Hi there. Yhis is my first post and I hope someone can help me.

I'm having a problem with QProcess. I'm trying to execute pg_dump (PostgreSQL backup generator) from my application.

I added the agument list containing information about user, host, etc. and setted the enviroment variables to store the password.

I captured the output and received a message from pg_dump that says:

Qt Code: 
  1. pg_dump: [archiver (db)] connection to database "sgtnewnew" failed: could not translate host name "localhost" to address: Unknown host
  2. pg_dump: *** aborted because of error
To copy to clipboard, switch view to plain text mode 

The command line I used was:

Qt Code: 
  1. C:\Arquivos de programas\PostgreSQL\8.2\bin>pg_dump.exe -i -h localhost -p 5432 -U postgres -F c -b -v -f C:\testeBat1.backup sgtnewnew
To copy to clipboard, switch view to plain text mode 

I made many tests and it seams that pg_dump.exe has not found it dependencies or something else. I tried to create a .bat file and place it in the postgres/bin folder and then call it using QProcess. I got the same error message. When I ran this .bat file by clicking twice over it, the backup was sucessfully done.

I tried to run it using system(c++ function) and it worked fine. The problem is that I need to capture the output (stdout) and QProcess does it for me.

Dows anyone had any problem like this??

Thans for now
