This article pertains to ArcGIS versions 8.x and 9.x. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools.

This article provides a sample of looping through a text file using ArcObjects.

Support for Visual Basic for Applications (VBA) for ArcMap and ArcCatalog ended with the ArcGIS 10.2.2 release, and Esri has not included VBA compatibility setups since version 10.5. See: ArcGIS Desktop and VBA Moving Forward

Set pStandTab = pStandColl.StandaloneTable(0)
Set pTable = pStandTab
Dim pRow As IRow, pCursor As ICursor
Set pCursor = pTable.Search(Nothing, False)
Set pRow = pCursor.NextRow
