I writed a window Service using pywin32, In the Service , I use Basemap to draw a map of B,but it can't work.

the code is like above. the code in red block can work,but when it comes to the green block, the code can't go on , in other word , the code doesn't post a error message , so the procedure isn't killed. just like freeze.

the window Service written by Python is just like above. but ,when i put the code as a Python Script,just like below:

I don't know much about windows services, but I will point out an observation. The call to map_B.readshapefile(...) in your service code will implicitly trigger a window creation via matplotlib. Depending on how your install is done and other things, this means a GUI framework is triggered. I don't know if that is allowed within a service. Perhaps if you added something along the lines of:

import matplotlib
matplotlib.use('agg')

at the top of the script to force a non-interactive backend, maybe the hang will go away?
