when I did P/Invoke-calls(CreateToolhelp32Snapshot function) from managed
Csharp code to unmanaged api toolhelp.dll, there is a error prompt:

---code------
[DllImport("Toolhelp")]
public static extern IntPtr CreateToolhelp32Snapshot(int flags, int
procID);

¡­¡­
¡­¡­

IntPtr h = CoreLibMem.CreateToolhelp32Snapshot(0x00000002,0);
¡­¡­

----error prompt----
unsettled¡°System.MissingMethodException¡± error returned in MemoryDll.dll.
 
I do it in the emulator.
If that is not supported, how can I get the processes list in current system
running the emulator?

You should deploy toolhelp.dll into \windows\ before run your
application. toolhelp.dll you can find in \Microsoft Visual Studio .NET
2003\CompactFrameworkSDK\WinCE Utilities\ToolHelp\WinCE4\ for Simulator
processor architecture must be x86.
