VS 2008 Rising Events From Class Library Called From Module

Jan 26, 2010

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.

Convert A Module To Class Library?

May 21, 2011

I have a single solution with 2 projects. One project contains all my forms and some other modules and the other project has 1 module with 1 giant class in it. I try to click on properties and change the output type, but it won't let me make it a Class Library, the only 2 options are "Windows Application" or "Console Application". The startup object is the module, and the project has references to a socket component.

Class Library Events?

Mar 6, 2012

I`ve made a .NET component in C#. After that, i`ve created a class library in VB.NET and added this C# component and a couple of buttons to the library (creating another component now with buttons). So far, so good.The problem is: when i use this final component (vb.net class library), i want to link all MouseClick Events of its own components (buttons and C# component). In other words, when i add this final class library to my VB solution, it has its own MouseClick event. But when i click inside it doesnt raise the click event unless i do not click in the buttons or in the C# component inside it. I want to raise this event in the application wherever i click (inside or outside its own components).

Raising Events In A Class Library Exposed To COM?

Dec 20, 2010

I'm trying to write a wrapper to a service, which will be used by an existing VB6 project. I've got most of the basic framework working, except for one important aspect: I can reference the wrapper in a VB6 project and subs/function calls etc. work as expected, but events do not. The events are visible in the VB6 app, but they never fire.

VB.NET Code:

Public Event Action_Response(ByVal Status as String)
Public Function TestEvent()
RaiseEvent Action_Response("Test Done")

[Code]....

So, the cmdTest button code prints 'Done' as expected, but the Action_Response event doesn't fire. Is there something else do I need to do to get the event to fire?

VS 2008 Moving Click Events To Module?

Feb 14, 2010

My program's code is getting a bit jumbled with all the subroutines for button clicks, etc. I want to move them into a more manageable set of modules, but I get the following compile error:

Quote:

Handles clause requires a WithEvents variable defined in the containing type or one of its base types.

For each event. Clearly I have to define a WithEvents variable, but I have no idea how or where to.

VS 2008 Custom Class Called CustomItem That Holds Name And 'SomeProperty' Properties

Apr 22, 2009

Let's say I have a custom class called CustomItem that holds the Name and 'SomeProperty' properties:[code]Now, on the click of a Button, I want to select the CustomItem whose SomeProperty is equal to "Property 4". Of course, this is just "Item 4", but the names and properties are not that correlated in the real application than they are in this example.I have spent ages a long time ago figuring out how to do this. I could not directly set the SelectedItem, because I first need to get the CustomItem that actually matches my condition (SomeProperty = "Property 4"). My solution was to use a loop, looping through each item in the ListBox, and setting the SelectedItem when the right property has been found.[code]Now, is this the correct way to approach this problem? Is the LINQ query correct, or can it be done easier, without the casting? Also, is the LINQ query faster than the For loop, especially for a large amount of items? I expect it to be, but I don't know how to test this.

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...

VS 2008 - Class Module Gets Data Entry From Form

Dec 16, 2010

I've been coding a Windows applicaton for the past seven months but there aren't a lot of "windows" in the application so I have a question on getting and returning data from forms. I display a form and the user makes a listbox selection then presses Ok. Normally I can proceed from there (in a class module) with values from the config file, but sometimes his selection will require me to ask for more information. So I want the class to display a form, pass control to it, then when the user hits OK on this form, return to the class. What is happening is the class continues with all its inline code and function calls and doesn't show the form until the end of its current function.

Dim flClientInputFile As New CFile
Dim flPreparedOutputFile As New CFile
Dim lRecordCount As Long
Dim sProcessing As String
Dim sTest As String
Dim frmAbc As New frmAbc
frmAbc.Show()
frmAbc.Activate()
x()

When I run and step through this code, I find I'm in x() before I even saw the form. x() needs the data the user has entered on frmAbc in order to continue.

VS 2008 - Sub Main In Module Versus Shared Class

Feb 17, 2010

In VB6 I always wrote my apps using Sub Main as the starting point. I see in .NET I'm able to wrap it in a shared class (see [URL] for example). However, the downside is that I can't declare any class-level variables, because of course the class is never instantiated. Being shared, it limits what the code can do. So, any benefit to use a shared class and shared sub main which I'm missing here.

Otherwise it seems using a module (as in VB6) provides a lot more flexibility. Of course, I should also ask if "Application Framework" is really the way to go for real-world apps, or if it's only there for beginners and real-world coders turn it off and use Sub Main instead? If so, how are the events "UnhandledException" and "NetworkAvailabilityChanged" done if App Framework is turned off?

VS 2008 Custom Dialog In A Class Library?

Mar 3, 2010

It's been a while since I last posted something, but this attracted my attention. Since many of my programs share the same type of code, I decided to dump it all in a class library for other programs to use.

Now I have a problem, Windows Forms in a class library can't be displayed. There is no "Show(Dialog)" command, only some for event handling. All properties are gone as well. The only way I managed to display a form is by making it as a new variable: 'Dim f as windows.forms.form

But this won't work because of the enormous amount of handlers added to the original.

How can I show my (TextureBrowse in my case) Dialog so other programs can use it?
