Is the ini file mixed with ANSI and UNICODE?
Then, if UNICODE means UTF-8, it may be solved by MultiByteToWideChar and WideCharToMultiByte, I think.
When UNICODE means UTF-16, I dont have any good idea, sorry.

If the ini file is all UTF-16 encoding with BOM, GetPrivateProfileStringW and WritePrivateProfileStringW could not help you?

Yes the Ini file is the mixture of ANSI and UNICODE.
The file format is also in the UTF-8.

How the MultiByteWideChar will help, is this is th way?

1.Use GetPrivatePrfileString.
2.Convert the buffer using WideCharToMultiByte.

char szUtf8[LINE_SIZE];
int n = GetPrivatePrivateStringA("section", "key", "", szUtf8, LINE_SIZE, "inifile.ini");
DWORD flags = 0; // some conversion option here
int n2 = MultiByteToWideChar(CP_UTF8, flags, szUtf8, -1, NULL, 0);
// ...allocate buffer
MultiByteToWideChar(CP_UTF8, flags, szUtf8, -1, pUtf16, n2);

Above code can work? (I did not check this with real code yet) Good luck Smile | :)

You can show a cut/paste menu reacting to the OnMouseDown event. The message handler has a parameter "short Button" =1 for Left button =2 for right button. You can get the range of selected cells with GetCol() GetRow() GetCellSel() GetRowSel() The two first gives you a corner of selected cells and the two last gives you the opposite corner. You only need to call GetTextMatrix in order to obtain the cell's text and store them in some structure or array or the clipboard. To paste you only have to follow the inverse procedure. I hope this can help you

Where exactly is the file you're trying to write to? Do you have privileges to write to the file?

If you understand the metadata area of a file($MFT area)of a particular file , that is the location where I have to modify some values of a OS drive. But windows is not giving me permission to write at low level.

Hi,
Please have a look
std::vector<cstring> Names;
ENUMLOGFONTEX *lpelfe;
Names.push_back(lpelfe->elfFullName);

the above lines gives an error like....
error C2440: 'initializing' : cannot convert from 'BYTE [64]' to 'ATL::CStringT<BaseType,StringTraits>'with[BaseType=char, StringTraits=StrTraitMFC_DLL<char>] ]

and please try to help regarding the same...

What type of data do you want to push to std::vector?
If you want CString, try

std::vector<CString*> Names;
Names.push_back(new CString(lpelfe->elfFullName));

or you do with BYTE[], try

std::vector<BYTE*> Names;
BYTE* aName = new BYTE[sizeof(lpelfe->elfFullName)];
memcpy(aName, lpelfe->elfFullName, sizeof(lpelfe->elfFullName);
Names.push_back(aName);

Do not forget delete elements after you dont need vector both above.

I think , first Option should work.
Bcoz while creating CString from Byte , you should say new() to it..

It's not enough to be the best, when you have capability to be great...

Try a two step approach.

ENUMLOGFONTEX *lpelfe;
CString str = lpelfe->elfFullName;
Names.push_back(str);

Can't you just use CString if you are already using MFC? Why do you have to use the std containers?!

Getting File Data without opening the File

How do I get Time Info on a remote network file of the Last Write on a File without actually opening the file. I have an App that needs to know when to re-load. It Opens the File every three minutes to check the last Write time,to determine if it's own version is stale. That traffic alone causes problems. Windows Explorer seems to have a way of getting this info in that way.
