I created a WCF Service running as a console application. It is doing event listening for my workflow engine.The second application I am trying to do is a WinForm that can monitor the service and return me back the current states of the engine's workersI am able to connect to the service fine, and I verified that my service has values being set when I step through it... however when my monitor makes a call to the service, I am returning values as though it is not being run? (So default values, not current values
I am trying to return a structure from one of my web services. It throws up this error:

I am having some issues in attempting to display a recordset from my webservice. Currently my application involves a client feeding their values into my webservice.The webservice will then call a vb.net database class, which executes a SQL stored procedure, returns a recordset to the database class, and the class will pass the recordset back to the webservice, which will display it to the client in xml.
The problem I am having passing the recordset from the database class back to the webservice in a format that can be sent back to the client. I can't seem to convert the recordset to string format. Would it be better to have the record returned in XML format?
I am trying to populate a combo list box with the results of a web service. The web service returns a dataset with two columns. I want to display column one to the user and capture column two with the user selection of an item from the combox.right now I can display the first column and capture the selection.Not sure how to add the connection of column two, to the combo box and capture the selection
Code so far.... myDataSet1 = proxy3.listSuppLang() Dim x As Integer
I need to return an error message to the client, if they have entered invalid data when calling my web service. So if my code is: [code]Is there a way to display a more user friendly error message (such as a message box or just the words "Invalid Order ID")?
I have a Search web reference (from a Search Server 2010 express install) in a vb.net application that is utilizing the QueryService Class to search a production Sharepoint foundation 2010 site.At a previous point in time, we had created a proof of concept on an entirely test system that has since been turfed. From my recollection on this test system when documents were uploaded as a specific site content type (that inherits from document) and metadata was provided, we could search for specific metadata by making managed properties for each, and search results would be returned as documents (with the isdocument flag set to true). Viewing the document then became simple, as we could simply use the filename and path to display the stored file.Now we are developing a production system and we have encountered a new behavior, where these results now are returned as aspx results such as
[URL]
This of course makes it terribly difficult to locate and view the document, we can extract the Title which will then give us the name of the file with no extension, but that hardly helps, as the FileExtension data is aspx, not the documents file extension, so we don't have a full filename. We could display the page returned as a result, but would much prefer the document itself.
I've made a test document library, with just bare bones setup, (not using the site content type, or site columns) and uploaded some documents on the same site, and they are returned in the same fashion, so I don't believe the document library, or content type are the issue.
With a fairly limited understanding of both Sharepoint and Search Server, I don't know if this is a setup issue with the search service itself, with the site configuration, or with the querypacket I am sending. We also have a third party application (Knowledgelake) installed on the server that ties into sharepoint which could have changed configuration somewhere as well?
I don't think the query packet has changed since it was working in the proof of concept, other than the custom data column names. I will provide it here in case there is something glaringly obvious to an external reader.
i have this class that i'm calling from a telerik report. when debugging asp.net application the report shows the right results but when i deploy to IIS it just return the first row and not the SUM of the salary variable.

Is it possible to return more than one value from a function? Like two integers, or an integer and a boolean, or any other data type combination. I understand I could use a sub and set these values in a variable but I was wondering if I could avoid declaring more variables by using a function.
I'm making this game where there is an enemy that goes to the center of the form and grabs an object and brings it back to the side. I made a new class called enemy that makes the enemy. in the class there is a sub called start which the enemy goes to the center and brings the object back. when the enemy comes back with the object i want the integer lives to subtract 1 from it. so i put the
If Not Rect.IntersectsWith(Form1.ClientRectangle) Then Form1.Lives -= 1 End If
where Rect is the enemy's bounds. when ever rect is not intersecting with the forms bounds (which means when its off screen) lives should subtract 1, but it doesnt.
For some reason the Current Directory of my windows service is C:WindowsSystem32 and when I schedule my service I get this error Access is Denied.
In one of the blogs I saw this peice to change the current directory. But I am not sure where to place this code. System.IO.Directory.SetCurrentDirectory(System.AppDomain.CurrentDomain.BaseDirectory)

This is more of a conceptual question than anything.
I have a base class called "RawReader".
It sets up the framework for classes to inherit it and read in specific data systems.
For example, I want an app read in a known format of FoxPro database, a CSV file, or a SQL database (there is about 8 more formats currently), then transfer it over a webservice and create a SQL database from it.
I have everything working with CSV, FoxPro, Access, Excel, etc... Easy enough.
The classes that inherit RawReader, like RawCSV, RawFoxPro, RawAccess all return a struct that contains a dataset as one of the members. The dataset contains the data from the raw system. The webservice receives this struct and creates sql tables and loads the data into it. This has already been coded and works great.
My issue now comes to reading in SQL. Obviously, I could follow the same path, read the remote SQL DB into a dataset, transfer the dataset as above, etc... My "issue" comes in where I feel like it doesnt make much sense to transfer a SQL db to a dataset, transfer it through the webservice, and then try to programmatically recreate the SQL database. I feel like I lose a lot of the granular details from the SQL database (field sizes, extended info, etc..) It seems easier in practice to just create a backup of the database, convert it to a stream object and transfer the backup over to the webservice. But this is where the problem lies...
Since all of the classes inherit from the base class, they are set up to return a DataSet. The hack-ish way would be to just add a stream object to the return struct and in my webservice add other code to make a special case for SQL sources, but I was trying to avoid that.
Any thoughts on the "proper" way to go about something like this?
look at this class and say why it's just returning just the first row in the second query, the issue is that the Salary is showing the right value when debugging, but when deployed to IIS it's just returning the 1st row

Ok simply my code doesnt want to output the correct number. I'm working on the project euler probems to expand my knowledge in VB.net and the current question I am working on is asking to work with triangle numbers. while researching I found that a triangle number can be calculated by using the formula:
I am working on a project I would like to use a function in a class I created to return multiple values in order to populate a listbox. I wanted to use a do until loop to achieve this. I will just post a simplified example of what I am doing :
Public Function Listboxfiller Dim astring As String = "This is a string" Dim Counter as integer = 0 Do until Counter = 5 return astring Counter += 1 Loop
Then on the form I would do something like : lstListbox.Items.Add(Myclass.Listboxfiller)
What happens right now is that the listbox only gets the first value, when I ran through in debug mode I found the loop only runs once, even though it should go multiple times.
I am struggling here with introducing web services into a site I am currently working on. The background is as follows.
- I have a page switchboard.vb which will recieves incoming xml requests. - I parse these xml requests extracting its values, then setting them equal to the relevant global variables in switchboard.vb. - One of these variables will determine a 'requestType'. Based on this requestType I want the page to call particular web services that I will add. - These web services will then validate the user calling has permissions to access and execute it. - The switchboard.vb page will then generate an xml respose which will post to the client.
Here is a summary of the process getXML() parseXML() determineRequestType() executeRequest() rebuildXML() postXML()
The ways I can see to do this are: 1. Pass the variables into the required Function allowing it to pass back a pre formatted xml string. Pro: Simple Con: It is not really using the web service as it should be.
2. Pass the variables into the required Function as 'ByRef' values hense changing the original value on switchboard.vb Pro: allows me to format the outgoing xml on switchboard.vb and gives me more functionality with more individual variables as opposed to one string being passed back. Con: Is this taking advantage of a web service? When I tried this the web service form didnt give options to input test data. Possibly because I am using ByRef?
This is the function that I use in web service for getting current windows user.
<WebMethod()> _ Function User() As String Dim p() As String = Split(My.User.Name, "")
[code]....
When I run service on localhost it realy return current windows user name!The problem is when i run service from remote PC, in that case I got nothing from this function. What is problem with this service, and how I can get name of Windows user?

I have an asp.net project that's compiled on a server. On that same server I have a windows service that's running methods referenced from the asp.net .dll. Everything works fine except for when the httpcontext.current object needs to be accessed. I'm fairly certain that the cause of the .current being null is that it's referencing the shared library without an actual instance of the site running. In a previous version of the service I was able to find a workaround in asp.net by not using the context, however that is now a last resort as much of the architecture of the site has changed. Is there anyway to create an instance of the site and simulate a current httpcontext for the purposes of the service?
I developed a windows service project using vb.net and windows service is installed with logon account as admin's user name and password. Target of windows service is to read the pst file path location from windows registry for currently logged user by accessing the following registry key
The problem is , windows service can able to read the admin pst file path location if admin is logged in windows. When other user logged in windows, service is not able to read currently logged user's pst file path location from registry because of windows service is configured with admin user name and password. so it always reads admin's pst file location.
show me how to return multiple values from a function? I have my function in a seperate file within App_Code and here it is:Public Function GetQuoteStatus(ByVal QuoteID As String) As String

However this is all good and well for one returned value but what If I wanted to return multiple values.How do I access them?
In my code I enter a string in a text box and have the query check the server for the entry. If it exists it returns the string and the date into two separate variables. The database only has TrackingNumber and Date. Below is the code. As of right now i get "Invalid attempt to read when no data is present." at the "If (sdr("TrackingNumber") IsNot Nothing) Then" line.

I've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
