为什么从vbscript调用宏时出现类型不匹配错误

Question

当我从vbscript调用下面的宏时，为什么我遇到类型不匹配错误

parameter.xlsm中的宏

Sub Proc(sParam1 As String, iParam2 As Integer)
MsgBox sParam1 & " is " & iParam2 & " Years Old"
End Sub

VB脚本代码

Dim objExcel,objWorkbook

Set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Open("C:\ExcelFiles\parameter.xlsm")
sParam1 = Inputbox("Enter the first parameter")
iParam2 = Inputbox("Enter the second parameter")
iParam3= CInt(iParam2)

objExcel.Application.Visible = True

objExcel.Application.Run "parameter.xlsm!Proc",sParam1,iParam3
objExcel.ActiveWorkbook.Close

objExcel.Application.Quit
WScript.Echo "Finished."
WScript.Quit

Answer 1

在您的过程中，您正在连接字符串，但是第二个参数是整数类型。 您需要先使用CStr（）函数将其转换为字符串

Sub Proc(sParam1 As String, iParam2 As Integer)
MsgBox sParam1 & " is " & CStr(iParam2) & " Years Old"
End Sub

尝试在vbscript中显式声明您的变量...我也习惯了在工作簿代码中使用很long 。

parameter.xlsm中的代码：

Option Explicit
Sub Proc(sParam1 As String, iParam2 As Long)
    MsgBox sParam1 & " is " & iParam2 & " Years Old"
End Sub

VBScript代码：

Dim objExcel As Object
Dim objWorkbook As Workbook
Dim sParam1 As String
Dim iParam2 As Long, iParam3 As Long

Set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Open("C:\ExcelFiles\parameter.xlsm")
sParam1 = InputBox("Enter the first parameter")
iParam2 = InputBox("Enter the second parameter")
iParam3 = CInt(iParam2)

objExcel.Application.Visible = True

objExcel.Application.Run "parameter.xlsm!Proc", sParam1, iParam3
objExcel.ActiveWorkbook.Close

objExcel.Application.Quit
WScript.Echo "Finished."
WScript.Quit
