VB制作软键盘

用API keybd_event来模拟按键过程，但是Ctrl+Alt+Del不能模拟，前面已经定义了各个按键的值，需要按什么键替换成对应的值就行了，由于是模拟键盘按键，所以按键发送的对象是当前激活的窗口。

android 如何让软键盘自动弹出？

可以通过下面的代码来实现Android自动弹出软键盘：

edittext.requestFocus(); //edittext是一个EditText控件

Timer timer = new Timer(); //设置定时器

timer.schedule(new TimerTask() {

@Override

public void run() { //弹出软键盘的代码

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

imm.showSoftInput(edittext, InputMethodManager.RESULT_SHOWN);

imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

}

}, 300); //设置300毫秒的时长

说明：同样是在写Techo Lite时遇到的问题。希望程序可以自动弹出软键盘，可是尝试了各种办法都没有效果。问题的原因似乎是必须等待UI绘制完成后弹出软键盘的代码才会有效。于是就采用了上面的方法。需要注意的是，在此之前必须让edittext获取焦点，不然也是无效的。

请问在网页代码中的“打钩”代码是什么？

步骤如下：

1.插入一个文字框，在框内写好文章;

2.勾选编辑器左下角的“源代码”，在源代码中找出字段，在table之后空出一个半角空格，填写以下代码：

background=图片的网络地址 style="backgroundrepeat:repeat-no; 50% 50%"
