• Reservation Solution for RealEstate integrating with Joomla

  - by Pennf0lio

  Hi, My client needs a Property (Just Land NO Houses) Reservation solution for their existing website (It runs in Joomla). I need some advice/Tips on what approach should I use. I'm looking for an Opensource solution that I can customize to my need. The Scenario: A buyer reserves a lot, A form appears gathers his details after that he/she pays for the reservation. FrontEnd: I need a form builder extension in Joomla that I could build custom form in gathering information (name, email, contact info, address...) from the buyer or the person who is reserving it. After I gather the info I need another extension that will handle the payment for reserving it. This is kinda shopping cart type approach, you see a product and the buy it. But would just need extra details. Backend: I can see all the details of the buyer from their name to the time they paid for a reservation. Thanks! P.S. I'm open to all Ideas. I'm not sure of this approach. Please let me know If you have some good Ideas or example.

• Has anyone setup tomcat to run virtual hosts using mod_jk

  - by Adam

  I work in OSX primarily with mostly PHP. Normally I work locally using MAMP and virtual hosts setup in my httpd.conf so that I can point a browser to http://some-project and have as many projects as I need setup. We have a project coming up where we need to serve JSP pages and I would like to set up my local apache server to serve only JSP files to Tomcat and everything else to MAMP using the same virtual hosts setup in: ~/applications/MAMP/conf/apache/httpd.conf So far I have: Successfully installed Tomcat Placed mod_jd.so in ~/applications/MAMP/Library/modules/mod_jk.so Added the module by placing: LoadModule jk_module modules/mod_jk.so in ~/applications/MAMP/conf/apache/httpd.conf Created /Library/Tomcat/Home/conf/jk/workers.properties and added the following lines: workers.tomcat_home=/Library/Tomcat workers.java_home=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home ps=/ worker.list=ajp12, ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp12.type=ajp13 worker.ajp13.mount=/*.jsp added the following lines: JkWorkersFile /Library/Tomcat/Home/conf/workers.properties JkLogFile /Library/Tomcat/Home/logs/mod_jk.log JkLogLevel debug to ~/applications/MAMP/conf/apache/httpd.conf I cannot start my MAMP however when these last two lines are present in my httpd.conf. Does anyone work like this? Any tips? Any clear ideas of what I'm doing wrong?

• Best practice to test a web application, regarding domain name and integration with external service

  - by ycseattle

  I have run into these problems several times and was never able to find a comfortable solution. Let's say my website has the domain name MyDomain.com. When I run the tests on the test machine (a continuous integration server), I will modify the HOSTS file on this machine so the MyDomain.com is mapped to this local machine instead of the real production server. This doesn't work very well for many situations. For example, my application will create subdomain names user1.MyDomain.com dynamically but this is difficult to keep the testing flexible. Another problem is my web application will interact with Amazon S3, and sometimes other service like Amazon Simple Message Queue. I am only comfortable to include these interaction in my tests but I am never happy with my solution for mixing testing and production on Amazon services. Could somebody offer some tips on these issues? I would like to make my testing framework clean and flexible. I am sure this is a common question for all web applications and there must be a mature way to deal with these. Thanks!

• Reading strings and integers from .txt file and printing output as strings only

  - by screename71

  Hello, I'm new to C++, and I'm trying to write a short C++ program that reads lines of text from a file, with each line containing one integer key and one alphanumeric string value (no embedded whitespace). The number of lines is not known in advance, (i.e., keep reading lines until end of file is reached). The program needs to use the 'std::map' data structure to store integers and strings read from input (and to associate integers with strings). The program then needs to output string values (but not integer values) to standard output, 1 per line, sorted by integer key values (smallest to largest). So, for example, suppose I have a text file called "data.txt" which contains the following three lines: 10 dog -50 horse 0 cat -12 zebra 14 walrus The output should then be: horse zebra cat dog walrus I've pasted below the progress I've made so far on my C++ program: #include <fstream> #include <iostream> #include <map> using namespace std; using std::map; int main () { string name; signed int value; ifstream myfile ("data.txt"); while (! myfile.eof() ) { getline(myfile,name,'\n'); myfile >> value >> name; cout << name << endl; } return 0; myfile.close(); } Unfortunately, this produces the following incorrect output: horse cat zebra walrus If anyone has any tips, hints, suggestions, etc. on changes and revisions I need to make to the program to get it to work as needed, can you please let me know? Thanks!

• Trying to update a google visualization using jquery

  - by Mark in A2

  I'm relatively inexperienced, so please bear with me. I'm developing a simple dashboard using the Google visualization API. I'm developing in vb.net. I have the Annotated Timeline, the Intensity Map, and a set of tables on my apsx. What I am trying to do is update the Intensity Map and tables based on the date range the user selects using the Annotated Timeline tool. I was hoping to update only these visualizations without doing a full page load. Apparently, a great way to do this is to separate the visualizations into self-contained aspx pages and use jQuery to "load" them into a div. I say apparently, as this is not working. When I try to update an aspx containing a Google visualization using jQuery, I get the message "Loading data from www.google.com..." in the browser and it just runs continuously and never returns. I ran this by an experienced developer and he was stumped, but thought must be a conflict between the google API and jQuery. Any tips, advice, alternative solutions are greatly appreciated! Thanks, Mark in Ann Arbor

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

  - by Matt

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

• Handling user interface in a multi-threaded application (or being forced to have a UI-only main thre

  - by Patrick

  In my application, I have a 'logging' window, which shows all the logging, warnings, errors of the application. Last year my application was still single-threaded so this worked [quite] good. Now I am introducing multithreading. I quickly noticed that it's not a good idea to update the logging window from different threads. Reading some articles on keeping the UI in the main thread, I made a communication buffer, in which the other threads are adding their logging messages, and from which the main thread takes the messages and shows them in the logging window (this is done in the message loop). Now, in a part of my application, the memory usage increases dramatically, because the separate threads are generating lots of logging messages, and the main thread cannot empty the communication buffer quickly enough. After the while the memory decreases again (if the other threads have finished their work and the main thread gradually empties the communication buffer). I solved this problem by having a maximum size on the communication buffer, but then I run into a problem in the following situation: the main thread has to perform a complex action the main thread takes some parts of the action and let's separate threads execute this while the seperate threads are executing their logic, the main thread processes the results from the other threads and continues with its work if the other threads are finished Problem is that in this situation, if the other threads perform logging, there is no UI-message loop, and so the communication buffer is filled, but not emptied. I see two solutions in solving this problem: require the main thread to do regular polling of the communication buffer only performing user interface logic in the main thread (no other logic) I think the second solution seems the best, but this may not that easy to introduce in a big application (in my case it performs mathematical simulations). Are there any other solutions or tips? Or is one of the two proposed the best, easiest, most-pragmatic solution? Thanks, Patrick

• LINQ to Entity: using Contains in the "select" portion throws unexpected error

  - by Chu

  I've got a LINQ query going against an Entity Framework object. Here's a summary of the query: //a list of my allies List<int> allianceMembers = new List<int>() { 1,5,10 }; //query for fleets in my area, including any allies (and mark them as such) var fleets = from af in FleetSource select new Fleet { fleetID = af.fleetID, fleetName = af.fleetName, isAllied = (allianceMembers.Contains(af.userID) ? true : false) }; Basically, what I'm doing is getting a set of fleets. The allianceMembers list contains INTs of all users who are allied with me. I want to set isAllied = true if the fleet's owner is part of that list, and false otherwise. When I do this, I am seeing an exception: "LINQ to Entities does not recognize the method 'Boolean Contains(Int32)' method" I can understand getting this error if I had used the contains in the where portion of the query, but why would I get it in the select? By this point I would assume the query would have executed and returned the results. This little ditty of code does nothing to constrain my data at all. Any tips on how else I can accomplish what I need to with setting the isAllied flag? Thanks

• Why is Firefox so bloated? [closed]

  - by bvandrunen

  First off I am a developer who loves firebug and other development tools (and no Chrome firebug lite does not cut it) and am just utterly frustrated when I have been using Firefox lately. It is at the point where I use Chrome for absolutely everything but web development but am still frustrated that I had to switch where half a year ago or more Firefox was fine. Why can't there be a Firefox lite? One that is free from all the bloat that has been plaguing Firefox recently. Also if there are any tools or tips that I can free up my Firefox that would be great. I am using the newest version + as few add-ons as possible. EDIT: I have tried Chrome Developer Tools and I do like them...but I can't get passed the firebug lite extension of Chrome. Some of the developer tools are great but sometimes they just have too much information. I extensively use Firebug/myphp admin. Both of these work much much better in Firefox then Chrome. But I hate that it takes me so much longer to load and use everything.

• Problems with overriding OnPaint and grabbing mouse events in C# UserControl containing other controls

  - by MoreThanChaos

  I've made a control which contains few other controls like PictureBox, Label and TextBox. But I'm having two problems: 1. I tried to paint some things on top of my control and when I'm overriding OnPaint, it results that things I try to draw are under controls that my control contains. Areas on which I would like to draw intersect with controls in ways that are not easy to predict. I mean that it includes something drawn on controls inside as well as on base of control. Is there a simple way to draw something on top of all contents of my control? Setting ForeColor to Transparent isn't a solution that would help me much. 2. I have a problem with grabbing mouse click events when I place my control on a form and add click event handling. It only works when I click on an area not occupied by controls inside. I would like the whole control to react to clicks and other actions like it was one consistent control. How can I redirect/handle these clicks to make them work the way I want? Thanks in advance for any tips

• SEO google keyword position tools?

  - by Peterl86

  Hi guys, I want to check our google postions for several keywords every day and make a note in a spreadseet. At the moment, we have a student doing it but it's a rubbish job and it doesn't seem fair on them! Are there any tools available to automate this process? I have tried rankchecker by seobook.com, but although that should be exactly what im looking for when i set scheduled tasks in that, it doesnt work. Any tips would be appreciated, thanks! peter EDIT: Liam has suggested a Python script to do this, which unfortunately isnt something I'm very familiar with! If anyone knows of a good tutorial or something to help us with this, that would be brilliant. Update: Found a php script at seoscript.net which looks like a step in the right direction. But I cant get it to work! I get this error. Anyone more knowledgabe than me know how to fix that? I have PEAR installed. thanks again, Peter

• Ruby shortest/most efficient way to write rnd hex

  - by Whirlwin

  Hi. What I have is a method used to generate random hex values. E.g 666 or FF7 However, I don't think it is efficient at all.. What I want is to make it more efficient which perhaps will make my code shorter as well, but I don't know how. That is why I need tips or hints Here is my code so far: def random_values random_values = Array.new letters = ['A','B','C','D','E','F'] for i in 1..15 if i <= 9 random_values << i else random_values << letters[i-10] end end return random_values.shuffle[0].to_s + random_values.shuffle[0].to_s + random_values.shuffle[0].to_s end As you probably see, I do not generate random numbers. I just shuffle the array containing the values I want, meaning all the numbers in the array are unique, which is not needed, but was the easiest solution for me when I wrote the code. I am most concerned about the return line.. If only it was possible to write like: return 3.times { random_values.shuffle[0] } or return random_values.shuffle[0].to_s *3 Thanks in advance!

• How to get the size of a binary tree ?

  - by Andrei Ciobanu

  I have a very simple binary tree structure, something like: struct nmbintree_s { unsigned int size; int (*cmp)(const void *e1, const void *e2); void (*destructor)(void *data); nmbintree_node *root; }; struct nmbintree_node_s { void *data; struct nmbintree_node_s *right; struct nmbintree_node_s *left; }; Sometimes i need to extract a 'tree' from another and i need to get the size to the 'extracted tree' in order to update the size of the initial 'tree' . I was thinking on two approaches: 1) Using a recursive function, something like: unsigned int nmbintree_size(struct nmbintree_node* node) { if (node==NULL) { return(0); } return( nmbintree_size(node->left) + nmbintree_size(node->right) + 1 ); } 2) A preorder / inorder / postorder traversal done in an iterative way (using stack / queue) + counting the nodes. What approach do you think is more 'memory failure proof' / performant ? Any other suggestions / tips ? NOTE: I am probably going to use this implementation in the future for small projects of mine. So I don't want to unexpectedly fail :).

  Hey guys, I have been trying every tips you already gave to other mates that where having the same issue but I just can't manage to do it ... My app isn't even special, it is a basic app with a tab bar and nav bar ... I currently got something like this in the controller I push (that i want to be fullscreen) : - (void)viewDidLoad { [super viewDidLoad]; self.view.autoresizingMask = 0; self.view.superview.autoresizingMask = 0; [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackTranslucent]; //[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; [self.navigationController.navigationBar setBarStyle:UIBarStyleBlackTranslucent]; CGRect test = CGRectMake(0.0,0.0,320,44); //[self.navigationController.navigationBar setFrame:test]; //[self setWantsFullScreenLayout:YES]; [self.view.superview setBounds:CGRectMake(0,-20.0,320,480)]; //[self.view setBounds:[[UIScreen mainScreen] bounds]]; [self.view setBounds:CGRectMake(0,-20.0,320,480)]; //CGRect rect4 = CGRectMake(0.0,0.0,320.0,500.0); //[self.view setFrame:rect4]; [self.view setBackgroundColor:[UIColor redColor]]; } As you can see I tried a lot of stuff :D but my red background isn't going under my status bar ...

• Maven3 Issues with building a multi-module enterprise project

  - by Sujit K

  I just migrated from Maven2 to Maven3 and I'm able to build each module individually or all the modules in one shot by calling mvn clean install. However, in Maven2, since we have multi-module enterprise project, we build multiple ear's and each ear is built as its own module with its own child pom. To build an individual ear with its dependents, the below command works fine in Maven2 but not in Maven3. Let me explain the issue in Maven3 a bit later. mvn -pl ear_module -rf first_dependent_module -am clean install In Maven2 when the reactor lists the build order, I see first_dependent_module second_dependent_module ear_module End of the day I have my ear module also part of the reactor which is how it should be. The reason we call -rf is we don't want to delete the target folder at the main ${project.basedir} (so not to delete the output created in target from building the other ear modules). With Maven3, however, this is all I see when the reactor lists the build order: first_dependent_module second_dependent_module Maven3 totally ignores the argument (ear_module) set to -pl flag to be also built after its dependents have been. Not sure what I'm missing here. Any help/tips would be greatly appreciated. P.S: The build I'm making is similar to the one below.... Build specific module in multi-module project Thanks, SK

• git commit best practices

  - by Ivan Z. Siu

  I am using git to manage a C++ project. When I am working on the projects, I find it hard to organize the changes into commits when changing things that are related to many places. For example, I may change a class interface in a .h file, which will affect the corresponding .cpp file, and also other files using it. I am not sure whether it is reasonable to put all the stuff into one big commit. Intuitively, I think the commits should be modular, each one of them corresponds to a functional update/change, so that the collaborators could pick things accordingly. But seems that sometimes it is inevitable to include lots of files and changes to make a functional change actually work. Searching did not yield me any good suggestion or tips. Hence I wonder if anyone could give me some best practices when doing commits. Thanks! PS. I've been using git for a while and I know how to interactively add/rebase/split/amend/... What I am asking is the PHILOSOPHY part.

• Property on business objects - getting and setting

  - by Mike

  Hi, I am using LINQ to SQL for the DataAccess layer. I have similar business objects to what is in the data access layer. I have got the dataprovider getting the message #23. On instantiation of the message, in the message constructor, it gets the MessageType and makes a new instance of MessageType class and fills in the MessageType information from the database. Therefore; I want this to get the Name of the MessageType of the Message. user.Messages[23].MessageType.Name I also want an administrator to set the MessageType user.Messages[23].MessageType = MessageTypes.LoadType(3); but I don't want the user to publicly set the MessageType.Name. But when I make a new MessageType instance, the access modifier for the Name property is public because I want to set that from an external class (my data access layer). I could change this to property to internal, so that my class can access it like a public variable, and not allow my other application access to modify it. This still doesn't feel right as it seems like a public property. Are public access modifiers in this situation bad? Any tips or suggestions would be appreciated. Thanks.

• How to get at specific HTML elements of a document using C# and Hide them/Show them etc.

  - by LaserBeak

  Basically I want to load a HTML document and using controls such as multiple check boxes which will be programmed to hide, delete or show HTML elements with certain ID's. So I am thinking I would have to set an inline CSS property for visibility to: false on the ones I want to hide or delete them altogether when necessary. I need this so I don't have to edit my Ebay HTML templates in dreamweaver all the time, where I usually have to scroll around messy code and manually delete or add tags and their respective content. Whereas I just want to create one master template in dreamweaver which has all the variations that my products have, since they are all of the same genre with slight changes here and there and I just need to enable and disable the visibility of these variants as required and copy + paste the final html. I haven's used Windows Forms before, but tried doing this in WebForms which I do know a bit. I am able to get the result that I want by wrapping any HTML elements in a <asp:PlaceHolder></asp:PlaceHolder> and just setting that place holders visibility to false after the associated checkbox is checked and a postback occurs, finally I add a checkbox/button control that removes all the checkboxes, including itself etc for final html. But this method seems just like too much pain in the ass as I have to add the placeholder tags around everything that I need control over as ordinary html elements do not run at server, also webforms injects a bunch of Javascript and ViewState data so I don't have clean HTML which I can just copy after viewing the page source. Any tips/code that you can suggest to achieve the desired effect with the least changes required to existing HTML documents? Ideally I would want to load the HTML document in, have a live design preview of it and underneath have a bunch of well labelled checkboxes programmed to hide, delete or show elements with certain ID's. Thanks...

• jQuery re-checking check boxes

  - by Jacob

  Hi, I having problems with re-checking some checkboxes after and ajax call updates a table. I have a table of what the project calls 'shares'. I want to: 1) check for and save any checked shares to an array 2) Do my ajax call to update the table of shares 3) Re-check any there we checked before the ajax update. My code is not working and I can't see why? Any tips, help or advise much appreciated. // Array to hold our checked share ids var savedShareIDs = new Array(); // Add checked share ids into array $("input:checkbox[name=share_ids]:checked").each(function() { savedShareIDs.push($(this).val()); }); // Do ajax update Dajaxice.pagination_shares('Dajax.process',{'id':1, 'page':1}) // Re-check any that were checked before ajax update $("input:checkbox[name=share_ids]").each(function() { if ( $.inArray( $(this).val(), savedShareIDs) > -1 ) { $(this).attr('checked',true) } }); The problem is the checkboxes are not checking. I'm pretty sure the loop is working and the inArray check works. Just not checking the checkboxes. Can anyone see where I'm going wrong? Thanks.

• Including/Organzing HTML in large javascript project

  - by Bill Zimmerman

  Hi, I've a got a fairly large web app, with several mini applets on each page. These applets are almost always identical jquery apps. I am looking for advice on how I should organize/include smaller parts of these jquery apps within my larger project. For example, each app has several independent tabs. If possible, I would like to store each of the tabs as a seperate .html file because this makes development easier. My requirements are: 1) All of the html 'tabs' are loaded on the clients end when the page loads. I would like to avoid any delays by dynamically requesting the tab html. 2) If possible, I would like to minimize the raw data sent. For example, it would be preferable to send each tab 1 time, instead of sending each tab 10 times if there are ten applets on that page. Questions: 1) What are my options for 'including' the HTML files / javascript code 2) Any tips for keeping my development simple in this situation? Surely there has to be a better way than just editing one massive html file when working with large pages.

• What kind of library to use for display of graphical objects and right click context menus

  - by Gopal

  Hi all, Goal: To develop a web based NMS interface which displays a network topology (e.g., switches, routers, links, endhosts). Each node should be 'movable' (draggable to an appropriate place manually or their best location computed algorithmically). I should be able to zoom into the network graph (say if there are many clusters of nodes and I want to concentrate on a particular cluster of nodes). I should be able to right-click any node or link and get a context menu (e.g., 'show routing table', 'show interfaces', 'show bandwidth utilization graph' etc.). The data for this network topology will be fetched by making calls to an apache based webserver where the backend scripts in python will fetch the appropriate data and send it via JSON to the web client. Question: I am assuming that some sort of javascript library/framework will be most appropriate for this - jQuery, Dojo, Moo etc. [I've never used any of these before]. Which of these would be most recommended for this sort of thing. Which would be easiest to learn (say in a months time). Thanks for any tips.

• Saving multiple items per single database cell...

  - by eugeneK

  Hi, i have a countries list. Each user can check multiple countries. Once saved, this "user country list" will be used to get whether other users fit into countries certain user chose. Question is what would be the most efficient approach to this problem... I have one, one to save user selection as delimited list like Canada,USA,France ... in single varchar(max) field but problem with it would be that once user from Germany enters page i perform this check on. To search for Germany i would be needed to get all items and un-delimit each field to check against value or to use sql 'like' which again is pretty damn slow.. If you have better solution or some tips i would be glad to hear. Just to make sure, many users will have their own selections of countries from which and only they want to have users to land on their page. While millions of users will reach those pages. So the faster approach will be the better. technology, MSSQL and ASP.NET thanks

• JQuery: how to store records id for data from ajax query in dynamicly created html elements

  - by grapkulec

  Probably question title is rather cryptic but I will try to explain myself here so please bare with me :) Let's assume this configuration: server-side is PHP application responding for requests with data (list of items, single item details, etc.) in json format client-side is JQuery application sending ajax request to that PHP app and creating html content corresponding with received data So, for example: client requests "list of all animals with names staring with 'A'", gets the json response from server, and for every "animal" creates some html gizmo like div with animal description or something like that. It doesn't really matter what html element it will be but it has to point exactly to specific record by "containing" id of that record. And here is my dilemma: is it good solution to use "id" property for that? So it would be like: <div id="10" class="animal"> <p> This is animal of very mysterious kind... </p> </div> <div id="11" class="animal"> <p> And this one is very common to our country... </p> </div> where id="10" is of course indication that this is representation of record with id = 10. Or maybe I should store this record id in some custom made tag like <record_id>10</record_id> and leave an "id" strictly for what it was meant to be (css selector)? I need that record id for further stuff like updating database with some user input or deleting some of "animals" or creating new ones or anything that will be needed. All manipulations will be done with JQuery and ajax requests and responses will be visualized also with dynamic creation of html interface. I'm sure that somebody had to deal with that kind of stuff before so I would be grateful for some tips on that topic.

Here is a code snippet: SqlConnection conn2 = new SqlConnection(connString); SqlCommand cmd = conn2.CreateCommand(); cmd.CommandText = "dbo.AppendDataCT"; cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = conn2; SqlParameter p1, p2, p3; foreach (string s in dt.Rows[1].ItemArray) { DataRow dr = dt.Rows[1]; // second row p1 = cmd.Parameters.AddWithValue((string)dic[0], (string)dr[0]); p1.SqlDbType = SqlDbType.VarChar; p2 = cmd.Parameters.AddWithValue((string)dic[1], (string)dr[1]); p2.SqlDbType = SqlDbType.VarChar; p3 = cmd.Parameters.AddWithValue((string)dic[2], (string)dr[2]); p3.SqlDbType = SqlDbType.VarChar; } but this is giving me compiler error: The best overloaded method match for 'System.Collections.Generic.Dictionary<string,string>.this[string]' has some invalid arguments I just want to access each value from "dic" and load into these SQL parameters. How do I do this? Do I have to enter the key? The keys are named "col1", "col2", etc., so not the most user-friendly. Any other tips? Thanks!
