I have a .aspx webform, with code behind to handle data entered by user, most fields are in double.At business layer, at other class, let say there is a function: [code]I just wondering whether this is the correct way of writing it? And if I have more than 20 fields of double value, then I should declare additional 20 double value?

I have function in my asp.net/vb application with following signature:Public Function ExtractText(node As XmlNode) As String..I want to call it/pass xmlnode. How to create an Xml node with value:<mynode Id="7743" Type="context" StartNode="4356" EndNode="1234"></mynode>
pass an array to a function, like the code below shows
Private Sub SomeFunction(ByVal PassedArray() As String) For i As Integer = 0 To PassedArray.Count - 1 Debug.WriteLine(PassedArray(i))
[code]....
But is there a way to pass a constant array to a function in VB .Net, for instance in PHP you could write
function SomeFunction($array) { for($i=0;$i<count($array);$i++) {
[code]....
So to reiterate: Is there any way to pass a constant array directly to a function in VB .Net? Is there any benefit in doing so? I imagine a few bytes of memory could be spared.
PS.SomeFunction({"some", "array", "member"}) ' this obviously gives a syntax error
It looks like passing a list's enumerator to a function "byval" is quite different than passing it "byref". Essentially, regular "byval" passing will NOT change the caller's "enumerator.Current value", even if the function advances the enumerator. I was wondering if anyone knows why this is the case? Is an enumerator a primitive like an integer, without an object reference, and hence changes to it don't get reflected in the caller?This function is byval, and gets stuck in an infinite loop, spitting out "1" message boxes, because the enumerator's "current" never advances past 5.[code]The difference between the two functions is only whether the listFirstItem__ function accepts a byval or a byref enumerator.
I am trying to use a simple quicksort routine for a multidimensional array but cannot figure out the syntax. I am stumped because it works fine in VB6 but no luck in .Net

Trying to generate a Datagridview based on a query which is working fine.
Basic method is:
Create DbAdapter (MySQL) Create DataSet Fill Dataset with DbAdapter.Fill Set Datasource of DG to Dataset Works fine, have used a commandbuilder to handle updating, inserting and deleting. Where this doesn't work is if I pass a MySQL function in my query, e.g.
SELECT FROM testtable TestID, SomeFunctionForward(someproperty), anothersfield
A quick check shows the field omitted from Update and Insert. How do I go about 'setting this property' so it will work on the query with the CommandBuilder. It needs to be done in inverse, i.e.
INSERT INTO testtable TestID, someproperty, anothersfield VALUES SomeFunctionBackward("somepropertyvalue"), "anothersfieldvalue"
i have a very simple problem but i can't figure how to fix it.I'll explain, i have 3 array named "Auto, Legumes, Films". I i making a function so whenever the selecteditem of the combobox change(Auto, Legumes or Films) the name of the selecteditem is passed to a function. The function use this name to display the items of the corresponding table in a listbox.The 3 different item name in the combobox match the name of the 3 tables, so i want to be able to re-use the name dynamically in my function.
Code where i call the function: Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbchoix.SelectedIndexChanged
This maybe academic but I'd like to be able to pass the MethodBase.GetCurrentMethod() to another function. That way I could split apart the different parameters in one place. What I'm currently doing is something like this...

However, I need to reference Url and ProductID in the function and I don't know how to pass them as parameters or get their values from the original function.

I'm making the transition from VB6 (at which I was quite proficient) to VS2008, and I'm running in to a few 'snafoos' as I go. The most recent one (which I haven't yet been able to work out) is I'm trying to figure out how to pass a control (specifically a 'picture box' if that matters) to a function in a seperate class. This was pretty straight forward in VB6, but for the life of me, I can't seem to figure out how to declare the subroutine.
I'm a beginner when it comes to Visual Basic coding and I need some help with an error I'm getting. I'm trying to pass a structure array to a function to figure out a student's grade. I'm getting the error that 'QuizOne' is not a member of System.Array. Here is my code:
The case is that I have two comboboxes (country and state) and a simple code to populate the state combobox accordingly depending on the selected country. Ok this is simple and easy, and this code is within the country combo change event.The case is that I have more than one pairs of those comboboxes and I wouldnt like to repeat all the populate code into every country combo change event.Actually I would like to have only one function and just call it passing as parameter a reference to the combobox I want to populate. Then I could use that reference into the function.
I am trying to pass a control's id to a javascript function that adds the value of it (the control which is a textbox) to a listbox but apparently I am not getting it right.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed.Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function:
Module Module1 Public Function LookUpNow(ByVal userInput As String) As String LookUpNow = userInput Return userInput
VB.NET is not letting me dance with both feet, or piss with both hands. I've got one foot and one arm tied behind my back at every turn. I want to use this statement in a function: Return CType(Formatter.Deserialize(FS), DS) Seems doable, right?
Function ReadFileStream(ByRef FS As FileStream, ByRef DS As Object) Dim Formatter As New BinaryFormatter FS.Position = 0 Return CType(Formatter.Deserialize(FS), DS) End Function
Right? I mean, CType only accepts a class name as the second argument. I can't give it an instance of a class, or it croaks. Yet if I try to pass the class name as the argument to that function: DataInfo = ReadFileStream(FileStream1, DataStruct)
VB.NET croaks on this, too, complaining that "'DataStruct' is a type and cannot be used as an expression.". It's used as an expression by CType just fine outside of the function. Does the VB.NET legislature provide a clause that allows for a 'Type' to be passed as an argument in a function? Writing all the supporting code ten million times to deserialize a file using CType ten million times in a large application will get very complicated and tricky very quickly. It should be handled by a routine so that any cases and adjustments that come up can be dealt with in one spot.
I have a function that requires a form passed to it. Currently im using:ByVal oThisFormA As FormIf I do this though, obviously where I require txtboxes etc from the form being passed in arent recognised. e.g txtSurname is a textbox on a form called frmCustomer I have, but unless I use byVal oThisFormA as frmCustomerI will just get an error txtSurname is not a member of System.Windows.Forms.Form
