I'm trying to make a public array that I can use in Form1.vb and module1.vb.
It seems to work fine in Form1.vb but module1.vb complains about that it isn't declared.
This is how I've done it: I placed it right after this line in Form1.vb:
Public Class Form1
Public SuffixArray() As String
how I declare a Array that I can use in all forms and modules?
Public Property TabsCollection()() as String()()
Get
Return _tabsCollection
End Get
[code]....
but it errors saying: End of statement expected.
So, I make a public array: Public files As ArrayList
I try to add a value to the array inside of the "Form1_Load": files.add("Hello")
Which returns a null error. how to add values to a public array for multiple subs to access?
I'm trying to declare a array that I want to use in the module and in the forms. I like it to be usable all over but I cant get it to work.[code]...

View 10 Repliesi am new at everything VB.net/ASP.net. I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person. Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default. This is my code once they choose a user:

I am attempting to make a form public. I've start out with this class:[code]I can see the stupid form thru intellisense, but when this code is run I'm getting a null reference exception. I believe this is because the stupid form has not been initialized. I thought that placing 'new' in my class definition would initialize the form.
View 4 RepliesIs there any way to make a class instance public?In my mainform I define an instance of a certain class and then later on in some other forms which appear I want to alter this class.I try and pass them through when creating new instances of these other forms and it tells me Error3<instance of the class I want> cannot expose type <the class> outside the project through class <the form I want to edit it with>Which I gather from documentation is about it defeating the purpose to have a private class suddenly be thrown aroudn.but then how do I make it public? I can't define it in the first place as public myXClass as XClass, it only accepts private.

View 9 Repliesok basically i was trying to make a Control that exposes its protected properties to the public. example, you could call the protected DoubleBuffered property publicly. the problem is that this class called ExposedControl must be compatible with the type System.Windows.Forms.Control, meaning i should be able to create an ExposedControl using an existing Control so i had something like this in the constructor.
Public Sub New(ByVal control as Control) Me = control

I have a class inside a class.I need to expose the properties of the 2nd class to other classes, therefore it is public.However, I do not wish other classes to be able to create instances of this 2nd class, it should only be instantitated from its parent class.I thought I could resolve this issue by making the constructor of the 2nd class private, but this even prevents the parent class from instantiating its child class! How can I work around this, do I have to make the constructor public and allow anybody to create an instance of the class?

My app has three forms and one module; each form has it's own, private code, and the module has all of the shared, public functions and subprograms. One of my controls (MSFlexGrid) is "contained" by my form1 but must be referenced within the public module.
If I try to use a With statement in my module to reference form1's grid control, the control's name is flagged as an "undeclared variable name". Is there a way of either declaring or qualifying the control's name so that it can referenced outside its owning form?

I do have to create at runtime a list that will contains some methods. These will be called in proper time.
So far, I used reflection and have made an array of methodInfo.
The problem is that these methods do have different signature, and I also need somehow to get the value of the arguments to follow their method.
And finally, I need to be able to put all this together and invoke these method when the time comes

View 5 RepliesI've been making a table control for a few days, and I've got to the point of making it capable of accepting new data. To do this, I'm making it generate a row of text boxes, combo boxes, and date selection windows along the row that you're entering data into.
I've tried using an array of 'control' types and changing them to whatever specific control I need as I generate it. That sort of works. For example, the code under 'Case "Employees"' below will make a combo box display on the form, but 'ControlArray(i).Items.Add' gives an error because it doesn't think that ControlArray(i) is actually a combobox yet.
You might also be interested to know that everything will have to be dynamically generated since the table I'm using will not always be the same (and the Select Case code will eventually be replaced by something that checks for relationships in the database).
Dim ControlArray(NumberOfColumns - 1) As Control
For i As Integer = 0 To NumberOfColumns - 1
ControlArray(i) = New TextBox
