Public Structure In Web Service As Return Value In Function
Sep 24, 2010I have a windows app that references a web service I created. In the web service, I created a function that needed to return more than one value. Because of this, I created a public structure in the web service:
Public Structure MyRecordSet
Public lstOfDataInRecord As List(Of String)
Public iNumberOfRecords As Integer
End Structure
Here's the function - the return value is MyNewRecordSet:
Dim MyNewRecordSet As MyRecordSet <WebMethod()> _
Public Function GetDataReturnList(ByVal sql As String, ByVal sTableName As String) As MyRecordSet
MyNewRecordSet.lstOfDataInRecord = New List(Of String)
[Code] .....
Anyway, I see it's a conversion issue, but not sure how to resolve it. This is my first attempt to use a public structure in a web service and receive a return on it from my app.

View 1 RepliesCode An Array Of Structure?
Mar 26, 2009I am once again struggling with my weekly project. I am assigned to write a program that converts a predetermined english sentence to both french and german. The code is to contain an Array and a structure. Also we have not covered retrieving array data from a TXT file, so we are to hard code in the array data. I coded the structure and the array, I added the array data, but am confused how to access the data. The examples I have found all deal with retrieving data from a TXT file. Can someone give me a nudge in the right direction.[code]....

Speeding Up Code That Copies Database Structure To XML
Aug 23, 2010I have a database structure filled with data that I'm trying to write out to an XML file. Here's a taste of the way the VB code is structured:[code]I can't see or report any progress, because the processing is all tied to one giant LINQ query. Even if I can't make it any faster, I'd like to know how much longer I have to wait. My first version of this code had For loops instead of queries, so I could display progress, but it took a loot longer.Obviously I'd like to speed this up considerably. It seems like there should be a simpler way to convert the data to an XML file, especially since the database structure was created from the XSD in the first place.

2. How can I copy just the structure of the tables and not the data?

Fill Fields In A Structure In A Single Line Of Code?
Sep 21, 2009Just suppose that I define a structure, and an array such as
Structure Person
Dim First_Name as String
Dim Last_Name as String
[code]....
Can I fill in my list of people using a single line of code for each record? Something like this, it doesn't work, but this shows the sort of thing I mean.
My_List(0) = {'John', 'Smith', 24, '555-1234'}
My_List(1) = {'George', 'Jones', 31, '555-8123'}
My_List(2) = {'Tom', 'Green', 40, '555-3434'}
It's easy enough to fill it in line by line. I could do that without problem. But I want to be able to look at the code and see the contents of each line. Doing it as above would make it easier to read.I could make it a multidimensional array of strings, rather than a structure.If it makes any difference I'm using Visual Basic 2005 Express Edition.
