[ArcObjects]Define Projection...VBA

ArcToolBox의 Define Projection 은 하나의 레이어를 대상으로 하기때문에..

여러개의 레이어를 한번에 Define 할수 있는 VBA 입니다.

FeatureClass를 대상으로 하지만 IGeoDataset 인터페이스를 사용함으로 코드를 조금수정하면 Raster도 같은 방법으로 할수 있습니다.

Public Sub DefineProjection()
Dim sPrjPath As String
sPrjPath = "C:\XXXXXXX.prj"

Dim pSR As ISpatialReference
Dim pSRS As ISpatialReferenceFactory2
Set pSRS = New SpatialReferenceEnvironment
Set pSR = pSRS.CreateESRISpatialReferenceFromPRJFile(sPrjPath)

Dim pDoc As IMxDocument
Dim pMap As IMap
Set pDoc = ThisDocument
Set pMap = pDoc.FocusMap

Dim pLayers As IEnumLayer
Set pLayers = pMap.Layers

Dim pLyr As IFeatureLayer
Set pLyr = pLayers.Next

Dim pFClass As IFeatureClass
Dim pGeoDS As IGeoDataset
Dim pGeoDsSchemaEdit As IGeoDatasetSchemaEdit

Do While Not pLyr Is Nothing
Set pFClass = pLyr.FeatureClass
Set pGeoDS = pFClass
Set pGeoDsSchemaEdit = pGeoDS

Call pGeoDsSchemaEdit.AlterSpatialReference(pSR)
Set pLyr = pLayers.Next
Loop

MsgBox "Success~!!"
End Sub
