I have the following statement and the function 'InitialiseOsTransform' is in a Module which is in the project.
If InitialiseOsTransform() = False Then But instead of the code going into this function it goes into the Paint function.
I have used the similar code in another project and it works correctly.

I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...

I've an app that starts to work from a module wich should load a form an do other things with a class library who raise an event an the form shoud cath it.The problem is that applicarion.run(frmMain) displays the form in the same thread the the code stops work while the form is open. And I need that the app works in this way because the user need to send files to the app using args and this avoid that the app init another instance of it (in other code) and update the form with the info when the event is raised.[code]

Yesterday I opened Visual Studio (2008 v 9.0.30729.1) and all the winform classes in my project display with class module icons with the little 'VB', instead of form module icons with the little form icon!
When I double click on a form module, the form designer doesn't open, just the code module.
When I run the project, it runs fine. There are no errors. The project builds fine.
I did Project --> show all files, and I can see the designer and resx files below the form module which doesn't look or act like a form module.
I can't open my forms to design them!

I am using Compact Framework 3.5 on a Symbol MC50.In my Sub Main it first checks to see if a database exists. If it does, it shows a login screen using the following code:
Dim login As frmLogin = New frmLogin()
If login.ShowDialog() = DialogResult.OK Then
Application.Run(New frmMain())
End If
This all works correctly and, when I close frmMain, it exits the application as expected.However, if the database check in Sub Main fails, I call the ShowDialog() method of another form that is used to create and fill the database from a live server. Here is the code for calling this form:
If Not File.Exists(SETTINGS_LOCALDB) Then
databaseExists = False
MessageBox.Show("Local DB does not exist. The database must be created before using the application.")[code].....
All of this code is being hit and frmMain does indeed load. However, when I click the close button in the top right nothing happens, no event occurs. Its as though the Windows events are not occurring.

I have a piece of JQuery AJAX that calls a VB.NET code-behind (class) that returns string data. It grabs some latest stats on a particular server. Now the code works, but the first time I press the refresh button data is returned and the alert "Refreshed" is shown on screen.
But if I press it again, the alert box "Refreshed" is shown twice, I click again three times! and on and on, until the time-out kicks in.It seems to be coming from the AJAX call and no where else. I'm at a loss at what could be calling this, I've tried deleting the data returned after success but no joy.
function RefreshServer(btn,div,id,ip) {
$('#aRefresh'+id).html("<img src=images/refreshServer.gif border=0 align=absmiddle />");
$("#"+btn).click(function() {
$.ajax({

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 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 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.

I have a VB .NET 2010 application. I added a C# project to my solution. I tried to call the form called 'main'. However, I could not figure out a way to do that. What is the best way to do that? I Goggled, and did not find anything. Actually I noticed that my Developer converted everything to VB .NET.

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?
