You can’t, plain and simple. The ‘#’ character is reserved for preprocessor directives in C#. I also question the urgent need to name an array reference ‘F#’. 1 solved Can’t add a # sign to the name of an array in C#
Here are the required steps: Use the u pattern option. This turns on PCRE_UTF8 and PCRE_UCP (the PHP docs forget to mention that one): PCRE_UTF8 This option causes PCRE to regard both the pattern and the subject as strings of UTF-8 characters instead of single-byte strings. However, it is available only when PCRE is built … Read more
I don’t understand the need of your “reports” table,… If I was you I’ll use only ShowData() with the query, like this public void ShowData() { con = new SqlConnection(@”Data Source=LAPTOP-KA7UGSG3;Initial Catalog=JAPoultry;Integrated Security=True”); con.Open(); da = new SqlDataAdapter(“SELECT Variety, SUM(Quantity) FROM Inventory GROUP BY Variety”, con); dt = new DataTable(); da.Fill(dt); dgv_Reports.DataSource = dt; } … Read more
The comparison userid = (null OR ”) is invalid. First, the very syntax is wrong: field = (value1 OR value2) should be put either as (field = value1) OR (field = value2) or as field IN (value1, value2) Second, null is a special value, which stands for unknown, doesn’t matter, unapplicable etc. and that’s why … Read more
Here is a generic method regardless of the level of the hierarchy. SQL — DDL and sample data population, start DECLARE @tbl table ( idGeo INT IDENTITY PRIMARY KEY, GEO VARCHAR(64), PARENTID INT ); insert into @tbl (GEO, PARENTID) values ( ‘EMEA’, NULL), ( ‘France’, 1), ( ‘mIDCAPSfRANCE’, 2), ( ‘Germany’, 1), ( ‘France exl … Read more
Here is an efficient solution. For each element in the second list, get the next element of the first one until you have a match. If you reach the end of the first list before you matched all, this is False else True def check(a, b): i = iter(a) return all(e in i for e … Read more
Well, as I understand, you have different input fields and you want only those that have values != 0. You can use this pseudo code which traverses thru all input fields and your code will execute only if value != 0: $(‘input’).each(function() { if ($(this).val() != 0) { // code goes here… } }); $(‘input’).on(‘change’, … Read more
JAR files are typically compiled Java code, which can be opened by the Java Virtual Machine. Java is owned and updated by Sun Microsystems. SWF files are compiled ActionScript code, which can by opened by the ActionScript Virtual Machine. ActionScript (used by Flash) is owned and updated by Adobe. The two are similar, but created … Read more
To find out DST transitions, you could access Olson timezone database e.g., to find out the time of the next DST transition, in Python: #!/usr/bin/env python from bisect import bisect from datetime import datetime import pytz # $ pip install pytz def next_dst(tz): dst_transitions = getattr(tz, ‘_utc_transition_times’, []) index = bisect(dst_transitions, datetime.utcnow()) if 0 <= … Read more
Recursion works by breaking down each problem to a “smaller” version of the same problem. In this case, you can insert this code: elif n < 0: return False elif is_buyable(n – 20) or is_buyable(n – 9) or is_buyable(n – 6): return True 4 solved Python Recursion Puzzle: Buying n McNuggets at McDonalds (using 6, … Read more
I had this same issue. I assume you don’t have a height set on the green block because you want it to fill up the remaining space of the keyboard. If you want the keyboard to be a CONSTANT height you can simply set a height constraint on the green block and you’re done, but … Read more
The # symbol indicates that it’s an ID selector, so it will only apply to the single element that has that particular ID on the page. You’re incorrect about example A – that’s actually a selector for the element with the ID input, not a general selector for all inputs. The . symbol indicates that … Read more
Are you trying to import like this: from bs4 import BeautifulSoup If not, try it that way. Hope this helps! (Perhaps you should add your import statement to the question so we can see if there is a problem with the statement or if the issue resides somewhere else) 1 solved cannot import name module … Read more
In c#, the timezone is built into the DateTime structure, so you should not need to set the default. Instead when you are manipulating DateTime instances you use the UTC version of methods. For example, in the constructor you can specify if the date supplied is local or UTC. With regards to the second question, … Read more
Neither of the two are correct. In PHP var1 will get that value in the function. In JS, if you don’t want to assign something to the first parameter, make it null. do_it(null, ‘something_cool’); And then inside the function, check if it’s null and perhaps give it a default value if it is. Or just … Read more
