As Richard Younger and Gert suggested last time, we can specify the
IDLDE executable through
project->settings->debug: fill in idl_path\idl32.exe

But in my IDL program, I use some ENVI functions, so I use IDL in ENVI
environment, actually the executable this time should be:
D:\RSI\ENVI34\IDL54\bin\bin.x86\idlde.exe -minimized
@"D:\RSI\\envi34\bin\envi.run"

But how can I set executable including parameters in Visual C++? If I
set it as
D:\RSI\ENVI34\IDL54\bin\bin.x86\idlde.exe -minimized
@"D:\RSI\\envi34\bin\envi.run", VC can not recognize it.

Any suggestion will be appreciated!

Set !Except=2 and run your program. You will get an error
now when it happens instead of a message.

Cheers,

Have a lookee at the !EXCEPT system variable. That should help debug this sort of thing.

Thanks a lot, the error was generated because I was using "linfit".
Thanks for the help!
