I think a map is between one thing (key) and another thing (object). [*]

But you could package the name and regno in a structure together, then map between the id and otherstuffstruct...

Confusing... In MFC there is a map template class named CMap.

As suggest by Iain, you may use a struct, for instance, assuming id unique (see, for instance, [^]):

#include <map>
using namespace std;
struct MyData
{
  string _name;
  int _regNo;
  MyData(string name, int regNo): _name(name), _regNo(regNo){}
};

void main()
{
  map <int, MyData> mymap;
  mymap.insert(pair <int, MyData>(1, MyData("foo", 10)));
}

BTW MFC hai is own CMap container, but keep away from it!

Or this way too.

std::map<int,pair><string,int> > myMap;
myMap[10] = make_pair("cp",10);

Using STL's std::map from MFC is no different from using it anywhere else. See here[^] for an example.

Different encoding??

Sorry for my repeat post as my previous post crosses so many pages...

I'll explain my problem once again...

I've one database which includes chinese and english character... Now extracting from the database is done..with the help of connection object and query and all other thing..That's not the issue...

Now when i extract the part (Field) which contains both english and chinese character with the help of this..

_bstr_r  bstrString_Dest;
bstrString_Dest= m_cpRecordsetSearch->Fields->GetItem("DestinationValue")->GetValue().bstrVal;

Now when i see using quick watch or tool tip it comes "abc??????" question marks are actually chinese character...

Now i do this to write into the file...

stream = fopen(pszwritepath, "ab");
if(stream == NULL)
{
   return 0;
}

int n = fwprintf(stream, L"%ls\r\n", (wchar_t*)bstrString_Dest);

It comes to notepad as "abc(aquare brackets)"... Now when i copy the text from notepad and paste to MS-Word or MS-Access it shows perfectly.. i.e "abc(chinese character)"... But when i see same file on chinese machine it shows junk character...

So where am i going wrong?? Is there something encoding compatibility of notepad in my machine and chinese machine?? I'm really stuck in here...

VC++ is not good at showing you the chinese text. I assume the characters are not in the font it uses. This does not mean the code is bad.

Notepad is just guessing at the encoding, and getting it wrong.

But if you're saving UNICODE, you can help notepad by saving a byte order marker (or BOM) at the front of the file.

I forget it should be FFFE, or FEFF. But as that's only two choices, try both and see which works.

You possibly will also have the problem of fonts having the chinese characters in it in notepad.

Good luck,

Iain.

All right i get it...

stream = fopen(pszwritepath, "ab");
if(stream == NULL)
{
   return 0;
}

int n = fwprintf(stream, L"%ls\r\n", (wchar_t*)bstrString_Dest);

Above code is working perfectly... I wasn't selecting unicode while i was seeing in notepad (Silly mistake)... But as i've to make many file how do i make sure that the data which is being writed to notepad open as unicode only not ascii???

Thanks

P.S
Didn't saw ian's post.. Thanks i'll try to do that..
You mean to say before i write to the file i should write that byte order marker (BOM) first???

I have a following code for createing a thread. but it generate the error msg as:
error C2665: 'AfxBeginThread' : none of the 2 overloads could convert all the argument types

CWinThread* mpWinThread;
mpWinThread = AfxBeginThread(&CDataCapture::ThreadProc,NULL,0,0,NULL);

and ThreadProc function is as follow:

UINT ThreadProc(LPVOID pParam)
{
return 0;
}

I am not getting where is the actual problem.

Thanks,

Hello Abhijit,

As per your code snippet, ThreadProc is a global function and not the member of CDataCapture. Change the code snippet like this.

CWinThread* mpWinThread;
mpWinThread = AfxBeginThread(ThreadProc,NULL,0,0,NULL);

Regards,
Jijo.

It seems that the ThreadProc function is a member function of a class. You can't do that unless the function is static.

I didn't think you could...

But I know the function to read from this is GetPrivateProfileString / Int, so while looking for that function in msn, I stumble across:

MSDN wrote:

The GetPrivateProfileSection function retrieves all the keys and values for the specified section of an initialization file.

Also, GetPrivateProfileSectionNames.

I hope that helps!

You possibly need
