VS 2005 - Redirect Input Stream To Process

I don't know VB very well, but I need to create a wrapper program for any executable that logs the arguments, all input, output and err information:

My wrapper is called: e.g. someApp.exe arg1 arg2
Logs to someApp.log: arg1 arg2
Calls original executable: _someApp.exe arg1 arg2
Must log and forward any console input to _someApp process inputstream
Must log any output and error stream from _someApp process

I'm stuck at point 4 now:
Dim p As New ProcessStartInfo
p.FileName = execute
p.Arguments = Command()
p.UseShellExecute = False
p.CreateNoWindow =
[Code] .....

After _someApp ends I am able to read out and err stream to log it, but I still need to provide my own wrappers input to the process and I want to read out and err stream as it happens.
