Hello,
I am facing problem with usage of CStdioFile::WriteString method.
The problem is as follows:

There is only 4 to 8 KB of disk space left in the target directory.
I have a CString variable containing about 12KB of data.
I open a ASCII file using CStdioFile as follows:

CFileException exception;
CStdioFile outputFile;
if (!outputFile.Open(m_strFilePath, CFile::modeCreate |
CFile::modeWrite | CFile::shareExclusive | CFile::typeText))
{
// handle error here
}

then attempt to write to the file as follows:
try
{
outputFile.WriteString(strValue);
}
catch (CFileException* fileException)
{
// handle error
}
catch(...)
{
// handle error
}

Then i close the file as follows:

try
{
outputFile.Close();
}
catch (CFileException* fileException)
{
// handle error
}
catch(...)
{
// handle error
}

Neither CStdioFile::WriteString not CFile::Close() throw any
exception.
I have read the MSDN documentation of CStdioFile::WriteString(). It
says that this method will throw a CFileException in case of disk
full.

Another strange thing i have observed is that if the disk space is
less than or equal to 4 KB then disk full CFileException is thrown.
But not by CStdioFile::WriteString() instead by CFile::Close() which
follows in my code above. That is presicely the reason why i have
outputFile.Close() inside try catch block.

Can some one help me please.

Thank you very much in advance.

Best Regards,
Syed Khadeer.
