Hi Hamishd,

Do you have newlines in the file? The ReadString() function only reads up
until the next newline. It also has a line length of something like 128
characters if I remember correctly. If you have that class you could try
upping that line limit, recompiling, and seeing if that fixes it. Or, if
you have newlines in the "line" you will have to use a normal CFile and
parse the lines yourself. CStdioFile and CStdioFileEx don't really know
anything about double quotes.

I have the following 4 lines of data in a text file which I want to
read (note the large number of spaces in line2):
..5,-90,50
"��
��
",0,50
-15630,166,205,0
0,0

CStdioFileEx file; CString str;
CString Data[10];

file.Open(_T("c:\\file.txt"), CFile::modeRead){
while(file.ReadString(str)){
Data[i++] = str;
}
file.Close();
}

But it doesn't read the 2nd line correctly... here's the result
Data[0] = .5,-90,50
Data[1] = "��
��
"
Data[2] = 0
Data[3] = -15630,166,205,0
Data[4] = 0,0

It should be:
Data[0] = .5,-90,50
Data[1] = "��
��
",0,50
Data[2] = -15630,166,205,0
Data[3] = 0,0

Hi Asm,

I think OP would have had similar problems with either in this case.
Perhaps OP started with CStdioFile and then tried the Ex version when they
couldn't get the original to work, etc. That's the problem with the "trial
and error" method. Until you get "trial and success" it's not all that
useful.

I pity the fool that uses this one ... :o)

Seriously, I need to get the code cleaned up and get it over to Joe so we
can have a place to direct people. This topic is coming up far too often.
I'll work on that this weekend.... thanks for the reminder.

When I remove the spaces it works :(

I do. Just not in the exmaple sorry.
