ARCGIS9.3 字段计算器 VAB ----怎么在字段的后面统一加6个0 ?

这个很简单,在属性表中进行字段运算就可以了
dim pQueryFilter as IQueryFilter
set pQueryFilter = new QueryFilter
pQueryFilter.where....组织你的条件
dim pFClass as IFeatureClass
set pFClass= 你传入的图层FeatureClass
dim pFCursor as IFeatureCursor
set pFCursor= pFClass.Search(pQueryFilter,false)
dim pFeature as IFeature
set pFeature= pFCursor.NextFeature()
循环记录,并启动编辑,加上代码(IWorkspaceEdit.StartEditing )
while not pFeature is nothing
pFeature.某个字段.value=pFeature.字段A + pFeature.字段B +....
set pFeature= pFCursor.NextFeature()
pFeature.store
wend
停止编辑(pWorkspaceEdit.StopEditing )
dim pQueryFilter as IQueryFilter
set pQueryFilter = new QueryFilter
pQueryFilter.where....组织你的条件
dim pFClass as IFeatureClass
set pFClass= 你传入的图层FeatureClass
dim pFCursor as IFeatureCursor
