FAQ: How many grids can be open at one time in a Visual Basic session?
How many grids can be open at one time in a Visual Basic session?
Only 50 rasters of the ESRI GRID format can be open at one time in a Visual Basic session in pre-ArcGIS 9.0 versions.
As a workaround for pre-ArcGIS 9.0 versions, if there are temporary grids, save some of them to disk and set the temporary grid object to nothing. Also, close some of the open grids and open them only when it is necessary to access them.
At ArcGIS 9.0 the above limits have been removed.
- How many grids can be created within a Visual Basic subroutine?
- What is the limit of ESRI GRID format rasters that can be added to ArcMap at one time?
