coordinates

问题 I have seen lots of similar questions and those answers are what has gotten me this far. I have an application where all all object are created via DC, so they are all all drawn. (I have had much experience with sizers and 99% of the time sizers ROCK but in this case DC is the best answer.) So I want to have a tooltip for each element that is drawn and in the case the screen is refreshed and the element is drawn in a different location the tooltip should also move. My first attempt was with

问题 I am trying to parse the latitude and longitude from a json file onto Google map, as well as several other data into the information window. However i think might have screw up somewhere as when i tried to run the file, all i got was a blank screen. Can someone point out what i have done wrong. Any suggestion would be appreciated. I have made use of the earthquake data created by google as my reference point. > window.eqfeed_callback = function(results) { var bounds=new google.maps

问题 I have to send my GPS coordinates via SMS, How can I take the latitude and longitude values in SMS body? I tried something but i cant make it with +@id/lat or +String.valueOf(location.getLongitude() in intent.putExtra("sms_body","there would be latitude and longitude values.."); Here is the SmsActivity.java public class SmsActivity extends MainActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);

问题 I have a scroll viewer in my application that contains a canvas, in which I have a tree custom-drawn tree structure. I'm trying to get the position of a particular node element in the canvas relative to the scroll viewer (so I can scroll to it), but my attempts aren't working. I've tried using marker.TranslatePoint(new Point(0, 0), scrollViewer) (where marker is the element in the canvas), but this is just returning the position of the canvas, rather than the marker. Similarly, if I try

问题 I have the following problem: I'm writing a WinForms application with C# and i want to get the Screen - Coordinates of a part of a picture, in this case the top of this hand (marked by the red point). Does anybody know how i can do this programmaticaly? ("Koordinaten dieses Punktes" = Coordinates of this Point) EDIT: sry for confusing you, the picture above should only demonstrate my problem. The actual target of my program is to move the mouse-controlled-hand of a dart game to the right

问题 In my app whenever I place my second finger on the Screen. I should be able to show the center of the view shown in this post or below image at the point of touch of second finger. I am using the code shown below. The problem I face is the center of the mainarea is not at the second finger touch. public OnTouchListener mTouchlistener = new OnTouchListener() { @TargetApi(Build.VERSION_CODES.M) @Override public boolean onTouch(View v, MotionEvent event) { int pointerIndex = event.getActionIndex

问题 Unfortunately I'm still struggling a little with the new Kinect SDK 1.7. This problem is actually in the same context as "finding events via reflection c#": the Click event (however, it is not necessary for understanding this problem). My Problem is simple: if I have my right hand controlling the cursor (the "new" Kinect HandPointer) and it's in the upper left corner of the screen I want it to return the Coordinates (0,0). If the cursor is in the lower right corner the coordinates should be

问题 I made a function that transforms mouse coordinates to canvas pixel coordinates: /* Returns pixel coordinates according to the pixel that's under the mouse cursor**/ HTMLCanvasElement.prototype.relativeCoords = function(event) { var x,y; //This is the current screen rectangle of canvas var rect = this.getBoundingClientRect(); //Recalculate mouse offsets to relative offsets x = event.clientX - rect.left; y = event.clientY - rect.top; //Also recalculate offsets of canvas is stretched var width

问题 QUESTION: Is there a way that I could locate what the coordinates are of corner points of the google map each time I zooms in , zooms out , or shift the map? ELABORATING ON WHAT I MEAN: In my google maps api code, I giving the map a specific width and height: <style> #map { width:400px; height:300px; } </style> <script src="https://maps.googleapis.com/maps/api/js"></script> <div id="map"></div> <script> var mapOptions = { center: new google.maps.LatLng(37.7831, -122.4039), zoom: 12, mapTypeId

问题 where can I get a list of that? I need the coords of the distrits and cantons of Costa Rica, is there a place to get those? thanks in advance 回答1: geonames.org is a public database of all cities/towns with a population over 1000. The data for each city includes geo coordinates and administrative division, which I believe would be your districts, provinces or cantons. 回答2: Check out the Costa Rica link here - it may suit your needs. I found it with this search: http://www.bing.com/search?q=
