hi chris, i'd like to use your plugin to have in my project just one original shape file and many copies of that in order to make analysis and layout within a subset of it. what i see is: 1) when a memory layer is created is not possible to make a selection of subset by means of "query builder" in layer properties-->general tab 2) when i save the project and re open, memory layer is in the toc but it doesn't have any features. is it right or i'm doing some errors? thank you in advance s. ________________________________ FROM Chris Crook Subject: MemoryLayerSaver plugin? Hi Stefano 1) The memory layer provider doesn't have support the query builder - this is just the way it is coded. I guess you could make a feature request for that to be added to QGIS 2) By default QGis doesn't retain the contents of memory layers when the project is closed - as you see it keeps the definition of the layer in the table of contents, but loses the data. This is not an error on your part, it is just the design of the memory layer. This is what the MemoryLayerSaver plugin is for ... once it is installed it should save the contents any memory layers...
