• Change Keyboard Layout for Other Process

  - by SLaks

  I'm writing a program in C# that runs in the background and allows users to use a htokey to switch keyboard layouts in the active window. (Windows only supports CTRL+SHIFT & ALT+SHIFT) I'm using RegisterHotKey to catch the hotkey, & it's working fine. The problem is that I can't find any API to change the keyboard layout for the focused window. ActivateKeyboardLayout and LoadKeyboardLayout can only change the keyboard layout for the calling thread. Does anyone know how to change the keyboard layout for a different thread (the way the Language Bar does)?

• Posting an action works... but no image

  - by Brian Rice

  I'm able to post an open graph action to facebook using the following url: https://graph.facebook.com/me/video.watches with the following post data: video=http://eqnetwork.com/home/video.html?f=8e7b4f27-8cbd-4430-84df-d9ccb46da45f.mp4 It seems to be getting the title from the open graph metatags at the "video" object. But, it's not getting the image (even though one is specified in the metatag "og:image"). Also, if I add this to the post data: picture=http://eqnetwork.com/icons/mgen/overplayThumbnail.ms?drid=14282&subType=ljpg&w=120&h=120&o=1&thumbnail= still no image. Any thoughts? Brian

• String Manipulation: Splitting Delimitted Data

  - by Milli Szabo

  I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?

• Ruby on Rails: Accessing production database data for testing

  - by williamjones

  With Ruby on Rails, is there a way for me to dump my production database into a form that the test part of Rails can access? I'm thinking either a way to turn the production database into fixtures, or else a way to migrate data from the production database into the test database that will not get routinely cleared out by Rails. I'd like to use this data for a variety of tests, but foremost in my mind is using real data with the performance tests, so that I can get a realistic understanding of load times.

• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• Running an existing LINQ query against a dynamic object (DataTable like)

  - by TomTom

  Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows. I have a basic storage structure in place so far based on the OData sample code. My problem is: OData supports queries and expects me to hand in an IQueryable implementation. On the lowe rside, I dont have any query support. Not a joke - the provider returns tables and the WHERE clause is not supported. Performance is not an issue here - the tables are small. It is ok to sort them in the OData provider. My main problem is this. I submit a SQL statement to get out the data of a table. The result is some sort of ADO.NET data reader here. I need to expose an IQueryable implementation for this data to potentially allow later filtering. Any ide ahow to best touch that? .NET 3.5 only (no 4.0 planned for some time). I was seriously thinking of creating dynamic DTO classes for every table (emitting bytecode) so I can use standard LINQ. Right now I am using a dictionary per entry (not too efficient) but I see no real way to filter / sort based on them.

• jQuery UI Autocomplete plug-in pass in optional data for ajax call

  - by dev.e.loper

  I'm using jQuery UI Autocomplete plug-in. I'm giving it an URL to make an ajax call and retrieve data. I want to pass optional data parameters but not as part of URL. In the code they make a getJSON call and pass in 'request' parameter(which is an optional data parameter), however I don't see a way to get at this request parameter. this.source = function( request, response ) { $.getJSON( url, request, response ); };

• Under what circumstances are linked lists useful?

  - by Jerry Coffin

  Most times I see people try to use linked lists, it seems to me like a poor (or very poor) choice. Perhaps it would be useful to explore the circumstances under which a linked list is or is not a good choice of data structure. Ideally, answers would expound on the criteria to use in selecting a data structure, and which data structures are likely to work best under specified circumstances.

• SSIS Data Flow Task Excel Source

  - by Gerard

  Hi, I have a data flow task set up in SSIS. The source is from an Excel source not an SQL DB. The problem i seem to get is that, the package is importing empty rows. My data has data in 555200 rows, but however when importing the SSIS package imports over 900,000 rows. The extra rows are imported even though the other empty. When i then download this table into excel there are empty rows in between the data. Is there anyway i can avoid this? Thanks Gerard

• Google Web Toolkit or Microsoft Technology (Silverlight, ASP.NET)

  - by NativeByte

  We have a large code base in MFC and VB. A few applications are in .NET. All these applications interoperate with each other on the user's machine and also connect with Unix servers via sockets. Recently we have started discussing a re-write of our applications and possibility of moving a lot of these desktop applications to web (they would run in intranet). A straight forward way is rewritting them in one of the .NET technologies. But a suggestion about using Google Web tookit has popped up and the argument is that it would help creating applications that would run in a browser on both desktop and mobile devices. One of the key problem that I see is that GWT is a large abstraction over Javascript. This will require the team to learn GWT, Javascript, IDEs etc as their experience has been primarily Microsoft technologies and not Java. It would be easier for them to learn .NET technologies instead of GWT. I do not have a depth of GWT and its drawback pittfalls and do not know about a parallel Microsoft Technology that I should investigate. So I would appreciate if people here can share their views or experiences using GWT or equivalent Microsoft technology.

• Bind any version of MySql.Data using the app.config

  - by Martin Kirsche

  How do I bind any version or a range of versions of an assembly by using the app.config? I'm currently binding the MySql.Data assembly like this: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1" applies-to="v2.0.50727"> <qualifyAssembly partialName="MySql.Data" fullName="MySql.Data, Version=6.2.2.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d, processorArchitecture=MSIL"/> </assemblyBinding> </runtime> Any version of MySql.Data other than 6.2.2.0 is not working this way. The versions of this assembly are changing fast so I either want to bind any or all versions beginning with 6.2 to my application without changing the app.config each time.

• Recommendations for an in memory database vs thread safe data structures

  - by yx

  TLDR: What are the pros/cons of using an in-memory database vs locks and concurrent data structures? I am currently working on an application that has many (possibly remote) displays that collect live data from multiple data sources and renders them on screen in real time. One of the other developers have suggested the use of an in memory database instead of doing it the standard way our other systems behaves, which is to use concurrent hashmaps, queues, arrays, and other objects to store the graphical objects and handling them safely with locks if necessary. His argument is that the DB will lessen the need to worry about concurrency since it will handle read/write locks automatically, and also the DB will offer an easier way to structure the data into as many tables as we need instead of having create hashmaps of hashmaps of lists, etc and keeping track of it all. I do not have much DB experience myself so I am asking fellow SO users what experiences they have had and what are the pros & cons of inserting the DB into the system?

• DNS problems on CentOS fresh install

  - by Rick Koshi

  I'm having some DNS issues on a new box I'm installing with CentOS 6.2. I am able to look up names using nslookup, dig, or host. I am able to ping machines by name or by IP address. However, when I try other tools, such as ssh, wget, or yum, they are unable to resolve names. For example: # wget http://www.google.com --2012-03-08 14:48:06-- http://www.google.com/ Resolving www.google.com... failed: Name or service not known. wget: unable to resolve host address `www.google.com' # ssh www.google.com ssh: Could not resolve hostname www.google.com: Name or service not known # ping -c 1 www.google.com PING www.l.google.com (74.125.113.106) 56(84) bytes of data. 64 bytes from vw-in-f106.1e100.net (74.125.113.106): icmp_seq=1 ttl=46 time=43.6 ms --- www.l.google.com ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 59ms rtt min/avg/max/mdev = 43.665/43.665/43.665/0.000 ms # host www.google.com www.google.com is an alias for www.l.google.com. www.l.google.com has address 74.125.113.99 www.l.google.com has address 74.125.113.103 www.l.google.com has address 74.125.113.104 www.l.google.com has address 74.125.113.105 www.l.google.com has address 74.125.113.106 www.l.google.com has address 74.125.113.147 My /etc/nsswitch.conf file is the default, including this (standard) line: hosts: files dns /etc/resolv.conf is as set up by DHCP: ; generated by /sbin/dhclient-script nameserver 192.168.1.254 192.168.1.254 is a working DNS server (my DSL modem, working for years with other machines) Anyone know why ping would work, but ssh/wget would fail? Per NcA's suggestion, I tried changing /etc/resolv.conf to point to 8.8.8.8. Oddly enough, this does make it work. Obviously, my DSL modem is responding to DNS requests in some way that some parts of Linux's resolution system don't like. Looking at the tcpdump, I am unable to see what the difference is. Certainly, both servers are sending the same addresses. Here's the output from tcpdump -nn -X with the server set to the DNS server on the DSL modem. It's clearly replying with the correct addresses, but ssh/wget don't seem happy with it for some reason: 15:53:52.133580 IP 192.168.1.254.53 > 192.168.1.2.54836: 33157 7/0/0 CNAME www.l.google.com., A 74.125.115.105, A 74.125.115.106, A 74.125.115.147, A 74.125.115.99, A 74.125.115.103, A 74.125.115.104 (148) 0x0000: 4500 00b0 e33a 0000 ff11 53b1 c0a8 01fe E....:....S..... 0x0010: c0a8 0102 0035 d634 009c 7528 8185 8180 .....5.4..u(.... 0x0020: 0001 0007 0000 0000 0377 7777 0667 6f6f .........www.goo 0x0030: 676c 6503 636f 6d00 0001 0001 c00c 0005 gle.com......... 0x0040: 0001 0007 acd0 0008 0377 7777 016c c010 .........www.l.. 0x0050: c02c 0001 0001 0000 0001 0004 4a7d 7369 .,..........J}si 0x0060: c02c 0001 0001 0000 0001 0004 4a7d 736a .,..........J}sj 0x0070: c02c 0001 0001 0000 0001 0004 4a7d 7393 .,..........J}s. 0x0080: c02c 0001 0001 0000 0001 0004 4a7d 7363 .,..........J}sc 0x0090: c02c 0001 0001 0000 0001 0004 4a7d 7367 .,..........J}sg 0x00a0: c02c 0001 0001 0000 0001 0004 4a7d 7368 .,..........J}sh 15:53:52.135669 IP 192.168.1.254.53 > 192.168.1.2.54836: 65062- 0/0/0 (32) 0x0000: 4500 003c e33b 0000 ff11 5424 c0a8 01fe E..<.;....T$.... 0x0010: c0a8 0102 0035 d634 0028 98f9 fe26 8000 .....5.4.(...&.. 0x0020: 0001 0000 0000 0000 0377 7777 0667 6f6f .........www.goo 0x0030: 676c 6503 636f 6d00 001c 0001 gle.com.....

• Invoke an action that is using ASP.NET MVC [Authorize] from outside the application

  - by Nate Bross

  Is this possible? I'd like to expose a URL (action) such as http://mysever/myapp/UpdateHeartbeat/. In my MVC application it looks like [Authorize] [AcceptsVerbs(HttpVerbs.Post)] public ActionResult UpdateHeartbeat() { // update date in DB to DateTime.Now } Now, in my MVC application the user has logged in via FORMS authentication and they can execute that action to their hearts content. What I want to do, is hit that URL progromatically (as part of an API that I wouldl like to build) -- is there a way I can do that without removing the [Authorize] attribute and adding username/password as parameters to the POST?

• [Alfresco] property qualified-name in method getContentReader

  - by Ar3s

  Hi there, I first apologize for my poor english level and maybe for the stupidity of my question ;) I am on an alfresco project to learn how it works. I have to browse programatically my content repository and gather datas all along. In order to do that I guessed I had to use a ContentReader (I get from my ContentService) but the method getReader wants a nodeRef and a propertyQualifiedName. I am ok with the nodeRef, I get what it's needed for. But the propertyQualifiedName puzzles me, I barely get what it is but I frankly don't get how it is used. Reading some alfresco forum threads I get more and more scared that I dont even get how a reader works, I somewhere saw that a reader can read only one node and only one time per instance. If anyone knows a bit about the Java API for Alfresco Content Repository use I am all hears ! Cheers all !

• updating batches of data

  - by gaponte69

  I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

• Push or Pull to Excel for reporting data

  - by Nathan Fisher

  I am unsure which is the best way to go here. I have a third party Excel 2003 spreadsheet that needs to be filled in on a monthly basis and emailed. Currently it is a manual process and I am in the process of automating the generation of the spreadsheet. I have been throwing around different ideas of how to get the data into the spreadsheet. I have thought of using SSRS to create a report that is in a similar format and get the user to cut and past. Alternatively writing a VBA addin that retrieves that data from a webservice and then adds the data to the spreadsheet. Or using the third party spreadsheet as a template and open it on the server via oledb and adding the data then serving it as a downloadable file. Which is better or are the better solutions out there?

• How can I visualise a "broken" hierarchical dataset?

  I have a reasonably large datatable structured something like this: StaffNo Grade Direct Boss2 Boss3 Boss4 Boss5 Boss6 ------- ----- ----- ----- ----- ----- ----- ----- 10001 1 10002 10002 10057 10094 10043 10099 10002 2 10057 NULL 10057 10094 10043 10099 10003 1 10004 10004 10057 10094 10043 10099 10004 2 10057 NULL 10057 10094 10043 10099 10057 3 10094 NULL NULL 10094 10043 10099 etc.... i.e. a unique id , their level (grade) in the hierarchy, a record of their bosses ID and the IDs of the supervisors above. (The 2,3,4, etc refers to the boss at that particular grade). The system relies on a strict hierarchy - if you are my boss (/parent) then your boss must be my grandparent. Unfortunately this rule is not enforced within the data model and the data ultimately comes from other systems which don't even know about the rule, let alone observe it. So you and I may share the same boss, but our bosses boss won't be the same. note: I cannot change the data model I cannot fix the data at source. So (for the moment) I have to fix the data once it's in place. Once a fortnight someone will do something which breaks the model and I'll need to modify the procs slightly to resolve. Not ideal, but I'm stuck with this for the next six months. Anyway, specific queries are easy to produce but I find it hard to keep track of the bigger picutre. The application which sits on this runs without complaint regardless but navigating around the system becoming extraordinarily confusing. So my question is: Can anyone recommend a tool (or technique) for generating some kind of "broken tree" diagram in this sort of circumstances? I don't want something that will fix things for me, or attempt statistical analysis but at least something that will give a visual indication of how broken it is at any one time. Note : At the moment this is in a SQL Server database but I'm open to ideas utilising C#, Perl or Python.
