电脑慢是怎么回事
中毒,C盘临时文件和cooick文件多.电脑硬件老化.CPU桂膏干了.建议你一个礼拜清除一次垃圾,每一年都要清理一下机箱里面的灰尘,和重新给CPU涂一些桂膏上去.
天天炫斗28级已经升级这么慢了以后该怎么办啊
天天炫斗经验主要来源于心动挑战、经验副本、主线任务、支线任务和日常任务。
【爱心】
首先我们来了解下爱心的使用和获得,有些人不知道爱心拿来是干嘛的。这里我给大家科普下,除了每天系统给的爱心,还可以通过好友的赠送来获得。爱心的用途在于【心动挑战】和【爱心祈福】
【心动挑战】每天可免费挑战5次,还可用钻石获得额外的任务次数。【心动挑战】显示一颗爱心,则表示需要一颗,以此类推。同时心数越高的任务,获得的经验也越多。
【爱心祈福】则可以通过大转盘抽奖的方式,消耗爱心来抽取其它奖品。
这里特别提醒一下,除了爱心祈福,大家还可以用【钻石祈福】,钻石祈福的奖品更大哦!
【经验副本】
角色升级,需要经验。而经验副本,绝对是主要的经验来源途径(图3)。
经验副本的生成条件:1级经验副本要求等级:10级。 2级经验副本要求等级:18级。3级经验副本要求等级:30级。 4级经验副本要求等级:40级。经验副本凌晨0点重置。
我们需要注意的是,经验副本一旦达到下一级别要求,副本次数会重置。如等级10,1级经验副本没刷完,18级后就会重置成2级经验副本。这就会浪费了非常多的经验,要知道一次经验副本差不多可以升1级的,所以进入游戏后,要优先挑选经验副本去玩。
最后,经验副本的【付费翻牌】是需要钻石来翻的,很多人不舍得那10来个钻石,舍不得翻这是大错特错的,你要知道下面的付费翻牌,所获得的经验,差不多是免费翻牌的两倍。也就是出几个钻石,就换来超级多的经验,升级就更快了。
【任务】
任务还有分为主线和支线任务(图4),当级别到达一定级别的时候会解锁一个新副本,副本会生成一个主线和两个支线任务。分解是普通、精英、挑战级别的副本,完成普通级别后才能进入精英级,完成精英级后才能进入挑战级。完成任务后可分别获得获得金币、经验、装备和装备源力。
建议根据自己当前的需要,选择对应的任务进行游戏。例如需要角色升级,那么就做经验必须多的任务。需要金币的,就做金币比较多的任务。需要武器碎片的,就做武器碎片的任务。
还有【日常任务】,日常任务相对获得的经验比较少,但是胜在每天都能完成积少成多。建议一定要做,例如日常任务有一个是【强化武器】10次,这个一开始就要去做,因为武器强化了,战力就提升了。这样子打怪的时候就不容易死,否则打不过关是一件很痛苦的事情,白白浪费时间。如果强化所需的金币不够,就小额买一点,玩游戏更爽,小额消费一下,我认为没有什么不妥。一个盒饭的钱,就可以在游戏里面玩得超时爽快。实在不想花钱的,也可以每天固定时间去通过打招财猫等世界BOSS获得。
以上介绍提供参考,希望对大家有所帮助谢谢。

在网吧遇到一些电脑问题了。请教一下。
1、开机按F8不动到高级选项出现在松手,选“最近一次的正确配置”回车修复。
2、开机按F8进入安全模式后在退出,选重启或关机在开机,就可以进入正常模式(修复注册表)。
3、如果故障依旧,请你用系统自带的系统还原,还原到你没有出现这次故障的时候修复(如果正常模式恢复失败,请开机按F8进入到安全模式中使用系统还原)。
4、如果故障依旧,使用系统盘修复,打开命令提示符输入SFC /SCANNOW 回车(SFC和/之间有一个空格),插入原装系统盘修复系统,系统会自动对比修复的。
5、如果故障依旧,在BIOS中设置光驱为第一启动设备插入系统安装盘按R键选择“修复安装”即可。
6、如果故障依旧,建议重装操作系统。
如果实在不行,建议选择修复安装,这样即修复了系统,又可使C盘的程序和文件不受损失。

白求恩的简介,英文的..!!急!!
Norman Bethune
Bethune, a national hero in China, was born in Gravenhurst, Ontario, Canada. He was the son of a Presbyterian minister Rev. Malcolm Bethune and his wife Elizabeth. His grandfather, Norman Bethune Sr. was also a noted Canadian physician and co-founder in the 1850s of Trinity College Medical School which was later absorbed by the University of Toronto. Two other ancestors of note were his great grandfather Angus Bethune who rose to become partner in the fur trading North West Company and the grand patriarch of the family, Rev. John Bethune, who came over to North America from Scotland in the 1770s. In North Carolina Rev. John Bethune found that he opposed American independence from Britain. This led to his departure for Canada where as a United Empire Loyalist he founded the first Presbyterian church of Montreal and subsequently of Upper Canada, at Williamstown near Cornwall.
He attended Owen Sound Collegiate in Owen Sound, Ontario, now known as Owen Sound Collegiate And Vocational Institute. He graduated from OSCVI in 1907, four years ahead of William Avery “Billy” Bishop. Both names are inscribed on the School’s Great War Memorial.
The young Norman Bethune enrolled at the University of Toronto in September 1909 and then worked for a year as a labourer-teacher with Frontier College. In 1915 he joined the No.2 Field Ambulance in France, where, as a stretcher-bearer, he was hit by shrapnel and spent three months recovering in an English hospital. The injury allowed him to return to Toronto to complete an accelerated medical degree by December 1916. Bethune’s first private medical practice was in Detroit, Michigan where he contracted tuberculosis from working with the poor. He sought treatment at the Trudeau Sanatorium in upstate New York, and believing he was dying, insisted upon radical thoracic surgery which saved his life. Recuperated, he joined the famous Edward Archibald at McGill University in Montreal. He perfected his skills in thoracic surgery at the Royal Victoria Hospital where he also taught. Bethune was an early proponent of universal health care, the success of which he observed during a visit to the Soviet Union. As a concerned doctor in Montreal during the dirty thirties, Bethune frequently sought out the poor and gave them free medical care.
Fearing the onslaught of fascism, he travelled to Spain (1936-1937) where he assisted the Republicans in the Spanish Civil War and to China (1938-1939), aiding the Chinese in their war with Japan, in both cases performing battlefield surgical operations on war casualties.
Bethune’s work in Spain in developing mobile medical units was the model for the later development of Mobile Army Surgical Hospital (MASH) units. The need to provide blood transfusions in a battlefield led him to develop the first practical method for transporting blood. In China, he worked with carpenters and blacksmiths to forge new surgical tools, and established training for doctors, nurses and orderlies. He redesigned packing containers to serve as operating tables. He treated wounded Japanese prisoners.
Bethune died on November 12, 1939, of blood poisoning from a cut he received when performing surgery, while with the Communist Party of China’s Eighth Route Army in the midst of the Second Sino-Japanese War.
Informix常用命令
Informix常用命令的用法说明
语法 oninit [-s] [-i] [-p] [-y]
oninit???将系统从off-line模式变为on-line模式
oninit -s ? 将系统从off-line模式变为quiescent模式
oninit -i ? 初始化系统
oninit -p ? 在共享内存初始化时,不搜索,删除临时表
oninit -y ? 对提示自动回答yes
oninit -v 加入这个选项显示oninit处理过程
oninit– 键入此命令可以获得使用帮助
oninit命令用来改变系统的运行模式。其中-i选项用于初始化系统的root dbspace。注意,root-dbspace一旦被初始化,则等于整个数据库系统被初始化。
如果用户希望在计算机启动时自动自动启动动态服务器系统,请在系统初启文件(在许多UNIX系统中为/etc/rc)中加入oninit命令(不加任何选项)。

用FileUpload控件怎么实现多图片上传
FileUpload实现单图片上传,如果想多图片上传,你试试这个:
<tr>
<td align=”right” valign=”top”>
试卷照片:
</td>
<td align=”left”>
<div id=”_container”>
<input id=”File1″ type=”file” name=”File” runat=”server” size=”10″ />
</div>
</td>
<td align=”left” valign=”bottom”>
<input type=”button” value=”添加” onclick=”addFile()” />
</td>
</tr>
addFile()源码:
//多文件上传,动态生成多个上传控件
function addFile() {
var div = document.createElement(“div”);
var f = document.createElement(“input”);
f.setAttribute(“type”, “file”);
f.setAttribute(“name”, “file”);
f.setAttribute(“size”, “10”);
div.appendChild(f);
document.getElementById(“_container”).appendChild(div);
}
后台页面调用:
#region 上传添加图片的方法
/// <summary>
/// 上传添加图片的方法
/// </summary>
/// <param name=”nId”>关联id</param>
private static void UploadAndAddPicTures(int nId)
{
LMS.BLL.TRAIN_Pictrue PictrueBLL = new LMS.BLL.TRAIN_Pictrue();
List<LMS.Model.TRAIN_Pictrue> list = new List<LMS.Model.TRAIN_Pictrue>();
//遍历File表单元素
HttpFileCollection files = HttpContext.Current.Request.Files;
for (int iFile = 0; iFile < files.Count; iFile++)
{
//检查文件扩展名字
HttpPostedFile postedFile = files[iFile];
string fileName;
fileName = System.IO.Path.GetFileName(postedFile.FileName);
if (fileName.ToLower() != “”)
{
LMS.Model.TRAIN_Pictrue Pictrue = new LMS.Model.TRAIN_Pictrue();
string scurTypeName = fileName.Substring(fileName.LastIndexOf(“.”));
//初始化原图物理路径
string sGuid_phy = Guid.NewGuid().ToString();
string sUrl_phy = ConfigurationManager.AppSettings[“PhysicsObjectPath”].ToString() + sGuid_phy + scurTypeName;
//初始化缩略图物理路径
string sGuid_web = Guid.NewGuid().ToString();
string sUrl_web = ConfigurationManager.AppSettings[“PhysicsObjectPath”].ToString() + sGuid_web + scurTypeName;
postedFile.SaveAs(sUrl_phy);//保存原图
PTImage.ZoomAuto(postedFile, sUrl_web, 100, 100, “”, “”);//生成缩略图,并保存
//保存原图虚拟路径到数据库

如何使用STM32CubeMX配置ETH
展开全部
具体配置过程:
1、打开STM32CubeMX,并选择好相应的芯片。文中的芯片为STM32F207VCT6,选择后如下图:
2、配置RCC时钟、ETH、PA8以及使能LWIP;
由于此处我们的开发板硬件上为RMII方式,因此选择ETH-RMII,若有同志的开发板为MII方式,请参考MII的配置方法,此处只针对RMII;
RCC选择外部时钟源,另外勾选MCO1,软件会自动将PA8配置为MCO1模式,该引脚对于RMII方式很重要,用于为PHY芯片提供50MHz时钟;
使能LWIP;
3、时钟树的相关配置,必须保证MCO1输出为50Mhz,如果这个频率不对会导致PHY芯片无法工作;
我这里因为芯片为207VCT6,为了使MCO1输出为50Mhz,做了PLL倍频参数的一些调整,总体如下:(同志们配置时可根据自己的芯片灵活配置,但需保证MCO1的输出为50Mhz)
4、ETH、LWIP、RCC相关参数设置;
至此,比较重要的都在前面了,但是还有一点仍需要注意,即PA8引脚输出速度,几次不成功都是因为这个引脚没注意。
后续的参数设置可以根据同志们自己的需求分别设置,这里给出我的设置供参考;
ETH参数保持默认,但中断勾选一下;
LWIP参数设置如下:(因为我这里是配置UDP服务器,IP选择静态分配)
5、生成工程,做最后的函数修改;
给生成的工程添加UDP服务器的初始化以及端口绑定等相关函数;
我这里直接将之前的官方例程中的UDP服务器文件加进来,如下:
之后将.c文件添加到用户程序,主函数添加Udp的.h头文件;如下:(udp文件的具体内容在后面给出)
6、主函数还需要添加一下几个函数,在这里不对函数作用及实现原理讲解,仅做添加说明。
附:udp_echoserver相关文件内容(该文件为官方的示例程序,版权归官方,此处做转载)
udp_echoserver.c的内容如下:
/* Includes ——————————————————————*/
#include “main.h”
#include “lwip/pbuf.h”
#include “lwip/udp.h”
#include “lwip/tcp.h”

void udp_echoserver_receive_callback(void *arg, struct udp_pcb *upcb, struct pbuf *p, const ip_addr_t *addr, u16_t port);
/* Private functions ———————————————————*/
/**

*/
void udp_echoserver_init(void)
{
struct udp_pcb *upcb;
err_t err;
/* Create a new UDP control block */
upcb = udp_new();
if (upcb)
{
/* Bind the upcb to the UDP_PORT port */
/* Using IP_ADDR_ANY allow the upcb to be used by any local interface */
err = udp_bind(upcb, IP_ADDR_ANY, UDP_SERVER_PORT);
if(err == ERR_OK)
{
/* Set a receive callback for the upcb */
udp_recv(upcb, udp_echoserver_receive_callback, NULL);
}
}
}
/**
* @brief This function is called when an UDP datagrm has been received on the port UDP_PORT.
* @param arg user supplied argument (udp_pcb.recv_arg)
* @param pcb the udp_pcb which received data
* @param p the packet buffer that was received
* @param addr the remote IP address from which the packet was received

* @retval None
*/
void udp_echoserver_receive_callback(void *arg, struct udp_pcb *upcb, struct pbuf *p, const ip_addr_t *addr, u16_t port)
{
/* Connect to the remote client */
udp_connect(upcb, addr, UDP_CLIENT_PORT);
/* Tell the client that we have accepted it */
udp_send(upcb, p);
/* free the UDP connection, so we can accept new clients */
udp_disconnect(upcb);
/* Free the p buffer */
pbuf_free(p);
}
udp_echoserver.h的内容如下:
#ifndef __ECHO_H__
#define __ECHO_H__
void udp_echoserver_init(void);
#endif /* __MINIMAL_ECHO_H */
7、至此,所有的工作完成,编译工程,下载至开发板。由于udp_echoserver中绑定的端口号为7,这里我们通过测试工具测试网络的功能,
