问题 I have a new problem that bugs me ... I am making a web page that I want to be fixed with no scrolling and most important I want my main Div to fill aaaaaaaaall my available space... I made this code <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd "> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml"> <head> <title>There is a @#!¤*-ing blank !</title> <style type='text/css'> html {margin:0px;padding

C# equivalent to Java RSA/ECB/OAEPWithSHA-256AndMGF1Padding

阅读更多关于 C# equivalent to Java RSA/ECB/OAEPWithSHA-256AndMGF1Padding

问题 I am trying to encrypt at string in Java and decrypt in C#. I tried with RSA/ECB/PKCS1PADDING first and it worked like a charm, but now I'm trying to switch to OAEP padding, but I cannot make it work. The encryption works fine but not the decryption. The only things I changed was the algorithm name in Java and in C# I changed rsa.Decrypt(data, true) from false to true. Does it require more changes? The exception I get is "Error occurred while decoding OAEP padding". My Java encryption method:

问题 Why h1, h2, h3 elements margins are ignored when in div? http://jsfiddle.net/TzmdZ/ <div class="col"> <h3>This is header</h3> </div> <div class="col"> <h3>This is header</h3> </div> .col { background: gray; margin-bottom: 1em; } .col h3 { margin-bottom: 1em; } When I put h element into div and there is no other text in it, though h element and div element bottom margins are spicified, h bottom margin is ignored. 回答1: Assigning margins to two siblings will cause the margins to collapse where

Why Doesn't IE7 recognize my css padding styles on anchor tags?

阅读更多关于 Why Doesn't IE7 recognize my css padding styles on anchor tags?

问题 My site is working fine in Firefox, Safari, Chrome, and Opera, but for some reason IE7 is not recognizing css padding on any anchor tags. I can't figure this out. In IE7, if you look at the tabs that say "exclusives|popular|recent comments" on the homepage http://revolvermag.com, you'll see that there is no padding getting applied. I've worked around the padding not getting applied to anchor tags elsewhere on the site, but here it looks especially bad. Anyone know of CSS fixes for this? 回答1:

Remove Text Padding/Margin inside VML Shape

阅读更多关于 Remove Text Padding/Margin inside VML Shape

问题 I'm trying to figure out how to get this text (!) to show up. Even though it's smaller than the circle it's in, it still gets cut off about 1/3 of the way in to the circle. I would like to use this for Outlook specifically. <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" style="height:20px;v-text-anchor:middle;width:20px;" arcsize="50%" stroke="f" fillcolor="#ffcb05"> <center style="color:#ffffff;font-family:sans-serif;font-size:16px;font

TransitionDrawable doesn't account for padding?

阅读更多关于 TransitionDrawable doesn't account for padding?

问题 I tried the accepted solution posted here, but it appears to ignore padding. When the second view (in this case a button) displays, it's much smaller than the original which has padding. Is there a workaround for that? Thanks 回答1: Yes, TransitionDrawable extends from LayerDrawable which ignores the padding. This is the getPadding() method in the base Android code, which gets rid of anything you specified: @Override public boolean getPadding(Rect padding) { // Arbitrarily get the padding from

Compile-time check to make sure that there is no padding anywhere in a struct

阅读更多关于 Compile-time check to make sure that there is no padding anywhere in a struct

问题 Is there a way to write a compile-time assertion that checks if some type has any padding in it? For example: struct This_Should_Succeed { int a; int b; int c; }; struct This_Should_Fail { int a; char b; // because there are 3 bytes of padding here int c; }; 回答1: Since C++17 you might be able to use std::has_unique_object_representations. #include <type_traits> static_assert(std::has_unique_object_representations_v<This_Should_Succeed>); // succeeds static_assert(std::has_unique_object

MySQL aes_encrypt padding scheme?

阅读更多关于 MySQL aes_encrypt padding scheme?

问题 Does anyone know what padding scheme mysql uses for their aes_encrypt? I've done a lot of googling, and all I found was "byte padding". But that's too general! Thanks 回答1: The data padding is done per RFC3369/PKCS#5. Keys are zero padded. Unfortunately, neither of these are documented, but I got the information from this bug report: http://bugs.mysql.com/bug.php?id=16713 回答2: Here's a good explanation with code that demonstrates how the padding works. 回答3: If you don't know what padding is

TabControl padding doesn't work with classic theme

问题 Does anyone know why the padding property of TabControl doesn't render with classic theme but works for luna theme? The XAML is very basic. I've made the left padding 50 so that the problem is obvious in the screenshots.  <Style TargetType="{x:Type TabControl}"> <Setter Property="BorderBrush" Value="Black" /> <Setter Property="BorderThickness" Value="1,1,1,1" /> <Setter Property="Padding" Value="50,5,10,5" /> <Setter Property="Margin" Value="3.5" /> <Setter

How to use sprintf function to add leading “0” instead of spaces to character?

问题 I am trying to use sprintf function to add leading "0" to character, and make all charaters the same length. However what I get is leading space. My code: a <- c("12","123", "1234") sprintf("%04s",a) [1] " 12" " 123" "1234" What I tried to get: [1] "0012" "0123" "1234" The sprintf manual says: "For characters, this zero-pads on some platforms and is ignored on others."
