Hi,I guess this should work. You can exclude killifexistsraster function if you want, because it deletes the output raster without warning when you try it again.Dim pMxDoc As IMxDocument
Dim pMap As IMap
Dim pRasterLayer As IRasterLayer
Dim pRaster As IRaster
Dim pGeometryProc As IRasterGeometryProc
pMxDoc = My.ArcMap.Application.Document
pMap = pMxDoc.FocusMap
pRasterLayer = pMap.Layer(0)
pRaster = pRasterLayer.Raster
pGeometryProc = New RasterGeometryProc
pGeometryProc.Resample(rstResamplingTypes.RSP_NearestNeighbor, 7, pRaster)
Dim pDataset As IDataset
pDataset = pRasterLayer
Dim pWS As IWorkspace
pWS = pDataset.Workspace
Dim str As String
str = pWS.PathName
killifexistsRaster("try", str)
Dim RasterDataset As IRasterDataset
Dim pRasBandCol As IRasterBandCollection
pRasBandCol = pRaster
'pDS = pRasBandCol.SaveAs("try3", pWS, "GRID")
RasterDataset = pRasBandCol.SaveAs("try", pWS, "GRID")
