text-files

问题 I wanna map given strings from a text file to blocks, I mean actually draw blocks. I already have a BLOCK class which works, with the following constructor: public class Block implements Collidable, Sprite, HitNotifier { private List<HitListener> hitListeners; private Color color; private Rectangle rectangle; /** * Instantiates a new collidable Block. * * @param rectangle a given rectangle * @param color the color of the block */ public Block(Rectangle rectangle, Color color) { this.color =

问题 How do you open a textfile and write to it with php appendstyle textFile.txt //caught these variables $var1 = $_POST['string1']; $var2 = $_POST['string2']; $var3 = $_POST['string3']; $handle = fopen("textFile.txt", "w"); fwrite = ("%s %s %s\n", $var1, $var2, $var3, handle);//not the way to append to textfile fclose($handle); 回答1: To append data to a file you would need to open the file in the append mode (see fopen): 'a' Open for writing only; place the file pointer at the end of the file. If

问题 I cannot include any text file in my Doxygen documentation. The only exception is a README.md file that I set as the main page. In particular, I would like to see the Changelog.txt file in the documentation. I tried to add it explicitly in the INPUT field and in the FILE_PATTERNS field, without success. In the generated HTML documentation, I cannot find anything neither in the file list nor making a search. The only trace is in Doxygen's log file: Preprocessing C:/Source/Changelog.txt...

问题 The code below is working and creates a Spark dataframe from a text file. However, I'm trying to use the header option to use the first column as header and for some reason it doesn't seem to be happening. I cannot understand why! It must be something stupid but I cannot solve this. >>>from pyspark.sql import SparkSession >>>spark = SparkSession.builder.master("local").appName("Word Count")\ .config("spark.some.config.option", "some-value")\ .getOrCreate() >>>df = spark.read.option("header",

问题 I have a program which uses a text_file to store lots of numbers. When I have to load those numbers I have to load it with 2500 numbers a time. I have a while loop to load it again and again and again... Now, the problem occurs in the while loop I guess. ifstream mfile("abc.txt", ifstream::out); if(mfile.is_open()) { getline(mfile, b); char* ch = new char[b.length() + 1]; strcpy(ch, b.c_str()); result = atof(strtok (ch,";")); while(i<125) { cout<< strtok (NULL,";")<<" "; i++; } i=0; } else {

问题 I have a large text file that contains data from the uniform crime report. Ideally, what I would like to do is only import the data and leave out the other extraneous stuff in the file. The actual data is delimited by spaces and as the data goes onto another "page" the header information repeats itself. I first tried to import the data (and only the data) using the following code and to add my own headers manually: data <- read.fwf("2010SHRall.txt", c(-4,3,8,2,4,5,6,5,4,3,3,4,4,3,3,4,6,5,3,6

问题 excuse the probably simple question (and the terrible layout methods). The code I have successfully writes inputted data to a txt file and on clicking "submit" closes the input window, leaving the "menu" open, with options to add a user (this code) or search properties (unrelated). I can enter one set of details to the txt file with no problem, but when reopening the AddUser window, no matter what is typed in to the boxes the same data is inputted into the file as the previous time, unless

问题 im using python3.3 and a sqlite3 database. I have a big textfile around 270mb big which i can open with WordPad in Windows7. Each line in that file looks as follows: term \t number\n I want to read every line and save the values in a database. My Code looks as follows: f = open('sorted.de.word.unigrams', "r") for line in f: #code I was able to read all data into my database but just to a certain line, i would suggest maybe half of all lines. Then im getting the following error: File "C:

问题 I want to write in a specific line in Textdocument but there´s a Problem with my code, i don´t know where the bug is. set fp [open C:/Users/user/Desktop/tst/settings.txt w] set count 0 while {[gets $fp line]!=-1} { incr count if {$count==28} { break } } puts $fp "TEST" close $fp The File only contains TEST. Has anybody an idea? 回答1: You are using 'w' as access argument, which truncates the file. So you will loose all data from file while opening. Read more about open command You can use 'r+'
