无法打开client.dbfs

微信系统这个段子服务无法启动怎么办？方法一，一鼠标右键点击计算机选择管理。二，在计算机管理页面中点击本地用户合组，点击用户。 三，在用户右侧的界面中，双界的 minster 选择在其属性界面将账户已经用头像取消勾选，点击确定。方法二，若按照上面的进行操作之后还是未能将问题所排除，则需要进入到注册表编辑器中进行修改。 一，按 win 加二，打开运行窗口，输入 rabbit， 点击确定。二，在打开的注册表编辑器窗口中依次点击打开和下划线 local 下划线 washing system current controls its services。 三，在 services 里面找到 d h c p， 鼠标右键点击选择权限。 四，在 dhcp 的权限窗口中点击添加，然后点击高级。五，进入选择用户和主页面，点击右侧的立即查找，找到 network versus 并选中，然后点击确定。 六，随后返回到了 v h c p 的权限的窗口中，选中 netword service， 并将完全控制里面的允许勾选，点击应用并即可。

啊，我没有快乐了啊，快乐。

打开应用程序或虚拟及安装新的系统等等，会出现该内存不能为 reton 的提示。为什么会出现提示呢？首先快捷键 wing 加二，弹出运行，输入 cnd 后点击确定按钮，进入 dos 命令界面，在命令提示符下输入， fore in winter system 三二 dll du raxper 三十二 excs 一、输好代码后，敲击回车键，系统开始重新注册 dll 文件，这需要稍微等待一段时间，等 dll 文件重新注册完成后，内存不能为 read 或 written 的问题就解决了，你学会了吗？

win 七系统电脑无法上网，启动 d h c p 服务的时候出现错误五，拒绝访问。 win 七系统下面的小电脑出现了一个感叹号， 无法连接网络，我们打开网络连接，查看一下网络连接状态，这里都是显示无英特访问权限，点击详细信息，看到是没有正确获取路由器 ip 地址， 像这种情况一般是 dhcp 服务运行不正常，这时候我们就去查看一下这个服务状态是什么样子的。首先选择我的电脑右键选择管理，选择服务和 应用程序，选择服务就进入系统服务管理界面，也可以键盘按 win 加 r 调出运行框，在运行框输入 s e r v i c e s 点 m s c 一样可以调出服务管理框。在服务框里找到 dhcp 服务， 左键双击此服务，调出 d h c p 服务的属性，点击启动， 提示 windows 无法启动 dhcp 服务。错误五，拒绝访问。出现这个错误其实就是注册表没有被赋予作为服务 登录的账号的操作权限，如果按照视频的方法赋予权限还是出现这个错误，那就只有去注册表修改权限。这时候我们就要调出命令提示服务运行框， 输入下面的两行命令，把这两行命令分别输入好后，按确定 两行命令正确输入完成，按确定后都会提示命令成功，完成命令操作完之后重新启动电脑。 一般来说，重新启动电脑之后就可以正常启动 d h c p 服务了。欢迎评论区留言讨论，本期视频到此结束，拜拜！

打开 excel 时报文件已损坏，无法打开怎么办？同一个 excel 文件在一个电脑打开报错，而在其他电脑打开正常这个情况不一定是文件损坏，也可能是 excel 安全设置引起的。 可以尝试以下方法，启动 excel 程序或打开任意 excel 文件，点击左上角文件，再点击选项，在选项设置中点击信任中心，再点击信任中心设置按钮，找到受保护的视图设置取消，选中所有复选框， 再点击受信任位置，点击添加新位置，点浏览按钮，选择 excel 文件所在路径，以桌面为例，选择后点确定勾选信任此位置的子文件，加 之后依次点击确定。关闭选项菜单，然后重启 excel， 并打开一个文件进行测试。本方法只适合文件，并不是真损坏的场合，日常重要文件还是要注意保留多个备份。

但是 appadata 打不开了，有时候提示这个官网上很多更新是不需要重复更新的啊，具体需要更新什么呢？我都建议大家用 diapadata 这个软件，但是最近有小伙伴问我这个软件会打不开， 因为他毕竟不是系统自带的工具，然后也没有交过保护费，他非常容易被一键优化掉啊。这个时候提示已经很明白了，只需要右键点此电脑，点管理，选择服务，找到戴尔 clint management service， 把这个服务调成自动就可以了。 特殊声明一下，我是戴尔主题的主播，为自己的客户提供服务并寻找解决方案，给自己的用户做活体的说明书，不参与任何品牌斗争，自己做饭自己吃，干净又卫生，我可不想被禁言。

电脑的这个记录你会看吗？又记此电脑，点击管理，点击事件查看器 windows 日制，选中系统，然后在日制中找世界 id 为六零零五的日制，这就是你的开机时间记录， 同时一个六零零五的前面肯定会对应一个六零零六的关机记录，如果没有说明，要么你的电脑费用关机了，要么你的电脑开启了快速启动功能了。你学会了吗？关注我，带你了解更多电脑小知识！

hello， everybody i'm naking this feed i'm going to clear out enemies conceptions you might have on how to properly use the h to be climbed in dot net every now and then i'm going to use it in a video and there will be comment saying you should not be doing that that is not the best practice but the truth is all the suggestions they have are outdated advice that actually has bugs in them， and i have to remove those comments because i don't want people to see them and actually follow them so in this video we're gonna clear all that once and for all if you liked above content and you want to see more make you subscribe ring the similification bell and for more training check out nickchopsus com now just a quick reminder before i show you the code i want to let you know that we'll be running my two day in person workshop introduction to effective testing in c shop and dotnet in a few conferences this year that is ndc offload ndc sydney dotnet days in romania， ndc minnesota and n d c london and probably more after that but for now those are the days so if you want to spend a couple of days with me and set the right fundamentals for your testing practices， then check them down below， so let me show you what i have here？ so i have a project over here which has a weather forecast controller injecting the eye weather client and this service actually has a real client calling the open weather client from the open weather map api with a real api key which by the time you watch this video will be invalidated so don't even bother and very quickly what this does is i expose an end point that allows the users to specify the city， so i can say for example london here and i can get the weather as you can see i can get bunch of different things like time zone name id than the wind speed and that's the current weather and then like temperature in that's not far and height is it is it calvin well it's definitely a temperature and if i for example here say paris then i'm going to get the paris one in france and so on and so forth that's the main idea and the reason why i'm using that example is because this client is using an hdp client to call the open weather map api now what you can see？ here is me using a new htv client per request and then i'm using the using keywood because htp client is actually implementing the message in volker which is implementing eye disposable and people know that if there's an eye disposable， then you should dispose it well， this is not true with the actual client and if you're doing this， you will probably encounter at some point in if you're traffic increases socket exhaustion and thankfully， most people know that and the fix for that is fairly easy their commendation that people have is to actually reuse the hdb client and that is correct you can go ahead and say privately， the only htb client and have your htb client be initialized here and i can copy that instantiation， actually， exactly as it is and then if i do that and i use that htb client over here and i comment that out then i don't need this either then this will work fine and because my code registers that open weather client as a singleton it is the same age to be client instance that's going to be reused not only preventing us from getting socket exhaustion， but actually offering better performance in fact you can see i have fifteen mill seconds here well before i had more like forty and you might have seen this in a different iteration because if this client is actually transit on scoped you don't want to create a new client every time through the class then some people make a static red only client and then there we use that static lion， which will be the same instance no matter how many times you instantiate this class and this will also work and actually give you the exact same benefits every single time so if you're doing that you're on the right track however， what most people don't know is that with this approach of a singleton edge to be client your code is suffering from a dns issue because if the dnsdtl is expired and that the main name now points to a new ip， your code will never know until it restarts because there is no logic by default in the htv， client to handle that what you could do to handle that is something like this？ you can have a new socket h to be handler and if you go ahead and you set the pooled connection lifetime property then you can set that to a valuable reflex dna strangers i can say like for minute one and this will actually solve the problem if you want to deal with it in a singleton fashion， however this is still not the recommended and best way to go about it what you want to do instead is use the ihdp client factory and that is the best way you can solve this problem for a few reasons， which i'm going to explain now so how do you use that there's actually a few ways you can do this？ but i'm going to show you what i think is the simplest way by default and all you need to say is in your program cs or your startup you want to say services dot add hdb client and in this case because i'm injecting it in the open weather client through the eye weather client registration i'm going to use the same services here so i'm going to say add an htp client in there and the great thing about this is because that client is specific to that thing i can say client dot and i can set all of my things like the base address for example in there so now it is preconfigured and i don't have to deal with it in here and now all i need to say is privately only hdb client and i can simply inject that here and now all i want to do use it there and then if i run this code， what i want to show？ you is that when i use a few brake points here is when i run this now and i hit the brake point you can see the client exists and it already has that open whether my up api url because it is that preconfigured h to be client and then it goes in here it gives me the response and i can see the response over there and this is very very efficient and the reason why this is the recommended way to do things is because what's going to happen is this htb client is actually transient but the handler behind the scenes which is what truly is doing the heavy lifting and is calling those apis is actually pulled and managed by the htv client factory and it gives you a client with a reused handler， which makes it very very efficient and it fixes that dns issue we can actually dive deeper in here in the program dot cs and show you exactly how that happens so what i have is the add h to be climbed and it's going to add it in the di and then we're gonna see as logging adds options as a bunch of stuff and then it reduces an htp message handler builder which is what is actually sending the request and then a default htp client factory and then it is wiring it up to return that over here and if we see what's in here， you will see that there's actually a bunch of stuff but the important thing is a great client method because that is what is giving you back that in uh to be client so what's happening is the code comes in here tries to find the handler from the cash handlers you can see them here the active handlers if it exists then it gives it back if it doesn't exist it put it in there and gives it back and you get back the htp message handler and then you're creating an htp client over here with that handler， which is marked as known disposable because we want to reuse the handlers because they're pulled and then we give the options back of the factory which is what that thing over here will effectively be so that is being respected as well and then we're returning that client and that is why this is the most efficient way to do this because the heavy object that is to be dodgy is actually cashed in memory pulled and reused and then the client itself， which is a very relatively thin object that just has instructions on how to use all its downstream components is just instantiated every time and if you want to dispose it you can and then there's a factory for the handler that is also registered over here and that's it and that is what's called in the htv client factory world the typed client you define that htv client to be resolved with a specific type however， it's not the only way you can do this？ you can also have for example a named client you can say that okay i don't define a type， but i say that this is my weather api client and you can do that too and the way this works is instead of actually injecting the client directly you can go ahead and say private reading only ihtplint factory and inject the htplint factory in here and then say client equals htplint factory that create client and pass down the name weather api and then that client can be used and actually i should definitely comment this thing out and with that thing commented out this absolutely find all the rules， the same rules will be respected and you just resolving it by name and you return the exact same thing are very efficient reused handlers and it's very nice if you want to have different clients in the same call and you don't want to inject three things things named htdb clients because it's not explicit which client you're getting so in that way， it's also a cleaner way to do things and actually another reason why htdb client factory is amazing is it's awesome integration with a library called poly， which in case you don't know i've talked about it in the past is where you're gonna spend most of your time if you're writing code that calls other apis， because you want those calls to be resilient and poly can give that resilience so please subscribe if you want to see more on how to use poly and how painless the process can be with that library but what do you think were you using those practices were you using the ihtv gland factory correctly were using a singleton htblind what was the approach you do were using leave a comment down below well， that's all i had for you for the video thank you very much for watching special thanks to my patreons for my kids with as possible if you want to support me really gonna find the link down below leave a like if you like this video subscribe more like this thing in the bell as well and i'll see you in the next video keep coding。

大家介绍一下这个模式啊，这个模式就相当于比如说你在房间里面有电脑，有无线路由器，也有这个功能的无线路由器啊，但是你的电脑没有无线网卡， 但这个房间呢，却可以搜到无线信号，而且这个无线信号你也知道密码，但是你手机也没有带，这种情况下载，只要路由器支持这个模式， 这个路由器就可以把远方的那个信号接收过来，然后再通过有线接入你的电脑，让你的电脑上网。选下一步， 当他拿这个设备去找信号，正在扫描，找到了我们制造的信号，连接无线密码，你知道这个无线密码， 让我下一步完成 点确定以后，你的电脑就可以上网了。 no， 现在数据都有了。 再说一句啊，这网卡的 ip 地址你要改回来哦，改回自动的，就还是前面那个地方， 全部改成自动才可以啊。全部改成自动才能上网啊，因为这个社会会给他分配地址，不需要你指定， 对吧？可以了。

有靓仔在问，为什么我的 vis 主策略打不开？哈哈，让我猜一下你是不是笔记本加 vis 家庭版。首先 vis 家庭版是没有配备主策略的，这有办法吗？有办法，桌面创建一个 tst 文本，输入这串代码， 接着把文件后最能改为 bat， 右键管理员运行完成后重启电脑，这样子就 ok 了。
