  • Send SOAP XML via curl, PHP

    - by danrichardson
    Hi. This has been bugging me for days, i'm trying to send a SOAP post via curl but i just keep getting a 'couldn't connect to host' error but i really cant see how. I have an asp version which works fine with the same url and data, i think it's just a php/curl thing...? I currently have the following code (the CURLOPT_POSTFIELDS data is a valid soap envelope string) $soap_do = curl_init(); curl_setopt($soap_do, CURLOPT_URL, "https://xxx.yyy.com:517/zzz.asmx" ); curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($soap_do, CURLOPT_TIMEOUT, 10); curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true ); curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($soap_do, CURLOPT_POST, true ); curl_setopt($soap_do, CURLOPT_POSTFIELDS, '<soap:Envelope>...</soap:Envelope>'); curl_setopt($soap_do, CURLOPT_HTTPHEADER, array('Content-Type: text/xml; charset=utf-8', 'Content-Length: '.strlen('<soap:Envelope>...</soap:Envelope>') )); if(curl_exec($soap_do) === false) { $err = 'Curl error: ' . curl_error($soap_do); curl_close($soap_do); return $err; } else { curl_close($soap_do); return 'Operation completed without any errors'; } So any ideas why it just errors all the time? The asp version works fine! The code is; Set xmlhttp = server.Createobject("MSXML2.ServerXMLHTTP") xmlhttp.Open "POST","https://xxx.yyy.com:517/zzz.asmx" xmlhttp.setRequestHeader "Content-Type", "text/xml; charset=utf-8" xmlhttp.Send('<soap:Envelope>...</soap:Envelope>')

  • C++: best way to implement globally scoped data

    - by bobobobo
    I'd like to make program-wide data in a C++ program, without running into pesky LNK2005 errors when all the source files #includes this "global variable repository" file. I have 2 ways to do it in C++, and I'm asking which way is better. The easiest way to do it in C# is just public static members. C#: public static class DataContainer { public static Object data1 ; public static Object data2 ; } In C++ you can do the same thing C++ global data way#1: class DataContainer { public: static Object data1 ; static Object data2 ; } ; Object DataContainer::data1 ; Object DataContainer::data2 ; However there's also extern C++ global data way #2: class DataContainer { public: Object data1 ; Object data2 ; } ; extern DataContainer * dataContainer ; // instantiate in .cpp file In C++ which is better, or possibly another way which I haven't thought about? The solution has to not cause LNK2005 "object already defined" errors.

  • Coding Practices which enable the compiler/optimizer to make a faster program.

    - by EvilTeach
    Many years ago, C compilers were not particularly smart. As a workaround K&R invented the register keyword, to hint to the compiler, that maybe it would be a good idea to keep this variable in an internal register. They also made the tertiary operator to help generate better code. As time passed, the compilers matured. They became very smart in that their flow analysis allowing them to make better decisions about what values to hold in registers than you could possibly do. The register keyword became unimportant. FORTRAN can be faster than C for some sorts of operations, due to alias issues. In theory with careful coding, one can get around this restriction to enable the optimizer to generate faster code. What coding practices are available that may enable the compiler/optimizer to generate faster code? Identifying the platform and compiler you use, would be appreciated. Why does the technique seem to work? Sample code is encouraged. Here is a related question [Edit] This question is not about the overall process to profile, and optimize. Assume that the program has been written correctly, compiled with full optimization, tested and put into production. There may be constructs in your code that prohibit the optimizer from doing the best job that it can. What can you do to refactor that will remove these prohibitions, and allow the optimizer to generate even faster code? [Edit] Offset related link

  • Are Dynamic Prepared Statements Bad? (with php + mysqli)

    - by John
    I like the flexibility of Dynamic SQL and I like the security + improved performance of Prepared Statements. So what I really want is Dynamic Prepared Statements, which is troublesome to make because bind_param and bind_result accept "fixed" number of arguments. So I made use of an eval() statement to get around this problem. But I get the feeling this is a bad idea. Here's example code of what I mean // array of WHERE conditions $param = array('customer_id'=>1, 'qty'=>'2'); $stmt = $mysqli->stmt_init(); $types = ''; $bindParam = array(); $where = ''; $count = 0; // build the dynamic sql and param bind conditions foreach($param as $key=>$val) { $types .= 'i'; $bindParam[] = '$p'.$count.'=$param["'.$key.'"]'; $where .= "$key = ? AND "; $count++; } // prepare the query -- SELECT * FROM t1 WHERE customer_id = ? AND qty = ? $sql = "SELECT * FROM t1 WHERE ".substr($where, 0, strlen($where)-4); $stmt->prepare($sql); // assemble the bind_param command $command = '$stmt->bind_param($types, '.implode(', ', $bindParam).');'; // evaluate the command -- $stmt->bind_param($types,$p0=$param["customer_id"],$p1=$param["qty"]); eval($command); Is that last eval() statement a bad idea? I tried to avoid code injection by encapsulating values behind the variable name $param. Does anyone have an opinion or other suggestions? Are there issues I need to be aware of?

  • pdf external streams in Max OS X Preview

    - by olpa
    According to the specification, a part of a PDF document can reside in an external file. An example for an image: 2 0 obj << /Type /XObject /Subtype /Image /Width 117 /Height 117 /BitsPerComponent 8 /Length 0 /ColorSpace /DeviceRGB /FFilter /DCTDecode /F (pinguine.jpg) >> stream endstream endobj I found that this functionality does work in Adobe Acrobat 5.0 for Windows (sample PDF with the image), also I managed to view this file in Adobe Acrobat Reader 8.1.3 for Mac OS X after I found the setting "Allow external content". Unfortunately, it seems that non-Adobe tools ignore the external stream feature. I hope I'm wrong, therefore ask the question: How to enable external streams in Mac OS X? (I think that all the system Mac OS X tools use the same library, therefore say "Mac OS X" instead of "Preview".) Or maybe there could be a programming hook to emulate external streams? My task is: store a big set of images (total ˜300Mb) outside of a small PDF (˜1Mb). At some moment, I want to filter PDF through a quartz filter and get a PDF with the images embedded. Any suggestions are welcome.

  • Why is Firefox prompting to download a file that is POST'd to?

    This is the most peculiar thing. It is from an old in house CMS. When I attempt to submit my changes, it prompts to save the file linked in the action attribute of the form.

  • scanf segfaults and various other anomalies inside while loop

    - by Shadow
    while(1){ //Command prompt char *command; printf("%s>",current_working_directory); scanf("%s",command);<--seg faults after input has been received. printf("\ncommand:%s\n",command); } I am getting a few different errors and they don't really seem reproducible(except for the segfault at this point .<). This code worked fine about 10 minutes ago, then it infinite looped the printf command and now it seg faults on the line mentioned above. The only thing I changed was scanf("%s",command); to what it currently is. If I change the command variable to be an array it works, obviously this is because the storage is set aside for it. 1) I got prosecuted about telling someone that they needed to malloc a pointer* (But that usually seems to solve the problem such as making it an array) 2) the command I am entering is "magic" 5 characters so there shouldn't be any crazy stack overflow. 3) I am running on mac OSX 10.6 with newest version of xCode(non-OS4) and standard gcc 4) this is how I compile the program: gcc --std=c99 -W sfs.c Just trying to figure out what is going on. Being this is for a school project I am never going to have to see again, I will just code some noob work around that would make my boss cry :) But for afterwards I would love to figure out why this is happening and not just make some fix for it, and if there is some fix for it why that fix works.

  • Reporting Services - can't group by a column called "LanguageId"

    - by marc_s
    Folks, I have a really odd behavior here: I have a SQL Server 2008 Reporting Services report which gets grouped and sorted dynamically. One of the column in my data set which I display is called LanguageId and I was trying to get a grouping going by this LanguageId field. I checked, double-checked and triple-checked the data being returned - it does contain my expected values for LanguageId and everything seems fine and dandy. It just never worked - I didn't get the expected groups, I got things like a specific node actually changing its display value from one ID to another when expanding its subitems, and other really whacky stuff. I discovered that grouping and sorting by LanguageCaption works just fine. It also started working fine after I renamed LanguageId to MyLanguageId. So where on earth is this documented that LanguageId appears to be a system variable / reserved word / keyword of some sort in SQL Server Reporting Services that must be avoided at all costs?? I can't seem to find anything on that topic - even Mr. Google and Mrs. Bing came up empty so far....

  • Converting ntext to nvcharmax(max) - Getting around size limitation

    - by Overflew
    Hi all, I'm trying to change an existing SQL NText column to nvcharmax(max), and encountering an error on the size limit. There's a large amount of existing data, some of which is more than the 8k limit, I believe. We're looking to convert this, so that the field is searchable in LINQ. The 2x SQL statements I've tried are: update Table set dataNVarChar = convert(nvarchar(max), dataNtext) where dataNtext is not null update Table set dataNVarChar = cast(dataNtext as nvarchar(max)) where dataNtext is not null And the error I get is: Cannot create a row of size 8086 which is greater than the allowable maximum row size of 8060. This is using SQL Server 2008. Any help appreciated, Thanks. Update / Solution: The marked answer below is correct, and SQL 2008 can change the column to the correct data type in my situation, and there are no dramas with the LINQ-utilising application we use on top of it: alter table [TBL] alter column [COL] nvarchar(max) I've also been advised to follow it up with: update [TBL] set [COL] = [COL] Which completes the conversion by moving the data from the lob structure to the table (if the length in less than 8k), which improves performance / keeps things proper.

  • adding an uncertain number of fields using javascript

    - by user306472
    I'm new to javascript and a novice programmer, so this might be a really easy question to answer. I would like to loop over the values of x number of fields and add them up to display the sum in a final field. I can perform this function if I explicitly call each field, but I want to abstract this so I can deal with a flexible number of fields. Here's example code I've come up with (that's not working for me). Where am I going wrong? <html> <head> <script type="text/javascript"> function startAdd(){ interval = setInterval("addfields()",1); } function addfields(){ a = document.addition.total.value; b = getElementByTagName("sum").value; for (i=0; i<=b.length; i++){ a+=i; } return a; } function stopAdd(){ clearInterval(interval); } </script> </head> <body> <form name="addition"> <input type="text" name="sum" onFocus="startAdd();" onBlur="stopAdd;"> + <input type="text" name="sum" onFocus="startAdd();" onBlur="stopAdd;"> = <input type="text" name ="total"> </form> </body> </html>

  • Python re module becomes 20 times slower when called on greater than 101 different regex

    - by Wiil
    My problem is about parsing log files and removing variable parts on each lines to be able to group them. For instance: s = re.sub(r'(?i)User [_0-9A-z]+ is ', r"User .. is ", s) s = re.sub(r'(?i)Message rejected because : (.*?) \(.+\)', r'Message rejected because : \1 (...)', s) I have about 120+ matching rules like those above. I have found no performances issues while searching successively on 100 different regex. But a huge slow down comes when applying 101 regex. Exact same behavior happens when replacing my rules set by for a in range(100): s = re.sub(r'(?i)caught here'+str(a)+':.+', r'( ... )', s) Got 20 times slower when putting range(101) instead. # range(100) % ./dashlog.py file.bz2 == Took 2.1 seconds. == # range(101) % ./dashlog.py file.bz2 == Took 47.6 seconds. == Why such thing is happening ? And is there any known workaround ? (Happens on Python 2.6.6/2.7.2 on Linux/Windows.)

  • How to map combinations of things to a relational database?

    - by Space_C0wb0y
    I have a table whose records represent certain objects. For the sake of simplicity I am going to assume that the table only has one row, and that is the unique ObjectId. Now I need a way to store combinations of objects from that table. The combinations have to be unique, but can be of arbitrary length. For example, if I have the ObjectIds 1,2,3,4 I want to store the following combinations: {1,2}, {1,3,4}, {2,4}, {1,2,3,4} The ordering is not necessary. My current implementation is to have a table Combinations that maps ObjectIds to CombinationIds. So every combination receives a unique Id: ObjectId | CombinationId ------------------------ 1 | 1 2 | 1 1 | 2 3 | 2 4 | 2 This is the mapping for the first two combinations of the example above. The problem is, that the query for finding the CombinationId of a specific Combination seems to be very complex. The two main usage scenarios for this table will be to iterate over all combinations, and the retrieve a specific combination. The table will be created once and never be updated. I am using SQLite through JDBC. Is there any simpler way or a best practice to implement such a mapping?

  • Which Stroustrup book should I use?

    - by Chris Simmons
    I'm a C# programmer that is looking to branch out. I'm bored of writing business software and want to start getting into graphics programming and games/simulators. So I figured, although writing that stuff isn't impossible in managed code, the "right" way to do that would be to look to C++, of course focussing on the language first, then getting into OpenGL or DirectX (or whatever). Way way back ('98? '99?) I had tried and failed to really grasp Stroustrup's The C++ Programming Language. I know that this book is often not recommended for the beginner. Anyway, I picked it back up (in a much more recent printing) and I'm actually getting it and enjoying it. I also have a copy of his textbook, Programming: Principles and Practice Using C++, which, as I understand it, is really geared toward teaching programming, not necessarily C++. I'm certainly not arrogant enough to claim I don't have anything more to learn about programming, data structures, algoriths, etc., however I'm not a novice there either. So my question is, with the goal of gaining the broader and more real-world-useful understanding of C++ and given my background, on which should I focus? The denser (as I perceive it) TCPPPL or the gentler Programming? EDIT: I thank everyone for the responses. However, I've got a personal choice here to make between these two books. Granted there are other very good books out there, but I'm already a good length into both of the books I mention and I'd like to finish one. So, can anyone respond on which would be the better and why? Time is not an issue; I'm not looking (at this point) at an "accelerated" read.

  • C++ destructors causing crash's

    - by larsonator
    ok, so i got a some what intricate program that simulates the uni systems of students, units, and students enrolling in units. Students are stored in a binary search tree, Units are stored in a standard list. Student has a list of Unit Pointers, to store which units he/she is enrolled in Unit has a list of Student pointers, to store students which are enrolled in that unit. The unit collections (storing units in a list) as made as a static variable where the main function is, as is the Binary search tree of students. when its finaly time to close the program, i call the destructors of each. but at some stage, during the destructors on the unit side, Unhandled exception at 0x002e4200 in ClassAllocation.exe: 0xC0000005: Access violation reading location 0x00000000.

  • most efficient method of turning multiple 1D arrays into columns of a 2D array

    - by Ty W
    As I was writing a for loop earlier today, I thought that there must be a neater way of doing this... so I figured I'd ask. I looked briefly for a duplicate question but didn't see anything obvious. The Problem: Given N arrays of length M, turn them into a M-row by N-column 2D array Example: $id = [1,5,2,8,6] $name = [a,b,c,d,e] $result = [[1,a], [5,b], [2,c], [8,d], [6,e]] My Solution: Pretty straight forward and probably not optimal, but it does work: <?php // $row is returned from a DB query // $row['<var>'] is a comma separated string of values $categories = array(); $ids = explode(",", $row['ids']); $names = explode(",", $row['names']); $titles = explode(",", $row['titles']); for($i = 0; $i < count($ids); $i++) { $categories[] = array("id" => $ids[$i], "name" => $names[$i], "title" => $titles[$i]); } ?> note: I didn't put the name = value bit in the spec, but it'd be awesome if there was some way to keep that as well.

  • Apache ReWriteEngine throwing 500 Internal Server Error for too many internal redirects... why?!?!?!

    - by Stephen G
    I'm trying to implement a new ReWrite rule on my local dev machine. I have 13 rules set up already, and all work fine (even as of this writing). However, for some reason the newest one is throwing me 500 Internal Server Errors. The ReWrite rule is: RewriteRule stuff/public_html/vault/mystuff/view/(.*) /stuff/public_html/vault/mystuff/view/index.php?stuff=$1 RewriteRule stuff/public_html/vault/mystuff/view/(.*)/ /stuff/public_html/vault/mystuff/view/index.php?stuff=$1 Checked my apache logs and got this: [Thu Jan 13 22:07:43 2011] [error] [client ::1] mod_rewrite: maximum number of internal redirects reached. Assuming configuration error. Use 'RewriteOptions MaxRedirects' to increase the limit if neccessary., referer: http://localhost:8888/stuff/public_html/vault/mystuff/all/index.php?curr=7 On the script I am trying to redirect to view/index.php?stuff=$1, there is nothing that even remotely resembles a redirect of any kind. I do have a very, very basic session verifier being called at the top of the landing script, which is as follows: //Start session session_start(); //Check whether the session variable SESS_MEMBER_ID is present or not if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) { header("location: ".$root_http.""); exit(); } However, when I access the page directly, it acts as it should, and there is no redirect. All of my other ReWrite rules and their corresponding landing pages are set up the exact same way. This is blowing my mind. Any help, PLEASE!?

  • How to specify MQ channel table location for .net web application using web.config

    - by Matt
    I've been going around in circles for a while on this one now. I'm trying to connect to a distributed queue manager using a supplied channel table file. I can get this to work if I specify the environmental variable MQCHLLIB and MQCHLTAB on my server. However the IBM documentation states that the .net config file can override these variables. Here is what I have placed in my web.config file: ... <configSections> <section name="CHANNELS" type="System.Configuration.NameValueSectionHandler" /> </configSections> <CHANNELS> <add key="ChannelDefinitionDirectory" value="C:\temp"></add> <add key="ChannelDefinitionFile" value="DSM_MOM_TEST.tab"></add> </CHANNELS> ... And here is the code that is executing: Hashtable properties = new Hashtable(); //Add managed connection type to parameters. const String connectionType = MQC.TRANSPORT_MQSERIES_CLIENT; properties.Add(MQC.TRANSPORT_PROPERTY, connectionType); return new MQQueueManager(queueManagerName, properties); queueManagerName is set to the generic queue manager "*Q101T". However this isn't working and I get an error returned: 2058 MQRC_Q_MGR_NAME_ERROR I've been unable to find any more documentation on how to get this to work other than the environmental variables and the standard mqclient.ini should be overriden by the channels stanza in the web.config. Is there something that I've missed in the code? Any tips would be greatly appreciated.

    I'm trying to get the filenames in a folder inside a listview(that listview is inside a layout of a ViewPager) but i'm getting a NullPointerException and i can't figure what's wrong. public void citire() { ListView lv1 = (ListView) findViewById(R.id.lv1); myList = new ArrayList<String>(); File directory = Environment.getExternalStorageDirectory(); file = new File(directory + "/InterSRL"); File list[] = file.listFiles(); for (int i = 0; i < list.length; i++) { myList.add(list[i].getName()); } ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, myList); lv1.setAdapter(adapter); } I'm getting the error at lv1.setAdapter(adapter); 06-28 13:10:57.987: E/AndroidRuntime(30450): Caused by: java.lang.NullPointerException 06-28 13:10:57.987: E/AndroidRuntime(30450): at com.example.testlayout.Gestionare.citire(Gestionare.java:169) 06-28 13:10:57.987: E/AndroidRuntime(30450): at com.example.testlayout.Gestionare.onCreate(Gestionare.java:33) 06-28 13:10:57.987: E/AndroidRuntime(30450): at android.app.Activity.performCreate(Activity.java:5104) 06-28 13:10:57.987: E/AndroidRuntime(30450): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1080) 06-28 13:10:57.987: E/AndroidRuntime(30450): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2144)

  • How to get OCI lib to work on red hat machine to work with R Oracle?

    - by Matt Bannert
    I need to get OCI lib working on my rhel 6.3 machine and I am experiencing some trouble with OCI headers files that can't be found. I have installed (using yum install) oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm because this official page it's all I need to run OCI. To test the whole thing in general I've installed sqplus64, which worked after I set export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib. Unfortunately the headers files couldn't be found after setting LD_LIBRARY_PATH. Actually I am not surprised because there is no include directory in any of these oracle paths. So the question is: Where do I get these missing header files from? Are they actually already there and I just can find them? Btw: I am doing this whole exercise because I want to use ROracle on my R Studio server and this R package depends on the OCI library. Once I am back in R territory the road gets much less bumpier for me. EDIT: this documentation helped me a little further. However, I guess I found some header files now in: "/usr/include/oracle/11.2/client64". But which variable do I have to set to this location?

  • jquery.append() - only the last element of my list is appended, previous ones are erased

    - by jaes
    Hi, I have a page like this : <div id="daysTable"> <div id="day0" class="day"></div> <div id="day1" class="day"></div> <div id="day2" class="day"></div> <div id="day3" class="day"></div> <div id="day4" class="day"></div> <div id="day5" class="day"></div> <div id="day6" class="day"></div> </div> and some javascript to fill my calendar like this function getWeek(){ $.getJSON("/getWeek",function(events){ var eventHeight = $("#hoursTable > div").height(); var eventWidth = $("#daysTable > div").width(); var startWeek = events[0]// timestamp of the start of the week for(var i = 1; i < events.length; i ++){ $(".day").empty(); var startHour = (events[i].startDate - startWeek)/3600 var duration = (events[i].stopDate - startWeek)/3600 - startHour var dayStart = Math.floor(startHour/24); var startHour = startHour - dayStart * 24 divEvent = $('<div id="event'+events[i].idEvent+'"/>') .width(eventWidth-2) .height(duration*eventHeight) .css("border","1px solid black") .css("margin-top",startHour*eventHeight) .html(events[i].name); divEvent.appendTo("#day"+dayStart); console.log(divEvent); } }); } my problem being : events contain 3 element I'd like to display but only the last is displayed. If I stop my "for" at the first iteration I can see the first div appended, but it seems that if my loop goes for three iteration the two previous are deleted. The console.log() display some "not-anymore" existing element. Any idea ?

  • Google AJAX Transliteration API :- How do i translate many elements in page to some language at one

    - by Nitesh Panchal
    Hello, I have many elements on page and all of which i want to translate to some language. The language is not the same for all fields, that is, for 1st field it may be fr and for third field it may be en then again for 7th field it may be pa. Basically i wrote the code and it's working :- <script type="text/javascript"> //<![CDATA[ google.load("language", "1"); window.onload = function(){ var elemPostTitles = document.getElementsByTagName("h4"); var flag = true; for(var i = 0 ; i < elemPostTitles.length ; i++){ while(flag == false){ } var postTitleElem = elemPostTitles[i]; var postContentElem = document.getElementById("postContent_" + i); var postTitle = postTitleElem.innerHTML; var postContent = postContentElem.innerHTML; var languageCode = document.getElementById("languageCode_" + i).value; google.language.detect(postTitle, function(result) { if (!result.error && result.language) { google.language.translate(postTitle, result.language, languageCode, function(result) { flag = true; if (result.translation) { postTitleElem.innerHTML = result.translation; } }); } }); flag = false; } As you can see, what i am trying to do is restrict the loop from traversing until the result of previous ajax call is receieved. If i don't do this only the last field gets translated. My code works nicely, but because of the infinite loop, i keep getting errors from Mozilla to "stop executing scripts". How do i get rid of this? Also, is my approach correct? Or some inbuilt function is available which can ease my task? Thanks in advance :)

  • How to run setInterval() on multiple canvases simultaneously?

    - by Alex
    I have a page which has several <canvas> elements. I am passing the canvas ID and an array of data to a function which then grabs the canvas info and passes the data onto a draw() function which in turn processes the given data and draws the results onto the canvas. So far, so good. Example data arrays; $(function() { setup($("#canvas-1"), [[110,110,100], [180,180,50], [220,280,80]]); setup($("#canvas-2"), [[110,110,100], [180,180,50], [220,280,80]]); }); setup function; function setup(canvas, data) { ctx = canvas[0].getContext('2d'); var i = data.length; var dimensions = { w : canvas.innerWidth(), h : canvas.innerHeight() }; draw(dimensions, data, i); } This works perfectly. draw() runs and each canvas is populated. However - I need to animate the canvas. As soon as I replace line 8 of the above example; draw(dimensions, data, i); with setInterval( function() { draw(dimensions, data, i); }, 33 ); It stops working and only draws the last canvas (with the others remaining blank). I'm new to both javascript and canvas so sorry if this is an obvious one, still feeling my way around. Guidance in the right direction much appreciated! Thanks.
