  • Simple question about MKMapView and the iPhone

    - by gravityone
    Basically I want to show the users location plus a list of selected location on a map. It can even have the standard iphone annotations. But, I have no idea of the general steps I would take to achieve this. Would I use MKMapView, or Core Location, or both? Could someone give me a simple outline of steps to take, or a link to a good tutorial or sample code. Thanks

  • Modify jkpanel to load internal content instead of external content

    - by Adam Stone
    I am using an implementation of jkpanel in a vb.net app, the script (see below) loads an external file into the drop down panel. I need to modify this script to load an internal content like a specific div or span so that I can have this nested within the master page. //Drop Down Panel script (March 29th, 08'): By JavaScript Kit: http://www.javascriptkit.com var jkpanel={ controltext: 'Panel Content', $mainpanel: null, contentdivheight: 0, openclose:function($, speed){ this.$mainpanel.stop() //stop any animation if (this.$mainpanel.attr('openstate')=='closed') this.$mainpanel.animate({top: 0}, speed).attr({openstate: 'open'}) else this.$mainpanel.animate({top: -this.contentdivheight+'px'}, speed).attr({openstate: 'closed'}) }, init:function(file, height, speed){ jQuery(document).ready(function($){ jkpanel.$mainpanel=$('<div id="dropdownpanel"><div class="contentdiv"></div><div class="control">'+jkpanel.controltext+'</div></div>').prependTo('body') var $contentdiv=jkpanel.$mainpanel.find('.contentdiv') var $controldiv=jkpanel.$mainpanel.find('.control').css({cursor: 'wait'}) $contentdiv.load(file, '', function($){ var heightattr=isNaN(parseInt(height))? 'auto' : parseInt(height)+'px' $contentdiv.css({height: heightattr}) jkpanel.contentdivheight=parseInt($contentdiv.get(0).offsetHeight) jkpanel.$mainpanel.css({top:-jkpanel.contentdivheight+'px', visibility:'visible'}).attr('openstate', 'closed') $controldiv.css({cursor:'hand', cursor:'pointer'}) }) jkpanel.$mainpanel.click(function(){jkpanel.openclose($, speed)}) }) } } //Initialize script: jkpanel.init('path_to_content_file', 'height of content DIV in px', animation_duration) jkpanel.init('panelcontent.htm', '200px', 500) Does anybody have any idea on how to modify this to do so or even have any tips or pointers to point me in the right direction to start doing so. Cheers

  • How do I add values to semi-complex JSON object?

    - by Nick Verheijen
    I'm fairly new to using JSON objects and I'm kinda stuck. I've got an JSON object that was converted from this array: Array ( [status] => success [id] => 1 [name] => Zone 1 [description] => Awesome zone deze.. [tiles] => Array ( // Column for the tile grid [0] => Array ( // Row for the tile grid [0] => Array ( [tileID] => 1 [rotation] => 0 ) [1] => Array ( [tileID] => 1 [rotation] => 0 ) // Etc.. ) [1] => Array // etc.. etc.. ) ) I use this object to render out an isometric grid for my HTML5 Canvas game. I'm building a map editor and to put more tiles on the map, i'll have to add values to this json object. This is how I would do it in PHP: mapData[column][row] = array( 'tileID' => 1, 'rotation' => 0 ); So my question is, how do I achieve this with a JSON object in javascript? Thanks in advance! Nick Update I've ran into an error: can't convert undefined to object mapDataTiles[mouseY][mouseX] = { tileID: editorSelectedTile, rotation: 0 }; This is the code i use for clicking & then saving the new tile to the JSON object. At first I though that one of my parameters was 'undefined', so i logged those to the console but they came out perfectly.. // If there is already a tile placed on these coordinates if( mapDataTiles[mouseX] && mapDataTiles[mouseX][mouseY] ) { mapDataTiles[mouseX][mouseY]['tileID'] = editorSelectedTile; } // If there is no tile placed on these coordinates else { mapDataTiles[mouseX][mouseY] = { tileID: editorSelectedTile, rotation: 0 }; } My variables have the following values: MouseX: 5 MouseY: 17 tileID: 2 Also weird fact, that for some coordinates it does actually work and save new data to the array. mapDataTiles[mouseY][mouseX] = { tileID: editorSelectedTile, rotation: 0 };

  • How to get a fully transparent backbuffer in directx 9 without vista Desktop Window Manager

    - by flawlesslyfaulted
    I currently have an activex control that initiates a media (video/audio) framework another development group in my company developed and I am providing a window handle to that code. That handle is being used by their rendering plugin in the pipeline that uses Direct3d for rendering the video using that handle. I have seperate LPDIRECT3D9EX and LPDIRECT3DDEVICE9EX pointers that I initialize in my activex control. I am trying to clear a backbuffer to transparent and then use directx drawing primatives to draw on that backbuffer producing a transparent window with my drawing primatives over the streaming video on the directx surface below. It appears that clearing a device backbuffer with full alpha transparency is ignored by directx. d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_RGBA(0, 0, 1, 0 /*full alpha*/), 1.0f, 0); I can see the object I draw but they are drawn on top of a backbuffer that has the RGB color specified without the alpha value. The project linked (http://www.codeproject.com/KB/directx/umvistad3d.aspx) to in the stackoverflow question below does what I want but requires vista's Desktop Window Manager and won't work for XP. http://stackoverflow.com/questions/148275/how-do-i-draw-transparent-directx-content-in-a-transparent-window I have tried with D3DRS_ALPHABLENDENABLE true with configured blend with no avail. I have also tried to have pixels with full alpha values not rendered using D3DRS_ALPHATESTENABLE, D3DRS_ALPHAREF, and D3DRS_ALPHAFUNC setup but this doesn't work either. I have tried using ColorFill with alpha after retrieving the backbuffer with GetBackBuffer but this doesn't work either. (again only RGB is used) Finally I have tried creating a texture, selecting a surface, colorfilling that surface with a fully transparent alpha value, then loading that surface onto the backbuffer but only the RGB values appear to be used. I have checked the capabilities using the DXCapsViewer.exe and the D3DFMT_A8R8G8B8 backbuffer format that I am using for the backbuffer is valid so it can't be that. Has anyone gotten a transparent backbuffer in directx to work in XP?

  • intersection of three sets in python?

    - by Phil Brown
    Currently I am stuck trying to find the intersection of three sets. Now these sets are really lists that I am converting into sets, and then trying to find the intersection of. Here's what I have so far: for list1 in masterlist: list1=thingList1 for list2 in masterlist: list2=thingList2 for list3 in masterlist: list3=thingList3 d3=[set(thingList1), set(thingList2), set(thingList3)] setmatches c= set.intersection(*map(set,d3)) print setmatches and I'm getting set([]) Script terminated. I know there's a much simpler and better way to do this, but I can't find one...

  • Registry remotley hacked win 7 need help tracking the perp

    - by user577229
    I was writing some .VBS code at thhe office that would allow certain file extensions to be downloaded without a warning dialog on a w7x32 system. The system I was writing this on is in a lab on a segmented subnet. All web access is via a proxy server. The only means of accessing my machine is via the internet or from within the labs MSFT AD domain. While writing and testing my code I found a message of sorts. Upon refresing the registry to verify my code changed a dword, instead the message HELLO was written and visible in regedit where the dword value wass called for. I took a screen shot and proceeded to edit my code. This same weird behavior occurred last time I was writing registry code except on another internal server. I understand that remote registry access exists for windows systems. I will block this immediately once I return to the office. What I want to know is, can I trace who made this connection? How would I do this? I suspect the cause of this is the cause of other "odd" behaviors I'm experiencing at work such as losing control of my input director master control for over an hour and unchanged code that all of a sudden fails for no logical region. These failures occur at funny times, whenver I'm about to give a demonstration of my test code. I know this sounds crazy however knowledge of the registry component makes this believable. Once the registry can be accessed, the entire system is compromised. Any help or sanity checking is appreciated.

  • ProgressDialog does not disappear after executing dismiss, hide or cancel?

    - by Martin
    Hello, I have an Overlay extension which has 2 dialogs as private attributes - one Dialog and one ProgressDialog. After clicking on the Overlay in the MapView, the Dialog object appears. When the user clicks a button in the Dialog it disappears and the ProgressDialog is shown. Simultaneously a background task is started by notifying a running Service. When the task is done, a method (buildingLoaded) in the Overlay object is called to switch the View and to dismiss the ProgressDialog. The View is being switched, the code is being run (I checked with the debugger) but the ProgressDialog is not dismissed. I also tried hide() and cancel() methods, but nothing works. Can somebody help me? Android version is 2.2 Here is the code: public class LODOverlay extends Overlay implements OnClickListener { private Dialog overlayDialog; private ProgressDialog progressDialog; .............. @Override public void onClick(View view) { ....... final Context ctx = view.getContext(); this.progressDialog = new ProgressDialog(ctx); ListView lv = new ListView(ctx); ArrayAdapter<String> adapter = new ArrayAdapter<String>(ctx, R.layout.layerlist, names); lv.setAdapter(adapter); final LODOverlay obj = this; lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String name = ((TextView) view).getText().toString(); Intent getFloorIntent = new Intent(Map.RENDERER); getFloorIntent.putExtra("type", "onGetBuildingLayer"); getFloorIntent.putExtra("id", name); view.getContext().sendBroadcast(getFloorIntent); overlayDialog.dismiss(); obj.waitingForLayer = name; progressDialog.show(ctx, "Loading...", "Wait!!!"); } }); ....... } public void buildingLoaded(String id) { if (null != this.progressDialog) { if (id.equals(this.waitingForLayer)) { this.progressDialog.hide(); this.progressDialog.dismiss(); ............ Map.flipper.showNext(); // changes the view } } } }

  • Webbrowser locks first Excel Instance

    - by figus
    VB.NET 2008 - WinForms Hi Everyone! I've been looking for an answer to my problem but I only find more questions related to my problem... The thing is that I'm using a AxWebBrowser control in VB.NET 2008 to open a excel file in a WindowsForm, it opens succesfully and everything... but the problem is this: If I had a Excel File Open before opening another Excel File in my WebBrowser Control, the window that contains the file that was already open gets locked... (I can't give focus to that Excel window... If I click on it, the focus returns to my application) I tried creating a new excel instance with CreateObject("Excel.Application") just before loading the file, but the WebBrowser locks the first Excel Instance... Is there a way to lock it to the last instance??? I use the WebBrowser1.Navigate(Url) method to load the file... where Url is a String like C:\myExcelFile.xlsm WebBrowser1.Document.Application.UserControl is also True, but it get's locked. Any Suggestion?? Thanks in Advance!!!

  • restrict script inside iframe to run only within pages of same top-level domain?

    - by Justin Grant
    I'd like to enforce a requirement that client script inside a page (which in turn is loaded inside an iframe of another page) will only run when the parent page is on the same top-level domain as the framed page (although it may be on another hostname in that domain). Is this do-able? I assume that the easy solution of looking at top.location.host won't be available due to cross-site scripting limitations, but I'm wondering if other javascript hackery could suffice. Constraints on any potential solution inculde: I need to be able to run XmlHttpRequest calls inside the child page, and I need to validate that the hostname is in the same domain before I make those calls. (this makes a document.domain solution challenging because AFAIK setting document.domain disables the ability to make XmlHttpRequest calls. I can control client-side script and HTML on both parent or child (and I can create new pages if needed), but I can't make any server-side code changes. I can't simulate the above via server-side calls or proxies, because the child page's hostname uses a forms auth system with hostname-scoped cookies that I can't get access to from the parent page since it's on a different hostname. I don't have enough control over the child-frame site to be able to put both sites behind the same reverse-proxy or load-balancer (which would enable me to put both sites on the same hostname). I don't actually need to access any UI inside the IFrame-- the iframe is invisible and I'm only using it to run javascript within the security context of a site on a different hostname from the parent page. So at this point I'm stumped. Got any ideas? I want to make sure I'm not overlooking an easy solution before giving up.

  • ASP.NET auto-generate aspx.designer.cs turn off?

    - by Joris
    Hey all, As I'm working on a asp.net/c# project, I'm confronted with the foobar.aspx.designer.cs that auto generates it's content. eg, when I'm changing the code/designer, the designer.cs automatically updates it's content. As I'm bit of a control-dude, I'd like to maintain the code myself. I'm not happy with the overkill of comments I don't need. Like: /// <summary> /// Form1 control. /// </summary> /// <remarks> /// Auto-generated field. /// To modify move field declaration from designer file to code-behind file. /// </remarks> protected global::System.Web.UI.HtmlControls.HtmlForm Form1; While I'd like to see the following: protected global::System.Web.UI.HtmlControls.HtmlForm Form1; protected global::System.Web.UI.WebControls.Button Button3; etc, etc (don't mind the naming, ofcourse I'd give it some distinguishing nameing) How to fix this? I checked google on this one, but couldn't find an answer so quickly...

  • JQuery val() does not work for textarea in Opera

    - by Anil Soman
    I am displaying a modal dialog using jQuery. This dialog has a textarea control on it. But on submitting this dialog, the value of this textarea is not recognized by jQyery for some reason. It always comes blank. This works perfectly in other browsers. I put alert to display the value but it looks blank. Can anybody help me in this regards? Controls <input type="text" id="txtGroupName"/> <textarea rows="3" cols="30" id="txtDescription"></textarea> jQuery code which used this value var postData = new Object(); postData.GroupName = $('#txtGroupName').val(); postData.Description = $('#txtDescription').val(); $('#txtDescription').val() comes blank but $('#txtGroupName').val() is read correctly as it is a input field. One more finding about this issue: When I put alert in my update function after populating the control value on page load, this alert displays the existing value properly. But it displays only existing value. It does not display the edited value after submitting the modal box.

  • Numeric operations over SHA-1 generated keys in C#

    - by webdreamer
    I'm trying to implement a Chord distributed hash table. I want to use SHA-1 as the hash function to generate node ids and map values to the DHT. However, I'll need to use numerical operations on the SHA-1 generated key, such as a modulo, for example. I wonder in which type of variable should I put the array of bytes I get, and how can I convert from one to another.

  • File Handler returning garbled files.

    - by forcripesake
    For the past 3 months my site has been using a PHP file handler in combination with htaccess. Users accessing the uploads folder of the site would be redirected to the handler as such: RewriteRule ^(.+)\.*$ downloader.php?f=%{REQUEST_FILENAME} [L] The purpose of the file handler is pseudo coded below, followed by actual code. //Check if file exists and user is downloading from uploads directory; True. //Check against a file type white list and set the mime type(); $ctype = mime type; header("Pragma: public"); // required header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private",false); // required for certain browsers header("Content-Type: $ctype"); header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" ); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($filename)); readfile("$filename"); As of yesterday, the handler started returning garbled files, unreadable images, and had to be bypassed. I'm wondering what settings could have gone awry to cause this.

  • How do you sort a C# dictionary by value?

    - by kurious
    I often have a Dictionary of keys & values and need to sort it by value. For example, I have a hash of words and their frequencies, and want to order them by frequency. There's SortedList which is good for a single value (frequency), but I want to map it back to the word. SortedDictionary orders by key, not value. Some resort to a custom class, but what's the cleanest way?

  • Looking for pros/cons of using GWT or JSF

    - by cliff.meyers
    I'm a long time Java developer who has been building UI with Adobe Flex for the past few years. I'm looking to broaden my repertoire with a RIA technology that runs in a plain-old browser, no plug-ins required. I've read a lot about GWT but don't know much about JSF, especially given the varying implementations. Below are some criteria that are important to me as a developer. I'm hoping that the community might be able to tell me about the strengths and weaknesses of GWT and JSF in each: Layout: is it declarative, programmatic or a mix of both? Control library: how rich is the available control library? How easy is it to extend or write custom controls that "play nice" with the built-ins? Javascript: how much of it do I need to write in order to be successful with the framework? Cross-browser: assuming I'm not writing a lot of my own HTML and JS, do the frameworks function equally well in all modern browsers? Tooling: is a rapid edit/refresh cycle available? How easy is it to debug the client and server code? Bookmarking / Browser Navigation: this is a common problem in Flex; does the framework play nicely with these? I would love to hear any other important pros / cons I might not have covered. Thanks!
