VS 2010 : Return A Row From Datagridview As Array?
Feb 23, 2011
I have been having major problems with Datagridviews and attempting to retrieve one row at a time and then assigning that row to an array , Which can be used in another function.I have tried numerous ways to achieve this but none of them seem to work. something like 'Start array of no values to be filled during the while.
dim myArray as Array
While myDataGrid has Rows
assign myArray the values held within the cells of the first row
send myArray to another function for processing
END WHILE

I am creating a class that will represent a file and I am going to have lots of properties. Now I want the properties to return either a integer or a byte array. Is this possible or do I need to create 2 different properties one for the integer and one for the byte array? When I try I get. 'Public Property something As Integer' and 'Public Property something As Byte()' cannot overload each other because they differ only by return types.

I 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.

Before adding rows to a table I am evaluating the SSN number. These will later be flagged for correction so I am setting a datatable column to true or false if it passed muster or not.
I wrote a function to check the number and make the determination plus pad it with zeros and hyphens where they should be. My problem is I want to return the results in an array. I am getting system.string[] as the return value.[code]...

This is a school project, supposed to be a beggining VB.Net class. I'm having difficulty with one section, sorting the array is OK but I need to only return a 3 of it. I had it working when I was selecting single files but when I went to selecting multiple files at once the formula stopped working for me. I'm retuning the array just fine but the select a 3rd seems to just pass by without being acted upon. I've been working on this a long time and don't know where to look for an answer. Here is what I have for the sort method;
Private Sub sort()
Dim Count As Integer
Dim count2 As Integer

I'm trying to call a function from a sub, and have it return an array to the original sub.
I currently have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call Registry_GetUsers()
End Sub
[code]....
Which works, but I want to loop through each of the items in users from within the original sub, not the function, as it currently does.So I need to return the array to the original sub, so I can then iterate through it from there.

I'm using a binary search to return the index of a value in an array but on this occasion it return -2 when I'm expecting a positive 2 to be returned.
If cBudgetID.Contains(AdditionalCostBudgetID) Then
Pos1 = cBudgetID.BinarySearch(AdditionalCostBudgetID)
cCost.Item(Pos1) += AdditionalCost
ElseIf AdditionalCostBudgetID <> 0 Then
cBudgetID.Add(AdditionalCostBudgetID)
cCost.Add(AdditionalCost)
End If
Values:
AdditionalCostBudgetID = 53
ArrayList CBudgetId = 0) 50 1) 60 2) 53

I have a program which connects to an FTP server. my program needs to retreive the directory list of the server. I am doing this in the style of an OpenfileDialog control. now I can get all the information and fill the listview control. however the function I use to fill the listview control with the directory listing and file listing, returns a list(of string)
Because of this I can't determine if a file is a file and if a folder is a folder. I myself know which of them are because while getting the directorylists I check for a string value of D which means directory. if it doesn't have a D then it's a file.

Public Function Foo() as String() Dim bar As String = {"bar1","bar2","bar3"}
Return bar End Function
My situation is similar to the code sample above where I'm returning a string array from a function.
What I would like to do is just return the string array without having to declare a variable first and then return the variable.Something like this, although this obviously doesn't work:
Return {"bar1","bar2","bar3"}
Is it possible to do this, I can't seem to find a method that works?

I have a class called Customer. It has some property like custID,custName..etc. Inside Customer class I have a function which returns an array of customer.
I wrote a function like this :
Public Function InitLoadCustomerDetails() As Customer()
sql = "SELECT* FROM tblCust"
ds = classDC.queryHandler(sql, "InitCustomerDetails")
Dim customerArray(classDC.maxrow - 1) As Customer
Dim currentCustomer As New Customer
[Code] .....
But it is not returning an array. Just a customer variable??
Public Function InitLoadCustomerDetails() As Customer()
Return customerArray
End Function
Fix this to return an array of customer!!

I have the following in a .Net 2.0 app:
Private chequeColl() As Cheque
For i = 0 To m.Length - 2
chequeColl(i) = New Cheque()
[Code]....
I now want to make chequeColl only contain those items where Status is not equal to 41. In LINQ this would be easy but I can't think how to do it.
I cannot use the .Net 2.0 LINQ bridge products, I have to do this the old school way. At the end of it chequeColl must only contain those items that are not status of 41. I cannot have empty elements.

I need to provide a DLL that is consumed by a VBA app (Access 2003, late binding) and returns stuff that is retrieved from various WebServices. These WebServices publish methods that not only return a single object, but also arrays of them.
From the Access-app's point of view, it's no problem to consume i.e. an array of strings. However, there's also methods that return an array of a (proprietary) class. I can't seem to be able to consume such an array from VBA.[code]....
