  • Webservice works with SoapSonar but not with Visual Studio Winform

    - by Rebol Tutorial
    I have generated a wsdl file with Visual Studio which is here; http://reboltutorial.com/webservices/discordian.wsdl Implementation is a cgi instead of a .net framework program but that should not matter as it is the purposes of webservices. I tested it successfully with SoapSonar: But under Visual Studio it fails with this code: private void button1_Click(object sender, EventArgs e) { RebolTutorial.ServiceSoapClient Discordian = new RebolTutorial.ServiceSoapClient("ServiceSoap"); int year = int.Parse(this.year.Text); int month = int.Parse(this.month.Text); int day = int.Parse(this.day.Text); response.Text = Discordian.Discordian(year,month,day); } Any reason you can see ? Thanks.

  • C# - Screenshot of process under Windows Service

    - by Jonathan.Peppers
    We have to run a process from a windows service and get a screenshot from it. We tried the BitBlt and PrintWindow Win32 calls, but both give blank (black) bitmaps. If we run our code from a normal user process, it works just fine. Is this something that is even possible? Or could there be another method to try? Things we tried: Windows service running as Local System, runs process as Local System - screenshot fails Windows service running as Administrator, runs process as Administrator - screenshot fails. Windows application running as user XYZ, runs a process as XYZ - screenshot works with both BitBlt or PrintWindow. Tried checking "Allow service to interact with desktop" from Local System We also noticed that PrintWindow works better for our case, it works if the window is behind another window. For other requirements, both the parent and child processes must be under the same user. We can't really use impersonation from one process to another.

  • C# code to GZip and upload a string to Amazon S3

    - by BigJoe714
    Hello. I currently use the following code to retrieve and decompress string data from Amazon C#: GetObjectRequest getObjectRequest = new GetObjectRequest().WithBucketName(bucketName).WithKey(key); using (S3Response getObjectResponse = client.GetObject(getObjectRequest)) { using (Stream s = getObjectResponse.ResponseStream) { using (GZipStream gzipStream = new GZipStream(s, CompressionMode.Decompress)) { StreamReader Reader = new StreamReader(gzipStream, Encoding.Default); string Html = Reader.ReadToEnd(); parseFile(Html); } } } I want to reverse this code so that I can compress and upload string data to S3 without being written to disk. I tried the following, but I am getting an Exception: using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(AWSAccessKeyID, AWSSecretAccessKeyID)) { string awsPath = AWSS3PrefixPath + "/" + keyName+ ".htm.gz"; byte[] buffer = Encoding.UTF8.GetBytes(content); using (MemoryStream ms = new MemoryStream()) { using (GZipStream zip = new GZipStream(ms, CompressionMode.Compress)) { zip.Write(buffer, 0, buffer.Length); PutObjectRequest request = new PutObjectRequest(); request.InputStream = ms; request.Key = awsPath; request.BucketName = AWSS3BuckenName; using (S3Response putResponse = client.PutObject(request)) { //process response } } } } The exception I am getting is: Cannot access a closed Stream. What am I doing wrong?

  • WSDL Object model

    - by Swaroop
    I'm using the WSDL object model (WOM) along with XSOM for a project of mine. The WOM gives me a way to drill down and look at messages and the message types which are element declarations. However, I am unable to find a way to parse the simple and complex types. The APIs are tricky. There seems to be some kind of a connection between WOM and XSOM. I'd really appreciate it if you could tell me how I can parse the simple and the complex types in my .wsdl file.

  • CreateProcessAsUser doesn't draw the GUI

    - by pavel.tuzov
    Hi, I have a windows service running under "SYSTEM" account that checks if a specific application is running for each logged in user. If the application is not running, the service starts it (under corresponding user name). I'm trying to accomplish my goal using CreateProcessAsUser(). The service does start the application under corresponding user name, but the GUI is not drawn. (Yes, I'm making sure that "Allow service to interact with desktop" check box is enabled). System: XP SP3, labguage: C# Here is some code that might be of interest: PROCESS_INFORMATION processInfo = new PROCESS_INFORMATION(); startInfo.cb = Marshal.SizeOf(startInfo); startInfo.lpDesktop = "winsta0\\default"; bResult = Win32.CreateProcessAsUser(hToken, null, strCommand, IntPtr.Zero, IntPtr.Zero, false, 0, IntPtr.Zero, null, ref startInfo, out processInfo); As far as I understand, setting startInfo.lpDesktop = "winsta0\default"; should have used the desktop of corresponding user. Even contrary to what is stated here: http://support.microsoft.com/kb/165194, I tried setting lpDesktop to null, or not setting it at all, both giving the same result: process was started in the name of expected user and I could see a part of window's title bar. The "invisible" window intercepts mouse click events, handles them as expected. It just doesn't draw itself. Is anyone familiar with such a problem and knows what am I doing wrong?

  • Running msiexec from a service (Local System account)

    - by Jarrod
    We are working on an update system for our software. The updater should in the background as a service, and when an update is available, downloads and installs it. We need the service to install the update since the msi requires elevation to run, but some of our clients will be restricted users. The MSI is a WIX MSI and does a Major Upgrade when run. The problem is, the update does not seem to work when ran from our service. I can see msiexec run, and it returns successfully, but seems to make no changes to the system. The same command, when run from my user account works as expected. Is there some caveat to running msiexec from a Local System service? We are simply doing: System.Diagnostics.Process.Start("msiexec.exe", arguments);

  • Convert xml as string

    - by hakish
    i have a scenario where in i need to send an xml as a tag content in a SOAP request message to a webservice for example <arg_1><xml version="1.0" encoding="UTF-8"?><sometag><somemoretag>abcd</somemoretag></sometag></arg_1></code> arg_1 happens to be an String parameter to a webservice. So i bring in a CDATA section for this <arg_1><![CDATA[<xml version="1.0" encoding="UTF-8"?><sometag><somemoretag>abcd</somemoretag></sometag>]]></arg_1> But this keeps throwing me an exception org.xml.sax.SAXException: WSWS3084E: Error: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. Message being parsed: I keep getting this exception. Has anyone seen this before??

  • SSRS 2008 - How to hide the plus icon in a group visibility toggle cell

    - by Daniel Coffman
    I have a report that shows or hides columns in a group based on a header cell. SSRS makes this pretty easy and is kind enough to place a little plus/minus icon in the toggling cell. I want to HIDE this plus/minus icon when there is only one column of data in the subgroup, because it shows that one column by default so expanding the group doesn't do anything. This really only applies to one specific group, because all the others always have more than one column of data, so a way to hide only the icon for a specific group would be fine. JavaScript won't work (I don't think) because the client ID of the plus/minus image is generated by the report and changes with each generation. see this image for more clarity: http://imgur.com/vqaQA.png

  • Can't get JAX-WS binding customization to work

    - by Florian
    Hi! I'm trying to resolve a name clash in a wsdl2java mapping with CXF 2.2.6 The relevant wsdl snippets are: <types>... <xs:schema... <xs:element name="GetBPK"> <xs:complexType> <xs:sequence> <xs:element name="PersonInfo" type="szr:PersonInfoType" /> <xs:element name="BereichsKennung" type="xs:string" /> <xs:element name="VKZ" type="xs:string" /> <xs:element name="Target" type="szr:FremdBPKRequestType" minOccurs="0" maxOccurs="unbounded" /> <xs:element name="ListMultiplePersons" type="xs:boolean" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="GetBPKResponse"> <xs:complexType> <xs:sequence> <xs:element name="GetBPKReturn" type="xs:string" minOccurs="0" /> <xs:element name="FremdBPK" type="szr:FremdBPKType" minOccurs="0" maxOccurs="unbounded" /> <xs:element name="PersonInfo" type="szr:PersonInfoType" minOccurs="0" maxOccurs="5" /> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </types> <message name="GetBPKRequest"> <part name="parameters" element="szr:GetBPK" /> </message> <message name="GetBPKResponse"> <part name="parameters" element="szr:GetBPKResponse" /> </message> <binding... <operation name="GetBPK"> <wsdlsoap:operation soapAction="" /> <input name="GetBPKRequest"> <wsdlsoap:header message="szr:Header" part="SecurityHeader" use="literal" /> <wsdlsoap:body use="literal" /> </input> <output name="GetBPKResponse"> <wsdlsoap:body use="literal" /> </output> <fault name="SZRException"> <wsdlsoap:fault use="literal" name="SZRException" /> </fault> </operation> As you can see, the GetBPK operation takes a GetBPK as input and returns a GetBPKResponse as an output. Each element of both the GetBPK, as well as the GetBPKResponse type would be mapped to a method parameter in Java. Unfortunately both GetBPK, as well as the GetBPKResponse have an element with the name "PersonInfo", which results in a name clash. I'm trying to resolve that using a binding customization: <jaxws:bindings wsdlLocation="SZ2-aktuell.wsdl" xmlns:jaxws="http://java.sun.com/xml/ns/jaxws" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:szr="urn:SZRServices"> <jaxws:bindings node="wsdl:definitions/wsdl:portType[@name='SZR']/wsdl:operation[@name='GetBPK']"> <!-- See page 116 of the JAX-WS specification version 2.2 from 10, Dec 2009 --> <jaxws:parameter part="wsdl:definitions/wsdl:message[@name='GetBPKResponse']/wsdl:part[@name='parameters']" childElementName="szr:PersonInfoType" name="PersonInfoParam" /> </jaxws:bindings> </jaxws:bindings> and call wsdl2java with the -b parameter. Unforunately, I still get the message: WSDLToJava Error: Parameter: personInfo already exists for method getBPK but of type at.enno.egovds.szr.PersonInfoType instead of java.util.List<at.enno.egovds.szr.PersonInfoType>. Use a JAXWS/JAXB binding customization to rename the parameter. I have tried several variants of the binding customization, and searched Google for hours, but unfortunately I cannot find a solution to my problem. I suspenct that the childElementName attribute is wrong, but I can't find an example of what would have to be set to make it work. Thanks in advance!

  • WCF Security in a Windows Service

    - by Alphonso
    I have a WCF service which can run as Console App and a Windows Service. I have recently copied the console app up to a W2K3 server with the following security settings: <wsHttpBinding> <binding name="ServiceBinding_Security" transactionFlow="true" > <security mode="TransportWithMessageCredential" > <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Common.CustomUserNameValidator, Common" /> </serviceCredentials> Security works fine with no problems. I have exactly the same code, but running in a windows service and I get the following error when I try to call any of the methods from a client: System.ServiceModel.Security.MessageSecurityException was unhandled Message="An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." Source="mscorlib" StackTrace: Server stack trace: at System.ServiceModel.Channels.SecurityChannelFactory`1.SecurityRequestChannel.ProcessReply(Message reply, SecurityProtocolCorrelationState correlationState, TimeSpan timeout) ...... (lots of stacktrace info - not very useful) InnerException: System.ServiceModel.FaultException Message="An error occurred when verifying security for the message." The exception tells me nothing. I'm assuming that it has something to do with acces to system resources from the Windows Service. I've tried running it under the same account as the console app, but no luck. Does anyone have any ideas?

  • Need help understanding Generics, How To Abstract Types Question.

    - by kmacmahon
    I could use some really good links that explain Generics and how to use them. But I also have a very specific question, relater to working on a current project. Given this class constructor: public class SecuredDomainViewModel<TDomainContext, TEntity> : DomainViewModel<TDomainContext, TEntity> where TDomainContext : DomainContext, new() where TEntity : Entity, new() And its creation this way: DomainViewModel d; d = new SecuredDomainViewModel<MyContext, MyEntityType>(this.context, selectedProtectedItem); Assuming I have 20 EntityTypes within MyContext, is there any easier way to call the constructor without a large switch statement? Also, since d is DomainViewModel and I want to access methods for SecuredDomainViewModel, it seems I need to do this: if (((SecuredDomainViewModel<MyContext, MyEntityType>)d).IsBusy) But again "MyEntityType" could actually be one of 20 types. Is there anyway to write these types of statements where MyEntityType is returned from some sort of Reflection?

  • should I use Entity Framework instead of raw ADO.NET

    - by user110182
    I am new to CSLA and Entity Framework. I am creating a new CSLA / Silverlight application that will replace a 12 year old Win32 C++ system. The old system uses a custom DCOM business object library and uses ODBC to get to SQL Server. The new system will not immediately replace the old system -- they must coexist against the same database for years to come. At first I thought EF was the way to go since it is the latest and greatest. After making a small EF model and only 2 CSLA editable root objects (I will eventually have hundreds of objects as my DB has 800+ tables) I am seriously questioning the use of EF. In the current system I have the need many times to do fine detail performance tuning of the queries which I can do because of 100% control of generated SQL. But it seems in EF that so much happens behind the scenes that I lose that control. Article like http://toomanylayers.blogspot.com/2009/01/entity-framework-and-linq-to-sql.html don't help my impression of EF. People seem to like EF because of LINQ to EF but since my criteria is passed between client and server as criteria object it seems like I could build queries just as easily without LINQ. I understand in WCF RIA that there is query projection (or something like that) where I can do client side LINQ which does move to the server before translation into actual SQL so in that case I can see the benefit of EF, but not in CSLA. If I use raw ADO.NET, will I regret my decision 5 years from now? Has anyone else made this choice recently and which way did you go?

  • how to handle exceptions in ejb 3 based soap webservice

    - by Alexandre GUIDET
    Hi, I am currently developing an EJB3 based SOAP webservice and I wonder what are the best practices to handles uncatched exceptions and return a well formated SOAP response to the client. example: @WebMethod public SomeResponse processSomeService( @WebParam(name = "someParameters") SomeParameters someParameters) { // the EJB do something with the parameters // and retrieve a response fot the client SomeResponse theResponse = this.doSomething(someParameters); return theResponse; } Do I have to catch generic exception like: @WebMethod public SomeResponse processSomeService( @WebParam(name = "someParameters") SomeParameters someParameters) { // the EJB do something with the parameters // and retrieve a response to return to the client try { SomeResponse theResponse = this.doSomething(someParameters); } catch (Exception ex) { // log the exception logger.log(Level.SEVERE, "something is going wrong {0}", ex.getMessage()); // get a generic error response not to let the // technical reason going to the client SomeResponse theResponse = SomeResponse.createError(); } return theResponse; } Is there some kind of "best practice" in order to achieve this ? Thank you

  • Application threads vs Service threads

    - by zerayaqob
    What are the advantages/disadvantages in placing a lengthy network access code in a thread in an activity or a thread in a service? How would it affect the application? I am writing a streaming audio player and from what I've read so far putting the code in a service will still end up blocking the application so a new thread is needed, does anyone know if it makes more sense to put this piece of code in a service. Thanks

    I have a .Net webserivce that accepts XML in string format. XML String sent into the webserivce can represent any Object in the system. I need to check the first node to figure out what object to deserialize the XML string. For this I will have to load the XML into an XMLDocument (Don't want to use RegEx or string compare). I am wondering if there is a way to Deserialize the XMLDocument/XMLNode rather that deserializing the string to save some performance? Is there going to be any performance benefit serializing the XMLNode rather that the string? Method to Load XMLDocument public void LoadFromString(String s) { m_XmlDoc = new XmlDocument(); m_XmlDoc.LoadXml(s); } Thanks

  • Preserving Language across inline Calculated Members in SSAS

    - by Tullo
    Problem: I need to retrieve the language of a given cell from the cube. The cell is defined by code-generated MDX, which can have an arbitrary level of indirection as far as calculated members and sets go (defined in the WITH clause). SSAS appears to ignore the Language of the specified members when you declare a calculated member inline in the query. Example: The cube's default locale is 1033 (en-US) The cube contains a Calculated Measure called [Net Pounds] which is defined as [Net Amt], language=2057 (en-GB) The query requests this measure alongside an inline calculated measure which is simply an alias to the [Net Pounds] When used directly, the measure is formatted in the en-GB locale, but when aliased, the measure falls back to using the cube default of en-US. Here's what the query looks like: WITH MEMBER [Measures].[Pounds Indirect] AS [Measures].[Net Pounds] SELECT { [Measures].[Pounds Indirect], [Measures].[Net Pounds] } ON AXIS (0) FROM [Cube] CELL PROPERTIES language, value, formatted_value The query returns the expected two cells, but only uses the [Net Pounds] locale when used directly. Is there an option or switch somewhere in SSAS that will allow locale information to be visible in calculated members? I realise that it is possible to declare the inline calculated member in a particular locale, but this would involve extracting the locale from the tuple first, which (since the cube's member is isolated in the application's query schema) is unknown.

  • Problem with openssl_get_privatekey returning false

    - by Joe Corkery
    I am trying to generate a signed url for Amazon's CloudFront service but am running into problems in that the openssl_get_privatekey function appears to be returning false and I can't quite figure out why. Here is the code (PHP) that I am using: $priv_key = file_get_contents(path_to_my_pem_file); $priv_keyid = openssl_get_privatekey($privkey); Unfortunately, everytime I try this openssl_get_privatekey fails silently and I run into errors when I try to sign with openssl_sign later on. I've tried printing out the contents of $priv_key after it has been read in and it appears to be correct. I'm running this on RHEL 5.4 using PHP 5.2.13. I've confirmed that file pem file is readable and I've also run dos2unix on it just in case (didn't work before or after). Any thoughts would be greatly appreciated as I am relatively new to both PHP and openssl.

  • Windows Service Setup issue removing the windows service

    - by Geykel
    I'm doing a windows service setup project on VS2008, it has a custom action for setting app.config values. The setup work fine installing the service and setting the app.config values but when I try to uninstall the service, it removes the files but keep the service registered, so I can install it again using the setup, I need to use "sc delete " in the vs command prompt to proper remove the service... anyone have any idea which could be the issue here? Thank you.
