Problem out of memory

Hi,

I'm working on Pocket PC 2002 and have an application which is displaying a
message : "Out of memory".
That's the os which is displaying this message.

I want just to know if someone has an idea of that problem ?
I think that the problem comes from a procedure in the program : the
application is calling every second a dll which in order to display the life
time percent of battery.

Thanks for any information about that problem.

The problem is likely that the device is running out of memory, just like it
says. If you have something happening periodically (like you suggest) then
it's definitely a candidate for the leak, but without you posting your code,
we can't very well diagnose the bug.

Do you have a Toshiba e740? This seems to be a common problem for this
model. I get these error messages quite often. In my case the only
solution is to close all other programs.

Hi,

First one, I'm using an Intermec 760 Color PDA.

Concering the code, I can only show you the code of the dll which is written
in C++.
In fact, the other part of code is generated by an AGL and it's not easy to
show you that code.

The main program is calling a dll every 20 seconds. The code is the
following :
----------------------------------------------------------------------------------------------
#include "stdafx.h"
#include "Winbase.h"
#include "tchar.h"
#pragma comment(lib, "coredll.lib")

TCHAR a_szSUC[] = _T("1");
TCHAR a_szERR[] = _T("0");

BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved)
{
return TRUE;
}

int GetInfosBatt()
{
SYSTEM_POWER_STATUS_EX powerStatusEx;
int nBattValue = 0;

BOOL fRet = GetSystemPowerStatusEx(&powerStatusEx, true);
if(fRet)
{
nBattValue = powerStatusEx.BatteryLifePercent;
return nBattValue;
}
return -1;
}

int GetFlagBatt()
{
SYSTEM_POWER_STATUS_EX powerStatusEx1;
int nFlagBatt = 0;

BOOL fRet = GetSystemPowerStatusEx(&powerStatusEx1, true);
if(fRet)
{
nFlagBatt = powerStatusEx1.BatteryFlag;
return nFlagBatt;
}
return -1;
}

extern "C" void GetBattInfos(TCHAR** pData)
{
int flagVal = 0;
int flagBatt = 0;
LPTSTR str1 = _T("");
LPTSTR str2 = _T("");
char buffer1[3];
char buffer2[3];

flagVal = GetInfosBatt();
flagBatt = GetFlagBatt();

if(flagVal != -1 && flagBatt != -1)
{
pData[2] = a_szSUC;
}
else
pData[2] = a_szERR;

_itoa(flagVal, buffer1, 10);
int size1 = MultiByteToWideChar(CP_ACP, 0, buffer1, -1, NULL, 0);
MultiByteToWideChar(CP_ACP, 0, buffer1, -1, str1, size1);
pData[0] = str1;

_itoa(flagBatt, buffer2, 10);
int size2 = MultiByteToWideChar(CP_ACP, 0, buffer2, -1, NULL, 0);
MultiByteToWideChar(CP_ACP, 0, buffer2, -1, str2, size2);
pData[1] = str2;
}
-----------------------------------------------------------------------------------------------

So I'm using an "execute" function every 20 seconds. That function is
calling the "GetBattInfos" external function every 20 seconds, but what does
that function ? Is the dll loaded in memory every time ?

Thanks for any information.
