  • Why use Entity Framework over Linq2SQL if...

    - by Refracted Paladin
    To be clear, I am not asking for a side by side comparision which has already been asked Ad Nauseum here on SO. I am also Not asking if Linq2Sql is dead as I don't care. What I am asking is this.... I am building internal apps only for a non-profit organization. I am the only developer on staff. We ALWAYS use SQL Server as our Database backend. I design and build the Databases as well. I have used L2S successfully a couple of times already. Taking all this into consideration can someone offer me a compelling reason that I should use EF instead of L2S? I was at Code Camp this weekend and after an hour long demonstration on EF, all of which I could have done in L2S, I asked this same question. The speakers answer was, "L2S is dead..." Very well then! NOT! (see here) I understand EF is what MS WANTS us to use in the future(see here) and that it offers many more customization options. What I can't figure out is if any of that should, or does, matter for me in this environment. One particular issue we have here is that I inherited the Core App which was built on 4 different SQL Data bases. L2S has great difficulty with this but when I asked the aforementioned speaker if EF would help me in this regard he said "No!"

  • Framework/service for hosting and managing files

    - by Peteris Caune
    Hi, in a webapp I'm building there is a planned side feature of supporting product illustrations and manuals (so pictures and PDFs), possibly arranged in galleries. As I'd rather not implement from scratch all of the uploading, managing and serving of this content, I'm looking for existing solutions which I could integrate. For example, I'm considering Flickr--users of webapp specify their Flickr username and then use some naming convention to link objects in my webapp with pictures uploaded in their Flickr account. Very little code to write from my side, maybe just some API calls that proxy Flickr APIs, since Flickr would handle picture uploading, organizing them in sets, storing them in cloud and serving them in various sizes etc. One drawback here is that either all of the the pictures are public or I have to deal with interactive Flickr authorization. Also not sure if Flickr would be happy being used in such manner. What other online services or libraries/frameworks I should look at? My webapp is written in Python/Pylons, so Python libraries would be preferred. I'm already using some of Amazon infrastructure, so frontends to Amazon S3 would be cool. For online services, RESTful API would be nice.

  • Why do I get Error#2036 in flash AS3 and how to solve this?

    - by sydas
    I'm currently building an application in flash in relation to RSS/XML feeds for a project. I'm stuck at the moment because I keep getting this error: Error opening URL 'http://distilleryimage6.instagram.com/.jpg' Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed. I know my string picURL is not functioning properly, but am I missing something that makes it not functional? This is my code: package { import flash.display.*; import flash.events.*; import flash.net.*; public class instagramFeed extends MovieClip { //link to #rit xml loader public var ritFileRequest = new URLRequest("http://instagram.com/tags/rit/feed/recent.rss"); public var ritXmlLoader = new URLLoader(); //link to #rochester xml loader // same as above public variables public function instagramFeed() { // constructor code trace("About to load..."); //Loads #rit hashtag xml data. ritXmlLoader.load(ritFileRequest); ritXmlLoader.addEventListener(Event.COMPLETE, displayRITInfo); } //focuses on data with #rit hashtag public function displayRITInfo(e:Event):void{ var ritInstagramData:XML = new XML(ritXmlLoader.data); var ritInfoList:XMLList = ritInstagramData.elements().item; trace(ritInfoList); //load the image var ritPic:String = ritInfoList.*::condition.@code; var picURL:String = "http://distilleryimage6.instagram.com/" + ritPic + ".jpg"; trace(picURL); //show the image on the stage! var ritImageRequest:URLRequest = new URLRequest(picURL); var ritImageLoader:Loader = new Loader(); ritImageLoader.load(ritImageRequest); addChild(ritImageLoader); ritImageLoader.x=200; ritImageLoader.y=100; ritImageLoader.scaleX = 3; ritImageLoader.scaleY = 3; } } }

  • Concatenate an each loop inside another

    - by Lothar
    I want to to concatenate the results of a jquery each loop inside of another but am not getting the results I expect. $.each(data, function () { counter++; var i = 0; var singlebar; var that = this; tableRow = '<tr>' + '<td>' + this.foo + '</td>' + $.each(this.bar, function(){ singlebar = '<td>' + that.bar[i].baz + '</td>'; tableRow + singlebar; }); '</tr>'; return tableRow; }); The portion inside the nested each does not get added to the string that is returned. I can console.log(singlebar) and get the expected results in the console but I cannot concatenate those results inside the primary each loop. I have also tried: $.each(this.bar, function(){ tableRow += '<td>' + that.bar[i].baz + '</td>'; }); Which also does not add the desired content. How do I iterate over this nested data and add it in the midst of the table that the primary each statement is building?

  • Risky Business with LINQ to SQL and OR Designer?

    - by Toadmyster
    I have two tables with a one to many relationship in SQL 2008. The first table (BBD) PK | BBDataID | int       | Floor_Qty | tinyint       | Construct_Year | char(4)       | etc, etc describes the data common to all buildings and the second (BBDCerts) PK | BBDCertsID | int       | BBDataID | int       | Certification_Type | varchar(20)       | etc, etc is a collection of certifications for a particular building. Thus, the primary key in BBD (BBDataID) is mapped to the corresponding field in BBDCerts via an FK relationship, but BBDCertsID is the second table's primary key and BBDataID is not because it will not be unique. My problem is that I want to be able to use the OR generated data context to get at the list of certs when I access a particular record in the BBD table. For instance: Dim vals = (From q in db.BBD Where q.BBDataID = x Select q.Floor_Qty, q.Construct_Year, q.BBDCerts).SingleOrDefault and later be able to access a particular certification like this: vals.BBDCerts.Certification_Type.First Now, the automatic associations created when the SQL tables are dropped on the design surface don't generate the EntityRef associations that are needed to access the other table using the dot notation. So, I have to use the OR designer to make the BBDCerts BBDataID a primary key (this doesn't affect the actual database), and then manually change the association properties to the appropriate OneToMany settings. There might be a better way to approach this solution but my question is, is the way I've done it safe? I've done a barrage of tests and the correct cert is referenced or updated every time. Frankly, the whole thing makes me nervous.

  • How to insert result of mysql_real_escape_string() into oracle database?

    - by Prat
    For inserting special characters in data like (,')etc., I am using musql_real_escape_string() function & it's working fine. Now I want to use same variable while inserting values in Oracle. $str = 'N.G.Palace\'s Building', 'xyzcity', '12345678','India','100001',12 Here $str is result of mysql_real_escape_string(). so it escapes special character. Now my code for oracle is like this-: $qry ="INSERT INTO Ora_table(ship_to_street, ship_to_city,ship_to_country, ship_to_telephone, order_id, record_no) VALUES(".$str); So my doubt is Oracle is not accepting values return by mysql_real_escape_string i.e. Palace\'s (like this as this mysql function attach \ before 'single quote)? So can anybody tell me ho9w can I use that variable $str to insert data into Oracle? Also I tried like this also-: "q"."'"."c".$str."c"."'" can we use this for multiple values like in my case...though still I am unable to inser data in oracle? plz help.

  • Database (MySQL) structuring: pros and cons of multiple tables

    - by Gideon
    I am collecting data and storing it MySQL, for: 75 variables 55 countries Each year I have, at this stage since I am building this tool created a single table, of variables / countries (storing 1 year worth of data). Next year (and for several years after that) a new set of data will be input for each country. There are therefore 3 variables in controlling data returned to a user reviewing all collected data. The general form of any query would be: Show me these specifics variables, for these specific countries, for these specific years. (Show me average age and weight, for USA and Canada, for 2012 and 2009, for example) My question is, it seems that I have two options for arranging this data: -Multiple tables where I create a table of country / variable for each year data is collected - Single table and simply add a column (field) for the year that data relates to. As far as I can tell I could make these database calls with either sructure, but is one more powerful / efficient / quicker, and why? Thanks for your consideration. It's a PDO / PHP interface if that is relevent.

  • Parallel programming, are we not learning from history again?

    - by mezmo
    I started programming because I was a hardware guy that got bored, I thought the problems being solved in the software side of things were much more interesting than those in hardware. At that time, most of the electrical buses I dealt with were serial, some moving data as fast as 1.5 megabit!! ;) Over the years these evolved into parallel buses in order to speed communication up, after all, transferring 8/16/32/64, whatever bits at a time incredibly speeds up the transfer. Well, our ability to create and detect state changes got faster and faster, to the point where we could push data so fast that interference between parallel traces or cable wires made cleaning the signal too expensive to continue, and we still got reasonable performance from serial interfaces, heck some graphics interfaces are even happening over USB for a while now. I think I'm seeing a like trend in software now, our processors were getting faster and faster, so we got good at building "serial" software. Now we've hit a speed bump in raw processor speed, so we're adding cores, or "traces" to the mix, and spending a lot of time and effort on learning how to properly use those. But I'm also seeing what I feel are advances in things like optical switching and even quantum computing that could take us far more quickly that I was expecting back to the point where "serial programming" again makes the most sense. What are your thoughts?

  • Best method to search heriarachal data

    - by WDuffy
    I'm looking at building a facility which allows querying for data with hierarchical filtering. I have a few ideas how I'm going to go about it but was wondering if there are any recommendations or suggestions that might be more efficient. As an example imagine that a user is searching for a job. The job areas would be as follows. 1: Scotland 2: --- West Central 3: ------ Glasgow 4: ------ Etc 5: --- North East 6: ------ Ayrshire 7: ------ Etc A user can search specific (ie Glasgow) or in a larger area (ie Scotland). The two approaches I am considering are 1: keep a note of children in the database for each record (ie cat 1 would have 2, 3, 4 in its children field) and query against that record with a SELECT * FROM Jobs WHERE Category IN Areas.childrenField. 2: Use a recursive function to find all results who have a relation to the selected area The problems I see from both are 1: holding this data in the db will mean having to keep track of all changes to structure 2: Recursion is slow and inefficent Any ideas, suggestion or recommendations on the best approach? I'm using C# ASP.NET with MSSQL 2005 DB.

  • Memory not being returned after function python call

    - by Dan
    I've got a function which does a parse of a sentence by building up a big chart. For some reason, Python holds on to whatever memory was allocated during that function call. That is, I do best = translate(sentence, grammar) and somehow my memory goes up and stays up. Here is the function: from string import join from heapq import nsmallest, heappush def translate(f, g): words = f.split() chart = {} for col in range(len(words)): for row in reversed(range(0,col+1)): # get rules for this subspan rules = g[join(words[row:col+1], ' ')] # ensure there's at least one rule on the diagonal if not rules and row==col: rules=[(0.0, join(words[row:col+1]))] # pick up rules below & to the left for k in range(row,col): if (row,k) and (k+1,col) in chart: for (w1, e1) in chart[row, k]: for (w2, e2) in chart[k+1,col]: heappush(rules, (w1+w2, e1+' '+e2)) # add all rules to chart chart[row,col] = nsmallest(MAX_TRANSLATIONS, rules) (w, best) = chart[0, len(words)-1][0] return best EDIT: Using Python 2.7 on OS X. The grammar g is just a dictionary from strings to heaps, e.g.: g['et'] [(1.05, 'and'), (6.92, ', and'), (9.95, 'and ,'), (11.17, 'and to')] EDIT: If you want to run the code, try the sentence "Cela est difficile" with the following grammar: >>> g['cela'] [(8.28, 'this'), (11.21, 'it'), (11.57, 'that'), (15.26, 'this ,')] >>> g['est'] [(2.69, 'is'), (10.21, 'is ,'), (11.15, 'has'), (11.28, ', is')] >>> g['difficile'] [(2.01, 'difficult'), (10.08, 'hard'), (10.19, 'difficult ,'), (10.57, 'a difficult')]

  • Best way and problems when using ajax tabs with an MVC PHP project

    - by Jonathan
    Hi, I'm building an IMDB.com like website using PHP/jQuery and a MVC approach (no OOP). I have an index.php base controller to 'rule them all' :), a controllers folder with all the controllers, a models folder and a view folder. In some pages of the website I have tabbed navigation, when the visitor clicks on one of those tabs to get more information, jQuery gets that data using the $.post or $.get method and shows it on the tab container, obviously without refreshing the page. The problem is that those pages loaded by ajax are also generated using controllers, models, and views, and the things are getting a bit complicated for someone like me ( = 'no experience'). To dynamically get the data I some times need to include a model twice, include an include in an include in an include, send information multiple times, connect with the database again, and all sort of things like that and I'm sure there is a better and prettier way to do this. I'm searching for the best approach and common methods for this. I have no experience working with a big project like this. This is a personal project so I have full control and every answer is welcome. Thanks!!!

  • Which DVCS would work best on Windows for my scenario?

    - by PoorLuzer
    At work I use ClearCase and SourceSafe, but have found some time to do some time to code for myself enroute thanks to a disposable laptop. However, I wish I had a lightweight VCS on my system using which I would be able to make changes to my code during the commute and then push/grab them from my Linux systems. I use git on my home system, but I can't really get it working on Windows. I don't want all that cygwin hack. If it does not run natively on Windows, it just won't do. What have you guys tried on your Windows system? Something that YOU use. The big player at the moment seems to be Mercurial? What would be best for a one (or maybe two) man team? I just need to maintain : Versioned copies of source code. Checking in and out should be as less obtrusive as possible. I am looking forward to a multiple Undo kind of feature (like that in an EMacs buffer) but persistent. I really like the way git keeps track of lines moving between files in a source code set I should be able to move part(s)/sub tree(s) of the source tree (each sub tree implies a module/plugin to my the main software I am building) to an archival system either completly or partially and restore them back from the archive as and when required and the system should track any changes to this tree as well. I actually want to experiment with my code as much as possible without me manually keeping track of what I modified and what I need to undo once I try out some idea, so that I am back to where I want to continue from. Notes : A similar topic came up a year ago : http://stackoverflow.com/questions/4670/dvcs-choices-whats-good-for-windows I hope things have changed, and I really want people to share their own, real life experiences. Not something they recommend without using it or they think will work.

  • How can I prevent the scaling of a UIWebview's content after reorientation?

    - by frankhermes
    I'm building an iOS 5/6 app that has a UIWebView. It loads some HTML that I have embedded in my app. Now when I rotate my device, the WebView changes its size (as I want it to fill the entire width of the screen). And then it gets weird: some content gets scaled up and some content doesn't get scaled up. See this image with some example text in it: As you can see, the header (H6) stays the same, while the paragraph gets scaled up. Does anybody have an idea how to prevent this? I want the html to look the same in landscape as it does in portrait mode. I've tried setting the viewport scaling to 1: <meta name="viewport" content="initial-scale=1.0,max-scale=1.0"> but that doesn't help. The body's font-size style is set to 14px, but changing that to 14pt or a percentage also made no difference. Setting the width of the body to 100% also didn't help. Strangely, removing the line break (<br/>) that's in the text fixes it but I need line breaks to be in there so that's no solution. The only thing that does work is reloading the UIWebView's content after an orientation change, but that doesn't prevent it from looking wrong during rotation, and it resets any scrolling that the user may have done. Any ideas?

  • Javascript Application Book

    - by Jormundir
    Can anyone recommend a good book on Javascript module/application development. I'm a Software Engineer, so I don't need all the intro to programming stuff. What I'm really looking for is: How do you bundle the html/css/javascript together so that you can make one include that will load the whole application. I.e.: <div id="myapplication"></div> ... ... <script src="myapplication.js"> Design patterns are always welcome. I've already read Javascript the good parts, and online guides, but it's hard to find a comprehensive guide/tutorial for specifically this. There's a lot of good "this is a javascript application" and "this is a scalable framework", but I haven't had any luck with "This is how you build a javascript application, including the html and css, and this is how you deliver it nicely". I'm building a small application to start, so I'm not interested in scalability and large-scale development practices, just a nice and comprehensive guide to get me off the ground.

  • Why is joining two vectors simply not working?

    - by Jim
    I have two vectors of MyObj structs. MyObj is defined as follows: struct MyObj { float x, y; unsigned int data[8]; unsigned int tmp[1]; MyObj(const MyObj &m) { x = m.x; y = m.y; tmp[0] = 0; for (int i = 0; i < 8; ++i) { data[i] = m.data[i]; } } }; I then have two vectors... vector<MyObj> v1; vector<MyObj> v2; // both get data eventually. v1.insert(v1.end(), v2.begin(), v2.end()); v2 has 3535004 elements in my experiment. v1 is similarly sized. I've also tried building a new vector and just using .push_back to build it from both vectors. Essentially, when I try to merge the two vectors I just get an error from visual studio saying "Debug error! R6010, abort() has been called". Very non-useful... So my question is: what could be causing this error, and how can I solve it? Thank you

  • Optimizing landing pages

    - by Oleg Shaldybin
    In my current project (Rails 2.3) we have a collection of 1.2 million keywords, and each of them is associated with a landing page, which is effectively a search results page for a given keywords. Each of those pages is pretty complicated, so it can take a long time to generate (up to 2 seconds with a moderate load, even longer during traffic spikes, with current hardware). The problem is that 99.9% of visits to those pages are new visits (via search engines), so it doesn't help a lot to cache it on the first visit: it will still be slow for that visit, and the next visit could be in several weeks. I'd really like to make those pages faster, but I don't have too many ideas on how to do it. A couple of things that come to mind: build a cache for all keywords beforehand (with a very long TTL, a month or so). However, building and maintaing this cache can be a real pain, and the search results on the page might be outdated, or even no longer accessible; given the volatile nature of this data, don't try to cache anything at all, and just try to scale out to keep up with traffic. I'd really appreciate any feedback on this problem.

  • Can I automate a loop query based on category with the page's title?

    - by jordaninternets
    To explain further, I need to get a page to display posts from a specific category. I want to automate this process so I don't have to make a template for each category. How would I do that? (keep in mind the person I'm building this is for has no coding experience.) The only way I could think off from the top of my head is to use the title or slug. So if the category is named the same thing as the slug, could I filter by category using the slug? Maybe this isn't the best way... what should I do? This is what I came up with, but it doesn't work, I'm sure due to improper use on may part, but I've been pouring over the WP codex and Google with no avail to tell me my problem. <?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; $args= array( 'orderby' => 'date', 'order' => 'ASC', 'paged' => $paged, 'category_name' => echo the_title('\'','\'',) ); query_posts($args); ?>

  • jQuery menu animation

    - by bomortensen
    Hi Stackoverflow, I'm building a website where I'm using jQuery to animate a horizontal tabbed menu. What I want to achieve can be seen here: / link removed / If you hover/mouseover the "Link 1" tab, you'll see that a white div is expanding. Each of the tab menu items are a styled li-tag. What I want to do is, that when you hover/mouseover i.e. the "Link 2" tab, the white div contracts and then expands again with content related to "Link 2" instead of "Link 1". Also, the "Link 1" tab should be expanded by default (i.e. when you just entered the site) Does any of you jQuery ninjas out there know how to do this? What I currently have is this: <script type="text/javascript"> $(document).ready(function(){ var $div = $('#divtest'); var height = $div.height(); $div.hide().css({ height : 0 }); $('#forside').hover(function () { if ($div.is(':visible')) { $div.animate({ height: 0 }, { duration: 200, complete: function () { $div.hide(); } }); } else { $div.show().animate({ height : height }, { duration: 200 }); } return false; }); }); </script> Do I need to have 4 different div's which expands/contracts for every mouseover? If i'm not being clear about what my problem is, please say so and I'll try to elaborate :) Thanks in advance!

  • jQuery .val() Selector Confusion

    - by Matt Dawdy
    I've kind of written myself into a corner, and was hoping there was an "easy" way out. I'm trying to loop through a series of things on my page, and build a key:value pair. Here is my structure: <div class="divMapTab" id="divMapTab34"> <div class="divFieldMap"> <select class="selSrc" id="selTargetnamex"><options....></select> </div> </div> <div class="divMapTab" id="divMapTab87"> <div class="divFieldMap"> <select class="selSrc" id="selTargetnamex"><options....></select> </div> </div> It's way more complicated than that, and there are many select elements inside of each divFieldMap div. Here is my JS function that is building my string: function Save() { var sSaveString = ''; $('.divMapTab').each(function() { var thisId = this.id; $('.selSrc', "#" + thisId).each(function() { var thisSubId = this.id; //alert(thisSubId); <-- HERE IS THE PROBLEM var sTargetCol = thisSubId.replace('selTarget', ''); var sValue = this.val(); sSaveString += sTargetCol + '¸' + sValue + '·'; }); }); } On the line that has the alert box and the text "HERE IS THE PROBLEM" is that I'm trying to get the selected value of the "current" select input element, but the id of that element isn't unique (I thought it would be, but I screwed up). Is there a good way, inside of an "each" type of jQuery statement, to use "this" to get the exact select element that I really am looking for, even if it doesn't have a unique id?

  • Need help managing MySql connections

    - by David Jenings
    I'm having trouble finding a clear explanation of connection pooling. I'm building an app using the .NET connector I downloaded from mysql.com. The app only needs one db connection but will be running simultaneously on about 6 machines on my network. Normally, I'd create the connection at startup and just leave it. But I'm seeing lots of posts from people who say that's bad practice. Also I'm concerned about timeouts. My app will run 24/7 and there may be extended periods without database activity. I'm leaning toward the following: using (MySqlConnection conn = new MySqlConnection(connStr)) { conn.Open(); // use connection } But I'm not sure I understand what's going on in the background. Is this actually closing the connection and allowing gc to kill the object, or is there a built in pooling behavior that preserves the object and redelivers it the next time I try to create one? I certainly don't want the app reauthenticating across the network every time I hit the database. Can anyone offer me some advise?

  • C++ Function pointers vs Switch

    - by Perfix
    What is faster: Function pointers or switch? The switch statement would have around 30 cases, consisting of enumarated unsigned ints from 0 to 30. I could do the following: class myType { FunctionEnum func; string argv[123]; int someOtherValue; }; // In another file: myType current; // Iterate through a vector containing lots of myTypes // ... for ( i=0; i < myVecSize; i ++ ) switch ( current.func ) { case 1: //... break; // ........ case 30: // blah break; } And go trough the switch with func every time. The good thing about switch would also be that my code is more organized than with 30 functions. Or I could do that (not so sure with that): class myType { myReturnType (*func); string argv[123]; int someOtherValue; }; I'd have 30 different functions then, at the beginning a pointer to one of them is assigned to myType. What is probably faster: Switch statement or function pointer? Calls per second: Around 10 million. I can't just test it out - that would require me to rewrite the whole thing. Currently using switch. I'm building an interpreter which I want to be faster than Python & Ruby - every clock cycle matters!

  • How to use a variable in a function expression which is injected in a page?

    - by anonymous
    I'm trying to inject a function into a webpage via Chrome extension content script by: function inject(code) { var actualCode = '(' + code + ')();'; var script = document.createElement('script'); script.textContent = actualCode; (document.head||document.documentElement).appendChild(script); script.parentNode.removeChild(script); } var myObj = person; // myObj/person is passed in from elsewhere var fn = function() { alert(myObj.name); }; inject(fn); // myObj undefined My issue is, since fn is a function expression, I can't pass in myObj.personName. So my question is, how can I construct a function expression that includes a variable? Do I do some sort of string concatenation instead? I also tried to pass the object to the function, as follows: function inject(code, myObj) { var actualCode = '(' + code + ')(' + myObj +');'; ... But this did not work, and caused a "Uncaught SyntaxError: Unexpected identifier" error. Related: Building a Chrome Extension - Inject code in a page using a Content script

  • Custom stream wrappers, what could they be useful for in web applications?

    - by michael
    I suppose the concept is language agnostic, but I don't know what it's called in other languages. In PHP they're Stream Wrappers. In short, a wrapper class that allows manipulation of a streamable resource (resource that can be read to/written to/seek into, such as a file, a db, an url). For example, in a template engine (a view), upon including a template file such as: include "view.wrapper://path/to/my/template/file.phtml"; my custom wrapper, declared elsewhere and associated with "view.wrapper", would first intercepts the file to replace such things as short tags (<?=) with a more verbose counterpart (<?php echo). This allows developers to use short tags in views, even if the server isn't set to allow it. It can also be applied to the preprocessing of views pseudo syntax such as {@myVar} (e.g. replacing it with $this->myVar). This is only one application of custom stream wrappers, but the feature seems powerful enough to make me think that there are others that could make life a lot simpler for developers. What have you built, or thought about building, custom stream wrappers for? where have you seen some interesting implementations? I'm particularly interested in their applications in web development.

  • PHP transfer files from server to server in LAN

    - by cheapez
    So, I have 5-6 pages of requirements. I'm trying to build this application in PHP based on the requirements. I want to transfer files from one server to the other server in LAN, and then send a shell command to the other server to find out if the file has been transferred successfully. In php, I can transfer files using FTP, and send shell commands using SSH. Using the methods above, I will need to open connection to the server first, but I don't know the ftp server name, domain name, ip address, or anything like that. I only know the the server ID (I'm not sure what this ID is, but I guess it is like the computer's name). An example of the server ID is: "c23bap234" How do I open a connection with just that server ID? These servers are in the same building, have LAN connection, don't have connection to the outside world. These machines have PHP, Apache, ... installed. If my post doesn't make sense to you, it's because I'm a learner. I hope someone can help me on this. Thanks in advance.
