Resource Leak using dynamicarray

[BE]

Hi,

I have a project that uses DynamicArray to pass array to Chartseries in BCB2007. with CodeGard turned on, I've been getting resource Leak msgs. So I build the following sample case. Sure enough. There's a resource leak msg.


#ifndef Unit1H
#define Unit1H
//---------------------------------------------------------------------------
#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include "Chart.hpp"
#include "Series.hpp"
#include "TeEngine.hpp"
#include "TeeProcs.hpp"
#include <ExtCtrls.hpp>
#include <Buttons.hpp>
//---------------------------------------------------------------------------

typedef DynamicArray < double > TDARRAY;


class TForm1 : public TForm
{
__published: // IDE-managed Components
TChart *Chart1;
TPanel *Panel1;
TBitBtn *BitBtn1;
TFastLineSeries *Series1;
void __fastcall BitBtn1Click(TObject *Sender);
private: // User declarations

TDARRAY DataX;
TDARRAY DataY;

public: // User declarations
__fastcall TForm1(TComponent* Owner);
};
//---------------------------------------------------------------------------
extern PACKAGE TForm1 *Form1;
//---------------------------------------------------------------------------
#endif


// .cpp code

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

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma link "Chart"
#pragma link "Series"
#pragma link "TeEngine"
#pragma link "TeeProcs"
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------
void __fastcall TForm1::BitBtn1Click(TObject *Sender)
{
DataX.Length = 101;
DataY.Length = 101;

for(int i = 0; i < DataX.Length; i++)
{
DataX = i * 0.5;
DataY = i * i * 0.5;
}

Series1->XValues->Value = DataX;
Series1->XValues->Count = DataX.Length;
Series1->XValues->Modified = 1;
Series1->YValues->Value = DataY;
Series1->YValues->Count = DataY.Length;
Series1->YValues->Modified = 1;

}
//---------------------------------------------------------------------------

When I run this program with CodeGard on, I'll get Resource Leak after closing the program.

Where is the leak coming from?

I'm using TChart Pro v7.12 win32.

Hi Bill,

have you tried to add a FreeAllSeries in the OnClose event ? :

Chart.FreeAllSeries;

[BE]

I'll give that a try.

Thanks
