Mar 30, 2011Is it possible to make a function that returns both a datatable AND a list(of custom class) at the same?In my GUI layer, the main form (the application is MDI) calls this function and it has to fill the datagrid on one of its child forms and it also has to fill lot of other child forms with various information that is calculated from my custom class properties.Both the datatable and the class properties are created from the same external database and that's why I don't want to have two separate functions.

Mar 15, 2011I have created a function that takes a Car Registation as its argument and I want it to return 3 values (Make, Model, Price and of course True).The code itself works fine (it returning each Individual value but can't find a way to get ALL of them from 1 function) However I need to actually return all 3 values, and I cannot see how to do this with a simple function.

VS 2010 Creating A Function But Have To Return A Value?
May 5, 2010Alright so basically I have created a function so it can get the data and do the following things, etc
Public Function stats(ByVal texti As String, ByVal imageURL As String) As String
Label1.Text = weapontexti
MyImage.Image = imageURL
End Function
I basically want to do something like that ^ and then be able to enter things (instead of writing lots and lots of code):This is what I want the function to do when I click a button:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
weaponstats("Example Text", "images/etcimage.png")End Sub
Is there anyway (even if it requires something else rather than functions) to this without an error?

VS 2010 : Establish An OLEDB Connection And Return The Values From The Selected Table To A DataGridView?
Apr 16, 2010I am unable to load the dat into the data Grid. Here is where I keep getting stuck.
dgvOleDb1 = table.Select
dgvOleDb1.DataSource = DataGridViewEditMode.EditProgrammatically
dgvOleDb1.DataSource = ds.Tables(0)
I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

Return An (Anonymous Type With A Function) From A Function?
Mar 3, 2011Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:
[code]...
I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:
copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)

How To Use A Function's Return Value
Mar 8, 2009So the program I am writing validates the controls on the page on button_click.
I want to write a function which checks which step the program is at (0-7) then return something depending on whether or not it validated.
My plan was to return the control which was not valid.
Private Function ValidateInputs() As Control
Select Case wizardStep
Case 0
[Code].....
1. could I return the names off all the controls which did not validate?
2. should I be returning a control type or would something like a string be better?

Return NaN From A Function?
Oct 5, 2010I've created my own version of HexToDec() to properly handle the negative flag. I saw other versions online that used "Not(value)" to do the Pos/Neg inversion, but that does not generate the proper value... No, it's not the most elegant my any means. But I couldn't find anything online that actually worked.
Long story short, I want to return NaN in the case that the function is passed a string that is not a valid hex string...
How do I do that? Everything I've tried generates a compiler error... (assign return value to double.nan, assign return value to non-numeric, etc)
Existing function is below:
Function HexToDec(ByVal hexStr As String, Optional ByVal signed As Boolean = False) As Long

CLR - Function/Operator Without Return Value?
Sep 4, 2009I've create a new project, and set treat all warnings as errors in the compile tab.All the other warnings seem to be treated as errors, except the one which I'm interested in "Function/Operator without return value".I have a simple function within a class, which does not show an error if I do not add a return statement to that function. I have read in many places that VB.Net returns a "hidden" default value if the returns statement is forgotten.My software went out to production where an overloaded function was missing a return statement, which wasn't highlighted due to the above.

Function Without Return Type?
Dec 23, 2010In my project (which I inherited from someone) there are a lot of functions like:

And they are called like this:
DoSomething(s)
So the return value is ignored (which is object, as I see in the docs). Is it safe to change all these functions to Subs? Could I break something which isn't so obvious?
