Re: Why is this?....The thread '' (0xd88) has exited with code 0 (0x0).

Goto Debug options on the Visual Studio menu, choose exceptions, and check all items.
Run your code again and see if an error is now thrown by the code.

If you run any .NET application you will see this message at the end of execution.
It is a standard message indicating that the thread ended, that there was no exception, and that the return code was 0.

So you need to look at anywhere in your code where you are ending the thread or attempting to execute and instance of an object but not keeping a reference to that object.

Try putting a breakpoint in the first line of your application and see what happens when you walk through the code. If your code debugging just 'disappears' with the application ending, then the problem is the way the Sharepoint app is being loaded at the higher level.

Hi forPower,

You can check your Application_Startup event inside your App.xaml file whether you are setting your RootVisual or not. If you are not setting anything to RootVisual it might exit.

Have a look into this: App.xaml File Structure[^]

Also check whether you are exiting the application by mistake.

There are plenty of different approaches available.
Do a search on the internet to comapare these approaches - some may be better for SL2 and others for SL3 and SL4.

Have a look here to see an implementation of the PagedCollectionView.

The AgDataGrid from DevExpress has a free version and has excel like filters.

Ive been using it at work and its pretty good. I have the supported version so I'm not 100% sure if the filters come with the free version.

Problem with multiple windows in WPF

Hi its been a while since I've had a problem, but this has stumped me.

I have a start-up screen which has three button on it and one of these opens another WPF window. I would like the window that opens to be able to be closed and re-opened if the button on the start screen is pressed again. However it seems to be crashing and the error I get is:

Cannot convert the value in attribute 'Content' to object of type 'System.Object'. Specified element is already the logical child of another element. Disconnect it first. Error at object 'System.Windows.Controls.ContentControl' in markup file 'VisualEditor;component/designer.xaml' Line 28 Position 46.

Any help is much appreciated.

Hy,

Since you haven't shown any code or Xaml that you have, based on the error message, I would say/guess
that your designer.xaml markup holds a reference to the sencond window(or a CONTROL in it) that you are trying to open/close.
this really silly code inside window1/mainwindow works just fine:

private Window2 w2 =null;

private void button1_Click(object sender, RoutedEventArgs e)
{
    if (w2 == null)
    {
        w2 = new Window2();
        w2.Show();
    }
    else
    {
        w2.Close();
        w2 = null;
    }
    e.Handled=true;
}

Cheers for your reply.

It didn't seem to work still but I have had an epiphany and manage to solve it thanks again for the help. It was because the content of some of my items on my second form was using static resource so on close of the second window I set the content to null.

VS2010 - Crystal Report WPF Application

Windows forms and Asp.net have not changed but the WPF version doesn't include the traditional way of viewing the report i.e. the report viewer doesnt include a direct report source. Did anyone figure out the new way of doing it (I am not interested in the examples of winform interop)as Google didnt yield much results?

Before defining the report source you should add a viewercore.

Example

reportViewer.ViewerCore.ReportSource = CrystalReport1

Silverlight and WCF issue

CrazyCoder2622-Apr-10 22:35

22-Apr-10 22:35

Hi, I have developed an application using Silverlight3 and WCF where I am fetching some data from database and binding to a datagrid.For small resultsets the application is working fine.But for large resultsets it gives an error at EndGet Method.
I checked the buffersize,maxReceivedMessageSize,receiveTimeout,closeTimeout,
openTimeout,sendTimeout.All are set to suitable values.
Can anyone help on this issue?

maxbufferSize,maxReceiveSize is set to the maximum integer value.

Increase sendTimeout to a bigger value and try again.
