FindFirst (Delphi)

Description

The following example uses an edit control, a button, a string grid, and seven check boxes. The check boxes correspond to the seven possible file attributes. When the button is clicked, the path specified in the edit control is searched for files matching the checked file attributes. The names and sizes of the matching files are inserted into the string grid. The Path constant parameter is the directory and file name mask, including wildcard characters. For example, '.\test\*.*' specifies all files in the current directory. Click at least one box before clicking the button.

Code

procedure TForm1.Button1Click(Sender: TObject);
var
  sr: TSearchRec;
  FileAttrs: Integer;
begin
  StringGrid1.RowCount := 1;
  if CheckBox1.Checked then
    FileAttrs := faReadOnly
  else
    FileAttrs := 0;
  if CheckBox2.Checked then
    FileAttrs := FileAttrs + faHidden;
  if CheckBox3.Checked then
    FileAttrs := FileAttrs + faSysFile;
  if CheckBox4.Checked then
    FileAttrs := FileAttrs + faVolumeID;
  if CheckBox5.Checked then
    FileAttrs := FileAttrs + faDirectory;
  if CheckBox6.Checked then
    FileAttrs := FileAttrs + faArchive;
  if CheckBox7.Checked then
    FileAttrs := FileAttrs + faAnyFile;
  with StringGrid1 do
  begin
    RowCount := 0;
    if SysUtils.FindFirst(Edit1.Text, FileAttrs, sr) = 0 then
    begin
      repeat
        if (sr.Attr and FileAttrs) = sr.Attr then
        begin
        RowCount := RowCount + 1;
        Cells[1,RowCount-1] := sr.Name;
        Cells[2,RowCount-1] := IntToStr(sr.Size);
        end;
      until FindNext(sr) <> 0;
      FindClose(sr);
    end;
  end;
end;
