SqlCeConnection Failing To Open A Connection To The SQL Server 2005 Mobile Edition

Good day,

I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database.
The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.

Here is the code I am using:




Code Snippet
Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"




Code Snippet

Imports System.Data.SqlServerCe

Public Class DBManager

Public Shared gSQLCEConnection As SqlCeConnection


Public Shared Function OpenDB() As Boolean

If gSQLCEConnection IsNot Nothing Then

Throw New InvalidOperationException("Connection already open.")
End If
gSQLCEConnection = New SqlCeConnection(gConnectionString)
Try

gSQLCEConnection.Open() 'Error occurs here
Return True
Catch ex As SqlCeException

MsgBox(ex.Message & vbCrLf & ex.HResult & vbCrLf & ex.NativeError & vbCrLf & ex.Source)
Return False
End Try
End Function


In the immediate window I recieve the following messages:


A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll


I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.

Here is the exception output:

Message: "" (Blank)
HResult: -2147024882
NativeError: 0
Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider

Programs under Remove Programs on the PDA are:
Microsoft .NET CF 2.0 ENU-String R...
Microsoft .NET Compact Framework...
Microsoft SQL Client
Microsoft SQL Mobile 2005
Microsoft SQL Mobile 2005 [EN]
Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQL Server 2005 Compact...
Microsoft SQLCE 2.0
Microsoft SQLCE 2.0 Dev

Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid.
The call to OpenDB occurs in the form_load of the startup object.

Thanks in advance,

Leon
