Hi Khalaf,

This is because of the project configuration.

  • Check if CMessagingClient.dll is in the correct location where the compiler of the app is looking for it.
  • Check if the correct Build has been selected in the Studio Configuration Manager
  • Use the correct CMessagingClient.dll from the SUP/SMP SDK (There's one for the Win32 Application, and one for the Windows Mobile Applications).

Hi Akos,

i did all the above but still same problem.

i am using smp 3.0 for creating windows mobile app MBO approach.




Interesting. Did you set all the needed things with the environment variables?

Is the dll placed in a location where the SDK has access to read from?

Maybe an unsupported Windows version is the one that you have?
