[Gdal-dev] Beginner problem - can't load DLL

[=?gb2312?B?2k+9qMP3?=]

to Mateusz Loskot:

thank you very much!
I'm sorry to my unclearly language.
I use the IDE PythonWin.
According to your direction i have solved my problem.
It's really like you say,i have set the Python path but not set the OS's Path to search my dll,so the problem occur.
Thanks again!

What do you mean "my IDE"?

What's Tools|Edit?

I suppose the problem is that GDAL DLL can't be found by your IDE,
whatever the IDE means.
Try to add path where GDAL DLL file lives to system-wide or user's
PATH environment variable.
sys.path represents Python's PYTHONPATH, not Windows PATH where exe and
dll files are searched for.

Alternatively, you can try to open FWTools command line (use shortcut in
Start Menu - > FWTools) and run your IDE from command line, then it should
inherit PATH settings from FWTools shell.
