You can start from this code, first read the file, second split the file since data is on different row, then store the result on array: using (StreamReader sr = new StreamReader(@”C:\Folder\Book1.csv”)) { string strResult = sr.ReadToEnd(); string[] result = strResult.Split(new string[] { Environment.NewLine }, StringSplitOptions.None); } 1 solved C# How do I convert a … Read more
Please read your error messages more carefully. You have an autowiring problem: NoSuchBeanDefinitionException: No qualifying bean of type **’com.mthree.service.UserService’** available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} You should add an annotation to tell Spring that your bean is under its control: @Service(value = “userService”) public class UserServiceImpl implements … Read more
You could define a filter function that checks if there is one HTML tag with a attribute value equal to value: def your_filter(tag, value): for key in tag.attrs.keys(): if tag[key] == value: return True return False # alternatively as one liner: def your_filter(tag, value): return any(tag[key] == value for key in tag.attrs.keys()) Then, you could … Read more
You’re getting an ArrayIndexOutOfBoundsException because you’re accessing the command line arguments without checking that there actually are any. You need to check whether the user provided the proper arguments, and if not, print a message how to call the executable as below public class Assignment1 { public static void main(String args[]) { if (args.length == … Read more
in your layout XML file <ProgressBar android:id=”@+id/progress_bar” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:indeterminate=”true” android:padding=”@dimen/padding15″ android:visibility=”visible” /> Then in your Activity or Fragment’s code ProgressBar mProgressBar=(ProgressBar)findViewById(R.id.progress_bar); then you can set it’s visibility property to be invisible or visible: mProgressBar.setVisibility(View.VISIBLE); or mProgressBar.setVisibility(View.GONE); or mProgressBar.setVisibility(View.INVISIBLE); solved How to make a Progress Bar [closed]
You need to add the JButton to mainPanel instead of panel. Some duplicated lines and not necessary settings removed for (int i = 0; i < 64; i++) { label[i] = new JButton(); label[i].setBorderPainted(false); mainPanel.add(label[i]); label[i].setIcon(new ImageIcon(getClass() .getResource(“/org/me/images/O.png”))); label[i].setPreferredSize(new Dimension(50, 50)); label[i].setToolTipText(“label” + i); } 0 solved How do I get rid of the gaps … Read more
You may not have expression statements in the namespace-/file-scope. Only declaration statements are allowed. Declare a function, and write the expressions in the block scope of that function. In particular, I suggest declaring the main function, because a C++ program must contain one. Main function is the entry point of the program. 0 solved C++ … Read more
You can use scheduling in Spring to update it on regular interval (with cron jobs for example). Look at @Scheduled(cron = ”). Also for your token, is there an special reason to keep it in file. Why not use a bean to store it and pass it around with @Autowired? 0 solved Is there any … Read more
As people have said in the comments, this question is something that you might have easily found out for yourself. Since we’re here anyway though, here’s the answer: The .css() function can read both inline styles and separate styles (via link or style tags), but when it does write styles (when it has a parameter), … Read more
You might consider learning how to implement breadth-first searches and depth-first searches in order to accomplish your objective. The following example shows how both of these search strategies can be easily handled in one function. A modular approach should make the code simple to change. #! /usr/bin/env python3 from collections import deque from operator import … Read more
Your factorial() function returns 0 for any input because of how you defined your range. The range builtin starts at 0 unless otherwise defined so: for c in range(n): re = re * c # no semicolons in Python is doing: re = re * 0 on the first iteration so for all subsequent iterations: … Read more
for loop can be simplifed to x= (pow(3,n)-1)/2 I have double checked this here:http://www.wolframalpha.com/input/?i=sum+pow%283%2Ci%29+for+i+from+0+to+%28n-1%29 3 solved Convert loop into mathematical equation
The <f:view> runs as being a taghandler during view build time, setting the specified attributes as properties of the current UIViewRoot and/or the HttpServletResponse instance. So, if some taghandler (not UI component!) is encountered before the <f:view> and relies on one of those attributes, then it will miss hit. However, <rich:page> is an UI component … Read more
Why does c++ standard still not include file system and networking? Do you have any clue, why the C++ standard committee is not even thinking about adding such an essential features in the future? No, mainly because that is not true!There are ongoing efforts to define standard support for both. Personally, I don’t see why … Read more
The idea is to avoid the issue of new lines by not using the dot ($subject is your string): $pattern = ‘~ Project\hNo\.\h\d++\hDATE\h (?<date>\d{1,2}\/\d{1,2}\/\d{1,2}) \s++No\.\hQUESTION\hANSWER\s++ (?<No>\d++)\s++ # all characters but D or D not followed by “ate Required” (?<desc>(?>[^D]++|D(?!ate\hRequired))+) \D++ (?<date_required>\d{1,2}\/\d{1,2}\/\d{1,2}) ~x’; preg_match_all($pattern, $subject, $matches, PREG_SET_ORDER); print_r($matches); Note that i use possessive quantifiers and atomic … Read more
