Call Module Functions Directly In .NET?
Apr 29, 2010
I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?

I have this weird issue:I developed an application with a sequence like this login form -> mainform (=mdi parent) --> some functionform (mdi-child)--> report form
The reportform contains a reportviewer and will display different dataset queries depending on the state of some radio buttons which are located on the previous form ('some function form'). When I run the project directly from the 'some function form' (set startup form for project) things work great. The report shows the correct data depending on choices made on the previous form.But....when I run the project all the way from login and mainform it doesn't work. Seems like the choices made on the "some function form' are not coming through to the report form.

if anyone knows if I can get a listing of all of the sub/functions in a class/module. Just the definitions (That is, the name, paramaters etc., but not the code).

So I am having an issue where I want to call a variable without addressing it directly and I get an error for it:
Conversion from string "player1BuzzLock" to type 'Boolean' is not valid.
This is technically correct but why would it fail?
Dim player1BuzzLock As Boolean = False
Dim PlayerNum as Integer = 1
'...
Dim playerBuzzLock As Boolean = CType("player" & PlayerNum.ToString & "BuzzLock", Boolean)

Even though there are many examples of Invoke operations, I can't find something that works for me. (I'm using VS 2008, and working in VB)Here is what i have:
A main module with functions (thread 1) that starts a BeginRead for a TCPClient. When the callback function executes (on thread 3), I want to call a function from the main module, in the main thread. All I get even with Invokes is calling functions that always run in thread 3, not the parent thread.
I call:MsgBox("Function name: " & Thread.CurrentThread.ManagedThreadId)
in each of my functions do determine on what thread it is executed. At some point, from the infinite read callback function I will have to get a function to show a form, but that function gets caught in the callback thread and freezes, instead of running in the main thread.PS: the callback that I pass to the BeginRead of the TCPClient is a function, not a class, so I can't use raise events.All I need is to call a function to run in the main thread (main module) from another thread.

i've created a Sub in a Form.
I've created another Sub in a module.
I call the Sub in the module from the form, passing the form into the Sub defined in the module.
Then i add an Handler to an istance of a control (for example mousemove) and i want to give to this handler the execution of the Sub defined in the form.
Example.
Class form1
Sub Form1Sub()
ModuleSub(me)
[Code]....
The problem is that i don't know hot to call the Sub defined in the form, in the Sub handler using the istance of the form passed in the Sub paramenter in the module...

I have a main form (frmPos) and through a module (modTransaction) I open and close several other forms. This works flawlessly. However, when the function on the module is finalized, I want to clear the main (open) form. Therefore, I made a public sub (clearForm) on the main form and when I call this from the main form it works.

say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?

Visual Studio 2008, Standard Edition VB.NET I have only limited experience using the background worker, and all that I've done with it thus far was fairly straightforward and worked fine.
I am now looking to run a process in a background worker which calls various functions and/or subroutines, but of course it generates an error indicating that it's on the main thread (or something like that - I don't recall exactly, but that was the crux of it).

The company I work for has a VB6 project that is using an ACCESS database.The project consists of seperate modules such as Accounts Payable, Payroll, General Ledger, and Inventory.At the current time each module is a seperate project in VB6 and the EXE files are called when needed.In total there are about 1300 forms in the project.We are moving from ACCESS to Sql Server and from VB6 to VB2008.The question that I (we) have is as follows; Should we continue to keep each module seperate and call the EXE's or should we create one large project?What are the pros and cons for each way?Is there something written that explains the advantages of either?

I have a form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()
End Sub
Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?
