I have a form with a tabControl on it. This tabControl has 10 tabs and each tab has multiple textboxes. I am trying to iterate through these textboxes, but cannot find which collection these textboxes belong to within the project.

I'm by far a VB expert, but I've used tabcontrols before without having with happen. VB 2010.I have a tab control element on a form, and on the tabcontrol, tabpage1, I have 21 databound controls that are being pulled from an Access database. Each control has it's own table adapter that is being filled from the same dataset. I also have a save button and a cancel button outside tha tabcontrol on the form itself.
When I debug the app, the forms load correctly and I can see my databound elements containing data. I can click on a single control on the tabcontrol page. Whatever control I click first, such as the gender combobox, becomes the only control I can click on. I can change tab OK, and I can click on the buttons off the tab control (although there is no underlying code for those buttons yet). However I can't click a second control on the form, and I can't close the form without closing the parent form. There is no other code on the trouble form other than the tableadapter fills.
I have this program that should execute a piece of code base on the tab that is selected. How do I do it?I've tried:if tabcontrol1.tabcount=1 then 'Execute this code'
else if tabcontrol1.tabcount=2 then'execute this code end if-But doesn't work, what's the proper way of doing it?

What's really the point in using the former?It's hard to use linq if I used the former. I have to convert that to an array first which is difficult because there is no (asarray) function.I think I would change all of my code that's using System.
Collections.Specialized.StringCollection to System.Collections.Generic.List(Of String)

I am not sure whether it is possible or not? need suggestion.I want to display filenames from 2 different folders into 2 different DataGridview controls that are placed in 2 tab pages of TabControl1. Here is the code that I have tried. By running this code, I can able to show the filenames from a folder onto DataGridView1 in Tabpage1 but not in DataGridView2 of tabpage2.

I have a tab control with two tabs. Both tabs have controls which are unique to them, but there is one control which I would like to always appear on whichever tab is currently active. I figure I just need to add some code to TabControl1_SelectedIndexChanged(). I tried
MyControl.Parent = TabControl1.TabPages(
TabControl1.TabPages.IndexOf(TabControl1.SelectedTab))
MyControl.Parent.Update() ' is this necessary?

View 1 RepliesI am loading forms into a TabControl creating a new tab page each time the form is loaded. ** I would like to point out that I am using UC instead of a from**
Now, I can easily have many tabs with the same form loaded. On the form I have a 'Search Button' So my question is, after clicking the search button how can I tell which instance of the form the 'Search Button' was clicked? Hope this makes sense

I would like to create a customer class and be able to add collections to it. I know I have to use List<T>. Look at the scenario below. I have a customer class, order class and address class. I would like to instantiate the customer class and add orders and addresses to it. E.g.
Dim oCustomer As New Customer("Acme Inc.")
oCustomer.Orders.Add(New Order(1))
oCustomer.Orders.Add(New Order(2))
oCustomer.Addresses.Add(New Address("Street 1"))
oCustomer.Addresses.Add(New Address("Street 2"))

I created a website that contains a Webservice that transfers data to a windows application Using a collection, however, I get this Error that says that anything that inherits the ICOllection, it must implement Add(System.Object)
View 2 RepliesSay I have a interface called IProperties and I have a collection called colMyProperties that is a collection of IProperties. Then I have an object called clsProperty that implements the IProperty interface. Now, in my code where I add objects to the colMyProperties collection I add a bunch of clsProperty objects. so far so good.
Now when I try to access an object in the collection I can only access properties and methods of the IProperties interface, not the clsProperty object. What am I doing wrong? Do I need to cast the object?
Pages have Roles. Users have Roles. A user may only view a page if he and it share one or more roles.
This works:
Dim Allow As Boolean = False
CurrentPage.Roles.Load()
For Each r As Role In CurrentPage.Roles
r.Users.Load()
[Code]...
How can I make it compare only the Role Id values to determine equality?
I have a VB6 project with about 100 custom collection classes which I want to convert to VB.Net. A typical example would be something like.
Class CAccounts
Private m_Accounts As New Collection
Public Sub Add(newItem As CAccount)
m_Accounts.Add newItem, newItem.IdKey
[code].....
All of the collection classes in the project use this standard approach. However, not all the properties/methods of the collection classes are actually used. Most of the collection are used in "for each" loops. Keyed access using the string key is quite common. Keyed access by index is much less common.
Ideally I'd like to take a standard approach to converting these classes. I don't really want to have to review each collection and it's usage to consider whether I need a List, Dictionary, etc. Some of these collection contain 100,000 objects, and some will only contain 10. However, on the other hand I don't want to cause performance problems by using a more complex structure where a simpler option would do.
Sticking with the old style Collection. So, it would be relatively easy to convert to VB.Net But, I'd rather move to the more modern structures.Have CAccounts Inherit KeyedCollection(Of String, CAccount). Fortunately most of the classes held in the collections do have the key as part of the class (eg CAccount.IdKey above). This seems to work well. However, relatively few classes will access the colelction by numeric index. So, perhaps this is overkill if I only want keyed access by the string key?Have CAccounts Inherit Dictionary(Of String, CAccount) for the classes where I don't need access by numeric index. The problem I have with this is that all the existing "for each" loops are like "for each account in accounts". I don't want to have to change all these occurences to something like "for each account in accounts.Values". Although perhaps I can get round this by changing the default property?Have CAccounts Inherit MyCollection(Of String, CAccount), where MyCollection is my own bespoke collection. This seems a bit too much hard work.
Is there a way to create a collection of collections? e.g. I created a collection ListOf(Lines) After I add all my lines to it, I want to store this colleciton in another listOf(Collections). The reason I want to do this is because i want to create several separate collections of lines and I'll need to loop through them all to look for a certain line and I thought this would be a good approach if it's possible.

I'm not sure how to do this but I want to store data in several collections. I want the data to be stored / accessed as follows.

how these nested structures or collections are defined and used?
I'm trying to learn how to work with Collections list. In the past, if I wanted to create a list I would use an array and then save it to a text file after I was done manipulating the data via CSV.how to save things of different types to a list such as:
Name, Birthdate(as date), Salary
I know how to do this in an array but all the synapses aren't firing with the "new to me" collections list as collections lists are hard typed....
