<-------------------------------->

WinExec32('c:\windows\explorer.exe',0);

<-------------------------------->

function WinExec32(Filename:string; Visibility:integer) : integer;
var zAppName: array[0..512] of char;
    zCurDir : array[0..255] of char;
    Workdir : string;
    StartUpInfo : TStartUpInfo;
    ProcessInfo : TProcessInformation;
begin
  StrPCopy(zAppName,FileName);
  GetDir(0,Workdir);
  StrPCopy(zCurDir,Workdir);
  FillChar(StartUpInfo,SizeOf(StartUpInfo),#0);
  StartUpInfo.cb := SizeOf(StartUpInfo);
  StartUpInfo.dwFlags := STARTF_USESHOWWINDOW;
  StartUpInfo.wShowWindow := Visibility;

  if not CreateProcess(nil,zAppName,nil,nil,false,
                       CREATE_NEW_CONSOLE or
                       NORMAL_PRIORITY_CLASS,
                       nil,nil,StartUpInfo,
                       ProcessInfo) then
    Result := -1
  else
    begin
//      WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
      GetExitCodeProcess(ProcessInfo.hProcess,Result);
    end;
end;

ItsMe, cono's answer won't help you.
You must do this:
(1) Set "shell=Explorer.Exe"
(2) Start Explorer.exe
(3) Wait, until it is completely started
(3) Set "shell=C:\YourPath\YourProgram.exe"

Madshi,
I want to write a login software which starts the explorer when
the login was correct. It wouldn't help me to start the explorer
first because nobody is allowed to access it during the time
my program is running. My program will change different system
settings after login and then starts explorer.exe but explorer
starts as fileman I guess there is a parameter ? Or must I only change the system.ini entry to explorer.exe before I start it ?

You got it. That's what I tried to tell you with my last comment.

why this code does not work ?

procedure TForm1.Button1Click(Sender: TObject);
begin
  WritePrivateProfileString('boot','shell','explorer.exe','system.ini');  // flush ini
  WritePrivateProfileString(nil,nil,nil,'system.ini');  // flush ini
  shellexecute(0,nil,'explorer.exe',nil,nil,sw_show);
//  WritePrivateProfileString('boot','shell','myshell.exe','system.ini');  // flush ini
end;

hi silvamv,
perhaps you should give the whole path to shellexecute ? btw. what exactly doesn't work / what happens ?

MadshiCommented:
It should work without the path. But you need to wait until the explorer is fully loaded before you switch the shell setting back. Use one of this possibilities:

(1) Use CreateProcess instead of ShellExecute, then WaitForInputIdle(processInfo.hProcess). And don't forget to close the handles afterwards.
(2) Wait until the tray window is visible (IsWindowVisible(FindWindow('Shell_TrayWnd', ''));).

Regards, Madshi.

Madshi, could you give a sample ? How I use CreateProcess to do it ?
Thank's a lot.

Oh no, please. Can't you figure that out yourself? If not, please ask a new question. Look, this question had only 10 points. Now you want even additional help from me for the same 10 points I got from ItsMe...
