Hi!

When I install my program, I install .net compact 1.0 SP3, SQLCE 2.0
and my program, so I install 3 cabs.

I have run my program on WM6.0 it's ok, but on WM6.1 my program dont'
run and when I remove CF compact 1.0 my program runs, but I want that
my program run with dll from CF 1.0 and not CF 2.0.

Can I do that ?

The basic answer is no. And you shouldn't be trying to install .NET CF 1.0
over the top of 2.0, which I think is what comes in ROM with WM6.1. You can
tell the run-time to run your EXE as though it was 1.0, but I'm unclear on
why you'd want to do that. Give us a justification before we dive into
describing how to do this...

Il se trouve que Paul G. Tobey [eMVP] a formulￜ :

Because I've developped an application since 2003. And I have no
problems on several device(WM2003, WM5.0, WM6.0), but with a WM6.1
device I have a problem when calling ReadFile API for communicate with
Serial Port(see message ID 121225 on this forum). And I have read on
forums that there is a bug with ReadFile on CF2.0

So I want to force my progam to runs with CF1.0

Hi,

There is is problem with reads. This has to be solve by changing the
threading approach. You cannot poll the ReadFile API in a loop, you have to
use the WaitCommEvent API callback instead (and call ReadFile only after a
WaitCommEvent is generated by the API). I think this change is needed for
any Windows Mobile device later than WM5.0 SP1. I show the source code for
this approach, in VB, in my book.

However, I think the appropriate way to handle this porting problem is to
use the SerialPort object that is built into the Compact Framework 2.0 or
later (System.IO.Ports.SerialPort).
