.net provider to geodatabase fails when run from windows service

BruceCheney — Mon, 14 Nov 2011 15:59:42 GMT

For a variety of operations we load geodatabase layer tables into .net datasets as datatables. We use the data providers from esri to make this connection. The connection is as follows:

projConn = New OleDb.OleDbConnection("Provider=ESRI.GeoDB.OleDB.1;Data Source=" & daPath & ";Extended Properties=workspacetype=esriDataSourcesGDB.FileGDBWorkspaceFactory.1;Geometry=WKB")

And then to fill the dataset:

layDAdbf = New OleDb.OleDbDataAdapter
layDAdbf.FillSchema(daDataset, SchemaType.Mapped, layername)
layDAdbf.Fill(daDataset, layername)

This has worked for many years in a variety of product usages. We are now trying to use this from a Windows Service. It works in a console app, a scheduled task but not in a windows service. It always fails on the fill statement. With a File Geodatabase the program just ends - no error reporting even with a try-catch. The Windows event viewer reports the following:

Faulting module name: ntdll.dll, version: 6.1.7600.16695, time stamp: 0x4cc7ab86
Exception code: 0xc0000005

There appears to be many possible causes for this exception. Does anyone have any comments or suggestions - have you run into this issue.

Any help is greatly appreciated.

Is your service run on x64? If yes you got an "The 'ESRI.GeoDB.OLEDB.1' provider is not registered on the local machine" exception.
