improved readability by adding necessary spacing after commas and new sentences. Formatted inline code. Corrected misuse of word in crucial point of question

| Feb 12, 2011 at 7:30 | comment | added | Reza | Yes Kirk,it's almost true,as you know plugin datasource is readonly and asume I want a toolbar like "Editor" for a plugin datasource or in my own case "OLEDB datasource",because editor toolbar doesn't get enabled for these datasources(and for custom layers too).Just now,I have my tools and extension for "My own editor",but I want to add snapping capability to my tools and for this,I need a cache of all geometries loaded in layers(or at least part of it around mouse cursor),so I don't have to query database while mouse movement.Is there anyway to access ArcMap cache for plugin-oledb features? | |
| Feb 11, 2011 at 15:44 | comment | added | Kirk Kuykendall | Please provide more details of your workflow. Perhaps you are trying to provide editing capabilities for a plugindatasource? If not maybe ask this question anyway: "How can I support editing of plugindatasources?" Perhaps this would provide an answer for you. Even though your particular requirements may differ, a more general question would attract more answers. | |

| Feb 11, 2011 at 8:48 | comment | added | Reza | Thank you Kirk,if I wan to cache a large number of features,I have 3 choices,1.OnClick tool 2.OnMouseDown 3.OnMouseMove the first 2 choices cause enduser encounters an hourglass mouse pointer for a long time which isn't acceptable for him,the third needs an algorithm which doesn't make any delay in mouse movement for tool,for example a right area around mouse cursor is cached and when cursor goes into another area cache gets refreshed,but I don't know how this mechanism must be implemented,using spatial indexing(like what sqlserver2008 uses) or using ISpatialFilter.Any idea o implement it? | |
| Feb 8, 2011 at 17:33 | comment | added | Kirk Kuykendall | If you have built a cache using ISpatialCacheManager, then GetFeature(10) will not issue a Select statement to the database, it will use what is already in memory. In other words caching is transparent. I'd be curious what happens if you cache a large number of features though. | |
