inline

问题 I have some inline code in an aspx file that executes: <dd><%= encode(Listing.Address.Line1) %> </dd> Problem is, under certain circumstances the Listing object will be null and therefore references to properties such as Address will throw an exception. How do I handle that exception? I basically want to ignore it: catch it, and then proceed with regular execution/rendering of page. 回答1: Do a null check. It is almost always better to test for the conditions of an exception that you expect

问题 This question already has answers here : In C++ can constructor and destructor be inline functions? (5 answers) Closed 2 years ago . I read a source code of class address_v4 in boost library and there are several constructors declared with BOOST_ASIO_DECL (defined as inline) /// Construct an address from raw bytes. BOOST_ASIO_DECL explicit address_v4(const bytes_type& bytes); /// Construct an address from a unsigned long in host byte order. BOOST_ASIO_DECL explicit address_v4(unsigned long

问题 I am working on a contact form and need some inline javascript form validation. I already have php validation, but I would like to have some active form validation like at http://twitter.com/signup. I would like it to show and hide the p tags after the input.

问题 This question already has answers here : When should I write the keyword 'inline' for a function/method? (13 answers) inline in definition and declaration (2 answers) Closed 4 years ago . #include <iostream> using namespace std; void f(); int main(){ f(); } void f(){ cout << "Hello Stackoverflow!" << endl; } If I wanted to succeed in making this function inline, would I need to specify inline in the declaration or definition, or both? I know that inline functions are normally defined in

问题 I'm trying to invoke an inline powershell script from Task Scheduler to send an email when a particular event is triggered. I can't use the native 'Send an e-mail' action in the Task Scheduler action window because the SMTP server requires SSL and there's no way to specify this in the action window. So I'm looking to 'Start a program' and invoke something to send email but I want to avoid using 3rd party applications such as sendEmail if possible so was hoping to be able to invoke an inline

问题 I am working on the footer section in which I have Social Media Icons and Contact Us section. Here is the fiddle for it. At this moment in the fiddle, Contact Us and Social Media Icons are in separate lines not inline . The HTML code which I have used to order to place Social Media Icons and Contact Us content is: <div class="fixed-bottom footer_fixed"> <p class="mx-0 mb-2 mt-2 text-center"> <i class="fas fa-phone pr-1"></i> <a href="tel:+1234567890" class="pr-3"> +1 234 456 7890 </a> <span

问题 I have the following lines of code in my test_func.rb require 'inline' class TestFunc inline do |builder| builder.c ' int testfunc() { return 0; }' end end I am able to call the function only from an object and not class. I can call it as, obj = TestFunc.new obj.testfunc() But how should i declare so that i can call as, TestFunc.testfunc() 回答1: Use Inline::C#c_singleton instead of Inline::C#c: require 'inline' class TestFunc inline do |builder| builder.c_singleton ' int testfunc() { return 0;

问题 First of all, sorry for my English. Since GCC totally ignores inline specifiers, it's a little difficult for me to know when a funcion has been marked inline by me or not. What I'm trying to understand is, when you have some redeclarations of a same function (in a same translation unit or in different ones), when or under which circunstances your function is marked inline or not (irrespective of what will the compiler make with your hint). For example: inline void print(); void print(); or:

问题 I have observed, in some of the my header file some of the functions are covered but some functions are not getting hit even if the function is called. I have used the following options while compiling. -fno-elide-constructors -O0 -fprofile-arcs -ftest-coverage -fno-inline -fno-inline-small-functions -fno-default-inline I am not able to figure out why it is happening. I am using gcc compiler and gcov. example: hpp Class myclass { Myclass(); Getvalue(); }; 0 Inline myclass::myclass() 0 { 0 ...
