两个richtextboxes相同的滚动条 [英] same scroll bar for two richtextboxes

问题描述

有它有两个richtextboxes但只为一个共享的滚动条任何第三方工具。我需要实现两种不同语言的一些文本，但无论是文本框，滚动应在同一时间。

解决方案

 公开枚举ScrollBarType：UINT
    {
        SbHorz = 0，
        SbVert = 1，
        SbCtl = 2，
        SbBoth = 3
    }

    公共枚举消息：UINT
    {
        WM_VSCROLL = 0x0115
    }

    公共枚举ScrollBarCommands：UINT
    {
        SB_THUMBPOSITION = 4
    }

    [的DllImport（User32.dll中）]
    公共静态的extern INT GetScrollPos（IntPtr的的HWND，INT NBAR）;

    [的DllImport（User32.dll中）]
    公众的extern静态INT的SendMessage（IntPtr的的HWND，UINT味精，IntPtr的wParam中，IntPtr的lParam的）;
   //设置在richTextbox1双滚动和影响richTextbox2

    私人无效richTextBox1_VScroll（对象发件人，EventArgs的）
    {
        INT非营利组织= GetScrollPos（richTextBox1.Handle，（INT）ScrollBarType.SbVert）;
        非营利组织＆LT;＆LT = 16;
        UINT wParam参数=（UINT）ScrollBarCommands.SB_THUMBPOSITION | （UINT）非营利组织;
        SendMessage函数（richTextBox2.Handle，（INT）Message.WM_VSCROLL，新的IntPtr（wParam参数），新的IntPtr（0））;
    }
 

Is there any third party tool available which has two richtextboxes but only a shared scroll bar for both. I need to implement some text in two different languages but both the textboxes should scroll at the same time.

解决方案

    public enum ScrollBarType : uint
    {
        SbHorz = 0,
        SbVert = 1,
        SbCtl = 2,
        SbBoth = 3
    }

    public enum Message : uint
    {
        WM_VSCROLL = 0x0115
    }

    public enum ScrollBarCommands : uint
    {
        SB_THUMBPOSITION = 4
    }

    [DllImport("User32.dll")]
    public extern static int GetScrollPos(IntPtr hWnd, int nBar);

    [DllImport("User32.dll")]
    public extern static int SendMessage(IntPtr hWnd, uint msg, IntPtr wParam, IntPtr lParam);
   // Set the dual scrolling on the richTextbox1 and affects richTextbox2

    private void richTextBox1_VScroll(object sender, EventArgs e)
    {
        int nPos = GetScrollPos(richTextBox1.Handle, (int)ScrollBarType.SbVert); 
        nPos <<= 16;
        uint wParam = (uint)ScrollBarCommands.SB_THUMBPOSITION | (uint)nPos;
        SendMessage(richTextBox2.Handle, (int)Message.WM_VSCROLL, new IntPtr(wParam), new IntPtr(0));
    }
