richTextBox能高亮选择,光标仍在,没有光标闪烁
把重RichTextBox类
去除闪烁光标 http://msdn.microsoft.com/en-us/library/windows/desktop/ms648403%28v=vs.85%29.aspx
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices; namespace WindowsFormsApplication1
{
public class CustomRichTextBox: RichTextBox
{
[DllImport("user32.dll")]
static extern bool HideCaret(IntPtr hWnd); protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
HideCaret(Handle);
}
}
}
完整代码
CustomRichTextBox.CS
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices; namespace WindowsFormsApplication1
{
public class CustomRichTextBox : RichTextBox
{
[DllImport("user32.dll")]
static extern bool HideCaret(IntPtr hWnd); private bool bReadOnly = false;
public void SetReadMode()
{
ReadOnly = true;
bReadOnly = true;
} public void SetEditMode()
{
ReadOnly = false;
bReadOnly = false;
Focus();
} protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (bReadOnly)
HideCaret(Handle);
}
}
}
Form1.CS
using System;
using System.Collections.Generic; using System.Text;
using System.Windows.Forms; namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void button1_Click_1(object sender, EventArgs e)
{
CustomRichTextBox1.SetReadMode();
} private void button2_Click(object sender, EventArgs e)
{
CustomRichTextBox1.SetEditMode();
}
}
}
这种写法更彻底,不能选择
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices; namespace WindowsFormsApplication1
{ public class CustomRichTextBox : RichTextBox
{
private const int WM_SETFOCUS = 0x7;
private const int WM_LBUTTONDOWN = 0x201;
private const int WM_LBUTTONUP = 0x202;
private const int WM_LBUTTONDBLCLK = 0x203;
private const int WM_RBUTTONDOWN = 0x204;
private const int WM_RBUTTONUP = 0x205;
private const int WM_RBUTTONDBLCLK = 0x206;
private const int WM_KEYDOWN = 0x0100;
private const int WM_KEYUP = 0x0101; protected override void WndProc(ref Message m)
{
if (m.Msg == WM_SETFOCUS || m.Msg == WM_KEYDOWN || m.Msg == WM_KEYUP || m.Msg == WM_LBUTTONDOWN || m.Msg == WM_LBUTTONUP || m.Msg == WM_LBUTTONDBLCLK || m.Msg == WM_RBUTTONDOWN || m.Msg == WM_RBUTTONUP || m.Msg == WM_RBUTTONDBLCLK)
{
return;
}
base.WndProc(ref m);
}
}
}
