Would you advise me on what would be the best way to modify tables behind an existing vb.net 2008 desktop application:
1. Would you use refactoring? If so,what methods would you use ?
2. Would you modify an existing D/T diagram using a D/T designer? If so, do you have directions on how to use a D/T designer?

I've included an MS Access database in my WPF VB app, and I'm trying to link the data to an XCEED Datagrid. I have the following code in my testerDataSet.Designer.vb file which I assume is the funcion I should be referencing
Public ReadOnly Property Contact() As ContactDataTable
Get
Return Me.tableContact
End Get
End Property
I'm trying to get it to fill my datagirid using this
<Grid.Resources>
<xcdg:DataGridCollectionViewSource x:Key="cvs_contacts" Source="{Binding Path=Contact, *Source={x:Static testerDataSet}*}"/>
</Grid.Resources>

What I'm trying to achieve is for the datagrid to display the data in the Contact datatable.

My project gets rather big. Now sometimes when loading the design file I get this error. But the project compiles without any problems and runs fine. Some one any idea where to start or what to do?
View 4 RepliesThis may take some explaining but the concept is pretty simple. A user will select a file which contains data that they wish to extract from, so keeping it simple they pick a file like so:
[Code]....
So, I need to show the user the file, allow them to select a line to match and/or extract from. So they select the first line ready for a match, they then select a word/s to mark as a constant for matching, so in this case it would be: MyGroup A simple version for text match would be like "MyGroup *" Now, I need to convert this to regex dynamically (I assume its the best method), its not a one off, the data that is selected is all open and up to user selection. There could be multiple selections and multiple extractions on the same line!

I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
View 1 RepliesI have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

However, now when I open it in design view and add a new tableadapter I now cannot reference the new objects from the code. Likewise if I delete one of the existing tables in the dataset, it still appears to be there from the code (ie in intellisense)Similarly, when I examine the .xsd file, the changes I've made i the designer appear, but the changes are NOT happening in the dataset.designer.vb file. It's as if the two files are somehow out of sync

I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always.
I used the following code:
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
Public Property GradientBegin() As Color = Color.Red
But the problem I am facing is that -> on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually.

Created MyLitsBox project as described in Michael Halvorson's book MS VB 2010 Step by Step book. Tip box on p. 89 says to make programs more robust embed images into application rather than use absolute path names to link images into the application. Searched on Halvorson's recommendation "How to: Create Embedded Resources" and found the info at: [URL]
OK. As usual the most difficult thing is finding the menu item, etc., the instructions direct you to. Do the people who write these instructions ever try using them?
xxxxxxxxxxxxxxx
Instructions are as follows
To edit a resource by using the default editor
With a project selected in Solution Explorer, on the Project menu, click Properties.
Click the Resources tab.
On the Resource Designer toolbar, point to the resource view drop-down, click the arrow, and select the type of resource that you want to edit.
Double-click the resource to open the default editor for that resource type.
In the Properties window, select the Persistence property and change it to Embedded in .resx.
I guess I must accept the fact that it takes time to understand the programming environment. Information is available, but mostly fragmented. The solutions seem simple and obvious, once one has succeeded in finding them, but the way get an understanding of their simplicity can be hard.I am now working since weeks on a control class and I don't seem to get it right. When the code executes in RunTime, it executes correctly, but when I open the designer, the control location is changed to Point(0, 0).

View 1 RepliesI am creating a UserControl with rich design-time support that should eventually look like the Options window in Visual Studio (or many other applications). Basically a split container, to the left is a TreeView with 'option categories', and each node in the treeview corresponds to a 'panel' to the right with certain options.
Just for terminology, the nodes in the TreeView are OptionsNode objects, the panels (containing the controls that determine the options) are OptionsPanel controls. My UserControl itself is called OptionsView and is the control that contains the treeview as well as a panel that contains the OptionsPanels.
I have some experience in design-time coding, and I have gotten pretty far. The OptionsView control contains a property Panels that returns the ControlCollection of the right side of the split container. The user can add/remove OptionsPanels via this property (and automatically an OptionsNode is created). The property uses a custom CollectionEditor that tells the designer to create instances of type OptionsPanel (instead of just Control which is the usual collection type of ControlCollection). Furthermore, in the CreateInstance method I use the DesignerHost object and its CreateComponent method to create the panels, instead of just creating New OptionsPanel objects. This way the OptionsPanel created is selectable and editable (via property grid) during design-time:
vb.net
Protected Overrides Function CreateInstance(ByVal itemType As System.Type) As Object
If itemType Is GetType(OptionsPanel) Then

I've started a project in Expression Blend and has been working the codes in Visual Studio 2008. It was alright, no problem. I've worked heaps of projects like that before without any problems. However, out of nowhere, my WPF designer in VS2008 now gives me the following error:
Object reference not set to an instance of an object.
at MS.Internal.Package.VSIsolationProviderService.CreateIsolationProvider(String identity, AssemblyReferenceProvider assemblyReferences, IEnumerable'1 assemblyFolders)
at MS.Internal.Providers.VSDesignerContext.GetIsolationProvider(IServiceProvider provider, [Code] .....
It displays the above instead of displaying the WPF designer. Also, I cannot Debug>Start Debugging the application anymore. I can still run/test/build it in Expression studio though. The funny thing is that if I restart a project in Expression blend, copy all the xaml codes, and copy all the vb .net codes from the original application, it works for some time, and then afterwards start giving me the same error at wpf designer in VS2008.
I would like to know where the dataset designer is obtained for a vb.net 2008 appliocation I need to work on. Is this part of the initial install for visual studio.net 2008.
