Getting the return code from a shelled DOS program

I am executing a DOS program from my VB app (as an alternative to Shell, I am using various API processes that I found on this forum to make it run synchronously). That part is fine. What I haven't yet been able to find is the necessary to code to read a return code back from this program (for example, if I was running a DOS BAT file, I could test this return code with ErrorLevel). Can I do the equivalent of test for errorlevel in my VB app? TIA

you should be able to shell out using the waitforsingleobjectapi. On return if it succeeded then the return code will be 0 if it failed then the return code will be somthing else.
