• Setting up a pc bluetooth server for android

  - by Del

  Alright, I've been reading a lot of topics the past two or three days and nothing seems to have asked this. I am writing a PC side server for my andriod device, this is for exchanging some information and general debugging. Eventually I will be connecting to a SPP device to control a microcontroller. I have managed, using the following (Android to pc) to connect to rfcomm channel 11 and exchange data between my android device and my pc. Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { int.class }); tmp = (BluetoothSocket) m.invoke(device, Integer.valueOf(11)); I have attempted the createRfcommSocketToServiceRecord(UUID) method, with absolutely no luck. For the PC side, I have been using the C Bluez stack for linux. I have the following code which registers the service and opens a server socket: int main(int argc, char **argv) { struct sockaddr_rc loc_addr = { 0 }, rem_addr = { 0 }; char buf[1024] = { 0 }; char str[1024] = { 0 }; int s, client, bytes_read; sdp_session_t *session; socklen_t opt = sizeof(rem_addr); session = register_service(); s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM); loc_addr.rc_family = AF_BLUETOOTH; loc_addr.rc_bdaddr = *BDADDR_ANY; loc_addr.rc_channel = (uint8_t) 11; bind(s, (struct sockaddr *)&loc_addr, sizeof(loc_addr)); listen(s, 1); client = accept(s, (struct sockaddr *)&rem_addr, &opt); ba2str( &rem_addr.rc_bdaddr, buf ); fprintf(stderr, "accepted connection from %s\n", buf); memset(buf, 0, sizeof(buf)); bytes_read = read(client, buf, sizeof(buf)); if( bytes_read 0 ) { printf("received [%s]\n", buf); } sprintf(str,"to Android."); printf("sent [%s]\n",str); write(client, str, sizeof(str)); close(client); close(s); sdp_close( session ); return 0; } sdp_session_t *register_service() { uint32_t svc_uuid_int[] = { 0x00000000,0x00000000,0x00000000,0x00000000 }; uint8_t rfcomm_channel = 11; const char *service_name = "Remote Host"; const char *service_dsc = "What the remote should be connecting to."; const char *service_prov = "Your mother"; uuid_t root_uuid, l2cap_uuid, rfcomm_uuid, svc_uuid; sdp_list_t *l2cap_list = 0, *rfcomm_list = 0, *root_list = 0, *proto_list = 0, *access_proto_list = 0; sdp_data_t *channel = 0, *psm = 0; sdp_record_t *record = sdp_record_alloc(); // set the general service ID sdp_uuid128_create( &svc_uuid, &svc_uuid_int ); sdp_set_service_id( record, svc_uuid ); // make the service record publicly browsable sdp_uuid16_create(&root_uuid, PUBLIC_BROWSE_GROUP); root_list = sdp_list_append(0, &root_uuid); sdp_set_browse_groups( record, root_list ); // set l2cap information sdp_uuid16_create(&l2cap_uuid, L2CAP_UUID); l2cap_list = sdp_list_append( 0, &l2cap_uuid ); proto_list = sdp_list_append( 0, l2cap_list ); // set rfcomm information sdp_uuid16_create(&rfcomm_uuid, RFCOMM_UUID); channel = sdp_data_alloc(SDP_UINT8, &rfcomm_channel); rfcomm_list = sdp_list_append( 0, &rfcomm_uuid ); sdp_list_append( rfcomm_list, channel ); sdp_list_append( proto_list, rfcomm_list ); // attach protocol information to service record access_proto_list = sdp_list_append( 0, proto_list ); sdp_set_access_protos( record, access_proto_list ); // set the name, provider, and description sdp_set_info_attr(record, service_name, service_prov, service_dsc); int err = 0; sdp_session_t *session = 0; // connect to the local SDP server, register the service record, and // disconnect session = sdp_connect( BDADDR_ANY, BDADDR_LOCAL, SDP_RETRY_IF_BUSY ); err = sdp_record_register(session, record, 0); // cleanup //sdp_data_free( channel ); sdp_list_free( l2cap_list, 0 ); sdp_list_free( rfcomm_list, 0 ); sdp_list_free( root_list, 0 ); sdp_list_free( access_proto_list, 0 ); return session; } And another piece of code, in addition to 'sdptool browse local' which can verifty that the service record is running on the pc: int main(int argc, char **argv) { uuid_t svc_uuid;

I've tried a several different UUIDs and on two different computers, although I only have my HTC Incredible to test with. I've also heard some rumors that the BT stack wasn't working on the HTC Droid, but that isn't the case, at least, for PC interaction.

• Reuse Client java Socket in a Java Server

  - by user1394983

  I'm devoloping an Java server two control an android online game. It's possible save the client socket of myserversocket.accept() in a variable in Client class? This are very util because this way, server can communicate with client when server wants and no when client contact server. My actual code are: import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.net.ServerSocket; import java.net.Socket; import java.util.ArrayList; import java.util.UUID;

• Conflict between two Javascripts (MailChimp validation etc. scripts & jQuery hSlides.js)

  - by Brian

  I have two scripts running on the same page, one is the jQuery.hSlides.js script http://www.jesuscarrera.info/demos/hslides/ and the other is a custom script that is used for MailChimp list signup integration. The hSlides panel can be seen in effect here: http://theatricalbellydance.com. I've turned off the MailChimp script because it was conflicting with the hSlides script, causing it not to to fail completely (as seen here http://theatricalbellydance.com/home2/). Can someone tell me what could be done to the hSlides script to stop the conflict with the MailChimp script?

• java inserting special characters with preparedstatement fails

  - by phill

  I am using an HTML form which sends <input type=hidden name=longdesc value='SMARTNET%^" 8X5XNBD'> this is done by the following javascript code: function masinsert(id) { var currentTime=new Date(); var button = document.getElementById("m"+id); button.onclick=""; button.value="Inserting"; var itemdescription = document.getElementById("itemdescription"+id).value; function handleHttpResponse() { if (http.readyState == 4) { button.value="Item Added"; } } var http = getHTTPObject(); // We create the HTTP Object var tempUrl = "\AInsert"; tempUrl += "itemdescription="+itemdescription+"&"+"itemshortdescription="+itemdescription.substring(0,37)+; alert(tempUrl); http.open("GET", tempUrl, true); http.onreadystatechange = handleHttpResponse; http.send(null); } to a java servlet. AInsert.java in the AInsert.java file, I do a String itemdescription = request.getParameter("longdesc"); which then sends the value to a preparedstatement to run an insert query. In the query, there are sometimes special characters which throw it off. For example, when I run the following insert into itemdescription (longdesc) values ('SMARTNET%^" 8X5XNBD') here is the actual snippet: PreparedStatement ps = conn.prepareStatement("INSERT INTO itemdescription (longdesc) values(?)"); ps.setString(1, itemdescription); ps.executeUpdate(); It will produce an error saying : Cannot insert the value NULL into column 'LongDesc', table 'App.dbo.itemdescription'; column does not allow nulls. Insert fails I have tried urlencode/urldecode String encodedString = URLEncoder.encode(longdesc, "UTF-8"); String decitemdescription = URLDecoder.decode(itemdescription, "UTF-8"); and i've also tried these functions //BEGIN URL Encoder final static String[] hex = { "%00", "%01", "%02", "%03", "%04", "%05", "%06", "%07", "%08", "%09", "%0a", "%0b", "%0c", "%0d", "%0e", "%0f", "%10", "%11", "%12", "%13", "%14", "%15", "%16", "%17", "%18", "%19", "%1a", "%1b", "%1c", "%1d", "%1e", "%1f", "%20", "%21", "%22", "%23", "%24", "%25", "%26", "%27", "%28", "%29", "%2a", "%2b", "%2c", "%2d", "%2e", "%2f", "%30", "%31", "%32", "%33", "%34", "%35", "%36", "%37", "%38", "%39", "%3a", "%3b", "%3c", "%3d", "%3e", "%3f", "%40", "%41", "%42", "%43", "%44", "%45", "%46", "%47", "%48", "%49", "%4a", "%4b", "%4c", "%4d", "%4e", "%4f", "%50", "%51", "%52", "%53", "%54", "%55", "%56", "%57", "%58", "%59", "%5a", "%5b", "%5c", "%5d", "%5e", "%5f", "%60", "%61", "%62", "%63", "%64", "%65", "%66", "%67", "%68", "%69", "%6a", "%6b", "%6c", "%6d", "%6e", "%6f", "%70", "%71", "%72", "%73", "%74", "%75", "%76", "%77", "%78", "%79", "%7a", "%7b", "%7c", "%7d", "%7e", "%7f", "%80", "%81", "%82", "%83", "%84", "%85", "%86", "%87", "%88", "%89", "%8a", "%8b", "%8c", "%8d", "%8e", "%8f", "%90", "%91", "%92", "%93", "%94", "%95", "%96", "%97", "%98", "%99", "%9a", "%9b", "%9c", "%9d", "%9e", "%9f", "%a0", "%a1", "%a2", "%a3", "%a4", "%a5", "%a6", "%a7", "%a8", "%a9", "%aa", "%ab", "%ac", "%ad", "%ae", "%af", "%b0", "%b1", "%b2", "%b3", "%b4", "%b5", "%b6", "%b7", "%b8", "%b9", "%ba", "%bb", "%bc", "%bd", "%be", "%bf", "%c0", "%c1", "%c2", "%c3", "%c4", "%c5", "%c6", "%c7", "%c8", "%c9", "%ca", "%cb", "%cc", "%cd", "%ce", "%cf", "%d0", "%d1", "%d2", "%d3", "%d4", "%d5", "%d6", "%d7", "%d8", "%d9", "%da", "%db", "%dc", "%dd", "%de", "%df", "%e0", "%e1", "%e2", "%e3", "%e4", "%e5", "%e6", "%e7", "%e8", "%e9", "%ea", "%eb", "%ec", "%ed", "%ee", "%ef", "%f0", "%f1", "%f2", "%f3", "%f4", "%f5", "%f6", "%f7", "%f8", "%f9", "%fa", "%fb", "%fc", "%fd", "%fe", "%ff" }; /** * Encode a string to the "x-www-form-urlencoded" form, enhanced * with the UTF-8-in-URL proposal.

Any ideas? thanks in advance UPDATE: I tried adding these two statements to grab the request String itemdescription = URLDecoder.decode(request.getParameter("itemdescription"), "UTF-8"); String itemshortdescription = URLDecoder.decode(request.getParameter("itemshortdescription"), "UTF-8"); System.out.println("processRequest | short descrip "); and this is failing as well if that helps. UPDATE2: I created an html form and did a direct insert with the encoded itemdescription such as and the insertion works correctly with the special charaters and everything. I guess there is something going on with my javascript submit. Any ideas on this?

• JavaFx 2.1, 2.2 TableView update issue

  - by Lewis Liu

  My application uses JPA read data into TableView then modify and display them. The table refreshed modified record under JavaFx 2.0.3. Under JavaFx 2.1, 2.2, the table wouldn't refresh the update anymore. I found other people have similar issue. My plan was to continue using 2.0.3 until someone fixes the issue under 2.1 and 2.2. Now I know it is not a bug and wouldn't be fixed. Well, I don't know how to deal with this. Following are codes are modified from sample demo to show the issue. If I add a new record or delete a old record from table, table refreshes fine. If I modify a record, the table wouldn't refreshes the change until a add, delete or sort action is taken. If I remove the modified record and add it again, table refreshes. But the modified record is put at button of table. Well, if I remove the modified record, add the same record then move the record to the original spot, the table wouldn't refresh anymore. Below is a completely code, please shine some light on this. import javafx.application.Application; import javafx.beans.property.SimpleStringProperty; import javafx.collections.FXCollections; import javafx.collections.ObservableList;

• How to Make a Game like Space Invaders - Ray Wenderlich (why do my space invaders scroll off screen)

  - by Erv Noel

  I'm following this tutorial(http://www.raywenderlich.com/51068/how-to-make-a-game-like-space-invaders-with-sprite-kit-tutorial-part-1) and I've run into a problem right after the part where I add [self determineInvaderMovementDirection]; to my GameScene.m file (specifically to my moveInvadersForUpdate method) The tutorial states that the space invaders should be moving accordingly after adding this piece of code but when I run they move to the left and they do not come back. I'm not sure what I am doing wrong as I have followed this tutorial very carefully. Any help or clarification would be greatly appreciated. Thanks in advance !

• TabHost disappears after locking the phone and reopening it:

  - by Emil Adz

  I have a weird issue with my TabHost in my FragmentActivity that contains a ViewPager. The problem is that when I close my phone (press the power button) while I use my application, and then I turn back the phone and my application gets reopened, at this point my TabHost is missing. So the closing of my phone is causes the TabHost to disappear. My guess would be that I need to save my tabHost state in the saveInstanceState object, and restore it in onResume I only have no idea how it's done. here is my code for the FragmentActivity: public class TabsViewPagerFragmentActivity extends FragmentActivity implements ViewPager.OnPageChangeListener, TabHost.OnTabChangeListener { static final String TAG = TabsViewPagerFragmentActivity.class.getSimpleName();

• Using libgrib2c in c++ application, linker error "Undefined reference to..."

  - by Rich

  EDIT: If you're going to be doing things with GRIB files I would recommend the GDAL library which is backed by the Open Source Geospatial Foundation. You will save yourself a lot of headache :) I'm using Qt creator in Ubuntu creating a c++ app. I am attempting to use an external lib, libgrib2c.a, that has a header grib2.h. Everything compiles, but when it tries to link I get the error: undefined reference to 'seekgb(_IO_FILE*, long, long, long*, long*) I have tried wrapping the header file with: extern "C"{ #include "grib2.h" } But it didn't fix anything so I figured that was not my problem. In the .pro file I have the line: include($${ROOT}/Shared/common/commonLibs.pri) and in commonLibs.pri I have: INCLUDEPATH+=$${ROOT}/external_libs/g2clib/include LIBS+=-L$${ROOT}/external_libs/g2clib/lib LIBS+=-lgrib2c I am not encountering an error finding the library. If I do a nm command on the libgrib2c.a I get: nm libgrib2c.a | grep seekgb seekgb.o: 00000000 T seekgb And when I run qmake with the additional argument of LIBS+=-Wl,--verbose I can find the lib file in the output: attempt to open /usr/lib/libgrib2c.so failed attempt to open /usr/lib/libgrib2c.a failed attempt to open /mnt/sdb1/ESMF/App/ESMF_App/../external_libs/linux/qwt_6.0.2/lib/libgrib2c.so failed attempt to open /mnt/sdb1/ESMF/App/ESMF_App/../external_libs/linux/qwt_6.0.2/lib/libgrib2c.a failed attempt to open ..//Shared/Config/lib/libgrib2c.so failed attempt to open ..//Shared/Config/lib/libgrib2c.a failed attempt to open ..//external_libs/libssh2/lib/libgrib2c.so failed attempt to open ..//external_libs/libssh2/lib/libgrib2c.a failed attempt to open ..//external_libs/openssl/lib/libgrib2c.so failed attempt to open ..//external_libs/openssl/lib/libgrib2c.a failed attempt to open ..//external_libs/g2clib/lib/libgrib2c.so failed attempt to open ..//external_libs/g2clib/lib/libgrib2c.a succeeded Although it doesn't show any of the .o files in the library is this because it is a c library in my c++ app? in the .cpp file that I am trying to use the library I have: #include "gribreader.h" #include <stdio.h> #include <stdlib.h> #include <external_libs/g2clib/include/grib2.h> #include <Shared/logging/Logger.hpp> //------------------------------------------------------------------------------ /// Opens a GRIB file from disk. /// /// This function opens the grib file and searches through it for how many GRIB /// messages are contained as well as their starting locations. /// /// \param a_filePath.

If anyone has an idea on what to do or can point me in some sort of direction, I'm stumped. Also, if you have any comments on how I can improve this post I'd love to hear them, kinda new at this posting thing. Usually I'm able to find an answer in the vast stores of knowledge already contained on the web.

• Dividing web.config into multiple files in asp.net

  - by Jalpesh P. Vadgama

  When you are having different people working on one project remotely you will get some problem with web.config, as everybody was having different version of web.config. So at that time once you check in your web.config with your latest changes the other people have to get latest that web.config and made some specific changes as per their local environment. Most of people who have worked things from remotely has faced that problem. I think most common example would be connection string and app settings changes. For this kind of situation this will be a best solution. We can divide particular section of web.config into the multiple files. For example we could have separate ConnectionStrings.config file for connection strings and AppSettings.config file for app settings file. Most of people does not know that there is attribute called ‘configSource’ where we can  define the path of external config file and it will load that section from that external file. Just like below. <configuration> <appSettings configSource="AppSettings.config"/> <connectionStrings configSource="ConnectionStrings.config"/> </configuration> And you could have your ConnectionStrings.config file like following. <connectionStrings> <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-WebApplication1-20120523114732;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings> Same way you have another AppSettings.Config file like following. <appSettings> <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> <add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" /> </appSettings> That's it. Hope you like this post. Stay tuned for more..

• Using JCA Adapter with OSB 11.1.1.3

  - by James Taylor

  In OSB 10g to use the JCA adapters you were required to use JDeveloper to create the necessary WSDLs and XSDs etc using the associated adapter wizard. These files were imported into Oracle Workshop (Eclipse) and used to create the business service as you would any other web service. In 11g unfortunately JDeveloper is still required. The process has changed slightly as described below. As an example I have used the JCA DB adapter as an example. Start JDeveloper 11.1.1.3 Create a new SOA Application Create a new SOA Project and call it DBAdapters. Choose the Empty Composite Template Drag a Database Adapter Component to the External References panel on the composite. Provide a service name. Create a new database connection, or use an existing one Take note of the JNDI Name, e.g. eis/DB/MyConnection This will be used to configure the DB connection in the WebLogic Console. In my example I use a stored procedure, but you can use what ever operation you require. Please refer to the following link for other options: User's Guide for Technology Adapters Select a schema and stored procedure Once the procedure has been selected, accept the defaults and finish. Startup your OEPE version of Eclipse. Create a new Oracle Service Bus Configuration Project (you can use an existing project if you have one) Create a new Oracle Service Bus Project in the configuration project created above. Instead of importing the WSDL and XSD files you import the jca file created in JDeveloper. In Eclipse right click the Oracle Service Bus Project and select Import –> Import    Choose File System Browse to the directory where JDeveloper stores its project Select the jca, wsdl, and xsd files based on the service you created in step 5. Also check the ‘Create selected folders only’ radio button. When you import you may have a little red x indicating the files are invalid. This is due to the location of the files. Open the invalid files and fix the path in relation to where you store your files in the OSB project.   Once you have the files all valid, Right-Click the jca file and select Oracle Service Bus –> Generate Service. This will create a new Business Service. In the WebLogic Console configure the JNDI name defined in step 7. You can now deploy your project and test

• Umbraco Permissions Script - Secure Version

  - by Vizioz Limited

  Back in May I blogged about how to set Permissions for Umbraco using SetACL to set the appropriate directory permissions based on the installation recommendations.Recently I have been working on a site for a client who wanted every security item to be locked down as tightly as possible. And so I modified the script based on the Umbraco security best practices, I thought I'd share it with everyone, if I have missed anything, or if anyone has any suggestions on how to improve this, please let me know :)Please refer to my previous post regarding the SetAcl command line application that you will need.I suggest you save the following into a batch file called: umbPermSecure.batecho offREM Script to setup the Security Permissions for an Umbraco siteREM This script will give your machine Network Service the minimum rights requiredREM for Umbraco to workREM I suggest you update this script to also remove any users who do not need REM access to the web foldersREM **** Pre-requisites ****REM You will need to download - http://setacl.sourceforge.net/REM It is assumed that you have stored SetACL in a directory called, C:\SetACL ifREM not, you will need to modify the script.REM **** Usage ****REM You need to pass in the path for the root of your Umbraco directoryREM E.g. umbPermSecure.bat C:\inetpub\umbracoroot@echo umbPermSecure.bat - Script to set Umbraco File and Directory Permissions@echo based on the Umbraco Security Best Practices Document (13th March 2009)@echo Published by Chris Houston - 19th October 2009@echo http://blog.vizioz.com@echo Adding READ only access SetACL.exe -on "%1" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\web.config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\bin" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\umbraco" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ and EXECUTE access SetACL.exe -on "%1\app_code" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\usercontrols" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read_ex" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"@echo Adding READ, WRITE and MODIFY access SetACL.exe -on "%1\config" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\css" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\data" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\masterpages" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\media" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\python" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\scripts" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"SetACL.exe -on "%1\xslt" -ot file -actn ace -ace "n:%computername%\NETWORK SERVICE;p:read" -ace "n:%computername%\NETWORK SERVICE;p:change" -actn clear -clr "dacl,sacl" -log "c:\setacl\log.txt"

• Windows and SQL Azure Best Practices: Affinity Groups

  - by BuckWoody

  When you create a Windows Azure application, you’ll pick a subscription to put it under. This is a billing container - underneath that, you’ll deploy a Hosted Service. That holds the Web and Worker Roles that you’ll deploy for your applications. along side that, you use the Storage Account to create storage for the application. (In some cases, you might choose to use only storage or Roles - the info here applies anyway) As you are setting up your environment, you’re asked to pick a “region” where your application will run. If you choose a Region, you’ll be asked where to put the Roles. You’re given choices like Asia, North America and so on. This is where the hardware that physically runs your code lives. We have lots of fault domains, power considerations and so on to keep that set of datacenters running, but keep in mind that this is where the application lives. You also get this selection for Storage Accounts. When you make new storage, it’s a best practice to put it where your computing is. This makes the shortest path from the code to the data, and then back out to the user. One of the selections for the location is “Anywhere U.S.”. This selection might be interpreted to mean that we will bias towards keeping the data and the code together, but that may not be the case. There is a specific abstraction we created for just that purpose: Affinity Groups. An Affinity Group is simply a name you can use to tie together resources. You can do this in two places - when you’re creating the Hosted Service (shown above) and on it’s own tree item on the left, called “Affinity Groups”. When you select either of those actions, You’re presented with a dialog box that allows you to specify a name, and then the Region that  names ties the resources to. Now you can select that Affinity Group just as if it were a Region, and your code and data will stay together. That helps with keeping the performance high.

• Metro: Using Templates

  - by Stephen.Walther

  The goal of this blog post is to describe how templates work in the WinJS library. In particular, you learn how to use a template to display both a single item and an array of items. You also learn how to load a template from an external file. Why use Templates? Imagine that you want to display a list of products in a page. The following code is bad: var products = [ { name: "Tesla", price: 80000 }, { name: "VW Rabbit", price: 200 }, { name: "BMW", price: 60000 } ]; var productsHTML = ""; for (var i = 0; i < products.length; i++) { productsHTML += "<h1>Product Details</h1>" + "<div>Product Name: " + products[i].name + "</div>" + "<div>Product Price: " + products[i].price + "</div>"; } document.getElementById("productContainer").innerHTML = productsHTML; In the code above, an array of products is displayed by creating a for..next loop which loops through each element in the array. A string which represents a list of products is built through concatenation. The code above is a designer’s nightmare. You cannot modify the appearance of the list of products without modifying the JavaScript code. A much better approach is to use a template like this: <div id="productTemplate"> <h1>Product Details</h1> <div> Product Name: <span data-win-bind="innerText:name"></span> </div> <div> Product Price: <span data-win-bind="innerText:price"></span> </div> </div> A template is simply a fragment of HTML that contains placeholders. Instead of displaying a list of products by concatenating together a string, you can render a template for each product. Creating a Simple Template Let’s start by using a template to render a single product. The following HTML page contains a template and a placeholder for rendering the template: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Application1</title> <!-- WinJS references --> <link href="//Microsoft.WinJS.0.6/css/ui-dark.css" rel="stylesheet"> <script src="//Microsoft.WinJS.0.6/js/base.js"></script> <script src="//Microsoft.WinJS.0.6/js/ui.js"></script> <!-- Application1 references --> <link href="/css/default.css" rel="stylesheet"> <script src="/js/default.js"></script> </head> <body> <!-- Product Template --> <div id="productTemplate"> <h1>Product Details</h1> <div> Product Name: <span data-win-bind="innerText:name"></span> </div> <div> Product Price: <span data-win-bind="innerText:price"></span> </div> </div> <!-- Place where Product Template is Rendered --> <div id="productContainer"></div> </body> </html> In the page above, the template is defined in a DIV element with the id productTemplate. The contents of the productTemplate are not displayed when the page is opened in the browser. The contents of a template are automatically hidden when you convert the productTemplate into a template in your JavaScript code. Notice that the template uses data-win-bind attributes to display the product name and price properties. You can use both data-win-bind and data-win-bindsource attributes within a template. To learn more about these attributes, see my earlier blog post on WinJS data binding: http://stephenwalther.com/blog/archive/2012/02/26/windows-web-applications-declarative-data-binding.aspx The page above also includes a DIV element named productContainer. The rendered template is added to this element. Here’s the code for the default.js script which creates and renders the template: (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { var product = { name: "Tesla", price: 80000 }; var productTemplate = new WinJS.Binding.Template(document.getElementById("productTemplate")); productTemplate.render(product, document.getElementById("productContainer")); } }; app.start(); })(); In the code above, a single product object is created with the following line of code: var product = { name: "Tesla", price: 80000 }; Next, the productTemplate element from the page is converted into an actual WinJS template with the following line of code: var productTemplate = new WinJS.Binding.Template(document.getElementById("productTemplate")); The template is rendered to the templateContainer element with the following line of code: productTemplate.render(product, document.getElementById("productContainer")); The result of this work is that the product details are displayed: Notice that you do not need to call WinJS.Binding.processAll(). The Template render() method takes care of the binding for you. Displaying an Array in a Template If you want to display an array of products using a template then you simply need to create a for..next loop and iterate through the array calling the Template render() method for each element. (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { var products = [ { name: "Tesla", price: 80000 }, { name: "VW Rabbit", price: 200 }, { name: "BMW", price: 60000 } ]; var productTemplate = new WinJS.Binding.Template(document.getElementById("productTemplate")); var productContainer = document.getElementById("productContainer"); var i, product; for (i = 0; i < products.length; i++) { product = products[i]; productTemplate.render(product, productContainer); } } }; app.start(); })(); After each product in the array is rendered with the template, the result is appended to the productContainer element. No changes need to be made to the HTML page discussed in the previous section to display an array of products instead of a single product. The same product template can be used in both scenarios. Rendering an HTML TABLE with a Template When using the WinJS library, you create a template by creating an HTML element in your page. One drawback to this approach of creating templates is that your templates are part of your HTML page. In order for your HTML page to validate, the HTML within your templates must also validate. This means, for example, that you cannot enclose a single HTML table row within a template. The following HTML is invalid because you cannot place a TR element directly within the body of an HTML document:   <!-- Product Template --> <tr> <td data-win-bind="innerText:name"></td> <td data-win-bind="innerText:price"></td> </tr> This template won’t validate because, in a valid HTML5 document, a TR element must appear within a THEAD or TBODY element. Instead, you must create the entire TABLE element in the template. The following HTML page illustrates how you can create a template which contains a TR element: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Application1</title> <!-- WinJS references --> <link href="//Microsoft.WinJS.0.6/css/ui-dark.css" rel="stylesheet"> <script src="//Microsoft.WinJS.0.6/js/base.js"></script> <script src="//Microsoft.WinJS.0.6/js/ui.js"></script> <!-- Application1 references --> <link href="/css/default.css" rel="stylesheet"> <script src="/js/default.js"></script> </head> <body> <!-- Product Template --> <div id="productTemplate"> <table> <tbody> <tr> <td data-win-bind="innerText:name"></td> <td data-win-bind="innerText:price"></td> </tr> </tbody> </table> </div> <!-- Place where Product Template is Rendered --> <table> <thead> <tr> <th>Name</th><th>Price</th> </tr> </thead> <tbody id="productContainer"> </tbody> </table> </body> </html>   In the HTML page above, the product template includes TABLE and TBODY elements: <!-- Product Template --> <div id="productTemplate"> <table> <tbody> <tr> <td data-win-bind="innerText:name"></td> <td data-win-bind="innerText:price"></td> </tr> </tbody> </table> </div> We discard these elements when we render the template. The only reason that we include the TABLE and THEAD elements in the template is to make the HTML page validate as valid HTML5 markup. Notice that the productContainer (the target of the template) in the page above is a TBODY element. We want to add the rows rendered by the template to the TBODY element in the page. The productTemplate is rendered in the default.js file: (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { var products = [ { name: "Tesla", price: 80000 }, { name: "VW Rabbit", price: 200 }, { name: "BMW", price: 60000 } ]; var productTemplate = new WinJS.Binding.Template(document.getElementById("productTemplate")); var productContainer = document.getElementById("productContainer"); var i, product, row; for (i = 0; i < products.length; i++) { product = products[i]; productTemplate.render(product).then(function (result) { row = WinJS.Utilities.query("tr", result).get(0); productContainer.appendChild(row); }); } } }; app.start(); })(); When the product template is rendered, the TR element is extracted from the rendered template by using the WinJS.Utilities.query() method. Next, only the TR element is added to the productContainer: productTemplate.render(product).then(function (result) { row = WinJS.Utilities.query("tr", result).get(0); productContainer.appendChild(row); }); I discuss the WinJS.Utilities.query() method in depth in a previous blog entry: http://stephenwalther.com/blog/archive/2012/02/23/windows-web-applications-query-selectors.aspx When everything gets rendered, the products are displayed in an HTML table: You can see the actual HTML rendered by looking at the Visual Studio DOM Explorer window:   Loading an External Template Instead of embedding a template in an HTML page, you can place your template in an external HTML file. It makes sense to create a template in an external file when you need to use the same template in multiple pages. For example, you might need to use the same product template in multiple pages in your application. The following HTML page does not contain a template. It only contains a container that will act as a target for the rendered template: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Application1</title> <!-- WinJS references --> <link href="//Microsoft.WinJS.0.6/css/ui-dark.css" rel="stylesheet"> <script src="//Microsoft.WinJS.0.6/js/base.js"></script> <script src="//Microsoft.WinJS.0.6/js/ui.js"></script> <!-- Application1 references --> <link href="/css/default.css" rel="stylesheet"> <script src="/js/default.js"></script> </head> <body> <!-- Place where Product Template is Rendered --> <div id="productContainer"></div> </body> </html> The template is contained in a separate file located at the path /templates/productTemplate.html:   Here’s the contents of the productTemplate.html file: <!-- Product Template --> <div id="productTemplate"> <h1>Product Details</h1> <div> Product Name: <span data-win-bind="innerText:name"></span> </div> <div> Product Price: <span data-win-bind="innerText:price"></span> </div> </div> Notice that the template file only contains the template and not the standard opening and closing HTML elements. It is an HTML fragment. If you prefer, you can include all of the standard opening and closing HTML elements in your external template – these elements get stripped away automatically: <html> <head><title>product template</title></head> <body> <!-- Product Template --> <div id="productTemplate"> <h1>Product Details</h1> <div> Product Name: <span data-win-bind="innerText:name"></span> </div> <div> Product Price: <span data-win-bind="innerText:price"></span> </div> </div> </body> </html> Either approach – using a fragment or using a full HTML document  — works fine. Finally, the following default.js file loads the external template, renders the template for each product, and appends the result to the product container: (function () { "use strict"; var app = WinJS.Application; app.onactivated = function (eventObject) { if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) { var products = [ { name: "Tesla", price: 80000 }, { name: "VW Rabbit", price: 200 }, { name: "BMW", price: 60000 } ]; var productTemplate = new WinJS.Binding.Template(null, { href: "/templates/productTemplate.html" }); var productContainer = document.getElementById("productContainer"); var i, product, row; for (i = 0; i < products.length; i++) { product = products[i]; productTemplate.render(product, productContainer); } } }; app.start(); })(); The path to the external template is passed to the constructor for the Template class as one of the options: var productTemplate = new WinJS.Binding.Template(null, {href:"/templates/productTemplate.html"}); When a template is contained in a page then you use the first parameter of the WinJS.Binding.Template constructor to represent the template – instead of null, you pass the element which contains the template. When a template is located in an external file, you pass the href for the file as part of the second parameter for the WinJS.Binding.Template constructor. Summary The goal of this blog entry was to describe how you can use WinJS templates to render either a single item or an array of items to a page. We also explored two advanced topics. You learned how to render an HTML table by extracting the TR element from a template. You also learned how to place a template in an external file.

  Quick Links Live Demo Source Code I finally got a live demo up and running!  I signed up for a shared hosting account over at discountasp.net so I could post a working version of the Earthquake Locator application, but ran into a few minor issues related to RIA Services.  Thankfully, Tim Heuer had already encountered and explained all of the problems I had along with solutions to these and other common pitfalls.  You can find his blog post here.  The ones that got me were the default authentication tag being set to Windows instead of Forms, needed to add the <baseAddressPrefixFilters> tag since I was running on a shared server using host headers, and finally the Multiple Authentication Schemes settings in the IIS7 Manager.   To get the demo application ready, I pulled down local copies of the earthquake data feeds that the application can use instead of pulling from the USGS web site.  I basically added the feed URL as an app setting in the web.config:       <appSettings>         <!-- USGS Data Feeds: http://earthquake.usgs.gov/earthquakes/catalogs/ -->         <!--<add key="FeedUrl"             value="http://earthquake.usgs.gov/earthquakes/catalogs/1day-M2.5.xml" />-->         <!--<add key="FeedUrl"             value="http://earthquake.usgs.gov/earthquakes/catalogs/7day-M2.5.xml" />-->         <!--<add key="FeedUrl"             value="~/Demo/1day-M2.5.xml" />-->         <add key="FeedUrl"              value="~/Demo/7day-M2.5.xml" />     </appSettings> You will need to do the same if you want to run from local copies of the feed data.  I also made the following minor changes to the EarthquakeService class so that it gets the FeedUrl from the web.config:       private static readonly string FeedUrl = ConfigurationManager.AppSettings["FeedUrl"];       /// <summary>     /// Gets the feed at the specified URL.     /// </summary>     /// <param name="url">The URL.</param>     /// <returns>A <see cref="SyndicationFeed"/> object.</returns>     public static SyndicationFeed GetFeed(String url)     {         SyndicationFeed feed = null;           if ( !String.IsNullOrEmpty(url) && url.StartsWith("~") )         {             // resolve virtual path to physical file system             url = System.Web.HttpContext.Current.Server.MapPath(url);         }           try         {             log.Debug("Loading RSS feed: " + url);               using ( var reader = XmlReader.Create(url) )             {                 feed = SyndicationFeed.Load(reader);             }         }         catch ( Exception ex )         {             log.Error("Error occurred while loading RSS feed: " + url, ex);         }           return feed;     } You can now view the live demo or download the source code here, but be sure you have WCF RIA Services installed before running the application locally and make sure the FeedUrl is pointing to a valid location.  Please let me know if you have any comments or if you run into any issues with the code.   Enjoy!

• DevConnections jQuery Session Slides and Samples posted

  - by Rick Strahl

  I’ve posted all of my slides and samples from the DevConnections VS 2010 Launch event last week in Vegas. All three sessions are contained in a single zip file which contains all slide decks and samples in one place: www.west-wind.com/files/conferences/jquery.zip There were 3 separate sessions: Using jQuery with ASP.NET Starting with an overview of jQuery client features via many short and fun examples, you'll find out about core features like the power of selectors to select document elements, manipulate these elements with jQuery's wrapped set methods in a browser independent way, how to hook up and handle events easily and generally apply concepts of unobtrusive JavaScript principles to client scripting. The session also covers AJAX interaction between jQuery and the .NET server side code using several different approaches including sending HTML and JSON data and how to avoid user interface duplication by using client side templating. This session relies heavily on live examples and walk-throughs. jQuery Extensibility and Integration with ASP.NET Server Controls One of the great strengths of the jQuery Javascript framework is its simple, yet powerful extensibility model that has resulted in an explosion of plug-ins available for jQuery. You need it - chances are there's a plug-in for it! In this session we'll look at a few plug-ins to demonstrate the power of the jQuery plug-in model before diving in and creating our own custom jQuery plug-ins. We'll look at how to create a plug-in from scratch as well as discussing when it makes sense to do so. Once you have a plug-in it can also be useful to integrate it more seamlessly with ASP.NET by creating server controls that coordinate both server side and jQuery client side behavior. I'll demonstrate a host of custom components that utilize a combination of client side jQuery functionality and server side ASP.NET server controls that provide smooth integration in the user interface development process. This topic focuses on component development both for pure client side plug-ins and mixed mode controls. jQuery Tips and Tricks This session was kind of a last minute substitution for an ASP.NET AJAX talk. Nothing too radical here :-), but I focused on things that have been most productive for myself. Look at the slide deck for individual points and some of the specific samples.   It was interesting to see that unlike in previous conferences this time around all the session were fairly packed – interest in jQuery is definitely getting more pronounced especially with microsoft’s recent announcement of focusing on jQuery integration rather than continuing on the path of ASP.NET AJAX – which is a welcome change. Most of the samples also use the West Wind Web & Ajax Toolkit and the support tools contained within it – a snapshot version of the toolkit is included in the samples download. Specicifically a number of the samples use functionality in the ww.jquery.js support file which contains a fairly large set of plug-ins and helper functionality – most of these pieces while contained in the single file are self-contained and can be lifted out of this file (several people asked). Hopefully you'll find something useful in these slides and samples.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  jQuery

• Multiple file upload with asp.net 4.5 and Visual Studio 2012

  - by Jalpesh P. Vadgama

  This post will be part of Visual Studio 2012 feature series. In earlier version of ASP.NET there is no way to upload multiple files at same time. We need to use third party control or we need to create custom control for that. But with asp.net 4.5 now its possible to upload multiple file with file upload control. With ASP.NET 4.5 version Microsoft has enhanced file upload control to support HTML5 multiple attribute. There is a property called ‘AllowedMultiple’ to support that attribute and with that you can easily upload the file. So what we are waiting for!! It’s time to create one example. On the default.aspx file I have written following. <asp:FileUpload ID="multipleFile" runat="server" AllowMultiple="true" /> <asp:Button ID="uploadFile" runat="server" Text="Upload files" onclick="uploadFile_Click"/> Here you can see that I have given file upload control id as multipleFile and I have set AllowMultiple file to true. I have also taken one button for uploading file.For this example I am going to upload file in images folder. As you can see I have also attached event handler for button’s click event. So it’s time to write server side code for this. Following code is for the server side. protected void uploadFile_Click(object sender, EventArgs e) { if (multipleFile.HasFiles) { foreach(HttpPostedFile uploadedFile in multipleFile.PostedFiles) { uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),uploadedFile.FileName)); Response.Write("File uploaded successfully"); } } } Here in the above code you can see that I have checked whether multiple file upload control has multiple files or not and then I have save that in Images folder of web application. Once you run the application in browser it will look like following. I have selected two files. Once I have selected and clicked on upload file button it will give message like following. As you can see now it has successfully upload file and you can see in windows explorer like following. As you can see it’s very easy to upload multiple file in ASP.NET 4.5. Stay tuned for more. Till then happy programming. P.S.: This feature is only supported in browser who support HTML5 multiple file upload. For other browsers it will work like normal file upload control in asp.net.
