• How can I pass FormsAuthentication.SetAuthCookie from Data Access Layer Class to WebService to Javas

  - by Reaction21

  I am using DotNetOpenAuth in my ASP.Net Website. I have modified it to work with Facebook Connect as well, using the same methods and database structures. Now I have come across a problem. I have added a Facebook Connect button to a login page. From that HTML button, I have to somehow pull information from the Facebook Connect connection and pass it into a method to authenticate the user. The way I am currently doing this is by: Calling a Javascript Function on the onlogin function of the FBML/HTML Facebook Connect button. The javascript function calls a Web service to login, which it does correctly. The web service calls my data access layer to login. And here is the problem: FormsAuthentication.SetAuthCookie is set at the data access layer. The Cookie is beyond the scope of the user's page and therefore is not set in the browser. This means that the user is authenticated, but the user's browser is never notified. So, I need to figure out if this is a bad way of doing what I need or if there is a better way to accomplish what I need. I am just not sure and have been trying to find answers for hours. Any help you have would be great.

• Why is WMDC/ActiveSync so flaky?

  - by Ira Rainey

  I'm developing a Windows Mobile app using the .NET Compact Framework 3.5 and VS2008, and for debugging using the Device Emulator V3, on Win7, and seem to have constant problems with Windows Mobile Device Centre (6.1) connecting. Using the Emulator Manager (9.0.21022.8) I cradle the device using DMA in WMDC. The problem is it's so flaky at actually connecting that it's becoming a pain. I find that when I turn my computer on, before I can get it to connect I have to open up WMDC, disable Connect over DMA, close WMDC down, reopen it again, and then it might cradle. Often I have to do this twice before it will cradle. Once it's cradled it's generally fine, but nothing seems consistent in getting it to connect. Connecting with physical devices is often better, although not always. If I plug a PDA into a USB socket other than the one it was originally plugged into then it won't connect at all. Often the best/most reliable connection method seems to be over Bluetooth, but that's quite slow. Anybody got any tips or advice?

• Using GKPeerPickerController within a selector from a Cocos2D CCMenuItem

  - by Mark Hazlett

  Hey everyone, So i'm trying to use GameKit along with Cocos2D so that when a user clicks on the multiplayer menu item it will display the GKPeerPickerController. I'm however, running into some snags. It doesn't seem to want to compile. However, it doesn't give me an error inside of the code that's in my selector. Anyways here's the code... @implementation GameOverLayer - (id) init { self = [super init]; if (self != nil) { [CCMenuItemFont setFontSize:20]; [CCMenuItemFont setFontName:@"Helvetica"]; CCMenuItem *start = [CCMenuItemFont itemFromString:@"Play Again!" target:self selector:@selector(startGame:)]; CCMenuItem *connect = [CCMenuItemFont itemFromString:@"Multiplayer" target:self selector:@selector(connect:)]; CCMenu *menu = [CCMenu menuWithItems:start,connect, nil]; [menu alignItemsVertically]; [self addChild:menu]; } return self; } -(void)startGame: (id)sender { [[CCDirector sharedDirector] replaceScene: [HelloWorld scene]]; } -(void)connect: (id)sender { GKPeerPickerController *peerPicker; peerPicker = [[GKPeerPickerController alloc] init]; peerPicker.delegate = self; peerPicker.connectionTypesMask = GKPeerPickerConnectionTypeOnline | GKPeerPickerConnectionTypeNearby; [peerPicker show]; } @end The error message i'm getting is... ".obj_class_name_GKPeerPickerController", referenced from: Literal-Pointer@_OBJC@_cls_refs@GKPeerPickerController in GameOverScene.o Symbol(s) not found Collect2: id returned 1 exit status Any ideas?

• Client unable to authenticate when connecting to WCF service

  - by davecoulter

  I have a WCF service hosted in a Windows service. The application is an intranet app, and I have programmatically set the bindings on both the service and the client as: NetTcpBinding aBinding = new NetTcpBinding(SecurityMode.Transport); aBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; aBinding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign; Both the service and client have endpoints configured with SPNs: EndpointAddress = new EndpointAddress(uri, EndpointIdentity.CreateSpnIdentity("Service1")); As far as I know, I have setup the bindings correctly-- and I am usually able to connect to the service just fine. I did however run into a case where on a server running Windows Server 2003 R2, x64, SP2 I get the following exception immediately when the client tries to connect: INNEREXCEPTION -- Exception Message: InvalidCredentialException: Either the target name is incorrect or the server has rejected the client credentials. Stack Trace: at System.Net.Security.NegoState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.NegotiateStream.AuthenticateAsClient(NetworkCredential credential, String targetName, ProtectionLevel requiredProtectionLevel, TokenImpersonationLevel allowedImpersonationLevel) at System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.OnInitiateUpgrade(Stream stream, SecurityMessageProperty& remoteSecurity) I get the exception when I try to connect to the service from another machine in the domain, but if I connect to the service on the same machine running the service it works fine. The hosting service itself is running as a domain user account-- but I have tried running the service as a Local System and Network Service to no avail. I have checked the Local Security Policies for the server and didn't see anything amiss (i.e. 'Access this computer from the network' includes 'Everyone'). Anyone have an idea of what could resolve this? I am wondering if I need to do something in Active Directory with respect to the service's SPN? I have read some about using setspn.exe to register or refresh SPNs, but I haven't needed to do this before. Why would this be working with other configurations but not the one above?

• JAAS and WebLogic 10.3: Granting specific codebase permissions to a JAR bundled within an EAR

  - by Jason

  Here's my scenario: I have a JAR within the APP-INF/lib of my EAR, to be deployed within WebLogic 10g Release 3 against which I wish to grant specific permissions. e.g., grant codebase "file:/c:/somedir/my.jar" { permission java.net.SocketPermission "*:-","accept,connect,listen, resolve"; permission java.net.SocketPermission "localhost:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "127.0.0.1:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "230.0.0.1:-","accept,connect,listen,resolve"; permission java.util.PropertyPermission "*", "read,write"; permission java.lang.RuntimePermission "*"; permission java.io.FilePermission "<<ALL FILES>>","read,write,delete"; permission javax.security.auth.AuthPermission "*"; permission java.security.SecurityPermission "*"; }; Questions: Where is the best place to define this grant - in the java.policy of the JRE, WL server's weblogic.policy, or within a XML packaged within the EAR How do I define the codebase URL to the JAR? The examples I have seen have an explicit reference to the JAR on the file system, however I am deploying the JAR packaged up within an EAR. Thanks!

• Qt Jambi: Accessing the content of QNetworkReply

  - by Richard

  Hi All, I'm having trouble accessing the content of QNetworkReply objects. Content appears to be empty or zero. According to the docs (translating from c++ to java) I think I've got this set up correctly, but to no avail. Additionally an "Unknown error" is being reported. Any ideas much appreciated. Code: public class Test extends QObject { private QWebPage page; public Test() { page = new QWebPage(); QNetworkAccessManager nac = new QNetworkAccessManager(); nac.finished.connect(this, "requestFinished(QNetworkReply)"); page.setNetworkAccessManager(nac); page.loadProgress.connect(this, "loadProgress(int)"); page.loadFinished.connect(this, "loadFinished()"); } public void requestFinished(QNetworkReply reply) { reply.reset(); reply.open(OpenModeFlag.ReadOnly); reply.readyRead.connect(this, "ready()"); // never gets called System.out.println("bytes: " + reply.url().toString()); // writes out asset uri no problem System.out.println("bytes: " + reply.bytesToWrite()); // 0 System.out.println("At end: " + reply.atEnd()); // true System.out.println("Error: " + reply.errorString()); // "Unknown error" } public void loadProgress(int progress) { System.out.println("Loaded " + progress + "%"); } public void loadFinished() { System.out.println("Done"); } public void ready() { System.out.println("Ready"); } public void open(String url) { page.mainFrame().load(new QUrl(url)); } public static void main(String[] args) { QApplication.initialize(new String[] { }); Test t = new Test(); t.open("http://news.bbc.co.uk"); QApplication.exec(); } }

• Worklight client-side API to overrideBackButton doesn't work

  - by user2503429

  I want to make something happen when back button is pressed so I put this code in Myhtml.js file : function wlCommonInit(){ /* * Application is started in offline mode as defined by a connectOnStartup property in initOptions.js file. * In order to begin communicating with Worklight Server you need to either: * * 1. Change connectOnStartup property in initOptions.js to true. * This will make Worklight framework automatically attempt to connect to Worklight Server as a part of application start-up. * Keep in mind - this may increase application start-up time. * * 2. Use WL.Client.connect() API once connectivity to a Worklight Server is required. * This API needs to be called only once, before any other WL.Client methods that communicate with the Worklight Server. * Don't forget to specify and implement onSuccess and onFailure callback functions for WL.Client.connect(), e.g: * * WL.Client.connect({ * onSuccess: onConnectSuccess, * onFailure: onConnectFailure * }); * */ // Common initialization code goes here } WL.App.overrideBackButton(backFunc); function backFunc(){ alert('You will back to previous page'); } but after build and deploy the app and I running it, nothing happened after I pressed back button, anybody have the solution ?

• How do I fix a broken connection to DB2 from a web application?

  - by Eddie White

  I support some old web applications, VBScript-based ASP for the UI and VB6 COM modules for the business and data access layers. Last weekend, I installed DB2 Connect Enterprise Edition v8 fixpack 14 on several Windows 2000 servers, and one of the web apps errors out on null data when it calls the built in VBScript function FormatNumber. This numeric data is retrieved by a SQL Server query, but the only way the SQL Server column is populated is with the calculated results returned from a DB2 query earlier in a progression through several pages. When I installed DB2 Connect EE, one of the components loaded was MDAC 2.7. I followed corporate instructions and had the installation save an ODBC System Data Source, which reported a good connection when I tested it after the install. For what it's worth, the project references in the production VB6 modules pointed to MDAC 2.5. I have tried recompiling and deploying to COM on my test server new versions of the VB6 modules referencing MDAC 2.7. My development environment is Windows XP Pro, with MDAC 2.8 and DB2 Connect EE v9.5 installed. When I deployed the updated VB6 dlls, the CreateObject fails to instantiate the classes with the error message that "The class does not support automation or the requested interface". I've rolled the DB2 Connect install back and have reinstall v8 of the DB2 runtime client, which was the previous environment. The problem, however, persists.

• server/ client server connection

  - by user312054

  I have a server side program that creates a listening server side socket. The problem occurring is that it seems as if the client side sends a connect request it gets rejected if the server side socket is listening but connects if the server side program is not running. I can see the server side program getting the client request when debugging. It seems as if the client cannot connect to a listening socket. Any suggestions on a resolution? The server side accept code snippet is this. void CSocketListen::OnAccept(int nErrorCode) { CSocket::OnAccept(nErrorCode); CSocketServer* SocketPtr = new CSocketServer(); if (Accept(*SocketPtr)) { // add to list of client sockets connected } else { delete SocketPtr; } The client side code connect is like this. SOCKET cellModem; sockaddr_in handHeld; handHeld.sin_family = AF_INET; //Address family handHeld.sin_addr.s_addr = inet_addr("127.0.0.1"); handHeld.sin_port = htons((u_short)1113); //port to use cellModem=socket(AF_INET,SOCK_STREAM,0); if(cellModem == INVALID_SOCKET) { // log socket failure return false; } else { // log socket success } if (connect(cellModem,(const struct sockaddr*)&handHeld, sizeof(handHeld)) != 0 ) { // log socket connection success } else { // log socket connection failure closesocket(cellModem); }

• Import-Pssession is not importing cmdlets when used in a custom module

  - by Douglas Plumley

  I have a PowerShell script/function that works great when I use it in my PowerShell profile or manually copy/paste the function in the PowerShell window. I'm trying to make the function accessible to other members of my team as a module. I want to have the module stored in a central place so we can all add it to our PSModulePath. Here is a copy of the basic function: Function Connect-O365{ $o365cred = Get-Credential [email protected] $session365 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $o365cred -Authentication Basic -AllowRedirection Import-PSSession $session365 -AllowClobber } If I save this function in my PowerShell profile it works fine. I can dot source a *.ps1 script with this function in it and it works as well. The issue is when I save the function as a *.psm1 PowerShell script module. The function runs fine but none of the exported commands from the Import-PSSession are available. I think this may have something to do with the module scope. I'm looking for suggestions on how to get around this. EDIT When I create the following module and run Connect-O365 the imported cmdlets will not be available. $scriptblock = { Function Connect-O365{ $o365cred = Get-Credential [email protected] $session365 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.outlook.com/powershell/" -Credential $o365cred -Authentication Basic -AllowRedirection Import-PSSession $session365 -AllowClobber } } New-Module -Name "Office 365" -ScriptBlock $scriptblock When I import the next module without the Connect-O365 function the imported cmdlets are available. $scriptblock = { $o365cred = Get-Credential [email protected] $session365 = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://ps.outlook.com/powershell/" -Credential $o365cred -Authentication Basic -AllowRedirection Import-PSSession $session365 -AllowClobber } New-Module -Name "Office 365" -ScriptBlock $scriptblock This appears to be a scope issue of some sort, just not sure how to get around it.

• Issue on dojo onlick event on html button

  I am a new kid with dojo, I got weird issue which I take lots of time and have not yet found out, assume I have 4 buttons: <button id="btnMoveFirst" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt; &lt;</button> <button id="btnMovePrev" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt;</button> <button id="btnMoveNext" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt;</button> <button id="btnMoveLast" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt; &gt;</button> And use dojo with event onclick as below: dojo.connect(dijit.registry.byId('btnMoveFirst'), "onclick", function(evt){ alert('test1'); }); dojo.connect(dijit.registry.byId('btnMovePrev'), "onclick", function(evt){ alert('test2'); }); dojo.connect(dijit.registry.byId('btnMoveNext'), "onclick", function(evt){ alert('test3'); }); dojo.connect(dijit.registry.byId('btnMoveLast'), "onclick", function(evt){ alert('test4'); }); But when I click any one of 4 buttons, or even any button in form, I got 4 alerts instead of only correct one. Does anyone know this?

• Can't see *all* databases in a remote SQL Server instance

  - by George

  Yesterday I posted a related question on StackOverflow. This problem involved not being able to see a SQL Server 2008 instance on another PC. I am not sure why adding the port number enabled me to see a SQL Server that I could not otherwise see, since the port number that I specified was, after all, the default port. Now I notice that I have another problem. While I can connect to the remote SQL 2008 Server instance, I cannot see all the databases in the instance. I am trying to connect to the 2008 instance from another PC using SQL Server 2008 Mgt Studio. I am connecting from a Windows 7 Ultimate PC to a Windows XP Pro PC. I suspect that my problem has something to do with not all database in the remote instance having the same version. For example, I "upgraded" a a SL 2005 database to 2008 by doing a backup frm 2005 and importing it into 2008. When I realized that this was not one of the database that I could see from my other PC, I noticed that the compatability level of the imported was still 2005, so I changed it to 2008. Still I could not see the database. I am sure that this is relevant: I just noticed that on my remote server, the sql node instance node, named "sql2008" says "version 10" when I am on the remote serfver, but when I connect to the sql2008 remote instance fron my local PC, the connection is shown locally as being a "SQL Servr version 8.0" instance. I suspect that locally, I am only being shown databases that are somehow in the remote 2008 instance but have not been upgraded. I guess I don't know what constitutes an upgraded database and I don not know who to connect to see all the databases, even if this requires multiple connections from the source PC.

• Calculate the retrieved rows in database Visual C#

  I am new in Visual C# and would want to know how to calculate the retrieved data from a database. Using the above GUI, when "Calculate" is click, the program will display the number of students in textBox1, and the average GPA of all students in textBox2.

• Is there a generic way of dealing with varying connection strings in C#?

  - by James Wiseman

  I have an application that needs to connect to a SQL database, and execute a SQL Agent Job. The connection string I am trying to access is stored in the registry, which is easily enough pulled out. This appliction is to be run on multiple computers, and I cannot guarantee the format of this connection string being consistent across these computers. Two that I have pulled out for example are: Data Source=Server1;Initial Catalog=DB1;Integrated Security=SSPI; Data Source=Server2;Initial Catalog=DB1;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False; I can use an object of type System.Data.SqlClient.SqlConnection to connect to the database with the first connection string, howevever, I get the following error when I pass the second to it: keyword not supported: 'provider' Similarly, I can use the an object of type System.Data.OleDb.OleDbConnection to connect to the database with the second connection string, howevever, I get the following error when I pass the first to it: An OLEDB Provider was not specified in the ConnectionString' I can solve this by scanning the string for 'Provider' and doing the connect conditionally, however I can't help but feel that there is a better way of doing this, and handle the connection strings in a more generic fashion. Does anyone have any suggestions?

• Remotely connecting two non-local computers with sockets

  - by Velizar Hristov

  This question seems like something very obvious to ask, and yet I spent more than an hour trying to find an answer. First I host and wait for someone to connect. Then, from another instance of the application, I try to connect with a socket - for the constructor, I use InetAddress, port. The port is always right, and everything works if I use "localhost" for the address. However, if I type my IP, I get an IOException. I even sent the application to someone else, gave him my IP, and it didn't work. The aim of the application is to connect two computers. It's in Java. Here is the relevant code. Server: ServerSocket serverSocket = new ServerSocket(port); Socket clientSocket = serverSocket.accept(); Client: InetAddress a = InetAddress.getByName(ip); Socket s = new Socket(a, port); I don't get past that. Obviously, the values of int port and String ip are taken from text fields. Edit: the purpose of my application is to connect two non-local computers.

• Android Bluetooth Cross Platform Interoperability

  - by Philipp

  Hi, I have a Bluetooth service that I programmed for .Net on a Windows machine and I would like my Android 2.1 phone to connect to it. The server is listening for the same UUID which the Android is using to connect. But the connection is failing. When I try to connect to devices that are not listening for that UUID, I get an exception with the message "Service discovery failed", but when I try to connect to the server that is listening for the right UUID a message box pops up saying: "There was a problem pairing with bluetooth device." And I get an exception with the message "Connection timed out." So it looks like the server and the Android are communicating, but there is some sort of failure during handshaking. I know that the Android requires that the server is paired with the phone and also encrypts the communication channel. Does anyone know which specifications are used to do this? I would love to get my server to respond properly to the connection attempt. Thanks!

• socket timeout and remove O_NONBLOCK option

  - by juxstapose

  Hello, I implemented a socket timeout and retry but in order to do it I had to set the socket as a non-blocking socket. However, I need the socket to block. This was my attempt at a solution to these two problems. This is not working. Subsequent send calls block but never send any data. When I connect without the select and the timeout, subsequent send calls work normally. References: C: socket connection timeout How to reset a socket back to blocking mode (after I set it to nonblocking mode)? Code: fd_set fdset; struct timeval tv; fcntl(dsock, F_SETFL, O_NONBLOCK); tv.tv_sec = theDeviceTimeout; tv.tv_usec = 0; int retries=0; logi(theLogOutput, LOG_INFO, "connecting to device socket num retrys: %i", theDeviceRetry); for(retries=0;retries<theDeviceRetry;retries++) { connect(dsock, (struct sockaddr *)&daddr, sizeof daddr); FD_ZERO(&fdset); FD_SET(dsock, &fdset); if (select(dsock + 1, NULL, &fdset, NULL, &tv) == 1) { int so_error; socklen_t slen = sizeof so_error; getsockopt(dsock, SOL_SOCKET, SO_ERROR, &so_error, &slen); if (so_error == 0) { logi(theLogOutput, LOG_INFO, "connected to socket on port %i on %s", theDevicePort, theDeviceIP); break; } else { logi(theLogOutput, LOG_WARN, "connect to %i failed on ip %s because %s retries %i", theDevicePort, theDeviceIP, strerror(errno), retries); logi(theLogOutput, LOG_WARN, "failed to connect to device %s", strerror(errno)); logi(theLogOutput, LOG_WARN, "error: %i %s", so_error, strerror(so_error)); continue; } } } int opts; opts = fcntl(dsock,F_GETFL); logi(theLogOutput, LOG_DEBUG, "clearing nonblock option %i retries %i", opts, retries); opts ^= O_NONBLOCK; fcntl(dsock, F_SETFL, opts);

• PHP: MySQL query duplicating update for no reason

  - by ThinkingInBits

  The code below is first the client code, then the class file. For some reason the 'deductTokens()' method is calling twice, thus charging an account double. I've been programming all night, so I may just need a second pair of eyes: if ($action == 'place_order') { if ($_REQUEST['unlimited'] == 200) { $license = 'extended'; } else { $license = 'standard'; } if ($photograph->isValidPhotographSize($photograph_id, $_REQUEST['size_radio'])) { $token_cost = $photograph->getTokenCost($_REQUEST['size_radio'], $_REQUEST['unlimited']); $order = new ImageOrder($_SESSION['user']['id'], $_REQUEST['size_radio'], $license, $token_cost); $order->saveOrder(); $order->deductTokens(); header('location: account.php'); } else { die("Please go back and select a valid photograph size"); } } ######CLASS CODE####### <?php include_once('database_classes.php'); class Order { protected $account_id; protected $cost; protected $license; public function __construct($account_id, $license, $cost) { $this->account_id = $account_id; $this->cost = $cost; $this->license = $license; } } class ImageOrder extends Order { protected $size; public function __construct($account_id, $size, $license, $cost) { $this->size = $size; parent::__construct($account_id, $license, $cost); } public function saveOrder() { //$db = Connect::connect(); //$account_id = $db->real_escape_string($this->account_id); //$size = $db->real_escape_string($this->size); //$license = $db->real_escape_string($this->license); //$cost = $db->real_escape_string($this->cost); } public function deductTokens() { $db = Connect::connect(); $account_id = $db->real_escape_string($this->account_id); $cost = $db->real_escape_string($this->cost); $query = "UPDATE accounts set tokens=tokens-$cost WHERE id=$account_id"; $result = $db->query($query); } } ?> When I die("$query"); directly after the query, it's printing the proper statement, and when I run that query within MySQL it works perfectly.

• Remote connection to SQL Server Express fails

  - by worlds-apart89

  I have two computers that share the same Internet IP address. Using one of the computers, I can remotely connect to a SQL Server database on the other. Here is my connection string: SqlConnection connection = new SqlConnection(@"Data Source=192.168.1.101\SQLEXPRESSNI,1433;Network Library=DBMSSOCN;Initial Catalog=FirstDB;Persist Security Info=True;User ID=username;Password=password;"); 192.168.1.101 is the server, SQLEXPRESSNI is the SQL Server instance name, and FirstDB is the name of the database. Now, I have another computer with a different Internet IP address. I want to connect to the server above using the third computer that does not belong to my local area network. I dont have access to that third computer at the moment, so I want to use (if possible) the client computer in LAN again. SqlConnection connection = new SqlConnection(@"Data Source=SharedInternetIP\SQLEXPRESSNI,1433;Network Library=DBMSSOCN;Initial Catalog=FirstDB;Persist Security Info=True;User ID=username;Password=password;"); Does not work Note that I am a beginner, so I am not quite sure what I am doing even though I know what I want to do. By passing the Internet IP to the SqlConnection object rather than the local IP address, how can I successfully connect to the server computer, using the client computer in the same network? Also note that my ultimate goal is to connect to the server with an external client, but I don't have access to that computer right now. I'd appreciate any help.
