Doing Objects In VB 2005 Project?
Apr 4, 2010
I am hoping that someone from the forum is familiar with the Doing Objects in Visual Basic 2005 book so that this question makes a little more sense. I have completed the sample project and understand most of what I have done. There are some holes in my knowledge but I am sure I will pick up those pieces as I become more familiar with object orientated programming.
The sample project is an almost complete application where you view and edit Objects that are stored in a database. The author leaves the remaining features needed up to the reader, which is great because I have been able to put new knowledge into use. However I am having trouble saving a new object back to the database.
[Code]...
By looking at this code it appears that I can save the data that is in the bindingsource by changing the EntityState to the Enum added. However I am not sure where to set it. I am pretty confident that I have the rest of this correct because when I try to do the save I get an error that the stored procedure is expecting the GoalID.

I am hoping that somebody here is familiar with the book, "Doing Objects with Visual Basic 2005" so this question makes more sense but I will try and ask it in a way that makes knowledge of the book irrelevant.The book contains a sample project that I am trying to use as a "framework" for all my new projects. The project shows you how to read and edit objects to and from a database and that part works great. The author then leaves the new and deletes up to the reader to do, which is a good way to learn. However I am having trouble with the it. My problem is that I am having trouble implementing my own ProcessNew InterfaceI think this is how it should be:
Public Function ProcessNew() As Boolean Implements IMDIChild.ProcessNew
Dim myGoal As Goal = TryCast(GoalBindingSource.AddNew, Goal)
myGoal.Goal = rtxtGoals.Text

I have two lists declared as follows:
Dim lstDBItems As New List(Of DBItem)
Dim lstAppItems As New List(Of AppItem)
I am trying to do something like this:
I've a function which returns List(Of AppItem):
Function GetAppItems() As List(Of AppItem)
'...
End Function
In the above function I populate lstDBItems and then write the return statement like follows:
Return lstDBItems.Select(Function(x)
dim oItem As New AppItem()
oItem.Property1 = x.DbProperty1
[Code]....
The weird thing is the code compiles, but on rumtime I get a type case error.

Is there a tool to convert a VB.NET 2005 project to a C# 2008 project. I am trying to convert our project to VS 2008 and mostly port all the vb.NET code in some projects to C# 3.0/3.5.

Silverlight project with tabcontrol hosting canvas objects. I want to wrap my entire tabcontrol with a scrollviewer so that on a short display you can scroll vertically to see the whole area on my canvas.When I run my project my scrollviewer vertical bar is always showing even when there's more room vertically than needed for a scrollbar.
All I am trying to accomplish here is a min resolution of 1280x768 to be scrollable and anything bigger than that have the scrollbars hide. My laptop is only 768 tall, but my canvases were developed with 1280x1024 in mind. So I would like a way to set this up so that everyone can scroll or just see the canvas all at once depending on their resolution.
Anyone have any ideas why it is always visible? I've tried setting canvas width and height. I tried setting stretch on alignments on the outer grid. Saw both those tips while searching other issues similar to mine.
Some code:
<Grid x:Name="LayoutRoot" MinHeight="768" MaxHeight="1024" MinWidth="1024" MaxWidth="1280" Background="#FF6A6868" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.775*"/>

....lots of child canvas items in my "Main Floor" canvas. Child canvas objects contain lots of path objects. None which are taller or wider than the main floor canvas width/height.
<sdk:TabItem Margin="0" Header="Mezzanine">
<Canvas x:Name="Upstairs" HorizontalAlignment="Left" Height="1000" UseLayoutRounding="False" VerticalAlignment="Top" Width="1280">
..another tab. Same deal with child canvas objects.

I have developed a small window application, having lot of insert and select scripts. It runs fine for 3 times but when i run it 4th time it gives me Error "Out Of Memory Exception". I observed that in my task manager Sqlserver.exe process occupies memory around 167000K. Then I killed it. and again run the code, this time it occupy 12000K memory. Again I run it...the memory increases and stops at 87125K. All It means i the C#.net objets are not disposed well.
I have tried for
GC.GetTotalMemory()
But failed? How can I release objects?

I was working on one of my forms, not doing anything crazy or out of the ordinary, just adding a control to the form. When all of a sudden vb became real sluggish and barely responsive, so I closed VS and restarted the computer. Got back into my project and now I can't open any form. Opening a form gives me <b>failed to parse method 'InitializeComponent'. The parser reported the following error 'Error HRESULT E_FAIL has been returned from a call to a COM component.'. Please look in the task lisk for potential errors.</b>.Error list sometimes contains 102 errors, and sometime just one that says I have exceeded the maximum number of errors. When it contains 102, every single one of the errors is <b> [Object/Form] is ambiguous in the namespace [Project] </b>.
I can't open any designers right now, every single one of them gives the failed to parse method error. If I rename, lets say frmAbout to frmAbout1, then I can see that form.There is only one of everything in Solution Explorer, no duplicates. There are no duplicates in the folder either. I can open the code for each form/object and see it just fine, and looks fine too. Code is not duplicated or anything.

How do I fix this error in Visual Studio? "The project file cannot be loaded. The application for project ... is not installed" I have copied a whole project onto my PC, both into My Documents/Visual Studio and into inetpub/wwwroot, but when I try to open the project in Visual Studio, it tries to open just 1 file .vssproj and gives me error messages, like : "The project file cannot be loaded. The application for project ... is not installed.". What am I doing wrong? The VS edition is 2005 as are all the projects aI am trying to load.

I had made a project in VB.NET 2005 with SQL SERVER 2005 used as database. Now i want to make a setup of this project but i am unable to integrate sqldatabase and .net framework in this setup project. Is there any way to do this. Because it is assumed that the client does not have .NET Framework installed nor he has SQL Server on his system and the worst condition would be he does not have even internet connection from where these two setups can be downloaded if we give the condition for downloading these programs from the net if the client does not have these programs installed on his machine.

I'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.

I'm not real sure how to even ask this question... but here goes.I'm using VB2005 and DirectX 9, D3D. It is 2D isometric display.Here is what I CAN do. Create a map grid. Draw each tile out and present the map on the screen. (ISO) I can even scroll around using the arrows and mouse at the edge of the screen.
- I can click on the map and get the X,Y coords of the tile I am on.... look up the grid to see what is supposed to be on this tile.The only game coding experience I have is using windows forms controls... I've done a few dozen of them. Dice games, card games..

I have a windows form application and also a exe application that both uses the same dll whic I place in the bin directory The dll is using crystal report and thus I need to reference com objects and other .net drivers. My question is following: Where should I put these references, in the class library (dll) or in the windows form / exe applications. If I put them in the dll, will they automatically be loaded when call the dll (entry point) or do I need to something else (create in installer etc)

Have a windows application that "got complex" and new products could use many portions of the existing application.Decided to break app into multiple projects to facilitate sharing the appropriate pieces with new products.One object in app provides a library of text phrases used in the production of output docs.Wondering if such an object should be a set of shared methods instead of instantiating it in every object that consumes these text phrases.

I am not sure if this is the correct place for this, but am using a custom control in a project that I want all the developers to have access to when they download the source.
Should I just add it to the project like a normal file? If so how do I reference it in the project folder? The other developers project folders might have different paths than mine.
