Notifyicon As A Separate Class?
Feb 11, 2011
I don't want my application's main form to be displayed when it opens; I just want the notifyicon control in it to show in the taskbar.This is the code I have been using:
Module:
Code:
Module mdlStartup
Public Sub Main()
[Code]...
The NotifyIcon control is in my frmMain. However, when I run my program I get mulitple instances of the Notify Icon being displayed. I even get two frmMains getting launched if I try clicking the other tray icon that has been made. I'm guessing this has to do with the New instance.If that's the problem, is there a way I can move the notifyicon control to some completely separate class?

Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

Good evening folks, I'm building a program that is threaded. While I can get the thread to work no problem, I can not seem to add pages to my tabcontrol from the class I'm using. Any idea's on what I'm doing wrong?frmMain is loaded first. Then the idea is to load the other tabpages using a separate thread as they take awhile.[code]

I'm writing a program and rather than having all the print properties in the main form I'd like to have them setup in a seperate class. I've done printing before by setting all the properties in the form where all the controls are located with no problems but this has me stumped. Reason for doing this is just to try and organize the program a little better and there are several areas of the program that will have different data and format to print so this will cut down on having potentially hunderds if not a thousand lines in that one area. I can't imaging that this wouldn't be possible.

I'm working a business layer (separate assembly) that will contain various business entities used in multiple client applications. One of the client applications is a WCF app that will need to serialize these entities. In order to properly serialize the entities, metadata for data contracts or for XML serialization must be added, but the serialization requirements may vary across applications.
Clearly I need the metadata separated from the class definition. So how do I add metadata to my entities for each separate application?

I need to be able to access a progressbar in my form from a separate class.
I tried
Dim Prog as Progressbar
Public Property Pg()
Get
[Code].....
I need to be able to access a control from a separate thread and return to the thread again.
Edit: Its just an example I gave prog a value of the object from the form and the invoke required is put in a sub so thats not my problem.

I didn't think this would be a problem, but it appears that others also search for this solution. There is an annoying DING! when hitting the Enter key in a ComboBox in VB.Net so I sought solutions. Here is the solution I am working with. I created a new seperate Class within my Project...
Public Class ClasscboBox
Inherits ComboBox
[CODE]...
Looks good, but I am having a problem calling it from the main project. Here is what I have tried using...
Dim objcboBox As New ClasscboBox
objcboBox.OnKeyPress(KeyPressEventArgs)
However, it says thatKeyPressEventArgs is a Type and cannot be used as an Expression. I tried 'e' but no go. I am a little ahead of my classes (no pun intended) so I am likely missing something about what I am doing wrong.
I have three comboboxes so I though this would best suit my needs in the interests of writting decent code and not populating each call with repeating code.

I've been searching for the answer for a while but can't find it yet. Basically so far I have a simple VB.Net form with one button.I would like to make a class or module that can handle events from the main form. This is my code so far but it doesn't seem to work.

I am instantiating a form object in my code behind the dataset just to access some form level variables and to occasionally set a label in the navigator bar. Recently in the b2 Team version of VS2010 there are some strange errors thrown in the immediate window and then I'm tossed out of debug mode and back into the IDE. This code has been operating for some time in this project without this behavior. A team member has just reproduced the behavior in his development machine also.The error that starts the shutdown of the debug instance is this: Control accessed from a thread other than the thread it was created on.

I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?[code]...

I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

I'm currently coding a multi-form project that requires a NotifyIcon. The first form is the Login form which then opens a 'logging-in' form and then finally another form (they're all opened using FormName.ShowDialog() and they hide themself before opening the next form).Login Form -> Logging In Form -> Final Form.When the final form is opened, the NotifyIcon's visible property is set to true and it appears in the tasktray like normal. But when I use Me.Hide on the final form, the NotifyIcon disappears with the form.Any ideas about what is going on? The program still runs in the background despite no forms are visible (which is how it's intended to be) but without a NotifyIcon, there's no way of making the forms appear again.

I have a NotifyIcon in my system tray.
When my app closes, the NotifyIcon is still there until I run my mouse over it.
How can I make it go away when the app closes?
