1. switch怎么开机
1
首先找到switch主机屏幕上方的电源键按钮并按住。
2. 我有两张Winform主窗体的背景图片，在运行时怎么样切换背景图片，就像换皮肤一样
C#winform中给mdi主窗体添加自定义背景图片2011-07-06 16:05修改MDI窗口的主背景是MS不推荐的，但如果你需要可以使用下面的方法：
1——
原理：
MDI窗口有一个叫MdiClient的窗口对象作为主背景窗口，要修改MDI窗口的背景就是修改该MdiClient对象的背景
2——
关键：
如何获得MdiClient对象
3——
方法：
MdiClient是作为MDI窗口的一个ChildControl的形式存在的，因此我们可以通过遍历MDI窗口的Controls对象集来获得
4——
示例：
下面的代码把MDI窗口的主背景修改为兰色（如果你有特别的处理请作相应的处理）
private System.Windows.Forms.MdiClient m_MdiClient;
public Form1()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent();
//
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
int iCnt=this.Controls.Count;
for(int i=0;i<iCnt;i++)
{
if(this.Controls[i].GetType().ToString()=="System.Windows.Forms.MdiClient")
{
this.m_MdiClient=(System.Windows.Forms.MdiClient)this.Controls[i];
break;
}
}
this.m_MdiClient.BackColor=System.Drawing.Color.Blue;
}
具体的应用中，可以参考上面的代码把背景修改为其他的颜色、用图片平铺、拉伸等，就象通过代码修改非MDI窗口的背景一样。
另外，具体应用时，可能要考虑把这些东西放置到Paint或erasebkground等事件。
c# 2.0 给MDI主窗口添加背景最简单的办法，4句代码搞定
一、将MDI主窗口的IsMdiContainer设为 False，将背景图片放到资源文件中，资源名为BackgroundImage
二、在MDI主窗口的构造函数中InitializeComponent();之后加下面4行代码
MdiClient m = new MdiClient();
this.Controls.Add( m );
m.Dock = DockStyle.Fill;
m.BackgroundImage = Properties.Resources.BackgroundImage ;

3. ios中uiswitch超出的背景颜色怎样处理
1、创建一个empty（空的）工程项目，新建一个UIViewController；
2、选中工程，右键-New File…选择“Cocoa Touch Class”-Next，给个合理的名称ViewController，再Next完成；
3、在AppDelegate.m文件包含#import "ViewController.h"；
4、初始化创建ViewController的视图控制器，并用导航栏控制器包含。将之设置为根视图控制器。
创建添加UISwitch对象
1、创建并初始化一个UISwitch，宽高是固定的，不为0就可以显示；
3、设置背景颜色可以看到效果;
4、将UISwitch添加到self.view中。
设置UISwitch的属性
1、onTintColor设置开启颜色；
2、onImage设置开启图片；
3、tintColor设置正常关闭颜色；
4、offImage设置关闭图片；
5、thumbTintColor设置圆形按钮颜色；
代码设置开启/关闭状态
//设置YES或NO，是否使用animated动画效果：
[mySwitch setOn:YES animated:YES];
获取UISwitch的开启/关闭状态
1、获取对象的isOn属性，默认是关闭状态；
2、如果isOn==YES则是开启状态，如果isOn==NO则是关闭状态。
添加动作事件（完成）
可以选择id类也可以选择UISwitch类，如果是id类型，则要转换成UISwitch类型：UISwitch *mySwitch = (UISwitch *)sender。
4. android 自定义switch样式
修改后的MySwitch控件接口基本与原Switch控件一致，并且除了可支持所有SDK外，增加了2项小功能：
1. 支持用Track背景图片的方式代替Texton Textoff等文字方式表现开关状态
2.支持调整控制Switch的高度
下面贴出Switch修改的关键代码：
/**
* <p>
* modified from android SDK 14(4.0) android.widget.Switch.
* <br/>
* <strong>new feature: </strong>
* <ol>
* <li>support SDK 1 or higher. </li>
* <li>you can use track drawable instead of text to display the changes of off-on state!</li>
* <li>you can control the Switch minimum height. </li>
* </ol>
* </p>
*
* @see {@link Switch}
* @author Wison
*/
public class MySwitch extends CompoundButton {
// Support track drawable instead of text
private Drawable mTrackOnDrawable;
private Drawable mTrackOffDrawable;
// Support minimum height
private int mSwitchMinHeight;
/**

* overriding specific style attributes as requested.
*
* @param context The Context that will determine this widget's theming.
* @param attrs Specification of attributes that should deviate from the default styling.

5. C#中如何单击按钮变换背景图片
这么多个重复的代码。。
个人建议
1、做个函数，里面禁掉所有panel的visible.
再判断if (comboBox1.Text == "1")就显示panel1
或者换为switch case语句更清楚。
2、更简洁的方式。一个string数组，存好12张图的路径
就用一个panel
再判断if (comboBox1.Text == "1")就显示panel1
或者换为switch case语句更清楚。
就设置panel1.BackgroundImage = Image.FromFile(数组元素)就一切搞掂。
有问题直接找我。
6. 如何修改NSview的背景颜色
最简单的方法：打开图片---选择---色彩范围，点击绿色（可以按住SHIFT键，在绿色上反复点击，直到绿色全部被选中），然后在选区填充白色。选区的精度可以用色彩范围里面的逗容差地来调节
