panel的滚动条

panel的水平滚动条如何禁用，而让垂直滚动条照常

[王集鹄]

参考如下代码：

using System.Runtime.InteropServices;

[DllImport("user32.dll")]
public static extern int ShowScrollBar(IntPtr hWnd, int iBar, int bShow);

const int SB_HORZ = 0;
const int SB_VERT = 1;

public class SubWindow : NativeWindow
{
    protected override void WndProc(ref Message m)
    {
        ShowScrollBar(m.HWnd, SB_HORZ, 0);
        base.WndProc(ref m);
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    SubWindow vSubWindow = new SubWindow();
    vSubWindow.AssignHandle(panel1.Handle);
}
