running command line progs in a controlled manner

[kevin bailey]

hi,

i am swamped by all the documentation and i can't find something relatively
simple.

a company has an intranet and they want a browser based application to
control data import/export. i need an apsx page to run dts packages on a
separate server.

after asking here and further investigation i am going to try this using
dtsrun.exe

which brings me to my question...

i can create a system.diagnostics.process object and run the program - but
how would i capture errors from this running.

the code i found is for VB and not ASP.NET and is at he end of this message.
when i tried to run it get Catch e As Win32Exception code produces Catch e
As Win32Exception.

where is a good place for ASP.NET examples?

thanks - kev

it depends on the program you run how you detect error. when you run a
program, you have access to its stdout, and stderr streams, and its
exitcode. some programs will return a special exitcode if they failed, some
don't. some will write errors to stderr, some stdout. dtsrun.exe is better
behaved than most.
