How to mimic this log\feedback behaviour?

Hi my dear friends!

I'm creating this app which empties IE cache. Now I want this app to count files and directories and summarize this along with the amount of MB's of space it occupies, prior to emptying.
Then when emptying it should give feedback about this and afterwards give feedback whether it succeeded.

Now I saw this behaviour in a program I used for creating unattended installs. It also displayed an icon right before every line. Kinda like this:

[icon] [time] Calculating directories: 120 Done!
[icon] [time] Calculating files: 257 Done!
[icon] [time] Calculating space occupied: 200 MB Done!
[icon] [time] Deleting all files and directories....Done!

Something like this.

Regards Paul

Ps thanks in advance, working samples do the trick ofcourse :) This is my code so far. Nothing implemented yet other than the emptying of the cache.

//Code

function TForm1.UserName: String;
var  dwSize:        DWORD;
begin

  // Buffer size to use
  dwSize:=256;

  // Allocate result buffer
  SetLength(result, 256);

  // Get user name
  if GetUserName(Pointer(result), dwSize) then
     // Truncate to actual result
     SetLength(result, Pred(dwSize))
  else
     // Truncate to null string
     SetLength(result, 0);

end;

function DeleteExclude(Path: String; ExcludeFile: String): Boolean;
var  lpFileOp:      TSHFileOpStruct;
     srFind:        TSearchRec;
     dwFind:        Integer;
     szPath:        String;
     szList:        String;
begin

  // Set default delete list
  SetLength(szList, 0);

  // Make sure path is correct
  szPath:=ExcludeTrailingBackSlash(Path);

  // Init the find
  dwFind:=FindFirst(szPath+'\*.*', faAnyFile, srFind);

  // Check find
  if (dwFind = 0) then
  begin
     // Resource protection
     try
        // While sucess
        while (dwFind = 0) do
        begin
           // Check name
           if ((Length(srFind.Name) > 0) and not(srFind.Name[1] = '.')) then
           begin
              // Compare against exclusion
              if (CompareText(srFind.Name, ExtractFileName(ExcludeFile)) <> 0) then
              begin
                 // Add to list
                 szList:=szList+szPath+'\'+srFind.Name+#0;
              end;
           end;
           // Find next
           dwFind:=FindNext(srFind);
        end;
     finally
        // Close the find
        FindClose(srFind);
     end;
  end;

  // Check the list
  if (Length(szList) > 0) then
  begin
     // Double null terminate the list
     szList:=szList+#0;
     // Clear struct
     FillChar(lpFileOp, SizeOf(lpFileOp), 0);
     // Set params
     lpFileOp.Wnd:=Application.Handle;
     lpFileOp.wFunc:=FO_DELETE;
     lpFileOp.pFrom:=PChar(szList);
     lpFileOp.pTo:=nil;
     // Remove the FOF_ALLOWUNDO if you don't want this to go in the recycle bin
     lpFileOp.fFlags:=FOF_SILENT or FOF_NOCONFIRMATION or FOF_ALLOWUNDO;
     // Perform the delete
     if (SHFileOperation(lpFileOp) = 0) and (lpFileOp.fAnyOperationsAborted = False) then
        // Success
        result:=True
     else
        // Failure
        result:=False;
  end
  else
     // Nothing to delete
     result:=True;

end;

procedure TForm1.Btn1Click(Sender: TObject);
begin

  if DeleteExclude('c:\documents and settings\'+UserName+'\local settings\temporary internet files\content.ie5', 'index.dat') then
     ShowMessage('Success')
  else
     ShowMessage('Failure');

end;



end.

// End of code

Tnx to esoftbg, inthe and rlibby for the above piece of code!
