Problem: PInvoke EVC++4.0 dll from c#.net (with sample code)

Question

I have downloaded the following demo application from code project, but I keep getting "MissingMethodException" when running it.. I have tried debugging it for 2 days but still no good news.. I have used the emulator under VS.net 2003 to run this app...would there be any prob if i don use the actual device? I dint do any 'copy-and-paste' job on the dll to the emulator... assuming that the deploying task would do the job for me site for the sample demo, with step-by-step methods: http://www.codeproject.com/netcf/MakeDemo.asp thanks for brainstorming!!
