Hello all,

I have a TIdHTTPServer and in the Connect event i do like this
		dataptr = new TServDataObj(this);
		dataptr->OnIoInfo = IoInfoEvent;
		AThread->Data = dataptr;

in the IdHTTPServerCommandGet like this
	TServDataObj *dataptr;

		dataptr = (TServDataObj*)AThread->Data;
		dataptr->xmlVal = RequestInfo->Params->Values["trans"];
		if ( dataptr->xmlVal.Length() > 10 ) {
			dataptr->Exequte();
			ResponseInfo->ContentStream = new 					 
TStringStream(dataptr->sResponse);
			ResponseInfo->ContentStream->Write("OK", 2 );
		}



and in the dataptr i do this

typedef void __fastcall (__closure *TIoInfoEvent)(System::TObject* Sender,
AnsiString &Msg, AnsiString &Seqno, AnsiString &sReturnInfo, AnsiString 
&sTextid, int &seq);


__fastcall TServDataObj::TServDataObj(TObject* Sender)
{

}
void __fastcall TServDataObj::Exequte()
{
	//call a function and fire the event OnIoInfo
}

if ( FOnIoInfo && SDiDspTxt.Length() ) {
	OnIoInfo(this, SDiDspTxt, seqno, sReturnInfo, sTxtId, F_localseqno);

the problem is that in the Taskmanager i can se that the handles is 
increase every time i fire the event, why?

Make sure you free the TServObj object in the OnDisconnect event.

> in the IdHTTPServerCommandGet like this

Are you setting a response if the request data is less than 10 characters?

> TStringStream(dataptr->sResponse);

You don't need to wrap the Response string into a TStringStream.
TIdHTTPResponseInfo has a ContentText property that you can use instead:

    ResponseInfo->ContentText = dataptr->sResponse;

> ResponseInfo->ContentStream->Write("OK", 2 );

Why are you appending an OK to the end of the response data?

I don't see you freeing anything.  But then again, the code you showed is
incompletely to begin with.  You didn't even show what your event handler is
actually doing.

I free the TServObj in the OnDisconnect.
Yes I sett a response if less thar 10 character.
I have remove the stream an use the ContentText instead.

My event is as follow

void __fastcall TaxSOChipPinPadImpl::IoInfoEvent(TObject *Sender, 
AnsiString &sMsg, AnsiString &Seqno,	AnsiString &sReturnInfo, 
         					AnsiString &sTextid, int &seq)
{
	//I take care of the sMag, Seqno, ReturnInfo, Textid and the seq
	//and some is stored in local variables
	and calling a function in the mainthread.
}

Can you please show the actual code?

That does not answer my earlier question at all.  You say that the event
handler is increasing handles every time it is triggered, but you have not
yet shown what you are asking doing in the code to begin with.  Noone can
diagnose the problem for you without those kinds of details.
