• Automatic incremental SQL Script generation for incremental, nightly builds when using Team Build in

  - by Steve Johnson

  hi all, hope that everybody here is OK. We are using VS 2008 as development tool, TFS 2008 as version control as well as build automation. Some of our developer use dbpro for databases changes and some use SQL Server management studio. I am trying to automate build for Web Application built using C# and VB.Net. Our scenario is such that we have a central database to which our web application connects. Whenever we supply our clients with a new functionality or a bug fix, we supply them incremental builds. The SQL script is checked into source control for every incremental build when they have made and tested there changes on our central DB Server. I want to generate Differential script that can be run at the client as an incremental update script. Now to come about it is a problem. Sometimes our developers tend to forget the database change-sets and the script in the source control is missing an SP or a two. Also, sometimes we need to insert default data into some of the tables that have strict stringent values and not test values. Like a table that contains Services provided by the panel, we add a new service name, signature, credentials and service address, etc etc in the ServiceTable. Besides this many other tables may have test data that may not be needed. If we use DataCompare, it will generate changeset for required data (important for client to enable certain services) and our test data that was added to the database as a result of our testing of the functionality or bug fix. Currently i am using SQLSchemaCompareTask (from Visual Studio 2008 Team Database Professional Power Tools API) in the TFSBuild.proj file of the build definition for TFS 2008. Using SQLSchemaCompareTask, the script generated contains database names like [dbo]. etc which are not desired as the script fails when run against SQL Server 2000 databses (Some of our client still use SQL Server 2000) databases as teh backend of the application. Also default data can't be generated by this process. To overcome this problem, i have to come up with a solution that can compare databases and generate script automatically that does not have to be manually reviewed again before being sent to the client. Please suggest effective methodology of such SQL script generation and suggest whether two different databases may be used or something ? Is there any toolkit or api that can enable build automation for SQL Server databases? Thank you all. Regards Steve

• WPF ComboBox SelectedValue not updating from binding source.

  - by vg1890

  Here's my binding source object: Public Class MyListObject Private _mylist As New ObservableCollection(Of String) Private _selectedName As String Public Sub New(ByVal nameList As List(Of String), ByVal defaultName As String) For Each name In nameList _mylist.Add(name) Next _selectedName = defaultName End Sub Public ReadOnly Property MyList() As ObservableCollection(Of String) Get Return _mylist End Get End Property Public ReadOnly Property SelectedName() As String Get Return _selectedName End Get End Property End Class Here is my XAML: <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" xmlns:local="clr-namespace:WpfApplication1" > <Window.Resources> <ObjectDataProvider x:Key="MyListObject" ObjectInstance="" /> </Window.Resources> <Grid> <ComboBox Height="23" Margin="24,91,53,0" Name="ComboBox1" VerticalAlignment="Top" SelectedValue="{Binding Path=SelectedName, Source={StaticResource MyListObject}, Mode=OneWay}" ItemsSource="{Binding Path=MyList, Source={StaticResource MyListObject}, Mode=OneWay}" /> <Button Height="23" HorizontalAlignment="Left" Margin="47,0,0,87" Name="btn_List1" VerticalAlignment="Bottom" Width="75">List 1</Button> <Button Height="23" Margin="0,0,75,87" Name="btn_List2" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="75">List 2</Button> </Grid> </Window> Here's the code-behind: Class Window1 Private obj1 As MyListObject Private obj2 As MyListObject Private odp As ObjectDataProvider Public Sub New() InitializeComponent() Dim namelist1 As New List(Of String) namelist1.Add("Joe") namelist1.Add("Steve") obj1 = New MyListObject(namelist1, "Steve") . Dim namelist2 As New List(Of String) namelist2.Add("Bob") namelist2.Add("Tim") obj2 = New MyListObject(namelist2, "Tim") odp = DirectCast(Me.FindResource("MyListObject"), ObjectDataProvider) odp.ObjectInstance = obj1 End Sub Private Sub btn_List1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles btn_List1.Click odp.ObjectInstance = obj1 End Sub Private Sub btn_List2_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles btn_List2.Click odp.ObjectInstance = obj2 End Sub End Class When the Window first loads, the bindings hook up fine. The ComboBox contains the names "Joe" and "Steve" and "Steve" is selected by default. However, when I click a button to switch the ObjectInstance to obj2, the ComboBox ItemsSource gets populated correctly in the dropdown, but the SelectedValue is set to Nothing instead of being equal to obj2.SelectedName. Thanks in advance!

• DataRelation Insert and ForeignKey

  - by Steve

  Guys, I have a winforms application with two DataGridViews displaying a master-detail relationship from my Person and Address tables. Person table has a PersonID field that is auto-incrementing primary key. Address has a PersonID field that is the FK. I fill my DataTables with DataAdapter and set Person.PersonID column's AutoIncrement=true and AutoIncrementStep=-1. I can insert records in the Person DataTable from the DataGridView. The PersonID column displays unique negative values for PersonID. I update the database by calling DataAdapter.Update(PersonTable) and the negative PersonIDs are converted to positive unique values automatically by SQL Server. Here's the rub. The Address DataGridView show the address table which has a DataRelation to Person by PersonID. Inserted Person records have the temporary negative PersonID. I can now insert records into Address via DataGridView and Address.PersonID is set to the negative value from the DataRelation mapping. I call Adapter.Update(AddressTable) and the negative PersonIDs go into the Address table breaking the relationship. How do you guys handle primary/foreign keys using DataTables and master-detail DataGridViews? Thanks! Steve EDIT: After more googling, I found that SqlDataAdapter.RowUpdated event gives me what I need. I create a new command to query the last id inserted by using @@IDENTITY. It works pretty well. The DataRelation updates the Address.PersonID field for me so it's required to Update the Person table first then update the Address table. All the new records insert properly with correct ids in place! Adapter = new SqlDataAdapter(cmd); Adapter.RowUpdated += (s, e) => { if (e.StatementType != StatementType.Insert) return; //set the id for the inserted record SqlCommand c = e.Command.Connection.CreateCommand(); c.CommandText = "select @@IDENTITY id"; e.Row[0] = Convert.ToInt32( c.ExecuteScalar() ); }; Adapter.Fill(this); SqlCommandBuilder sb = new SqlCommandBuilder(Adapter); sb.GetDeleteCommand(); sb.GetUpdateCommand(); sb.GetInsertCommand(); this.Columns[0].AutoIncrement = true; this.Columns[0].AutoIncrementSeed = -1; this.Columns[0].AutoIncrementStep = -1;

• Trying to write a loop that uses an OutputStream to write to a text file.

  - by Steve McLain

  I'm not a java programmer, I'm a VB programmer. I am doing this as part of an assignment, however, I'm not asking for help on something assignment related. I'd like to figure out how to get the OutputStreamWriter to work properly in this instance. I just want to capture the values I'm generating and place them into a text document. The file is generated, but only one entry exists, not the 40 I'm expecting. I could do this in a heartbeat with VB, but java feels very strange to me right now. Your help is appreciated. Thanks, Steve Here's the code: public static void main(String[] args){ long start, end; double result,difference; try {//OutputStream code assistance from http://tutorials.jenkov.com/java-io/outputstreamwriter.html OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt"); Writer out = new OutputStreamWriter(outputStream); for(int n=1; n<=20; n++){ //Calculate the Time for n^2. start = System.nanoTime(); //Add code to call method to calculate n^2 result = mN2(n); end = System.nanoTime(); difference = (end - start); //Output results to a file out.write("N^2 End time: " + end + " Difference: " + difference + "\n"); out.close(); } } catch (IOException e){ } try { OutputStream outputStream = new FileOutputStream("c:\\Temp\\output1.txt"); Writer out = new OutputStreamWriter(outputStream); for(int n=1; n<=20; n++){ //Calculate the Time for 2^n. start = System.nanoTime(); //Add code to call method to calculate 2^n result = m2N(n); end = System.nanoTime(); difference = (end - start); //Output results to a file out.write("N^2 End time: " + end + " Difference: " + difference + "\n"); out.close(); } } catch (IOException e){ } } //Calculate N^2 public static double mN2(double n) { n = n*n; return n; } //Calculate 2N public static double m2N (double n) { n = 2*n; return n; }

  I am about to leap of a building. I have created an app for a client and all the files are in a folder on their D drive. Now it is time to go production, so I copied all my files and folders to their excisting classic asp folder on the same drive. BUT NOTHING WORKS.

• Makefile issue with compiling a C++ program

  - by Steve

  I recently got MySQL compiled and working on Cygwin, and got a simple test example from online to verify that it worked. The test example compiled and ran successfully. However, when incorporating MySQL in a hobby project of mine it isn't compiling which I believe is due to how the Makefile is setup, I have no experience with Makefiles and after reading tutorials about them, I have a better grasp but still can't get it working correctly. When I try and compile my hobby project I recieve errors such as: Obj/Database.o:Database.cpp:(.text+0x492): undefined reference to `_mysql_insert_id' Obj/Database.o:Database.cpp:(.text+0x4c1): undefined reference to `_mysql_affected_rows' collect2: ld returned 1 exit status make[1]: *** [build] Error 1 make: *** [all] Error 2 Here is my Makefile, it worked with compiling and building the source before I attempted to put in MySQL support into the project.

• Dependency Injection with Spring/Junit/JPA

  I'm trying to create JUnit tests for my JPA DAO classes, using Spring 2.5.6 and JUnit 4.8.1.

attempting to store an EntityManager object into an EntityManagerFactory field, but I don't understand how or why. My DAO classes accept both an EntityManager and EntityManagerFactory via the @PersistenceContext attribute, and they work find if I load them up and run them without the @ContextConfiguration attribute (i.e. if I just use the XmlApplcationContext to load the DAO and the EntityManagerFactory directly in setUp ()). Any insights would be appreciated. Thanks. --Steve

• Silverlight/Web Service Serializing Interface for use Client Side

  - by Steve Brouillard

  I have a Silverlight solution that references a third-party web service. This web service generates XML, which is then processed into objects for use in Silverlight binding. At one point we the processing of XML to objects was done client-side, but we ran into performance issues and decided to move this processing to the proxies in the hosting web project to improve performance (which it did). This is obviously a gross over-simplification, but should work. My basic project structure looks like this. Solution Solution.Web - Holds the web page that hosts Silverlight as well as proxies that access web services and processes as required and obviously the references to those web services). Solution.Infrastructure - Holds references to the proxy web services in the .Web project, all genned code from serialized objects from those proxies and code around those objects that need to be client-side. Solution.Book - The particular project that uses the objects in question after processed down into Infrastructure. I've defined the following Interface and Class in the Web project. They represent the type of objects that the XML from the original third-party gets transformed into and since this is the only project in the Silverlight app that is actually server-side, that was the place to define and use them. //Doesn't get much simpler than this. public interface INavigable { string Description { get; set; } } //Very simple class too public class IndexEntry : INavigable { public List<IndexCM> CMItems { get; set; } public string CPTCode { get; set; } public string DefinitionOfAbbreviations { get; set; } public string Description { get; set; } public string EtiologyCode { get; set; } public bool HighScore { get; set; } public IndexToTabularCommandArguments IndexToTabularCommandArgument { get; set; } public bool IsExpanded { get; set; } public string ManifestationCode { get; set; } public string MorphologyCode { get; set; } public List<TextItem> NonEssentialModifiersAndQualifyingText { get; set; } public string OtherItalics { get; set; } public IndexEntry Parent { get; set; } public int Score { get; set; } public string SeeAlsoReference { get; set; } public string SeeReference { get; set; } public List<IndexEntry> SubEntries { get; set; } public int Words { get; set; } } Again; both of these items are defined in the Web project. Notice that IndexEntry implments INavigable. When the code for IndexEntry is auto-genned in the Infrastructure project, the definition of the class does not include the implmentation of INavigable. After discovering this, I thought "no problem, I'll create another partial class file reiterating the implmentation". Unfortunately (I'm guessing because it isn't being serialized), that interface isn't recognized in the Infrastructure project, so I can't simply do that. Here's where it gets really weird. The BOOK project CAN see the INavigable interface. In fact I use it in Book, though Book has no reference to the Web Service in the Web project where the thing is define, though Infrastructure does. Just as a test, I linked to the INavigable source file from indside the Infrastructure project. That allowed me to reference it in that project and compile, but causes havoc in the Book project, because now there's a conflick between the one define in Infrastructure and the one defined in the Web project's web service. This is behavior I would expect. So, to try and sum up a bit. Web project has a web service that process data from a third-party service and has a class and interface defined in it. The class implements the interface. The Infrastructure project references the web service in the Web Project and the Book project references the Infrastructure project. The implmentation of the interface in the class does NOT serialize down, so the auto-genned code in INfrastructure does not show this relationship, breaking code further down-stream. The Book project, whihc is further down-stream CAN see the interface as defined in the Web Project, even though its only reference is through the Infrastructure project; whihc CAN'T see it. Am I simple missing something easy here? Can I apply an attribute to either the Interface definition or to the its implmentation in the class to ensure its visibility downstream? Anything else I can do here? I know this is a bit convoluted and anyone still with me here, thanks for your patience and any advice you might have. Cheers, Steve

• MVC Partial View to Call Display Pop-up window using jquery

  - by Gavin campbell

  Hi I have a index page the renders objects from my database as a treeview, each item has a link href="/MessageGroupType/Edit/1002 that makes an Ajax call to display a partial view in a DIV. Within the partial view there is a delete button which calls my controller to delete the item. However, i do a check to make sure the item can be deleted, if the item cant be deleted then i wish a pop-up to appear back on the edit form telling the user they cant delete this record. In my Edit partial view i have the following code " type="text/javascript" $(function() { $("#dialog").dialog(); }); <% if (Boolean.Parse(ViewData["DisplayWindow"].ToString())){% This Mesage group Type Cannot be deleted as is linked to other message group Types <% }% So my main questions are Can i make a reference to a javascript script within my Partial View (i dont want my master page to be called on the partial view) When i dynamically load the partial view data into my DIV - can i then after calling my controller insert another DIV into the first DIV. I am i doing this the wrong way - so any pointers is appreciated Cheers

• How do I correctly Re-render a Recaptcha in ASP.NET MVC 2 after an AJAX POST

  - by Eoin Campbell

  Ok... I've downloaded and implemented this Recaptcha implementation for MVC which uses the ModelState to confirm the validity of the captcha control. It works brilliantly... except when I start to use it in an AJAX Form. In a nutshell, when a div is re-rendered with AJAX, the ReCaptcha that it should contain does not appear, even though the relevant <scripts> are in the source after the partial render. Code Below. using (Ajax.BeginForm("CreateComment", "Blog", new AjaxOptions() { HttpMethod = "POST", UpdateTargetId = "CommentAdd", OnComplete="ReloadRecaptcha", OnSuccess = "ShowComment", OnFailure = "ShowComment", OnBegin = "HideComment" })) {%> <fieldset class="comment"> <legend>Add New Comment</legend> <%= Html.ValidationSummary()%> <table class="postdetails"> <tbody> <tr> <td rowspan="3" id="blahCaptcha"> <%= Html.CreateRecaptcha("recaptcha", "blackglass") %> </td> .... Remainder of Form Omitted for Brevity I've confirmed the Form is perfectly functional when the Recaptcha Control is not present and the Javascript calls in the AjaxOptions are all working fine. The problem is that if the ModelState is Invalid as a result of the Recaptcha or some other validation, then the ActionResult returns the View to reshow the form. [RecaptchaFilter(IgnoreOnMobile = true)] [HttpPost] public ActionResult CreateComment(Comment c) { if (ModelState.IsValid) { try { //Code to insert Comment To DB return Content("Thank You"); } catch { ModelState.AddRuleViolations(c.GetRuleViolations()); } } else { ModelState.AddRuleViolations(c.GetRuleViolations()); } return View("CreateComment", c); } When it's InValid and the form posts back, for some reason the ReCaptcha Control does not re-render. I've checked the source and the <script> & <noscript> blocks are present in the HTML so the HTML Helper function below is obviously working <%= Html.CreateRecaptcha("recaptcha", "blackglass") %> I assume this has something to do with scripts injected into the DOM by AJAX are not re-executed. As you can see from the HTML snippet above, I've tried to add an OnComplete= javascript function to re-create the Captcha on the client side, but although the script executes with no errors, it doesn't work. OnComplete Function is. function ReloadRecaptcha() { Recaptcha.create("my-pub-key", 'blahCaptcha', { //blahCaptcha is the ID of the <td> where the ReCaptcha should go. theme: 'blackglass' }); } Can anyone shed any light on this ? Thanks, Eoin C

• VS2010 MSTest CruiseControl.NET .NET 3.5

  - by Bill Campbell

  Hi, We're in the process of upgrading from VS2008 to VS2010 since it's now released. We are using CC.NET along with MSTest and want to use MS coverage tool instead of NCover. Interestingly, as I've seen others talking about as well, when you upgrade your project from VS2008 to VS2010 your Test Projects get converted to .NET 4. Nice move!! So WTF does one do with their CI environment in order to build this stuff (some projects in .net 3.5, some in .net 4 - these are different FRAMEWORKS!) LOL!!! It seems that I might need to have my CC.NET build two separate projects? - not sure about how to run the units tests from cruise with .net 4. Has anyone done this and have a snippet of their config they might share? And I thought this was going to be a simple thing. :( thanks! Bill44077

• MySQL Interview Questions

  - by Campbell

  Hi, I've been asked to screen some candidates for a MySQL DBA / Developer position for a role that requires an enterprise level skill set. I myself am a SQL Server person so I know what I would be looking for from that point of view with regards to scalability / design etc but is there anything specific I should be asking with regards to MySQL? I would ideally like to ask them about enterprise level features of MySQL that they would typically only use when working on a big database. Need to separate out the enterprise developers from the home / small website kind of guys. Thanks.

• RhinoMocks AAA Syntax

  - by Bill Campbell

  Hi, I've spent a good part of the day trying to figure out why a simple RhinoMocks test doesn't return the value I'm setting in the return. I'm sure that I'm just missing something really simple but I can't figure it out. Here's my test: [TestMethod] public void CopyvRAFiles_ShouldCallCopyvRAFiles_ShouldReturnTrue2() { FileInfo fi = new FileInfo(@"c:\Myprogram.txt"); FileInfo[] myFileInfo = new FileInfo[2]; myFileInfo[0] = fi; myFileInfo[1] = fi; var mockSystemIO = MockRepository.GenerateMock<ISystemIO>(); mockSystemIO.Stub(x => x.GetFilesForCopy("c:")).Return(myFileInfo); mockSystemIO.Expect(y => y.FileCopyDateCheck(@"c:\Myprogram.txt", @"c:\Myprogram.txt")).Return("Test"); CopyFiles copy = new CopyFiles(mockSystemIO); List<string> retValue = copy.CopyvRAFiles("c:", "c:", new AdminWindowViewModel(vRASharedData)); mockSystemIO.VerifyAllExpectations(); } I have an interface for my SystemIO class I'm passing in a mock for that to my CopyFiles class. I'm setting an expectation on my FileCopyDatCheck method and saying that it should Return("Test"). When I step through the code, it returns a null insteaed. Any ideas what I'm missing here? Here's my CopyFiles class Method: public List<string> CopyvRAFiles(string currentDirectoryPath, string destPath, AdminWindowViewModel adminWindowViewModel) { string fileCopied; List<string> filesCopied = new List<string>(); try { sysIO.CreateDirectoryIfNotExist(destPath); FileInfo[] files = sysIO.GetFilesForCopy(currentDirectoryPath); if (files != null) { foreach (FileInfo file in files) { fileCopied = sysIO.FileCopyDateCheck(file.FullName, destPath + file.Name); filesCopied.Add(fileCopied); } } //adminWindowViewModel.CheckFilesThatRequireSystemUpdate(filesCopied); return filesCopied; } catch (Exception ex) { ExceptionPolicy.HandleException(ex, "vRAClientPolicy"); Console.WriteLine("{0} Exception caught.", ex); ShowErrorMessageDialog(ex); return null; } } I would think that "fileCopied" would have the Return value set by the Expect. The GetFilesForCopy returns the two files in myFileInfo. Please Help. :) thanks in advance!

• How to tell if Microsoft Works is 32 or 64 bit? Please Help!

  - by Bill Campbell

  Hi, I am trying to convert one of our apps to run on Win7 64 bit from XP 32 bit. One of the things that it uses is Excel to import files. It's a little complicated since it was using Microsoft.Jet.OLEDB.4.0 (Excel). I found Office 14 (2010) has a 64bit version I can download. I downloaded Office 2010 Beta but it didn't seem to install Microsoft.ACE.OLEDB.14.0. I found that I could download 2010 Office System Driver Beta: Data Connectivity Components which has the ACE.OLEDB.14 in it but when I try to install it, the installed tells me "You cannot install the 64-bit version of Access Database engine for Microsoft Office 2010 because you currently have 32-bit Office products installed". How do I determine what 32bit office products this is reffering to? My Dell came with Microsoft Works installed. I don't know if this is 32 or 64 bit. Is there anyway to tell? I don't want to uninstall this if it's not the problem and I'm not sure what else might be the problem. Any help would be appreciated! thanks, Bill

• Can rpmbuild ingore files in buildroot?

  - by Noah Campbell

  I have a target directory that is checked into svn. I use the target as the --buildroot when I run rpmbuild. This causes rpmbuild to loose it mind because of the .svn directories in each directory. Is there a way to tell rpmbuild to relax? I looked at svn export target target-build, but it only knows about files tracked by rpm. Perhaps not a bad way to do it, but I'm not quite sure that is the best way.

• Is there a suggested solution structure for ASP.NET MVC Production Apps

  - by Eoin Campbell

  In general, I don't like to keep code (BaseClasses or DataAccess Code) in the App_Code directory of an ASP.NET Site. I'll usually pull this stuff out into a MySite.BusinessLogic & MySite.DataAccess DLL's respectively. I'm wondering should I be doing the same for ASP.NET MVC. Would it be better to Organise the solution something along the lines of MySite.Common - DLL - (Basic Functionality built on .NET System Dlls) MySite.DAL - DLL - (DataAccessLayer & DBML Files) MySite.Models - DLL - (MVC Models e.g. Repository Classes) MySite.Controllers - DLL (MVC Controllers which use Models) MySite - ASP.NET MVC Site. Or am I missing something... presumably, I'll lose some of the nice (Add View, Go To Controller, context menu items that have been added)

• LINQ OrderBy: best search results at top of results list

  - by p.campbell

  Consider the need to search a list of Customer by both first and last names. The desire is to have the results list sorted by the Customer with the most matches in the search terms. FirstName LastName ---------- --------- Foo Laurie Bar Jackson Jackson Bro Laurie Foo Jackson Laurie string[] searchTerms = new string[] {"Jackson", "Laurie"}; //want to find those customers with first, last or BOTH names in the searchTerms var matchingCusts = Customers .Where(m => searchTerms.Contains(m.FirstName) || searchTerms.Contains(m.LastName)) .ToList(); /* Want to sort for those results with BOTH FirstName and LastName matching in the search terms. Those that match on both First and Last should be at the top of the results, the rest who match on one property should be below. */ return matchingCusts.OrderBy(m=>m); Desired Sort: Jackson Laurie (matches on both properties) Foo Laurie Bar Jackson Jackson Bro Laurie Foo How can I achieve this desired functionality with LINQ and OrderBy / OrderByDescending?

• WPF TextBlock Binding to DependencyProperty

  - by Bill Campbell

  Hi, I have what I believe to be about one of the most simple cases of attempting to bind a view to a dependencyproperty in the view model. It seems that the initial changes are reflected in the view but other changes to the DP do not update the view's TextBlock. I'm probably just missing something simple but I just can't see what it is. Please take a look... My XAML has a status bar on the bottom of the window. I want to bind to the DP "VRAStatus". <StatusBar x:Name="sbar" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" VerticalAlignment="Bottom" Background="LightBlue" Opacity="0.4" DockPanel.Dock="Bottom" > <StatusBarItem> <TextBlock x:Name="statusBar" Text="{Binding VRAStatus}" /> </StatusBarItem> <StatusBarItem> <Separator Style="{StaticResource StatusBarSeparatorStyle}"/> </StatusBarItem> </StatusBar> My viewmodel has the DP defined: public string VRAStatus { get { return (string)GetValue(VRAStatusProperty); } set { SetValue(VRAStatusProperty, value); } } // Using a DependencyProperty as the backing store for VRAStatus. public static readonly DependencyProperty VRAStatusProperty = DependencyProperty.Register("VRAStatus", typeof(string), typeof(PenskeRouteAssistViewModel),new PropertyMetadata(string.Empty)); Then, in my code I set the DP: VRAStatus = "Test Message..."; Is there something obvious here that I am missing? In my constructor for the viewmodel I set the DP like this: VRAStatus = "Ready"; I never get the Test Message to display. Please Help. thanks in advance! Bill

• What is the suggested approach to Syncing/Backing up/Restoring from SQL Server 2008 to SQL Server 20

  - by Eoin Campbell

  I only have SQL Server 2008 (Dev Edition) on my development machine I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database) I'm just wondering what the best approach is for: Getting the initlal DB Structure & Data into production. And keeping any structural changes/data changes in sync in future. As far as I can see... Replication - not an option cos I can't connect to the production DB. Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway. Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 - 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web) Are there any other possibile solutions that I'm not considering.
