Unlocking a FeatureClass after edits

SachaTousignant

Hello everyone,

I'm trying to see if it's possible to unlock my FeatureClass after I added some features or modified some.

Here's some of the main lines :

IFeatureBuffer featureBuffer = infosXML.FeatureclassSitesReference.CreateFeatureBuffer(); IFeatureCursor cursorReferenceInsert = infosXML.FeatureclassSitesReference.Insert(true); featureBuffer.Shape = siteCourant.ShapeCopy; cursorReferenceInsert.InsertFeature(featureBuffer); cursorReferenceInsert.Flush();

Right now after doing this code, it locks the table from the others users.

EDIT :: It seems to be locked only when adding new features by either the way with FeatureBuffer + FeatureCursor or with FeatureClass.createFeature()
When modifying existing features and storing the changes, it doesn't lock the table.

try releasing featureBuffer and cursorReferenceInsert objects
e.g. in .Net, we can write Marshal.ReleaseComObject(cursorReferenceInsert)

Another way to release cursors is using the USING statement and ComReleaser. See the VB code below

' For ArcGIS 10 using VS 2010 you need to import the following
Imports ESRI.ArcGIS.ADF.Connection.Local
Imports ESRI.ArcGIS.ADF 
Dim pQueryFilter As IQueryFilter 
pQueryFilter= New QueryFilterClass
pQueryFilter.WhereClause = "ID = 1"
Using releaser As New ComReleaser 
    Dim pFeatureCursor As IFeatureCursor 
    pFeatureCursor = pFeatureclass.Update(pQueryFilter, True) 
    releaser.ManageLifetime(pFeatureCursor) 
    Dim pFeature As IFeature  
    pFeature = pFeatureCursor.NextFeature 
    While pFeature IsNot Nothing 
        ' Do something with pFeature 
        pFeatureCursor.UpdateFeature(pFeature) 
        pFeature = pFeatureCursor.NextFeature
     End While
End Using
