Min-Height 100%?

阅读更多关于 Min-Height 100%?

问题 I want to be able to have a container element which contains the content to repeat and expand as the content goes on, but the container per se is in between two elements in which give heed of the container element "stopping" at some point. You may view the design at: http://www.noxinnovations.com/portfolio/charidimos/ What I want to do is have the container element which contains the content to be set at 100%. So no matter what it will always be correct in size without a set size. Any ideas?

Captured image returns small size

阅读更多关于 Captured image returns small size

问题 I am capturing the image from camera. The captured image's size shows too small when captured. But later if I check in gallery the captured image size shows in MB. I tried debugging the code, so while debugging I checked length of the file after image is captured the length shows 26956 bytes, and when I checked same image in gallery the size of the image is 1.3 MB. Why the image size shows reduced when captured? private void cameraIntent() { Intent intent = new Intent(MediaStore.ACTION_IMAGE

return biggest/highest object from jquery elements

阅读更多关于 return biggest/highest object from jquery elements

问题 Howdey! Let's take a look at the following jQuery function: $.fn.getMax = function() { return this.height(Math.max.apply(this, $(this).map(function(i, e) { return $(e).height(); }).get())); }; It returns and sets the heighest height for all selectors. But what is, if you want to return the object (not the height) with the heighest value? So if you call the function like this: $(selector).getMax().css({backgroundColor: "indigo"}); ...how the element with the heighest height gets the

folder size wrong

阅读更多关于 folder size wrong

问题 This code is correct but the folder size is wrong. If I change the directory the size is always wrong. For example the size of "%@/Caches/com.apple.Safari/Webpage Previews" is 23 MB, but I have 16.5 KB. NSString *path = [NSString stringWithFormat:@"%@/Caches/com.apple.Safari/Webpage Previews", [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0]]; NSNumber *fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil]

strlen of a char array is greater than its size. How to avoid?

阅读更多关于 strlen of a char array is greater than its size. How to avoid?

问题 I defined an array: char arr[1480]; Now, from a file, I read exactly 1480 chars and put into arr (by doing arr[i]=c). I know 1480 chars because I use a while loop to read one char ar a time (istream.get()) and stop when the incrementing index = 1480. However, after that, I do strlen(array) and it returns 1512. How come? This only happens in some occasions, but not in all occasions, even though every time I read from file, I always read up to 1480 chars. My doubt is one char might occupy more

c++: Does gcc provide extended macro/function like “countof” the size of an array?

阅读更多关于 c++: Does gcc provide extended macro/function like “countof” the size of an array?

问题 VC provides a macro called "_countof" inside "stdlib.h", will calculates in compile time, the number of an array's elements. My question is does gcc provide a similar utility? Thanks. 回答1: In C++17, the std::size function template will return the size of an array or container. A possible implementation is given, so you can write your own until C++17 becomes available: template <class T, std::size_t N> constexpr std::size_t size(const T (&array)[N]) noexcept { return N; } This will work on any

Calculate size in Hex Bytes

阅读更多关于 Calculate size in Hex Bytes

问题 what is the proper way to calculate the size in hex bytes of a code segment. I am given: IP = 0848 CS = 1488 DS = 1808 SS = 1C80 ES = 1F88 The practice exercise I am working on asks what is the size (in hex bytes) of the code segment and gives these choices: A. 3800 B. 1488 C. 0830 D. 0380 E. none of the above The correct answer is A. 3800, but I haven't a clue as to how to calculate this. 回答1: How to calculate the length: Note CS. Find the segment register that's nearest to it, but greater.

Ada types size difference

问题 I have this Ada program: with Ada.Text_IO, Ada.Integer_Text_IO; use Ada.Text_IO, Ada.Integer_Text_IO; procedure test is type MY_TYPE is new Integer range 1..20; subtype MY_TYPE2 is MY_TYPE range 5..6; c : MY_TYPE:=10; f : MY_TYPE2 :=6; begin put(Integer(c'SIZE)); end test; and when I run it I get 32. If I replace type MY_TYPE is new Integer range 1..20; with type MY_TYPE is range 1..20; I get 8. What is the difference between the two declarations? 回答1: You are allowing the compiler to choose
