.NET Multithreading / Calling Invoke On A UI Control From A Class In A Separate Class File?

May 13, 2011

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.

Make A Class Recognize That An Interface Found In Separate File Exists?

Mar 8, 2010

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]...

Load A Lisbox With Data From File. Save Data From Textbox To File?

Dec 10, 2011

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

Phillip Frank
3/19/1990
3
999-555-8618[code].......

I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

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?

Set Print Properties In A Separate Class?

Apr 18, 2009

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.

.net - Separate Metadata From The Class Definition Across Assemblies?

May 24, 2011

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?

ComboBox + Enter = Ding - Created A New Separate Class Within Project

Jun 21, 2010

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.

IDE :: Partial Class Code Behind A Dataset Object / Is It Running In A Separate Thread

Jan 27, 2010

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.

Asynchronus Output Capture (BeginOutputReadline) Method Doesn't Work From Separate Class In VB

Jun 11, 2012

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

String Manipulation - Separate Three Fields Of The Phone Number And Display In Three Separate Text Boxes?

Feb 23, 2012

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

Create Separate Object Instances For New Objects In Separate TabPages?

Sep 17, 2010

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.

Possible To Have Separate Combo Boxes That Will Give Separate ID Values But Using Same Table?

Apr 30, 2010

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.

Passing Back Lisbox Values When Going Back To Previous Page?

Jul 23, 2009

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.
