![]() |
Text von Res (Resource Datei) in Lazarus-Projekt laden, Filestream leer [gelöst]
Hallo, diese Anleitung
![]() Allerdings ist der Filestream immer leer wenn ich ihn eingelesen habe. (Wenn ich direkt mit dem Debugger reingehe meine ich, klar ist das er bei finally ja wieder freigeben wird.) Es kommt kein Compilerfehler. Hier der Code:
Delphi-Quellcode:
program project1;
{$mode objfpc}{$H+} uses {$IFDEF UNIX}{$IFDEF UseCThreads} cthreads, {$ENDIF}{$ENDIF} Interfaces, // this includes the LCL widgetset Forms, Unit1 { you can add units after this }, Classes, SysUtils, FileUtil, Controls, Graphics, Dialogs, StdCtrls, Windows; //{$R *.res} {$R xId.res} var S: TResourceStream; F: TFileStream; StrList:TStringList; begin // create a resource stream which points to our resource S := TResourceStream.Create(HInstance, 'XID', RT_RCDATA); // Please be aware of writing an apostrophes in resource type - source will not be axtracted!!! try // create a file mydata.dat in the application directory F := TFileStream.Create(ExtractFilePath(ParamStr(0)) + 'xId.txt', fmCreate); StrList := TStringList.Create; try F.CopyFrom(S, S.Size); // copy data from the resource stream to file stream StrList.LoadFromStream(F); finally F.Free; // destroy the file stream StrList.Free; end; finally S.Free; // destroy the resource stream end; RequireDerivedFormResource := True; Application.Initialize; Application.CreateForm(TForm1, Form1); Application.Run; end. |
AW: Text von Res (Resource Datei) in Lazarus-Projekt laden, Filestream bleibt leer
Ok ich habs hinbekommen, allerdings etwas anders. Mit dem F.CopyFrom(S, S.Size); scheint irgendwas schief zu gehen. Aber so wie unten gehts.
Delphi-Quellcode:
unit Unit1;
{$mode objfpc}{$H+} interface uses Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls,Windows; type { TForm1 } TForm1 = class(TForm) Button2: TButton; Memo1: TMemo; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); private { private declarations } public { public declarations } end; var Form1: TForm1; implementation {$R *.lfm} {$R xId.res} { TForm1 } procedure TForm1.Button2Click(Sender: TObject); var rs: TResourceStream; begin rs := TResourceStream.Create(hinstance, 'XID', RT_RCDATA); try Memo1.Lines.LoadFromStream(rs); finally rs.Free; end; end; end. |
