MyApplication_Startup And Module Variable Declarations?
Dec 15, 2009
It is my understanding that all modules are initialized and that all their variables are set up prior to MyApplication_Startup. I have code that has worked well for quite some time (XP and Vista).The Myapplication_Startup code references variables and code located in a Module.However, with Windows 7 this does not work.Anny reference to a module (Data, SUB or FUNCTION) throws a Type Initialization error at runtime. How can I correct this behavior in Windows 7?

I have an issue with variables that are used to name For-Next loops. I have had this problem in a couple programs but not consistently, i.e. some variables work, some throw a warning (not an error).
The situation is this. I declare the variable along with all my declarations in a module-
Module MainModule
Public Counter1 As Integer
end Module 'MainModule
[Code]....
The type for variable 'Counter1' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Counter1', or use the fully qualified name (for example, 'Me.Counter1' or 'MyBase.Counter1'). In the past I've always broken down and changed the names to get rid of all those ugly warnings. Sometimes I have eliminated them from being declared in the module and declared them at call time. This is not how I program and I like to keep consistency throughout.
how I can get rid of this spotty, on-and-off nonsense? There is obviously a lot I don't understand about VS and I would have never taken it up but would have stopped 3 languages ago if I weren't forced into bulkier and bulkier languages (sorry about the rant. I feel OK now).

Although I have been programming for many years, successfully, in many different languages, translating my large Word VBA application into VB 2008 Express is driving me crazy. While I understand the theory of OOP and have even been on object-oriented courses, it seems I can't declare my objects correctly and use them in my code. As far as I know, I'm not trying to do more than the "language" is capable of doing, but here goes.
I want to start with "aList" which would be a Collections.Generic.Dictionary(Of String, String) object. Then I want a "bList" which is also a a Collections.Generic.Dictionary object. I would like each bList item to have a few individual simple properties (like a Byte and a String) then an aList instance as well. The application then gets a bList key value from the user, "copies" the corresponding bList item values into a work area, and does the necessary processing using the various bList(aList) / aList(bList) item values from the work area. I say "copies" because I assume that part is simply going to be a pointer copy rather than a long copy of lots of strings. Note that I really don't want to start using arrays here, as the application makes alot of use of Word VBA Dictionaries and I'd like to keep it that way if I can. Incidentally, so far, I have all my global data declarations in a separate Class, not on any of the application's forms.

I've read several articles and questions/answers that conclude the best practice is to let the JIT compiler do all the optimization for inline function calls. Makes sense. What about inline variable declarations? Does the compiler optimize these as well?
[Code]...
Of course I prefer the latter because it's easier to read and debug, but I can't afford the performance degradation if it exists. I have already identified this code as a bottleneck -- No need for retorts about premature optimization.

I'm having some problems with updating a form from a background thread, started in the MyApplication_Startup sub.As far as I know updating forms or controls on forms have to be done threadsafely.
When the application starts up, some threads are being created which create an object in which a download for a zipfile will be started. The object has some delegates to let the GUI know what the status of the download is, for example 'started' or 'finished'. Also the mainform will be shown on which a datagrid has been placed to show the user which files will be downloaded and in which phase the download is.
All this works amazingly fine but when I want to update the datagrid's cells p�r thread the datagrid aint updated. I know the problem is that the thread in which the Form is created isn't the same as the thread which wants to update the grid?

I declared the variables with in the first module to be loaded
Module Mod_Global Public DtFRM As String Public DTTo As String I can load the variable and read it with in the module. Ok, good so far. But sending the code to another module results in nothing in the variable.

I have an issue with an app i am writing, i need to make a variable accessible to any module or class within the project but that cant be accessed outside of the app as it is accessing info the end user shouldn't have access to.
Ok, well a practice i have gotten into in the last few years is to declare a module on the same page as the main form and declare variables either friend or public (global variables). with my app public is not good so i tried Protected Friend but i cant use this within a module.
I tried placing it at the top of the main form but one of my classes can't access it, what would be the right way to do as expected. besides the main form i have 2 classes call them class1 and class2:- main interacts with both classes class1 accesses class2 class2 doesn't access class1

I have a useform set up to have a user input value, and I would like to pass that value to a module. I have made the variable public along with the subroutine that I am trying to use the variable in. I have a message box display the value of the variable in the subroutine and the value is 0, even though I have inputted a value in the userform.
[YearForm]
Option Explicit
Public Sub UserForm_Click()
Me.intYear.Integer = Year

I have a public readonly variable in a module, but when I try to set it in my form load event for the first time I get 'ReadOnly' variable cannot be the target of an assignment. It is my understanding that a ReadOnly variable can only be set once and after that you would get an error when setting it.

Got a question regarding declaring a variable. Basically I have a module that writes to a text file using textwriter which is declared for the whole module to use at the top of the code. But what I want to do is clear the contents of the text file when the program is executed (using file.writealltext). The problem I have is that the file is obviously already in use as a result of the textwriter and the file cannot be modified because of this.
My question is: is there any way of declaring the textWriter object later on (not during the initial initialization of the module) without passing the object between functions? Setting the variable as inactive or something along those lines during initialization would be ideal.

I just need to know where my code is jacked -up at, I get an error when I created the module level variable ( class statement must end with a matching end class) problem is that every time I add an end class the next procedure is wrong with the same error, so what can I do to resolve this and why is this error coming up. Ultimate goal of this program is to add the invoice totals to the next element in the array each time the user clicks calculate, which displays in a message when the user clicks the exit button, also this code will sort the invoice totals in the array.
Public Class frmInvoiceTotal
Dim SumInvoice(4) As Decimal 'Delareation of two module- level variables
Dim I As Integer = 0' the index I can use to work with this array
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

I used to do this is VB6:
Type Record
A As Long
B As String

Dim Rec As Record
When I keyed in "Type" in my declarations, I was asked to change it to "Structure". After that, I was not able to define anything inside. So, what do I need to do?

This correctly returns the memory value as string. So yeah, now it's just the Single that's causing issues.

I have a project that is structured as follows:
[Code]...
I want the module to execute first before anything else, and so I call module.main() from the MyApplication startup event. At about the point that program execution gets to the beginning of module-level declarations in the module, it also starts running though the class-level declarations in the thread classes, but long before the threads are declared or the threads are started in the module code. I can't figure out why it happens! Is there some way of supressing that until later (i.e when those classes are actually instantiated)?

In my code the application will restart using the Application.Restart statement from another form named frmDatabase.
The application seems to restart while debugging but yet the dataset, tables etc which is declared right below the class declaration for the startup form seems to fail initializing when the restart is done.
Compiling and running the application works like a charm and there is no error like this when running the executeable.
I also Inserted a breakpoint in the Form_Load event and the debugger seems to skip all the statements when the application is restarted all the way down to where the exception occurs.

Public Class frmMain
Public objConnection As New OleDbConnection(strConnectionString)
