Example

The following example demonstrates how the GridStatistics object is used in relation to the Grid object.

Sub Main

'Declares SurferApp as an object

Dim SurferApp As Object

'Creates an instance of the Surfer Application object and assigns

'it to the variable named "SurferApp"

Set SurferApp = CreateObject("Surfer.Application")

'Makes Surfer visible

SurferApp.Visible = True

'Declares Grid as an object

Dim Grid As Object

'Creates a new grid and assigns it to the variable named "Grid"

Set Grid = SurferApp.NewGrid

'Loads a grid file to the variable named "Grid"

Grid.LoadFile(FileName:=SurferApp.Path+"\Samples\demogrid.grd", HeaderOnly:=False)

'Creates a new grid statistics object and assigns it to the variable named "GridStatistics"

Set GridStatistics = Grid.Statistics

End Sub
