I need to declare dozens of objects (Textboxes and Checkboxes mostly) into differents arrays but when i try to do this, they are added as strings and not as objects. I'd like to add them as objects to run through them recursively.

I've written a class to wrap my network interface. The problem I'm having is with declaring the objects I need.
In the two networking examples I have, they declare their objects as such[code]...
I am using vb .net & crystal report 11 , I m using 4 parameters in crystal report 1 st is "tcomp" , 2 nd is "tled_name", 3rd is "tdt_form", 4th is "tdt_to", the problem is, when I use first 2 parameters it is working well but when I add other last 2 parameter it's shown error message:
' Declare the parameter related objects. '
Dim crParameterDiscreteValue As ParameterDiscreteValue
Dim crParameterFieldDefinitions As ParameterFieldDefinitions
Dim crParameterFieldLocation As ParameterFieldDefinition
Dim crParameterValues As ParameterValues

I've come up with the following and it's partly working.
Public serial1, serial2, serial3, serial4, serial5 As SerialPort
Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)

I have a nested class, let's call it class1 and it has class2 inside it; VB.Net eg:[code]
1) How can I define X number of Class2 objects[let's call it: Node(x) array]** with NEW() subroutine called?' this raises error: dim cls2(n) as new class2 end sub.
2) How can I return actual number of Node() array? [code]Outside my class in main project I define cls1 object:[code]Now an array of class2 is created inside cls1.
3) Now,How can I access All of them[node(x) array which is created inside cls1] with all properties and methods available?
I remember I wrote a ProcessManager class with this functionality in .net 2003, nearly 4 years age, I don't have the code now.
I have a little syntax declare problem in VB.Net.
Dim proxy As USImportoerServiceTypeClient = DMRUtils.CreateAndConfigureClient()
Dim request As New USDeclare_I()
request.DeclareCollection = New US_ITypeDeclare() {}
[code]....
This above code do not work, becase the "US_ITypeDeclare() {}" is empty an only contains a new DeclareCollectionStructure
declare a KoeretoejErklaeringStructure to this an set this date value til "DeclareCollectionStructure.DeclareCollectionValidDate" ?

View 1 RepliesCan anyone tell me how I would declare an array for data that will come from textboxes? Every example I find seems to be data that comes from an input box, and the array name would just be strInputbox, for example. However, in my case the user will input data into several textboxes (each named txtBox1, txtBox2, txtBox3, etc.) and I'm not sure how to write this.
Thank you.

How do you declare an array when the array is initially empty?? I am taking multiple measurements from a meter that I want to put into an array. How would I declare that?? Here is my code to accept the last measured value.
HTML
Dim measResult as string
For I as Integer = 1 to 4
measResult = objDevice.gpibRead(i, 30) ''30 is the buffer size
Next
How can I set up measResult so it is an array that will hold all of the measurements from the meter?? I have tried Dim measResult() as string, Dim measResult() as String = objDevice.gpibRead(1, 30) but no luck.

View 3 Repliesi know how to declare a simple array and intialises its values, but i dont know how to get its results out of it. let me explain what i want.i've basically made like a Quiz, so the array(s) needs to hold 20 questions and 20 anwers. and i ve put these separately in each array, i.e. i have 2 arrays one with questions and the other with answers.when the user of my program presses ' get a Quiz Question', they retrive a question. Then the user types in an answer and using the submit button sends the answer for it to be verifed. how do u make sure that the question has a coressponding answer to it. as ive sed i have 2 separate arrays, i dont know how tell vb that when a particular question appears that it has a corresponding answer. If it matches a positive message appears, i.e.good otherwise wrong will appear.Also i need to randomize the way the questions appear in the quiz so they dont follow the same order when they are seen for the second time?
View 5 RepliesI am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?
So I have an assignment dealing with arrays for school but first I will start it off with the simple question as to where I am stuck now. I was wondering what the simplest way is to declare all the numbers in an array without going down the list one by one ( ArrayA(1) = 1, ArrayA(2) = 3 and so on.) I was wondering if the simplest way to do this is just by putting: ArrayA = ArrayA += 1 or what the simplest way to do this is.
