User Control - Failed To Create Component (Out Of Memory)
Nov 3, 2011
I am working on a user control. Embedded in my user control is another user control. All of a sudden while programming some simple stuff I get an "out of memory error message". I can no longer load my project (after reboots etc.). I start a new project, copy the control.vb files into a new project folder.. add then add the control to the new project. Ican view the design and the code of the control. When I attempt to drag the control onto another control in the same project I get an error message
"Failed to create component... 'system.outofmemoryexception. Out of memory".

I recently changed from vb 2008 express to vb 2010 express and converted a project I was working on to vb 2010. After conversion I added a lot of code and all worked well. Now I want to add some shapes from the vb power pack tools and I get the following error:
---------------------------
Microsoft Visual Basic 2010 Express
---------------------------
Failed to create component 'OvalShape'. The error message follows:
'System.InvalidCastException:
[A]Microsoft.VisualBasic.PowerPacks.ShapeContainer cannot be cast to [B]Microsoft.VisualBasic.PowerPacks.ShapeContainer.
Type A originates from 'Microsoft.VisualBasic.PowerPacks.Vs, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' in the context 'Default' at location
......
How can I recover from this?

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I have created a windows form based application and I want the form to add a user specified amount of user controls (with textboxes) on to a panel. The user can then click some button and the controls on this panel are cleared and new ones are added. The user does something and the process is repeated. Now, I wanted these textboxes to support spell checking and looked all over for a free solution.
WPF textboxes support spell checking where the ones in regular win forms do not. I thought I would be able to use these WPF textboxes by adding them to an ElementHost object which is, in turn, within a panel. This panel would be a user control.
So, in my application, I would be able to add instances of these user controls onto the form and make use of .NET's spell checking goodness. This actually worked but after using the application for a while, found that the application would eventually freeze on me due to out of memory errors. I have pinpointed the memory errors to these WPF controls since this problem does not happen with normal textboxes.
When the window is opened and the number of controls is specified, this is pretty much how the controls are added:
Dim xOffset As Integer = 0
For i As Integer = 0 To theNumber
Dim myUserControl As New SpecialUserControl()
[Code].....
There are a lot of results on the internet when I tried to find a solution and I'm thinking that the problem I am having is due to the fact that the WPF control is not going away even after clearing the panel. Following this conclusion, I have tried different solutions regarding disposing these controls or setting them to nothing but the memory problem keeps occurring.

I am using msn api to read contacts out of msn
Interop.messengerapi.dll
When I run the app on my machine everything works perfect. But when I run it on another machine, the following error appears:
Creating an instance of the COM component with CLSID {B69003B3-C55E-4B48-836C-BC5946FC3B28} from the IClassFactory failed due to the following error: 8007000e.I have merged the interop messenger dll properly with imerge, so that cant be the problem.
Also a memory problem must be out of the question. I only use 300mb from the 4GB. There is also enough disk space available.
My Code:
Private Sub getMSNContacts()
Dim objMSN As New MessengerAPI.Messenger
Dim msncontact As MessengerAPI.IMessengerContact
Dim msncontacts As MessengerAPI.IMessengerContacts = objMSN.MyContacts
For Each msncontact In msncontacts
ListBox1.Items.Add(msncontact.SigninName)
Next
MsgBox("getMSNContacts")
End Sub

1. Open the the dataset.xsd from the solution explorer.
2. Right click in thedesigner and add Tableadapter.
3. Click the Next button twice to get to the "Enter SQL Statement" and click "Query Builder" button.
First Error Message: "The Query Builder Faied..." "The Parameter is Incorrect" Click OK and click the "Query Builder" button again...2nd Error Message: "The Query Builder Failed..." "Attempted To Read Or Write Protected Memory.This is often an indication that other memory is corrupt."
This one particular dataset has been editied a number of times. Furthermore, in this project, I now get this error in all three (3) datasets I have in the project. Is there a way to start a new prject, import the form andf class objects and create an entirely new set of datasets? I've tried this with no success.

When I try to create an Inherited User Control everything goes fine until I specify the base control and press "Add" in the Inheritance dialog. The code in the newly created Control should have a "Inherited From" statement, but it doesn't and nothing works after that. I even tried following the ctlClocklib project and the same thing happened. ctlAlarmClock.vb was created but the "Inherited From" statement was missing.

I'm trying to create a generic ListView user control that can be used over and over again in different projects. I've got all the basics done but I want to be able to act on click events in the from not the user control. In other words if someone right clicks on the listview, for example, I want the form to know it and be able to act on it.

I want to create a User-Control that inherits the functionality of a TabContol.
I begin by starting a new project of the type Windows Form Control Library. Next I place a TabControl on the UserControl designer surface and Dock the TabContol to Fill the UserControl.
I go to the code editor for the UserControl and enter the following line of code.
Inherits System.Windows.Form.TabControl
Then I run the program and get an error. Intellisence recommends that I use one of two recomendation. When I accept the recommendation I and try to run the program the problems esculate.
The design-surface is no longer accessable.
I try to comment out the problem lines of code in the UserControl1.Designer.VB file but that doesn't help.
How can I create a UserControl that Inherits the Properties of the TabControl so that the properties of the TabControl are visable in the Properties Window?
