ArcGIS Engine 怎样给PageLayout替换模板
在打印出图时，常常需要更换已有的模板（mxt），这时数据并不改变。在ArcMap里面有一个替换模板的工具，但是在Engine里面却没有一个能直接替换模板的接口，而是需要读取新模板，取出模板里面的各个要素，然后替换掉原模板里面是相应要素。
Sub changelayout()
Dim pDoc As IMxDocument
Set pDoc = Application.Document
Dim pMap As IMap
Set pMap = pDoc.FocusMap
Dim pPageLayout As IPageLayout
Set pPageLayout = pDoc.PageLayout
'读取新模板
Dim pNewDoc As IMapDocument
Set pNewDoc = New MapDocument
pNewDoc.Open "C:Program FilesArcGISBinTemplatesLandscapeModern.mxt"
Dim pTempMap As IMap
Dim pTempPagelayout As IPageLayout
Set pTempPagelayout = pNewDoc.PageLayout
'Set pTempMap = pNewDoc.Map
Dim pTempPage As IPage
Set pTempPage = pTempPagelayout.Page
Dim pCurPage As IPage
Set pCurPage = pPageLayout.Page
'替换单位
pCurPage.Units = pTempPage.Units
'exchange page orientation
pCurPage.Orientation = pTempPage.Orientation
'替换页面尺寸
Dim dWidth As Double
Dim dHeight As Double
pTempPage.QuerySize dWidth, dHeight
pCurPage.PutCustomSize dWidth, dHeight
'删除当前Layout中除了mapframe外的所有elements
Dim pGraphicsCont As IGraphicsContainer
Dim pElement As IElement
Set pGraphicsCont = pPageLayout
pGraphicsCont.Reset
Set pElement = pGraphicsCont.Next
Do Until pElement Is Nothing
If TypeOf pElement Is IMapFrame Then
Dim pMapFrame As IMapFrame
Dim pMapFrameElement As IElement
Set pMapFrameElement = pElement
Set pMapFrame = pElement
Else
pGraphicsCont.DeleteElement pElement
pGraphicsCont.Reset
End If
Set pElement = pGraphicsCont.Next
Loop
'遍历模板的PageLayout中的所有元素，并且替换当前PageLayout中的所有元素
Dim pTempGraphicsCont As IGraphicsContainer
Set pTempGraphicsCont = pTempPagelayout
pTempGraphicsCont.Reset
Set pElement = pTempGraphicsCont.Next
Dim pArray As IArray
Set pArray = New esriSystem.Array
Do Until pElement Is Nothing
If TypeOf pElement Is IMapFrame Then
pMapFrameElement.Geometry = pElement.Geometry
Else
If TypeOf pElement Is IMapSurroundFrame Then
Dim pTempMapSurroundFrame As IMapSurroundFrame
Dim pTempMapSurround As IMapSurround
Set pTempMapSurroundFrame = pElement
Set pTempMapSurroundFrame.MapFrame = pMapFrame
Set pTempMapSurround = pTempMapSurroundFrame.MapSurround
pMap.AddMapSurround pTempMapSurround
End If
pArray.Add pElement
End If
Set pElement = pTempGraphicsCont.Next
Loop
Dim pElementCount As Long
pElementCount = pArray.Count
Dim i As Long
'将模板PageLayout中的其它元素（除了MapFrameElement和MapSurroundFrame外的元素）添加到当前PageLayout中去
For i = 0 To pElementCount - 1
pGraphicsCont.AddElement pArray.Element(pElementCount - 1 - i), 0
Next i
pDoc.ActiveView.Refresh
End Sub
