问题 This is what my Table View looks like. Each cell Strings a text from a .txt Search Filter works fine. But When I select one of the results e.g. "How" it prints the the Content of "Hello" instead. I'm thinking this is probably because "Hello" is programmed as the first String so it will always be the result of the first cell when clicked. I am needing help with figuring out how the search results are linked to it's own content. if that makes any sense? Here's the code below. The code reads

问题 Now I am working on extracting information from a text file in Ruby.

问题 Every time the code is executed I want a new Text File to be created. The Text File should be called Person1. Next time code is executed the Text File should be called Person2.

问题 This question already has an answer here : Max function in python returning wrong results (1 answer) Closed last year . I am using python 2.7 to find highest and lowest values in an text file. The text file is simply formatted with one Integer value at each line. The following code collects the numbers from the file: with open(data_file, 'r') as f: data_list = f.readlines() Then I try to reach for the maximum and minimum values with: max_value = max(data_list) min_value = min(data_list) print

问题 I'm trying to read in a text file of 5000 lines. However I only want to get the first 10 lines of every 100 lines. So line 1-10, line 101 - 110, line 200 - 210 etc. I just cant figure out the logic to use. $count = count(file($text)) for ($i = 0; $i < $count; $i++) { $test = fgets($f_text) } 回答1: Use % 100 and only print lines where $n % 100 > 0 && $n % 100 <= 10 . $lines = file($text); foreach ($lines as $n => $line) { if ($n % 100 > 0 && $n % 100 <= 10) { echo $line; // or whatever } } A

问题 I have a text file that's appended to over time and periodically I want to truncate it down to a certain size, e.g. 10MB, but keeping the last 10MB rather than the first. Is there any clever way to do this? I'm guessing I should seek to the right point, read from there into a new file, delete old file and rename new file to old name. Any better ideas or example code? Ideally I wouldn't read the whole file into memory because the file could be big. Please no suggestions on using Log4Net etc.

问题 I have a text file that starts like this: [Details] Version=100 Switch=340 Video=800 Date=20100912 Length=00:49:34.2 Days=1 hours=20 Is there a way that I can check each line within the [Details] section and then do something like this? if(line == "version") { // read the int 100 } Also there is other text in the text file that is of no interest to me. I only need to find the [Details] part. 回答1: using (StreamReader sr = new StreamReader(path)) { while (sr.Peek() >= 0) { var keyPair = sr

问题 Looking for help with my program. There is a text file with 5 first and last names and a number grade corresponding to each person. The task is to create a user name and change the number grade to a letter grade.
