Hello:
to read an excel file, I always used the following:

Code: Select all

XIncludeFile "E:\install\dvd1\dev_soft\purebasic\extra\COMatePLUS\COMatePLUS.pbi"

Declare.s read_excel(fname.s,sheet.s,col.u,lig.u)
Debug read_excel("e:\my_data\xlw\banque.xls","banque",1,15)
End

Procedure.s read_excel(fname.s,sheet.s,col.u,lig.u)
Define.COMateObject ExcelObject, WorkBook, Worksheet
Define result.s
ExcelObject = COMate_CreateObject("Excel.Application")
If ExcelObject
  Lookin$ = "Workbooks\Open('"+fname+"')"
  WorkBook = ExcelObject\GetObjectProperty(Lookin$)
  If WorkBook
    WorkSheet = ExcelObject\GetObjectProperty("Sheets('"+sheet+"')")
    If WorkSheet
      WorkSheet\Invoke("Activate()") 
      result = ExcelObject\GetStringProperty("Cells("+Str(lig)+"," + Str(col) + ")" )    ; Cells(Row,Column)
    Else
      MessageRequester("COMate ", "error ExcelObject\GetObjectProperty(Sheets)")       
    EndIf
  Else  
    MessageRequester("COMate ", "error ExcelObject\GetObjectProperty(Workbooks\Open)")      
  EndIf
Else
  MessageRequester("COMate ", "error COMate_CreateObject")  
EndIf
WorkSheet\Release()
WorkBook = ExcelObject\GetObjectProperty("Workbooks\Close")
ExcelObject\Invoke("Quit()")
ExcelObject\Release()
ProcedureReturn result
EndProcedure

But I'm not sure if that's what you're searching for.
HTH.
