Hai, Thank you for your response. I have catched the exception.Now the program does not crash but the searching is incomplete. Even if the file is of encoding type utf16 ,the exception occurs(I have used a message box to show reason of exception). Is the problem due to reading the file and storing in char array or due to making the regex expression. I have attached the file in which i am searching. Hope you can help me.
The first byte in the file is 0xFF which is not a valid UTF8 character, likewise the second byte is 0xFE which is also not used in UTF8: so there's no way to decode the file and convert to UTF32. However, if I start reading from the third byte in the file, then the search does go through to the end: I can't guarentee that the content was correct though ! John.
