ASP.Net - Accessing Controls From Separate Classes?

Jun 23, 2010

I have an ASP.NET Web Site I am creating in Visual Web Developer 2008 Express using Visual Basic as the language. It is actually a rewrite-with-mods of an existing ASP script and I'm trying to chew what I've bitten off. I created my page with a text box (txtOutput) on it and since the end product is very complex, and it's generally good practice to separate like functions, I have created 4 separate classes in the App_Code section. My main page is Sync.aspx and has a code file Sync.aspx.vb with it. One of my code files is SyncDatabases.vb and in it I have created

Public Class SyncDB

In that class I have created some routines such as

Public Function ReadMSDB(ByVal SQLString as string) as Boolean

In this routine I want to put information in my text box txtOutput on the main form (the default - Form1).

My problem is that if I try:

Form1.txtOutput.Text = "Hello world"

or just

txtOutput.Text = "Hello world"

it says Name 'Form1' (or 'txtOutput') is not declared. I am sure I am missing something simple but have no clue what it is. I assume it's the fact that the write command is in a file (class?) outside the file (class?) containing the page itself but I don't know how to address it properly.

I have coded two seperate VB.net windows forms application as two seperate projects in seperate solutions. I now want to combine one project called "Reporting" into the other project called "AnalysisApp" and be able to call the Reporting apps main form.The Reporting app utilies a whole load of controls from DevExpress which are not included in the "AnalysisApp" I have added references in "AnalysisApp" to the DevEpress controls and also to the Reporting app, as well as combining the Reporting app into the same solution, but when I build the "AnalysisApp" it fails saying that it cannot find the DevExpress DLLs

Storing Classes In Separate Files?

Mar 18, 2012

In Java you can store a class in a separate file and instantiate it from a method in another file as long as the class file is in the same directory but this doesn't seem to work in Visual Basic.

Three Classes Running As Separate Threads?

Nov 21, 2006

I want to have three classes running three simoultaineous threads. I have started out with one class that looks like this:

Imports System.ThreadingPublic Class C_EventCollector Dim oThread As Thread Public Sub New() oThread = New Thread(AddressOf Me.BackgroundProcess) End Sub Private Sub BackgroundProcess() Console.WriteLine(Now.ToString) oThread.Sleep(10000) End SubEnd Class

What I want is execute BackgroundProcess() every tenth second. For testing purpose I print out current date and time to the console. Using this thread BackgroundProcess() only executes once.

Forms :: Multi Threading With Separate Classes

May 7, 2011

I'm trying to dive into what I consider a deeper end of VB.net to see how far I can go with it. I have a project created, ironically called "My First Server". The aim of this is to create a server which can handle multi clients but additionally isn't the commonly shown tutorial setup of a console application. So it is created as a Windows Form application. The main form (Public Class PrimaryForm) consists of only one control which is a listbox control. This is named LogOutput.

Accessing Instances Of Classes

Jul 25, 2011

I am trying to make a pretty complicated, layered program.I have my main form which creates an instance of another form (addValue and myAddValue). From myAddValue I then want to access a few other classes to do various verification and other bits of code.Here though I have a problem.With the form ContactDetails, it just can't seem to read myAddValue.txtName or the others.If I try and read AddValue normally it says about it not being able to access a non-shared member (Expected that this doesn't work, it was just an attempt at something different)How do I read myAddValue from a class which isn't the one that created and isn't the one that it is an instance of?

Accessing Objects From Other Classes In ASP.NET

For instance I have a class named AbleCommerce that does some database functions. These functions are called from my main class.

Asp.net - Accessing Values From Partial Classes?

Sep 2, 2011

I'm still learning so this might be completely wrong. I have built a multi-user web application for internal purposes. I have split my code up to make it more manageable and have run into some problems. I suspect that I have done something very silly!

I have a class in a separate file (quoteStatus.vb) in App_Code here it is:

Imports Microsoft.VisualBasic
Imports System.Data.SqlClient
Imports System.Data
Public Class quoteStatusHelper

[Code]...

This seems really wrong, as the value seems to be held in the partial class after the first run. So if I have two users accessing the class the public shared dim is changed for both users! There must be a better way to do this. I have looked everywhere and I'm more confused now than when I started off..How can I make QuoteStatus in the partial class unique to every user and access it from my code.

Accessing About 100 Sites At Once Use Classes Or Subs For Each Site?

Mar 1, 2012

I have about 100 websites that I am going to be accessing to scrape some data from (weather, time, etc). When I go to code these babies there will be an abundance of sub routines that I will be creating. They each are going to be accessing pretty much the same type of data.

Should I put them into a Class some how and acces them that way or should I just use Subs and then call them into the Document Completed section of my web browser to run the code? Still sort of confused on the whole Class vs. Sub Routine thing.

Forms - .net Controls In Separate Files?

Aug 8, 2011

VB.Net Windows forms feature controls that are often dragged from the toolbox onto the form. The code for the control goes right into the form. Usually this is great, but is it possible to write the code for a UI control (like a panel) into a separate file which can then be imported or otherwise included into the main Form Class?

Context (a.k.a. long version): I have a form with an unchanging column of navigation buttons on the left hand side. The rest of the form is taken up by different panels, which in turn have different controls of their own. Clicking the different buttons on the left should cause these different panels to appear (clicking button "A" brings up panel "A"; button "B" brings up panel "B", etc.), but the left-hand menu should stay unchanged.

I'm having a hard time implementing this design in an elegant way in VB.Net. If I make each panel a separate Form, I have to duplicate the code that builds the unchanging left-hand menu in every file, which is terrible. I tried using inherited forms so the separate panels would inherit the left-hand menu from a master form, but that means each click on the menu sprouts the new form in a new window, and although the left-hand menu is inherited, the menu that I clicked and the identical-looking menu in the new window are not the same objects in memory and have no knowledge of each other.

I just want one window with central content that changes based on what you click on the left-hand side. A solution to this would be for the panels to be just that - panels - and not separate forms as I'm currently doing it. But this gets messy organizationally because the code for all of the panels has to be in the one massive master file. Hence the short form of my question (see above): How can I code a panel in a separate file and then bring it into the fold of the main form?

How To Place ASP Custom Controls In Separate Tab Panels

Dec 23, 2011

I have a asp.net placeholder which gets populated with many custom controls, each custom control is a summary of a location containing various facts and interactions. When directly populating the placeholder with the controls they get added one under another down the page. I'm trying to find a way to place each custom control generated in a loop in its own tab (any sort of tab, asp.net/jquery ui etc) so that the user can select the summary they wish to view instead of having to scroll down the page to find it. (I'm using ASP.NET and VB.NET)

Forms :: Looping Through Controls - Design Can't Be In Separate Panels

Oct 21, 2009

I am familer with looping thru controls like so:

[Code]....

Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

Accessing Controls On A Panel Without Using Control Arrays?

Mar 2, 2010

I have an application that has a grid of rich text boxes on a panel. I would like to access and modify the text in the various rich text boxes during run time. I know this has been brought up a bazillon times over the years, but I would have done this as a series of control arrays in VB 6. Below is a simplified representation of how the textboxes would appear in a panel if control arrays were availble:

rtbA(1) rtbB(1) rtbC(1)
rtbA(2) rtbB(2) rtbC(2)
rtbA(3) rtbB(3) rtbC(3)

I find that I can access the properties of the rich text boxes via panel1.controls.item(x).text, for example, where x is the control index assigned by the panel when I dropped the controls on it.

Since I created the rich text boxes at design time and dropped them on the panel, it has arbitrarily assigned the index values, and they are not in the index order that I would desire.

How does one re-assign a control's index at design time for a controls collection on a panel? And if one has 24 text boxes on one panel, is there a way to break them into subgroups, such as rtbA(), rtbB(), rtbC() with their own index values?
