Hi all,

I have a little FTP server with Indy 9 components. When user connects (e.g. 
Total Commander), then disconnects, connects, disconnects...  sometimes I 
get Windows Blue Screen of Dead :-( . This is the smallest code, when this 
error still appears:

//---------------------------------------------------------------------------

void __fastcall TFormMain::FormCreate(TObject *Sender)
{
  ButtonStart->Enabled=true;
  ButtonStop->Enabled=false;
}

void __fastcall TFormMain::ButtonStartClick(TObject *Sender)
{
  FTPServer->Active=true;
  ButtonStart->Enabled=!FTPServer->Active;
  ButtonStop->Enabled=FTPServer->Active;
}

void __fastcall TFormMain::ButtonStopClick(TObject *Sender)
{
  FTPServer->Active=false;
  ButtonStart->Enabled=!FTPServer->Active;
  ButtonStop->Enabled=FTPServer->Active;
}

void __fastcall TFormMain::FTPServerListDirectory(TIdFTPServerThread 
*ASender,
      const AnsiString APath, TIdFTPListItems *ADirectoryListing)
{
  TIdFTPListItem        *LFTPItem;

  ADirectoryListing->ListFormat=flfUnix;
  ADirectoryListing->DirectoryName=APath;
  LFTPItem=ADirectoryListing->Add();
  LFTPItem->FileName="test.txt";
  LFTPItem->Size=100;
  LFTPItem->ItemType=ditFile;
  LFTPItem->ModifiedDate=Now();
  LFTPItem->OwnerName="anonymous";
  LFTPItem->GroupName="all";
  LFTPItem->OwnerPermissions="rw-";
  LFTPItem->GroupPermissions="rw-";
  LFTPItem->UserPermissions ="rw-";
}

//---------------------------------------------------------------------------

What I am doing wrong? Error appears only on non-NT platforms (98, Me).

Have you tried using a different FTP app ?

And, BTW, this should not fix your problem, but you should not be using 
OnCreate. It is a Delphi remnant that is illegal in C++, because it can 
call the function before the constructor is called. Rather just set those 
two button states in the Object Inspector.

I tried Cerberus FTP Server, it works fine, without any BSoD. Then I stop 
it, run my tiny FTP server, make 3-times connect-disconnect and BSoD 
appears. For connection I used Total Commander and Internet Explorer with 
the same result. Using MSIE BSoD appears when window is closed (connection 
closed).

OT:
I thought that OnCreate event is called after initialization of all 
components is finished. Where can I call initialization section of my 
program (reading Registry, setting memory structures, ...) ?

In applications developed with c++builder OnCreate can sometimes
be called even before the constructor.

Place that code in the constructor.

Hi,

I'd rather place it on the OnShow event where it is secure that
all components are already created.
