  • ApplicationDelegate is not doing its own job here ! Can anyone help me??

    - by ahmet732
    (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MaSystemGuiAppDelegate *appDelegate = (MaSystemGuiAppDelegate *)[[UIApplication sharedApplication] delegate]; appDelegate.deneme = [tableData objectAtIndex:indexPath.row] ; NSLog(@"my row", appDelegate.deneme); // THIS IS NOT PRINTING NSLog(@"my row = %@", [tableData objectAtIndex:indexPath.row]); //THIS IS PRINTING THE VALUE ON CONSOLE NSInteger row = [indexPath row]; if(self.searchDetailViewController == nil){ SearchDetailViewController *asearchDetail = [[SearchDetailViewController alloc] initWithNibName:@"SearchDetailView" bundle:nil]; self.searchDetailViewController = asearchDetail; [asearchDetail release]; } searchDetailViewController.title = [NSString stringWithFormat:@"%@", [searchArray objectAtIndex:row]]; MaSystemGuiAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.searchNavController pushViewController:searchDetailViewController animated:YES]; } "deneme" is a NMUtableArray is identified in MaSystemGuiAppDelegate.h (I identified it as a variable and put its property there) and I wrote "deneme= [[NSMutableArray alloc]init]; in applicationDidFinishLaunching method in MaSystemGuiAppDelegate.m. In the code above, [tableData objectAtIndex:indexPath.row] is retrieving the one of the value touched on tableview. When I put that value in deneme (as u noticed in the code) it is printing nothing. What am i missing? (I imported MaSystemGuiAppDelegate.h)

  • Why won't my Setup Project Perform my Custom Registration Process

    - by Jordan S
    I am trying to write an Setup Project/Installer for a class library driver that I wrote in C# using Visual Studio 2008. The driver project has a section of code that looks like this... [ComRegisterFunction] public static void RegisterASCOM(Type t) { Trace.WriteLine("Registration Started."); DoRegistration(true); } In the driver project Properties - "Assembly Information" I have set checked the box that says Make COM-Visible = true. I added a Setup Project to the solution in VS, added the output dll from the driver project so that it installs on the target machine and set the Register property of the dll to "vsdraCOM". So, my understanding is that when the installer runs it SHOULD execute the methods of the dll that are marked with [COMRegisterFunction]. Using SysInternals Debug View I can monitor when the above code snippet is hit by watching for the "Registration started" text to show up in the window. When I build the solution, I can see the text show up so I know the driver is registering properly. The problem is that when I run the installer, I don't think it is doing the registration bit. I see nothing show up in Debug View. And if i try to access my driver via another application I get an error saying it "Cannot create ActiveX object". Why does the registration not occur during the install process? The driver does register for COM but it does NOT call my custom registration method. Does anyone have and suggestions of what I could be missing? Is there another way I can debug this? (I can provide more code if anyone want's to take a look!!)

  • Facebook-ios-sdk with embedded UIWebView

    - by Benchtop Creative
    I'm working with the new facebook-ios-sdk and have successfully integrated the api into my native app. I am able to authenticate a user and properly setup permissions using a popup dialog with the ios-sdk classes. For a portion of my app I need to use the facebook connection within a UIWebView, using javascript and html to process data within the webview. Given that the user is already logged in and authenticated via the above routine, I would have assumed that the UIWebView would share those credentials, or that there would at least be some way to pass or assign the credentials to the webview. Unfortunately, I found this earlier post which seems to suggest that this scheme doesn't quite work (iOS - being logged-in in a webView after logging in with the SDK). Has anyone else encountered this and/or found a work around? This seems like it would be a fairly straightforward use case given that I'm not trying to launch mobile safari or something like that - it's all within the same native app. It just seems like there must be some sort of easy trick or setting that I'm missing. Maybe somehow setting cookies in the new UIWebView? or something like this?

  • What does this model error says in asp.net mvc?

    - by Pandiya Chendur
    My Html action link takes me to a view where i can see the details.. For Ex:http://localhost:1985/Materials/Details/4 But it shows error, The model item passed into the dictionary is of type 'System.Data.Linq.DataQuery`1[CrMVC.Models.ConstructionRepository+Materials]' but this dictionary requires a model item of type 'CrMVC.Models.ConstructionRepository+Materials'. And my model is... public IQueryable<Materials> GetMaterial(int id) { return from m in db.Materials join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id where m.Mat_id == id select new Materials() { Id = Convert.ToInt64(m.Mat_id), Mat_Name = m.Mat_Name, Mes_Name = Mt.Name, }; } public class Materials { private Int64 id; public string mat_Name; public string mes_Name; public Int64 Id { get { return id; } set { id = value; } } public string Mat_Name { get { return mat_Name; } set { mat_Name = value; } } public string Mes_Name { get { return mes_Name; } set { mes_Name = value; } } } } and my controller method... public ActionResult Details(int id) { var material = consRepository.GetMaterial(id).AsQueryable(); return View("Details", material); } Any suggestion what am i missing here?

  • Correct answer will not output

    - by rEgonicS
    I made a program that returns the sum of all primes under 2 million. I really have no idea what's going on with this one, I get 142891895587 as my answer when the correct answer is 142913828922. It seems like its missing a few primes in there. I'm pretty sure the getPrime function works as it is supposed to. I used it a couple times before and worked correctly than. The code is as follows: vector<int> getPrimes(int number); int main() { unsigned long int sum = 0; vector<int> primes = getPrimes(2000000); for(int i = 0; i < primes.size(); i++) { sum += primes[i]; } cout << sum; return 0; } vector<int> getPrimes(int number) { vector<bool> sieve(number+1,false); vector<int> primes; sieve[0] = true; sieve[1] = true; for(int i = 2; i <= number; i++) { if(sieve[i]==false) { primes.push_back(i); unsigned long int temp = i*i; while(temp <= number) { sieve[temp] = true; temp = temp + i; } } } return primes; }

  • Can I get an XPathNodeIterator directly from an XPath?

    - by Val
    I hope I'm just missing something obvious. I have a number of repeating nodes in an XML document: <root> <parent> <child/> <child/> </parent> </root> I need to examine the contents of each of the <child> elements in turn, so I need an XPathNodeIterator containing the nodeset of all the <child> nodes. If I have an XPath that would select the child nodes, e.g. /root/parent/child, is there any way to feed that directly to a new XPathNodeIterator? Everything I see in the docs and examples indicates I have to first get an XPathNavigator to the <parent>, then Select the child nodes, like: XPathNavigator nav = datasource.CreateNavigator().SelectSingleNode( "/root/parent" ); XPathNodeIterator it = nav.Select( "./child" ); foreach ( child in it ) { /* do something */ } I was hoping to skip the XPathNavigator, and intialize the XPathNodeIterator with XPath to the child nodes directly, something like: XpathNodeIterator it = new XpathNodeIterator("/root/parent/child"); foreach ( child in it ) { /* do something */ } Possible? The benefit is not only saving a line of code, but I can use a single XPath expression, rather than splitting the path to the <child> nodes in two, first to get the parent element, then to select its children.

  • C# & SQL Server Authentication

    - by Peter
    Hello, I'm currently developing a C# app with an SQL Server DB back-end. I'm approaching the point of deployment and hitting a problem. The applicaiton will be deployed within an active directory network. As far as SQL authentication goes, I understand that I have 2 options - Windows Authenticaiton or Server Authenticaiton. If I use Server Authentication, I'm concerned that the username and password for the account will be stored in plain text in the app.config file, and therefore leave the database vulnerable. Using Windows Authenticaiton will avoid this issue, however it would mean giving every member of staff within our organisation read/write access to the database in order to run the app correctly. Whilst this is ok, it also means that they can easily connect to the database themselves via other means and directly alter the data outside of the app. I'm guessing there is someting really obvious I'm missing here, but I've been googling all evening to no avail. Any advice/guidance would be much appreciated! Peter Addition - my project is Windows Form based not ASP.NET - is encrypting the app.config file still the right answer? If it is, does anyone have any examples that are not ASP.NET based?

  • Why would an OS X bundle take about 30 seconds to open?

    - by Aftermathew
    Hi, We wrote a simple OS X executable in objective c. It opens and runs very quickly when called. We then put that executable into a .app bundle. When calling "open" from the command line on that bundle, or double clicking the app from the finder the "open" call can take upwards of 30 seconds to return. This is especially confusing because "open" clearly starts the executable right away (I can see it running in the process list right away, and have other indications that it's doing work), but when done from the command line, the "open" command takes a long time to return, and when done from the Finder the icon will bounce for a very long time before acting normal. I know the executable itself still opens very quickly because calling "open" on the executable inside my bundle returns very quickly, however calling it on the .app runs the code right away but takes 30 seconds or so to return. Has anyone run into this before? Do you have any suggestions for what could cause something like this? I've not been able to see anything funny in the bundle structure or the plist, but maybe I'm missing something. Thanks,

  • directory resource does not create directory

    - by Dan Tenenbaum
    I have a Vagrantfile that provisions a VM by running a chef recipe. The first resource in the chef recipe is: directory "/downloads" do owner "root" group "root" mode "0755" action :create end # check that it worked: raise "/downloads doesn't exist!" unless File.exists? "/downloads" When I run this at work, it works fine. When I run it at home, it fails, the exception is raised when I check to see if /downloads exists. I'm not sure why this is happening. I would expect it to behave identically, since the underlying Vagrant box is the same both at work and at home. I am a chef newb so perhaps there is something I am not understanding about the order in which the resources are run within my recipe? I would expect them to run in sequential order... I also tried putting a notifies call inside the directory block, where I call another execute block :immediately. That works, but inside the second execute block I test to see whether /downloads has been created and it hasn't. Clearly I'm missing something very basic.

  • How to programmatically create a node in Drupal 8?

    - by chapka
    I'm designing a new module in Drupal 8. It's a long-term project that won't be going public for a few months at least, so I'm using it as a way to figure out what's new. In this module, I want to be able to programmatically create nodes. In Drupal 7, I would do this by creating the object, then calling "node_submit" and "node_save". These functions no longer exist in Drupal 8. Instead, according to the documentation, "Modules and scripts may programmatically submit nodes using the usual form API pattern." I'm at a loss. What does this mean? I've used Form API to create forms in Drupal 7, but I don't get what the docs are saying here. What I'm looking to do is programmatically create at least one and possibly multiple new nodes, based on information not taken directly from a user-presented form. I need to be able to: 1) Specify the content type 2) Specify the URL path 3) Set any other necessary variables that would previously have been handled by the now-obsolete node_object_prepare() 4) Commit the new node object I would prefer to be able to do this in an independent, highly abstracted function not tied to a specific block or form. So what am I missing?

  • RegEx: difference between "(?:...) and normal parentheses

    - by N0thing
    >>> re.findall(r"(?:do|re|mi)+", "mimi") ['mimi'] >>> re.findall(r"(do|re|mi)+", "mimi") ['mi'] According to my understanding of the definitions, it should produce the same answer. The only difference between (...) and (?:...) should be whether or not we can use back-references later. Am I missing something? (...) Matches whatever regular expression is inside the parentheses, and indicates the start and end of a group; the contents of a group can be retrieved after a match has been performed, and can be matched later in the string with the \number special sequence, described below. To match the literals '(' or ')', use ( or ), or enclose them inside a character class: [(] [)]. (?:...) A non-capturing version of regular parentheses. Matches whatever regular expression is inside the parentheses, but the substring matched by the group cannot be retrieved after performing a match or referenced later in the pattern.

  • Building an 'Activation Key' Generator in JAVA

    - by jax
    I want to develop a Key generator for my phone applications. Currently I am using an external service to do the job but I am a little concerned that the service might go offline one day hence I will be in a bit of a pickle. How authentication works now. Public key stored on the phone. When the user requests a key the 'phone ID' is sent to the "Key Generation Service" and the encrypted key key is returned and stored inside a license file. On the phone I can check if the key is for the current phone by using a method getPhoneId() which I can check with the the current phone and grant or not grant access to features. I like this and it works well, however, I want to create my own "Key Generation Service" from my own website. Requirements: Public and Private Key Encryption:(Bouncy Castle) Written in JAVA Must support getApplicationId() (so that many applications can use the same key generator) and getPhoneId() (to get the phone id out of the encrypted license file) I want to be able to send the ApplicationId and PhoneId to the service for license key generation. Can someone give me some pointers on how to accomplish this? I have dabbled around with some java encryption but am definitely no expert and can't find anything that will help me. A list of the Java classes I would need to instantiate would be helpful.

  • Lock-Free Data Structures in C++ Compare and Swap Routine

    - by slf
    In this paper: Lock-Free Data Structures (pdf) the following "Compare and Swap" fundamental is shown: template <class T> bool CAS(T* addr, T exp, T val) { if (*addr == exp) { *addr = val; return true; } return false; } And then says The entire procedure is atomic But how is that so? Is it not possible that some other actor could change the value of addr between the if and the assignment? In which case, assuming all code is using this CAS fundamental, it would be found the next time something "expected" it to be a certain way, and it wasn't. However, that doesn't change the fact that it could happen, in which case, is it still atomic? What about the other actor returning true, even when it's changes were overwritten by this actor? If that can't possibly happen, then why? I want to believe the author, so what am I missing here? I am thinking it must be obvious. My apologies in advance if this seems trivial.

  • Memory management of objects returned by methods (iOS / Objective-C)

    - by iOSNewb
    I am learning Objective-C and iOS programming through the terrific iTunesU course posted by Stanford (http://www.stanford.edu/class/cs193p/cgi-bin/drupal/) Assignment 2 is to create a calculator with variable buttons. The chain of commands (e.g. 3+x-y) is stored in a NSMutableArray as "anExpression", and then we sub in random values for x and y based on an NSDictionary to get a solution. This part of the assignment is tripping me up: The final two [methods] “convert” anExpression to/from a property list: + (id)propertyListForExpression:(id)anExpression; + (id)expressionForPropertyList:(id)propertyList; You’ll remember from lecture that a property list is just any combination of NSArray, NSDictionary, NSString, NSNumber, etc., so why do we even need this method since anExpression is already a property list? (Since the expressions we build are NSMutableArrays that contain only NSString and NSNumber objects, they are, indeed, already property lists.) Well, because the caller of our API has no idea that anExpression is a property list. That’s an internal implementation detail we have chosen not to expose to callers. Even so, you may think, the implementation of these two methods is easy because anExpression is already a property list so we can just return the argument right back, right? Well, yes and no. The memory management on this one is a bit tricky. We’ll leave it up to you to figure out. Give it your best shot. Obviously, I am missing something with respect to memory management because I don't see why I can't just return the passed arguments right back. Thanks in advance for any answers!

  • Creating Binary Block from struct

    - by MOnsDaR
    I hope the title is describing the problem, i'll change it if anyone has a better idea. I'm storing information in a struct like this: struct AnyStruct { AnyStruct : testInt(20), testDouble(100.01), testBool1(true), testBool2(false), testBool3(true), testChar('x') {} int testInt; double testDouble; bool testBool1; bool testBool2; bool testBool3; char testChar; std::vector<char> getBinaryBlock() { //how to build that? } } The struct should be sent via network in a binary byte-buffer with the following structure: Bit 00- 31: testInt Bit 32- 61: testDouble most significant portion Bit 62- 93: testDouble least significant portion Bit 94: testBool1 Bit 95: testBool2 Bit 96: testBool3 Bit 97-104: testChar According to this definition the resulting std::vector should have a size of 13 bytes (char == byte) My question now is how I can form such a packet out of the different datatypes I've got. I've already read through a lot of pages and found datatypes like std::bitset or boost::dynamic_bitset, but neither seems to solve my problem. I think it is easy to see, that the above code is just an example, the original standard is far more complex and contains more different datatypes. Solving the above example should solve my problems with the complex structures too i think. One last point: The problem should be solved just by using standard, portable language-features of C++ like STL or Boost (

  • How to get acts on taggable working

    - by Schipperius
    I am new to ruby on rails (and programming) and this is probably a really stupid question. I am using Rails 3.2 and trying to use acts_as_taggable_on to generate tags on articles and to have those tags show on article index and show pages as a clickable links. I have tags clickable on both the article show and index pages, but the links just go back to the index page and don't sort according to the tag name. I have scoured the Internet and pieced together the code below from various sources, but I am clearly missing something. Any help is greatly appreciated, as I have exhausted my seemingly limited knowledge! Thanks. Here is what I have: class ArticlesController < ApplicationController def tagged @articles = Article.all(:order => 'created_at DESC') @tags = Article.tag_counts_on(:tags) @tagged_articles = Article.tagged_with(params[:tags]) respond_to do |format| format.html # index.html.erb format.json { render :json => @articles } end end def index @article = Article.new @articles = Article.paginate :page => params[:page], :per_page => 3 @tags = Article.tag_counts_on(:tags) respond_to do |format| format.html # index.html.erb format.json { render json: @articles } end end module ArticlesHelper include ActsAsTaggableOn::TagsHelper end class Article < ActiveRecord::Base acts_as_ordered_taggable acts_as_ordered_taggable_on :tags, :location, :about attr_accessible :tag_list scope :by_join_date, order("created_at DESC") end article/index.html.erb <% tag_cloud(@tags, %w(tag1 tag2 tag3 tag4)) do |tag| %> <%= link_to tag.name, articles_path(:id => tag.name) %> <% end %> article/show.html.erb <%= raw @article.tags.map { |tag| link_to tag.name, articles_path(:tag_id => tag) }.join(" | ") %>

  • folder structure in a mercurial repo?

    - by ajsie
    I have just switched from svn to mercurial and have read some tutorials about it. I've still got some confusions that i hope you could help me to sort out. I wonder if I have understood the folder structure in a mercurial repo right. In a svn repo I usually have these folders: svn: branches (branches/chat, branches/new_login etc) tags (version1.0, version2.0 etc) sandbox trunk Should a branch actually be another clone of the original/central repo in mercurial? it seemed like that when I read the manual. And a tag is just a named identifier, but you should clone the original/central repo whenever you want to create a tag? How about the sandbox? should that be another clone too? So basically you just have in a repo all the folders/files that you would have in the trunk folder? mercurial: central repo: projects folders/files (not in any parentfolder) tag repo: cloned from central repo at a given moment for release (version1.0, version2.0 etc) branch repo: cloned from central repo for adding features (chat, new_login etc) sandbox repo: experimental repo (could be pushed to central repo, or just deleted) is this correct?

  • Mapping relationships from multiple databases in NHibernate

    - by mannish
    I have a multi-database application configured with NHibernate. The entities that correspond to tables from each database are in their own separate assemblies (an assembly per database if you will). I have a need/desire to relate an entity from one database to an entity of another database. Everything up to this point works as I want it to (the application handles multiple session factories, etc.). The relationship I want is many-to-one, but in reality my application only cares about one side of the relationship (for reasons that aren't relevant). The relevant entities are Project and PMProject, where a Project HAS A PMProject. When I map the many-to-one, I get the following error: NHibernate.MappingException: An association from the table PROJECTS refers to an unmapped class: SDMS.PPRM.PMProject The Project mapping itself reads (ignore the funky column naming; it's an Oracle db): <many-to-one name="PMProject" class="SDMS.PPRM.PMProject" column="PM_PROJECT_ID" cascade="none" /> In the class attribute, I'm referencing the appropriate assembly, but I get that error which seems to tell me it simply can't find the mapping file for PMProject. But that file exists (it's set as embedded resource), the session factory instantiation works without fail; so I'm at a loss on how to tell the Project mapping how/where to look for the appropriate mapping. Is there something I'm missing? A better way to go about this? Thanks in advance.

  • How Best to Replace PL/SQL with C#?

    - by Mike
    Hi, I write a lot of one-off Oracle SQL queries/reports (in Toad), and sometimes they can get complex, involving lots of unions, joins, and subqueries, and/or requiring dynamic SQL, and/or procedural logic. PL/SQL is custom made for handling these situations, but as a language it does not compare to C#, and even if it did, it's tooling does not, and if even that did, forcing yet another language on the team is something to be avoided whenever possible. Experience has shown me that using SQL for the set based processing, coupled with C# for the procedural processing, is a powerful combination indeed, and far more readable, maintainable and enhanceable than PL/SQL. So, we end up with a number of small C# programs which typically would construct a SQL query string piece by piece and/or run several queries and process them as needed. This kind of code could easily be a disaster, but a good developer can make this work out quite well, and end up with very readable code. So, I don't think it's a bad way to code for smaller DB focused projects. My main question is, how best to create and package all these little C# programs that run ad hoc queries and reports against the database? Right now I create little report objects in a DLL, developed and tested with NUnit, but then I continue to use NUnit as the GUI to select and run them. NUnit just happens to provide a nice GUI for this kind of thing, even after testing has been completed. I'm also interested in suggestions for reporting apps generally. I feel like there is a missing piece or product. The perfect tool would allow writing and running C# inside of Toad, or SQL inside of Visual Studio, along with simple reporting facilities. All ideas will be appreciated, but let's make the assumption that PL/SQL is not the solution.

(Q2) How can I make sure that I'll only store the same type(int,varchar,text) that I setted,declared in the database. For example: age(int), but if someone types "abc" in the input it will be stored in my database as the value 0 . How can I forbid this, and only save the age when it's just int and all the other fields(like name, email) are filled ?. And if is still possible warn the user that he is typing something wrong, don't need to say where. Sorry for any mistake in English and Thanks for the attention.

  • Need opinions on LaTeX and ever upgrading

    - by yCalleecharan
    Hi, I've been using LaTeX since 2005 with the TeXLive distribution and I've been upgrading as each new TeXLive distribution comes out. In the recent years I noticed an increase in new packages, updated packages and in one instance a new package bearing a different name replacing an old one by the same package author. A LaTeX document which relies heavily on packages and which has been produced a few years back may start to get some warnings and error messages on present-day LaTeX compilation. The primary reason I switched to LaTeX is because of its reliability and robustness to create big documents easily, not to mention the adorable typographic quality. With LaTeX one doesn't have to worry about how to open a docx in an old program supporting only doc for instance. Now, when there are so much continual changes in the packages in a LaTeX distribution, I tend to wonder when will this madness end. Not that having enhanced and new features are bad in packages, but not all updated packages are backward compatible. Eventually one would like to be able to compile a LaTeX file in 10 years time that he/she is working on at present and not get any compilation warnings/error messages due to some unpredictable behavior of updated packages or due to a package that has been cast-off from a LaTeX distribution. If I understand correctly CTAN do keep a database with all packages from different versions. I would like to know how you LaTeX users handle this issue. Thanks a lot...

  • Cannont Update control in WPF custom control

    I have created a custom control which holds a button in it. The button is styled, so as to hold a grid with two rows, an image in the first and a TextBlock in the second. I have written an Event Handler for the custom control. When the mouse enters the path of the object the MouseEnter event fires, where I try to change the TextBlock's FontSize and Foreground color, however the control does not update. In contrast, I have tried to modify an regular TextBlock's(not part a custom control and controltemplate) properties, and they update correctly, on the fly. What am I missing here?? Here is the code for the event handler: private void ThemeButton_MouseEnter(object sender, MouseEventArgs e) { InitializeProperties(); TextElement.FontSize = 16; TextElement.Text = "new text"; TextElement.Foreground = Brushes.Red; TextBlock element = MainWindow.FindChild<TextBlock>(MainWindow.StartWindow, "textField"); element.Text = "new text for regular textblock"; element.Foreground = Brushes.Red; } InitializeProperties is a methid that initializes TextElement(typeof TextBlock) and ImageElement(typeof Image) properties. They are not null. The properties are just regular .NET properties.

  • How can I get git to work with a remote server?

    - by Adrienne
    I am the CM person for a small company that just started using Git. We have two Git repositories currently hosted on a Windows box that is our all-purpose Windows server. But, we just set up a dedicated server for our CM software on an Ubuntu Linux server named "Callisto". So I created a test Git repository on Callisto. I gave its directory all of the proper permissions recursively. I had the sysadmin create a login for me on Callisto, and I created a key to use for logging in via SSH. I set up my key to use a passphrase; I don't know if that could be contributing to my problems? Anyway, I know my SSH login works because I tested it through puTTY. But, even after hours of trials and head scratching, I can't get my Windows Git bash (mSysGit) to talk to Callisto for the purposes of pushing or pulling Callisto's git repository files. I keep getting "Fatal error. The remote end hung up unexpectedly." And I've even gotten the error that Git doesn't recognize the test repository on Callisto as a git repository. I read online that the "Fatal error...hung up unexpectedly" is usually a problem with the server connection or permissions. So what am I missing or overlooking here? And why doesn't a pull using the git:// protocol work, since that only uses read-only access? Group and public permissions for the git repository's directory on Callisto are set to read and execute, but not write. If anyone could help, I would be so grateful. Thank you.
