(4)VBA实现循环地调转到Wind点图层中中每一个点到地图窗口中心,每隔1秒钟跳转一次;

以下是VBA代码实现:
```
Sub ZoomToWindPoints()
Dim pMxDoc As IMxDocument
Set pMxDoc = ThisDocument
Dim pMap As IMap
Set pMap = pMxDoc.FocusMap
Dim pWindPointsLayer As ILayer
Set pWindPointsLayer = pMap.Layer(0) ' Wind点图层在地图中的位置
Dim pWindPointsFeatureLayer As IFeatureLayer
Set pWindPointsFeatureLayer = pWindPointsLayer
Dim pFeatureCursor As IFeatureCursor
Set pFeatureCursor = pWindPointsFeatureLayer.Search(Nothing, False)
Dim pFeature As IFeature
Set pFeature = pFeatureCursor.NextFeature
Do While Not pFeature Is Nothing
Dim pPoint As IPoint
Set pPoint = pFeature.Shape
pMxDoc.ActiveView.Extent.CenterAt pPoint ' 将地图窗口中心移动到当前点
pMxDoc.ActiveView.Refresh ' 刷新地图窗口
System.PrivateProfileString("", "HKEY_CURRENT_USER\Software\VB and VBA Program Settings\ZoomToWindPoints", "Interval") = "1000" ' 设置时间间隔为1秒
DoEvents ' 等待时间间隔
Set pFeature = pFeatureCursor.NextFeature
Loop
End Sub
```
该代码首先获取当前地图窗口中的Wind点图层,然后获取该图层中所有要素的游标。接着,代码循环遍历所有要素,将地图窗口中心移动到当前要素所在位置,并等待1秒钟后再继续下一个要素的遍历。注意,代码中使用了VBA内置函数“System.PrivateProfileString”来设置时间间隔,需要在注册表中进行相应设置。
