Hi all!

I'm trying to migrate a Pocket PC application from .NET CF 1 to .NET CF 2.

But I get 2 errors:

1. All System.Data.SqlClient.* objects get underlined, and when I look at
the error, I see:

Reference required to assembly 'System, Version=1.0.5000.0, Culture=neutral,
PublicKeyToken=969db8053d3322ac' containing the base class
'System.ComponentModel.Component'. Add one to your project.

The Problem is, that this base class, is not present on my computer, where I
installed the .NET CF 2 SDK.

Does anyone know this problem?

2. When I use message-boxes, I configure the properties like: ",
MsgBoxStyle.Information + MsgBoxStyle.OKOnly,". But since CF 2 I get an
error saying: "Implicit conversion from 'Integer' to
'Microsoft.VisualBasic.MsgBoxStyle'."
Did this change from CF 1 to CF 2?

I hope, someone can help :)

Thanks & Greetz

This was always this way: for binary "OR" you should use the Or keyword.

Probably in CF1 you are used to keep Option Strict Off, that *finally* is On
by default.
 
Check that you have the correct versions of the SqlClient assemblies
referenced. In v1.0 there was a System.Data.Common.dll assembly which was
used by this provider, in v2.0 this assembly has been merged into
System.Data and more closely matches the desktop. You may have an erroneous
reference to System.Data.Common which in turn references the v1.0 version of
System.dll

If this project has been upgraded from V1, please make sure all references
to CF V1 assemblies have been removed and replaced with CF V2 references.

Specifically, remove references to SQL CE 2.0 managed provider
(System.Data.SqlServerCe.dll version 1.0.5000.0) and System.Data.Common.dll.

Add reference to SQL Mobile 3.0 provider (System.Data.SqlServerCe.dll
version 3.0.3600.0).



In theory you may be able to create V2 application which would use SQL CE
2.0, but that's not officially supported and/or tested.

Running V1 applications which are using SQL CE 2.0 is supported/tested (SQL
CE 2.0 needs to be installed separately).
