Web Service Export Parameters missing when consumed by Visual Studio 2005

I am using Visual Studio 2005 (2.0 framework) to consume bespoke SAP Web Services (SAP 4.7) however some of the export parameters are missing. I have tested the SAP web services with various XML tools and they all work perfectly.
Is there anything I can do to enable Visual Studio to genarate the correct proxy?
Many thanks for any tips.

This isn't going to work as well as I had thought.
That is correct that the Name and Value fields come back as XmlNode arrays. Each XmlNode array contains two XmlNode objects (or one if you received a null value from the db). One object contains the atrributes and one contains the value. I had planned on going into the ColumnValueType Value field and pulling the text of the 2nd XmlNode object.
Now here is the problem:
For every column you select you get a ColumnValueType object. Rather than being contained in some type of "Row" parent object, each column sits in the root of your results. For example, in the query I am using I am asking for the AlertingName and DnOrPattern columns of the NumPlan table. My results come back like this (simplified):
John Doe
With the data in this format, I can't just do a foreach loop and iterate over the ColumnValueType objects.

  • Creating a Web Service Proxy for a transaction with Microsoft Visual Studio

    Hi experts out there,
    I have created a simple transaction which I'd like to call as a webservice. Getting the WSDL from an authenticated browser (from which I started the xMII Workbench) works fine. But when I try to create a Web Reference within my Visual Studio project I only get the following output:
    "XacuteWS" Description
    Xacute ( LoginName As string ,  LoginPassword As string ,  InputParams As InputParams ) As Rowset
    I think this is because my visual studio is not authenticated with the xMII server. So is there any way to achieve this? I have to find a way to generate a .NET proxy for out xMII web services because otherwise it would be too complicated to use the web services from within our .NET applications.
    Thanks in advance for any hint on this topic!

    Two comments:
    1) The generated proxy looks correct.  If you explore the generated code for the InputParams object and the Rowset object, they should represent the incoming and outgoing data structures for your transaction.  If not, and if you are returning an XML property type from the transaction, be sure that you have used the "Assign Reference Document" technique to tell MII what the structure of your outgoing document is (there are a few other discussion threads on that topic).
    2) Personally, I find it much easier to consume MII services from .NET code using a URL-based technique instead of a SOAP based technique.  Invoke the "Runner" servlet (see the documentation) and you'll get an XML document back, that will always be in the MII Rowsets/Rowset/Row format.  Also, it is "self describing" because it includes Column metadata information.  It is very trivial to load this into a .NET XmlDocument object and parse/process it.  In fact, doing a similar approach, I've been able to make MII services appear as ADO.NET tables/stored procedures to .NET code.

  • Barcode export to PDF - Crystal Reports for Visual Studio 2005

    Hi, we have a report that includes a barcode.  We can print the report OK, but when we export to PDF the barcode is missing.  Is there a work around for this?  We have to have the PDF of the report for archive purposes.  Thanks!

    Are you on SP1?
    Is this happening on your dev computer or after you deploy the app?
    Web or Win app?
    Provide more info on "missing"; you see empty space? Barcode shows up as alpha numeric text?

  • Missing Web Service Input Parameters

    I am creating a form on web services. The source of the webservice is BEPL.
    When I register the webservice, I see the in and the out parameters.
    Operation Name     process
    Input Parameters
    Operation     Parameter Name     Parameter Type
    process     Data_source     string
         Data_URI     string
         Token     string
    But when I continue to create a form on the service, the next screen shows this message:

    no data found
    Any idea what may be going on here?

    Are you sure it's a public webservice or that you put in the right username/password?
    Also if you call the webservice just from an url, does that work for you?

  • EJB Web Service Interface parameters name changed

    Hi, all,
    I create a simple Session EJB 3.0 with Web Service interface in Jdeveloper and I deployed it into the embedded OC4J server.
    The question is I found that the web service operator parameters is changed to "String_1" (actually the parameter in EJB method is String ss). And I found the WSDL file is also String_1.
    How to create the real parameter name in WSDL from EJB Web Service interface? Any help on that?
    Best Regards,

    if you do a lookup for the name "java:comp/env/ejb/queryProc" in the servlet, the deployment descriptor of your web-archive must contain an ejb-reference with the ref-name 'ejb/queryProc'.

    I think the problem may be that the SimpleServlet example uses an apt feature to generate a web.xml which will replace any web.xml you already have in the project (and lose any references etc you might have in it). To work around this problem first copy the necessary lines from the web.xml in the generates .war file - they should look something like this:
    <servlet-name>RESTBeans Application</servlet-name>
    <servlet-name>RESTBeans Application</servlet-name>
    Add these to your project web.xml, replacing any lines that look similar (the web.xml in the sample project has these lines that you'll need to replace:
    <!-- this is a comment -->
    Now you need to turn off automatic web.xml generation by adding <option key="noservlet"/> to the apt task option in build.xml (look for the apt child of the -pre-compile task in build.xml).
    Clean and rebuild and make sure that the web.xml in the generated .war file now matches the project web.xml file.

  • Missing controls when in resource manager of visual studio 2005

    I'm trying to port an application to Visual Studio 2005.  It uses GPIB and Serial controls. When I double-click on the
    dialog to bring it up to look at the controls, an error is displayed saying that the controls could not be instantiated, reinstall or register the
    controls and try again.  I have installed and have Measurement Studio in my Visual Studio 2005.  I know this is probably vague,
    but ANY help would be greatly appreciated!

    Hi KBr,
    I assume you were using the CWGPIB and CWSerial ActiveX controls right? What
    version of Visual Studio were you previously using (VS 6.0, .NET 2003)? Also
    what language were you programming in (C++, VB, etc) and what language are you
    in now (C++, VB.NET, C#)?
    Also what version of Measurement Studio did you purchase (Standard,
    Professional or Enterprise)? The reason I ask is that those CWGPIB and CWSerial
    ActiveX controls are legacy components and you will need the Measurement Studio
    for Visual Studio 6.0 support to have these components. This CD only comes with
    the Professional and Enterprise versions of Measurement Studio.
    My guess is that you only have the Standard Edition which doesn't come with the
    VS 6 support.
    If you are programming in .NET (C#, VB.NET), I highly
    recommend that you use the native .NET VISA and GPIB class libraries with
    Visual Basic .NET rather than the ActiveX controls. The .NET class libraries
    are more full featured, exhibit better performance, and should be much more
    natural to use in VB.NET or C# than the ActiveX controls.
    Hope this helps!

  • Dynamic Image Displays Blank When Using In Visual Studio Project

    I am trying to simply display a dynamic image in a report. I am using Crystal Reports XI Release 2.
    I have two different environments: Local via Progress where reports are called using Crystal Viewer ActiveX, and over the web where reports are called from Open Laszlo and Visual Studio project.
    The image is set to a blank image as default, and Graphic Location Forumla loads the image from the database (site.logo_location + site.logo_filename) which results in an image http:
    When I run the reports locally using the ActiveX control, it works just fine and displays the image.
    When I run over the web using OpenLaszlo, it displays a blank.
    We are using Visual Studio 2005, which is bundled with an older version of Crystal that doesn't support dynamic images.
    To address this, I loaded Crystal XI Release 2, which updated the version in Visual Studio and enabled the Graphic Location formula field on the dev machine.
    I verified the Graphic Location field was set correctly.
    This caused a Version error, so we loaded cr_net_2005_mm_mlb_x86.zip on server and specified the Version in web.Config.
    No errors now, but when I build and publish the code, the image still displays as blank.
                From Fiddler
                   GET http://www.vetinfo3.com/mdsol1/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_c5d6a923-293b-4f1e-8739-4e698f83b087.png
                   Creates C:\Documents and Settings\Curtis\Local Settings\Temporary Internet Files\Content.IE5\PWRUX2XW\CrystalImageHandler[1].png
                   Blank Image
    According to issues within Visual Studio, they say the fix to this is to add the <httpHandler> in web.Config, but it is already there; added when we add the viewer to the project:
    In web.Config I have some questions about this line:
          <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=11.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
    There are more service packs for Crystal XI Release 2:
    I have not loaded these yet, but the readme files do not indicate they fix any dynamic image issues.
    I am out of ideas on this; does anyone have any ideas?

    What about if you take OpenLaszlo out of the picture? E.g.; use one of our samples from here;
    I'd recommend vbnet_web_simplepreviewreport

  • Visual Studio 2005 crashes when referencing ALI 6.5 portal server API

    Visual Studio 2005 crashes when referencing ALI 6.5 portal server API
    We are building new portlets in .NET 2.0 to that access the ALI 6.5 server API and are experienceing the folowing scenario:
    I create a brand new project in Visual Studio (2005 with SP1 on Win2k3 R2 SP2) using the ALI Portal Project template that is provided with the application accelerator 1.1. This portlet will need to perform portal server searches so I begin by adding references to the following assemblies from C:\bea\alui\ptportal\6.5\bin\assemblies:
    I then type in something like below to start up the portal server objects.
    protected void Page_Load(object sender, EventArgs e)
    IOKContext context = OKConfigFactory.createInstance("C:\\bea\\alui\\settings\\", "portal");
    this.Response.Write("Portal Objects Initiallized");
    Some moments later Visual Studio will crash. It has happened before I have entered any code, after I have started typing code and on builds. It seems intermittent but usually occurs within a minute of interacting with this Visual Studio project. I actually managed to build once and have had success accessing this page in Explorer to validate the portal server objects are getting initialized and referenced correctly.
    I thought this was a problem with my personal development environment. So I tried this on other machines: another Win2k3 ALI 6.5 dev portal server and another server with Visual Studio 2005 that I installed the 6.5 portal on just for testing this. The exact behavior listed above is occurring on three development machines here (crashing devenv.exe when portal references are made or loading a project with portal references). Since this does not seem to be isolated to a single development machine, is there any course of action that anyone would suggest to help solve this?
    Troy Rackley

    It turns out that this is only a problem with Visual Studio using the ALI templates or creating any projects using the "New... Web site" functionality of 2005. I was a ble to create a C#... ASP.net Web Application project and add the references to the idk and the local portal server APIs manually without devenv.exe crashes.
    So, the work around I have found if your projects needs to access both the portal server API and the remote API is to create the project with:
    New... Project... Visual C#... ASP.NET Web Application
    and NOT
    New... Web Site... ASP.NET Web Site (or ALI Portlet Project)
    Anyone know why this is the case?

  • No images when deploying Crystal Reports for Visual Studio 2005

    CA Forum: Publishing
    Developed a ASP.Net web site that uses Crystal Reports for Visual Studio 2005, everything works fine locally.
    Following instructions from  http://support.businessobjects.com/downloads/merge_modules.asp#07 a deployment package has been created using CrystalDecisionsRedist2005_x86 merge module and the website has been installed.
    When it is deployed to a remote development server the report images are not displayed.  The report navigation works, it is the images that are not found when the report is displayed.
    Should the vs2005 key be entered some where on the remote server?

    Post Author: wcl

    Thnakyou very much for your quick reply.
    The directory has not been created by the merge module,  which folder should it be created in and what contetants should it have?
    an example of an image it can not find is "/aspnet_client/System_Web/2_0_50727/CrystalReportWebFormViewer3/images/toolbar/upd.gif",  so does the folder '/aspnet_client/System_Web/2_0_50727/CrystalReportWebFormViewer3' need setting up?

    Hi Experts,
    I am trying to open .xlsx file in script task of SSIS 2005. I am using the 32-bit AccessDatabaseEngine driver with the Connection string as "Provider= Microsoft.ACE.OLEDB.12.0; Data Source=xlsx file path; Extended Properties="Excel 12.0 Xml;

    My SQL server version is 2005 SP2 DE
    OS is Windows server 2003 EE SP2
    Could anyone please let me know what is the resolution for this error?
    Thanks and Regards,

    Hi Adesh,
    First, make sure the package runs in 32-bit runtime mode (set Run64BitRuntime property to False) because you are using the 32-bit ACE OLE DB Provider. If it is not the case, the issue may occur due to the corrupted drivers or registry keys. You can try to
    reinstall the 2007 Office System Driver: Data Connectivity Components as Arthur suggested.

  • Exporting to Microsoft Excel from a DataView Web Part consuming a Web Service with Parameters

    In Sharepoint Designer, I've developed a page displaying a DataView Web Part which consumes an XML Web Service with three parameters.  These parameters are passed in from a simple Form Web Part containing three input fields.  I am able to provide default values for the web service so the dataview is initially populated, and when I enter in new parameters, the web service goes back, grabs the requested data and displays in the dataview nice and slick.
    The problem I'm having is this: In Internet Explorer 7, when I right-click on the DataView Web Part and select Export to Microsoft Excel, Excel opens up, says "ExternalData_1: Getting Data..." and returns the data from the web service which applies to the default parameter values each and every time, regardless of whether I have changed the parameters on the web page, and contrary to what the DataView Web Part displays on the screen.
    Has anyone else run into this, and is there a solution to the problem?
