Public Sub Label Changes On A Form Don't Work When Called From A Module?
Dec 15, 2009
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'm working on a project for my VB class at school. I am creating a form with several inputs and it calculates the total amount owed for a car sale. I have a text box for input of the TRADE IN VALUE of a car. the program is looking for a numeric input. If there is no trade in, how can i get this box to default to 0.00 so it doesnt error the program?

I'm trying to write a sub that when sent a form (if its needed) will create a label on that form. This is because all of the forms will have the same title label. My problem is that, basically, I have no idea how to do this. I also can't get labels to create when the code is written into the form itself; I tried:

I have a Main Module that loads a form. I want to update text on a Label, my code is:
Public mFormSplash As Form = New FormSplash
Sub Main
With mFormSplash[code]....
The code loads the form OK but does not update the Label's text (LabelStatus)I am getting an error Error:
'LabelStatus' is not a member of 'System.Windows.Forms.Form'.
This worked ok on a previous project and I can't work out what is different.

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'm converting a VB.net library to C# and having trouble finding the C# equivalent to a VB.Net Public Module.
In the same VB class is a With block. Any idea what the equivalent might be for that as well.

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]

I have a situation where I have several VB.NET Modules in the same Logical-Module of a large application. I would like the update function of each module to be public, but I would like users to be forced to qualify the function call with the module name.
ModuleName.Update()
instead of
Update()
Is this possible?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]

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.

Can one client call a public property within a VB.NET module and see the value of that public property changed by another client accessing it at the same time?
[Code].....
I'm running into random instances where it looks like another client might be modifying (by setting) the value of GetSetDateTime DURING the first client's run through of WhateverMethod(). This is alarming to me and I've been trying to figure out if that's a possibility.

I have a form named FrmDrvouchers. It contains some public subprocedures.I call these subs from another form which opens from a form which is opened from FrmDrVouchers as a dialog.When I open FrmDrvouchers directly, everything works. But when I call FrmDrvouchers from another project which is also part of this solution, its public subs don't work when I call them from another (dialog) form.
Here is the code of the Button Click from which I open FrmDrvouchers:
Dim FrmDrv As FrmDrVouchers = New FrmDrVouchers()
FrmDrv.Show()
This works, but those public subs don't. Why?It just skip what i want to do, but not throws any Exceptions,Now I m posting my Code,,, plz have a look on that,,Here is my Main form's MenuStrip Button Click code :
Private Sub CashPaymentToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CashPaymentToolStripMenuItem.Click
Dim DrVouchers As Transactions.FrmDebitVouchers = Transactions.New FrmDebitVouchers()
