Tom, I'm sorry I didn't realize that there is one file type where this problem happens! I use CSV files so rarely myself that I didn't think of them.
Unfortunately, CSV files are read-only for most purposes. The reason is that if you were to change a value in one cell, the entire table from that point on would have to have to be rewritten. This is different from other formats (dBase, Fixed format binary, Fixed format ASCII), which have the room in the file. I'm in complete agreement with you that it is a awkward that Maptitude allows you to add a column to the file, but not to modify it. I'll make sure this gets passed on to the right people. If nothing else, the user should be warned that adding a column to a CSV file will result in an un-editable column. -Kjartan -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of bjs_market_research Sent: Tuesday, May 10, 2005 3:56 PM To: [email protected] Subject: [Maptitude] Re: Read-Only Columns I created a point file from a .csv file. Opened it for exclusive access, but when I added a column from the modify table/add field it was read-only. There were no instructions given by me to make anything read-only: Maptitude decided that on its own. The only fix was to rebuild the file. I can't figure out why anyone would want to add a column to a table and not be able to update it. ------------------------ Yahoo!
