Dear,
There are about 200 shape files, which I want to add the same field in the attribute table called GID1.
I want to implement it in ArcCatalog and prepared a code below.
However, it is for one shape file each time.
Please kindly help to modify it for multiple shape files (within the same folder) in a run.
Thanks.
Code
Public Sub AddField()
' Part 1: Define the workspace
Dim pApp As esriCatalogUI.IGxApplication
Set pApp = esriArcCatalog.Application
Dim pGxSelection As esriCatalog.IGxSelection
Set pGxSelection = pApp.Selection
Dim plist As esriCatalog.IEnumGxObject
Set plist = pGxSelection.SelectedObjects
Dim pGxObject As esriCatalog.IGxObject
Dim pName As esriSystem.IName
Dim pDS As esriGeoDatabase.IDataset
Dim pFE As esriGeoDatabase.IFieldEdit
Dim pGDSE As esriGeoDatabase.IGeoDatasetSchemaEdit
Dim pStatusBar As esriSystem.IStatusBar
Set pStatusBar = esriArcCatalog.Application.StatusBar
Dim pTable As ITable
Dim pFeatureLayer As esriCarto.IFeatureLayer
Dim pFeatureClass As esriGeoDatabase.IFeatureClass
Dim pGxDataset As esriCatalog.IGxDataset
' Part 2: Delete the field
' Define the first new field.
Dim pFields As IFields
Dim ii As Integer
Dim pField3 As IField
' Define the second new field.
Dim pField2 As IFieldEdit
Set pField2 = New Field
pField2.Name = "GID2"
pField2.Type = esriFieldTypeString
pField2.Length = 6
Set pGxObject = plist.Next
If TypeOf pGxObject Is IGxDataset Then
Set pGxDataset = pGxObject
Set pFeatureLayer = New FeatureLayer
Set pFeatureLayer.FeatureClass = pGxDataset.Dataset
Set pFeatureClass = pFeatureLayer.FeatureClass
Set pFields = pFeatureClass.Fields
ii = pFields.FindField("GID1")
Set pField3 = pFields.Field(ii)
End If
If pGxObject Is Nothing Then
MsgBox "You need to select the files", vbOKOnly, "Error"
Else
' Add the new field
pFeatureClass.AddField pField2
MsgBox "fields added.", vbOKOnly + vbInformation, "Add GID1"
End If
Exit Sub
ErrorHandler:
MsgBox "AddGID1: " & Err.Number & "-" & Err.Description, vbCritical, "Add GID1"
End Sub
