lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?

I'm not sure if this is a bad way of building an application but let's say I have 30 WPF Windows for different screens in my application. I want to build them into a DLL so I was wondering if it is bad design to instead of creating each window as a window, if i can have 1 window that hosts whichever screen is open. So the windows will actually be a usercontrol, or at least act like one. So when you want to go to a different screen, you would just change the content of the 1 window to the content of the "usercontrol" that you want displayed.

I am trying to troubleshoot a VB.NET project that contains UserControls (actually, several of them that are displaying the same issues). I am trying to get them to build under x64, but it is impossible. In x86 or AnyCPU, the UserControl builds and shows up in the Toolbox, so I can add or modify it in the forms that require it. In x64, the controls disappear from the Toolbox, I get warnings during build (the current project builds though), I can't see any of the forms - I get errors (please see below) - and projects that require the project with the form as an import will not build.
When I was studying what these UserControls are so that I can maybe rebuild them from scratch, I downloaded code from a book - great learning tool, but I get the same errors[code]...

I also set a reference to the dll file of the library, but still I don't the UserControl in the TooBox.

I am working on a project and there are about 30 controls that I need to call and update at runtime. I have named the controls day0 - day35 (it is a calendar). Basically, at runtime, I need to call each control's setDate function to display the day number. When I run it, the array just has null/empty.This is the array I am trying to use in the code behind. The controls are names day0-day35.
Private dateArr() As ucMonthDay = {day0, day1, day2, day3, day4, day5, _
day6, day7, day8, day9, _
day10, day11, day12, day13, day14, day15, day16, day17, day18, day19, _[code]....
When this gets called, I get a null pointer exception.I do not understand why the controls are not in the array?

I'm a "Moderate" skill programmer, and am upgrading some software I've written in VB.Net (VS2008, .Net 3.5), and need to be able to accomplish the following, which I'm not sure of the best way to go about doing: The software is an information reporting dashboard for a call centre. I have a csv file being created about every 10 seconds, extracted from the telephone software, the file consists of a list of "Skills" (basically telephone line types), the number of calls received on those lines, and the number of callers who hung up (and a few other bits of information I need, but once I figure the basics out, the rest should be easy), basically looking like the following:
[code]...
I need to be able to read this csv, store the data, filter out the "Skills" to be report on (i.e. 1,2, and 5 only), add up the "Offered" and "abandoned" data associated with them and then display this information as one number (i.e. "Skills 1,2,5 - Offered: 4925, Abandoned: 13") (and then the same for the other "Skills"). This data could grow as more phone lines are added or some are taken away.I've got the code to read the data into an array working, but I've got stuck with how to filter and add up the data. I'm not even sure if I can do this with an array.

I created an item user_control that has a textbox, button, etc. which will intentionally collect the total quantity of items the user wants.
I dynamically create a few intances of user_control on page_load. If you click the add button for the item quantity it will add to a session variable. however when the user enters a different quantity in the textbox and clicks the add button the total is of the original value of the textbox.
How to get the value the the user has typed in to the textbox to add to total???
I've create a stripped down example below: [UserControl] [Page] [CodeBehind]
UserControl...
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="BomItem.ascx.vb" Inherits="DynamicUserControl.BomItem" %>
<style type="text/css">

i've been trying to use customcontrols made in vb.net 2008 but when i try to add them to a vba form using
Dim x as new MyCustomControl.Usercontrol
Me.Controls.Add(x)
it returns "activex can't create object" The control itself has nothing special, it's just random textboxes and a few buttons. why i can't use the control?
Edit: TLB has been addeded on references.

I am having difficulties initiating the 2 usercontrol. The first one works perfect but am not quite sure how to get the second one to initiate.
Code for Custom Tabpage Class
Public Class TabPageEx
Inherits System.Windows.Forms.TabPage
Private WithEvents uc As New UserControl1
[Code].....
Now, I am struggle on how to inititiate the second usercontrol still using the TabPageEx Class. Do I need to make another seperate Class Such as TabpageEx2 too handle usercontrol2? The usercontrol2 needs to happen on form load so that the tab is always present.

I've bound a lot of controls on a form to a Entity. Some of them update fine, the others are just jumping back to their original value as soon as it loses focus.The old data are loaded in all controls perfectly.
Dim Q = From e In EnData.Calls Where e.CallID = ID
TempRow = Q.FirstOrDefault()
ticTemp1.DataBindings.Add("Value", TempRow, "CallDate")
ticTemp2.DataBindings.Add("Value", TempRow, "CustomerID")
How can this be fixed?

I have a form with a couple of multi-line text boxes, a couple of radio buttons, and a couple of check boxes. When the form is closed I need to save the values of the textboxes, radiobuttons and checkboxes so their values will be retained next time the form is open. I've done this in VB6 on form open and form close, but I cannot get the same module to work in .NET
Here was what I used in 6.0 to save:
Sub SaveFormState(ByVal SourceForm As Form)
Dim A As Long ' general purpose
Dim B As Long
Dim C As Long
Dim FileName As String ' where to save to

I have multiple controls on my form. Text boxes, radio buttons, check boxes, etc. Is there a way to move through every control on the form and save it's value, status ? Like whether the radio button is checked, or not. The value of the text box, and save them all to a text file. Then, reload the values saved in the text file in the same sequence. Without doing all this one line at a time.
