由 天涯浪子 提交于 2020-01-05 06:03:15
问题 With the code below now working can anyone suggest how I pull out the image from the collection at a larger size, this is only working for thumbnails at the moment. <?php if(!hook("EditorsPick")): /* ------------ Collections promoted to the home page ------------------- */ $home_collectionsx=get_home_page_promoted_collectionsx(16); foreach ($home_collectionsx as $home_collectionx) { ?> <div class="EditorsPick"> <div class="HomePanel"><div class="HomePanelINtopEditors"> <div class=

CPP-STL：vector中的size和capacity

由 我们两清 提交于 2020-01-05 05:27:06
在 vector 中与 size() 和 capacity() 相对应的有两个函数： resize(size_type) 和 reserve(size_type) 。 Size 指目前容器中实际有多少元素，对应的 resize(size_type) 会在容器尾添加或删除一些元素，来调整容器中实际的内容，使容器达到指定的大小。 Capacity 指最少要多少元素才会使其容量重新分配，对应 reserve(size_type new_size) 会这置这个 capacity 值，使它不小于所指定的 new_size 。 所以用 reserve(size_type) 只是扩大 capacity 值，这些内存空间可能还是“野”的，如果此时使用“ [ ] ”来访问，则可能会越界。而 resize(size_type new_size) 会真正使容器具有 new_size 个对象。 在对 vector 进行访问时，如果使用“ [ ] ”，则会像变通数组那样，不进行越界的判断。如果使用“ at(size_type) ”函数则会先进行越界的判断，例如下面两断程序： 程序一： vector<int> v; v.reserve(2); v[0]=1; cout << v[0] << endl; 程序二： vector<int> v; v.reserve(2); v.at(0)=1; cout << v

Representation of Long Integers [duplicate]

由 那年仲夏 提交于 2020-01-05 05:01:08
问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: What is the difference between an int and a long in C++? #include <iostream> int main() { std::cout << sizeof(int) << std::endl; std::cout << sizeof(long int) << std::endl; } Output: 4 4 How is this possible? Shouldn't long int be bigger in size than int ? 回答1: The guarantees you have are: sizeof(int) <= sizeof(long) sizeof(int) * CHAR_BITS >= 16 sizeof(long) * CHAR_BITS >= 32 CHAR_BITS >= 8 All these conditions

c# richtextbox outofmemory

由 强颜欢笑 提交于 2020-01-04 14:28:21
问题 I have written an app that reads incoming chat(somewhat like an instant messenger), formats it and inserts it into a richtextbox. If you leave the program running long enough you will get an out of memory error. After looking at my code i think this is because i am never trimming the richtextbox. The problem that i'm running into is i don't want to call clear() because i don't want the visible text to disappear. I was thinking maybe i should keep a List with a max size of somthing like 200

How to get the size of a label before it is laid out?

由 坚强是说给别人听的谎言 提交于 2020-01-04 14:14:11
问题 I read this old answer on how to accomplish this. But since it involves using impl_processCSS(boolean) , a method that is now deprecated, I think we need to update the answer. I've tried placing the label inside a HBox and then get the size of it, or getting the size of the HBox, without any luck. And I've also tried using .label.getBoundsInLocal().getWidth(). SSCCE: import javafx.scene.control.Label; import javafx.scene.layout.HBox; import javafx.application.Application; import javafx.scene

Android Layout Same Relative Size on ALL Screen Sizes

由 不羁岁月 提交于 2020-01-04 13:13:40
问题 A problem that has been nagging me for weeks now, tried everything but to no avail. What I want to do is have the EXACT SAME layout on EVERY screen size. Let me illustrate by using a picture: On a 2.7 inch device: On a 10.1 inch device (badly photoshopped image for illustration purposes): But with the current Android implementation, i get this on 10.1 inch devices: In short, i want my application to look the same (relatively speaking) including button sizes, text scaling etc etc on all screen

Why is a C++ Hello World binary larger than the equivalent C binary?

由 |▌冷眼眸甩不掉的悲伤 提交于 2020-01-04 13:12:21
问题 In his FAQ, Bjarne Stroustrup says that when compiled with gcc -O2, the file size of a hello world using C and C++ are identical. Reference: http://www.stroustrup.com/bs_faq.html#Hello-world I decided to try this, here is the C version: #include <stdio.h> int main(int argc, char* argv[]) { printf("Hello world!\n"); return 0; } And here is the C++ version #include <iostream> int main(int argc, char* argv[]) { std::cout << "Hello world!\n"; return 0; } Here I compile, and the sizes are

How to change font size of NSTableHeaderCell
