Could not commit changes to layer X You are definitely correct to recommend saving after each edit. However there seems to be some bugs in the table calculation capability or I am still green enough that I do not understand how it really works. Some of both I think. As of now, I do not see the value of the default to integer arithmetic needing to multiply by 1.0 to get floating point results. No other software I use works this way. |

How to change position of columns in attribute table? I misunderstood what you were saying. I just tried to find TableManager and I found the .zip on pyqgis.org/repo/contributed however it does not appear in my plugin manager list which includes the offical one. I have had this problem before, Sextante did not appear until I used QGIS on another machine. Never did install it correctly. |

Could not commit changes to layer X I tried opening what was left in Excel and Open Office, the file was toast. Saving after every column entry sounds reasonable. So the .shp file's .dbf is not altered (the table is in memory) until is is saved? Seems some operations work on the original file whether one saves or not, otherwise a save is required. Is that correct? |

How to change position of columns in attribute table? I have had mixed results with fooling with the .shp file's .dbf. And once it gets altered there seems to be no recovery. If I had my files in a spatial database (which I know nothing about) would I be able to arrange the columns? |

FIeld calculator gives integer not a real as requested Yes that works. It seems that it would be better to not do integer calculations except unless mod() functions are used. The default should be floating point and not dependent on the variable type. |

FIeld calculator gives integer not a real as requested Thank you! and ("F06_POPULA" - "POPULATION") /toreal( "POPULATION") Got to have a floating point in there somewhere. Also multiplying by 1. will not work, but 1.0 does work. |
