  • 3. C#-App doesn't run (Win CE device, Compact Framework included)
    Hello, we have aproblem with VS .NET 2003, C#-App and our Device with a Win CE image and included Compact Framework (Platformbuilder 4.2 with all QFEs) VS .NET builds and deploys the C#-Testapp, says launching application, but nothing happens. Also manually starting of the app on the device does'nt work. How can we determine that the .NET Compact Framework is working? By testing with the Emulator we see a Compact Framework folder in the folder Program Files but on our device we doesn't see this folder. Is this a sign for the inactive Compact Framework? Thanks in advance, Michael
  • 4. SQL Server CE Administration (NTFS Permissions)
    When I attempt to specify the NTFS UNC share for the snapshot folder to the Administrator user through IIS it tells me that the network location cannot be reached. The location is there. I explicitly assigned the user permissions on the share and the folder. I also assigned permissions to the GROUP Administrators and to everyone on the group and the share. Just to be sure. It will not allow me to get through that wizard. I am a newbie to MSSQL but not to databases. I recently converted my file system from a FAT32 to an NTFS file system. I thought that would eliminate the problem. Anybody have any ideas. Thanks in advance for your help.

If you go through HKEY_LOCAL_MACHINE\Drivers\Active and look through all the 
keys in there (1 to xx) the values in there should tell what is assigned to 
which comm port.

Exactly, there's no right answer to the original question.  It might be 
*any* COM port (or it might not even be assigned a COM<x> name at all). 
Check with the CF card manufacturer...

4.Differences in PocetPC 2002 vs 2003 regarding serial ports/compact flash 

I'm writing an appliaction that is using the serial/compact flash port.
In the application that runs on PocetPC 2002 the systems works perfect,
but on 2003 the device connected to the port often don't seem to work
correctly. The same device works fine on the same application on the
PocetPC 2002 platform. It is not a problem of opening the serial port,
that works fine on both systems, but when the port is open the device
don't seem to responde to commands on the 2003 PocketPc.
Does anybody know if there has been changes made in PocktPC 2003
compared to 2002? (or even better if anybody knows how to solve the
problem)
