[100nF]

dann beschreib uns mal, was du geändert hast, damit sich die listboxen leeren lassen. am besten mit code.

[i]vorher

Delphi-Quellcode:

function FindAllFiles(RootFolder: string; Mask: string = '*.*'; Recurse: Boolean 
  = True): TStinDynA; 
var 
//--Funktionsvariablen--------------------------------------------------------------------- 
  Wn32FiDa: TWin32FindData; 
  File0001: THandle; 

begin 
  if AnsiLastChar(RootFolder) <> '\' then 
  begin 
    RootFolder := RootFolder + '\'; 
  end; 
  if Recurse then 
  begin{if-1} 
    File0001 := FindFirstFile(PChar(RootFolder + '*.*'), Wn32FiDa); 
    if File0001 <> INVALID_HANDLE_VALUE then 
    try {try(if-2)} 
      repeat 
      if Wn32FiDa.dwFileAttributes and FILE_ATTRIBUTE_DIRECTORY=FILE_ATTRIBUTE_DIRECTORY then 
      begin 
        if (string(Wn32FiDa.cFileName) <> '.') and (string(Wn32FiDa.cFileName) <> '..')then 
        begin 
          FindAllFiles(RootFolder + Wn32FiDa.cFileName, Mask, Recurse); 
        end; 
      end; 
      until FindNextFile(File0001, Wn32FiDa) = False; 
      finally 
      windows.FindClose(File0001); 
    end;{try(if-2)} 
  end;{if 1} 
  File0001 := FindFirstFile(PChar(RootFolder + '*.*'), Wn32FiDa); 
  if File0001 <> INVALID_HANDLE_VALUE then 
  try {try(if-4)} 
    repeat 
      if Wn32FiDa.dwFileAttributes and FILE_ATTRIBUTE_DIRECTORY <> 
        FILE_ATTRIBUTE_DIRECTORY then 
      begin 
        gFileCont := length(gFile0001)+1; 
        Setlength(gFile0001, gFileCont); 
        gFile0001[gFileCont - 1] := RootFolder + String(Wn32FiDa.cFileName); 
      end;{if-3}

    finally 
    Windows.FindClose(File0001);

Nachher

Delphi-Quellcode:

function FindAllFiles(RootFolder: string; Mask: string = '*.*'; Recurse: Boolean 
  = True): TStinDynA; 
var 
//--Funktionsvariablen--------------------------------------------------------------------- 
  Wn32FiDa: TWin32FindData; 
  File0001: THandle; 

begin
  SetLength(gFile0001, 0); //<= das hab ich eingefügt!!
  if AnsiLastChar(RootFolder) <> '\' then 
  begin 
    RootFolder := RootFolder + '\'; 
  end; 
  if Recurse then 
  begin{if-1} 
    File0001 := FindFirstFile(PChar(RootFolder + '*.*'), Wn32FiDa); 
    if File0001 <> INVALID_HANDLE_VALUE then 
    try {try(if-2)} 
      repeat 
      if Wn32FiDa.dwFileAttributes and FILE_ATTRIBUTE_DIRECTORY=FILE_ATTRIBUTE_DIRECTORY then 
      begin 
        if (string(Wn32FiDa.cFileName) <> '.') and (string(Wn32FiDa.cFileName) <> '..')then 
        begin 
          FindAllFiles(RootFolder + Wn32FiDa.cFileName, Mask, Recurse); 
        end; 
      end; 
      until FindNextFile(File0001, Wn32FiDa) = False; 
      finally 
      windows.FindClose(File0001); 
    end;{try(if-2)} 
  end;{if 1} 
  File0001 := FindFirstFile(PChar(RootFolder + '*.*'), Wn32FiDa); 
  if File0001 <> INVALID_HANDLE_VALUE then 
  try {try(if-4)} 
    repeat 
      if Wn32FiDa.dwFileAttributes and FILE_ATTRIBUTE_DIRECTORY <> 
        FILE_ATTRIBUTE_DIRECTORY then 
      begin 
        gFileCont := length(gFile0001)+1; 
        Setlength(gFile0001, gFileCont); 
        gFile0001[gFileCont - 1] := RootFolder + String(Wn32FiDa.cFileName); 
      end;{if-3}

ich bin so blöd!!
Ich habs falsch eingefügt.


jetzt get's

habs jetzt

Delphi-Quellcode:

procedure TForm1.Btncopy0004Click(Sender: TObject); 
begin
  SetLength(gFile0001, 0); //<= Hier ausprobiert!!  
  LbxCopy0001.Items.clear;        
  LBxCopy0002.Items.clear;      
  EdtCopy0001.Text:=''; 
end;

und auf anhieb klapt's ohne Probleme
