vb.net 组合键Ctrl+Enter怎样发送
看了很多这方便的解决方案，很多都是一大段代码，版本也有差别，既然有可能别人用得起我也用不起。

我用一种最简单的方法，只要思路对所有人都能用得起。
其实非常简单，就是获取键值，Ctrl+Enter的健值是10，是不是思路一下就通了。以下是源码：
Private Sub 聊天输入框_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles 聊天输入框.KeyPress
If Asc(e.KeyChar) = 发送快捷键值 Then
发送消息过程()
End If
End Sub

C#/VB.NET中模拟按键问题...为什么我运行无效??
一、模拟键盘操作
以下示例程序当点击button1按钮，模拟键盘在文本框textBox1中作输入操作，详细说明请参看MSDN帮助中的SendKeys类。
//事件完整代码
private void button1_Click(object sender, System.EventArgs e)
{
this.textBox1.Focus(); //先必须让文本框得到焦点，因为焦点在button1上
SendKeys.Send("^a"); //Ctrl+A
SendKeys.Send("{DEL}"); //Delete
SendKeys.Send("+(ec)"); //Shift+"ec"
SendKeys.Send("{ENTER}"); //Enter
SendKeys.Send("+ec"); //Shift+'e'＋'c'
SendKeys.Send("{ENTER}"); //Enter
SendKeys.Send("{h 10}"); //"hhhhhhhhhh"
SendKeys.Send("{ENTER}"); //Enter
SendKeys.Send("^%{DEL}"); //Alt+Ctrl+Del
}
二、模拟鼠标操作
以下示例程序当点击DBButton按钮，模拟鼠标双击窗体事件，并将鼠标向左上方移动10*10象素，其它操作类似。
//引入名字空间
using System.Runtime.InteropServices
//申明
[DllImport("user32")]
private static extern int mouse_event(int dwFlags,int dx,int dy, int cButtons, int dwExtraInfo);
const int MOUSEEVENTF_MOVE = 0x0001;
const int MOUSEEVENTF_LEFTDOWN = 0x0002;
const int MOUSEEVENTF_LEFTUP = 0x0004;
const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
const int MOUSEEVENTF_RIGHTUP = 0x0010;
const int MOUSEEVENTF_MIDDLEDOWN = 0x0020;
const int MOUSEEVENTF_MIDDLEUP = 0x0040;
const int MOUSEEVENTF_ABSOLUTE = 0x8000;
//事件完整代码
private void Form_DoubleClick(object sender, System.EventArgs e)
{
MessageBox.Show("你双击了屏幕");
}
private void DBButton_Click(object sender, System.EventArgs e)
{
mouse_event(MOUSEEVENTF_MOVE,-10,-10,0,0); //移动鼠标，否则事件发生在按钮上
Down,Up合为一次单击事件
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
}
VB.net 怎么制作按键连发功能
用API函数，以下代码Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As LongPrivate Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As LongPrivate Const WS_EX_LAYERED = H80000
Private Const GWL_EXSTYLE = (-20)
Private Const LWA_ALPHA = H2
Private Const LWA_COLORKEY = H1Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Const HWND_TOPMosT = -1
Private Const SWP_NOMOVE = H2
Private Const SWP_NosIZE = H1
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_KEYDOWN = H100
Const WM_KEYUP = H101
Const WM_CHAR = H102
Const VK_F1 = H70
Private Sub SendF1(hwnd) '调用这个过程即可对目标窗体发送F1键
Call PostMessage(hwnd, WM_KEYDOWN, VK_F1, 0)
Call PostMessage(hwnd, WM_KEYUP, VK_F1, 0)
End Sub这里是发送F1的实例，各个按键对应的虚拟键码，要到网上查
