search

问题 I am working on a school project that has several pdf files. There should be a search by name functionality that I just type in the student's name and all the pdf files with his/her name should open. What is the best way to do this? I've looked for solutions on the net and all I am coming up with is iTextSharp and it's making more confused. Is this possible? Maybe someone can please give me a link to a tutorial, or something. :) Thank you very much. 回答1: Use iTextSharp. It's free and you only

问题 BASED ON OUT DATED BETA Is there support for the Search Button yet in WinPhone 7 sdk? I can't find it, nor anything info on it.

问题 I've got a website for which I just wrote a great search function. I just realized that I have some words in my db with accent marks. So when somebody types in the word to search for, without the accent mark of course, they don't find what they are looking for. most search functions have solved this problem by now; how do they do it? There must be some clever trick to it. Most of my queries use mysql's MATCH feature but one of them uses LIKE. 回答1: You need to set a particular collation on

问题 I have: data = [[u'text'],[u'element'],[u'text00']] pattern = text pattern2 = EL pattern3 = 00 Using regex I want to search and return: text, text00 # for pattern element # for pattern2 text00 # for pattern3 回答1: import re data = [[u'text'], [u'element'], [u'text00']] patterns = [u'text', u'EL', u'00'] results = [] for pattern in patterns: results.append([x[0] for x in data if re.search(pattern, x[0], flags=re.I)]) print results or, more concisely: import re data = [[u'text'], [u'element'],

问题 This question already has answers here : if not exists insert in MySql (2 answers) Closed 6 years ago . I'm a Java developer who just got handed the task of "some quick easy DB stuff" - except I don't know much about PHP/MySQL...I need to insert a record into a DB - but only if the email field doesn't match one that already exists in the DB. Here's what I've gleaned so far for my PHP code: // Grab the values from the HTML form: $newUserName = $_POST['newUserName']; $newUserName = $mysqli-

问题 Let's say I have String Table that have a few strings (like mother, father, son) and now in this String Table I want to find every word that contains string "th" for example. How should I do it? Method string.equals(string) won't help here. 回答1: Use the contains or indexOf methods, depending on whether you need the position. 回答2: The following snippet should be instructive: String[] tests = { "father", "mammoth", "thumb", "xxx", }; String fmt = "%8s%12s%12s%12s%12s%n"; System.out.format(fmt,

问题 I am trying to create a search feature in my program similar to google search bar, where when user is typing it actually searches the database and displays the current result in a pop-out list below the JTextField . I am new to java GUI programming therefore I am unclear about all the java components therefore it is hard to find suitable components which fulfil my needs, especially the component I need to use for the pop out drop down list below the text field. I hope some experts can show me
