Failed to rename the specified file

Error Message

This error occurs when using the MakePermanentAs method to make a temporary output from a spatial analyst function into a permanent raster (grid):

“Failed to rename the specified file”

Cause

This happens when the permanent output file specified is a grid raster dataset and is in the same directory as the temporary output. MakePermanentAs does not make another copy of the grid, instead, it renames the temporary grid. If the references to the grid are not released before calling MakePermanentAs, an error will occur.

Solution or Workaround

• Use the SaveAs method instead of MakePermanentAs:
  
  

  Code:
  Dim pRBC As IRasterBandCollection
  Set pRBC = pOutGDS  '-- pOutGDS is a IGeoDataset generated from a SA function
  Dim pDS As IGeoDataset
  Set pDS = pRBC.SaveAs("test2", pWs, "TIFF")

  
  
• Release the references to the temporary grid, then call MakePermanentAs:
  
  

  Code:
  Public Function MakePermanentAs(pSAOutRaster As IRaster)
      '-- pSAOutRaster is a Raster Object from a Spatial operation
      Dim pRasBC As IRasterBandCollection
      Set pRasBC = pSAOutRaster
      
      '-- Get the dataset from the first band
      Dim pOutDS As IRasterDataset
      Set pOutDS = pRasBC.Item(0).RasterDataset
  
      '-- QI the dataset for ITemporaryDataset
      Dim pTemp As ITemporaryDataset
      Set pTemp = pOutDS
  
      '-- Release the raster before making the dataset permanent
      Set pRasBC = Nothing
      Set pOutGDS = Nothing
      
      Dim pDS As IDataset
      Set pDS = pTemp.MakePermanentAs("c:\temp\outgrd", Nothing, "GRID")
  End Function
