I used the script provided by Matt (2008-10-02). The only thing I had trouble with was that it wouldn't delete the search.log file. I expect because I had to cd to another location to start my program. I cd'd back to where the BAT file and search.log are, but it still wouldn't delete. So I resolved that by deleting the search.log file first instead of last.

del search.log

tasklist /FI "IMAGENAME eq myprog.exe" /FO CSV > search.log

FOR /F %%A IN (search.log) DO IF %%-zA EQU 0 GOTO end

cd "C:\Program Files\MyLoc\bin"

myprog.exe myuser mypwd

:end
