Kirat Try this: var emailpat = /^[^@]+@[^@]+\.[^@\.]{2,}$/; Email addresses should have just one @-sign, and that can’t be the first character. After the @ you’ll need at least one dot followed by 2 or more letters. And yes, this also accepts email addresses that are not valid. If you want to be sure that the user … Read more
Excellent idea! Here’s a program that prints “hellohello” five times: int i; void print_twice(const std::string& s) { for (i = 0; i < 2; i++) { std::cout << s; } std::cout << std::endl; } int main() { for (i = 0; i < 5; i++) { print_twice(“hello”); } } Or… does it? (Ominous organ music … Read more
The definite answer is this: function preventDot(e) { var key = e.charCode ? e.charCode : e.keyCode; if (key == 46) { e.preventDefault(); } } And bind it on keypress solved Don’t let a user type the period character in an HTML5 input type number
You can do it like this to iterate the whole array column-wise: // Get the maximum number of columns among all rows. int maximumColumns = 0; for (double[] row : multi) { if (row.length > maximumColumns) { maximumColumns = row.length; } } for (int column = 0; column < maximumColumns ; column++) { for (int … Read more
Solution is very simple – need to add: Database=myDataBase; to CONN_STR = ‘DRIVER=SQL Server Native Client 10.0;UID=user;PWD=pass;server=server;’ + ‘Trusted_Connection=No;MARS_Connection=yes’;Database=myDataBase; Thanks Arnaud for great framework!!! solved Delphi: What’s wrong with REST API based on mORMot?
There is no instance or extension method in .NET for a sequence of strings that will join them together as String.Join does. If you want such an extension method you’ll have to write it yourself (which should be trivially easy, given that internally all it needs to do is call string.Join). Enumerable.Join, which is the … Read more
Using Flexbox, you can use order. .container{ display:flex; } .order-1{ order:1; } .order-2{ order:2; } .order-3{ order:3; } @media(min-width:992px){ .order-lg-1{ order:1; } .order-lg-2{ order:2; } .order-lg-3{ order:3; } } <div class=”container”> <div class=”order-3 order-lg-2″>A</div> <div class=”order-2 order-lg-1″>B</div> <div class=”order-1 order-lg-3″>C</div> </div> 0 solved How to change order of elements when device is mobile [duplicate]
As mentioned std::vector::push_back() may invalidate your iterator. Possible, but pretty ugly solution could be: for (auto beg = v.begin(); beg != v.end();++beg) { if (beg == v.begin()) { v.push_back(50); beg = v.begin(); } } but your logic seems convoluted, why not push back just before the loop? 4 solved C++ why this code doesn’t work? … Read more
Adding strings concatenates the strings. Use TryParse to parse the strings into integers or doubles. Remember to check the return value! You must handle the case where the user fails to type in a valid number. The reason I use the var keyword is because I want the person who is playing be able to … Read more
This is a clever nearly one-liner that should do the job: $result = array_map(function($line) { return preg_split(‘/\s+/’, $line); }, explode(“\n”, $text)); First explode() the $text to separate lines, then preg_split() it by spaces. 2 solved How to split this text into columns
All three options to check for empty container are more or less equivalent. Using empty() shows (as denoted in the comments already) most obviously your intention and as a little bonus, it is even the shortest one to write (that’s for the lazy ones like me…). How it is implemented? Vendor specific, probably inlined. Option … Read more
That is an ISO date. The Z stands for Zulu but means UTC time. Try: [formatter setDateFormat:@”yyyy-MM-dd’T’HH:mm:ssZZZZZ”]; To feed your initial nsdate. 4 solved Converting timestamp string with T and Z characters to NSDate [duplicate]
The book you are reading is crap. Avoid the book and tell others to do the same. <conio.h> is a system-specific header and not guaranteed to be available on many platforms. The result of fgetc must never be stored in a char variable. The function feof must never be used in a loop condition. The … Read more
