directly. You shouldn't be changing the user's locale settings without their permission. As I recall, changing the system default locale requires a reboot anyway.

Thanks for the reply 
However, in my situation it is so that the program is allready written, and suddenly 'they' came up with the tremendous idea that it should have that ability  . So, I do not want to find every instance where I convert multibyte strings to unicode or vice versa using CString assignments, CString constructors, CString Format calls, sprintf wsprintf mbstowcs wcstombs and what other conversion calls there might exist  (program written by multiple programmers so everybody has his/her favorite conversion-method).
About changing the locale of the user without his\her permission is luckily not an issue here, because this app is supposed to run within the company on only some specific PC`s which will only run this app, so I guess the app has the right to do it.
Reboot is also not a problem because if that^s all that^s needed for the data to be displayed correct it is a small price, the codepage will not need to be changed every 5 minutes or so, more about every 5 days...
Anyway, a process-wide default-codepage would offcourse be the best solution, but I don^t think that^s how it works.
So if anybody knows a way to achieve my goal without having to search for every place where a char string was converted to wchar string or other way around. Please let me know...
Greetings,
Davy

Aha!
SetThreadLocale looks like it does what you want.

hi
i have developed a server socket program which keeps on sending message. i have created a seperate thread using afxbeginthread(SendMsg,this) (this points to the CSocket derived class). im using carchive. the problem is when the thread tries to send messaage i get a debug assertion error.
i dont know what is the cause of the problem.
UINT SendMS(LPVOID lp)
{
CServerSock* pSock=(CServerSock*)lp;
do
{
pSock->SendStatus();// here i get error
Sleep(1000);
}while(pSock->m_pDlg->m_sta);
return 1;
}
void CServerSock::SendStatus()
{
m_pDlg->Serialize(*m_pArOut);
m_pArOut->Flush();
}
when i press retry i goes to base class
void CAsyncSocket::AssertValid() const
{
CObject::AssertValid();
ASSERT(m_hSocket == INVALID_SOCKET || CAsyncSocket::FromHandle(m_hSocket) != NULL);
}
outside the thread im able to send the message. i would be happy if u can help me with this problem
regards
aswin

Dear u can not use CSocket in the worker thread .If u want to use CSockets with threads then use User interface threads.
But there are so many problems when u even use it in User Inteface threads.
What u should do Accept the sockets in the context of one thread(may be primary thread) , then Detach the socket handle from the CSocket Object Then start the Thread in suspneded mode ,Save it to Class level object of your CWinThread derived class.
Then resume thread .And attatch the Socket handle to Class level object of CWinThread derived class. may be in the Ininstance .
Now your socket object will be valid in the context of new thread.
Note:
You should also called AfxSocketInit Initinstance of your CWiThred Derived class.
if u dont follow these steps , may be your program work fine in debug mode , but it will get crashed in release mode.
No Worries!

Hi there
How can i create a CRgn from String?
Thanks for reading
|
|
|

One way I can think of is:
0) CDC::SelectObject (your font, perhaps)
1) CDC::BeginPath ()
2) CDC::TextOut (your string here)
3) CDC::EndPath ()
4) ::PathToRegion ()
Tada!
Don't forget to tidy up your CDC by removing any selected fonts, etc.

You will needed to create a DIB section and routines to read and write the pixels directly. The book "Programming Windows" contains code for doing this (no trig. required). Alternatly, on windows 2000 and above you can use world transforms (a bit tricky).

2) I saw SpyXX.exe Loading a library remotely (loading spyhook55.dll under winamp.exe, for instance). How can I do that?

Hi folks!
I want to program a tool that only stays as a tray-icon.
My problem is how to design it in MFC.
The application is a CWinApp, but without a Window in m_pMainWnd it closes immediately.
How do I build an application that runs without a window?
Do I need a valid hwnd for Shell_NotifyIcon()? (I tryed with NULL as hwnd and it seemed to work..)
One solution may be to create a window but never show it. But perhaps there is a better way out there... 
Thanks!

You could actually search this site...
One of the very first articles here was a Tray icon application by Chris Maunder.
Just search for tray icon etc.

I am writting a C/S program based by Socket and IO completion.
I use CreateIoCompletionPort and GetQueuedCompletionStatus to build and get the connected socket. The Server program goes well when it is built.
I also built a client for testing server.But a problem comes.
If I use one client to connect the server, everything is fine.
IF I use two more client to connect the server at the same time, the server handle them one by one.It doesn't handle them synchronously as I expected.
Does anyone know the reason. Anyone is so kind to replay me?
Thanks.

u gave the answer in ur question!!
read it carefully U will get the key!!
The chosen One
|
|
|
|
|
Really?
Sorry, i have tried a lot. But it isn't improved.
I am locked by the it.
Can u tell the detail of the key ?
|
|
|
|
|
hmm, unless you have 2+ CPU box, it will handle them always synchronously. IOCP only can help somehow masquerade it.
Checklist for the very beginning
- are your sockets initialized as OVERLAPPED?
- are there more threads waiting in GetQueuetCompletionStatus?
- what about the return codes from WSASend/FileWrite, are they correct?
- is the problem while accepting the clients, or while communicating?

My xml file is below:
<?xml version="1.0" encoding="GB2312"?>

</city>
<city>
<cityname>yaan</cityname>
<point>(346,335)</point>
</city>
</list>
</root>
There will be many cities in xml file,and I want to get city name,point of a city at a time and store them into a struct,then I use selectNodes("list"),but it return a NULL pointer, thus I consider that the only list node is the reason,so I use selectSingleNode("list"),but it also cannot work and return NULL pointer,I've no idea,hope your help
I love Aquamarine.
