I want to have filtered TOpenDialog filelist matching to preset filename mask.
E.g.
 OpenDialog.Filename := filepath + 'MyDocs*' +'*.doc';
 OpenDialog.Execute;
...
Only files named initial as "MyDocs..." would be visible in the OpenDialog filelist?
 
How to do?

You can add in design mode or in code this property:
  OpenDialog1.Filter := 'Document files (*.doc)|*.doc';
  OpenDialog1.DefaultExt := '.doc';

Open in new window


... property FileName is for setting destination/source file.

This filter have affect only to file extensions, not names.
I want to show filenames, e.g. all files witch match to "MyDoc*.doc'.  (MyDoc1, MyDoc2, MyDoc3,etc).

Have tried something as below:

ListFiles(prg.FilePath, 'MyDoc*.doc', OpenDialog1.Files);
// This does not update files in the OpenDialog....

procedure ListFiles(const AFolder, AFilter: string; AList: TStrings);
var
  vFindHandle: THandle;
  vFilter    : String;
  vFindData  : WIN32_FIND_DATA;
begin
  AList.BeginUpdate;
  try
    AList.Clear;
    vFilter := AFolder + '\' + AFilter;
    vFindHandle := FindFirstFile(PChar(vFilter), vFindData);
    if vFindHandle = INVALID_HANDLE_VALUE then  Exit;
    repeat
      AList.Add(ChangeFileExt(vFindData.cFileName, ''));
    until not FindNextFile(vFindHandle, vFindData);
    Windows.FindClose(vFindHandle);
  finally
    AList.EndUpdate;
  end;
end;

Then it should be:
OpenDialog1.Filter := 'MyDoc files (MyDoc*.doc)|MyDoc*.doc';

Open in new window

Ok, I agree this works as is... but I have to use a variabel to identify users and allow select  only respective users files

us := usr.LoggedUser;

OpenDialog1.Filter := us + ' logs ('+ us + '*.log)|us + *.log';

Seems good, but a still a little problem... This does not work :-(
(Hardcoded  filter does work fine)

Found it ...
  us := usr.LoggedUser;
  flt := 'Logfiles (' + us + '*.log)|' + us + '*.log';
  OpenDialog1.Filter := flt;

Thanks!
