Sql Server - Returning Multiple Columns From SQL Procedure With .NET
Feb 21, 2010
I am using this vb.net code file to call a procedure to get dates (among other things). When I execute this procedure in SQL 2005 Server Management Studio, I get about 10 columns. However when I execute this code, the dataset seems to only have one index value, maybe I am misunderstanding something. When I change this
ds.Tables(0).Rows.Count.ToString
to
ds.Tables(1).Rows.Count.ToString <---changing the index value to 1
(or higher)
I get no information. So my question is;
Does the DataSet contain the other columns, only not indexed like an array? What I want to do is choose which of the columns to filter out and turn the rest into JSON formatted strings.

I'm doing a project in database development which requires to use a list box that will populate from a SQL Server database.I'm confused on setting up the listbox to have multiple columns that will be populated from a stored procedure within SQL.I drag and drop the listbox onto the form, size it, change it's property to multi-column, set column width to 10, but don't know what to do next.The listbox on the form design doesn't show multi-columns.

I am posting this here because the sql query seems to be fine, it is the VB code that is the issue. I am new to VB and I have a subroutine that imports a value for the strating and ending time of a report. The error I am getting is: Conversion failed when converting the varchar value 'Aug 20 2009 12:00PM' to data type int. Here is the code for both VB and SQL:

This problem has driven me mad for over a day now. I can create a connection to the database, I can execute sql and return results from that but I can't seem to call a stored Procedure. Here is the code
[Code]...
it works ok but no results are returned. I've verified that the procedure returns results for the user I'm logged in as. When the query was executing I could see a refcursor in there but it was empty. I must be going mad.

I am using LINQ queries inside a WCF service to return data to a Silverlight frontend. Problem is the columns being returned using LINQ are in alphabetical order and I want them the way they are ordered in the database instead. Does anyone know how to stop the alphabetical ordering of column names?

I am making an address book for my final project in school, and have a few questions. In my address book, there is a feature to add groups so you can sort your contacts. The problem is, the add group feature is in a different form, I tried calling a procedure from the parent form to refresh all data but it does not work.[code]

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?

I have a table with several rows of data that I need to return to the controller. In my view, I initially load the table by selection of a time period and clicking a button. The table loads all my relevant records but one of my table cells contains a dropdown list. So I should be able make a selection in the dropdown click "update" and my controller saves the changes.
So everything works until I try and save. The model that is sent to the controller is completely null. The list property I have tied to the table cells returns to the controller null.

like an Interop user control (VB.NET) to return and to accept multiple values from a get/set call.

i've done some basic parsing with text files before.
Scenario is i have 4 textboxes String (which contains the string i'm wanting to parse) sub1, sub2, and sub3. so the string is ex. 500000-1-2
- is the char that is the seperator
so the aim here is to get
500000 into sub1
1 into sub2
2 into sub3
the real string i'm wanting to parse is much more complex, but i'm keeping it simple here for a jumping off point so i can figure the rest out.

I have created a function which essentially enables me to output anything I need from my database in a similar method to Facebook's FQL querying method as a JSON text result. I can also use the same function to get the output as a Dictionary, or List of(Dictionary) to use with VB functions for other purposes.

I have a form which displays related data from three different tables. There is a foreign key between the master table and the two related. Currently I have three stored procedures to return the data based of the return key value from a search becuause I am using DataAdapters to select and modified the recordsets. This works great, but I'm sure adds a lot of overhead. In VB 2008 with SQL 2008, is there a way I could use only one stored procedure to accomplish this?

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.
<QueryPacket xmlns='urn:Microsoft.Search.Query.Document'>"
<Query>
<SupportedFormats>
<Format>urn:Microsoft.Search.Response</Format>
