  • Data confusion - Selecting data in one DataGridView based on selection in another

    - by Logan Young
    This probably isn't the best way to do what I want, but I can't think of anything else to try... NB: I'm using Visual Basic.NET My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid. When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid. So, basically, I want to dynamically display data in one grid based on user selection in another grid. My code looks like this so far... Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick Try FlagsGrid.Visible = True ''// MsgBox(RulesGrid.CurrentCell.Value.ToString()) Dim sql As String = "SELECT * FROM ctblMKA_Status_Flags " + _ "WHERE intStatusID = '" & RulesGrid.CurrentCell.Value & "'" DSFlags = GetDS(sql) DSFlags.DataSetName = "FlagsDataSet" FlagsGrid.DataSource = DSFlags ProgressBar.Visible = False Catch ex As Exception MsgBox(ex.ToString) End Try End Sub I feel like I'm missing something here... Any ideas anyone?

  • How to avoid geometric slowdown with large Linq transactions?

    - by Shaul
    I've written some really nice, funky libraries for use in LinqToSql. (Some day when I have time to think about it I might make it open source... :) ) Anyway, I'm not sure if this is related to my libraries or not, but I've discovered that when I have a large number of changed objects in one transaction, and then call DataContext.GetChangeSet(), things start getting reaalllly slooowwwww. When I break into the code, I find that my program is spinning its wheels doing an awful lot of Equals() comparisons between the objects in the change set. I can't guarantee this is true, but I suspect that if there are n objects in the change set, then the call to GetChangeSet() is causing every object to be compared to every other object for equivalence, i.e. at best (n^2-n)/2 calls to Equals()... Yes, of course I could commit each object separately, but that kinda defeats the purpose of transactions. And in the program I'm writing, I could have a batch job containing 100,000 separate items, that all need to be committed together. Around 5 billion comparisons there. So the question is: (1) is my assessment of the situation correct? Do you get this behavior in pure, textbook LinqToSql, or is this something my libraries are doing? And (2) is there a standard/reasonable workaround so that I can create my batch without making the program geometrically slower with every extra object in the change set?

  • first major web app

    - by vbNewbie
    I have created a web app version of my previous crawler app and the initial form has controls to allow the client to make selections and start a search 'job'. These searches 'jobs' will be run my different threads created individually and added to a list to keep track of. Now the idea is to have another web form that will display this list of 'jobs' and their current status and will allow the jobs to be cancelled or removed only from the server side. This second form contains a grid to display these jobs. Now I have no idea if I should create the threads in the initial form code or send all user input to my main class which runs the search and if so how do I pass the the thread list to the second form to have it displayed on the grid. Any ideas really appreciated. Dim count As Integer = 0 Dim numThread As Integer = 0 Dim jobStartTime As Date Dim thread = New Thread(AddressOf ResetFormControlValues) 'StartBlogDiscovery) jobStartTime = Date.Now thread.Name = "Job" & jobStartTime 'clientName Session("Job") = "Job" & jobStartTime 'clientName thread.start() thread.sleep(50000) If numThread >= 10 Then For Each thread In threadlist thread.Join() Next Else numThread = numThread + 1 SyncLock threadlist threadlist.Enqueue(thread) End SyncLock End If this is the code that is called when the user clicks the search button on the inital form. this is what I just thought might work on the second web form if i used the session method. Try If Not Page.IsPostBack Then If Not Session("Job") = Nothing Then Grid1.DataSource = Session("Job") Grid1.DataBind() End If End If Finally

  • RIA Service - without database?

    - by Heko
    Helo! I need to write a RIA service to call Java webservices from Silverlight 3.0 app. I'm testing how stuff works and in my Web app I have a MyData class which has 2 properties (int ID, string Text): namespace SilverlightApplication1.Web { public class MyData { [Key] public int ID { get; set; } public string Text { get; set; } } } Then I wrote simple DomainService: [EnableClientAccess()] public class MyService : DomainService { public IQueryable<MyData> GetMyData(string Url) { // here I will call my WebService List<MyData> result = new List<MyData>(); result.Add(new MyData { ID = 1, Text = Url }); return result.AsQueryable(); } } } How can I get data into my SL app? Now I have this: namespace SilverlightApplication1 { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MyContext context = new MyContext(); } } } I called and load but nothink worsk (exceptions, or nulls)... I had Invoke annotation but MyData is not TEntity and I can't use Strings or other simple types as well... :/ I'm reading and reading posts and nothing works like it should.. Any help would be really appreciated. Thank you!

  • C# Freq. Table with Random Values

    - by Sef
    Hello, I am trying to write a frequency program that will represent a bar diagram (in console code). The problem is i have no idea how exactly to caculate this frequency or how do i exactly then give the bars different heights according to there frequency (trough calculation). The frequency height is capped at 21. (meaning the bars go from 1 to 21, so the max bar height would be for example 21 stars(* as display sign for the bar itself). A calculation i have so far (although not sure if correct) for frequency: This array takes the random values generated: for (int j = 0; j < T.Length; j++) { T[j] = (MaxHeight* T[j]) / Ber.GreatestElement(T); Console.Write("{0,7}", T[j]); } This results in values between 0 and 21 -- Based on the values my bars should give a certain height compared to all the other frequency values. (for example 8000 could have 21 in height where 39 could have 1). To represent this diagram i used 2 for loops to display height and width (keep in mind i only wish to use Using System; to keep it to the "basics"). for (int height= 1; height<= 21; height++) { for (int width= 0; width<= 10; width++) { if(...??) { Console.Write("{0,7}", bar); // string bar= ("*"); } else { Console.Write("{0,7}", empty); } } Console.WriteLine(); } So so far i have a entire field filled with * and the random values generated along with their frequency value (although i have no idea if the freq value is properly calculated). I assume i need a if (.....) in the second for but i cannot seem to get further then this. Thanks in advance!

  • wxPython: MainLoop() seems to hang

    - by BandGap
    Hi all, my problem stems from the use of wxApp as far as I can tell. Inside a litte subroutine I call a wx.MessageDialog to ask for a yes or no. I retrieve the answer an process some stuff acordingly. My example code below actually works (though it might be ugly) except that the Dialog box stays open after hitting one of the buttons... import wx from os import path def HasFile(filename): if path.isfile(filename ): app = wx.App() dial = wx.MessageDialog(None, 'Die Datei "'+filename+'" wurde gefunden.\nSoll sie eingelesen werden?', 'Bitte antworten', wx.YES_NO | wx.YES_DEFAULT | wx.ICON_QUESTION) result = dial.ShowModal() dial.EndModal(retCode=0) dial.Destroy() app.MainLoop() return result == wx.ID_YES else: return False So while the rest of the program does whatever is expected, the box just sits there. It also seems like my calls to matplotlib later on are producing errors (a Tkinter error to be precise), maybe because of the wx stuff? Edit: I tried to end the app with a call to app.Destroy(). This doesn't change the fact that the box is still there. When I issue a app.IsActive() afterwards the whole program exits (almost like a sys.exit())! How come? Edit 2: Adding a wxApp like this isn't a good idea since the other scripts get affected as well. Subsequent plotting commands don't get displayed and I don't know how to fix this. Thus I decided to remove the DialogBox alltogether.

  • Jquery ajax ($.ajax) not working on chrome. please help

    - by racky
    Hi, I need a little help to figure out why the following code does not work on google chrome 5/windows xp. It works well on all other browsers (IE, FF, Safri, Opera etc). Can someone shed some light around this? /* AJAX Request */ jq("#a-post-request").unbind("click").bind("click", function(e){ //jq("#loading").css({"display":"block"}); jq.ajax({ url: "search_data_table.html", type: "get", cache: false, error: function(){alert ("No data found for your search.");}, success: function(data){ jq("#search-results-table tbody").empty().append(data); jq("#search-results").css({"display":"block"}); jq("#search-results-table").trigger("update"); // this one is for the table sorter plugin // set sorting column and direction, this will sort on the first column. var sorting = [[0,0]];// this one is for the table sorter plugin // sort on the first column . jq("#search-results-table").trigger("sorton",[sorting]);// this one is for the table sorter plugin e.preventDefault(); } }); }); Many thanks, Racky

  • SFINAE and detecting if a C++ function object returns void.

    - by Tom Swirly
    I've read the various authorities on this, include Dewhurst and yet haven't managed to get anywhere with this seemingly simple question. What I want to do is to call a C++ function object, (basically, anything you can call, a pure function or a class with ()), and return its value, if that is not void, or "true" otherwise. #include <stdio.h> struct Foo { void operator()() {} }; struct Bar { bool operator()() { return false; } }; Foo foo; Bar bar; bool baz() { return false; } void bang() {} const char* print(bool b) { printf(b ? "true, " : "false, "); } template <typename Functor> bool magicCallFunction(Functor f) { return true; // lots of template magic occurs here... } int main(int argc, char** argv) { print(magicCallFunction(foo)); print(magicCallFunction(bar)); print(magicCallFunction(baz)); print(magicCallFunction(bang)); printf("\n"); }

  • Unable to add multiple textviews into linearLayout within a loop

    - by Adam
    for(int i=0;i<object.size();i++){ FeaturedSingleEvent event = (FeaturedSingleEvent) object.get(i); images.add(event.getImage()); LinearLayout info = new LinearLayout(this); info.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); TextView title = new TextView(this); title.setText(event.getTitle()); title.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(title); TextView by = new TextView(this); by.setText(event.getBy() + " " + event.getBy_name()); by.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(by); TextView summary = new TextView(this); summary.setText(event.getSummary()); summary.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(summary); layout.addView(info); if(i == 0){ info.setVisibility(View.VISIBLE); }else{ info.setVisibility(View.GONE); } } I'm attempting to have multiple LinearLayouts, only one being visible at a time, to create a slideshow. In a for loop, I create the layouts with their textViews, and set only the first one to be visible. The problem is that only one TextView seems to be displaying, ie. if everything but summary is deleted, then summary will display. As of right now, only title will display, because i'm assuming it's the first one. I'm most likely doing it wrong, so any help would be appreciated.

  • How to convert a byte array of 19200 bytes in size where each byte represents 4 pixels (2 bits per p

    - by Klinger
    I am communicating with an instrument (remote controlling it) and one of the things I need to do is to draw the instrument screen. In order to get the screen I issue a command and the instrument replies with an array of bytes that represents the screen. Below is what the instrument manual has to say about converting the response to the actual screen: The command retrieves the framebuffer data used for the display. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per byte arranged as 320x240 characteres. The data is sent in RLE encoded form. To convert this data into a BMP for use in Windows, it needs to be turned into a 4BPP. Also note that BMP files are upside down relative to this data, i.e. the top display line is the last line in the BMP. I managed to unpack the data, but now I am stuck on how to actually go from the unpacked byte array to a bitmap. My background on this is pretty close to zero and my searches have not revealed much either. I am looking for directions and/or articles I could use to help me undestand how to get this done. Any code or even pseudo code would also help. :-) So, just to summarize it all: How to convert a byte array of 19200 bytes in size, where each byte represents 4 pixels (2 bits per pixel), to a bitmap arranged as 320x240 characters. Thanks in advance.

  • Alternate colors on click with jQuery

    - by Jace Cotton
    I'm sure there is a simple solution to this, and I'm sure this is a duplicate question, though I have been unable to solve my solution particularly because I don't really know how to phrase it in order to search for other questions/solutions, so I'm coming here hoping for some help. Basically, I have spans with classes that assigns a background-color property, and inside those spans are words. I have three of these spans, and each time a user clicks on a span I want the class to change (thus changing the background color and inner text). HTML: <span class="alternate"> <span class="blue showing">Lorem</span> <span class="green">Ipsum</span> <span class="red">Dolor</span> </span> CSS: .alternate span { display : none } .alternate .showing { display : inline } .blue { background : blue } .green { background : green } .red { background : red } jQuery: $(".alternate span").each(function() { $(this).on("click", function() { $(this).removeClass("showing"); $(this).next().addClass("showing"); }); }); This solution works great using $.next until I get to the third click, whereafter .showing is removed, and is not added since there are no more $.next options. How do I, after getting to the last-child, add .showing to the first-child and then start over? I have tried various options including if($(".alternate span:last-child").hasClass("showing")) { etc. etc. }, and I attempted to use an array and for loop though I failed to make it work. Newb question, I know, but I can't seem to solve this so as a last resort I'm coming here.

  • How to get unique value in jquery?

    - by jquerier
    I am learning jquery. I have following chunk of code in a html file: <table width="100%"> <tr> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='1'><img src='images/1.gif'></a> </div> </td> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='2'><img src='images/2.gif'></a> </div> </td> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='3'><img src='images/3.gif'></a> </div> </td> </tr> What I want to do is, when I click any of the image, I can get the value, so that I can display the information. For example, I click the id=1, then I will display information on id1 in somewhere else. I tried this: $("a#get_this").click(function(){ var id = $('input[type=hidden]#id').val(); window.alert("You have chosen the id: " + id); }); It always return id: 1 to me.

  • Debugging scripts loaded with GroovyShell (in eclipse)

    - by MSh
    I am working with eclipse and groovy plug in. I am building a test harness to debug and test groovy scripts. The scripts are really simple but long, most of them just if/else/return. I figured out that I can call them using GroovyShell and Bindings to pass in the values. The problem is that, while I can call the script and get the results just fine, I CAN NOT step in there with the debugger. Breakpoints in those scripts are not active. Is there a way to debug the scripts? Maybe I should use something other than GroovyShell? I really don't want to modify the scripts by wrapping them into functions, and then calling those functions from my test classes. That's how I am using Binding and GroovyShell: def binding = new Binding(); binding.lineList = [list1]; binding.count = 5; def shell = new GroovyShell(binding); def result = shell.evaluate(new File("src/Rules/checkLimit.groovy"));

  • Updating table row by given id with jQuery

    Hello all! I need to update a specific table row (via tr id="unique_key") after a successful AJAX call. HTML fragment: <a name=\"p{$product_id}\" class=\"tr{$product_id}\"></a> <tr id="p{product_id}" class="item-row"> <td><h3>{product_id}</h3><a rel="facebox" href="ajax_url">{product_name}</a></td> <td>{image_information}</td> <td>{image_sortiment}</td> <td>{product_status}</td> </tr> Javascript: // AJAX Call success: function(msg){ $('#p' + prod_id).remove(); $('.tr' + prod_id).after(msg); $('#p' + prod_id + ' a[rel*=facebox]').facebox(); } ... What happens: The table row removed Anchors grouped into one single row (not before their <tr>'s) so my 'hook' disappears AJAX result inserted over the whole table (after my 'hook' but still a wrong place) What's wrong with my idea? How can i force jQuery to 'overwrite' the required table row?

  • XML digital signature interface

    - by yeekang
    I am trying to call a WebService and it requires me to prepare an XML digital signature interface. I came across this website and it shows how to sign an XML document. My problem now is that I do not create the XML document myself. My code is as follows: string myResult; GenericWS.ServicesService a = new GenericWS.ServicesService(); GenericWS.Service2 b = new GenericWS.Service2(); b.Something = "3"; X509Certificate cert = X509Certificate.CreateFromCertFile("C:\\somepath\\somecert.cer"); a.ClientCertificates.Add(cert); ServicePointManager.ServerCertificateValidationCallback = delegate (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; myResult= a.WSRequest(b).WSReturnValue.ToString(); Label1.Text = myResult; Basically, the WSRequest() will generate the body of the SOAP message. However, in order to sign the SOAP message, I need to pass in the XML file that needs to be signed. I tried to serialize the object and cast it as XML and pass it into the signature interface but I do not have another method that I can invoke to call the webmethod. Is there any other solution?

  • JQuery cycle plugin + PNG overlay + Image alt text as title conflict

    - by Dave
    I am trying to achive the following: Create an image gallery using the JQuery Cycle plugin that shows images with titles (taken from the alt text) Each image has a PNG absolutley posiioned over the top to achieve rounded corners effect Here's my gallery HTML: <div id="slideshow" class="pics"> <div class="photo-container" > <img src="/path/to/image" alt="alt text as title" /> <img class="mask" src="path/to/mask" /> </div> </div><!-- /slideshow --> <div id="title"></div> Here's my Jquery gallery function: $(function() { $('#slideshow').after('<div id="nav" class="nav"><span style="margin: 0 5px 0 30px;">next image</span>').cycle({ fx: 'fade', timeout: 0, cleartypeNoBg: true, pager: '#nav', next: '#slideshow', before: onBefore }); function onBefore() { $('#title').html(this.alt); } $('#nav a').after('<span>&gt;</span>') }); </script> Here is my CSS that handles the mask: .photo-container { position: relative; display: block; overflow:hidden; border: none; } img.mask { position: absolute; top: 0; left: 0; overflow:hidden; border: none; } The above does not output the alt text into the "title" div. When I remove the mask, it works: <div id="slideshow" class="pics"> <img src="/path/to/image" alt="alt text as title" /> </div><!-- /slideshow --> <div id="title"></div> Any ideas why the additonal div / image is casuing the title to not display?

  • [jQuery] Sort contents alphabetically

    - by James
    So I am appending the following after an AJAX call, and this AJAX call may happen several time, returning several data items. And I am trying to use Tinysort [http://plugins.jquery.com/project/TinySort] to sort the list everytime, so the new items added are integrated nicely and sorted alphabetically. It unfortunately doesn't seem to be working. Any ideas? I mean, the data itself is being correctly appended, but unfortunately the sorting isn't occurring. var artists = []; $.each(data.artists, function(k, v) { artists.push('<section id="artist:' + v.name + '" class="artist"><div class="span-9"><img alt="' + v.name + '" width="34" height="34" class="photo" src="' + v.photo + '" /><strong>' + v.name + '</strong><br/><span>' + v.events + ' upcoming gig'); if (v.events != 1) { artists.push('s'); } artists.push('</span></div><div class="span-2 align-right last">Last</div><div class="clear"></div></section>'); }); $('div.artists p').remove(); $('div.artists div.next').remove(); $('div.artists').append(artists.join('')).append('<div class="next"><a href="#">Next</a></div>'); $('div.artists section').tsort('section[id]', {orderby: 'id'}); Thanks!

  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • Dijit.Dialog irregular behaviour of scroll bar making dialog box unusable

    - by arachnica
    I use a dojo dialog box to display a page pulled from another part of the site. The page being pulled is long - so I use the css attribute: `max-height: 900px; overflow:auto; To make sure it displays properly. For a long page, it displays a 900px high dialog box with a scrollbar down the right hand side side. However the scrollbar is going up to the dialog box title and shifting the close box icon to the left. In internet explorer, when a user moves his mouse of the close box icon, it moves to the right. If you move your mouse to the right it moves left - so you can never actually close the box with the icon. I have tried clearing the content in the box and just making it very long, and the same thing still happens. Oddly enough, if I close the window using esc and click pull up the dialog box again, it works fine. Any way I can make it display properly at all times. I am using Dojo version 1.3. Thanks

  • Need method to seek next/previous records id without cycling through all records.

    - by dqhendricks
    I am using MySQL and PHP. I have a MySQL blog post result set with id fields, and publish_date fields. I display one blog post per page, and the script knows which blog post to display based on $_GET['id'], which correlates to each blog entry's id field. I would like to reference them by id in the url, because I would like each blog post to have a perminant url. I would like to order the blog posts by publish date (descending). Now, on each page there will be next and previous links, which contain the $_GET['id'] value for the next and previous blog posts. How can I figure out what the id of the next and previous blog posts (determined by it's publish_date order) without cycling through each mysql result row? I can't mysql_data_seek(), because I do not know the row index of the current blog post id. I do not want to store a row index in a GET variable because the urls would no longer be perminant. I obviously cannot store the row index in a SESSION variable because then direct links to specific blog posts would have broken next and previous links. Any suggestions would be greatly appreciated.

  • Does IE completely ignore cache control headers for AJAX requests?

    - by Joshua Hayworth
    Hello there, I've got, what I would consider, a simple test web site. A single page with a single button. Here is a copy of the source I'm working with if you would like to download it and play with it. When that button is clicked, it creates a JavaScript timer that executes once a second. When the timer function is executed, An AJAX call is made to retrieve a text value. That text value is then placed into the DOM. What's my problem? IE Caching. Crack open Task Manager and watch what happens to the iexplorer.exe process (IE 8.0.7600.16385 for me) while the timer in that page is executing. See the memory and handle count getting larger? Why is that happening when, by all accounts, I have caching turned off. I've got the jQuery cache option set to false in $.ajaxSetup. I've got the CacheControl header set to no-cache and no-store. The Expires header is set to DateTime.Now.AddDays(-1). The headers are set in both the page code-behind as well as the HTTP Handler's response. Anybody got any ideas as to how I could prevent IE from caching the results of the AJAX call? Here is what the iexplorer.exe process looks like in ProcessMonitor. I believe that the activity shown in this picture is exactly what I'm attempting to prevent.

This application uses Spring MVC and using the domain objects in the presentation layer is very messy so I think I should use DTO's that go to and from my service layer so that these match what I need in my views. Now lets assume I have a CarLease entity whose properties are not simple java primitives but it's composed with other entities like Make, Model, etc public class CarLease { private Make make; Private Model model; . . . } most properties are in this fashion and they are selectable using drop down selects on the jsp view, each will post back an ID to the controller. Now considering some standard use cases: create, edit, display How would you go about modeling the presentation DTO's to be used as form backing objects and communication between presentation and service layers?? Would you create a different DTO for each case (create, edit, display), would you make DTO's for the complex attributes? if so where would you translate the ID to entity? how and where would you handle validation, DTO/Domain assembly, what would you return from service layer methods? (create, edit, get) As you can see, I now I will benefit by separating my view from the domain objects (very complex with lots of stuff I don't need.) but I am having a hard time finding any real world examples and best practices for this. I need some architecture guidance from top to bottom, please keep in mind I will use Spring MVC in case that may leverage on your anwser. thanks in advance.

  • FBML wallpost by clicking on image or button

    - by psaha
    Hello, I'm creating one facebook application with FBML. What I want is: I have several images like, <fb:tag name="img"> <fb:tag-attribute name="src">http://My_Img_Url_1.jpg</fb:tag-attribute> </fb:tag> <fb:tag name="img"> <fb:tag-attribute name="src">http://My_Img_Url_2.jpg</fb:tag-attribute> </fb:tag> While I click on the image it should open one popup "post to wall" or "Post to your Friend's wall" with the corresponding image My_Img_Url_n.jpg. I can use FBML share button like: METHOD-1 <fb:share-button class="meta"> <meta name="title" content="Image_TITLE"/> <meta name="description" content="Image_Descrip"/> <link rel="image_src" href="http://My_Img_Url_1.jpg"/> <link rel="target_url" href="Some_Target_URL"/> </fb:share-button> OR, METHOD-2: I can call fb:ui <script> FB.init({ appId:'111111111111111', cookie:true, status:true, xfbml:true }); FB.ui({ method: 'feed', name: '', link: '', picture: 'http://My_Img_Url_1.jpg' }); </script> Now the questions are: If I click on any image it will call either METHOD-1 or METHOD-2 and it will popup with that image. How can I do that? If I use <fb:multi-friend-input /> for posting to friend's wall, How can I do?
