CFile write unicode text in wince

Hello everybody

I'm trying to write some texts into html file using CFile::Write function. Below is what I'm using.

mFile.Write(myString,myString.GetLength() * sizeof(TCHAR));

As a result in the file however I get something like this:
0 1 : 2 2 : 0 6 . 0 0 T a e o t u i e o e

This should be written as:
01:22:06.00 Trace output file open

Any idea what the problem could be?

Thanks in advance!

Hi,

You are writing the file as unicode, but when you view it are opening it as ascii (one byte per character.)

Since it's HTML, you probably want to write it as UTF8, and can use WideCharToMultiByte to convert to that. Use google to find a suitable sample.

Just to make sure, you meant MultiByteToWideChar conversion, correct?

Hi,

In fact, I did mean WideCharToMultiByte. It sounds wrong, but WideChar is 16bit, MultiByte is 8bit.

Alan

Thanks for the replies Alan

So I modified the codes as follows, but I'm still getting the same result


char StringToWrite[500];

WideCharToMultiByte(CP_ACP,NULL,myString,-1,StringToWrite,sizeof(StringToWrite),NULL,NULL);

mFile.Write(StringToWrite,StringToWrite.GetLength() * sizeof(TCHAR));

Any ideas?

Hi,

This looks wrong: StringToWrite.GetLength(), did you show your exact code after changing it?

Alan

Yes the write function was called through another function which gets (CString myString) as argument. When I passed char[] type, it worked without complaining.

I managed to write the text part now correctly.
Now, I still have the timestamp part wrong. What could be the problem?

I'm doing the following for the time:

CString m_Hour,m_Min,m_Sec;
CTime currentTime = CTime::GetCurrentTime();

m_Hour.Format(_T("%02d"), currentTime.GetHour());
m_Min.Format(_T("%02d"), currentTime.GetMinute());
m_Sec.Format(_T("%02d"), currentTime.GetSecond());
m_Ms = "00";

// Formatting stuff
CString timeString ;

// hour
if (m_ShowHour)
{
timeString += m_Hour;
}

// min
if (m_ShowMin)
{
if (m_ShowHour)
{
timeString += ":";
}
timeString += m_Min;
}

// sec
if (m_ShowSec)
{
if (m_ShowMin || m_ShowHour)
{
timeString += ":";
}
timeString += m_Sec;
}

// ms
if (m_ShowMs)
{
if (m_ShowSec || m_ShowMin || m_ShowHour)
{
timeString += ".";
}
timeString += m_Ms;
}


// Now the write to file part

mFile.Write(timeString ,timeString.GetLength() * sizeof(TCHAR));

Well, it's still the same problem, you are writing it out with 2bytes per character, you need to convert to UTF8.
