  • How can I get a static URL to a map image using the Google Static Maps API?

    - by Argote
    === BACKGROUND === Hello, so I've published a Web-App (still in "Beta") which uses the Flickr API to get information for the photos of a particular Flickr user and generates IPB code to post any of his/her images. While Flickr now gives you the IPB code to show the image and link back to the photo site directly on its site, my App also has the option of embeding the title, description, select EXIF data, location information, etc. into the post for the IPB forum. === PROBLEM === I've most recently added the option to integrate a Google Maps image of the photo's geolocation data into the post by using the Google Static Maps API. The problem is that the image URL I have is in the following form (including IPB [IMG] tags): [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] Which shows this example image (In practice the image size is user selectable): However, some IPB forums seem to not support dyamic image URLs which gives me a broken image, I'd like to replace the [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] with something like [IMG]http://maps.google.com/maps/api/staticmap/map0000001.png[/IMG] which should be supported by all IPB forums. Thanks in advance for your help. In case you're interested, the most recent "released" version of my Web-App can be found here: http://flickr.argote.mx/ (The changes I mention here are still on local development server).

  • How to make gcc on SUN calculate floating points the same way as in Linux

    - by Marina
    I have a project where I have to perform some mathematics calculations with double variables. The problem is that I get different results on SUN Solaris 9 and Linux. There are a lot of ways (explained here and other forums) how to make Linux work as Sun, but not the other way around. I cannot touch the Linux code, so it is only SUN I can change. Is there any way to make SUN to behave as Linux? The code I run(compile with gcc on both systems): int hash_func(char *long_id) { double product, lnum, gold; while (*long_id) lnum = lnum * 10.0 + (*long_id++ - '0'); printf("lnum => %20.20f\n", lnum); lnum = lnum * 10.0E-8; printf("lnum => %20.20f\n", lnum); gold = 0.6125423371582974; product = lnum * gold; printf("product => %20.20f\n", product); ... } if the input is 339886769243483 the output in Linux: lnum => 339886769243**483**.00000000000000000000 lnum => 33988676.9243**4829473495483398** product => 20819503.600158**59827399253845** When on SUN: lnum => 339886769243483.00000000000000000000 lnum => 33988676.92434830218553543091 product = 20819503.600158**60199928283691** Note: The result is not always different, moreover most of the times it is the same. Just 10 15-digit numbers out of 60000 have this problem. Please help!!!

  • Another C question

    - by maddy
    Hi all, I have a piece of code shown below #include <stdio.h> #include <stdlib.h> void Advance_String(char [2],int ); int Atoi_val; int Count22; int Is_Milestone(char [2],int P2); char String[2] = "00"; main() { while(1) { if(Is_Milestone(S,21==1) { if(atoi(S)==22) { Count_22 = Count_22 + 1; } } Atoi_val = atoi(S); Advance_String(S,Atoi_val); } } int Is_Milestone(char P1[2],int P2) { int BoolInit; char *Ptr = P1; int value = atoi(Ptr); BoolInit = (value > P2); return BoolInit; } void Advance_String(char P1[2],int Value) { if(Value!=7) { P1[1] = P1[1]+1; } else { P1[1] = '0'; P1[0] = P1[0]+1 ; } } Now my problem is Count22 never increments as the char increments never achieves the value 21 or above.Could anyone please tell me the reason for this unexpected behaviour?My question here is to find the value of Count22.Is there any problem with the code? Thanks and regards Maddy

  • Symfony dynamic forms

    - by Asier
    Hi there, I started with a form, which is made by hand because of it's complexity (it's a javascript modified form, with sortable parts, etc). The problem is that now I need to do the validation, and it's a total mess to do it from scratch in the action using the sfValidator* classes. So, I am thinking to do it using sfForm so that my form validation and error handling can be done more easier and so I can reuse this form for the Edit and Create pages. The form is something like this: <form> <input name="form[year]"/> <textarea name="form[description]"></textarea> <div class="sortable"> <div class="item"> <input name="form[items][0][name]"/> <input name="form[items][0][age]"/> </div> <div class="item"> <input name="form[items][1][name]"/> <input name="form[items][1][age]"/> </div> </div> </form> The thing is that the sortable part of the form can be expanded from 2 to N elements on the client side. So that it has variable items quantity which can be reordered. How can I approach this problem? Any ideas are welcome, thank you. :)

  • Iphone - UIView not displayed

    - by Raphael Pinto
    Hi, I have a strange problem with a UIView : I want to show an Activity Indicator View that I created with Interface Builder to indicate long running activity. In the viewDidLoad function of my principal viewController I init the ActivityIndicator View like this : - (void)viewDidLoad { [super viewDidLoad]; appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; load = [[ActivityIndicatorViewController alloc] init]; ... When I push a button it call this IBAction : - (IBAction)LaunchButtonPressed{ // Show the Activity indicator view. [self.view addSubview:load.view]; // eavy work [self StartWorking]; // Hide the loading view. [load.view removeFromSuperview]; } In the StartWorking function, I ask a request to an internet serveur and parse the XML file that it return me. The problem is that if I Call my StartWorking function, the application do not start by showing the Activity Indicator view but with the StartWorking function. Whereas if I remove the call to StartWorking function, the view is shown. Is someone able to explain me why? :s

  • Foreach loop returning null values in PHP?

    - by Jascha
    Hello, I have a pretty simple problem. Basically I have an array called $list that is a list of titles. If I do a print_r($list) I get these results: Array ( [0] => Another New Title [1] => Awesome Movies and stuff [2] => Jascha's Title ) Now, I'm running a foreach loop to retrieve their values and format them in an <ul> like so... function get_film_list(){ global $categories; $list = $categories->get_film_list(); if(count($list)==0){ echo 'No films are in this category'; }else{ echo '<ul>'; foreach($list as $title){ echo '<li>' . $title . '<li>'; } echo '</ul>'; } } The problem I'm having is my loop is returning two values per value (is it the key value?) The result of the preceding function looks like this: Another New Title   Awesome Movies and stuff   Jascha's Title   I even tried: foreach($list as $key => $title){ echo '<li>' . $title . '<li>'; } With the same results: Another New Title   Awesome Movies and stuff   Jascha's Title   What am I missing here? Thanks in advance.

  • How to flush DNS cache in Windows Mobile programmatically?

    - by Bounded
    Hello, My windows mobile application (written in C# with the compact framework) needs to know if a particular machine is active or not. To achieve this goal, I thought to use a ping mechanism. I tried to use the Ping class implemented in the opennetcf framework (the System.Net.NetworkInformation.Ping class for the .NET Framework is not part of the compact framework). Because I give to the Ping.Send function a host name, it first tries to resolve this host name and to retrieve an IP address. But i observe the following problem : If the first dns resolution fails (because the network is down at this moment), and if the application tries immediately again to send the ping, it fails too, even if the network is note down anymore. I check with a famous network protocol analyzer and i saw that only the requests concerning the first dns resolution are sent. The requests concerning the dns resolution of the second ping are not sent. Why is the second dns request not sent ? Is there any dns cache mechanism on such Windows Mobile devices ? If yes, can this mechanism beeing flushed programmatically ? EDIT : I gave up finding a solution to this DNS flush. I chose to ping an IP adress instead of a name machine. The problem of pinging an hard coded adress IP is that we have to be 100% sure that this IP will not change. The gateway IP can be used because it's always reachable (if it does not, it means the network is down).

  • Why is Chrome miscalculating jQuery submenu dimensions?

    - by chunkymonkey
    I'm trying to implement this dropdown menu with flyouts: http://jsfiddle.net/chunkymonkey/fr6x4/ In Chrome certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has as many subcategories, shows no subcategories when expanded. (SCREENSHOT: http://i.imgur.com/0WorR.jpg) I thought I had tracked this problem down to a problem with they way the dimensions of the dropdown elements are calculated in the original code: First change: - var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * 180; + var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * container.width(); Second change: Remove: var checkMenuHeight = function(el) { if (el.height() > options.maxHeight) { el.addClass('fg-menu-scroll') }; el.css({ height: options.maxHeight }); }; Add: var checkMenuHeight = function(el) { var max_height = options.maxHeight - breadcrumb.getTotalHeight(); if (el.height() > max_height) { el.addClass('fg-menu-scroll'); el.height(max_height); topList.height(max_height); } else { if (topList.height() < el.height()) { topList.height(el.height()); } } }; But it's still not working only on Chrome (version 8, Windows & Mac) (not sure why Chrome is different).

  • Viewing namespaced global variables in Visual Studio debugger?

    - by Chris
    When debugging a non-managed C++ project in Visual Studio 2008, I occasionally want to see the value of a global variable. We don't have a lot of these but those that are there all declared within a namespace called 'global'. e.g. namespace global { int foo; bool bar; ... } The problem is that when the code is stopped at a breakpoint, the default debugging tooltip (from pointing at the variable name) and quickwatch (shift-f9 on the variable name) don't take the namespace into consideration and hence won't work. So for example I can point at 'foo' and nothing comes up. If I shift-f9 on foo, it will bring up the quickwatch, which then says 'CXX0017: Error: symbol "foo" not found'. I can get around that by manually editing the variable name in the quickwatch window to prefix it with "global::" (which is cumbersome considering you have to do it each time you want to quickwatch), but there is no fix for the tooltip that I can work out. Setting the 'default namespace' of the project properties doesn't help. How can I tell the VS debugger to use the namespace that it already knows the variable is declared in (since it has the declaration right there), or, alternatively, tell it a default namespace to look for variables in if it doesn't find them? My google-fu has failed to find an answer. This report lists the same problem, with MS saying it's "by design", but even so I am hoping there is some way to work around it (perhaps with clever use of autoexp.dat?)

  • Memory leak, again!

    - by Dave
    A couple of weeks ago I was having trouble with memory leaks associated with a ContextMenuStrip. That problem was fixed. See that question here Now I'm having similar issues with ToolStrip controls. As in the previous problem, I'm creating a large number of UserControls and adding them to a FlowLayoutPanel. Each control creates a ToolStrip for itself in its constructor. When a control is removed from the FlowLayoutPanel (the only reference to the control), it seems memory for the ToolStrip is not being released. However when I comment out the code that creates the ToolStrip the memory leak doesn't happen. Is this the same sort of issue as the previous one - I need to set the ToolStrip to null? I don't see how that could be since this time the control is creating the strip itself, and all the button events etc are handled inside it. So shouldn't everything be GC'd when the control is no longer referenced? EDIT: As to the comments, the thing I don't understand is originally I was "making" my own toolstrip out of a panel and some labels. The labels were used as buttons. No memory leaks occurred this way. The only thing I've changed is using a proper ToolStrip with proper buttons in place of the panel, but all the event handlers are wired the same way. So why is it now leaking memory?

  • can I disable the "(Type e to repeat macro)" message in emacs?

    - by lindes
    Hi there, So, I've finally made the plunge, and have gotten to the state where I'm quite happy to have switched from vi and vim to emacs... I've been putting stuff in my .emacs file, learning how to evaluate things (not to mention becoming familiar with movement commands), etc. etc. etc. And now I have a problem with a require line in my .emacs file (a require statement*), which bombs out when I launch emacs (and generally fails to work). So, this lead me to the following situation: In the process of trying to debug the above situation, one of the steps I did was to open the file I was trying to require, and evaluate it bit by bit, using C-M-f and C-x C-e (and later just M-x eval-buffer), which all worked fine. But along the way of the section-by-section, I got tired of typing all those, and so I recorded a keyboard macro... C-x ( C-M-f C-x C-e C-x ) and then C-x e... which gave me a message in the minibuffer (I think I'm using the right name), saying (Type e to repeat macro). Which meant I could no longer see the resultant value of the evaluation of each section of code... which, while not critical in this case, I was liking having. Which leads me to the actual question: Is there a way to disable that message, and/or to cause the minibuffer to show multiple lines at once? I know about the *Messages* buffer, and that could have helped, I'm just wondering if there's a way to either disable that message, or otherwise make it coexist with other messages. Any suggestions? Thanks! lindes * - the problem at hand, which is not really my question, is that (require 'ruby-mode/ruby-mode) fails, even though emacs is definitely and successfully (per system call tracing) opening and reading the ruby-mode.el file. I presume this is because the provide line says just 'ruby-mode. I've found a solution for this, but if anyone can point me to any "best practices", I'd appreciate it.

  • How should child views of UIScrollView report their bounds for contentSize?

    - by Mike
    I'm looking more for advice on the correct design for a view. What I have is a UIScrollView that contains one or more custom Views I have created. My problem is, who reports to the scrollview what it's contentSize should be? I have the following: UIView +-UIScrollView +-CustomView 1 with dynamic height depending on data +-CustomView 2 with dynamic Height depending on data The UIViewController creates new instances of the custom views with data and then adds them as subviews to the UIScrollView. The problem I'm having is how to set the value of the scrollview's contentSize? Right now, I'm not doing that and the contents of the scrollview are clipped with no scrolling possible. Should the custom view call [parent setContentSize:] in its drawRect:? Should the UIViewController query the custom view after creation to get its bounds and then call setContentSize? Should I subclass the UIScrollView to override addSubView to query each subview's height? Is there something else I'm missing? I hope I explained that properly. I'm new to this and still getting a handle on things.

  • Writing a JavaScript zip code validation function

    - by mkoryak
    I would like to write a JavaScript function that validates a zip code, by checking if the zip code actually exists. Here is a list of all zip codes: http://www.census.gov/tiger/tms/gazetteer/zips.txt (I only care about the 2nd column) This is really a compression problem. I would like to do this for fun. OK, now that's out of the way, here is a list of optimizations over a straight hashtable that I can think of, feel free to add anything I have not thought of: Break zipcode into 2 parts, first 2 digits and last 3 digits. Make a giant if-else statement first checking the first 2 digits, then checking ranges within the last 3 digits. Or, covert the zips into hex, and see if I can do the same thing using smaller groups. Find out if within the range of all valid zip codes there are more valid zip codes vs invalid zip codes. Write the above code targeting the smaller group. Break up the hash into separate files, and load them via Ajax as user types in the zipcode. So perhaps break into 2 parts, first for first 2 digits, second for last 3. Lastly, I plan to generate the JavaScript files using another program, not by hand. Edit: performance matters here. I do want to use this, if it doesn't suck. Performance of the JavaScript code execution + download time. Edit 2: JavaScript only solutions please. I don't have access to the application server, plus, that would make this into a whole other problem =)

  • SQL2008 merge replication fails to update depdendent items when table is added

    - by Dan Puzey
    Setup: an existing SQL2008 merge replication scenario. A large server database, including views and stored procs, being replicated to client machines. What I'm doing: * adding a new table to the database * mark the new table for replication (using SP_AddMergeArticle) * alter a view (which is already part of the replicated content) is updated to include fields from this new table (which is joined to the tables in the existing view). A stored procedure is similarly updated. The problem: the table gets replicated to client machines, but the view is not updated. The stored procedure is also not updated. Non-useful workaround: if I run the snapshot agent after calling SP_AddMergeArticle and before updating the view/SP, both the view and the stored procedure changes correctly replicate to the client. The bigger problem: I'm running a list of database scripts in a transaction, as part of a larger process. The snapshot agent can't be run during a transaction, and if I interrupt the transaction (e.g. by running the scripts in multiple transactions), I lose the ability to roll back the changes should something fail. Does anyone have any suggestions? It seems like I must be missing something obvious, because I don't see why the changes to the view/sproc wouldn't be replicating anyway, regardless of what's going on with the new table.

  • MySQL INJECTION Solution...

    - by Val
    I have been bothered for so long by the MySQL injections and was thinking of a way to eliminate this problem all together. I have came up with something below hope that many people will find this useful. The only Draw back I can think of this is the partial search: Jo =returns "John" by using the like %% statement. Here is a php solution: <?php function safeQ(){ $search= array('delete','select');//and every keyword... $replace= array(base64_encode('delete'),base64_encode('select')); foreach($_REQUEST as $k=>$v){ str_replace($search, $replace, $v); } } foo(); function html($str){ $search= array(base64_encode('delete'),base64_encode('select')); $replace= array('delete','select');//and every keyword... str_replace($search, $replace, $str); } //example 1 ... ... $result = mysql_fetch_array($query); echo html($result[0]['field_name']); //example 2 $select = 'SELECT * FROM safeQ($_GET['query']) '; //example 3 $insert = 'INSERT INTO .... value(safeQ($_GET['query']))'; ?> I know, I know that you still could inject using 1=1 or any other type of injections... but this I think could solve half of your problem so the right mysql query is executed. So my question is if anyone can find any draw backs on this then please feel free to comment here. PLEASE GIVE AN ANSWER only if you think that this is a very useful solution and no major drawbacks are found OR you think is a bad idea all together...

  • jQuery UI + Gmaps = Problems (for me at least) HELP!!

    - by Luis
    Hi there! I started using jQuery as soon as I found out about it, it is very powerfull but I started struggling when I tried to load Gmaps api into the tabs jQuery UI brings. Strangly enough in IE 6,7,8 it works fine, but in Firefox, Safari (I'm using mac but tested it in windows and they both give the same problems) the map doesn't load entirely. When I click on the tab where the map loads in, only part of the map is fully operational, the rest is grey and not clickable. Please take a look at the link below and click the third tab in firefox/safari and IE and you will see the problem. http://movewithusoverseas.com/index-new.php?z=product-info.html&pid=1 I don't know if it is a bug in the jQuery UI code or I'm doing something wrong. If I load the map out of the tabs the map is shown OK. I'm fighting with this problem for a week and a half... any help will be much appreciated. Thanks in advance. Luis

    ok im gonna try my best to explain my problem i have this program where u can select 5 balls when u select one you can take it with you while you have the mouse button pressed and its within the ball radius. The problem is that i need a way to make the ball go up when the user stop pressing the mouse button like he sent it to float in the air then make it fall down again i have one way to know the time,velocity and thus the acceleration but i dont know how to implement it... right now i have this void Circulo::caida(float velocidad,float tiempo) { if(this->posY >= 580) { this->posY = 580; this->vcaida = 0.0f; } else if(this->posY < 580) { //this->distancia=9.81f * 0.5f*tiempo*tiempo; this->vcaida += velocidad; this->posY += this->vcaida; } } with this like this it just falls and i cant make the effect i tried to explain... thank you i hope someone can help me .< oh yeah im calculating the time like this just in case it helps difX=(x> evento.motion.xrel)? x-evento.motion.xrel : evento.motion.xrel-x; difY=(y> evento.motion.yrel)? y-evento.motion.yrel : evento.motion.yrel-y; and im sending difY as the time variable

  • Easy bidirectional communication via P2P NetStream

    - by andsve
    I've been looking into the P2P support in Flash 10, using Adobe Stratus service. I have successfully been able to send data from one user to another, put my problem is that I haven't figured out how to send data back in some easy way (or as some kind of response to the first call). What I'm currently doing; First set up a connection with Stratus service nc = new NetConnection(); nc.addEventListener(NetStatusEvent.NET_STATUS, ncStatusHandler); nc.connect(APPLICATION_URL + DEVELOPER_KEY); On the "server" side I do: sendStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS); sendStream.addEventListener(NetStatusEvent.NET_STATUS, sendStreamHandler); sendStream.publish("file"); And on the "client" side: // remoteFileID.text is manually copied by the user from the server (which is nc.nearID). recvStream = new NetStream(nc, remoteFileID.text); recvStream.client = this; recvStream.addEventListener(NetStatusEvent.NET_STATUS, recvStreamHandler); recvStream.play("file"); Then I call a remote function on the client: ... sendStream.send("aRemoteFunction", parameterData); ... Now my problem; I want to do the same from the client to the server, to notify that everything went well, or something failed. From what I understand, I will have to setup a new NetStream from the client to the server (i.e publish on the client and play on the server). But to accomplish this, the server need to know the nc.nearID on the client. Is it possible to get that ID without forcing the user to manually copy it from the client to server? Or, is there an easier way for the client to talk back to the server that I am missing?

  • Delphi: how to lock dfm-s to not change...?

    - by durumdara
    Hi! We used Delphi 6 long times ago. Our problem, that Delphi have two problems with DFMs: 1.) When some linked resource (like DataSet) will removed, Delphi many times forget to ask you that "some of the resources are linked, you need to redirect...". This happens, when the actual form is not added to the project, or it is not opened. 2.) When we only open the DFM, and only see some thing, may we change it (active TabSheet, form position). Then Delphi auto save the form - and sometimes it drops the links. Another problem with this that we used SVN, and SVN detect these changes... We thought that we change DFM files to read only, but this can prevent the usage of SVN too... So somebody please help us: have the Delphi some extension (like gexpert) that can lock the DFMs to avoid changes, and some other tool to see that dataset is used in other forms or not? Thanks for your help: dd

  • SQL Server becomes slow after restart

    - by Tobi DM
    We use SQL Server 2005 on an Windwos Server 2008. Ther Server has 48 GB RAM. SQL Server is configured to use 40 GB RAM. There is only one database hosted (About 70 GB). The only app beside SQL Server is our App-Server which connects the clients to the database. Now we encounter the following problem: After a restart of the server our the performance is great. The server grabs the 40 GB RAM wich it is allowed to and then runs fast as hell. But after about 4 weeks the system becomes slower and slower. The execution of statements (seen in the profiler) is raising slowly. But I cannot see that there is something going wrong on the server. CPU usage is at about 20% I/O also seems to be no Problem The process monitor does also not show that there are strange apps or something like that. Eventlog does also have no interessting messages No open transactions or blockings to see We tried already the following things without effect: Droped the cache by using the statements DBCC FreeProcCache DBCC FREESYSTEMCACHE('ALL') DBCC DropCleanbuffers Restarted the Appserver we are using. Restart the sql server service But nothing did help exept restarting the whole server. Any ideas?

  • is it possible to write a method which creates a method?

    - by Alan Bennett
    hey guys, this might seem like a no brainer but hopefully after i explain my problem you might understand why i am asking this. is it possible to have a method which creates a method and its arguements? the problem: in my current project i have to many times call different sql statements which arent all that different. for example i have one where i inserts some new rows but only has 2 columns and another which also inserts new rows but has 12 columns. i have created a class called utils.cs and in there i have sorted many "handy" methods, such as validation methods which check for numeric input to text boxes etc. so i thought well instead of having sql writing methods everywhere ill make one in there and call it when i need to so i have but it currently looks like this: public static string getInsertSQL(string tablename, string colOne, string colTwo, string colThree, string colFour, string colFive, string colSix, string colSeven, string colEight, string colNine, string colTen, string colEleven, string colTwelve,bool active, string valueOne, string valueTwo, string valueThree, string valueFour, string valueFive, string valueSix, string valueSeven, string valueEight, string valueNine, string valueTen, string valueEleven) { string strSQL = ""; strSQL += "INSERT INTO " + tablename; strSQL += "(" + colOne + " " + colTwo + " " + colThree + " " + colFour + " " + colFive + " " + colSix + " " + colSeven + " " + colEight + " " + colNine + " " + colTen + " " + colEleven + " " + colTwelve + " )"; strSQL += " values ("+active+", " + valueOne + " " + valueTwo + " " + valueThree + " " + valueFour + " " + valueFive + " " + valueSix + " " + valueSeven + " " + valueEight + " " + valueNine + " " + valueTen + " " + valueEleven + " )"; return strSQL; } as you can see thats quite a mess so i wondered if it was at all possible to write a method which would take an arguement of how many colums needed to be inserted and then could create a method with that many arguements. i hope you can see what i am getting at and dont just sound like a plep! thanks in advance

I also want to save certain things like who created the SystemUser and who last modified the system User as well. @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoCreated; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeCreated; @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoLastModified; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeLastModified; I also want to ensure that these values are not null when persisted. So If I use the NotNull JPA annotation, that is easily solved (along with reference to another entity) The problem description is simple, I cannot save rootuser without having rootuser in the system if I am to use a DataLoader class to persist JPA entity. Every other later user can be easily persisted with userWhoModified as the "systemuser" , but systemuser it's self cannot be added in this scheme. Is there a way so persist this first system user (I am thinking with SQL). This is a typical bootstrap (chicken or the egg) problem i suppose.

  • Entity Framework - Insert/Update new entity with child-entities

    - by Christina Mayers
    I have found many questions here on SO and articles all over the internet but none really tackled my problem. My model looks like this (I striped all non essential Properties): Everyday or so "Play" gets updated (via a XML-file containing the information). internal Play ParsePlayInfo(XDocument doc) { Play play = (from p in doc.Descendants("Play") select new Play { Theatre = new Theatre() { //Properties }, //Properties LastUpdate = DateTime.Now }).SingleOrDefault(); var actors = (from a in doc.XPathSelectElement(".//Play//Actors").Nodes() select new Lecturer() { //Properties }); var parts = (from p in doc.XPathSelectElement(".//Play//Parts").Nodes() select new Part() { //Properties }).ToList(); foreach (var item in parts) { play.Parts.Add(item); } var reviews = (from r in doc.XPathSelectElement(".//Play//Reviews").Nodes() select new Review { //Properties }).ToList(); for (int i = 0; i < reviews.Count(); i++) { PlayReviews pR = new PlayReviews() { Review = reviews[i], Play = play, //Properties }; play.PlayReviews.Add(pR); } return play; } If I add this "play" via Add() every Childobject of Play will be inserted - regardless if some exist already. Since I need to update existing entries I have to do something about that. As far as I can tell I have the following options: add/update the child entities in my PlayRepositories Add-Method restructure and rewrite ParsePlayInfo() so that get all the child entities first, add or update them and then create a new Play. The only problem I have here is that I wanted ParsePlayInfo() to be persistence ignorant, I could work around this by creating multiple parse methods (eg ParseActors() ) and assign them to play in my controller (I'm using ASP.net MVC) after everything was parsed and added Currently I am implementing option 1 - but it feels wrong. I'd appreciate it if someone could guide me in the right direction on this one.

  • Microsoft Reporting: Setting subreport parameters in code

    - by Svish
    How can I set a parameter of a sub-report? I have successfully hooked myself up to the SubreportProcessing event, I can find the correct sub-report through e.ReportPath, and I can add datasources through e.DataSources.Add. But I find no way of adding report parameters?? I have found people suggesting to add them to the master report, but I don't really want to do that, since the master report shouldn't have to be connected to the sub-report at all, other than that it is wrapping the sub-report. I am using one report as a master template, printing name of the report, page numbers etc. And the subreport is going to be the report itself. And if I could only find a way to set those report parameters of the sub-report I would be good to go... Clarification: Creating/Defining the parameters is not the problem. The problem is to set their values. I thought the natural thing to do was to do it in the SubreportProcessing event. And the SubreportProcessingEventArgs do in fact have a Parameters property. But it is read only! So how do you use that? How can I set their value?

  • Any high-level languages that can use c libraries?

    - by Isaiah
    I know this question could be in vain, but it's just out of curiosity, and I'm still much a newb^^ Anyways I've been loving python for some time while learning it. My problem is obviously speed issues. I'd like to get into indie game creation, and for the short future, 2d and pygame will work. But I'd eventually like to branch into the 3d area, and python is really too slow to make anything 3d and professional. So I'm wondering if there has ever been work to create a high-level language able to import and use c libraries? I've looked at Genie and it seems to be able to use certain libraries, but I'm not sure to what extent. Will I be able to use it for openGL programing, or in a c game engine? I do know some lisp and enjoy it a lot, but there aren't a great many libraries out there for it. Which leads to the problem: I can't stand C syntax, but C has libraries galore that I could need! And game engines like irrlicht. Is there any language that can be used in place of C around C? Thanks so much guys
