C#的winform程序下如何实现文本编辑框(TextBox)的Hint提示文字效果
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SendMessage(IntPtr hWnd, int msg, int wParam, [MarshalAs(UnmanagedType.LPWStr)] string lParam);
public static void SetHintText(Control control, string text)
{
SendMessage(control.Handle, 0x1501, 0, text);
}
