Hi, i tried to run bat file (C:\OSGeo4W\OSGeo4W.bat), close ms-dos shell and run python

???If you close the shell you loose the environmental variables.OSGeo4W.bat sets env vars for the current shell, they're not kept as system env vars.
 You need those environmantal variables to leaverage the osgeo4w libraries.You ha mainly three choices:
 - run your python script inside a shell where you have setup the env variables (like it is done by Osgeo4W.bat)
 - hard code the environmental variables inside your python script and add them to os.environ, and set the path to the python modules with sys.path - make the various environmantal variables statically availables as system env vars (Control Panel -> Systems -> etc.)

Hi Francesco,are you using osgeo4w? In that case I suggest you to have a look to the startup .bat files (like C:\OSGeo4W\OSGeo4W.bat), that setup the right evnironment (python pat, bin dires, etc.)


In general you have to add the various Qt and Qgis DLLs to the PATH, and configure the python paths to be able to peak the qgis modules.
