在arcmap+vba中使用arcgis中的toolbox中的工具

在VBA中或者VB中用IGeoProcessor接口中的Execute方法可以调用arcgis中所有Toolbox工具。
GP.Execute的命令名称格式如下：“工具名称（toolbox中的名称）”+下划线+所在工具集的假名。如“MosaicToNewRaster_management”
下面例子中调用了MosaicToNewRaster工具--镶嵌栅格数据
Set GP = New GeoProcessor
        Set VA = New VarArray
        GP.OverwriteOutput = True
            outputPath = Left(ListBox.List(i), Len(ListBox.List(i)) - 1)
            tmpNum = InStrRev(outputPath, "\", -1, vbTextCompare)
            mytmpname = Right(outputPath, Len(ListBox.List(i)) - tmpNum - 1)

        VA.Add inputPath
        VA.Add outputPath
        VA.Add tifName
        VA.Add "#"
        VA.Add "8_BIT_UNSIGNED"
        VA.Add "#"
        VA.Add "3"
        VA.Add "LAST"
        VA.Add "FIRST"
       
        GP.Execute "MosaicToNewRaster_management", VA, Nothing

'===初始化GeoProcessor

Dim GP As IGeoProcessor
Set GP = New GeoProcessor

'===输出时覆盖同名文件
GP.OverwriteOutput = True

'//Declare 3 variables for input and output parameters
Dim inputPath As String
Dim outputPath As String
Dim tifName As String

'//定义参数
inputPath = "D:\TEST\Input1.TIF;D:\TEST\Input2.TIF"
outputPath = "D:\TEST"
tifName = "MOS.tif"

'//设置变量数组
Dim VA As IVariantArray

Set VA = New VarArray
    VA.Add inputPath ’==输入的栅格文件
    VA.Add outputPath ’==镶嵌后输出的栅格文件路径
    VA.Add tifName ’==镶嵌后的文件名
    VA.Add "#" ’==定义座标系统
    VA.Add "8_BIT_UNSIGNED" ’==输出的位数
    VA.Add "#" ’==单元格大小
    VA.Add "3"’===波段
    VA.Add "LAST"   ’ ===重叠区域处理方法
    VA.Add "FIRST" ’ ===色带处理方法

'=====执行工具

 GP.Execute "MosaicToNewRaster_management", VA, Nothing
