Is there any way of either forcing the user to choose a file from Network Neighbourhood, or if they specfiy a file from a mapped drive - to show the full network path.

That is, any file that a user chooses I require in the following format:

\\Machine Name\Dir1\Dir2\File.ext

You could also use ExpandUNCFileName from SysUtils and check if the first two characters of the returned string are \\ (otherwise the file is a local file)

I have not fully tested it...


function UnMap(path: String): String;
var a: array[0..MAX_PATH] of Char;
    drive: String;
    retval : DWORD;
    len : Cardinal;
begin
   Result := path;
   drive := ExtractFileDrive(path);
   Delete(path, 1, length(drive));
   len := sizeof(a);
   retval := WNetGetConnection(PChar(drive), a, len);
   if retval = 0 then
     Result := a + path;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
    Label1.Caption := UnMap(OpenDialog1.FileName)
end;

Use this function ...

function GetAbsoluteFilePath(RefPath: String; var AFilePath: String): Boolean;
var
  R : PChar;
  RS : Cardinal;
begin
  {I assume that you pass the OpenDialog.Filename
  The path is complete ...}
  {You can remove the next 3 lines if you set ofFileMustExists to True and make this a procedure}
  Result := FileExists(RefPath);
  if not Result then
    Exit;
  RS := 256;
  GetMem(R, RS);
  if WNetGetConnection(PChar(Copy(RefPath, 1, 2)), R, RS) = 0 then
    begin
      System.Delete(RefPath, 1, 2);
      AFilePath := StrPas(R) + RefPath;
    end
   else
    AFilePath := RefPath;  
  R := Nil;
  FreeMem(R);
end;
