  • How can I rewrite this (cleanly) without gotos?

    - by Jared P
    How can I do this cleanly without gotos? loop: if(condition1){ something(); } else if (condition2) { somethingDifferent(); } else { mostOfTheWork(); goto loop; } I'd prefer not to use breaks as well. Furthermore, it is expected to loop several (adv 40) times before doing something else, so the mostOfTheWork part would most likely be as high up as possible, even if just for readability. Thanks in advance.

  • Facebook access_token: how do I get it once the user accepted my app?

    - by hoktar
    When a user visits my site which contains a facebook app the first time, it requires him to allow it and he gets promted to do that, then I get the code which I can convert to an access_token. So far so good. But how do I get the token once the user has already visited the site? As long as this token form the first time is active everything is fine. But how do I get another token when the user had already allowed the app a week ago and is only visiting my page again?

  • Mercurial vs Subversion. Whose performance is better?

    - by Chicago
    There are a lot of articles about SVN vs. Hg in general. I would like to concentrate only on performance. Real-live experiences preferred. Here is my set-up: (future setup) Windows with IIS fro Hg (current setup) SVN 1.3.2 on top of apache under windows I would like to have statistics for most commons operations (commits, stats, local/remote pulls, pushes, etc...). I am not really sure what are the most common operations for Hg.

  • Why delete and recreate a querydef object when you can just change the .SQL property?

    - by dblE
    Do you remember the venerable old Microsoft Query by Form (QBF) VBA example from back in the day link that recommended that you delete an existing query and then recreate it dynamically?: On Error Resume Next db.QueryDefs.Delete ("qryResults") On Error GoTo 0 Set qdf = db.CreateQueryDef("qryResults", "SELECT p.*... Why not just change the SQL property of the querydef object? qdf.SQL = "SELECT p.*... I am wondering if anyone knows why the MS engineers wrote an example that suggests that you delete and then recreate a query instead of simply changing the SQL property? I would guess that the act of deleting and recreating objects over time could contribute to corruption and bloating in your front end, not to mention changing the SQL property is so much simpler. Does anyone have more insight into this?

  • Utilizing back and forward browser buttons for web apps

    - by at
    How do I use the back and forward browser buttons to navigate my javascript/jQuery web application? I know I can do window.location.href = 'this_url#placeholder' and then perform the appropriate action. But when I do that, the browser scrolls to the element with that placeholder id (or to the top if there wasn't one). How do I get the browser to not scroll anywhere? I've seen this on other sites like facebook, what's the appropriate mechanism for this?

  • Announcing: Improvements to the Windows Azure Portal

    - by ScottGu
    Earlier today we released a number of enhancements to the new Windows Azure Management Portal.  These new capabilities include: Service Bus Management and Monitoring Support for Managing Co-administrators Import/Export support for SQL Databases Virtual Machine Experience Enhancements Improved Cloud Service Status Notifications Media Services Monitoring Support Storage Container Creation and Access Control Support All of these improvements are now live in production and available to start using immediately.  Below are more details on them: Service Bus Management and Monitoring The new Windows Azure Management Portal now supports Service Bus management and monitoring. Service Bus provides rich messaging infrastructure that can sit between applications (or between cloud and on-premise environments) and allow them to communicate in a loosely coupled way for improved scale and resiliency. With the new Service Bus experience, you can now create and manage Service Bus Namespaces, Queues, Topics, Relays and Subscriptions. You can also get rich monitoring for Service Bus Queues, Topics and Subscriptions. To create a Service Bus namespace, you can now select the “Service Bus” tab in the Windows Azure portal and then simply select the CREATE command: Doing so will bring up a new “Create a Namespace” dialog that allows you to name and create a new Service Bus Namespace: Once created, you can obtain security credentials associated with the Namespace via the ACCESS KEY command. This gives you the ability to obtain the connection string associated with the service namespace. You can copy and paste these values into any application that requires these credentials: It is also now easy to create Service Bus Queues and Topics via the NEW experience in the portal drawer.  Simply click the NEW command and navigate to the “App Services” category to create a new Service Bus entity: Once you provision a new Queue or Topic it can be managed in the portal.  Clicking on a namespace will display all queues and topics within it: Clicking on an item in the list will allow you to drill down into a dashboard view that allows you to monitor the activity and traffic within it, as well as perform operations on it. For example, below is a view of an “orders” queue – note how we now surface both the incoming and outgoing message flow rate, as well as the total queue length and queue size: To monitor pub/sub subscriptions you can use the ADD METRICS command within a topic and select a specific subscription to monitor. Support for Managing Co-Administrators You can now add co-administrators for your Windows Azure subscription using the new Windows Azure Portal. This allows you to share management of your Windows Azure services with other users. Subscription co-administrators share the same administrative rights and permissions that service administrator have - except a co-administrator cannot change or view billing details about the account, nor remove the service administrator from a subscription. In the SETTINGS section, click on the ADMINISTRATORS tab, and select the ADD button to add a co-administrator to your subscription: To add a co-administrator, you specify the email address for a Microsoft account (formerly Windows Live ID) or an organizational account, and choose the subscription you want to add them to: You can later update the subscriptions that the co-administrator has access to by clicking on the EDIT button, and then select or deselect the subscriptions to which they belong. Import/Export Support for SQL Databases The Windows Azure administration portal now supports importing and exporting SQL Databases to/from Blob Storage.  Databases can be imported/exported to blob storage using the same BACPAC file format that is supported with SQL Server 2012.  Among other benefits, this makes it easy to copy and migrate databases between on-premise and cloud environments. SQL Databases now have an EXPORT command in the bottom drawer that when pressed will prompt you to save your database to a Windows Azure storage container: The UI allows you to choose an existing storage account or create a new one, as well as the name of the BACPAC file to persist in blob storage: You can also now import and create a new SQL Database by using the NEW command.  This will prompt you to select the storage container and file to import the database from: The Windows Azure Portal enables you to monitor the progress of import and export operations. If you choose to log out of the portal, you can come back later and check on the status of all of the operations in the new history tab of the SQL Database server – this shows your entire import and export history and the status (success/fail) of each: Enhancements to the Virtual Machine Experience One of the common pain-points we have heard from customers using the preview of our new Virtual Machine support has been the inability to delete the associated VHDs when a VM instance (or VM drive) gets deleted. Prior to today’s release the VHDs would continue to be in your storage account and accumulate storage charges. You can now navigate to the Disks tab within the Virtual Machine extension, select a VM disk to delete, and click the DELETE DISK command: When you click the DELETE DISK button you have the option to delete the disk + associated .VHD file (completely clearing it from storage).  Alternatively you can delete the disk but still retain a .VHD copy of it in storage. Improved Cloud Service Status Notifications The Windows Azure portal now exposes more information of the health status of role instances.  If any of the instances are in a non-running state, the status at the top of the dashboard will summarize the status (and update automatically as the role health changes): Clicking the instance hyperlink within this status summary view will navigate you to a detailed role instance view, and allow you to get more detailed health status of each of the instances.  The portal has been updated to provide more specific status information within this detailed view – giving you better visibility into the health of your app: Monitoring Support for Media Services Windows Azure Media Services allows you to create media processing jobs (for example: encoding media files) in your Windows Azure Media Services account. In the Windows Azure Portal, you can now monitor the number of encoding jobs that are queued up for processing as well as active, failed and queued tasks for encoding jobs. On your media services account dashboard, you can visualize the monitoring data for last 6 hours, 24 hours or 7 days. Storage Container Creation and Access Control Support You can now create Windows Azure Storage storage containers from within the Windows Azure Portal.  After selecting a storage account, you can navigate to the CONTAINERS tab and click the ADD CONTAINER command: This will display a dialog that lets you name the new container and control access to it: You can also update the access setting as well as container metadata of existing containers by selecting one and then using the new EDIT CONTAINER command: This will then bring up the edit container dialog that allows you to change and save its settings: In addition to creating and editing containers, you can click on them within the portal to drill-in and view blobs within them.  Summary The above features are all now live in production and available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today.  Visit the Windows Azure Developer Center to learn more about how to build apps with it. We’ll have even more new features and enhancements coming later this month – including support for the recent Windows Server 2012 and .NET 4.5 releases (we will enable new web and worker role images with Windows Server 2012 and .NET 4.5, and support .NET 4.5 with Websites).  Keep an eye out on my blog for details as these new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • How do I deny access to everybody but me in Windows 7?

    - by GregH
    I am trying to set up a file server on my my Windows 7 Pro system at home. I set up one common "Share" folder that I have shared/published. Within the share folder I want to have individual folders for me and my wife...that is only I can read/write my folder and only my wife can read/write to her folder and neither of us can read the contents of the other person's folder. Then I want to have a "public" folder where we can both read/write to contents of the folder as well as any sub-folders created, but my "kids" account can only read from this folder and sub folders. It seems really confusing to set up something like this and it really shouldn't. I am really confused between the "allow", "deny", and dimmed check boxes in the security tab. It seems that if I "Deny" access to "Everyone" on my private folder, then I don't even have access to it. Windows security seems backwards from the rest of the world's security models. If I am in two groups and I deny access to one of the groups but allow access to the other group then Windows security denies me access as I am in one of the groups that has access disallowed. Very confusing.

  • How can I access one desktop session from another on the same machine?

    - by d3vid
    I want to run a desktop session as user A, and from that session access a different desktop session as user B. This way I can test, screencast or share my screen from session B, while having access to apps/resources in session A that I do not want running/visible in session B. What application can I do this with? I assume some kind of a remote desktop client/server is what I'm looking for. So far I have tried: VNC. Logged in as user A and user B. In session B run Desktop Sharing. Switched to session A. Tried to access share with Remmina. Failed. (Can get image to appear but it's frozen.) x2go. Installed server and client from stable PPA (needed a workaround for installation to succeed). Created a connection which starts then fails instantly. Discovered mailing list post suggesting that accessing localhost is not supported. On the non-remote front: VirtualBox. Created a minimal virtual machine for session B. Too resource heavy. Am I attempting the impossible? Should I be looking for something other than a remote desktop tool?

  • How do I access shared folders on Ubuntu server from Mac OS?

    - by Stephen
    I have an old dell desktop running ubuntu 11.04, I also have samba installed on it. I'm trying to access the shared folders on the Ubuntu machine from my Mac, so I go into 'Finder', click on 'Go' and 'Connect to Server'. I type in the ip address of the ubuntu machine smb://xxx.xxx.x.xx and click connect, I can then see the list of shared folders from the ubuntu machine so I know its making a connection. But when I access the 'Music' folder I get an error message stating: There was an error connecting to the server "xxx.xxx.x.xx". Check the server name or IP address, and try again. Any thoughts anyone ? EDIT I have a external hard drive attached to the server, and the folders I'm trying to access are located on that external hard drive. The location of the folder is /media/HD-CELU2/test, so I think the path from Finder should be smb://xxx.xxx.x.xx/media/HD-CELU2/test, but having tested this, I'm still not getting in. P.S. I'm using Samba as I have a Windows machine on my home network as well.

  • Cannot access personal website from home IP. More details inside.

    - by GX67
    This is a recent problem I've been having. My site can be accessed from almost everywhere else except from my home IP, where I do most of my editing/updating, etc. I've tested my connection from my school's network, a friend's connection from out of state (multiple states), and through a tethered connection with my friend's Android. It works in all those cases, both viewing, accessing the cPanel, and using FTP. Here's the problem that happens to me when I try to view it from my home IP: The page times out in Firefox, IE, and Chrome. Using the cmd, I ran tracert and ping, both as failed attempts. Log here. downforeveryoneorjustme.com says my site is up. So do the other site checkers. I can't access my cPanel or FTP accounts. I can't access the host site. (I use perfectz.info for hosting, and I can't access their site either.) System settings: No firewall enabled. Ports are seemingly properly forwarded. (e.g. The ports are open in the router settings, and are open everywhere else.) I have an email forwarder set up from the cPanel that works just fine. (i.e. I can receive emails sent to that address. If any other information is needed, I'll do my best to provide it. UPDATE @ilhan: I use two things: 1) The site cPanel from in-browser. 2) Dreamweaver CS5 FTP. @Matthias: I tested both, and it passes the dual stack with a 10/10. What should I do then?

  • What is an effective way to convert a shared memory-mapped system to another data access model?

    - by Rob Jones
    I have a code base that is designed around shared memory. Each process that needs to access the memory maps it into its own address space. The data structures in the shared memory are directly accessed, that is, there is no API. For example: Assume the following: typedef struct { int x; int y; struct { int a; int b; } z; } myStruct; myStruct s; Then a process might access this structure as: myStruct *s = mapGlobalMem(); And use it as: int tmpX = s->x; The majority of the information in the global structure is configuration information that is set once and read many times. I would like to store this information in a database and develop an API to access the database. The problem is, these references are sprinkled throughout the code. I need a way to parse the code and identify global structure references that will need to be refactored. I've looked into using ANTLR to create a parser that will identify references to a small set of structures and enter them into a custom symbol table. I could then use this symbol table to identify which source files need to be refactored. It looks like a promising approach. What other approaches are there? Of course, I'm looking for a programmatic approach. There are far too many source files to examine each one visually. This is all ordinary ANSI C. Nothing else.

  • What credentials should I use to access a Windows share?

    - by JMCF125
    Hi, I have installed Samba and CIFS and all that, followed a bunch of tutorials, but still I can't access a share in the separate Windows 7 machine. Before I could access a share in Ubuntu from Windows, but although now I can't for whatever reason; the error of the attempt to mount the Windows share is the same: 13, asking for credentials (the computer with Windows is off now, but I can add the exact error message later). In /etc/fstab I have: # ... (help info) ... # <file system> <mount point> <type> <options> <dump> <pass> # ... (mounting points that don't matter for the question) ... //192.168.1.2/C\:/Users/Public/Documents /srv/Z\:/ cifs user=guest,password=,uid=1000,iocharset=utf8 0 0 I also tried options such as username=guest,uid=1000,iocharset=utf8 and guest,uid=1000,iocharset=utf8, which, of course, don't work. What user am I supposed to use? (user=user; username=user; my credentials in the Windows and Ubuntu machines do not work, at least with the syntax I tried - similar to this). Even if this worked it's not actually what I want. I wanted to setup an authentication for any one trying to access the drive (it's currently 777, for the Linux share as well) and put a limit/quota on the share's use (as I see Z:on Windows, it allows for the entire C:drive to be filled). Thank you in advance. I'd be glad if you suggested a way to do this even without the last paragraph.

  • How can I generate a client proxy for a WCF service with an HTTPS endpoint?

    - by ng5000
    Might be the same issue as this previuos question: WCF Proxy but not sure... I have an HTTPS service connfigured to use transport security and, I hope, Windows credentials. The service is only accessed internally (i.e. within the intranet). The configuration is as follows: <configuration> <system.serviceModel> <services> <service name="WCFTest.CalculatorService" behaviorConfiguration="WCFTest.CalculatorBehavior"> <host> <baseAddresses> <add baseAddress = "https://localhost:8000/WCFTest/CalculatorService/" /> </baseAddresses> </host> <endpoint address ="basicHttpEP" binding="basicHttpBinding" contract="WCFTest.ICalculatorService" bindingConfiguration="basicHttpBindingConfig"/> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/> </service> </services> <bindings> <basicHttpBinding> <binding name="basicHttpBindingConfig"> <security mode="Transport"> <transport clientCredentialType = "Windows"/> </security> </binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="WCFTest.CalculatorBehavior"> <serviceAuthorization impersonateCallerForAllOperations="false" principalPermissionMode="UseWindowsGroups" /> <serviceCredentials > <windowsAuthentication allowAnonymousLogons="false" includeWindowsGroups="true" /> </serviceCredentials> <serviceMetadata httpsGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="False" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> When I run the service I can't see the service in IE. I get a "this page can not be displayed" error. If I try and create a client in VS2008 via the "add service reference" wizard I get this error: There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. Metadata contains a reference that cannot be resolved: 'https://localhost:8000/WCFTest/CalculatorService/'. An error occurred while making the HTTP request to https://localhost:8000/WCFTest/CalculatorService/. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. If the service is defined in the current solution, try building the solution and adding the service reference again. I think I'm missing some fundamental basics here. Do I need to set up some certificates? Or should it all just work as it seems to do when I use NetTcpBinding? Thanks

  • Coherent access to mainframe files from Win32 application and IBM RDZ/Eclipse?

    - by Ira Baxter
    I have a suite of tools for processing IBM COBOL source code; these tools are built as Win32 applications and talk to Windows (including network) files using traditional Windows file system calls (open, close, read, write) and work just fine, thank you. I'd like to integrate these with Eclipse; we understand how to get Eclipse to do UI for us we think. The problem is that Eclipse/RDZ users access mainframe files through some IBM magic. In How does RDZ access mainframe files I tried to understand how Eclipse accessed files on a mainframe. Apparantly Eclipse/RDZ has a secret filesystem access backdoor not available to normal mortals. At issue is how our tools, reading some Windows-accessible file (local disk file, NFS to mainframe, ...) can associate such files with the files that Eclipse can access or is using? Ideally we'd like UI-integrated versions of our tools take an Eclipse file-name string for a mainframe file, pass it to our Windows application to process, have the Windows application open/read/process the file, and return results associated with that file to the Eclipse UI. Is there a canonical file name path that would be used with mainframe NFS that would be equivalent to the name or access object the Eclipse RDZ used to access the same file? Are all operations doable internally by Eclipse, doable by the mainframe NFS [for instance, can NFS read/update an element in a partitioned data set? Can Eclipse RDZ? Does it matter?] Is the mainframe file access available to custom Java code running under Eclipse RDZ (e.g., equivalents of open/close/read/write based on filename/path/something?) If so, can somebody steer me towards documentation describing the access methods? Anybody else already solve this problem or have a good suggestion?
