Presentación
In prefix syntax, WINDEV and WEBDEV allow you to handle Excel files by Handling the XLS and XLSX worksheets dynamically.
This method uses different types of variables as well as WLanguage functions. This method allows you to manage the Excel files (XLS or XLSX files) in read and write mode.
Gestión dinámica de los archivos XLS y XLSX
To handle the XLS and XLSX files, the WLanguage proposes:
  • different types of variables. These types of variables are used to handle an XLS document, an XLS row or column, an XLS cell.
  • several WLanguage functions that handle the different types of data.
To handle the XLS and XLSX files:
  1. Declare a variable of type xlsDocument. This type of variable is used to describe and modify an Excel document.
  2. If necessary, open the XLS file (function xlsOpen) and link it to the Variable of type xlsDocument.
  3. The different elements in the Excel document can be handled:
    • with the WLanguage functions.
    • or with properties of the type xlsDocument .
Example:
MyXLSFile is xlsDocument
AFile is string
AFile = fExeDir + "\Business info1.xls"
 
MyXLSFile = xlsOpen(AFile, xlsWrite)
IF ErrorOccurred = False THEN
Azz is int = MyXLSFile..Worksheet
Info("Current worksheet in the Excel file: " + Azz)
// Change worksheet
IF MyXLSFile..Worksheet = 2 THEN
Info("The current worksheet was modified.")
// Read a cell for test
Info(xlsData(XLSFileID, 11, 2))
ELSE
Error("The selected file does not include a second worksheet!")
END
ELSE
Error("Caution, the file is already opened on a computer!")
END
Remarks:
  • If the Excel file is opened in read/write mode (xlsWrite constant), the file is opened and locked until it is closed. To save the modifications performed, use xlsSave.
  • The XLS functions do not require "Microsoft Excel" to be installed on the user computers.
  • The XLS files and the files specific to Office 2007 (.xlsx files) are supported.
Versión mínima requerida
