In flash i read the image name from dataProvider of the datagrid. and then use the “Loader” to show the image.

Upload the image:

 –>web service ( save image name) –> database
Flash { –>Asp.net page (change the image size)–> upload image to the folder

At this moment, i can use the Get function withe parameter, delete function and the update function.

2 weeks ago. I trid to use the Flash “WebServiceConnector” to connect the WebService and binding the data to the Flash datagrid component. But i found that it was only can show the data and if i wanted to call the webservice function with the parameter the Flash would has a error message.

For this problem, may be it’s was my mistake. i will try to found out the solution some time in the future.

The flash output show below:
Error opening URL ‘http://localhost:1500/Service1.asmx’

‘ _
‘Public Function GetListOfGalleries() As String
‘ Dim gallery As New Gallery
‘ Dim ds As New DataSet
‘ ‘Dim ar As Array
‘ ds = gallery.GetListOfGalleries()
‘ Dim XMLDoc As New System.Xml.XmlDataDocument(ds)
‘ Return XMLDoc.InnerXml
‘End Function

So i needed to find another solution. I only have one choice was web service export the array to the flash datagrid.
So abandon the dataset use the generic list in the web service. Luckly the solution was the Generic List format to Array. And this time the flash datagrid was worded.

The follow code is show how to change the Generic List to Array:

_
Public Function GetListOfGalleries() As Gallery()
Dim gallery As New Gallery
Dim ds As New DataSet
Dim g() As Gallery
g = gallery.GetListOfGalleries().ToArray
Return g
End Function

And i found that:
The wizard has problems with any web services returning ASP.NET DataSets; therefore, services returning a .NET DataSet cannot be used with the wizard. Likewise, a web service won’t be able to function with the Data Connection wizard if it only returns a numeric or simple string value.

The Data Connection wizard (and the DataGrid component itself, for that matter) is really only designed to work with a series of similar items, such as an array. Before using the Data Connection wizard, you need to be aware of the following conditions:

The wizard doesn’t work in every situation. The target XML or web service must return an array for the wizard to work effectively.

Reference:http://www.adobe.com/devnet/flash/articles/datawizards_06.html

Public Function GetListOfGalleries() As DataSet
Dim db As Database = DatabaseFactory.CreateDatabase(“GalleryDatabase”)
Dim dbCommand As DbCommand = db.GetStoredProcCommand(“GetGalleries”)

Dim ds As New DataSet
ds = db.ExecuteDataSet(dbCommand)
Return ds

End Function

Cannot serialize member System.ComponentModel.MarshalByValueComponent.Site of type System.ComponentModel.ISite because it is an interface.

Firstly i try to comment the: Inherits System.Web.Services.WebService.
And it was worked. And then i started the web siervice try to execute the web service and found out there were nothing message show in the XML file.

So i uncomment the “Inherits System.Web.Services.WebService”. and try to find out the reason of the this error.

I have tried to comment the GetThread and UpdataThread function only DeleteThread function left, and it was perfect word.

From the google i found:

CAUSE
This is by design. The DataTable, DataRow, DataView, and DataViewManager
objects are not serializable and cannot be returned from a Web Service. In
order to return less than a complete DataSet, you have to copy the data you
wish to return to a new DataSet.

RESOLUTION
You can resolve this issue by returning a DataSet instead of a DataTable.
DataSets can contain one or more DataTables.
