Returning One Or More Values From A Function?
Apr 20, 2010Is 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.

Jul 31, 2009I'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.
.net - Inherited Classes Returning Different Values?
Jun 25, 2010This 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?
Class Not Returning Accurate Values?

Returning Multiple Values From Function
Mar 17, 2009I 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.
WCF Service Not Returning Current Values?
Sep 27, 2009I 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
View 13 RepliesWeb Services And Returning Multiple Values
Jan 14, 2009I 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?

VS 2010 - Reading Text File And Returning Values To Textbox
Apr 17, 2011I'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.
Private Sub saveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click

.Net Code Returning Different Result Than C# Code?
Apr 20, 2012The following code in C# gives result "228452386"
UInt32 a;
int k = 0;
a = 0x9E3779B9;
a += (UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24));
After above code is ran, "a" contains "228452386" But the following same code in VB.Net results in "Arithmetic operation resulted in an overflow". Basically the last statement is returning value "1868983913" so the runtime error is generated.
Dim a As UInt32
Dim k As Integer = 0
a = &H9E3779B9UI
a += CUInt(AscW(url(k + 0)) + (AscW(url(k + 1)) << 8) + (AscW(url(k + 2)) << 16) + (AscW(url(k + 3)) << 24))
note the variable "url" in above code could be any string and it is same for both codes.
EDIT:When I run the following statements in both C# and VB.Net than they both return same value
C#
(UInt32)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24))
VB.Net
CUInt(AscW(url(k + 0)) + (AscW(url(k + 1)) << 8) + (AscW(url(k + 2)) << 16) + (AscW(url(k + 3)) << 24))
Both statements return value "1868983913" for "url" "info:microsoft.com". But when I run complete statement with a += ..then VB.Net gives error while C# returns value "228452386".
