Ask an IDL Question
Typically, I am more than happy to answer IDL questions. I love to do it and I find it is a great way for me to learn more about IDL. But I am an IDL consultant and I write IDL programs for a living. Please do not ask me to:
- write a program for you
- look at more than short sections of IDL code (unless I ask to see it)
- explain a complicated topic in three paragraphs
Unless, of course, you are prepared to pay my consulting fee (which varies, but is usually affordable). If you send me an unsolicited e-mail with a 1 MByte attachment, you will never hear from me again and will certainly never make it out of my spam filter in the future.
I probably answer most e-mail questions on the day I receive them. Occasionally I am traveling and/or busy with my own projects and cannot take the time to answer immediately. I answer 99.9 percent of the e-mail that reaches me, eventually. (Sometimes e-mail gets caught by my spam filter and doesn't reach me. Having an informative subject line and including your signature block in the e-mail will help it get through.) Demanding an immediate answer (without including your credit card details) usually gets you pushed back to the end of the line and may delay an answer indefinitely.
If this is the first time you have asked an IDL question, please read the this article carefully. The quality of the answer you get may well depend on it.
The spammers have finally overwhelmed me and forced me to remove e-mail forms from my web page. You can send me e-mail here: david at dfanning dot com. Please put “IDL QUESTION” in the header, or its likely I won't see it. Sorry. I guess it is the price we pay for an unregulated Internet. :-(
