I have Windows Mobile 5.0 Pocket PC SDK installed. Pls help me with the solution

Do you have sms.dll on the system?

I didn't find the file sms.dll in my system.Doesn't it come with windows mobile 5.0 SDK?

I'm not sure. You should probably do a bit more research to see if it exists or where it comes from.

Please do not double post your question. I have deleted it.
