  • Fixed div background

    - by Fahad
    I want to create a layout where I want to display an image to the left and content on the right. The image should stay constant when the content scrolls. The css I'm using: <style type="text/css"> html, body { margin:0; padding:0; } #page-container { margin:auto; width:900px; background-color:Black; background-image:url('images/desired_layout.png'); background-attachment: fixed; background-repeat:no-repeat; } #main-image { float:left; width:250px; height:687px; background-image:url('images/desired_layout.png'); background-attachment:fixed; background-repeat:no-repeat; } #content { margin-left:250px; background-color:Olive; height:800px; width:650px; } </style> The HTML: <div id="page-container"> <div id="main-image"></div> <div id="content"></div> </div> Alot of time on this site and I have understood that background-attachment:fixed positions the image in the entire viewport and not the element it is applied to. My question is how do I go about creating that kind of layout? I do not want to give that image as a background image, as if the window is resized, it might get hidden. I want scrollbars to appear if the window size is less than 900px( my page width) so that the image can be viewed at all times. That happens with this code, however I would like the image to start at my element instead. How do I go about doing this?? Thanks in Advance :)

  • UITableViewCells of different heights place their accessoryViews at different X positions

    - by Jasarien
    Hey Guys, My app has some table cells that vary in height. The cells can also have a UIButton set to be a detail disclosure button (round, blue with arrow) as their accessory view. Depending on the height of the cell, the accessory view is positioned differently. At first I thought it was my layout code for my cell that was causing the problem, so I set up a quick independent test that uses vanilla UITableCells to remove the possibility that it could be my fault. I set up a view in interface builder, and just added a view table cells to the view, set their heights to different values and then added a detail disclosure button to each. Nothing more, nothing less. This is what I see: I added the size guides (thanks to Xscope) so you can see the difference in the accessory view x positions. The heights are: top 37px mid 68px bottom 44px (default, untouched height) If I increase the height any heigher than 68px the accessory view doesn't move any further to the left. Is this a bug? Is there any way I can prevent this from happening?

  • Compile and optimize for different target architectures

    - by Peter Smit
    Summary: I want to take advantage of compiler optimizations and processor instruction sets, but still have a portable application (running on different processors). Normally I could indeed compile 5 times and let the user choose the right one to run. My question is: how can I can automate this, so that the processor is detected at runtime and the right executable is executed without the user having to chose it? I have an application with a lot of low level math calculations. These calculations will typically run for a long time. I would like to take advantage of as much optimization as possible, preferably also of (not always supported) instruction sets. On the other hand I would like my application to be portable and easy to use (so I would not like to compile 5 different versions and let the user choose). Is there a possibility to compile 5 different versions of my code and run dynamically the most optimized version that's possible at execution time? With 5 different versions I mean with different instruction sets and different optimizations for processors. I don't care about the size of the application. At this moment I'm using gcc on Linux (my code is in C++), but I'm also interested in this for the Intel compiler and for the MinGW compiler for compilation to Windows. The executable doesn't have to be able to run on different OS'es, but ideally there would be something possible with automatically selecting 32 bit and 64 bit as well. Edit: Please give clear pointers how to do it, preferably with small code examples or links to explanations. From my point of view I need a super generic solution, which is applicable on any random C++ project I have later. Edit I assigned the bounty to ShuggyCoUk, he had a great number of pointers to look out for. I would have liked to split it between multiple answers but that is not possible. I'm not having this implemented yet, so the question is still 'open'! Please, still add and/or improve answers, even though there is no bounty to be given anymore. Thanks everybody!

  • Disable chaching in JPA (eclipselink)

    - by James
    Hi, I want to use JPA (eclipselink) to get data from my database. The database is changed by a number of other sources and I therefore want to go back to the database for every find I execute. I have read a number of posts on disabling the cache but this does not seem to be working. Any ideas? I am trying to execute the following code: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one==two); one==two is true while I want it to be false. I have tried adding each/all the following to my persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.cache.size.default" value="0"/> <property name="eclipselink.cache.type.default" value="None"/> I have also tried adding the @Cache annotation to the Entity itself: @Cache( type=CacheType.NONE, // Cache nothing expiry=0, alwaysRefresh=true ) Am I misunderstanding something? Thank you, James

  • HTTP crawler in Erlang

    - by ctp
    I'm coding on a simple HTTP crawler but I have an issue running the code at the bottom. I'm requesting 50 URLs and get the content of 20+ back. I've generated few files with 150kB size each to test the crawler. So I think the 20+ responses are limited by the bandwidth? BUT: how to tell the Erlang snippet not to quit until the last file is not fetched? The test data server is online, so plz try the code out and any hints are welcome :) -module(crawler). -define(BASE_URL, "http://46.4.117.69/"). -export([start/0, send_reqs/0, do_send_req/1]). start() -> ibrowse:start(), proc_lib:spawn(?MODULE, send_reqs, []). to_url(Id) -> ?BASE_URL ++ integer_to_list(Id). fetch_ids() -> lists:seq(1, 50). send_reqs() -> spawn_workers(fetch_ids()). spawn_workers(Ids) -> lists:foreach(fun do_spawn/1, Ids). do_spawn(Id) -> proc_lib:spawn_link(?MODULE, do_send_req, [Id]). do_send_req(Id) -> io:format("Requesting ID ~p ... ~n", [Id]), Result = (catch ibrowse:send_req(to_url(Id), [], get, [], [], 10000)), case Result of {ok, Status, _H, B} -> io:format("OK -- ID: ~2..0w -- Status: ~p -- Content length: ~p~n", [Id, Status, length(B)]); Err -> io:format("ERROR -- ID: ~p -- Error: ~p~n", [Id, Err]) end.

  • How to change font color inside nav element?

    - by user2924752
    I have a element and I want to change the color of the links within it, but all other links on my page are styled using the following CSS: a:link { color:#22b14c; text-decoration:none; } and here is the nav: <nav id="Nav"> <a href="index.html">Home</a> | <a href="Gallery.html">Library</a> | <a href="Contact.html">Contact</a> | <a href="About.html">About</a> </nav> and the nav css: #Nav { margin-top: 20px; background-color: #000000; color: #f2f2f2; font-size: 40px; font-family: "Calibri"; text-align: center; } I tried a span inside the nav element but that didn't work. How can I change the color for these links only inside the element?

  • how to continuously send data without blocking?

    - by Donal Rafferty
    I am trying to send rtp audio data from my Android application. I currently can send 1 RTP packet with the code below and I also have another class that extends Thread that listens to and receives RTP packets. My question is how do I continuously send my updated buffer through the packet payload without blocking the receiving thread? public void run() { isRecording = true; android.os.Process.setThreadPriority (android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); int buffersize = AudioRecord.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); Log.d("BUFFERSIZE","Buffer size = " + buffersize); arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize); short[] readBuffer = new short[80]; byte[] buffer = new byte[160]; arec.startRecording(); while(arec.getRecordingState() == AudioRecord.RECORDSTATE_RECORDING){ int frames = arec.read(readBuffer, 0, 80); @SuppressWarnings("unused") int lenghtInBytes = codec.encode(readBuffer, 0, buffer, frames); RtpPacket rtpPacket = new RtpPacket(); rtpPacket.setV(2); rtpPacket.setX(0); rtpPacket.setM(0); rtpPacket.setPT(0); rtpPacket.setSSRC(123342345); rtpPacket.setPayload(buffer, 160); try { rtpSession2.sendRtpPacket(rtpPacket); } catch (UnknownHostException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (RtpException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } So when I send on one device and receive on another I get decent audio, but when I send and receive on both I get broken sound like its taking turns to send and receive audio. I have a feeling it could be to do with the while loop? it could be looping around in there and not letting anything else run?

  • Customize a WCF RIA Services Endpoint

    - by Andrew Garrison
    Is it possible to customize the parameters of a WCF RIA Services endpoint? Specifically, I would like to create a custom binding for the endpoint and increase the maxReceivedMessageSize to allow sending the contents of a file that is a few megabytes in size. I've tried meddling in the web.config, but I'm getting the following error: [InvalidOperationException]: The contract name MyNamespace.MyService could not be found in the list of contracts implemented by the service MyNamespace.MyService web.config <system.serviceModel> <bindings> <customBinding> <binding name="CustomBinaryHttpBinding"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> </customBinding> </bindings> <services> <service name="MyNamespace.MyService"> <endpoint address="" binding="wsHttpBinding" contract="MyNamespace.MyService" /> <endpoint address="/binary" binding="customBinding" bindingConfiguration="CustomBinaryHttpBinding" contract="MyNamespace.MyService" /> </service> </services> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>

  • Does NHibernate LINQ support ToLower() in Where() clauses?

    - by Daniel T.
    I have an entity and its mapping: public class Test { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } } public class TestMap : EntityMap<Test> { public TestMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Description); } } I'm trying to run a query on it (to grab it out of the database): var keyword = "test" // this is coming in from the user keyword = keyword.ToLower(); // convert it to all lower-case var results = session.Linq<Test> .Where(x => x.Name.ToLower().Contains(keyword)); results.Count(); // execute the query However, whenever I run this query, I get the following exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Am I right when I say that, currently, Linq to NHibernate does not support ToLower()? And if so, is there an alternative that allows me to search for a string in the middle of another string that Linq to NHibernate is compatible with? For example, if the user searches for kap, I need it to match Kapiolani, Makapuu, and Lapkap.

  • How Do I Make A Small jQuery Confirm Replacement?

    - by Volomike
    I have a table row with a Delete link on it for deleting that row. I want to create a jQuery feature that pops up above that Delete link an "Are you sure?" yes/no confirm dialog, but in a very small size. How do I achieve this in the least lines of code in jQuery? I mean, I need to determine the x,y of the Delete link that was detected from a click, and then move (and fadeIn()) a DIV into that location. If they click anywhere on that page except Yes on the yes/no, the thing does a fadeOut(). If they click Yes, then it deletes the row with a fadeOut() effect. Note on this I don't need a modal screen dimmer, but the confirm needs to work modally. (Items above that are bolded are something I don't exactly know how to do. Items bolded and italicized are important to what I need to do.) I would think a widget like this would be critical to any Web 2.0 design, much like the Pines Notify feature seems essential.

    I have a script that read a mp3 file and encrypt it, I want to be able to decrypt this file and convert it to base64 so it can play in html5. Key 1 will be stored on the page and static, key2 will be unique for each file, for testing I used: $key1 = md5(time()); $key2 = md5($key1.time()); Here is my encode php code : //Get file content $file = file_get_contents('test.mp3'); //Encrypt file $Encrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key1, $file, MCRYPT_MODE_CBC, $key2); $Encrypt = trim(base64_encode($Encrypt)); //Create new file $fileE = "test.mp3e"; $fileE = fopen($file64, 'w') or die("can't open file"); //Put crypted content fwrite($fileE, $Encrypt); //Close file fclose($fileE); Here is the code that doesnt work (decoded file is same size, but no mimetype): //Get file content $fileE = file_get_contents('test.mp3e'); //Decode $fileDecoded = base64_decode($fileE); //Decrypt file $Decrypt = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key1, $fileDecoded, MCRYPT_MODE_CBC, $key2); $Decrypt = trim($Decrypt); //Create new file $file = "test.mp3"; $file = fopen($file, 'w') or die("can't open file"); //Put crypted content fwrite($file, $Decrypt); //Close file fclose($file);

  • Opengl Iphone SDK: How to tell if you're touching an object on screen?

    - by TheGambler
    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen. I don't know if I need to do this by iterating through all my objects and figure out if I'm touching an object that way or maybe there is an easier more efficient way. How is this usually handled? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesEnded:touches withEvent:event]; UITouch* touch = ([touches count] == 1 ? [touches anyObject] : nil); CGRect bounds = [self bounds]; CGPoint location = [touch locationInView:self]; location.y = bounds.size.height - location.y; float xTouched = location.x/20 - 8 + ((int)location.x % 20)/20; float yTouched = location.y/20 - 12 + ((int)location.y % 20)/20; } typedef struct object_tag // Create A Structure Called Object { int tex; // Integer Used To Select Our Texture float x; // X Position float y; // Y Position float z; // Z Position float yi; // Y Increase Speed (Fall Speed) float spinz; // Z Axis Spin float spinzi; // Z Axis Spin Speed float flap; // Flapping Triangles :) float fi; // Flap Direction (Increase Value) } object;

  • OutOfMemoryException

    - by Andrew
    I have an application that is pretty memory hungry. It holds a large amount of data in some big arrays. I have recently been noticing the occasional OutOfMemoryException. These OutOfMemoryExceptions are occurring long before my application (ASP.Net) has used up the 800mb available to it. I have track the issue down to the area of code where the array is resized. The array contains a structure that is 74bytes in size. (I know that you shouldn't create struct's that are bigger than 16bytes), but this application is a port from a Vb6 application). I have tried changing the struct to a class and this appears to have fixed the problem for now. I think the reason that changing to a class solves the problem has to do with the fact that when using a struct and the array is resized, a segment of memory that is large enough to store the new array needs to be reserved (e.g. (currentArraySize + increaseBySize)*74) cannot be found. This leads to the OutOfMemoryException. This isn't the case with a class as each element of the array only needs 8bytes to store a pointer to the new object. Is my thinking correct here?

  • Centering a div block without the width

    - by Vinicius
    Hi, I have a problem when I try to center the div block "products" because I don't know in advance the div width. Anybody have a solution? Update: The problem I have is I don't know how many products I'll display, I can have 1, 2 or 3 products, I can center them if it was a fixed number as I'd know the width of the parent div, I just don't know how to do it when the content is dynamic. <style> .product_container { text-align: center; height: 150px; } .products { height: 140px; text-align: center; margin: 0 auto; clear: ccc both; } .price { margin: 6px 2px; width: 137px; color: #666; font-size: 14pt; font-style: normal; border: 1px solid #CCC; background-color: #EFEFEF; } </style> <div class="product_container"> <div class="products" id="products"> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> <div id="product_15"> <img src="/images/ecommerce/card_default.png"> <div class="price">R$ 0,01</div> </div> </div> </div>

  • How to count term frequency for set of documents?

    - by ManBugra
    i have a Lucene-Index with following documents: doc1 := { caldari, jita, shield, planet } doc2 := { gallente, dodixie, armor, planet } doc3 := { amarr, laser, armor, planet } doc4 := { minmatar, rens, space } doc5 := { jove, space, secret, planet } so these 5 documents use 14 different terms: [ caldari, jita, shield, planet, gallente, dodixie, armor, amarr, laser, minmatar, rens, jove, space, secret ] the frequency of each term: [ 1, 1, 1, 4, 1, 1, 2, 1, 1, 1, 1, 1, 2, 1 ] for easy reading: [ caldari:1, jita:1, shield:1, planet:4, gallente:1, dodixie:1, armor:2, amarr:1, laser:1, minmatar:1, rens:1, jove:1, space:2, secret:1 ] What i do want to know now is, how to obtain the term frequency vector for a set of documents? for example: Set<Documents> docs := [ doc2, doc3 ] termFrequencies = magicFunction(docs); System.out.pring( termFrequencies ); would result in the ouput: [ caldari:0, jita:0, shield:0, planet:2, gallente:1, dodixie:1, armor:2, amarr:1, laser:1, minmatar:0, rens:0, jove:0, space:0, secret:0 ] remove all zeros: [ planet:2, gallente:1, dodixie:1, armor:2, amarr:1, laser:1 ] Notice, that the result vetor contains only the term frequencies of the set of documents. NOT the overall frequencies of the whole index! The term 'planet' is present 4 times in the whole index but the source set of documents only contains it 2 times. A naive implementation would be to just iterate over all documents in the docs set, create a map and count each term. But i need a solution that would also work with a document set size of 100.000 or 500.000. Is there a feature in Lucene i can use to obtain this term vector? If there is no such feature, how would a data structure look like someone can create at index time to obtain such a term vector easily and fast? I'm not that Lucene expert so i'am sorry if the solution is obvious or trivial.

  • .NET Sockets Buffer Overflow No Error

    - by Michael Covelli
    I have one thread that is receiving data over a socket like this: while (sock.Connected) { // Receive Data (Block if no data) recvn = sock.Receive(recvb, 0, rlen, SocketFlags.None, out serr); if (recvn <= 0 || sock == null || !sock.Connected) { OnError("Error In Receive, recvn <= 0 || sock == null || !sock.Connected"); return; } else if (serr != SocketError.Success) { OnError("Error In Receive, serr = " + serr); return; } // Copy Data Into Tokenizer tknz.Read(recvb, recvn); // Parse Data while (tknz.MoveToNext()) { try { ParseMessageAndRaiseEvents(tknz.Buffer(), tknz.Length); } catch (System.Exception ex) { string BadMessage = ByteArrayToStringClean(tknz.Buffer(), tknz.Length); string msg = string.Format("Exception in MDWrapper Parsing Message, Ex = {0}, Msg = {1}", ex.Message, BadMessage); OnError(msg); } } } And I kept seeing occasional errors in my parsing function indicating that the message wasn't valid. At first, I thought that my tokenizer class was broken. But after logging all the incoming bytes to the tokenizer, it turns out that the raw bytes in recvb weren't a valid message. I didn't think that corrupted data like this was possible with a tcp data stream. I figured it had to be some type of buffer overflow so I set sock.ReceiveBufferSize = 1024 * 1024 * 8; and the parsing error never, ever occurs in testing (it happens often enough to replicate if I don't change the ReceiveBufferSize). But my question is: why wasn't I seeing an exception or an error state or something if the socket's internal buffer was overflowing before I changed this buffer size?

  • "Priming" a whole database in MSSQL for first-hit speed

    - by David Spillett
    For a particular apps I have a set of queries that I run each time the database has been restarted for any reason (server reboot usually). These "prime" SQL Server's page cache with the common core working set of the data so that the app is not unusually slow the first time a user logs in afterwards. One instance of the app is running on an over-specced arrangement where the SQL box has more RAM than the size of the database (4Gb in the machine, the DB is under 1.5Gb currently and unlikely to grow too much relative to that in the near future). Is there a neat/easy way of telling SQL Server to go away and load everything into RAM? It could be done the hard way by having a script scan sysobjects & sysindexes and running SELECT * FROM <table> WITH(INDEX(<index_name>)) ORDER BY <index_fields> for every key and index found, which should cause every used page to be read at least once and so be in RAM, but is there a cleaner or more efficient way? All planned instances where the database server is stopped are out-of-normal-working-hours (all the users are at most one timezone away and unlike me none of them work at silly hours) so such a process (until complete) slowing down users more than the working set not being primed at all would is not an issue.

  • BlackBerry:Reduce space between 2 buttons in HorizontalFieldManager

    - by user469999
    hi In blackberry i have created a horizontal field managar and added some buttons of small size to it to display toolbar at the bottom of the screen.But my problem is there is too much space between the 2 buttons.I have to reduce this space between 2 buttons so that i can manage to place atleast 6 buttons at the bottom of the screen.I am using the BFmsg.setMargin(305,0,0,40) statement. can anyone please help me on this. Following is my code : BFcontacts = new ButtonField("Cnt") { protected void paint(Graphics graphics) { //Bitmap contactsbitmap = Bitmap.getBitmapResource("contacts.jpg"); //graphics.drawBitmap(0, 0, contactsbitmap.getWidth(), contactsbitmap.getHeight(), contactsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Cnt",0,0); } }; BFcontacts.setMargin(305,0,0,10);//vertical pos,0,0,horizontal pos HFM.add(BFcontacts); BFmsg = new ButtonField("Msgs") { protected void paint(Graphics graphics) { //Bitmap msgsbitmap = Bitmap.getBitmapResource("messages.jpg"); //graphics.drawBitmap(0, 0, msgsbitmap.getWidth(), msgsbitmap.getHeight(), msgsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Msgs",0,0); } }; BFmsg.setMargin(305,0,0,40);//vertical pos,0,0,horizontal pos : original HFM.add(BFmsg); add(HFM) Thanks in advance

  • What would be the time complexity of counting the number of all structurally different binary trees?

    - by ktslwy
    Using the method presented here: http://cslibrary.stanford.edu/110/BinaryTrees.html#java 12. countTrees() Solution (Java) /** For the key values 1...numKeys, how many structurally unique binary search trees are possible that store those keys? Strategy: consider that each value could be the root. Recursively find the size of the left and right subtrees. */ public static int countTrees(int numKeys) { if (numKeys <=1) { return(1); } else { // there will be one value at the root, with whatever remains // on the left and right each forming their own subtrees. // Iterate through all the values that could be the root... int sum = 0; int left, right, root; for (root=1; root<=numKeys; root++) { left = countTrees(root-1); right = countTrees(numKeys - root); // number of possible trees with this root == left*right sum += left*right; } return(sum); } } I have a sense that it might be n(n-1)(n-2)...1, i.e. n!

  • Wanted to know in detail about how shared libraries work vis-a-vis static library.

    - by goldenmean
    Hello, I am working on creating and linking shared library (.so). While working with them, many questions popped up which i could not find satisying answers when i searched for them, hence putting them here. The questions about shared libraries i have are: 1.) How is shared library different than static library? What are the Key differences in way they are created, they execute? 2.) In case of a shared library at what point are the addresses where a particular function in shared library will be loaded and run from, given? Who gives those functions is load/run addresses? 3.) Will an application linked against shared library be slower in execution as compared to that which is linked with a static library? 4.) Will application executable size differ in these two cases? 5.) Can one do source level debugging of by stepping into functions defined inside a shared library? Is any thing extra needed to make these functions visible to the application? 6.) What are pros and cons in using either kind of library? Thanks. -AD

  • How do I read binary C++ protobuf data using Python protobuf?

    - by nbolton
    The Python version of Google protobuf gives us only: SerializeAsString() Where as the C++ version gives us both: SerializeToArray(...) SerializeAsString() We're writing to our C++ file in binary format, and we'd like to keep it this way. That said, is there a way of reading the binary data into Python and parsing it as if it were a string? Is this the correct way of doing it? binary = get_binary_data() binary_size = get_binary_size() string = None for i in range(len(binary_size)): string += i message = new MyMessage() message.ParseFromString(string) Update: Here's a new example, and a problem: message_length = 512 file = open('foobars.bin', 'rb') eof = False while not eof: data = file.read(message_length) eof = not data if not eof: foo_bar = FooBar() foo_bar.ParseFromString(data) When we get to the foo_bar.ParseFromString(data) line, I get this error: Exception Type: DecodeError Exception Value: Too many bytes when decoding varint. Update 2: It turns out, that the padding on the binary data was throwing protobuf off; too many bytes were being sent in, as the message suggests (in this case it was referring to the padding). This padding comes from using the C++ protobuf function, SerializeToArray on a fixed-length buffer. To eliminate this, I have used this temproary code: message_length = 512 file = open('foobars.bin', 'rb') eof = False while not eof: data = file.read(message_length) eof = not data string = '' for i in range(0, len(data)): byte = data[i] if byte != '\xcc': # yuck! string += data[i] if not eof: foo_bar = FooBar() foo_bar.ParseFromString(string) There is a design flaw here I think. I will re-implement my C++ code so that it writes variable length arrays to the binary file. As advised by the protobuf documentation, I will prefix each message with it's binary size so that I know how much to read when I'm opening the file with Python.

  • assigning width to li

  • Dynamically Resizing an Iframe

    - by regex
    Hello All, I can see that this question has been asked several times, but none of the proposed solutions seem to work for the site I am building, so I am reopening the thread. I am attempting to size an iframe based on the height of it's content. Both the page that contains the iframe and it's source page exist on the same domain. I have tried the proposed solutions in each of the following threads: Resize iframe height according to content height in it Resizing an iframe based on content I believe that the solutions above are not working because of when the reference to body.clientHeight is made, the browser has not actually determined the height of the document. Here is the code I am using: var ifmBlue = document.getElementById("ifmBlue"); ifmBlue.onload = resizeIframe; function resizeIframe() { var ifmBlue = document.getElementById("ifmBluePill"); var ifmDiv = ifmBlue.contentDocument.getElementById("main"); var height = ifmDiv.clientHeight; ifmBlue.style.height = (ifmBlue.contentDocument.body.scrollHeight || ifmBlue.contentDocument.body.offsetHeight || ifmBlue.contentDocument.body.parentNode.clientHeight || height || 500) + 5 + 'px'; } If I debug the script using fire debug, the client height of the iframe.contentDocument's main div is 0. Additionally, body.offsetHieght, & body.scrollHeight are 0. However, after the script is finished running, if I inspect the DOM of the HTML iframe element (using fire debug) I can see that the body's clientHeight is 456 and the inner div's clientHeight is 742. This leads me to believe that these values are not yet set when iframe.onload is fired. So, per one of the threads above, I moved the code into the body.onload event handler of the iframe's source page. This solution also did not work. Any help you can provide is much appreciated. Thanks, CJ
