basic beginner code 1624 1
Started by Deleted User
Hello everyone,
I am very new to IDL programming. I have to subset 200 Global Aqua MODIS images to the extents of Madagascar and then export them as a binary files so I can bring the files into a GIS system by Dec 15!! I am still researching how to do this but given my time constraint I thought I would post here to see if anyone had any more tips and tricks.
Thanks!

Class Method calling another Method 1557 1
Started by Deleted User
Hi,
I've created an class object. In the ::init method I load some data into some pointers. I want to create another method, ::change_data, that would simply load another set of data into the object.
I'm not quite sure what would be the best method, but here is what I was thinking of:
calling the ::cleanup method to remove all the pointers
calling the ::init method that contains all the code to load the data
I've tried the following... but of course this doesn't work
pro shoalsObject::...

Updating from preview to New 7.0 Release problem 1816 2
Started by Deleted User
Updating to the 7.0 FINAL of 32bit windows version (idl70winx86_32.exe) from a preview version of IDL 7.0 does not seem to work properly. After the update, executing from command prompt within the DE gave us:
print, !Version.release
We found that it was necessary to uninstall IDL 7.0 from Add/Remove Programs AND delete the C:\Program Files\ITT\IDL70 folder.

urgent: Change startup file 1566 1
Started by Deleted User
Hi there
I'm working with IDL 5.6 on Win 2000. I recently changed my startupfile to a pro which has an undefined function, when I run it bevor. Now IDL starts up and immediately compiles and runs my corrupt *.pro - therafter the program hangs. Is there a way to change directories manually, when there is no access to the idlde
thanks a lot for immediate help
