  • How to add a Drupal CCK Custom Field which supports unique identification of multiple values

    - by jtw12
    I need to create a custom field that supports multiple values which can be uniquely identified (beyond the delta field which changes when the values are re-ordered). I have created a module for the field and specified the two database columns that I would like CCK to use (one for the value and one for the ID) but I am not sure where the entry point is for adding in a unique id for each value (probably will just take the id from a sequence).

  • How to efficiently implement a blocking call with Rails, while letting the client wait for the reply

    - by Kyle Heironimus
    We have a web service written in Rails. The API is published and we cannot change it. Our app communicates with a remote web service that sometimes hangs or takes several seconds to reply. Client -> Our Web Service -> Remote Web Service Currently, if the remote web service hangs for 5 seconds, one of our rails processes on our web service also hangs with it, which is what we need to avoid. I've seen things such as mod-x-sendfile, modporter, and delayed jobs, but the best I can tell, they all assume the client is not waiting for an answer. Since the API is already established, we cannot tell the client "I'm attempting to do what you want, check back later for the answer." The best option we have come up with so far is to add a second, non-rails web server running eventmachine to process these particular calls. Is there a better way?

  • Can I float a block of text like an image?

    - by george.entenman.name
    If you change "float:right" to "float:left" in this W3schools example, you'll get an image floating to the left of the paragraph. I want to do the same thing with a block of text. The purpose is to be able to have little annotations to the left of paragraphs. If you know of any way to do this, I'd be very grateful. I'd be really grateful (and amazed) if there were a way to place this annotation midway in a paragraph and have text flow around it. I've searched all over for an answer but possibly don't know how to ask the question so that search engines can help me. So now I'm appealing to humans!!

  • Inserting records in Mysql with INSERT IGNORE and NULL values

    - by Homer1980ar
    I have a partitioned table InnoDB with several fields. I'm trying to avoid duplicates on insert. Let's say: Field1 int null Field2 int null Field3 int null Field4 int null Field5 int null I have created a UNIQUE index on those fields. I try to insert some records with NULL values and then try to reinsert them with IGNORE feature on MySql. Unfortunately it seems to replicated the records when using NULL values. If I try with zeros instead of NULL cases everything works, but I do need the nulls there. Any idea? Thanks, Leonardo

  • How to hide helper functions from public API in c

    - by emge
    I'm working on a project and I need to create an API. I am using sockets to communicate between the server (my application) and the clients (the other applications using my API). This project is in c not C++ I come from a linux background and this is my first project using Windows, Visual Studio 2008, and dll libraries. I have communication working between the client and server, but I have some that is duplicated on both projects. I would like to create a library (probably a dll file), that both projects can link to so I don't have to maintain extra code. I also have to create the library that has the API that I need to make available for my clients. Within the API functions that I want public are the calls to these helper functions that are "duplicated code", I don't want to expose these functions to my client, but I do want my server to be able to use those functions. How can I do this? I will try to clarify with an example. This is what I started with. Server Project: int Server_GetPacket(SOCKET sd); int ReceiveAll(SOCKET sd, char *buf, int len); int VerifyLen(char *buf); Client Project: int Client_SendCommand(int command); int Client_GetData(int command, char *buf, int len); int ReceiveAll(SOCKET sd, char *buf, int len); int VerifyLen(char *buf); This is kind of what I would like to end up with: //Server Project: int Server_GetPacket(SOCKET sd); // library with public and private types // private API (not exposed to my client) int ReceiveAll(SOCKET sd, char *buf, int len); int VerifyLen(char *buf); // public API (header file available for client) int Client_SendCommand(int command); int Client_GetData(int command, char *buf, int len); Thanks any help would be appreciated.

  • 'ErrorMessageResourceType' property specified was not found. on XmlSerialise

    - by Redeemed1
    In my ASP.Net MVC app I have a Model layer which uses localised validation annotations on business objects. The code looks like this: [XmlRoot("Item")] public class ItemBo : BusinessObjectBase { [Required(ErrorMessageResourceName = "RequiredField", ErrorMessageResourceType = typeof(StringResource))] [HelpPrompt("ItemNumber")] public long ItemNumber { get; set; } This works well. When I want to serialise the object to xml I get the error: "'ErrorMessageResourceType' property specified was not found" (although it is lost beneath other errors, it is the innerexception I am trying to work on. The problem therefore is the use of the DataAnnotations attributes. The relevant resource files are in another assembly and are marked as 'public' and as I said everything works well until I get to serialisation. I have references to the relevant DataAnnotations class etc in my nunit tests and target class. By the way, the HelpPrompt is another data annotation I have defined elsewhere and is not causing the problem. Furthermore if I change the Required attribute to the standard format as follows, the serialisation works ok. [Required(ErrorMessage="Error")] Can anyone help me?

  • How can I write to a single xml file from two programs at the same time?

    - by Tom Bushell
    We recently started working with XML files, after many years of experience with the old INI files. My coworker found some CodeProject sample code that uses System.Xml.XmlDocument.Save. We are getting exceptions when two programs try to write to the same file at the same time. System.IO.IOException: The process cannot access the file 'C:\Test.xml' because it is being used by another process. This seems obvious in hindsight, but we had not anticipated it because accessing INI files via the Win32 API does not have this limitation. I assume there's some arbitration done by the Win32 calls that work at a higher level than the the XmlDocument.Save method. I'm hoping there are higher level XML routines somewhere in the .Net library that work similarily to the Win32 functions, but don't know where to start looking. Or maybe we can set up our file access permissions to allow multiple programs to write to the same file? Time is short (like almost all SW projects), and if we can't find a solution quickly, we'll have to hold our noses and go back to INI files.

  • Image Grabbing with False Referer

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

  • How to know when a specific process is stuck?

    - by Carlos Blanco
    Is there a way to know when a specific process is "stuck" in Java? I'm running an external application from my java program. Sometimes, this app hangs. I would like to know when this app stops working so I can kill it from my code. I'm thinking of some type of monitoring from a different thread in my code. Any toughts?

  • video tag in iphone status

    - by David
    Is there any movie that actually works in iPhone/iPad safari using the video tag? We tried so many formats and code snippets. I've heard that mp4/h264 should work, but not for us. Can anyone point me to a working example online? If you know the code or specs/formats for the videotag on iphone, that would be great.

  • Connecting std::basic_ofstream<unsigned char> to a FIFO. bad_cast exceptions

    - by Mike B
    Using gcc 4.4.3 on Linux 2.6.32, I get bad_cast exceptions when connecting std::basic_ofstream to a FIFO. Stepping though the debugger, I can see that the error is generated at various places in the standard library because the _M_codecvt member of the stream or filebuf object is NULL. Exactly where it happens depends on the order of operations, but it appears to be the same cause in each. So am I doing something fundamentally stupid here? ofstream and ifstream work fine. Is there some reason that you shouldn't attach a stream of anything besides char to a FIFO? Thanks in advance.

  • otal Number of records required in paged grid

    - by sumitchauhan
    I am using a data grid and has bound a data source with it. I am trying to get the total number of records in the grid in overriden InitializePager method from pagedDataSource DataSourceCount. I thought DataSourceCount returns number of records from SelectCountMethod of ObjectDataSource. But DataSourceCount is giving me the page size and not the total number of records, whereas when I debug and see in SelectCountMethod it is returning correct number of total Records. I am not sure how to get the data from SelectCountMethod in DataGrid.

  • Count the number of times a string appears within a string...

    - by onekidney
    I simply have a string that looks something like this: "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false" All I want to do is to count how many times the string "true" appears in that string. I'm feeling like the answer is something like String.CountAllTheTimesThisStringAppearsInThatString() but for some reason I just can't figure it out. Help?

  • Help with error creating SharePoint list (probably due to privilege issues)

    I'm getting an error when trying to activate a webpart. It activates fine in one setup , but fails in a different one. Administrator in both. Seems like it fails because it's not able to create the list. The error is: Message: Value cannot be null.

  • Cannot access shares via full domain name on Server 2008R2

    - by Stu
    Hi, I have a strange issue. We have a 2008R2 PDC and BDC. I can join the domain fine and everything seems "normal". However, on some of the other 2008R2 servers, I am unable to do things like a gpupdate. When I try, I get an error that the clocks are wrong (they aren't) and that I don't have permission. So far, this has only affected our 2008R2 servers -- the Win 7 clients are fine. The really strange things is if I browse to: \\mydomain.lan\sysvol - I get the error. But! if I browse to: \\MYDOMAIN\sysvol - it works fine. I can also access the \hostname.domain\sysvol remotely for each of the DC's and it's fine. So in short, it appears the permissions are fine since I can access them all individually on the same account. It also seems unlikely it's on the server as most clients can access it fine. The only drama I have is when I try to use the full domain name (which of course gpupdate does) on a 2008R2 server. Also, it's not just sysvol...netlogon has the same issues too on the affected machines. Any ideas? Thanks! Drew

  • Postgresql server will not start

    - by Claudiu
    I'm on Windows 7. I restarted my computer. I then tried to connect to the database and got an error. I don't remember which one in particular but it was some connection issue. I decided to try to restart the server, so I clicked on "Restart server" from the start menu. This blocked. After a few minutes I killed the process and tried again, only to get a "The service is starting or stopping. Please try again later." message. I rebooted the computer again, tried to start again, and got the same error. I killed the pg_ctl process and tried starting it manually, but that didn't work either: C:\Users\DrClaud>cscript "C:\Program Files\PostgreSQL\8.3\scripts\serverctl.vbs" start wait Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation.
