Thanks for your reply.
I see this errors for WPF Application:
Error 1 Library project file cannot specify ApplicationDefinition element.
Error 2 The project file contains a property value that is not valid.

Remove the App.xaml and App.xaml.cs files. They are, effectively, the entry point for a WPF executable and they are not needed in a class library. The build type of App.xaml is ApplicationDefinition.

Oh thanks Pete O'Hanlon, its working fine.
One thing i want to put here: if I don't remove the App.xaml and App.xaml.cs file, and Change Build Action from ApplicationDefinition to Page then also it works.
Thanks

It does, but the App.xaml makes no sense inside the class library.
|
|
|
|
|
Yes you are correct, it doesn't make sense in class library. But my requirement is sometime I need DLL and sometime EXE, so I am not removing App.xaml file.
|
|

That's just really weird, and not a requirement, it sounds like a solution to another requirement.
The 'normal' way would be move the common bits to a class library, then you have an exe that references that library.
You don't switch an exe to dll just by changing the project setup or visa versa.
|
|
|
|
|
It's not weird, if I want reference the DLL in multiple exe other than the exe which is generated from by changing project output type Windows Application.
|
|
|
|
|
If you want to reference the dll from multiple exe's(or other dll's) then that's exactly what a class library is for.
Why do you think you now need to change that same class library to an exe? what is the exe going to do?
|
|
|
|
|
This library contains XAML file, if I make exe of it then doesnt required to add reference of DLL.
|
|
|
|

Not sure I get you... but if you want a class library to contain xaml (Windows, Pages, UserControls etc) then it can do, and yes you might need to manually add some references to the default 'class library' visual studio template.
If you create a WPF app then obviously the template already contains all the basic references you need.
You still don't need to switch a single project between a class lib and an application types.

I want to add a table to a DockPanel. Please see the table demo.
The text are all hardcoded or variables in the code. All the numbers are from code, say fields.
What should I select, datagrid or grid or table.
Thanks for code snippet.

You need to use a data table, bind the ItemSource to your collection and define the DataColumns with Header and Binding
<DataGrid Grid.Row="1"
Name="dgDB"
AutoGenerateColumns="False"
CanUserAddRows="False"
ItemsSource="{Binding DatabaseList}"
SelectedItem="{Binding SelectedDatabase, Mode=TwoWay}"
Margin="15"
IsReadOnly="True"
MouseDoubleClick="GridClick">
<DataGrid.Columns>
<DataGridTextColumn Header="Database"
Width="*"
Binding="{Binding DatabaseName}" />
</DataGrid.Columns>
</DataGrid>
Instead of Row="1" you would use DockPanel

Hi, the data is not from database. Just several values, say:
IVR-Success=50;
IVR-Fail=2;
PAYMENT-Success=30;
PAYMENT-Fail=0;
CALL-Success=100;
CALL-Fail=2;
The total can be calculated. Just 3x3 table, no more rows or columns. Is it too complicated by using datagrid?

Yes, the content is not dynamic so just place the labels and textboxes where they look good and bind each one to a single property in the VM.

Hello
I have change the value in the web.config to connect my project silverlight to database but I have this problem on this line:
public Viaccess.Vite.AdministrationSL.SvcAdmin.WcfResultOfArrayOfPackageBOx8pdn48J EndGetAllPCKs(System.IAsyncResult result)
{
object[] _args = new object[0];
Viaccess.Vite.AdministrationSL.SvcAdmin.WcfResultOfArrayOfPackageBOx8pdn48J _result = ((Viaccess.Vite.AdministrationSL.SvcAdmin.WcfResultOfArrayOfPackageBOx8pdn48J)(base.EndInvoke("GetAllPCKs", _args, result)));
return _result;
}
And the message is "The remote server returned an error: NotFound".
The project use WCF.
Thanks
(Sorry I'm french and my English is not very good)

I then build the wcf and run it locally and test the connection using the Wcf Test Client and pull back the GetData.
I then change the web config and include the client access policy and cross domain xml files. Youwill need to find a couple of decent examples to work from, this is my config file

<configuration>
<configSections>
</configSections>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime maxRequestLength="40000"/>

</system.web>
<system.serviceModel>
<bindings>
<basicHttpBinding>

That part's easy - just pass the path of the file to Process.Start, and Windows will open it using the associated program.
Process.Start(@"C:\Path\To\Your\File.doc");

How would the DataTransferManager solve the issue of opening a document with the user-preferred application, rather than the current default application, if the user isn't going to configure that application in advance?

Yes, but that's the first part of your question, which I didn't attempt to answer. 
I was answering the second part:

I'm still struggling to see how any API could use the user's preferred application, rather than the system default application, if the user hasn't configured anything.
Based on your previous messages, the user wants to open a text file in Notepad++, but the file association is configured to use Notepad. Unless the user changes that configuration, how would an API know to open the file in anything other than Notepad? Short of prompting the user every time you open a file, I don't see how that could work.
No matter how good the APIs are, I don't think Microsoft has invented a mind-reading API yet.

I am working on a WPF 4.0 app that calls to the back end via an MVC 4 Web API.
I have a view called Injuries. I have an InjuryEntity which contains an ObservableCollection of DocumentEntity.
I'm using an ObservableCollection because the WPF UI is bound as such:
<DataGrid Grid.Row="1"
Grid.Column="0"
Background="White"
ItemsSource="{Binding SelectedInjury.Documents}"
SelectedItem="{Binding SelectedDocument}"
AutoGenerateColumns="False"
FontSize="12"
FontWeight="Normal"
FontStyle="Normal"
IsReadOnly="True"
TabIndex="1200"
Height="130"
Margin="3">
When I call
InjuryEntity.Documents.Add()
everything works fine. I am able to save the data to the DB with no problem.
Now, when I call back into the API to get the Injuries, I get back null. The ENTIRE Injury entity is null, not just the documents.
If I make the ObservableCollection into List<>, then the data comes back fine.
I'm using ObservableCollection because in injury entity's Documents collection makes use of the Collection_Changed event so that I can do:
Documents = new List<InjuryDocumentsEntity>();
Documents.CollectionChanged += Documents_CollectionChanged;
private void Documents_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
RaisePropertyChanged("Documents");
}
This allows the data grid and other UI elements the be refreshed as soon as a collection item changes.
So, the problem appears to be that MVC 4 doesn't like ObservableCollection.
I've been Googling, but I'm not finding much help.
Can anyone shed some light on this?
Thanks
If it's not broken, fix it until it is

It sounds like a serialization problem.
Have the API return a List<>, and map that to an ObservableCollection<> in your view model.
