I'm fairly new to the MS Sync framework and have been beating my head against the wall for about four hours now to no avail. I'm simply trying to sync my databases (one "master" SQL Server 2008 with a SQL Server CE, the client) with:
Dim syncAgent As DataCacheSyncAgent = New DataCacheSyncAgent()
Dim syncStats As Microsoft.Synchronization.Data.SyncStatistics = syncAgent.Synchronize()
It works just fine in Visual Studio 2010 and always manages to sync, but now that I'm trying to implement it on my client's computers, I always get the error:
The specified change tracking operation is not supported. To carry out this operation on the table, disable the change tracking on the table, and enable the change tracking.

I've downloaded the MSDN "101 VB Samples" from the MS site and I'm getting an error that reads "The project type is not supported by this installation". I can open the other files that I've tried (about a dozen in other folders), so I'm wondering if it is something specific with the VSTO files, or something about my VB setup.
I thought at first it was a problem with the path where the file is sitting, but even moving it from C:Documents and Settings[my name]My DocumentsMSDN to C: didn't work...Edit: I have also tried opening in notepad and converting the file to UTF-8, changing the File Association from MS Visual Studio version selector to devenv.exe, and running devenv /setup at the command prompt, all with no luck (all these ideas were found through Googling the error message....).

I've got a piece of code in a project (MyProject) that contains early bound object from a referenced assembly (We'll call it CommonAssembly):
Dim myObject As CommonAssembly.MyEarlyBoundType
now I have another assembly that is dynamically loaded because it is not present in all projects:
Dim myLateBoundObject As Object = AppDomain.CurrentDomain.CreateInstanceAndUnwrap("Utils", "Utils.MyLateBoundType")
MyLateBoundType derives from CommonAssembly.MyEarlyBoundType, and I want to cast myObject to myLateBoundObject and then programmatically invoke the additional

I am using an ADODB connection to a Sybase ASE Database for a small app that runs queries and returns the results to a grid, to XML and to Schema file. I recently tried the query on a Sybase script (Between a Begin and End statement) and had an exception when I used RS.EOF which reported "Operation is not allowed when the object is closed." The code works fine for other queries, including those between begin and end statements, so I did some debugging and found that the failure only happens when my SQL script (Which is typed into a rich text box) contains either Sybase variables (ex. @MyTable) or uses temp tables (ex. Select * into #mytemptable from myrealtable). The actual execution works OK (without an exception) but the recordset seems to be closed. A failing example is :
Begin
Declare @Name Varchar(30)
Select @Name = "MY_TABLE"

Essentially every time I run my form it tells me that the operation is not allowed when the object is closed and it points towards my recordset. Below is my code in full (given to me by a teacher! not my own) and I wondered if you could tell me what the problem is. As I understand it there is another option to ADODB which is more appropriate for .net.
Code:
Option Compare Text
Public Class Form1
Private m_cnADOConnection As New ADODB.Connection

Error Message: "This server version is not supported. Only servers up to Microsoft SQL 2005 are supported VB.NET" I am using VB.NET 2008 and attempting to connect to SQL Server 2008 with XP as the operating system.

FYI, the error does not occur when I am using code to connect to SQL Server but when I attempt to connect using one of the designer wizards this error occure.
