Excel - Export ohne Excel - Problem beim erzeugen

[padavan]

Hallo alzaimar,

ich habe nichts ausgelassen. Da ist der komplette Auschnitt aus dem Programm.
Ich hatte wiegesagt vermutet, dass sich die Deklaration aus dem .asstring ergeben soll....



Hier die Unit:

Delphi-Quellcode:

unit u_ExportEXCEL;

interface
uses classes;

type TXLSExport = class(TObject)
                  private
                     fs : TFilestream;
                  public
                     constructor Create(filename : string);
                     destructor  Destroy; override;
                     procedure Write(const Col, Row: Word; const Value: Integer); overload;
                     procedure Write(const Col, Row: Word; const Value: Double); overload;
                     procedure Write(const Col, Row: Word; const Value: string); overload;
                  end;


implementation

const
  CXlsBof    : array[0..5] of Word = ($809, 8, 00, $10, 1, 0);
  CXlsEof    : array[0..1] of Word = ($0A, 00);
  CXlsLabel  : array[0..5] of Word = ($204, 0, 0, 0, 0, 0);
  CXlsNumber : array[0..4] of Word = ($203, 14, 0, 0, 0);
  CXlsRk     : array[0..4] of Word = ($27E, 10, 0, 0, 0);


constructor TXLSExport.Create(filename : string);
begin
  inherited Create;
  fs := TFileStream.Create(filename,fmCreate);
  fs.WriteBuffer(CXlsBof, SizeOf(CXlsBof));
end;

destructor TXLSExport.Destroy;
begin
  fs.WriteBuffer(CXlsEof, SizeOf(CXlsEof));
  inherited Destroy;
end;

procedure TXLSExport.Write(const Col, Row: Word; const Value: Integer);
var
  V: Integer;
begin
  CXlsRk[2] := Row;
  CXlsRk[3] := Col;
  fs.WriteBuffer(CXlsRk, SizeOf(CXlsRk));
  V := (Value shl 2) or 2;
  fs.WriteBuffer(V, 4);
end;

procedure TXLSExport.Write(const Col, Row: Word; const Value: Double);
begin
  CXlsNumber[2] := Row;
  CXlsNumber[3] := Col;
  fs.WriteBuffer(CXlsNumber, SizeOf(CXlsNumber));
  fs.WriteBuffer(Value, 8);
end;

procedure TXLSExport.Write(const Col, Row: Word; const Value: string);
var L: Word;
begin
  L := Length(Value);
  CXlsLabel[1] := 8 + L;
  CXlsLabel[2] := Row;
  CXlsLabel[3] := Col;
  CXlsLabel[5] := L;
  fs.WriteBuffer(CXlsLabel, SizeOf(CXlsLabel));
  fs.WriteBuffer(Pointer(Value)^, L);
end;

end.

Vielleicht kannst du dir nun einen Reim drauf machen ?!?!
