Problem mit einer function( excel in stringgrid)

[NikoMitDaMacht]

Hallo!

Ich ein grosses problem mit folgender fuction:
von http://www.advdelphisys.com/Code_Lib...pyToStringGrid

Delphi-Quellcode:

Function ExcelCopyToStringGrid( 
  Excel                 : Variant; 
  ExcelFirstRow         : Integer; 
  ExcelFirstCol         : Integer; 
  ExcelLastRow          : Integer; 
  ExcelLastCol          : Integer; 
  StringGrid            : TStringGrid; 
  StringGridFirstRow    : Integer; 
  StringGridFirstCol    : Integer; 
  SizeStringGridToFit   : Boolean; {Make the StringGrid the same size as the input range} 
  ClearStringGridFirst  : Boolean  {cells outside input range in StringGrid are cleared} 
  ): Boolean; 
Var 
  C,R : Integer; 
Begin 
  Result := False; 
  If ExcelLastCol < ExcelFirstCol Then Exit; 
  If ExcelLastRow < ExcelFirstRow Then Exit; 
  If (ExcelFirstRow < 1) Or (ExcelFirstRow > 255)   Then Exit; 
  If (ExcelFirstCol < 1) Or (ExcelFirstCol > 30000) Then Exit; 
  If (ExcelLastRow  < 1) Or (ExcelLastRow > 255)    Then Exit; 
  If (ExcelLastCol  < 1) Or (ExcelLastCol > 30000)  Then Exit; 
  If StringGrid = nil   Then Exit; 
  If SizeStringGridToFit Then 
  Begin 
    StringGrid.ColCount := ExcelLastCol - ExcelFirstCol + StringGridFirstCol + 1; 
    StringGrid.RowCount := ExcelLastRow - ExcelFirstRow + StringGridFirstRow + 1; 
  End; 
  If ClearStringGridFirst Then 
  Begin 
    C := StringGrid.ColCount; 
    R := StringGrid.RowCount; 
    StringGrid.ColCount := 1; 
    StringGrid.RowCount := 1; 
    StringGrid.Cells[0,0] := ''; 
    StringGrid.ColCount := C; 
    StringGrid.RowCount := R; 
  End; 

  Result := True; 
  For R := ExcelFirstRow To ExcelLastRow Do 
  Begin 
    For C := ExcelFirstCol To ExcelLastCol Do 
    Begin 
      Try 
        StringGrid.Cells[ 
          C - ExcelFirstCol + StringGridFirstCol, 
          R - ExcelFirstRow + StringGridFirstRow] := 
            Excel.Cells[R, C]; 
      Except 
        Result := False; 
      End;

Hallo,
ich habe mich schon mal mehrere Wochen mit Excelautomation herumgeschlagen, das macht nicht wirklich Spaß, weil vor allem alles soooo wunderbar dokumentiert ist...

Auf jeden Fall, die Lösung Deines Problems:

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, Grids, comobj;

type
  TForm1 = class(TForm)
    Button1: TButton;
    StringGrid1: TStringGrid;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

Function ExcelCopyToStringGrid(
  Excel                 : Variant; 
  ExcelFirstRow         : Integer; 
  ExcelFirstCol         : Integer; 
  ExcelLastRow          : Integer; 
  ExcelLastCol          : Integer;
  StringGrid            : TStringGrid;
  StringGridFirstRow    : Integer; 
  StringGridFirstCol    : Integer; 
  SizeStringGridToFit   : Boolean; {Make the StringGrid the same size as the input range} 
  ClearStringGridFirst  : Boolean  {cells outside input range in StringGrid are cleared} 
  ): Boolean; 
Var 
  C,R : Integer; 
Begin 
  Result := False; 
  If ExcelLastCol < ExcelFirstCol Then Exit; 
  If ExcelLastRow < ExcelFirstRow Then Exit; 
  If (ExcelFirstRow < 1) Or (ExcelFirstRow > 255)   Then Exit; 
  If (ExcelFirstCol < 1) Or (ExcelFirstCol > 30000) Then Exit; 
  If (ExcelLastRow  < 1) Or (ExcelLastRow > 255)    Then Exit; 
  If (ExcelLastCol  < 1) Or (ExcelLastCol > 30000)  Then Exit; 
  If StringGrid = nil   Then Exit; 
  If SizeStringGridToFit Then 
  Begin 
    StringGrid.ColCount := ExcelLastCol - ExcelFirstCol + StringGridFirstCol + 1;
    StringGrid.RowCount := ExcelLastRow - ExcelFirstRow + StringGridFirstRow + 1;
  End; 
  If ClearStringGridFirst Then 
  Begin 
    C := StringGrid.ColCount; 
    R := StringGrid.RowCount; 
    StringGrid.ColCount := 1; 
    StringGrid.RowCount := 1; 
    StringGrid.Cells[0,0] := ''; 
    StringGrid.ColCount := C; 
    StringGrid.RowCount := R; 
  End; 

  Result := True; 
  For R := ExcelFirstRow To ExcelLastRow Do 
  Begin 
    For C := ExcelFirstCol To ExcelLastCol Do 
    Begin 
      Try 
        StringGrid.Cells[ 
          C - ExcelFirstCol + StringGridFirstCol, 
          R - ExcelFirstRow + StringGridFirstRow] := 
            Excel.Cells[R, C]; 
      Except 
        Result := False; 
      End; 
    End; 
  End; 
End;

procedure TForm1.Button1Click(Sender: TObject);
var
  excel: Variant;
begin
 excel := createoleobject('excel.application');
 excel.workbooks.open ('c:\mappe1.xls');
 ExcelCopyToStringGrid(excel, 1, 1, 14, 7, StringGrid1, 0, 0, true, true);
 excel.application.quit;
end;

end.

Vergiss comobj in der uses-clausel nicht!

Gruß und viel Spaß damit

Habe ich ein deja vú? Das haben wir doch erst vor kurzem alles durchgekaut mit dir - oder?
