Capturing DOS output from VB6

Hello all,

I am shelling this line of code from VB6 to compile various .java files into classes:

"C:\jdk1.3.1_02\bin\javac -d D:\Temp\SPACE\java_classes\ -classpath D:\Temp\SPACE\java_classes\;D:\Dev\Java\com\calibre\space\mail.jar;D:\Dev\Java\com\calibre\space\servlet.jar D:\Dev\Java\com\calibre\space\*.java"

This works fine if no problems are encountered in the compile process. But fails if one of the files doesn't compile. No error messages display though to tell the user something has gone wrong. If I run the above command in a DOS window, then I get some error messages that are useful. I was hoping to be able to catch these error messages & relay them back to my VB app so that the user can see what's going on if the command should fail.

I have searched the microsoft website & found some info (http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/Q173/0/85.ASP&NoWebContent=1), but unfortunately I can't get their example to work!

If any one can offer any suggestions I would be most grateful. Thank you in advance for your help.

Michael.

Hi Ryancys,

Thanks for your reply. Unfortunately I experienced the same problem that Trowa encountered when trying to get the Microsoft example code to work for the javac command (the app hangs on the ReadFile call).... and it seems that on that thread no solution was found to this problem :(

The Microsoft has a good example for this:

Then read at tips 12

Thanks & Cheers

Thanks Fantasy, but I'm not dealing with menu items (unless I've misunderstood!). I have however since found a working example..... I've lost the URL (doh). Is it possible to attach files to a thread, so that I can share it?

Highfive + Dolby Voice = No More Audio Complaints!

Poor audio quality is one of the top reasons people don’t use video conferencing. Get the crispest, clearest audio powered by Dolby Voice in every meeting. Highfive and Dolby Voice deliver the best video conferencing and audio experience for every meeting and every room.

Got it. Here it is:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=32180&lngWId=1

This worked a treat (first time & with the minimum of fuss!).

So I guess this question can now be closed. Thanks for your efforts.
