I've inherited an embedded application for a scanner, it was written using visual studio 2005, C#. We now have to replace the hardware because we can't get the old ones anymore. Unfortunately, the replacement device runs on embedded compact 7.0. I've rebuilt the application and installed it on the new device. It runs but we do get some strange behaviour. Is embedded compact 7 fully compatible with ce 5? How would I go about upgrading it to ec 7. Any help appreciated.

  • Can specify "strange behaviour"? In general the app should work without issues. But this depends on the code. – josef Apr 19 '16 at 17:45
  • I think I might've found the issue, it wasn't deploying correctly and was missing a dll. – user2669338 Apr 19 '16 at 20:17
  • That results normally not in strange behaviour but an exception. – josef Apr 20 '16 at 05:14
  • No, there was no exception being thrown. The offending method call is to a third party dll which seems to execute as normal. But once we were able to debug it, we saw a message in the output window saying method not found. – user2669338 Apr 20 '16 at 08:57

I've asked this question because we had issues migrating our application from WindowsCE 5 to Windows Embedded Compact 7:

If you are using Forms, on WindowsCE 5 the constructor will always complete before OnActivated would be called, while on Embedded Compact 7, when you adjust certain Form properties, OnActivated would be called before the constructor would finish. This also applies to OnGotFocus and perhaps OnLoad, and their events (ie. form1_Activated).

Now no one has confirmed nor denied this behavior on their devices, so I'm not completely sure if this is a vendor-specific problem. You can run the code in the question to determine whether this also happens on your device.

Aside from that (and a larger screen, so we had to redesign the user interface :P) we've not had any issues migrating.
