vb.net message pump help
 

hi,

im trying to make a kdvd batch encoder in vb.net, everything works great but i got a slight niggle im hopin u can help me with


im using shell cmds with wait=true to go thorugh the various steps

vdub (audio extraction)
besweet (audio)
quenc(vid)
pulldown (if needed)
bbmpeg (muxing)

the main thing is id like to include a log file tab but on shell executing the form just whites out and is not responsive , after many searches on google i think it has something to do with message pump , but cant for life of me find any code on it.

im a noob @ programming and everything so far ive found by google search but cant figure this one.

can someone offer some insight as to where im going wrong please

Hi powie,

You're going to have to find out a way to redirect "stdout" of your program to a pipe, where you can capture the log.
The reason is that while your external program is executing, you loose control until it returns.
So if the running program can write to a pipe, then you can capture it on the upper forking (main calling) program.
Hope you understand what I mean.
Can't give you any more help, because I don't do any .Net programming.

after a little googling stdout does seem the way i need to go

guess i got a lot of learning to do

thanks for the nudge in the right direction :)
