| Typically the answer is: read source file line by line/word by word/etc make changes save to temp file close files delete source file rename temp file to source file another possibility is: load source file into memory (say, a std::deque) make changes save memory to source file Good luck! | |

| hi, Duoas , i choose to use the method of load source file into memory (::deque) the line is "goes Goes I am Phappy"--> i want to change to "goes Goes I am happy" change the line "goes Goes I am Phappy"--> " " by ReadFile(happy.txt,...) // put the line into a wstring setFilePointer( ); writefile(); the problems come, i just know how to insert string into a file, by how to override or delete, it really a problem~ ~ | |

| ReplaceFile() Replaces one file with another file, with the option of creating a backup copy of the original file. The replacement file assumes the name of the replaced file and its identity. http://msdn.microsoft.com/en-us/library/aa365512(VS.85).aspx DeleteFile Function() Deletes an existing file. http://msdn.microsoft.com/en-us/library/aa363915(VS.85).aspx MoveFile Function Moves an existing file or a directory, including its children. http://msdn.microsoft.com/en-us/library/aa365239(VS.85).aspx | |
