VS 2008 - Shadow The Item Property Of My Collections To Retrieve The Actual Data?

Oct 6, 2010

I am trying to solve an issue in my application where the following exception is occurring: there is already an open datareader associated with this command which must be closed first. I am using TableAdapters, which maintain their own DataReaders, and everything seems to work fine unless I am interacting with one of my background workers.

In my code, I shadow the Item property of my collections so that I can retrieve the actual data from the database if needed. Here is a sample:

[code]...

Now each reference to the Item get property instantiates its own DataAdapter, so I am confused as to how the same DataReader will ever be used in this scenario. Is there something I am missing? All the TableAdapters do in fact use the same connection object, but I wouldn't think that would be a problem

System.Collections.Generic.Dictionary `Add` Vs Set `Item`

May 20, 2011

If i wish to put items into a System.Collections.Generic.Dictionary, I can either Add or set the Item.I know if you do Add it helps you check if the key already exists and if not it throws an exception.Now I'm curious, so if I'm adding a ton of items, should I prefer setting Item instead of Add since Add does unnecessary checks that may actually slow things down?

Which VB Remote SQLServer Access?

Dec 23, 2010

I have a web site that connects to a remote SQLServer, and is running just fine.I have some pretty simple 'batch' type tasks that I want to run (as a Windows application) on a scheduler (I'm more comfortable with VB so I prefer that).

Looks like VB Express won't allow me to access the remote data. Everything seems to be pointing to having to buy VS Professional for $545 (I don't have an original one to upgrade). Is there a more economical VB option?

Converting A VB9 Application From Using Access DB To SQLServer

Jun 26, 2009

I have been developing a VB 2008 application which has been using Access as its database. The app is very far a long with about 30 forms and 45 DataSets I now must change the application to use SQLServer. Unfortunately all of the Table & Attributes names have changed in the new DB. Almost all of the data model has stay the same.

I have a few questions on the conversion.

The ConnectionString is currently pointing to the Access DB. I have entered the new ConnectionString into the Setting tab. What is the best approach to make the change?

I have done some testing to change the Table & Attributes names by using Quick Replace. It seams that sometime when I would do the rename I would lose the TableAdepter on some screens.

What is the best approach to performing the renaming task?

IDE :: VisualStudio Property Toolbox Not Remembering Last Selected Property Item

Sep 1, 2011

I have a weird question and I honestly hope you understand what is happening here: I design my form (using VB.NET) and put on it a few textboxes, comboboxes and a listview. After the design, I want to adjust the TabIndexes for each control on the form. On the right-hand side of the interface is the property box.

I then select the 'TabIndex' property item and enter a number key (for instance 0) for that selected item. I then select the next textbox control and enter the next number (for instance 1) WITHOUT re-selecting the 'TabIndex' property item. As soon as I select the combobox or listview control, the currently selected property item jumps to 'Items' or 'Collections' and does NOT remain on the 'TabIndex' property item. Why is this happening? Everything worked fine and all of a sudden this starts happening. Should I reset the editor settings or how can I resolve this matter?

VS 2008 - Property Grid - Click On Item Show Its Property

Mar 18, 2009

I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.

When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.

C# - Set The Binding Of A Item Template Item To User Property?

Oct 21, 2010

I have a simple user control, which is essentially just an AutoCompleteBox with some custom logic.

For a specific instance (a collection of Persons), I want it to look like this:

<sdk:AutoCompleteBox Name="myACB" ItemsSource="{Binding People}" FilterMode="StartsWith" MinimumPrefixLength="2" ValueMemberBinding={Binding LastName}>

[Code].....

I want the DisplayMember property to be the property name to display for whatever kind of custom collection (persons, cars, etc) I have bound to the AutoCompleteBox.

I don't think I can modify the datatemplate programmatically. Is there a way I can do this with binding (relative source)?

Automatically Recognize And Handle Changes Of An Item In A "System.Collections.ObjectModel.Collection"

Feb 4, 2011

I wanted to create a custom control with a custom Item-Collection in it.(Similar to the ListView Items, but with other properties)I wrote a Class that holds properties of a single Item data (ClassItemData) and another class that "Inherits System.Collections.ObjectModel.Collection(Of ClassItemData)". The Collection class contains a public event (ItemCollectionChanged) which is raised when "ClearItems", "InsertItem", "RemoveItem" or "SetItem" is called. (I used "Overrides" on all these functions and added the Raise Event to them.) The event is handled in the custom control itself and causes the control to refresh/repaint itself. The collection class contains also "Default Public Overloads ReadOnly Property Item(ByVal index As Int32) As ClassItemData" which returns the Item at the speciefic index.

The control refreshes itself when I place the control on a form and use code like: ControlName.Items.Add("TestItem") Unfortunately the control does not refresh itself when I use: ControlName.Items.Item(0).Visible = False The value of the Item itself has changed after this, but the control does know about the changes and does not refresh itself. If I do a manual repaint/refresh of the control, it looks all fine, but it does not work automatically. Does anyone know, what I have to add, so I can handle an event or something in the control when a property in the ItemData class has changed? How do I recognize changes in existing items and raise an event in the custom event?

Can't Set The Name Property For The Timer Control At Runtime?

Feb 3, 2010

I am relatively new to programming and have managed so far with google and a lot of patience! I am having a problem naming timer contols at runtime. This is what I am trying to achieve.

1. I connect to my dataset and to my first record

2. I create a loop for the recordset

3. I create various objects on a form and name them using the info in the dataset

I also need to create timers and name them using the first field of my dataset. It needs to be dynamic as its database driven. There could be as many as 100 timers at any one point.

Runtime Error '380':Invalid Property Value

May 2, 2006

A VB5 program I wrote years ago stopped working and is now giving me this error:

Run-time error '380':Invalid property value

I cannot figure out what has changed, since I run that program almost daily. It was working fine, then stopped (without any changes to the program). I suspect I may have uninstalled something it uses, but cannot figure out what.When I open the VB5 IDE, I get an error saying:

'c:program filesdevstudiovbComct232.ocx' could not be loaded--Continue Loading Project?

If I say no, it does not load and I cannot see the source code.If I say yes, it does load and I can see the source code but I get weird compiler errors.
