it is possible to create objects from strings.Supose I have a class Matrix with a Row(x) property and an array S = {"One","Two"}. Can i do something like this in vb.net?
For i = 0 To 1Dim S(i) = New MatrixNext i
Dim P As String() = One.Row(0)
'Which gives me the first row of Matrix One How can I create objects similar to this?
I'm new in this forum, and I'm a very very very basic user of the VB. How can I create a list of strings? I'm trying to make a chat with a robot. I put 2 labels. And my code is:

mylist = "hello", "bye"
If Not Label1.Text = mylist Then

Can you look at this code? It's a class module that I made so I can make our application more modular.
In the code there are 3 lines of code which have this as part of it: FormBrowseAttendance.ComboBoxLookupStudent.how I can change the coding to refer to this portion of code using these parameters:
pComboBoxName
pNameOfForm
I'm assuming these need to converted is some way but I don't know how to do it.

View 2 RepliesI need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?
View 2 RepliesIf I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
I'm trying to create a number of strings based on one long string that i'm passing.
Basically this is an example of my long string
StrMain = AL123456 - PR123456 - RD123456 - LO123456
So in this case I want to create 4 separate strings.
Str1 = AL123456
Str2 = PR123456
Str3 = RD123456
Str4 = LO123456
But there isn't always that many or there may be more so I need to count how many - there are and with that then create the amount strings needed.
I have a 2d array of chars and i need to start at (0,0) and creat a string and check it against some value then still then add another char to the first one and check it. I need to do that in every direction.[code]say im at the H their are like 8 way i need to check..

View 3 RepliesIf I have a list box or something that has a list of like 4 years (like 2006 through 2009), how do I programmatically make variables of these years with names like pTable2006, pTable2007, etc (as ITable of course). If this isn't possible and I have publicly declared these tables in the declarations (like pTable2006 as ITable, pTable2007 as ITable, etc), how can I programmatically assign these variables based on user choice?
What I'm asking is, if the user wants to choose years 2006 and 2007, how can I write this:
pTable & ListBox.Items.Item(0) = [table path string] & ListBox.Items.Item(0)
(please ignore the syntax of the "listbox", I'm just trying to come up with an example)
Whenever I put something like pTable & "string", I get an error.
I am trying to create a property for objects, though I am not sure if that is what it is called. For example, PictureBox.Image instead of Image I want to use my own property.
View 3 RepliesI use serializer classes for storing data and each class can hold an array of objects for the same class which is a key feature of the class. I declare this array as so:
myClassObjects(1000) as myClass
My question is- can I declare the array as an arraylist so I can sort and count objects in the array(list) quicker and easier and are there any drawbacks to taking this approach?
I want to make pictureboxes move from the top of the screen to the bottom of the screen (easy) when they reach the bottom I want them to cease to exist (do-able). But i want to create new ones that keep coming from the top. create an endless amount of pictureboxes while running the program?

I have to ask my first question at some point, so here she goes.I am trying to create a dynamic list of objects. The objects will have several types (String, Integer) associated with them. Currently I am forming a Collection as I instantiate new objects.Is there a prefered to map this collection to, say, a Datagridview? Will I have to Iterate through the collection and add the rows at each iteration?Would I be better served using an ArrayList or something else over a Collection?

threads that watch folders and process files. This works fine, but every time needs change to add a new folder or just change some existing rules I have to go in and change the program. I want to builda front end that storesprocessing infofor each watchfolder. The program would then read the configs and build the threads based on them. I cannot find a way to loop through creating the threads.

View 2 RepliesIs there a way to dynamically create an object using a string as the class name?I've been off VB for several years now, but to solve a problem in another language, I'm forced to develop a wrapper in this one. I have a factory method to dynamically create and return an object of a type based on input from elsewhere. The provided input is meant to be the class name from which to create an object from. Normal syntax means that the entire class has to be explicitly spelled out. To do it this way, there could literally be hundreds of if/then's or cases to handle all the available class/object choices within the referenced libs:
If c_name = "Button" then obj = new System.Windows.Forms.Button
If c_name = "Form" then obj = new System.Windows.Forms.Form

I am trying to maintain a total for multiple collection objects in a class. When I create a new object, it resets the total to zero, only adding the current value being passed to the function. I have tried to use a static variable, create a second variable to hold the old total while adding the new value. The base class holds the total value, while the sub class creates the new object that holds information. I am passing the new value to a function in the base class adding the new value to the total when each new record is created.
