Can't Build UserControls Under X64
Mar 30, 2012
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'm trying to build an application to monitor a site to build statistics from the data being read. This HTML looks like this.
<div id="history">
<h4>HISTORY</h4>
<table border="0" cellspacing="0" cellpadding="0">
[code]...
Now I can read the html and put the text anywhere, I just don't how to read specific parts so I can separate the data out.

I have a Form with a Media Player in it. Which plays a Song.
[Code]...
It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.

A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?

I have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?

I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

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 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 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">

When we create an inherited control then is the Designer still needed or not? Should usercontrols be disposable?What is the difference of using Base and Me when we are setting default properties of our usercontrols?[code]

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?

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 have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.

I'm having a bit of trouble with creating one of my custom controls. What I've got is a listbox within a usercontrol, and I need to be able to click on the lists items while still in the designer. This would make it act much like the tabcontrol.

The trouble I'm having is working out a way to be able to call the objects in the dynamically created usercontrols. I thought a list maybe an option but I am struggling to get the syntax/get it working. Wondering if anyone has some ideas or different approaches..

I have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?

I have a custom VB.NET control that I created that is working correctly in one program but not in another.The control has one button and one form. The form displays some data based on the settings in the control.
[Code]...
In TestProject1 - the control is working as expected In TestProject2 - the control is not sending any of the settings I set to the form My control works fine when I debug with the UserControl TestContainer.
I am using VB.NET on VS2005. This is all done on the same machine. Why would this work in one project and not another?

At work we have a pretty large web application that works by having a few pages, with lots of user controls which are nested in these pages. This is working fine most of the time but we have a problem at the moment where one of the user controls isnt working. Originally it was referenced from another project in the solution but when this wasnt working I decided to copy the file into the project and try to register it locally. It works on our development system, its only when we move it to deployment that it stops working, and I'm thinking it's something that I'm missing in the build. When you go to the page on Live the control is just missing, and no errors are generated.

I want to be able to show a different usercontrol in a single container depending on a criteria, something like
Quote:
if a = 1 then
show usercontrol1
else if a = 2 then
show usercontrol2
etc
I could add all of them at a time and just tweak their visibility per each case but is that the best method for such task?

Using Visual Studio 2008.I have been coding for some weeks with a problem whereby if I try to open a certain UserControl in the Designer, I get many errors, all saying the Class of one of the Controls on the Form does not exist.If I rebuild the project, the IDE realises that the class DOES exist and will then render the form for Designing. This has never been ay problem at Runtime.Now, however, if I try to open that same UserControl in the Designer, Visual Studio crashes, sends an error report and restarts.Visual Studio gives me no error report or advice.What can I do now? I need to get to the Designer.
