DraftSight Lisp - 查找 Excel Sheet

Question

我正在尝试使用 Lisp 达到单元格级别来操作 sheet 中的值。我目前从 this code 开始工作到 GitHub。但是，我运行遇到了提取 sheet 名称的问题。我可以获得工作簿中 sheet 组的对象变量，但我无法访问单个 sheet。这段代码需要怎么写才能找到正确的sheet?

;;; Global Variables
(setq *ExcelApp% nil)
(setq *ExcelData@ nil)
(setq *ExcelFile$ nil)

;;; Debug Use
(defun C:ExcelTest()
    (princ "\n \n \n")
    (setq FilePath "C:\DUP\Temporary.xlsx")
    (vl-load-com)
    (setq NewList (GetExcel FilePath "Sheet1" "3D"))
    (setq GlobalList *DataList@)

    (terpri)
    (princ "New List : ")(princ NewList)(terpri)
    (princ "\n \nGlobal List : ")(princ GlobalList)(terpri)
);defun C:ExcelTest
;-------------------------------------------------------------------------------
; GetExcel - Stores the values from an Excel spreadsheet into *ExcelData@ list
; Arguments: 3
;   ExcelFile$ = Path and filename
;   SheetName$ = Sheet name or nil for not specified
;   MaxRange$ = Maximum cell ID range to include or nil to get the current region from cell A1
; Syntax examples:
; (GetExcel "C:\Temp\Temp.xls" "Sheet1" "E19") = Open C:\Temp\Temp.xls on Sheet1 and read up to cell E19
; (GetExcel "C:\Temp\Temp.xls" nil "XYZ123") = Open C:\Temp\Temp.xls on current sheet and read up to cell XYZ123
;-------------------------------------------------------------------------------

;;; Pulls values from Excel
(defun GetExcel (ExcelFile$ SheetName$ MaxRange$ / Column# ColumnRow@ Data@ ExcelRange^
    ExcelValue ExcelValue ExcelVariant^ MaxColumn# MaxRow# Range$ Row# workbook Worksheet)
    
    (terpri)
    (princ "GetExcel started...\n")

    ;; Verifies Excel file input
    (if (= (type ExcelFile$) 'STR)
        (if (not (findfile ExcelFile$))
            (progn
                (alert (strcat "Excel file " ExcelFile$ " not found."))
                (exit)
            );progn
        );if
        (progn 
            (alert "Excel file not specified.")
            (exit)
        );progn
    );if
    
    (princ "File verified...\n")

    ;; Garbage collection / Lisp compatability
    (gc)
    
    ;; Initializing Excel variable
    (if (not (setq *ExcelApp% (vlax-get-object "Excel.Application")))
    (progn; True - Error Catch
        (alert "Close all Excel spreadsheets to continue!")
        (vlax-release-object *ExcelApp%)(gc)
    );progn
    );if

    ;; Opening the Excel workbook
    (setq ExcelFile$ (findfile ExcelFile$))
    (setq *ExcelApp% (vlax-get-or-create-object "Excel.Application"))
    (setq workbook (vlax-invoke-method (vlax-get-property *ExcelApp% 'WorkBooks) 'Open ExcelFile$))
    
    (princ "\nWorkbook opened...\n")

    ;; Debug Print
    (princ (vlax-get-property (vlax-get-property *ExcelApp% "Names") "Parent"))
    (princ "\n \n")
    (vlax-dump-object workbook)

    (vlax-dump-object (vlax-get-property *ExcelApp% "Sheets"))
    (princ "\n \n")
    
    ;; Finds the worksheet in the Excel workbook
    (if (> (sslength SheetName$) 0)
    (vlax-for Worksheet (vlax-get-property workbook "Sheets")
        (princ "Worksheet : ")
        (vlax-dump-object Worksheet)
        (if (= (vlax-get-property Worksheet "Name") SheetName$)
            (vlax-invoke-method Worksheet "Activate")
        );if
    );vlax-for
    );if
    
    (princ "Specific Problem Solved\n")
);defun GetExcel

不是使用 (vlax-for Worksheet (vlax-get-property workbook "Sheets") 来拉取每个 sheet，而是调用 "Item" 并在 vlax-get-property 函数的末尾添加一个数字来拉取每个 [= sheet 列表中的 16=]。更新后的代码部分如下所示。

;; Finds the worksheet in the Excel workbook
(setq Sheets (vlax-get-property Workbook "Sheets"))
(setq shCount (vlax-get-property Sheets "Count"))
(setq iInt1 0)
(if (> (sslength SheetName$) 0)
    ;(vlax-for Worksheet (vlax-get-property workbook "Sheets")
    (while (>= shCount (setq iInt1 (1+ iInt1)))
        (setq Worksheet (vlax-get-property Sheets "Item" iInt1))
        (if (= (vlax-get-property Worksheet "Name") SheetName$)
            (vlax-invoke-method Worksheet "Activate"));if
    );while
    ;);vlax-for
);if
