    - by MikeStardust

  • What do you call the highlight as you hover over an OPTION in a SELECT, and how can I "un"highlight

    - by devils-avacado
    I'm working on dropdowns in IE6 (SELECT with OPTIONs as children). I'm experiencing the problem where, in IE6, dropdown menus are truncated to the width of the SELECT element. I used this jquery to fix it: var css_expanded = { 'width' : 'auto', 'position' : 'absolute', 'left' : '564px', 'top' : '393px' } var css_off = { 'width' : '190px', 'position' : 'relative', 'left' : '0', 'top' : '0' } if($.browser.msie) { $('#dropdown') .bind('mouseover', function() { $(this).css(css_expanded); }) .bind('click', function() { $(this).toggleClass('clicked'); }) .bind('mouseout', function() { if (!$(this).hasClass('clicked')) { $(this).css(css_off); } }) .bind('change blur focusout', function() { $(this).removeClass('clicked') .css(css_off) }); }; It works fine in IE7+8, but in IE6, if the user clicks on a SELECT and does not click any OPTION but instead clicks somewhere else on the page, outside the SELECT (blur), the SELECT still has a "highlight", the same as if they were hovering over an OPTION with my mouse (in my case, a blue color), and the width is not restored until the user clicks outside the SELECT a second time. In other browsers, blur causes every OPTION to not be highlighted. Using JS, how can I de-highlight an option after the dropdown has lost focus.

  • jQuery Suspected Naming Convention Problem

    - by donfigga
    Hi all, I'm having a problem with this jQuery function, the portion of the function that renames the id, class and name of the dropdown only works for the first dropdown, subsequent ones do not work, any ideas? I suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

  • Refreshing a MKMapView when the user location is updated or using default values

    - by koichirose
    I'm trying to refresh my map view and load new data from the server when the device acquires the user location. Here's what I'm doing: - (void)viewDidLoad { CGRect bounds = self.view.bounds; mapView = [[MKMapView alloc] initWithFrame:bounds]; mapView.showsUserLocation=YES; mapView.delegate=self; [self.view insertSubview:mapView atIndex:0]; [self refreshMap]; } - (void)mapView:(MKMapView *)theMapView didUpdateUserLocation:(MKUserLocation *)userLocation { //this is to avoid frequent updates, I just need one position and don't need to continuously track the user's location if (userLocation.location.horizontalAccuracy > self.myUserLocation.location.horizontalAccuracy) { self.myUserLocation = userLocation; CLLocationCoordinate2D centerCoord = { userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude }; [theMapView setCenterCoordinate:centerCoord zoomLevel:10 animated:YES]; [self refreshMap]; } } - (void)refreshMap { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; [self.mapView removeAnnotations:self.mapView.annotations]; //default position NSString *lat = @"45.464161"; NSString *lon = @"9.190336"; if (self.myUserLocation != nil) { lat = [[NSNumber numberWithDouble:myUserLocation.coordinate.latitude] stringValue]; lon = [[NSNumber numberWithDouble:myUserLocation.coordinate.longitude] stringValue]; } NSString *url = [[NSString alloc] initWithFormat:@"http://myserver/geo_search.json?lat=%@&lon=%@", lat, lon]; NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; [url release]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; } I also have a - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data, to create and add the annotations. Here's what happens: sometimes I get the location after a while, so I already loaded data close to the default location. Then I get the location and it should remove the old annotations and add the new ones, instead I keep seeing the old annotations and the new ones are added anyway (let's say I receive 10 annotations each time, so it means that I have 20 on my map when I should have 10). What am I doing wrong?

  • StreamReader returning another char

    - by Fernando
    I'm trying to read the content of a file with a StreamReader, that receives a FileStream. The file has some spaces inside (char 32) and the StreamReader is reading them as 0 (char 48). The screenshot shows the FileStream buffer and the StreamReader buffer. Both have the value 32, but when I call Read(), it returns 48. Am I missing something here? By the way, the code is running under .NET Compact Framework. The code that reads the data: public void Read() { using (StreamReader reader = new StreamReader(InputStream, Encoding.ASCII)) { foreach (var property in DataObject.EnumerateProperties()) { OffsetInfo offset = property.GetTextOffset(); reader.BaseStream.Position = offset.Start - 1; StringBuilder builder = new StringBuilder(offset.Size); int count = 0; while (reader.Peek() >= 0 && count < offset.Size) { char c = (char)reader.Read(); if ((int)c != 32 && c != '\r' && c != '\n') { builder.Append(c); count++; } else { reader.BaseStream.Position++; } } property.SetValue(DataObject, Convert.ChangeType(builder.ToString(), property.PropertyType, CultureInfo.CurrentCulture), null ); } } }

  • jQuery Manual Resizable DIV

    - by JC
    Hi, I'm trying to create a resizable div without using jQuery's interface library. var myY = 0; var mouseDown = false; var originalHeight = 0; function resize(e){ if(mouseDown == true){ $("#cooldiv").height(originalHeight+e.pageY-myY); } } $(document).ready(function(){ $().mouseup(function(e){ myY = 0; mouseDown = false; originalHeight = 0; $().unbind("mousemove", resize); }); $("#resizeBar").mousedown(function(e){ myY = e.pageY; originalHeight = $("#cooldiv").height(); mouseDown = true; $().bind("mousemove", resize); }); }); ... <div id="cooldiv" style="width: 500px; height: 300px; background-color: #cccccc; position: relative;"> <div id="resizeBar" style="height: 10px; width: 500px; background-color: #aaaaaa; position: absolute; bottom: 0;"></div> </div> The first resize works fine(i.e. mousedown, mousemove then mouseup), but on subsequent (mousedown+mousemove)s, the browser attempts to drag the whole resizeBar div instead of properly resizing its parent container. On mouseup, the div then starts resizing "cooldiv" on mousemove without any mousedown required, until a further click of the mouse. These problems don't show up in Internet Explorer.

  • Improving File Read Performance (single file, C++, Windows)

    - by david
    I have large (hundreds of MB or more) files that I need to read blocks from using C++ on Windows. Currently the relevant functions are: errorType LargeFile::read( void* data_out, __int64 start_position, __int64 size_bytes ) const { if( !m_open ) { // return error } else { seekPosition( start_position ); DWORD bytes_read; BOOL result = ReadFile( m_file, data_out, DWORD( size_bytes ), &bytes_read, NULL ); if( size_bytes != bytes_read || result != TRUE ) { // return error } } // return no error } void LargeFile::seekPosition( __int64 position ) const { LARGE_INTEGER target; target.QuadPart = LONGLONG( position ); SetFilePointerEx( m_file, target, NULL, FILE_BEGIN ); } The performance of the above does not seem to be very good. Reads are on 4K blocks of the file. Some reads are coherent, most are not. A couple questions: Is there a good way to profile the reads? What things might improve the performance? For example, would sector-aligning the data be useful? I'm relatively new to file i/o optimization, so suggestions or pointers to articles/tutorials would be helpful.

  • Loading city/state from SQL Server to Google Maps?

    - by knawlejj
    I'm trying to make a small application that takes a city & state and geocodes that address to a lat/long location. Right now I am utilizing Google Map's API, ColdFusion, and SQL Server. Basically the city and state fields are in a database table and I want to take those locations and get marker put on a Google Map showing where they are. This is my code to do the geocoding, and viewing the source of the page shows that it is correctly looping through my query and placing a location ("Omaha, NE") in the address field, but no marker, or map for that matter, is showing up on the page: function codeAddress() { <cfloop query="GetLocations"> var address = document.getElementById(<cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput>).value; if (geocoder) { geocoder.geocode( {<cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput>: address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location, title: <cfoutput>#Trim(hometown)#,#Trim(state)#</cfoutput> }); } else { alert("Geocode was not successful for the following reason: " + status); } }); } </cfloop> } And here is the code to initialize the map: var geocoder; var map; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(42.4167,-90.4290); var myOptions = { zoom: 5, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } var marker = new google.maps.Marker({ position: latlng, map: map, title: "Test" }); map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } I do have a map working that uses lat/long that was hard coded into the database table, but I want to be able to just use the city/state and convert that to a lat/long. Any suggestions or direction? Storing the lat/long in the database is also possible, but I don't know how to do that within SQL.

  • IE6: Height "1em minus 1px"

    - by chris_l
    I need a div with a height of exactly 1em minus 1px. This can be achieved in most browsers like this: <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <style type="text/css"> .helper { /* background-color: black; */ position: absolute; top: 5em; left: 5em; width: 2em; height: 1em; } .target { background-color: #89f; position: absolute; top: 0; bottom: 1px; width: 100%; } </style> </head> <body> <div class="helper"> <div class="target"></div> </div> </body> </html> The "target" div has the desired height. The problem is, that this doesn't work in IE6, because it ignores the bottom attribute, when top is set (a well known problem). Is there a workaround for IE6 (maybe with multiple nested divs, with borders/paddings/margins/whatever), or will JavaScript be the only solution? Please note, that I can't use Quirks Mode.

  • Effective communication in a component-based system

    - by Tesserex
    Yes, this is another question about my game engine, which is coming along very nicely, with much thanks to you guys. So, if you watched the video (or didn't), the objects in the game are composed of various components for things like position, sprites, movement, collision, sounds, health, etc. I have several message types defined for "tell" type communication between entities and components, but this only goes so far. There are plenty of times when I just need to ask for something, for example an entity's position. There are dozens of lines in my code that look like this: SomeComponent comp = (SomeComponent)entity.GetComponent(typeof(SomeComponent)); if (comp != null) comp.GetSomething(); I know this is very ugly, and I know that casting smells of improper OO design. But as complex as things are, there doesn't seem to be a better way. I could of course "hard-code" my component types and just have SomeComponent comp = entity.GetSomeComponent(); but that seems like a cop-out, and a bad one. I literally JUST REALIZED, while writing this, after having my code this way for months with no solution, that a generic will help me. SomeComponent comp = entity.GetComponent<SomeComponent>(); Amazing how that works. Anyway, this is still only a semantic improvement. My questions remain. Is this actually that bad? What's a better alternative?

  • Getting moved out of a development job

    - by Jay
    I'm a year out of college and I started my first dev job at a small (<15 people) company several months ago. It was an internship position that recently turned full time. The position started out as development but for full time I got offered a grab bag of positions: qa, docs, call support and some dev work. It's clear that my employers feel I am lacking dev skills, which is true. I did not major in CS in college and did not have much dev experience. However, I'm convinced that I can be a good developer and I will be a good developer once given the chance to write lots of code. My question is simple: what should I do? As I see it, there are two options. Work hard in the non-dev duties so that my employers may eventually give me significant dev responsibilities. Look for a new job where I will be a developer first and an all purpose guy second (if at all). Thanks guys.

  • SetWindowPos has not effect on tooltip

    - by YoungPony
    Hello, I am trying to give my ComboBox an in place tooltip for long strings. However when I call SetWindowPos on the tooltip, the position is never changed. Called when TTN_SHOW is received: ::SetWindowPos(textTooltip, NULL, TipRect.left, TipRect.top, 0, 0, SWP_NOSIZE | SWP_NOACTIVATE | SWP_NOZORDER); If I remove the SWP_NOSIZE flag and pop in some values into the width/height, then the combo box changes size to these values but the position remains the same. SetWindowPos always returns TRUE. The tip is initialised like so: textTooltip = CreateWindowEx(WS_EX_TRANSPARENT, TOOLTIPS_CLASS, NULL, TTS_NOPREFIX, 0, 0, 0, 0, this->GetSafeHwnd(), NULL, NULL, NULL); if(!textTooltip) return; ZeroMemory(&ToolInfo, sizeof(TOOLINFO)); ToolInfo.cbSize = sizeof(TOOLINFO); ToolInfo.uFlags = TTF_TRANSPARENT | TTF_SUBCLASS; ToolInfo.hwnd = this->GetSafeHwnd(); ToolInfo.lpszText = "place holder"; //set in OnSelectChangeOk ToolInfo.uId = 0; ToolInfo.rect = TipRect; //rect is re-set in OnSelectChangeOk ::SendMessage(textTooltip, TTM_ADDTOOL, 0, (LPARAM)&ToolInfo); Am I missing something?

  • Why pseudo-elements :before and :after appear in front of my DIV element and not behind?

    - by Dim13i
    I have a DIV element with this given class: .slideshow { background: white; width: 700px; height: 300px; padding:10px; margin: 0 auto; position: relative; box-shadow: 0px 0px 5px grey, 0px 10px 20px rgba(0,0,0,.1) inset; } I define those two pseudo-elements (:before and :after): .slideshow:before, .slideshow:after { content: " "; background: green; width: 50%; height: 50%; position: absolute; z-index: -10; } My problem is that those two pseudo-elements appear in front of my DIV and not behind. Is there any specific reason for this behaviour? Here is an example: EXAMPLE The Javascript part is a bit messy but i'm still working on it. Also I've noticed that if I delete all the JS part I don't have anymore this problem, but I don't think there is anything in the code that should modify the slideshow DIV SOLVED: The problem is in the javascript part where I have: $('.slideshow').css('-webkit-transform', 'rotate(0deg)'); Removing this line solved the problem. I guess that pseudo-elements :before and :after are not compatible with the property transform.

  • Parsing: How to make error recovery in grammars like " a* b*"?

    - by Lavir the Whiolet
    Let we have a grammar like this: Program ::= a* b* where "*" is considered to be greedy. I usually implement "*" operator naively: Try to apply the expression under "*" to input one more time. If it has been applied successfully then we are still under current "*"-expression; try to apply the expression under "*" one more time. Otherwise we have reached next grammar expression; put characters parsed by expression under "*" back into input and proceed with next expression. But if there are errors in input in any of "a*" or "b*" part such a parser will "think" that in position of error both "a*" and "b*" have finished ("let's try "a"... Fail! OK, it looks like we have to proceed to "b*". Let's try "b"... Fail! OK, it looks like the string should have been finished...). For example, for string "daaaabbbbbbc" it will "say": "The string must end at position 1, delete superflous characters: daaaabbbbbbc". In short, greedy "*" operator becomes lazy if there are errors in input. How to make "*" operator to recover from errors nicely?

  • jquery suspected naving convention problem

    - by donfigga
    Hi all im having provlem with this jquery function, the protion of the function that renames the id, class and name of the dropdown only works for the first dropdown, susequest ones do not work , any ideas, i suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

  • GWT + Seam, cannot fetch scoped beans from gwt servlet in seam resource servlet.

    - by David Göransson
    Hello all I am trying to get session and conversation scoped beans to a gwt servlet in the seam resource servlet. I have a conversation scoped bean: @Name ("viewFormCopyAction") @Scope (ScopeType.CONVERSATION) public class ViewFormCopyAction {} and a session scoped bean: @Name ("authenticator") @Scope (ScopeType.SESSION) public class AuthenticatorAction {} There is a RemoteService interface: @RemoteServiceRelativePath ("strokesService") public interface StrokesService extends RemoteService { public Position getPosition (int conversationId); } with corresponding async interface: public interface StrokesServiceAsync extends RemoteService { public void getPosition (int conversationId, AsyncCallback callback); } and implementation: @Name ("com.web.actions.forms.gwt.client.StrokesService") @Scope (ScopeType.EVENT) public class StrokesServiceImpl implements StrokesService { @In Manager manager; @Override @WebRemote public Position getPosition (int conversationId) { manager.switchConversation( "" + conversationId ); ViewFormCopyAction vfca = (ViewFormCopyAction) Component.getInstance( "viewFormCopyAction" ); AuthenticatorAction aa = (AuthenticatorAction) Component.getInstance( "authenticator" ); return null; } } The gwt page is within an IFrame in a regular seam page and the conversationId is propagted with the src attribute of the IFrame. Both bean objects end up with only null values. Can anyone see anything wrong with the code? I know that I could use strings instead of the int, but never mind that at this point.

  • ListView setOnItemClickListener in ListFragment not working

    - by Siddarth Kaki
    I am developing an app that uses ActionBar tabs to display a list of options through ListFragment. The list (and ListFragment) display without a problem, but the ListView's setOnItemClickListener doesn't seems to work, as nothing happens when an item in the list is clicked. Here's the code for the ListFragment class: package XXX.XXX; public class AboutFrag extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.aboutfrag, container, false); ListView lv = (ListView) view.findViewById(android.R.id.list); String[] items = new String[] {"About 1", "About 2", "About 3"}; lv.setAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_item, items)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { switch (position) { case 0: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com")); startActivityForResult(browserIntent, 0); break; case 1: Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org")); startActivityForResult(browserIntent2, 0); break; case 2: Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com"); startActivityForResult(browserIntent3, 0); break; } } }); return view; } } I'm assuming it does not work because the class returns the view object, so the FragmentActivity can't run the listener code, so does anyone know how to make this work? By the way, I am using ActionBarSherlock. Thanks in advance!!!

  • Can we solve the table row background image problem, in chrome, in multi celled tables??

    - by Ya'el
    It is frequently asked – but I haven’t seen a good answer yet (and I looked). If you set a background image in CSS to a table row- the image will repeat itself in every cell. If you set the position: relative (for the row) and set the background-image: none (for the cells) it solves the problem on IE but not on chrome! I can't use background positioning since there are many calls and their size varies. (And the picture is not symmetrical- It's a fade out from one side. Anybody?? Example for the css code : tr { height: 30px; position:relative;} tr.green {background: url('green_30.png') no-repeat left top;} tr.orange {background: url('oranger_30.png') no-repeat left top;} tr.red {background: url('red_30.png') no-repeat left top;} td {background-image:none;} The HTML is basic - A multi cell table. The goal is to have different colors fade into every row, but it could be any non-pattern image.

  • Why does my JQuery Image swap not work in firefox or chrome, but fine in IE?

    - by Cognize
    Hi, Relatively new to JQuery. I've got some code that does a banner swap with a fade in fade out transition. The images swap as expected in IE8, chrome, and firefox. However, the actual fade, the smooth transition between images only works in IE. Can anyone point me in the right direction for a fix? Javascript: function swapImages() { var $active = $('#transitionImagePlaceHolder .active'); var $next = ($('#transitionImagePlaceHolder .active').next().length > 0) ? $('#transitionImagePlaceHolder .active').next() : $('#transitionImagePlaceHolder img:first'); $active.fadeOut( 'slow', function () { $next.fadeIn('slow').addClass('active'); $active.removeClass('active'); }); } $(document).ready(function () { setInterval('swapImages()', 5000); }); CSS: #transitionImagePlaceHolder { } #transitionImagePlaceHolder { position:relative; left: 26px; } #transitionImagePlaceHolder img { display:none; position:absolute; top:4; left:10; } HTML: <div id="transitionImagePlaceHolder"> <img class="active" src="Images/TransitionImages/Trans_Img_1.jpg" /> <img src="Images/TransitionImages/Trans_Img_2.jpg" /> <img src="Images/TransitionImages/Trans_Img_3.jpg" /> </div>

  • How To Read A Remote Text File

    - by XcodeDev
    Hi, I would like to read a remote text file called posts.txt on my website. An example of the insides of the posts.txt file would be this: <div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by iSDK</i></font><br><img src="Bar.png" /></div><div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by martin</i></font><br><img src="Bar.png" /></div> What I wanted to know is how can I get the score, and scored by text from the .txt file? The score is (in this case) the: <b>2</b>, and the scored by text in this case would be: "scored by iSDK". Any code telling me how to do this is twice as helpful! Thanks in advanced XcodeDev

  • Java side scrolling game on android

    - by hanesjw
    I'm trying to make an easy side scrolling game just to learn the ropes of game programming on android. I came up with a solution of how to make it but I don't really think it is the most elegant solution. I wanted to get some different ideas on how to implement my game, as I really have no other solution right now. Here is a quick explanation of how it works.. I basically have blocks or objects fall from the top of the screen. The blocks are defined from a pre-defined string I create using a custom 'map-editor'. I create all the blocks at compile time, position them on or off the screen and simply increment their coordinates with each iteration of the gameloop. It is actually done a little bit better then that, but that gives a short easy explanation on the basic idea. I heard from a few people that instead of incrementing each block position, have the blocks stay there and simply change the viewable area. That makes sense, but I have no idea how to do it. Can anyone share some ideas or links on how I can implement something like this? I know my current solution isn't the greatest. Thanks!

  • Drupal 6: creating different profiles to list at custom page adding page and selecting as many as i

    - by artmania
    Hi friends, I'm a newbie drupal... I'm working on my first Drupal project. I need to make an events page for some conferences. I create event content type, and creating fields like date-place-title-etc with CCK. There are also speakers, can be up to 20. each speaker has photo-namesurname-position. same speaker can be added to more than 1 event. So it is silly to create 60 fields (photo-name-position) for 20 speakers at event adding page. and expecting admin to fill all for an event adding action. there must be a way to create speakers additionally, and listing them at event adding page with checkboxes. and admin just select the speakers from the list, can be 1 or 20 speaker. how can create such thing? in what type should I create these speakers, so i can list them in event adding page for admin to select as many as he wants. Appreciate helps so much!! thanks a lot!

  • Cocos2d on iPhone: Using Sprites Defined in Separate Class Files.

    - by srikanth rongali
    I'm trying to draw two sprites on the same screen. I have defined the two sprite objects in two separate class files. If I comment out two lines (see "item 1" comment below) then I get a display as [a backgroundimage[background2.jpg] with a sprite[grossini.png] on the left side. If I uncomment the two lines I do not get the background image and sprite of (gameScreen.m). I get only the sprite [grossinis_sister1.png] defined in (enemy.m). But what I need is a [backgroundimage[background2.jpg]], sprite[grossini.png] and sprite [grossinis_sister1.png] in one screen. This is implementation file of my first class: #import "gameScreen.h" #import "enemy.h" @implementation gameScreen -(id)init { if((self = [super init])) { CCSprite *backGroundImage = [CCSprite spriteWithFile:@"background2.jpg"]; backGroundImage.anchorPoint = ccp(0,0); CCParallaxNode *voidNode = [CCParallaxNode node]; [voidNode addChild:backGroundImage z:-1 parallaxRatio:ccp(0.0f,0.0f) positionOffset:CGPointZero]; [self addChild:voidNode]; CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCSprite *player = [CCSprite spriteWithFile:@"grossini.png"]; player.position = ccp(player.contentSize.width/2, windowSize.height/2); [self addChild:player z:0]; //eSprite = [[enemy alloc]init]; //<-- see item 1 //[self addChild:eSprite]; } return self; } This is my implementation file of my second class: #import "enemy.h" #import "gameScreen.h" @implementation enemy -(id)init { if ((self = [super init])) { CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCSprite *enemySprite = [CCSprite spriteWithFile:@"grossinis_sister1.png" ]; enemySprite.position = ccp(windowSize.width/2, windowSize.height/2); [self addChild:enemySprite]; } return self; } @end

  • Point covering problem

    - by Sean
    I recently had this problem on a test: given a set of points m (all on the x-axis) and a set n of lines with endpoints [l, r] (again on the x-axis), find the minimum subset of n such that all points are covered by a line. Prove that your solution always finds the minimum subset. The algorithm I wrote for it was something to the effect of: (say lines are stored as arrays with the left endpoint in position 0 and the right in position 1) algorithm coverPoints(set[] m, set[][] n): chosenLines = [] while m is not empty: minX = min(m) bestLine = n[0] for i=1 to length of n: if n[i][0] <= m and n[i][1] > bestLine[1] then bestLine = n[i] add bestLine to chosenLines for i=0 to length of m: if m <= bestLine[1] then delete m[i] from m return chosenLines I'm just not sure if this always finds the minimum solution. It's a simple greedy algorithm so my gut tells me it won't, but one of my friends who is much better than me at this says that for this problem a greedy algorithm like this always finds the minimal solution. For proving mine always finds the minimal solution I did a very hand wavy proof by contradiction where I made an assumption that probably isn't true at all. I forget exactly what I did. If this isn't a minimal solution, is there a way to do it in less than something like O(n!) time? Thanks
