Hi all,

I have one text file, now I want to find a string in that file and have to replace with some other string(nothing but find and replace a string in text file). I am trying to use CFile class in MFC, but it has limited methods to do such operations. can any body give some idea to accomplish this or if you have any such application please send me for reference.

Thanks in advance.

Regards,
anil

CFile provides file handling (open, close, read, write) methods, as it should. You have to

Read the file (maybe partially) in a buffer (for instance in a CString object)
do the replace operations in the buffer (CString class has methods to do it)
Save the modified buffer to disk using, again, CFile.
