  • How to speedup perforce auto resolve?

    - by Sorin Sbarnea
    I would like to know how to speedup the perforce auto resolve when doing integration (merge yours and theirs if no conflicts exists). Currently is taking hours for ~5000 files when running it using a proxy server even if the proxy server has the files pre-cached. Also p4v interface doesn't give you any hint regarding the progress of the task, you do not know if it will finish in a second or next year.

  • Delphi SOAP Envelope and WCF

    - by Chris
    Hi all, I am working on a system that provides a soap interface. One of the systems that are going to use the interface is coded in Delphi 7. The web service is developed with WCF, basic http binding, SOAP 1.1. If I use SOAP UI (JAVA), the service works properly. But Delphi seems to do special things here ;) This is how the message looks like in SOAP UI: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.xxx.de/xxx"> <soapenv:Header/> <soapenv:Body> <ser:GetCustomer> <!--Optional:--> <ser:GetCustomerRequest> <!-- this is a data contract --> <ser:Id>?</ser:Id> </ser:GetCustomerRequest> </ser:GetCustomer> </soapenv:Body> </soapenv:Envelope> I am not a delphi developer , but I developed a simple test client to see what's going wrong. This what Delphi sends as a SOAP envelope. <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS2="http://services.xxx.de/xxx"> <NS1:GetCustomer xmlns:NS1="http://services.xxx.de/xxx"> <GetCustomerRequest href="#1"/> </NS1:GetCustomer> <NS2:GetCustomerRequest id="1" xsi:type="NS2:GetCustomerRequest"> <Id xsi:type="xsd:int">253</Id> </NS2:GetCustomerRequest> </SOAP-ENV:Body> </SOAP-ENV:Envelope> WCF throws an error that is in German language... ;) Es wurde das Endelement "Body" aus Namespace "http://schemas.xmlsoap.org/soap/envelope/" erwartet. Gefunden wurde "Element "NS2:GetCustomerRequest" aus Namespace "http://services.xxx.de/xxx"". Zeile 1, Position 599. Means something like The Body was expected. But instead the Element "NS2:GetCustomerReques" was found. Now my questions is: Can I somehow change the way Delphi creates the envelope? Or are the ways to make WCF work with such message formats? Any help is greatly appreciated!

  • WCF ResponseFormat For WebGet

    - by michael lucas
    WCF offers two options for ResponseFormat attribute in WebGet annotation in ServiceContract. [ServiceContract] public interface IService1 { [OperationContract] [WebGet(UriTemplate = "greet/{value}", BodyStyle = WebMessageBodyStyle.Bare)] string GetData(string value); [OperationContract] [WebGet(UriTemplate = "foo", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)] string Foo(); The options for ResponseForamt are WebMessageFormat.Json and WebMessageFormat.Xml. Is it possible to write my own web message format? I would like that when client calls foo() method he gets raw string - without json or xml wrappers.

  • Using the Rijndael Object in VB.NET

    - by broke
    I'm trying out the Rijndael to generate an encrypted license string to use for our new software, so we know that our customers are using the same amount of apps that they paid for. I'm doing two things: Getting the users computer name. Adding a random number between 100 and 1000000000 I then combine the two, and use that as the license number(This probably will change in the final version, but I'm just doing something simple for demonstration purposes). Here is some sample codez: Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim generator As New Random Dim randomValue As Integer randomValue = generator.Next(100, 1000000000) ' Create a new Rijndael object to generate a key ' and initialization vector (IV). Dim RijndaelAlg As Rijndael = Rijndael.Create ' Create a string to encrypt. Dim sData As String = My.Computer.Name.ToString + randomValue.ToString Dim FileName As String = "C:\key.txt" ' Encrypt text to a file using the file name, key, and IV. EncryptTextToFile(sData, FileName, RijndaelAlg.Key, RijndaelAlg.IV) ' Decrypt the text from a file using the file name, key, and IV. Dim Final As String = DecryptTextFromFile(FileName, RijndaelAlg.Key, RijndaelAlg.IV) txtDecrypted.Text = Final End Sub That's my load event, but here is where the magic happens: Sub EncryptTextToFile(ByVal Data As String, ByVal FileName As String, ByVal Key() As Byte, ByVal IV() As Byte) Dim fStream As FileStream = File.Open(FileName, FileMode.OpenOrCreate) Dim RijndaelAlg As Rijndael = Rijndael.Create Dim cStream As New CryptoStream(fStream, _ RijndaelAlg.CreateEncryptor(Key, IV), _ CryptoStreamMode.Write) Dim sWriter As New StreamWriter(cStream) sWriter.WriteLine(Data) sWriter.Close() cStream.Close() fStream.Close() End Sub There is a couple things I don't understand. What if someone reads the text file and recognizes that it is Rijndael, and writes a VB or C# app that decrypts it? I don't really understand all of this code, so if you guys can help me out I will love you all forever. Thanks in advance

  • Using JAXB to unmarshal/marshal a List<String> - Inheritance

    - by gerry
    I've build the following case. An interface for all JAXBLists: public interface JaxbList<T> { public abstract List<T> getList(); } And an base implementation: @XmlRootElement(name="list") public class JaxbBaseList<T> implements JaxbList<T>{ protected List<T> list; public JaxbBaseList(){} public JaxbBaseList(List<T> list){ this.list=list; } @XmlElement(name="item" ) public List<T> getList(){ return list; } } As well as an implementation for a list of URIs: @XmlRootElement(name="uris") public class JaxbUriList2 extends JaxbBaseList<String> { public JaxbUriList2() { super(); } public JaxbUriList2(List<String> list){ super(list); } @Override @XmlElement(name="uri") public List<String> getList() { return list; } } And I'm using the List in the following way: public JaxbList<String> init(@QueryParam("amount") int amount){ List<String> entityList = new Vector<String>(); ... enityList.add("http://uri"); ... return new JaxbUriList2(entityList); } I thought the output should be: <uris> <uri> http://uri </uri> ... </uris> But it is something like this: <uris> <item xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:string"> http://uri </item> ... <uri> http://uri </uri> ... </uris> I think it has something to do with the inheritance, but I don't get it... What's the problem? - How can I fix it? Thanks in advance!

  • Landscape orientation for UITabBarController?

    - by gingersnap
    The UITabBarController does not allow landscape orientation. So I used a subclass of UITabBarContoller (called RotatingTabBarController). Its sole purpose it to allow rotation by returning YES to shouldAutorotateToInterfaceOrientation call. The problem is that when you rotate the iPhone in simulator it gives the following malloc error. malloc: *** error for object 0x3888000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I am using 3.0 SDK with Xcode 3.2 on Snow Leopard. I set a breakpoint in malloc_error_break but I can not trace it back to my code. Is there something I can do to make this error go away? Here is the RotatingTabBarController class: #import <UIKit/UIKit.h> @interface RotatingTabBarController : UITabBarController { } @end @implementation RotatingTabBarController -(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation { return YES; } @end Update: I tried the same with a category.

  • Synchronizing audio and video using MP4Box / ffmpeg to concatenate files

    - by jdl2003
    I have two H.264 encoded MPEG-4 files that I need to concatenate. I have been using MP4Box for this task by first ensuring the files are encoded identically (even went so far as to compare output from h264_parse on their video tracks) and then concatenating with this command: MP4Box -cat file1.mp4 -cat file2.mp4 output_file.mp4 This works and the output file is playable, but on playback in Quicktime or VLC the second video's audio starts too soon, making the entire second part of the concatenated file out of sync. I have tried reencoding the output through ffmpeg with -vcodec copy and -acodec copy but the sync issue persists. I have also tried converting to MPEG-2 format first, concatenating with a simple cat file1.mpg file2.mpg > output.mpg and reencoding the result with ffmpeg. This was even worse. I know that I can pass commands to MP4Box to adjust the start time of the audio track, but I am trying to do this programmatically for any input video (in the same encoding of course). I am looking for possible solutions that would not require human intervention / manual adjustments. Or, at least, an understanding of what is happening to make the second part of the concatenated video go out of sync.

  • File sharing service with an API?

    - by zoul
    Hello! Is there a file sharing service akin to Dropbox or SugarSync that would offer an API? I would like to add a file sharing service to a website, but the full Dropbox interface is still too complicated for my users, so that I’d like an API to build a dead-simple list of files integrated to the website. There is a Dropbox API project on Google Code, but it seems to be dead. PS: Extra points if the service has a free plan.

  • Panels-style UI for arbitrary CCK fields?

    - by ceejayoz
    I have a Drupal content type that has unlimited photo, textbox, and external link CCK fields, but while fields themselves can be reordered via drag-drop (i.e. photo B before photo A), I can't arbitrarily order amongst fields (i.e. photo B, link A, photo A, text A, link B). Panels is awesome, with its drag and drop, and just what I'm looking for interface-wise. Has anyone seen a Panels-style UI for ordering arbitrary collections of disparate CCK fields?

  • Best ways to teach a beginner to program?

    - by Justin Standard
    Original Question I am currently engaged in teaching my brother to program. He is a total beginner, but very smart. (And he actually wants to learn). I've noticed that some of our sessions have gotten bogged down in minor details, and I don't feel I've been very organized. (But the answers to this post have helped a lot.) What can I do better to teach him effectively? Is there a logical order that I can use to run through concept by concept? Are there complexities I should avoid till later?

  • Application Architecture using WCF and System.AddIn

    - by Silverhalide
    A little background -- we're designing an application that uses a client/server architecture consisting of: A server which loads server-side modules, potentially developed by other teams. A client which loads corresponding client-side modules (also potentially developed by those other teams; each client module corresponds with a server module). The client side communicates with the server side for general coordination, and as well as module specific tasks. (At this point, I think that means client talks to server, client modules talk to server modules.) Environment is .NET 3.5, and client side is WPF. The deployment scenario introduces the potential to upgrade the server, any server-side module, the client, and any client-side module independently. However, being able to "work" using mismatched versions is required. I'm therefore concerned about versioning issues. My thinking so far: A Windows Service for the server. Using System.AddIn for the server to load and communicate with the server modules will give us the greatest flexibility in terms of version compatability between server and server modules. The server and each server module vend WCF services for communication to the client side; communication between the server and a server module, or between two server modules use the AddIn contracts. (One advantage of this is that a module can expose a different interface within the server and outside it.) Similarly, the client uses System.AddIn to find, load, and communicate with the client modules. Client communications with client modules is via the AddIn interface; communications from the client and from client modules to the server side are via WCF. For maximum resilience, each module will run in a separate app-domain. In general, the system has modest performance requirements, so marshalling and crossing process boundaries is not expected to be a performance concern. (Performance requirement is basically summed up by: don't get in the way of the other parts of the system not described here.) My questions are around the idea of having two different communication and versioning models to work with which will be an added burden on our developers. System.AddIn seems quite powerful, but also a little unwieldly. (I'm also unsure of Microsoft's commitment to it in the future.) On the other hand, I'm not thrilled with WCF's versioning capabilities. I have a feeling that it would be possible to implement the System.AddIn view/adapter/contract system within WCF, but being fairly new to both technologies, I would have no idea of where to start.
