Hi All,
a) Is there a direct way of finding a string in a file,
instead of using ff.seek or ff.getposition?
These methods need addressing in terms of bytes,
which may vary unpredictably.
Should one execute ff.ReadString( strLine )
as many times as necessary to check if strLine matches
the searched string?
string strLine, strSearchedStr;
int ii, n;
for (ii = 1; ii < n; ii++)
{
ff.ReadString( strLine );
if ( strSearchedStr == strLine )
break;
}
b) How can we control a loop by means of the end of the file?
Is there some kind of EOF (End Of File) constant?
Would the following code work?
stdioFile ff;
LONG lPosition;
string strLine, strFile;
if ( ff.Open(strFile, file::modeRead) )
{
ff.SeekToBegin();
DWORD dwLen = ff.GetLength();
do
{
lPosition = ff.GetPosition();
ff.ReadString( strLine );
...
}
while ( lPosition < dwLen )
}
Thanks in advance,
