Re: [Qgis-user] automatically reload (csv) file

Hi Delazj, Yes - I was assuming that people would use the "Add delimited text layer tool". Sorry - I forgot to mention that. It is more flexible and easier to use than the "Add vector layer" dialogue. About CSV, joins and updates: have you checked the cache vs. uncached option for your

[Qgis-user] automatically reload (csv) file

Hi, how (often) does QGIS read features from a file (like csv or shape - differences?)? I realize I do not really know how the datasource - qgis- communication goes. Imaine you have a csv or shape file that is loaded into QGIS but is automatically replaced from time to time (or lets say
