  • Attachment_fu file saving problem

    - by Anand
    Attachment_fu plugin is kind of old, but I have to modify an old app and I can't use another plugin like paperclip etc. So here's the code without further ado Submissions table structure --------------------------- | content_type | varchar(255) | YES | | NULL | filename | varchar(255) | YES | | NULL app/models/submission.rb ------------------------ has_attachment :storage => :file_system, :path_prefix => 'public/submissions', :max_size => 2.megabytes, :content_type => ['application/pdf', 'application/msword', 'text/plain'] app/models/user.rb ------------------ has_one :submission, :dependent => :destroy app/views/user/some_action.html.erb ----------------------------------- <% form_for :user, :url => { :action => "some_action" }, :html => {:multipart => true} do |f| %> .... <%= file_field_tag "submission[uploaded_data]" %> <%end%> app/controllers/user_controller.rb ---------------------------------- @user = User.find_user(session[:user_id]) @submission = @user.submission if request.post? @submission.uploaded_data = params[:submission][:uploaded_data] end When the form is submitted, the database fields "content_type" and "filename" get updated and display the correct values, but the file does not appear in public/submissions/ directory. I have checked the permissions on the submissions directory. What am I missing? Many Thanks

  • [iphone,twitter] Accessing the Twitter API through a proxy using NSURLConnectionsm, OAuth problem

    - by akaii
    I'm having no problems with sending an update directly via hxxps://api.twitter.com/, but the app (for the Iphone, I'm using NSURLConnections) I'm working is supposed to allow the user to select a preferred proxy (e.g. hxxps://twitter-proxy.appspot.com/api/ or hxxps://nest.onedd.net/api/), and I keep getting a 401 error (Failed to validate oauth signature and token) whenever I try to get an access token via these proxies. Even though I send my POST request to the proxy, I am still using the direct url for the api (https:// api.twitter.com/[rest api path]) in the base string. Despite the 401 error message above, the status code I'm actually getting from connection:didReceiveResponse: is 200, probably because it was able to successfully contact the proxy... Is there anything else that I need to consider when using a proxy to access the API? Should anything in the authorization header change, for example? Or the base string? I can manage to connect via Basic Auth without issue, but support for that will be dropped in a month. On a somewhat unrelated note... What are the possible causes of Twitter's error 403, and how do you distinguish between them? Is the only way to differentiate an error due to exceeding the status update limit for an hour (150 per hour) vs for a day (1000 per day) by checking the string reply returned in the response? Is there any way for me to simulate a status update limit error without going through the motions of actually sending 150/1000 tweets?

  • Rails does not display error messages on a form in a custom method

    - by slythic
    Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

  • OpenOffice in Java

    - by user156073
    I need a Java interface to the OpenOffice document conversion which would equal to a manual (Open... and then Save As...) as well as access to the PDF generation. The following are some example of what I want to achieve. 1) Open one type of document (fx. OpenOffice Writer document or Microsoft Office document) onto memory and save it in another supported format. 2) Open one type of document into memory and export it as PDF. I have gone through http://api.openoffice.org but didn't get any material which can help me to get started. I also tried JODConverter but it requires me to run OpenOffice as a service. I wold prefer to include all the core functionality of OpenOffice in one JAR file so that that the user can use my application without installing or running openoffice on their PC. What would be a URL/code snippet from where I can get tutorials to get started? Also do I have to add some JAR files? Will the application work even if I don't have OpenOffice installed on my PC?

  • Mixing RewriteRule and ProxyPass in Apache

    - by Taylor L
    I was working on debugging an issue today related to mixing mod_proxy and mod_rewrite together and I ended up having to use balancer://mycluster in the RewriteRule in order to stop receiving a 404 error from Apache. I have two questions: 1) Is there any other way to get the rewritten URL to go through the balancer without adding balancer://mycluster into the RewriteRule? 2) Is there a way to define all the parameters I defined in ProxyPass (stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off) in either the <Proxy> or RewriteRule? I'm concerned the requests that match the new RewriteRule won't load balance in the same fashion as those that go through ProxyPass (like /app1/something.do)? Below are the relevant sections of the httpd.conf. I am using Apache 2.2. <Proxy balancer://mycluster> Order deny,allow Allow from all BalancerMember ajp://my.domain.com:8009 route=node1 BalancerMember ajp://my.domain.com:8009 route=node2 </Proxy> ProxyPass /app1 balancer://mycluster/app1 stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off ProxyPassReverse /app1 ajp://my.domain.com:8009/app1 ...

  • ajax to php to curl and back..

    - by pfunc
    I am trying to make an ajax call to a php script. The php script calls an rss feed using curl, gets the data, and returns the data to the funciton. I keep getting an error "Warning: Wrong parameter count for curl_error() in" .... Here is my php code:1 $ch = curl_init() or die(curl_error()); curl_setopt($ch, CURLOPT_URL, $feed); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data1 = curl_exec($ch) or die(curl_error()); echo $data1; and the ajax call: $.ajax({ url: "getSingleFeed.php", type: "POST", data: "feedURL=" + window.feedURL, success: function(feed){ alert(feed); }}); I tested all the variables, they are being passed correctly, I can echo them out. But this line: $data1 = curl_exec($ch) or die(curl_error()); is what is giving me the error. I am doing the same thing with curl on other pages, just without ajax, and it is working fine. Is there anything special I need to do with ajax to do this?

  • How do I build a JSON object to send to an AJAX WebService?

    - by Ben McCormack
    After trying to format my JSON data by hand in javascript and failing miserably, I realized there's probably a better way. Here's what the code for the web service method and relevant classes looks like in C#: [WebMethod] public Response ValidateAddress(Request request) { return new test_AddressValidation().GenerateResponse( test_AddressValidation.ResponseType.Ambiguous); } ... public class Request { public Address Address; } public class Address { public string Address1; public string Address2; public string City; public string State; public string Zip; public AddressClassification AddressClassification; } public class AddressClassification { public int Code; public string Description; } The web service works great with using SOAP/XML, but I can't seem to get a valid response using javascript and jQuery because the message I get back from the server has a problem with my hand-coded JSON. I can't use the jQuery getJSON function because the request requires HTTP POST, so I'm using the lower-level ajax function instead: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/HBUpsAddressValidation/AddressValidation.asmx/ValidateAddress", data: "{\"Address\":{\"Address1\":\"123 Main Street\",\"Address2\":null,\"City\":\"New York\",\"State\":\"NY\",\"Zip\":\"10000\",\"AddressClassification\":null}}", dataType: "json", success: function(response){ alert(response); } }) The ajax function is submitting everything specified in data:, which is where my problem is. How do I build a properly formatted JSON object in javascript so I can plug it in to my ajax call like so: data: theRequest I'll eventually be pulling data out of text inputs in forms, but for now hard-coded test data is fine. How do I build a properly formatted JSON object to send to the web service?

  • Authorization and Jquery dialog problem.

    - by bbrepols
    Hi, I have a little problem with a Jquery dialog for an action that requires a role. In my example, the user can click on a delete button and must confirm the action. In my controller, the Delete action requires a role, if the user is in the required role, the object is deleted. The problem: How to alert the user if * the element was deleted (redirect to the Index view) * there was an error (alert with the message) * he doesn't have the rights to delete (alert with the message) Before using the authorize filter, the delete action returned a JSON with a Boolean that indicates if there was an error, an URL to redirect on success and a message to alert on error. As I can't return a JSON from my filter, I created an other method with the authorize filter that returns a partial view with the confirm content. If the user doesn't have the rights, the filter returns a partial view with an unauthorized exception content. The problem: How to distinct which partial view was returned. When I create the dialog, I need to know for the buttons function. Thanks!

  • 2 different routes on one page?

    - by Dejan.S
    Hi I'm pretty new with MVC2 or MVC in general. If it's one thing I get caught up with it's routes. Like now I got this scenario. Im going from the regular site to Admin. My navigation is the same partialview on both I just do a check which data to render something like this. <% if (!Request.RawUrl.Contains("Admin")){%> <% foreach (var site in Model) { %> <%= Html.MenuItem(site.BelongSite, "Sida", "Site", site.BelongSite) %> | <%} %> <%} else {%> <%= Html.ActionLink("Konfig", "Konfigurera", "Admin") %> <% } %> My route looks like this routes.MapRoute( "Admin", // Route name "Admin/{action}/{name}", // URL with parameters new { controller = "Admin", action = "konfigurera", name = UrlParameter.Optional } // Parameter defaults ); On my View called Konfigurera I got Edit sites and they use the route above and it works great. The navigation tho dont get no action assigned to it. It's just <a href='Admin/'> The navigation is in the shared folder, and it is a strongly typed. Any Ideas? I been struggling with this for about a hour now Thanks for any input

  • jQuery ajax post failing in asp

    - by Dave Kiss
    hey guys, this might be really stupid, but hopefully someone can help. I'm trying to post to an external script using ajax so i can mail the data, but for some reason my data is not making it to the script. $(document).ready(function() { $("#submitContactForm").click(function () { $('#loading').append('<img src="http://www.xxxxxxxx.com/demo/copyshop/images/loading.gif" alt="Currently Loading" id="loadingComment" />'); var name = $('#name').val(); var email = $('#email').val(); var comment = $('#comment').val(); var dataString = 'name='+ name + '&email=' + email + '&comment=' + comment; $.ajax({ url: 'http://www.xxxxx.com/demo/copyshop/php/sendmail.php', type: 'POST', data: '?name=Dave&[email protected]&comment=hiiii', success: function(result) { $('#loading').append('success'); } }); return false; }); }); the php script is simple (for now - just wanted to make sure it worked) <?php $name = $_POST['name']; $email = $_POST['email']; $comment = $_POST['comment']; $to = '[email protected]'; $subject = 'New Contact Inquiry'; $message = $comment; mail($to, $subject, $message); ?> the jquery is embedded in an .aspx page (a language i'm not familiar with) but is posting to a php script. i'm receiving emails properly but there is no data inside. am i missing something? i tried to bypass the variables in this example, but its still not working thanks

  • Mac vs. Windows Browser Font Height Rendering Issue

    - by cdmckay
    I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

  • C# webservice async callback not getting called on HTTP 407 error.

    - by Ben
    Hi, I am trying to test the use-case of a customer having a proxy with login credentials, trying to use our webservice from our client. If the request is synchronous, my job is easy. Catch the WebException, check for the 407 code, and prompt the user for the login credentials. However, for async requests, I seem to be running into a problem: the callback is never getting called! I ran a wireshark trace and did indeed see that the HTTP 407 error was being passed back, so I am bewildered as to what to do. Here is the code that sets up the callback and starts the request: TravelService.TravelServiceImplService svc = new TravelService.TravelServiceImplService(); svc.Url = svcUrl; svc.CreateEventCompleted += CbkCreateEventCompleted; svc.CreateEventAsync(crReq, req); And the code that was generated when I consumed the WSDL: public void CreateEventAsync(TravelServiceCreateEventRequest CreateEventRequest, object userState) { if ((this.CreateEventOperationCompleted == null)) { this.CreateEventOperationCompleted = new System.Threading.SendOrPostCallback(this.OnCreateEventOperationCompleted); } this.InvokeAsync("CreateEvent", new object[] { CreateEventRequest}, this.CreateEventOperationCompleted, userState); } private void OnCreateEventOperationCompleted(object arg) { if ((this.CreateEventCompleted != null)) { System.Web.Services.Protocols.InvokeCompletedEventArgs invokeArgs = ((System.Web.Services.Protocols.InvokeCompletedEventArgs)(arg)); this.CreateEventCompleted(this, new CreateEventCompletedEventArgs(invokeArgs.Results, invokeArgs.Error, invokeArgs.Cancelled, invokeArgs.UserState)); } } Debugging the WS code, I found that even the SoapHttpClientProtocol.InvokeAsync method was not calling its callback as well. Am I missing some sort of configuration?

  • Grayscale image with colored spotlight in JavaFX

    - by DaUltimateTrooper
    I need a way to have a gray scale image in an ImageView and on mouse moved if the cursor position is in the ImageView bounds to show a colored spotlight on the mouse position.

  • jQuery: Stop browser scrolling on event update beyond the fold?

    - by neezer
    I have several links at the bottom of my page that update content at the top of my page (more than a viewport away). Here's the gist of what the update looks like: $('#private-photo div').fadeOut(function() { $(this).html('<%= escape_javascript(image_tag current_user.private_photo.image.url(:profile)) %>'); }).fadeIn(); Basically it's just fading out the old content and fading in the new content. My problem is that when this happens, the browser window automatically scrolls up just far enough so that the bottom of the updated content (#private-photo div) appears at the top of the browser viewport. I do not want this to happen. I want the content to be updated (still fading in and out), but without the browser viewport realigning its focus. I want to keep the animation because if the user has a big enough screen, or if they are using a link closer to the top of the page, I still want them to see the animation. Any ideas about how to prevent the browser from scrolling as described? If not, any suggestions for workarounds? FYI, I have this same problem in Safari 4, Chrome (for Mac), & Firefox 3.5. EDIT: Here's the link that calls the update action, which is itself inside a Colorbox: $('a.edit-photo').colorbox({ title: function() { return 'Edit Photo in ' + $(this).attr('rel'); }, overlayClose: false, onComplete: function() { $('#edit-photo-modal').submit(function(e) { $('#photo_submit').after('<span id="saving">Saving...</span>'); e.preventDefault(); $.post($(this).attr('action'), $(this).serialize(), function() { $('#edit-photo-modal #saving').text('Saved!'); }, "script"); }); } }); The lightbox opens, presents a form fetched through an AJAX request, then (on submit) triggers the update action mentioned above. I had these links outside of the Colorbox in an earlier design revision, and they exhibited the same problem, so I've ruled out Colorbox itself as a cause. If you need anymore info, let me know!

  • Image Grabbing with False Referer

    - by Mr Carl
    Hey guys, I'm struggling with grabbing an image at the moment... sounds silly, but check out this link :P http://manga.justcarl.co.uk/A/Oishii_Kankei/31/1 If you get the image URL, the image loads. Go back, it looks like it's working fine, but that's just the browser loading up the cached image. The application was working fine before, I'm thinking they implemented some kind of Referer check on their images. So I found some code and came up with the following... $ref = 'http://www.thesite.com/'; $file = 'theimage.jpg'; $hdrs = array( 'http' = array( 'method' = "GET", 'header'= "accept-language: en\r\n" . "Accept:application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*\/*;q=0.5\r\n" . "Referer: $ref\r\n" . // Setting the http-referer "Content-Type: image/jpeg\r\n" ) ); // get the requested page from the server // with our header as a request-header $context = stream_context_create($hdrs); $fp = fopen($imgChapterPath.$file, 'rb', false, $context); fpassthru($fp); fclose($fp); Essentially it's making up a false referrer. All I'm getting back though is a bunch of gibberish (thanks to fpassthru) so I think it's getting the image, but I'm afraid to say I have no idea how to output/display the collected image. Cheers, Carl

  • a:hover background-postition problem

    For some reason, I am not entirely sure why, but the following is not working. The background position simply stays the same on hover. I cannot figure out why. I could do it another way, but I would like to try and get to the bottom of why it does not work. #nav a:link, #nav a:visited { background:url(../img/nav-sprite.png) no-repeat; display:block; float:left; height:200px; padding:10px; text-indent:-9999px; border:solid 1px red; } #nav a#home { background-position:-10px 0px; width:30px; } #nav a#about-us { background-position:-85px 0px; width:45px; } #nav a:hover { background-position:1px -15px; } Does anybody know what could be causing this?

Here is the complete code -- import java.sql.*; import java.util.ArrayList; import java.util.Collections; public class Jdbcexample1 { /** * @param args */ public static void main(String[] args) { Connection con = null; try { Class.forName("com.mysql.jdbc.Driver").newInstance(); con = DriverManager.getConnection("jdbc:mysql:///test", "root", "*****"); //String url = "jdbc:msql://200.210.220.1:1114/Demo"; //Connection conn = DriverManager.getConnection(url,"",""); Statement stmt1 = con.createStatement(); Statement stmt2 = con.createStatement(); Statement stmt3 = con.createStatement(); Statement stmt4 = con.createStatement(); ResultSet rs0; ResultSet rs; ResultSet rs1; ResultSet rs2; String name; String hIx; int hIxInt; StringBuffer sb = new StringBuffer(); String affiliationSmall; ArrayList<String> affiliation = new ArrayList<String>(); ArrayList<Float> matchValues = new ArrayList<Float>(); ArrayList<Integer> hixValues = new ArrayList<Integer>(); ArrayList<Integer> idValues = new ArrayList<Integer>(); boolean moreFlag = false; String queryString; int tmpIdx; String name1; //get the hix at that index where the similarity is maximum int tmpHidx = 0; int tmpHix = 0; int id = 0; int count; int tmpidIdx = 0; //rs = stmt.executeQuery("SELECT id FROM libra.researchint WHERE id = 910887"); // Get name, affiliation , hIx from smalldb //rs = stmt1.executeQuery("SELECT name,aff,hIx FROM libra.smalldb"); // String cursorName = "OUR_CURSOR"; // stmt1.setCursorName(cursorName); //rs = stmt1.executeQuery("SELECT name,aff,hIx FROM libra.smalldb for update"); rs = stmt1.executeQuery("SELECT hIx FROM libra.smalldb for update"); rs0 = stmt2.executeQuery("SELECT name,aff FROM libra.smalldb"); while ( rs.next() && rs0.next() ) { //String lastName = rs.getString("id"); hIx = rs.getString("hIx"); hIxInt = Integer.parseInt(hIx); //if hIx if (hIxInt==-1) continue; //name = rs.getString("name"); name = rs0.getString("name"); name1 = new String(name); System.out.println(name); //affiliationSmall = rs.getString("aff"); affiliationSmall = rs0.getString("aff"); //name = "\"" +name+ "\""; // Get matching names from large faculty table //String queryString = "SELECT id,name,hIx FROM libra.faculty WHERE name = " +name; //name = does not work names are similar but not same (in faculty and // smalldb) String query = "SELECT id,name,hIx FROM libra.faculty WHERE name like ?"; //String query = "SELECT id,name,hIx FROM libra.faculty for update of hIx WHERE name like ?"; PreparedStatement prepStmt = con.prepareStatement(query); String[] nameArr = name.split(" "); StringBuffer tmpSb = new StringBuffer(); for(int idx = 0;idx<nameArr.length;idx++) { tmpSb.append(nameArr[idx] + "%"); } name = tmpSb.toString(); prepStmt.setString(1, name); rs1 = prepStmt.executeQuery(); //Try to get matching names from faculty big db //Execute the query on faculty table //rs1 = stmt2.executeQuery(queryString); if(rs1.isClosed()) continue; count = 0; matchValues.clear(); affiliation.clear(); while(rs1.next()) { //name = rs1.getString("name"); id = Integer.parseInt(rs1.getString("id")); //idValues.add(id); tmpHix = Integer.parseInt(rs1.getString("hIx")); queryString = "SELECT aff FROM libra.affiliation WHERE id = "+id; rs2 = stmt3.executeQuery(queryString); //affiliation = rs1.getString("aff"); sb.delete(0, sb.length()); while (rs2.next()) { //Concatenate it to the same string using a stringbuffer sb.append(rs2.getString("aff")); //affiliation.add(rs2.getString("aff")); } affiliation.add(sb.toString()); count++; // if(count1) // { // moreFlag = true; // //Call fuzzy match function, store the distance values and select the // //affiliation that has the minimum distance from affiliationSmall // // //problem is here, affiliation.get Index: 2, Size: 2 // // matchValues.add(fuzzyMatch(affiliationSmall,affiliation.get(count))); // hixValues.add(tmpHix); // idValues.add(id); // } }//end of while rs1 -> faculty rs1.close(); int idx = 0; if(count>1) { moreFlag = true; //Call fuzzy match function, store the distance values and select the //affiliation that has the minimum distance from affiliationSmall //problem is here, affiliation.get Index: 2, Size: 2 matchValues.add(fuzzyMatch(affiliationSmall,affiliation.get(idx))); hixValues.add(tmpHix); idValues.add(id); idx++; } if(moreFlag) { Object obj = Collections.max(matchValues); float maxVal = Float.parseFloat(obj.toString()); //int tmpIdx = matchValues.indexOf(new Float(maxVal)); //get the index at which similarity between affiliation strings is maximum, //as returned by fuzzyMatch //int tmpIdx = matchValues.indexOf(maxVal); tmpIdx = matchValues.indexOf(maxVal); //get the hix at that index where the similarity is maximum //int tmpHidx = hixValues.get(tmpIdx); tmpHidx = hixValues.get(tmpIdx); tmpidIdx = idValues.get(tmpIdx); //update the smalldb table String updateQ = "UPDATE libra.smalldb SET hIx = ?

  • Can I force Apache 2.2 connection close from inside a C module?

    - by Amos Shapira
    Hello, We'd like to have a more fine-grained control on the connections we serve in a C++ Apache 2.2 module (on CentOS 5). One of the connections needs to stay alive for a few multiple requests, so we set "KeepAlive" to "On" and set a short keep-alive period. But for every such connection we have a few more connections from the browser which we don't need to leave behind and instead want to force them to close after a single request. Some of these connections are on different ports (so we can distinguish them by port, since KeepAlive can be set per virtual host) and some request a different URL (so we can tell from the path and parameters that we don't want to leave them behind). Also for the one we do want to keep alive, we know that after a certain request we'd like to close it too. But so far the only way we found to "cancel" the keep-alive is to send a polite "Connection: close" header to the client. If the client is not well behaved, or malicious, then they can keep it open and waste our resources. Is there a way to tell Apache to close the connection from the server side? The documentation advises against just plain close(2) call on the socket since Apache needs to do some clean up before that's done. But is there some API or a trick to "override" the static "KeepAlive On" configuration dynamically (and convince Apache to call close(2))? Thanks.

  • How to get notified about changes on SharePoint groups.

    - by Flo
    Hi, I'm actual looking for a way to get notified about any changes on a SharePoint group. First I though I would be able to this by attaching a event handler to some kind of group list. But unfortunately there are no such list representing SharePoint groups. My second attempt was to bind a event handler to the content type SharePointGroup but this didn't work either. So are there any other options to get notified about events on a SharePoint group? Bye, Flo EDIT: Thanks for the reply so far. I forgot to mention that I've already googled and read about the user information list. Sorry. First I found a forum entry where they post the relative URL to the user information list (_catalogs/users/simple.aspx). When I'm using this link to see the list,it only contains users and no groups. I don't know but perhaps this link does some filtering on the list. The other information I found about in several blog and forum posts was that a event handler attached to the user information list are not fired up on an events. I have to admit after reading that it doesn't work so many times and even on MSDN (http://msdn.microsoft.com/en-us/library/aa979520.aspx), I didn't try it on my own. The problem attaching the event handler to the content type wasn't the attaching thing, the handler simply didn't get fired when I for example changed a group name or deleted a user from the group. I don't have an idea why the handler doesn't get called I pretty sure I implemented the right methods and attached them to the right events. Any other suggestions how to get informed about changes on SharePoint groups?

  • svnsync loses revision properties although hook installed

    - by roesslerj
    Hello all! I have a pretty weird problem. We have setup an SVN-Mirror via cronjob (because it needs to go from inside to outside of a firewall, so no post-commit-hook possible) and svnsync. We installed a pre-revprop-hook just as told. Everything seems to work fine, except that it doesn't. E.g. when manually executing the script. # svnsync --non-interactive sync file://<path-to-mirror> --source-username <usr> --source-password <pwd> Committed revision 19817. Copied properties for revision 19817. No error, no complaints. But if checking for the revision properties it says: # svnlook info <path-to-mirror> 0 # svn info -r HEAD file://<path-to-mirror> 2>&1 Path: <root-of-mirror> URL: file://<path-to-mirror> Repository Root: file://<path-to-mirror> Repository UUID: <uid> Revision: 19817 Node Kind: directory Last Changed Rev: 19817 So somehow the author and timestamp information gets lost. But we need that information for our internal processes. Since no error or warning is produced I have absolutely no idea even where to start to look. Everything is local (except for the remote master), so there are no server-logs to look at. I also tried to manually recopy via svnsync copy-revprops (http://chestofbooks.com/computers/revision-control/subversion-svn/svnsync-Copy-revprops-Ref-svnsync-C-Copy-revprops.html). It says Copied properties for revision 19885. But when I query them, it's just the same. Any ideas how I could approach that problem, or even better -- how to solve it? Any ideas appreciated.

  • jqGrid : "All in One" approach width jqGridEdit Class > how to set a composite primary key ?

    - by Qualliarys
    Hello, How to set a composite primary key for a "All in One" approach (grid defined in JS file, and data using jqGridEdit Class in php file) ? Please, for me a composite primary key of a table T, is a elementary primary key that is defined with some fields belong to this table T ! Here is my test, but i get no data and cannot use the CRUD operations : In my JS file i have this lines code: ... colModel":[ {"name":"index","index":"index","label":"index"}, // <= THAT'S JUST THE INDEX OF MY TABLE {"name":"user","index":"user","label":"user","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"pwd","index":"pwd","label":"pwd","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"state","index":"state","label":"state","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY ... <= AND SO ON "url":"mygrid_crud.php", "datatype":"json", "jsonReader":{repeatitems:false}, "editurl": "mygrid_crud.php", "prmNames":{"id":"index"} // <= WHAT I NEED TO WRITE HERE ??? ... In my php file (mygrid_crud.php) : ... $grid = new jqGridEdit($conn); $query = "SELECT * FROM mytable WHERE user='$user' and pwd='$pwd' and state='$state'..."; // <= SELECT * it's ok or i need to specify all fields i need ? $grid->SelectCommand = $query; $grid->dataType = "json"; $grid->table = 'mytable'; $grid->setPrimaryKeyId('index'); // <= WHAT I NEED TO WRITE HERE ??? ... $grid->editGrid(); Please, say me what is wrong, and how to do to set a composite primary key in this approach !? Thank you so much for tour responses.

  • How should I format an HTTPService result in Flex so that it is accessible for a pie chart?

    - by Eric Reynolds
    I feel like this should be simple, however everywhere I look online someone does something different. I am doing a small charting application to track download statistics, and want to put the data into a pie chart. I am new to Flex, so if my code is horrible I apologize. <s:HTTPService id="service" url="admin/stats/totalstats.php" fault="service_faultHandler(event)" result="service_resultHandler(event)" /> What is the best resultFormat for this purpose, and if I am assigning the returned value to an ActionScript variable, should it be an ArrayList? ArrayCollection? Heres a sample of the XML being returned from the HTTPService <DownloadStats> <year count="24522" year="2008"> <month count="20" month="5" year="2008" full="May 2008"> <day count="2" month="5" day="20" year="2008"/> <day count="1" month="5" day="21" year="2008"/> <day count="9" month="5" day="22" year="2008"/> <day count="1" month="5" day="23" year="2008"/> <day count="1" month="5" day="29" year="2008"/> <day count="1" month="5" day="30" year="2008"/> <day count="5" month="5" day="31" year="2008"/> </month> ... </year> <DownloadStats> Any help is appreciated, Thanks, Eric R. EDIT: I decided that it would be helpful to see how I am transferring the data to the chart to make sure I am not doing something wrong there either. <mx:PieChart id="pieChart"> <mx:PieSeries nameField="year" field="count" labelPosition="callout" displayName="Total" dataProvider="{graphData}"/> </mx:PieChart>
