键盘太脏了，洗洗吧。。。。。。。。。。。。一个一个扣啊，扣完洗啊。。。。。。。。
OK！搞定了，装上去试试，我勒个去，TAB坏了，咋办，用ENTER键当TAB用吧（实际不会这么做滴，呵呵）。好了，编码实现~~
首先我们讲的是winform程序，其他语言请勿对号入座，如有雷同，纯属巧合~
言归正传，ACTION~
其实监控键盘按键有两种方式：
1、重写ProcessDialogKey方法：
官方是这样解释ProcessDialogKey方法的
在消息预处理过程中调用此方法，以处理对话框字符，比如 Tab、Return、Esc 和箭头键。只有当 IsInputKey 方法指示控件未在处理该键时，才调用此方法。ProcessDialogKey 方法只是将字符发送给父级的 ProcessDialogKey 方法，或者，在该控件没有父级的情况下返回 false。Form 类重写此方法来执行对话框键的实际处理。仅当控件承载在 Windows 窗体应用程序中或充当 ActiveX 控件时，才调用此方法。
给继承者的说明 在派生类中重写 ProcessDialogKey 方法时，控件应返回 true 以指示它已处理该键。对于未由该控件处理的键，应返回调用基类的ProcessDialogChar 方法所得的结果。控件很少需要重写此方法（即使有的话）。
2、给控件增加KeyDown事件
代码如下：
1 protected override bool ProcessDialogKey(Keys keyData)
2 {
3 if (keyData == Keys.Return)
4 {
5 return base.ProcessDialogKey(Keys.Tab);
6 }
7 else
8 {
9 return base.ProcessDialogKey(keyData);
10 }
11 }
1 foreach(Control ct in groupBox1.Controls)
2 {
3 if ((ct is TextBox) || (ct is ComboBox))
4
5 {
6 ct.KeyDown += new System.Windows.Forms.KeyEventHandler(this.EnterKeyDown);
7 }
8 }
9
10
11 private void EnterKeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
12 {
13 if(e.KeyCode==Keys.Enter)
14 {
15 System.Windows.Forms.SendKeys.Send("{TAB}");
16 }
17 }
好了，这样我们就将回车键替换为了TAB，大家试试看，好用不。
最后附上keycode对应如下:
