fine, so u read the file content into a buffer, don't see u initialize
row ==0?
you don't say what content[] type is, CString array? the statement
content[row++].Format.. is a bit awkward. Try instead content[row++]
= data; since data is a string since you use fgets.
Ok so lets assume your array content[] is big enough
if( content[row-1].Find( " /noguiboot /bootlogo" ) != -1 )
{
now if you b4 at least got one row this will work, if row==0 then u
are in for a nasty surprise.
content[row-1].Replace(" /noguiboot /bootlogo", "");
you remove some string. ok
file = fopen("C:\\text.txt", "wt+");
u never check return values like from fopen, did the function succeed?
now you want to write the new contents to another file, 'wt' would do
btw as wt+ makes no sense here
int line = 0;
while(line != row)
a for loop would be better for (line = 0; line != row; ++line)
{
** fwrite(content[line], sizeof(char), content[line].GetLength(), file);
you write line using fwrite.. ok why not use fputs since you read with
fgets? fwrite is used to write binary stuff like a struct or something
try to split up lines more, there is no price for obfuscating your
code, the clearer the better and let the compiler do the optimization
for u. it is just n00b-lame to try and put as much functionality in
one line-> makes code unreadable and error prone.
line++;
}
fclose(file);
}
