>File.Delete(def)
>File.Delete(def.GetFullName.SubStitute("shp","shx").AsFilename)
>
>I can not delete the corresponing DBase file:

>If (File.CanDelete(def.GetFullName.SubStitute("shp", "dbf").AsFilename)) Then
>      File.Delete(def.GetFullName.SubStitute("shp", "dbf").AsFilename)
>End

Thanks to:

Greg, Günther, Sara, Patrick, Kevin, P. G. L., Christoph Farley and Subhani.

Last not least to ESRI-Germany for pointing to a solution provided by ESRI
online support at:

http://support.esri.com/search/KbDocument.asp?dbid=12600

According to my experiences, a restart of the project might be helpful,
before this solution can be applied successfully.

Cheers,

Uwe
