由 六月ゝ 毕业季﹏ 提交于 2019-12-17 18:09:08
问题 I'm trying to move the control named pictureBox1 by dragging it around. The problem is, when it moves, it keeps moving from a location to another location around the mouse, but it does follow it... This is my code. and I would really appreciate it if you could help me public partial class Form1 : Form { public Form1() { InitializeComponent(); } bool selected = false; private void pictureBox1_MouseDown(object sender, MouseEventArgs e) { selected = true; } private void pictureBox1_MouseMove

Using orientation sensor to point towards a specific location

由 拥有回忆 提交于 2019-12-17 17:58:29
问题 I'm trying to implement an arrow that uses the orientation sensor in order to point towards a specific location. Google Places implements this arrow in a ListView for each place it finds. I've managed to get the azimuth, but given a location, I don't know how to proceed to calculate the angle I need. Moreover, I need to make the conversions from real north and magnetic north. Does anybody have an example of such implementation? Thanks in advance. 回答1: I solved it. float azimuth = // get

C# - How do I access the WLAN signal strength and others?

由 故事扮演 提交于 2019-12-17 17:58:15
问题 Many scientists have published papers documenting how devices connected via WLAN can be tracked by measuring its Signal Strength, Time Of Arrival, Round Trip Time, etc. Any idea how I can access these values in Windows using any .NET API? Or do you know of software SDKs already available for location tracking? 回答1: hello for WIndows 7 this is a good code wich can detect all AP with MAC adress RSSI SSID : using System; using System.Collections.Generic; using System.ComponentModel; using System

How to set fake GPS location on IOS real device

由 元气小坏坏 提交于 2019-12-17 17:44:08
问题 Currently I have to test app and set the different fake GPS locations on real IOS 7 devices. On Android I use 'My Fake Location'. Unfortunately, I didn't find the same app for IOS 7. Any ideas to solve my problem? 回答1: Of course ios7 prohibits creating fake locations on real device. For testing purpose there are two approches: 1) while device is connected to xcode, use the simulator and let it play a gpx track. 2) for real world testing, not connected to simu, one possibility is that your app

How to calculate distance from different markers in a map and then pick up the least one

由 醉酒当歌 提交于 2019-12-17 15:46:16
问题 I have to get distance from different markers on the map to the current location of the device and the pick up the shortest one. I have the lat and long for the markers and the current location lat and long can be fetched dynamically. Suppose I have 5 markers on the map, Bangalore (Lat : 12.971599, Long : 77.594563), Delhi (Lat : 28.635308, Long : 77.224960), Mumbai (Lat : 19.075984, Long : 72.877656), Chennai (Lat : 13.052414, Long : 80.250825), Kolkata (Lat : 22.572646, Long : 88.363895).

Fastest way to detect external URLs

由 只谈情不闲聊 提交于 2019-12-17 15:37:14
问题 What's the fastest method to detect if foo='http://john.doe' is an external url (in comparsion to window.location.href )? 回答1: I know the regex version has already been accepted but I would bet this is "faster" than doing that complex of a regex. String.replace is quite fast. var isExternal = function(url) { var domain = function(url) { return url.replace('http://','').replace('https://','').split('/')[0]; }; return domain(location.href) !== domain(url); } Update I decided to do a little more

Check if location services are enabled

由 有些话、适合烂在心里 提交于 2019-12-17 15:21:41
问题 I've been doing some research about CoreLocation. Recently, I encountered a problem that has been covered elsewhere, but in Objective C, and for iOS 8. I feel kinda silly asking this, but how can you check if location services are enabled using swift, on iOS 9? On iOS 7 (and maybe 8?) you could use locationServicesEnabled() , but that doesn't appear to be working when compiling for iOS 9. So how would I accomplish this? Thanks! 回答1: Add the CLLocationManagerDelegate to your class inheritance

iOS background application network access

由 让人想犯罪 __ 提交于 2019-12-17 09:47:56
问题 I have an application that requires location tracking and I think it fits squarely within one of the allowable background models. However, I need to post to a network service when there are significant changes of location. I've seen write-ups that state network access is prohibited in background processing, but I didn't read that in Apple's docs. Does anyone know if it's kosher (wrt Apple policies) to make occasional and very quick network updates in a background process? 回答1: Good point,
