  • iPhone scrolling the view up when keyboard is open

    - by Rob
    I understand that this problem is incredibly common and I have read through quite a few answers but am having trouble understanding how the code works. This works: -(void)textFieldDidBeginEditing:(UITextField *)sender { if ([sender isEqual:txtLeaveAddyLine1]) { //move the main view, so that the keyboard does not hide it. if (self.view.frame.origin.y >= 0) { [self setViewMovedUp:YES]; } } } In this example, txtLeaveAddy is the very first UITextField that is hidden by the keyboard and it works like a charm. As I cycle through the text fields on the screen it scrolls up when the user enters into that txtLeaveAddyLine1 field. However, when I try to add the fields below the txtLeaveAddyLine1 field - nothing happens. For example: -(void)textFieldDidBeginEditing:(UITextField *)sender { if ([sender isEqual:txtLeaveAddyLine1]) { //move the main view, so that the keyboard does not hide it. if (self.view.frame.origin.y >= 0) { [self setViewMovedUp:YES]; } } if ([sender isEqual:txtLeaveAddyLine2]) { //move the main view, so that the keyboard does not hide it. if (self.view.frame.origin.y >= 0) { [self setViewMovedUp:YES]; } } } Am I not using this function correctly?

  • Entity Filter child without include

    - by Lic
    i'm a C# developer and i have a trouble with Entity Framework 5. I have mapped my database with Entity using the default code generation strategy. In particolar there are three classes: menus, submenus and submenuitems. The relationships about three classes are: one menu - to many submenus one submenu - to many submenuitems. All classes have a boolean attribute called "Active". Now, i want to filter all the Menus with the SubMenus active, and the SubMenus with the SubMenuItems active. To get this i've tried this: var tmp = _model.Menus.Where(m => m.Active) .Select => new { Menu = x, SubMenu = x.SubMenus.Where(sb => sb.Active) .Select(y => new { SubMenu = y, SubMenuItem = y.SubMenuItems.Where(sbi => sbi.Active) }) }) .Select(x => x.Menu).ToList(); But didn't work. Someone can help me? Thank you for your help!

  • Simple jQuery syntax help, don't know where I've gone wrong

    - by Jascination
    I'm having trouble with a jQuery code at the moment, I know WHERE the problem lies, but I don't know what the problem is exactly. Probably very basic, but I'm new to this. You can see a (non)working fiddle here: http://www.jsfiddle.net/CvZeQ/ Basically I want to set different .click function based on whatever is selected (I have 5 image maps, each with a different #mapname, and want each to pertain to a different variable (answer1, answer2, answer3...) so as to store the selected 'answer' for each map.) Here is the code I'm using for one of the maps: $(window).load(function(){ //Get cookies when page loaded var useranswers=$.cookie('survery'); useranswers= JSON.parse (useranswers); // do something with previous answers //#shape functions $('#shape area').hover( function(e){ $('#'+ this.alt).addClass('hover'); }, function(e){ $('#'+ this.alt).removeClass('hover'); } ).click( function(e){ $('img.selected-region').removeClass('selected-region'); }, function(e){ $('#'+ this.alt).addClass('selected-region'); }, function(e){ var answer1 = $(this).attr("class"); }); }); I know the problem lies somewhere with the .click function, but I'm not entirely sure what I've done wrong. Any help would be greatly appreciated.

  • [jQuery] What would be the best way to perform a basic CRUD using AJAX

    - by rasouza
    I'm having trouble to make a simple CRUD in my site. I have a table of registries <table> <tbody> <?php foreach ($row as $reg) { ?> <tr <?php if ($reg['value'] < 0) { echo "class='error'"; } ?>> <td><?php echo $reg['creditor'] ?></td> <td><?php echo $reg['debtor'] ?></td> <td><?php echo $reg['reason'] ?></td> <td>R$ <?php echo number_format(abs($reg['value']), 2, ',', ' ')?></td> <td><a **href="<?php echo $this->baseUrl(); ?>/history/delete/id/<?php echo $reg['id']; ?>"** class="delete"><img src="http://192.168.0.102/libraries/css/blueprint/plugins/buttons/icons/cross.png" alt=""/></a></td> </tr> <?php } ?> </tbody> </table> which I would like to perform a simple delete in these rows using AJAX (preferenciably with jQuery). The question is: do I have to create a function in JS and add onmouseclick event in the HTML? is there a more consistent way for doing this, like adding $('.delete').click() directly in the js file? If so, how do I pass the row ID for the ajax function? What I really want is to know how to pass the row ID to $.ajax() jQuery function through a clean! way

  • Trying to edit an entity with data from dropdowns in MVC...

    - by user598352
    Hello! I'm having trouble getting my head around sending multiple models to a view in mvc. My problem is the following. Using EF4 I have a table with attributes organised by category. Couldn't post an image :-( [Have a table called attributes (AttributeTitle, AttributeName, CategoryID) connected to a table called Category (CategoryTitle).] What I want to do is be able to edit an attribute entity and have a dropdown of categories to choose from. I tried to make a custom viewmodel public class AttributeViewModel { public AttributeViewModel() { } public Attribute Attribute { get; set; } public IQueryable<Category> AllCategories { get; set; } } But it just ended up being a mess. <div class="editor-field"> <%: Html.DropDownList("Category", new SelectList((IEnumerable)Model.AllCategories, "CategoryID", "CategoryName")) %> </div> I was getting it back to the controller... [HttpPost] public ActionResult Edit(int AttributeID, FormCollection formcollection) { var _attribute = ProfileDB.GetAttribute(AttributeID); int _selcategory = Convert.ToInt32(formcollection["Category"]); _attribute.CategoryID = (int)_selcategory; try { UpdateModel(_attribute); (<---Error here) ProfileDB.SaveChanges(); return RedirectToAction("Index"); } catch (Exception e) { return View(_attribute); } } I've debugged the code and my _attribute looks correct and _attribute.CategoryID = (int)_selcategory updates the model, but then I get the error. Somewhere here I thought that there should be a cleaner way to do this, and that if I could only send two models to the view instead of having to make a custom viewmodel. To sum it up: I want to edit my attribute and have a dropdown of all of the available categories. Any help much appreciated!

  • ASP.net attachment then refresh page

    - by Russell
    I am working on a c# project using ASP .net. I have a list of reports with a hyperlink for each, which calls the web server, retrieves a PDF and then returns the PDF for the user to save or open: ASPX page: <table> <tr> <td> <a href="#" onclick="SubmitFormToOpenReport();">Open Report 1</a> <td> </tr> ... </table> ASP.Net: context.Response.Clear(); context.Response.AddHeader("content-disposition", "attachment;filename=report.pdf"); context.Response.Charset = ""; context.Response.ContentType = "application/pdf"; context.Response.BinaryWrite(myReport); context.Response.Flush(); This works as expected, however I would like it to also refresh the page with an updated list. I am having trouble as the single request/response is returning the report. Is there a way to refresh the page as well? While there is a correct response, feel free to include answers which details alternative solutions/ideas for doing this.

  • Finding and marking the largest of three values in a two dimensional array

    - by DavidYell
    I am working on a display screen for our office, and I can't seem to think of a good way to find the largest numerical value in a set of data in a two dimensional array. I've looked at using max() and also asort() but they don't seem to cope with a two dimensional array. I'm returning my data through our mysql class, so the rows are returned in a two dimensional array. Array( [0] => Array( [am] => 12, [sales] => 981), [1] => Array( [am] => 43, [sales] => 1012), [2] => Array( [am] => 17, [sales] => 876) ) I need to output a class when foreaching the data in my table for the AM with the highest sales value. Short of comparing them all in if statements. I have tried to get max() on the array, but it returns an array, as it's look within the dimension. When pointing it at a specific dimension it returns the key not the value. I figured that I could asort() the array and pop the top value off, store it in a variable and then compare against that in my foreach() loop, but that seems to have trouble sorting across two dimensions. Lastly, I figured that I could foreach() the values, comparing them against the previous one each time, untill I found the largest. This approach however means storing every value, luckily only three, but then comparing against them all again. Surely there must be a simpler way to achieve this, short of converting it into a single dimension array, then doing an asort() on that?

  • Adding to page control collection from inside a user control

    - by Zarigani
    I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup. The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases." I thought I had found a solution by using... ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) ... which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered." How are you supposed to add controls to the pages control collection from inside a user control?

  • whats a sure shot way to make sure objects appear correctly positioned on stage

    - by dubbeat
    Hi, I've being having a lot of trouble recently getting objects (UIComponents containing movieclips) to appear correctly in the right positions. For example, my current dilema is I have a container that is 3 layers deep. outer layer inner layer display layer This hiearachy was built in CS4 as a movieclip. In the display layer in CS4 I figured out where I want to place 16 different "box" movieclips. I dont want to create these boxes maunually at design time, instead I want to add them at run time. So I know what container I want to add my boxes to. I know what positions they "would" be at in CS4 environment. Whats the best way to add them in the correct locations with code? The "box" I'm trying to add in a movieclip held inside of a UIComponent. Is there a "rule of thumb" to do this type of thing? I'm sure I'm going to encounter this problem again and again and I'd like to just blow the problem out of the water once and for all with the "right way" to do this.

  • How to sort array with undefined elements in IE7 JavaScript

    - by Gene Goykhman
    I am having trouble sorting an array that includes undefined elements (a sparse array) in IE7. This works great in Safari and Firefox of course, and I haven't tried other versions of IE, but here is a simple example. <html> <head> <script type="text/javascript"> function runscript() { var myArray = [{id: 2}, undefined, {id: 0}, {id: 1}, {id: 3}, {id: 4}, {id: 5}]; myArray.sort(function compare(a, b) { return a.id - b.id; }); var output = ''; for (loop in myArray) { output += myArray[loop].id + ' '; } alert(output); } </script> </head> <body onLoad="runscript();"> </body> The alert() at the end inexplicably shows 0 2 3 4 5 1. Removing the undefined element from the array correctly sorts it and the alert shows 0 1 2 3 4 5. Is there a way to work around this in IE7 so that I can reliably sort arrays that include undefined elements? I don't care where the undefined elements end up as long as the defined elements are sorted correctly.

  • Convert Virtual Key Code to unicode string

    - by Joshua Weinberg
    I have some code I've been using to get the current keyboard layout and convert a virtual key code into a string. This works great in most situations, but I'm having trouble with some specific cases. The one that brought this to light is the accent key next to the backspace key on german QWERTZ keyboards. http://en.wikipedia.org/wiki/File:KB_Germany.svg That key generates the VK code I'd expect kVK_ANSI_Equal but when using a QWERTZ keyboard layout I get no description back. Its ending up as a dead key because its supposed to be composed with another key. Is there any way to catch these cases and do the proper conversion? My current code is below. TISInputSourceRef currentKeyboard = TISCopyCurrentKeyboardInputSource(); CFDataRef uchr = (CFDataRef)TISGetInputSourceProperty(currentKeyboard, kTISPropertyUnicodeKeyLayoutData); const UCKeyboardLayout *keyboardLayout = (const UCKeyboardLayout*)CFDataGetBytePtr(uchr); if(keyboardLayout) { UInt32 deadKeyState = 0; UniCharCount maxStringLength = 255; UniCharCount actualStringLength = 0; UniChar unicodeString[maxStringLength]; OSStatus status = UCKeyTranslate(keyboardLayout, keyCode, kUCKeyActionDown, 0, LMGetKbdType(), kUCKeyTranslateNoDeadKeysBit, &deadKeyState, maxStringLength, &actualStringLength, unicodeString); if(actualStringLength > 0 && status == noErr) return [[NSString stringWithCharacters:unicodeString length:(NSInteger)actualStringLength] uppercaseString]; }

  • Benefits of "Don't Fragment" on TCP Packets?

    - by taspeotis
    One of our customers is having trouble submitting data from our application (on their PC) to a server (different geographical location). When sending packets under 1100 bytes everything works fine, but above this we see TCP retransmitting the packet every few seconds and getting no response. The packets we are using for testing are about 1400 bytes (but less than 1472). I can send an ICMP ping to www.google.com that is 1472 bytes and get a response (so it's not their router/first few hops). I found that our application sets the DF flag for these packets, and I believe a router along the way to the server has an MTU less than/equal to 1100 and dropping the packet. This affects 1 client in 5000, but since everybody's routes will be different this is expected. The data is a SOAP envelope and we expect a SOAP response back. I can't justify WHY we do it, the code to do this was written by a previous developer. So... Are there are benefits OR justification to setting the DF flag on TCP packets for application data? I can think of reasons it is needed for network diagnostics applications but not in our situation (we want the data to get to the endpoint, fragmented or not). One of our sysadmins said that it might have something to do with us using SSL, but as far as I know SSL is like a stream and regardless of fragmentation, as long as the stream is rebuilt at the end, there's no problem. If there's no good justification I will be changing the behaviour of our application. Thanks in advance.

  • Array of Arrays - writing to File problem

    - by iFloh
    Hi, and again my array of arrays ... I try to improve my app performance by buffering arrays on file for later reuse. I have an NSMutableArray that contains about 30 NSMutableArrays with NSNumber, NSDate and NSString Objects. I try to write the file using this call: bool result = [myArray writeToFile:[fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]] atomically:NO]; = result = FALSE. The Path method is: + (NSString *) getFullPath:(NSString *)forFileName { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:forFileName]; } and the aDate call returns a shortDateString with ddMMyy. The NSLog NSLog(@"%@", [fileMethods getFullPath:[NSString stringWithFormat:@"iEts%@.arr", [aDate shortDateString]]]); on the path generation returns: /Users/me/Library/Application Support/iPhone Simulator/User/Applications/86729620-EC1D-4C10-A799-0C638BB27933/Documents/iEts010510.arr FURTHER: It must have something to do with the Array of Arrays, since I also write 3 further simple arrays (containing NSStrings) that all succeed. The Array of Arrays gets generated using the addObject method Any ideas what could cause the trouble?

  • Getting Response From Jquery JSON

    - by Howdy_McGee
    I'm having trouble getting a response from my php jquery / json / ajax. I keep combining all these different tutorials together but I still can't seem to pull it all together since no one tutorial follow what I'm trying to do. Right now I'm trying to pass two arrays (since there's no easy way to pass associative arrays) to my jquery ajax function and just alert it out. Here's my code: PHP $names = array('john doe', 'jane doe'); $ids = array('123', '223'); $data['names'] = $names; $data['ids'] = $ids; echo json_encode($data); Jquery function getList(){ $.ajax({ type: "GET", url: 'test.php', data: "", complete: function(data){ var test = jQuery.parseJSON(data); alert(test.names[0]); alert("here"); } }, "json"); } getList(); In my html file all I'm really calling is my javascript file for debugging purposes. I know i'm returning an object but I'm getting an error with null values in my names section, and i'm not sure why. What am I missing? My PHP file returns {"names":["john doe","jane doe"],"ids":["123","223"]} It seems to be just ending here Uncaught TypeError: Cannot read property '0' of undefined so my sub0 is killing me.

  • Global name not defined error in Django/Python trying to set foreignkey

    - by Mark
    Summary: I define a method createPage within a file called PageTree.py that takes a Source model object and a string. The method tries to generate a Page model object. It tries to set the Page model object's foreignkey to refer to the Source model object which was passed in. This throws a NameError exception! I'm trying to represent a website which is structured like a tree. I define the Django models Page and Source, Page representing a node on the tree and Source representing the contents of the page. (You can probably skip over these, this is a basic tree implementation using doubly linked nodes). class Page(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey("self", related_name="children", null=True); firstChild = models.ForeignKey("self", related_name="origin", null=True); nextSibling = models.ForeignKey("self", related_name="prevSibling", null=True); previousSibling = models.ForeignKey("self", related_name="nxtSibling", null=True); source = models.ForeignKey("Source"); class Source(models.Model): #A source that is non dynamic will be refered to as a static source #Dynamic sources contain locations that are names of functions #Static sources contain locations that are places on disk name = models.CharField(primary_key=True, max_length=50) isDynamic = models.BooleanField() location = models.CharField(max_length=100); I've coded a python program called PageTree.py which allows me to request nodes from the database and manipulate the structure of the tree. Here is the trouble making method: def createPage(pageSource, pageName): page = Page() page.source = pageSource page.name = pageName page.save() return page I'm running this program in a shell through manage.py in Windows 7 manage.py shell from mysite.PageManager.models import Page, Source from mysite.PageManager.PageTree import * ... create someSource = Source(), populate the fields, and save it ... createPage(someSource, "test") ... NameError: global name 'source' is not defined When I type in the function definition for createPage into the shell by hand, the call works without error. This is driving me bonkers and help is appreciated.

  • How to understand other people's CSS architectures?

    - by John
    I am reasonably good with CSS. However, when working with someone else's CSS, it's difficult for me to see the "bigger picture" in their architecture (but i have no problem when working with a CSS sheet I wrote myself). For example, I have no problems using Firebug to isolate and fix cross browser compatibility issues, or fixing a floating issue, or changing the height on a particular element. But if I'm asked to do something drastic such as, "I want the right sidebars of pages A, B, C and D to have a red border. I want the right side bars of pages E, F and G to have a blue border if and only if the user mouses over", then it takes me time a long time to map out all the CSS inheritance rules to see the "bigger picture". For some reason, I don't encounter the same difficulty with backend code. After a quick debriefing of how a feature works, and a quick inspection of the controller and model code, I will feel comfortable with the architecture. I will think, "it's reasonable to assume that there will be an Employee class that inherits from the Person Class that's used by a Department controller". If I discover inconvenient details that aren't consistent with overall architectural style, I am confident that I can hammer things back in place. With someone else's CSS work, it's much harder for me to see the "relationships" between different classes, and when and how the classes are used. When there are many inheritance rules, I feel overwhelmed. I'm having trouble articulating my question and issues... All I want to know is, why is it so much harder for me to see the bigger picture in someone else's CSS architecture than compared to someone else's business logic layer? **Does it have any thing to do with CSS being a relatively new technology, and there aren't many popular design patterns?

  • dynamic inheritance without touching classes

    - by Jasper
    I feel like the answer to this question is really simple, but I really am having trouble finding it. So here goes: Suppose you have the following classes: class Base; class Child : public Base; class Displayer { public: Displayer(Base* element); Displayer(Child* element); } Additionally, I have a Base* object which might point to either an instance of the class Base or an instance of the class Child. Now I want to create a Displayer based on the element pointed to by object, however, I want to pick the right version of the constructor. As I currently have it, this would accomplish just that (I am being a bit fuzzy with my C++ here, but I think this the clearest way) object->createDisplayer(); virtual void Base::createDisplayer() { new Displayer(this); } virtual void Child::createDisplayer() { new Displayer(this); } This works, however, there is a problem with this: Base and Child are part of the application system, while Displayer is part of the GUI system. I want to build the GUI system independently of the Application system, so that it is easy to replace the GUI. This means that Base and Child should not know about Displayer. However, I do not know how I can achieve this without letting the Application classes know about the GUI. Am I missing something very obvious or am I trying something that is not possible?

  • How to have an excel addin read rows from a worksheet until no more data?

    - by user169867
    I've started writing a Com addin for Excel 2003 using C#. I'm looking for a code example showing how to read in cell data from the active worksheet. I've seen that you can write code like this: Excel.Range firstCell = ws.get_Range("A1", Type.Missing); Excel.Range lastCell = ws.get_Range("A10", Type.Missing); Excel.Range worksheetCells = ws.get_Range(firstCell, lastCell); to grab a range of cells. What I could use help with is how to read the cell data when you don't know how many rows of data there are. I may be able to determine the starting row that the data will be begin at, but there will be an unkown number of rows of data to read. Could someone provide me w/ an example of how to read rows from the worksheet until you come across a row of empty cells? Also does anyone know how to grab the range of cells the user has selected? Any help would be greatly appreciated. This seems like a powerful dev tool, but I'm having trouble finding detailed documentation to help me learn it :)

  • Jquery passing an HTML element into a function

    - by christian
    I have an HTML form where I am going to copy values from a series of input fields to some spans/headings as the user populates the input fields. I am able to get this working using the following code: $('#source').keyup(function(){ if($("#source").val().length == 0){ $("#destinationTitle").text('Sample Title'); }else{ $("#destinationTitle").text($("#source").val()); } }); In the above scenario the html is something like: Sample Title Basically, as the users fills out the source box, the text of the is changed to the value of the source input. If nothing is input in, or the user deletes the values typed into the box some default text is placed in the instead. Pretty straightforward. However, since I need to make this work for many different fields, it makes sense to turn this into a generic function and then bind that function to each 's onkeyup() event. But I am having some trouble with this. My implementation: function doStuff(source,target,defaultValue) { if($(source).val().length == 0){ $(target).text(defaultValue); }else{ $(target).text($(source).val()); } } which is called as follows: $('#source').keyup(function() { doStuff(this, '"#destinationTitle"', 'SampleTitle'); }); What I can't figure out is how to pass the second parameter, the name of the destination html element into the function. I have no problem passing in the element I'm binding to via "this", but can't figure out the destination element syntax. Any help would be appreciated - many thanks!

    I'm attempting to mine twitter data in R, and am having trouble getting started. I created a twitter account, an app in twitter developers, changed the settings to read, write, and access, created my access token, and followed instructions to the letter in registering it: My code: > library(twitteR) > download.file(url="http://curl.haxx.se/ca/cacert.pem", + destfile="cacert.pem") > requestURL <- "https://api.twitter.com/oauth/request_token" > accessURL <- "https://api.twitter.com/oauth/access_token" > authURL <- "https://api.twitter.com/oauth/authorize" > consumerKey <-"my key" #took this part out for privacy's sake > consumerSecret <- "my secret" #this too > twitCred <- OAuthFactory$new(consumerKey=consumerKey, consumerSecret = consumerSecret, requestURL = requestURL, accessURL = accessURL, authURL = authURL) > twitCred$handshake(cainfo="cacert.pem") To enable the connection, please direct your web browser to: https://api.twitter.com/oauth/authorize?oauth_token=zxgHXJkYAB3wQ2IVAeyJjeyid7WK6EGPfouGmlx1c When complete, record the PIN given to you and provide it here: 0010819 > registerTwitterOAuth(twitCred) [1] TRUE > save(list="twitCred", file="twitteR_credentials") And yet, this: > s <- searchTwitter('#United', cainfo="cacert.pem") [1] "Unauthorized" Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) : Error: Unauthorized I'm about to have a temper tantrum. I'd be extremely grateful if someone could explain to me what is going wrong, or, better yet, how to fix it. Thank you.

  • A data structure based on the R-Tree: creating new child nodes when a node is full, but what if I ha

    - by Tom
    I realize my title is not very clear, but I am having trouble thinking of a better one. If anyone wants to correct it, please do. I'm developing a data structure for my 2 dimensional game with an infinite universe. The data structure is based on a simple (!) node/leaf system, like the R-Tree. This is the basic concept: you set howmany childs you want a node (a container) to have maximum. If you want to add a leaf, but the node the leaf should be in is full, then it will create a new set of nodes within this node and move all current leafs to their new (more exact) node. This way, very populated areas will have a lot more subdivisions than a very big but rarely visited area. This works for normal objects. The only problem arises when I have more than maxChildsPerNode objects with the exact same X,Y location: because the node is full, it will create more exact subnodes, but the old leafs will all be put in the exact same node again because they have the exact same position -- resulting in an infinite loop of creating more nodes and more nodes. So, what should I do when I want to add more leafs than maxChildsPerNode with the exact same position to my tree? PS. if I failed to explain my problem, please tell me, so I can try to improve the explanation.
