how to insert part of image into picturebox?

由 徘徊边缘 提交于 2019-12-07 22:32:38
问题 I'm not really sure if it is possible to insert a part of image into picturebox, but I would like to create an image 500*500 pixels in size and then use the parts of it as small connectable 50*50 pieces by setting the location of image inside the pictureboxes... Is anything similar possible through use of graphics? I'm not very familiar with it... (I am talking about C# forms application...) 回答1: After some time of searching and few personal attempts I have found a solution, this isn't my own

twisted location header redirect

由 笑着哭i 提交于 2019-12-07 21:30:50
问题 From the render_GET method of a Resource in twisted , is it possible to redirect to a different url entirely (hosted elsewhere) request.redirect(url) doesn't appear to do anything, and neither does twisted.web.util.Redirect The equivalent in php would be, header('location:'.$url); EDIT this is the code I'm running from twisted.web import server, resource from twisted.internet import reactor class Simple(resource.Resource): isLeaf = True def render_GET(self, request): request.redirect("www

Make a timer/handler to get current location every 5 seconds in a fragment?

由 无人久伴 提交于 2019-12-07 20:06:54
问题 I have this class to get actual location , the second point (marker) is set by another fragment. I really need to update my location automatically instead clicking the google button for it. How can I make this? What is the best way to make this? I don´t figure out where to place it. I was thinking in placing a timer or something like that. I would prefer to make it with just google maps functionalities. Timer timer = new Timer(); timer.schedule(new TimerTask() { public void run() { } }, 0,

Get current position with GPS AND WIFI

由 懵懂的女人 提交于 2019-12-07 17:58:30
问题 I'm currently using GPS only to get current location of the user to return certain results. As in Belgium, if you're inside, most of the time you can't get GPS-connection. So I want to get the current location with the wifi-connection. I've found this example: get the current location (gps/wifi) But I'm not sure which lines tell the device which connection to choose. I'm guessing it's this one: String provider = myLocationManager.getBestProvider(criteria,true); That I've to add to my code.

Alert when two users/friends are near to each other - Android Proximity

由 北城余情 提交于 2019-12-07 16:30:51
问题 I tried searching but i couldn't find anything. My Question is " How can i alert 2 or more users if they are nearby each other? " in android using Geo-fencing or something else. Say, If a UserA is in football ground and UserB walking nearby that football ground. Then UserA and UserB automatically gets notification that UserA/UserB are somewhere nearby. 回答1: Finally after spending a couple of hours thinking, I thought a better way to do this: Setup a database (MySQL,SQL etc) in your server

How to get the most accurate possible speed from GPS in Android

由 妖精的绣舞 提交于 2019-12-07 13:08:46
问题 How can I get an accurate speed from GPS in Android? Yes, I am aware of the location.getSpeed() method in the Location class. Problem is, the default implementation returns 0.0 as speed: apparently that is the default behavior. What I'm currently doing, is as follows, consider location objects a and b, where a is taken first, b later: a.distanceTo(b)/(b.getTime()-a.getTime()); (simplified for readability, original code deals with history ArrayList ) Problem is that this is somewhat inaccurate

nginx静态资源服务器简单配置

由 拥有回忆 提交于 2019-12-07 12:52:02
传统的web项目，一般都将静态资源存放在 webroot的目录下，这样做很方便获取静态资源，但是如果说web项目很大，用户很多，静态资源也很多时，服务器的性能 或许就会很低下了。这种情况下一般都会需要一个静态资源的服务器。 搭建nginx服务器首先得安装nginx服务，关于nginx服务的安装可以参考我的另一篇博客 《nginx服务安装》 这里直接介绍静态服务器的配置 进入nginx安装目录的conf目录下，修改nginx.conf文件，在一个server{}中添加 一个location 部分配置代码如下 root @ubuntu :/usr/local/nginx/conf # vi nginx.conf server { listen 80 ; server_name localhost; location / { root html; index index.html index.htm; } location /image/ { root /usr/local/myImage/; autoindex on; } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 2 3 4 5 6 7 8 9 10 11 12 13 14 从上面的配置可以看出来 端口为80，server_name为localhost（写ip地址也可以） location /image
