I'm currently working on a ArcObjects C# project that will repoint datasources for layers of various types. Basically a database is maintained that holds the old datasource connections and the new connections. When the user presses a button, the application goes through all the current layers in ArcDesktop and compares the layers current datasource with the new one. If there is a difference, it resets the datasource.
However, I'm not quite sure how to access the datasource, and in my perusings of this stackexchange, I noticed someone who was working on something similar, but they were using raster layers. I'm not too familiar with ArcGIS and didn't know if I needed to handle feature layers differently as he mentions he already found a solution for feature layers.
Here's the section I'm trying to change in ArcDesktop:
I have everything working just fine except the changing of those datasources. I found this resource on arcgis, but it doesn't appear to change those strings, though I could be mistaken.
This is what I currently have:
//Loop through all layers and get their information pEnumLayer.Reset(); pLayer = pEnumLayer.Next(); while (pLayer != null) { Log.Debug("Manipulating the layer: " + pLayer.Name); IDataLayer dataLayer = (IDataLayer)pLayer; var datasource = dataLayer.DataSourceName; // this is what I believe to be the current datasource Log.Debug("Repaired layer: " + pLayer.Name); pLayer = pEnumLayer.Next(); } Is that the correct datasource I'm looking for? If so, would all I need to do to change the datasource is to set that variable to the new datasource string and then redraw the map?
