I have an application that copies files from the origional directory to a backup/copy directory with a tProgress bar and 2 tLabels to show the progress of the copy
If the user clicks on the program or the windows screen NOT RESPONDING show on the top of the application and the tprogress bar and tlabels stop showing the progress - the program is still running but the user thinks its stopped and exits it. causing the copy not to be completed

How do I stop the the not responding and keep the tProgress bar and tlabels working

attached is a part of the code I am using
for i := 0 to filelistbox.Items.Count - 1 do begin             // Listbox with the files to bg copied
      pbBuild.stepit;                                                          // tProgress Bar
      f := 'c:\backupfiles\' + filelistbox.Items.Strings[i];    
      f1 := 'c:\origionalfiles\' + filelistbox.Items.Strings[i];         
      Label1.caption := 'From  ' + f;
      Label2.caption := 'To  ' + f1;
      Label1.refresh;
      Label2.refresh;
      form1.Refresh;
      CopyFile(PChar(f), PChar(f1), False);
      appscount := appscount + 1;
      form1.bringtofront;
      lCopied.Caption := 'Files Copied - ' + inttostr(AppsCount);
      lCopied.repaint;
      form1.Repaint;
      form1.refresh;
  end;

Try throwing in Application.ProcessMessages - just a guess :p

you can use this

Procedure CopyFiles;
var
i : integer;
begin
for i := 0 to filelistbox.Items.Count - 1 do begin             // Listbox with the files to bg copied
      pbBuild.stepit;                                                          // tProgress Bar
      f := 'c:\backupfiles\' + form1.filelistbox.Items.Strings[i];    
      f1 := 'c:\origionalfiles\' + form1.filelistbox.Items.Strings[i];         
      form1.Label1.caption := 'From  ' + f;
      form1.Label2.caption := 'To  ' + f1;
      form1.Label1.refresh;
      form1.Label2.refresh;
      form1.Refresh;
      CopyFile(PChar(f), PChar(f1), False);
      appscount := appscount + 1;
      form1.bringtofront;
      form1.lCopied.Caption := 'Files Copied - ' + inttostr(AppsCount);
      form1.lCopied.repaint;
      form1.Repaint;
      form1.refresh;
  end;
 
procedure TForm1.Button1Click(Sender: TObject);
var
id : cardinal;
begin
 BeginThread(nil,0,@CopyFiles,nil,0,ID);
end;

ps: specify in all components used in the procedure "CopyFile"  Form1.  before.(ex: like i forget fist[Form1.filelistbox.Items.Count...])
