Hi, I recently made a Search and Replace program, that is suppose to do multiple searches and replaces on lots of files ..like 1000 different files... how i made it work, is it loads the whole file (.htm) into a std::string, then it does the S&R on the string...deletes the old file, and re writes the string to a new file, making the search and replace complete.. the problem with this is that the files I would be doing this on are rather importantant, and this way just doesn''t seem safe enough to use really, especially when i have to delete the whole file and re-write the whole file just to replace maybe one word..and some of the files, are near 50K in size.. Can somone tell me a better way to do a massive search and replace? or just a search and replace in a file, without having to delete it, then re-write it? thanks alot kag1
