Consuming Web Service Returned Date/time?
Sep 23, 2009
I have an interesting issue that a client reported It turns out that the desktop application they are using is changing the times returned by the web service to their local time so it looks like the data is off. We're in UTC-5 while they're in UTC-8 so 8:00 AM is returned to the GUI as 5:00 AM which is causing confusion. I've done this riddiculousness to get around it for now:
Code:
Dim intOffset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now).Hours
'Substract 1 if we're in daylight savings mode

I have a webservice being consumed in the WinForm application. I generated a web service wrapper and invoked a web service method asynchronously. I get following exception in my result completed event handler (the event is raised from within the web service wrapper class).
System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
---> System.Net.WebException: Unable to connect to the remote server

We have a web app that contains web methods. I want to invoke one of those methods from a console app. I am new at this but I wrote a console app, added a service reference and tried to code invoking it. If my web method is called "Transmit", I expected to see Transmit in the namespace I specified but instead I see "TransmitRequest", "TranmsitRequestBody", "TransmitResponse" and "TransmitResponseBody".What are these things?Have I done something wrong?How do I invoke the web method in the web app from the console app?

I have a WCF Service (with installer) that I have built and installed in Windows Services. Opened up Admin Tools, Services, and started the service without a problem. So now I'm beginning a new project (a simple Windows forms app). I want to consume my new WCF, but have no idea how. I can't seem to add a reference / add a service reference to it.

Wrote a 'webservice' with Netbeans wizard, runs on glassfish. I added a reference using the wsdl to my .NET client, VB if it makes any difference.The issue is a SoapHeaderException.
System.Web.Services.Protocols.SoapHeaderException: com/mysql/jdbc/Connection
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(
SoapClientMessage message, WebResponse response, Stream responseStream,
Boolean asyncCall)
[code]....
I've tried writing the string in a soap envelope, but still receive the same message. So passing a string is kaputt, as it should be; why would the WS know to parse a string, and simply instantiating and calling the method from the object as if it were local isn't working the way I think it does.

I am implementing a VB.NET desktop application which consumes a web service.
The web service implemented in Java and I currently using Tomcat on my localhost to host the web service.
The web service requires secure communication with the client and so I have followed instructions that outlined how to use Java's keytool.exe to create two .jks keystores (one for the client and one for the server) and then create two .cer certificates (one for the client and one for the server)
I have placed the keystores and certificates generate into the directory where the web service is expecting them (according to the instructions)
I have installed the certificates into TrustedPeople and have attempted to use the certificate by setting the ClientCredentials.ClientCertificates property like this:
myServiceProxy.ClientCredentials.ClientCertificate.SetCertificate(storeLocation.CurrentUser, StoreName.TrustedPeople, X509FindType.FindByIssuerName, "name")
I keep getting the following error message when I try to call any method:
An error was discovered processing the <wsse:Security> header
My problem is that I don't know how to use this in the VB.NET client application that is consuming the web service. I could be doing this completely wrong.

I am creating an XML web service that passes an array of custom types. In my consuming code I am referencing the code as a web reference which I have given the namespace MYWS. Now in code I am trying to assign the results of my web service call to an array of my type like so..[code]When I do this the complier complains, saying: "Value of 1 dimensional array of my.namespace.MyClass cannot be converted to 1 dimensional array of my. namespace. MYWS.MyClass because my.namespace.MYSW.MyClass is not derived from my.namespace.MyClass"Now I understand the message, the thing is they are the same class. The class is declared in my calling code by the web service references a dll from that project. How do I tell the compiler that these are the same type?

I'm currently working on a VB. Net web service calling another web service running in the mainframe. I was provided with the WSDL file and I generated a proxy class using wsdl.exe. Upon attempting to invoke the method of the mainframe web service using the proxy class, I encountered an exception saying "Conversion from SOAP failed" coming from a line of code in the generated proxy class.

I am creating a simple XML web service and have run into something I can't quite explain.My web service class has the following structure :
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
[code]....
Invoking my method using the built in VS web service test harness works fine. I created another project, in another solution, to test consuming the web service. I added a web reference to my project and set it so I could reference my web service by using "localWS". Then in the page load event of my consuming class I tried to instantiate an object of my web service:
Dim srv As New localWS.MyWS
But there was no "MyWS" type found. There is however a localWS.MyWSSoapClient class. When I use it I can invoke my web methods. My question is, why can't I create a straight up version of MyWS class? In the tutorials I'v read, and in the book I have, example consuming classes for .NET XML web services can instantiate objects of the web service class they are consuming. As a further test I added a new web form to my web service project and from there I was able to instantiate a MyWS class.

My wife wants me to create a cookbook application for her. I am going to use this as a learning experience (Otherwise, I would just buy her one).
The main requirements are that she can store her recipes thier ingredients and the steps involved in this SQL server driven program. She also wants to be able to view and print any recipe she chooses.
My question is how do I display the recipe in its complete form? I do not know how to use crystal reports, and automating Word is too time/resource consuming. So what are my options in VB 2008?

I am working with an XML web service using VB.NET, created using VS 2010. One of my web methods returns a collection(type that inherits from list) of custom objects. It's a simple return statement, it is my understanding that .NET handles most of the tricky protocol stuff as well as serializing/unserialzing of objects.
The issue is in my consuming application when I get the the return value of the web method that returns a custom collection I get an array of the custom objects. Is this normal behavior? It will be easy enough for me to take that array and insert it into a custom collection object but if I could I would like to skip this step.

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)
I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I have two functions written in VB.NET:
1) The first function (call it GetValues()) returns values in a SQL database as a list via a stored proc. One of the fields is DateTimeSubmitted. All of this data is displayed on my webpage using a repeater control. It works fine.
2) The second function (call it NiceDate()) I created to change the DateTimeSubmitted to a nice date such as "one minute ago" or "yesterday".
My problem is I have no idea which is the best part of the process to do the conversion (at point of data extraction or in pageload etc.) or in fact how to do the conversion.

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
