Have you tried:

David, Thanks for response. I found the problem. This C++ Exe is used to call my .net web service from client machine. So it was quite difficult to debug. But finally I have found the problem, it was with some return value. and solved . 
Again thanks.
cheers,

CString defined lots of constructors such as CString(LPCWSTR lpsz) & CString(LPCWSTR lpch, int nLength);
CString ver;
wchar_t* ver2;
...
CString ver3(ver2);
if(ver==ver3){
...
}else{
...
}

You should ask a bit more precisely...give some more details about what you want to do.

Are you referring to the LVS_OWNERDRAWFIXED style?

Hi all,
my requirement is there is a function which creates one thread and passes the data for further processing which looks like
void MyFunc(char *data)
{
CreateThread(NULL,0,build_data,(void *)data,0,NULL);
}
Now i want to modify the above code.
I want to introduce a queue class and want to create two threads so that 1st thread can invoke a function which writes the data to the queue and the 2nd thread reads the data from the queue. Please introduce mutex if required. Can you tell me how to implement the above in VC++.
Please help me on the above. Thanks

This sounds a bit like the producer/consumer problem.

Hi there.
I am writing a string into a .txt file, but I am getting an extra while space in between each char.
Please suggest me, why this is so.
For Eg. if I write Hello, it will be written as H e l l o.
Thanks

I'm going to put on my psychic hat...
You are not getting a space between letters, you are getting a NULL.
Your text in the compiler is a TCHAR, and that defaults to unicode these days.
You're looking at the text in notepad, and it's reading it as ascii...

If your're passing string something like this, _T("Hai"), according to the unicode settings of project, the string will be treated as unicode characters which means two bytes per character. That's the reason for this issue.
CFile::Write will take any kind of inputs. If you've the string with you,
you can writes as file1.Write( "Hai", 3 ); or convert using WideCharToMultibyte API or W2A conversion macros and then write the file.
If you want to write and save the file as unicode text file, then you will have to add BOM characters before writing to file.

Hello,
ask to help me with 2 problems.
Access-database has password and open by
try
{
hr = m_pConnection->Open(_bstr_t (lpstrConnection), ...);
return hr == S_OK;
}
catch(_com_error &e)
{}
1) When database file has attribute "ReadOnly" catch takes place with NativeError=0xfffff88f and NumberError=80004005 ("Not a valid password").
But when ja reset attribute "ReadOnly", database is opened OK. Why error is detected for Readonly file?
2) How can I recognize that invalid password is in connection string? Which code will be in NativeError for any database type (not only Access)in this case?
Thanks

Is it readonly at the OS level or at the application (i.e., Access) level?

Hi to everyone,
I am breaking my head to find a proper example how to use map of STL in mfc. But didnt get.
Could anyone please help me out with the same. Please give me the exact syntax to use them.
I want to create a map with 3 fields (like a table)
id, name, RegNo
thanks in advance
I am a beginner

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.

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.
