I am trying to use a web service as part of a dataflow task in SSIS. Right now i have a script task within a data flow with a web service reference.
What the task has to ultimately do is: collect all postal codes from an inernal database > use the web service i created to get the lay/long of thos postal codes > export the lat/long to a table.
As i said before i have the scrip set up and looks to be working, but when i go to execute the package i get an CannotCreateUserComponentException error.
Any help on this would be awesome, or another approach to it? I am new to the web services in SSIS so this is the best solution i could come up with.
Edit:
Right now the script is accepting the postal code from an OLE DB Source and will ouput a string in for format of "lat,long" (presumably). The web Service was created by someone within the company and has one method called FindCoordinates which takes in a string value (Postal code)(which i think calls the google geocode xml, not exactly sure what he did). Here is the code that is currently in my script:
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using SC_6c1b642acd544cd5b01c032b6f8dfd03.csproj.MyService;
using System.Xml;
using System.Web.Services;
[WebService(Namespace = "http://microsoft.com/webservices/")]
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
public override void PreExecute()
{
base.PreExecute();
/*
Add your code here for preprocessing or remove if not needed
*/
}
public override void PostExecute()
{
base.PostExecute();
/*
Add your code here for postprocessing or remove if not needed
You can set read/write variables here, for example:
Variables.MyIntVar = 100
*/
}
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
String postal = Row.PostalCode;
Service service = new Service();
Row.LatLong = service.FindCoordinates(postal);
}
}
Hope this help.

I have recently used Java Spring to create REST services. In it, there were annotations for binding each specific function to a different REST query. Lets not go too technical here, as a psuedo, it was like this:
/** list records */
#bind("/list", WebMethod.GET)
List<Record> getRecords()
{
}
/** get record */
#bind("/record", WebMethod.GET)
Record getRecord()
{
}
/** add record */
#bind("/record", WebMethod.POST)
void addRecord()
{
}
Now I am given a tesk to perform a REST with Casablanca SDK in C++, but in every tutorial I checked covers a single GET or POST request. Is it possible to bind multpile requests to custom targets similar to Spring in Casablanca SDK?
You can make a single get function where you capture all get requests, then just get the path from the query and use a switch to call different functions to process the request for that path.
I have added my web service Url to my application through the steps of "Add Web Reference" with the name of "SOAPNyd" in Xamarin Studio
Now I need to connect my web Methods, I see my web referenced methods under Web Service folder but can not connect to them and need know how to call , use my methods.
Could anyone show me one example with while loop to write down its all data to the Console please. Thank you.
here is one of my methods which returns all brands that I have at Data Base first value is empty second value is my pasword dont worry about parameters
public string getMarkalarlist(string s, string key) {
getMarkalarlistRequest1 inValue = new getMarkalarlistRequest1();
inValue.s = s;
inValue.key = key;
getMarkalarlistResponse1 retVal = ((WebDBServicesHttpGet)(this)).getMarkalarlist(inValue);
return retVal.#string;
}

i wanted to know what is the best approach to save WCF endpoints information in the config file for different environments(DEV,TEST,PRE-PROD, PROD).
i am familiar with 1 way of doing this - 1. Maintain different config files(for each env) and deploy them accordingly.
Can someone please suggest the best way to do this ??
You can configure the endpoint at runtime with endpointbehaviors. In this behaviors you can get the machinename for example. Depending on the machinename you could set yout endpointaddress for your endpoint, and then start the service.
Here is a link : https://msdn.microsoft.com/en-us/library/vstudio/ms730137%28v=vs.100%29.aspx
EDIT:
So you write:
class CustomEndpointBehavior : IEndpointBehavior{
public void Validate(ServiceEndpoint endpoint)
{
// get here the address and rewrite it dependig on the machinemane e.g.
// remember to set the new address to the endpoint!
}
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
}
}
And in the class where you start the service, you need to set the CustomEndpointBehavior to the serviceHost, like:
serviceHost.Description.Behaviors.Add(new CustomEndpointBehavior());
I think this is the link. Create multiple configuration and then use pre build event to copy it. http://www.hanselman.com/blog/ManagingMultipleConfigurationFileEnvironmentsWithPreBuildEvents.aspx
In you have visual studio 2010 and above then it will be able to merge the config. https://msdn.microsoft.com/en-us/library/dd465326(v=vs.110).aspx
Goal:
Retrieve data from Dynamics CRM 2011 to my database from SQL server R2 by using webservice through integration services (SSIS). Webservice needed to be located inside of SSIS. Gonna use the data for data warehouse.
Problem:
How do I do it?
We only write to Dynamics so I can't address the specific method name but the general idea below should get you started.
Assumptions
Two variables have been defined in your package and they are passed to the script component as ReadOnlyVariables: CrmOrganizationName, CrmWebServiceUrl.
A script component has been added to the dataflow as a Source component. On the Inputs and Outputs tab, an appropriate number of columns have been added to Output 0 (or whatever you define your output collection as) with appropriate data types.
Inside the script, add a web reference to your CRM instance. This code assumes it's called CrmSdk.
using System;
using System.Data;
using System.Data.SqlClient;
using System.Windows.Forms;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
// web reference
using CrmSdk;
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
public override void CreateNewOutputRows()
{
// Get a reference to the CRM SDK
CrmSdk.CrmService CrmService = new CrmSdk.CrmService();
// An Authentication Token is required because CRM requires an OrganizationName
// to identify the Organization to be used
CrmSdk.CrmAuthenticationToken token = new CrmSdk.CrmAuthenticationToken();
token.AuthenticationType = 0;
token.OrganizationName = this.Variables.CrmOrganizationName;
CrmService.CrmAuthenticationTokenValue = token;
// Use default credentials
CrmService.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Get the web service url from the config file
CrmService.Url = this.Variables.CrmWebServiceUrl;
//////////////////////////////////////////////////
// This code is approximate
// Use the appropriate service call to get retrieve
// data and then enumerate through it. For each
// row encountered, call the AddRow() method for
// your buffer and then populate fields. Be wary
// of NULLs
//////////////////////////////////////////////////
foreach (CrmSdk.entity person in CrmService.Get())
{
Output0Buffer.AddRow();
Output0Buffer.FirstName = person.FirstName;
Output0Buffer.LastName = person.LastName;
}
}
}
Caveats
There is no error handling, checks for nulls or anything elegant. The service should probably have been defined with the using statement, etc, etc, etc. It should provide an appropriate starting point for understanding how to consume a web service and load data into the pipeline.
The easiest solution for your requirement is to use a third-party library for SSIS. The commercial COZYROC SSIS+ library includes Dynamics CRM adapters, which support all deployment models: Premise, Live, Hosted, Federation, Office 365.
I am working on an ASMX web service; trying to create a method that will download a document from a server and show the document in the browser (the calling .aspx web page). My service builds without error but I get the following error when I try to "Add Web Reference" in my Proxy class project:
System.Web.HttpResponse cannot be serialized because it does not have a parameterless constructor.
Here is a snippet of the code in .ASMX file:
public class FileService : System.Web.Services.WebService
{
[WebMethod]
public void DownloadDocument(string URI, HttpResponse httpResponse)
{
int DownloadChunkSize = (int)Properties.Settings.Default.DownloadChunkSize;
// some more code here....
using (httpResponse.OutputStream)
{
// more code here...
}
}
}
I see I am confused about how to send back an HttpResponse from a web service to a requesting web page. Could someone please give me a tip on how to do this? Thanks.
You should look into web handlers (.ashx). They are perfect for what you are trying to achieve.
For example:
public class Download : IHttpHandler, IRequiresSessionState {
public void ProcessRequest(HttpContext context) {
var pdfBytes = /* load the file here */
context.Response.ContentType = #"Application/pdf";
context.Response.BinaryWrite(pdfBytes);
context.Response.End();
}
}
UPDATE:
An ashx handler is actually a replacement to aspx. Basically, it has no UI but still processes get / post requests just like an aspx page does. The point is to reduce the overhead generated by running a regular aspx page when all you need to do is return some simple content (like a file...) or perform a quick action.
The IRequiresSessionState interface allows you to use the SESSION object like any other page in your site can. If you don't need that, then leave it off.
This site has an interesting walk through on how to create one. Ignore Step 4 as you probably don't care about that.
Assuming that you have a regular page (aspx) that has a link to your document: The link in the aspx file would actually point directly to your ashx handler. for example:
Click Here
Then the code in the ProcessRequest method of the ashx handler would do whatever calls it needed (like talk to your DLL) to locate the document then stream it back to the browser through the context.Response.BinaryWrite method call.
That is not how standard ASMX web services work. If you want to make your own handler, or even use an ASPX page to deliver the doc, you are fine, but the standard ASMX web service method of doing this is to actually return the bits of the document as an encoded blob.
If you want to roll your own, consider this article:
http://msdn.microsoft.com/en-us/magazine/cc163879.aspx
The web smethod (from asmx) returns an object, which can be serialized.
You need to create your method like:
[WbeMethod]
public byte[] DownloadDocument(string URI)
Or if the content is some text - return string.
