Below is the piece of code (an Add-In tool) I used for updating a feature layer loaded in a .mxd         void Update_Layer(IFeatureLayer sourceLayer, IFeatureLayer targetLayer)  {             IWorkspace ws = ((IDataset)targetLayer).Workspace;             IPropertySet propSet = ws.ConnectionProperties;             IVersion version = ((IVersionedWorkspace)ws).FindVersion(propSet.GetProperty("Version").ToString());                   // version - myTestversion             m_workspaceEdit = (IWorkspaceEdit)version;             ....          } The targetLayer loaded in .mxd is myTestVersion.  In this updating, the results show that the featureClass in both myTestVersion and SDE.Default got updated.  I only want to update myTestVersion.  I don't know why it happens.  Thanks if you can help. ...

I created an Add-Ins App using VS2012, FW4.5.  It works well on ArcMap 10.2 of my CPU.  However it does not work when it is loaded on other 2 CPUs. In one of CPUs, ArcGIS 10.2 (same version as my one), clicking the Add-In icon leads to the close of the ArcMap. In another CPU in which ArcGIS 10.4 Desktop is used.  After clicking on the tool icon, an error message pops out: "Add-In Version Not Match".  From the thread  Error: No GUI components found in this Add-In. Add-In version does not match , I checked the Config.esriaddinx file, in which   <Targets>     <Target name="Desktop" version="10.2" />   </Targets> Will the 10.2 be the problem of "Version Not Matched"? Thanks if you can share your experience. ... View more

This is .Net (Silverlight) program.  I want to add a Graphic item to a GraphicsLayer.  The related code is listed below             GraphicsLayer newGLyr = new GraphicsLayer();             for (int i = 0; i < gLayer.Graphics.Count; i++)     {                 Graphic g = gLayer.Graphics;                 if (!isDuplicate(newGLyr, g))                     newGLyr.Graphics.Add(g);             } However, I got the runtime error: Specified argument was out of the range of valid values.  Parameter name: Graphic is already associated with another layer.

The feature classes in my app are stored in our SDE for Oracle DB.  In Oracle SQL Developer, I can query tables in the DB.  However, I can't run SQL on a FeatureClass, e.g., like the SQL statement below:    SELECT * from myFCName Is it possible to do such a kind of query?  Thanks. ... View more

I created an Add-In project on VS2010.  When I run debugging after clicking the tool button on ArcMap, such an error pops out:   xxxx.pdb not loaded. Then, I checked the folder where the Add-In tool file locates, I could not see the xxx.pdb.  It means when I compile the project, the .pdb is not generated.  How can this problem be fixed?  Thanks. ...
