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

I have multiple forms and have multiple declarations that I need for all the forms, is there a better way than declaring them each time on each form? Can a .dll do this, if so does it require the .dll to be a seperate file than the final .exe file. Or is there someway to reference the variables on other forms?

(me = an absolute beginner in WPF / VB2010) how to get the type of sender in (ByVal sender As Object)? Purpose: when two different Objects call the same subroutine, find out which one actually called it.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click
sayHello(sender)
End Sub

Just as a secondary question, usually I reduce: -(ByVal sender As System.Object, ByVal e As System.EventArgs) to just () for most occurrences of auto-generated subroutines. Is there any harm in doing this? I cant see any reduction in performance but do get more readability.

I'm trying to learn more about assembly security (something I have basically neglected until recently because security in general is such a huge topic), and I have a question about CAS assembly level declarations.I get how to use them (basically) and the more blunt points of the subect, but I'm still not clear on where assembly level declarations should be made. Basically, where in the solution do you put:

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?

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 have a project that is structured as follows:

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)?
On my main application i have a button which shows an "advanced options" form, if the "debug" is checked i was trying to enable/disable visability of a couple of text boxes on the applications main screen but when i tried:

View 5 RepliesI 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).

View 4 RepliesI'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.
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.
Declarations:
Public Class frmMain
Public objConnection As New OleDbConnection(strConnectionString)
Public objDataSet As New DataSet
Public objCommand As New OleDbCommand
Public objDataAdapter As New OleDbDataAdapter(objCommand)

I'm BASICally wanting to know what I should look into for saving multiple variables of a custom class object to be loaded later. I've seen some things about text, and I can do that fine, but don't think it would be the proper/best way of handling things
at all. I also saw some talk of XML, SQL tables, etc. I just need a point in the right direction.
For a bit more info on my actual project, I was tinkering with a 'simple' program to allow users to create rooms/objects/etc., which will then be converted into Inform 7 language (an interactive-fiction language).The variables needing stored are objects with a number of string variables and integer variables. I need to be able to save those, then load them out later into an array of said objects.
For anyone needing a more VISUAL image of what I mean, here are a few screenshots to show you what I mean. Also, if anyone has ever used Adrift, it is (at the moment) very similar to it, but for the Inform language.

I have a DataGridView. I'd like the user to be able to select multiple cells using ctrl/shift. Then, as they type, I want the contents to update in all the selected cells. I'd prefer it if this happened as they type but I'd live with it updating the other selected cells when they leave the current cell.
I've tried hooking in to various events to to this but in each case there seems to be one problem or another that stops me doing it.
