I'm having trouble finding out how define this function so I can return the arrayRight now I am defining the returnobject as 'object' but I would like to do it properly.The Function goes something like this:
View 2 RepliesI need to return an array but the array size will change from one call of the function to another so I need away to storing the returned array. The function is as below, and as you can see the returned array will be of different sizes:

Im overiding getRolesForUser() I have 2 columns i return from the query IAdapter.GetRolesByUserName(userName) returns two columns (roleID, formID) How can I return them and access the two columns data? 2 dimensional array?

I'm trying to return changes to array data, including redimensioned arrays, from within a function call in code similar to:
fault = MyFunction(Array1, Array2)
Public Function MyFunction(ByVal inObj1 as UserStruture(), ByVal inObj2 and Integer(,)) as String
Dim myResult as String = "Failed"
Dim tmpStruct() as UserStructure = inObj1
[Code] .....
This works fine in updating the input array 'Array1', only when the redimensioning of tmpStruct is NOT performed. After redimensioning tmpStruct, the redimensioned array is passed back successfully into 'inObj1' within the function 'MyFunction', but is not passed out of the function call; i.e.
fault = MyFunction(Array1, Array2) -
The dimension of array 'Array1' out of the function call remains as it was before the function call. However, the data change; i.e.
tmpStruct(0).Nam = "New Name"
is passed successfully out of the function call.
Why the Redim operation is not passed back out of such function calls. I would like to return changes to arrays 'Array1' and 'Array2', plus a result string from the function call if I can. Furthermore, I would also like to change the dimension of the array within the function call, if required, and return the complete redimensioned array back out of the function call.
I should be able to pass an array of numbers, calculate average, lowest number, highest number, and standard deviation.the function returns an array containing the results. I dim public data
Public dataArray() As Double
Public DataIndex As Integer = 4
Private Function CalculateData(ByRef dtArray() As Double) As Double()
[code]....
I get an "error Number of indices is less than the number of dimensions of the indexed array" stats()If I add a dimension there like stats(Dataindex) I get an error "Value of type '1-dimensional array of Double' cannot be converted to 1-dimensional array of double".
My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".

Just come across the following snippet:
Public Function Checked() As Boolean
Return applyChange 'this is a string!

Whats going on here? How can a function with return type Boolean actually return a string? I'm assuming theres some implicit conversion going on here, which I'd rather not have.
I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:

If an object is created inside a function and the function returns that type of oject how is the memory handled.
Example:
Public Function GetEmployee(employeeid as integer) as employee
Dim oEmployee as new employee
oEmployee.FirstName="Bob"
[code]....
Does the variable that receive the object still a pointer to the memory location that was used inside the function?What about when you do a oEmployee2=oEmployee.Is oEmployee2 just a pointer? And any changes to oEmployee will now affect the other. Just trying to understand it from a memory perspective and how that scope works?

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 have two functions in a class. One function returns a datatable, the other one returns a dataset. Both functions are identical except of the return type (Datatable or dataset). I would like to have only one function which returns either dataset or datatable depending on what the user of the class wants. How can I do this.
Following code shows my function returning a datatable:
