Hi,
I read in this link “http://support.microsoft.com/kb/555578/en-us” that the .NET Compact Framework brings the followings dll.
COREDLL.DLL
AYGShell.dll – Pocket PC shell functions
CommCtrl.dll – Common control lib
WinSock.dll – Windows Sockets
Phone.dll – High level phone control
SMS.dll – SMS messaging API
I’m working on VB 2005 whit .NET Compact Framework v2 trying to develop an application that sends SMS but in all the code examples that I could find they call an dll file named ”sms.dll”:
<System.Runtime.InteropServices.DllImport("sms.dll")>
I been searching in the internet, in all the directories of my computer looking for that file. If some body knows were I can find it please let me know.

Can’t find “sms.dll” file

This DLL lives in ROM of your Windows Mobile device.
If you are working with a Windows Mobile 5 based device you can use the Microsoft provided managed implementaion (see here: http://msdn.microsoft.com/library/default.asp url=/library/en-us/mobilesdk5/html/N_Microsoft_WindowsMobile_PocketOutlook.asp)
For earlier devices, OpenNETCF.org Smart Device Framework provides a wrapper. (See here: http://www.opennetcf.org/)
