阅读更多关于 how to set padding to listview items?

问题 I have a Listview on Large icon view in Windows Forms that the images are so close to each other. so how could I set padding to items ? 回答1: There is no method within ListView to do this. You could take a look at LVM_SETICONSPACING. Here is a very good tutorial, if you need help. 回答2: You can use the IndentCount property. 来源： https://stackoverflow.com/questions/12026301/how-to-set-padding-to-listview-items

how to make a ul li css menu with variable space between items

阅读更多关于 how to make a ul li css menu with variable space between items

问题 The idea is to make a menu with a fixed amount of items. Each of the items must have a fixed padding on them to make them look decent when placing a border around them. (so far so good) But these items must be spread out in a div with a fixed size, spaced evenly - the items themselves won't be the same size as this is dependent on the text within these items. What I can't figure out is how to make sure that the items are on 1 line with a dynamic (more or less) evenly spacing between them

Programmatically assigning Margin and/or Padding to a Label

阅读更多关于 Programmatically assigning Margin and/or Padding to a Label

问题 In trying to get some labels in a TableLayoutPanel to move from the top left of their cells to the center of the cells, I'm trying to experiment with adding padding and/or margins. However, nothing I've tried works. Here's the code I've tried and the results: // Setting the padding just cuts off the bottom part of the text //lbl.Padding = new System.Windows.Forms.Padding(1); // How to set Margin? //lbl.Margin = new System.Windows.Forms.Margin(1); <- This mimics "Padding" but is not recognized

tensorflow学习笔记——AlexNet

　　2012年，Alex Krizhevsky、Ilya Sutskever在多伦多大学Geoff Hinton的实验室设计出了一个深层的卷积神经网络AlexNet，夺得了2012年ImageNet LSVRC的冠军，且准确率远超第二名（top5错误率为15.3%，第二名为26.2%），引起了很大的轰动。AlexNet可以说是具有历史意义的一个网络结构，在此之前，深度学习已经沉寂了很长时间，自2012年AlexNet诞生之后，后面的ImageNet冠军都是用卷积神经网络（CNN）来做的，并且层次越来越深，使得CNN成为在图像识别分类的核心算法模型，带来了深度学习的大爆发。　　下面首先学习AlexNet网络的创新点，然后在学习AlexNet的网络结构，最后在用代码实现AlexNet。 1，AlexNet网络的创新点　　AlexNet将LeNet的思想发扬光大，把CNN的基本原理应用到了很深很宽的网络中。AlexNet主要使用到的新技术点如下：　　（1）成功使用ReLU作为CNN的激活函数，并验证其效果在较深的网络超过了Sigmoid，成功解决了Sigmoid在网络较深时的梯度弥散问题。虽然ReLU激活函数在很久之前就被提出了，但直到AlexNet的出现才将其发扬光大。　　在最初的感知机模型中，输入和输出的关系如下：　　虽然只是单纯的线性关系，这样的网络结构有很大的局限性

Python: ImportError from compiled source code

阅读更多关于 Python: ImportError from compiled source code

问题 I'm having problems while running a compiled source code. The code itself is correct and if I run python file.py everything goes fine; if I compile it with pyinstaller or software like this, and then I run the compiled file it says ImportError: No module named _cffi_backend . But when I open python and import cffi and/or _cffi_backend python doesn't show error. Investigating in my code I found that the problem is just with padding from cryptography, so if I don't import padding the output

Reflection padding Conv2D

问题 I'm using keras to build a convolutional neural network for image segmentation and I want to use "reflection padding" instead of padding "same" but I cannot find a way to to do it in keras. inputs = Input((num_channels, img_rows, img_cols)) conv1=Conv2D(32,3,padding='same',kernel_initializer='he_uniform',data_format='channels_first')(inputs) Is there a way to implement a reflection layer and insert it in a keras model ? 回答1: The accepted answer above is not working in the current Keras

PreferenceActivity works properly on Android 2.1, but not 4.1 (padded)

问题 I'm writing an application. It needs to run on old android OS's to be useful. I have written the preferences screen using a PreferencesActivity that populates with a options.xml file that contains PreferenceScreen. It has no submenu for preferences (so PreferenceFragment provides no real benefits). In Android 2.1 (2.2 and 2.3, haven't tested on ICS yet) the screen displays properly like so in landscape: But on Jellybean, it looks like this: It looks terrible. I have nothing defined as a

问题 I have a div with border-radius. It is displayed with some kind of fragemnts in IE10 and IE11. What is the cause? How do we fix this? Visit this site with either IE10 or IE11 to see the effect: http://css3pie.com/demos/border-radius Visit to fiddle: http://goo.gl/pKLe89 回答1: IE10 and IE11 both support border radius. Although, some claim that the 4 missing pixels do exist, you may be able to go that route. Another option is to atempt to hack it. -ms-border-radius: 10px; 回答2: These are the

How to set the margin on a internal TextBoxView in wpf

阅读更多关于 How to set the margin on a internal TextBoxView in wpf

问题 I have a case where I want to minimize the horizontal padding of a textbox. Using snoop I found that the textbox consists of a multiple sub-controls. One of them is a TextBoxView with a margin of 2,0,2,0 The TextBoxView is an internal wpf component and has no public API. How would you approach getting rid of the "internal padding"?? 回答1: Set the outer margin to -2,0,-2,0 to compensate for the padding. 回答2: I created a custom control that removes that internal padding. public class MyTextBox :
