DLL load failed with PyQGIS
Question: I've already asked this question in the "gis.stackexchange" forum, but it
seems to be more appropriate for this one.

I am having problems with Python Shell importing the module "qgis.core". When
I type "import qgis.core" the Shell ("idle.pyw") gives me this error:

    
    
    Traceback (most recent call last):
      File "<pyshell#0>", line 1, in <module>
        import qgis.core
    ImportError: DLL load failed: Impossibile trovare il modulo specificato (Trad "Impossible to find the specified module").
    

I have already set the environment to point the right folders following
"PyQGIS cookbook" instructions. In my case, the paths are:

PYTHOPATH=C:\"QGIS_path"\apps\qgis\python; Path=C:\"QGIS_path"\apps\qgis\bin.

Am I missing something? What are supposed to be the right libraries the Shell
is unable to find? I am working with windows 7 64 bit, QGIS Lisboa (version
1.8), Python 2.7.2 (the one that is included in the QGIS package).


Answer: I do not like to mix my python installations, so I add the paths on the fly.  
The paths you need are below:

    
    
    import sys
    sys.path.extend([r"C:\Program Files\QGIS Valmiera\apps",r"C:\Program Files\QGIS Valmiera\apps\qgis\bin",r"C:\Program Files\QGIS Valmiera\apps\Python27"])
    
    import qgis.core
