Hi again Robert,
I think i forgot to tell you that to detect the memory leak you must not close
the application testing program, the easiest way to detect the memory leak is:
create a simple MFC dialog project. Add 2 buttons, one for executing your
testing program an another one for close the application from it.
If you execute your testing program and you monitorize the memory usage with
the Remote performance monitor (from the tools menu at the EVC 4.0
IDE->tools->Remote Performance Monitor->Select your device->press
the sign (add)->change combo Box selection to Memory->add a graphic
line for memory load). You will notice that memory is only recovered once you
execute the button to close the application.
I hope this might help you.
Thank you,
Eduardo

Hi Robert,
Thank you for your test. I have not test it on the emulator but in 4 di
fferent Windows CE devices i have at work (with different Windows CE OS
versions) and it always give me the same memory leak result.
I will run your test tomorrow at work using the emulator and i will l
et you know the results.
Thank you again,
Eduardo
---Mensaje original---Ok, here's what I did ...
On the desktop I created a SQLite database with one table and inserted
120,000 rows into it. I then copied it over to the CE emulator.
Then I ran the following code on the CE (Pocket PC 2003 SE) emulator:
#include
#include
#include "sqlite3.h"
int WINAPI _tWinMain(HINSTANCE hInst, HINSTANCE hPrev, LPTSTR pszCmdLin
e,
int nCmdShow)
{
sqlite3 *pdb;
int rc;
for (int n = 0; n < 10000; n )
{
rc = sqlite3_open("\\test.db3", &pdb);
if (rc) break;
rc = sqlite3_exec(pdb, "select * from testcase", 0, 0, 0);
if (rc) break;
rc = sqlite3_close(pdb);
if (rc) break;
}
return 0;
}
On the first call to sqlite3_exec(), available program memory dropped f
rom
an initial 10.5mb to 8.45mb. However, once that was done, available mem
ory
remained rock solid for the duration of the loop at a constant 8.45mb a
nd no
non-zero error codes were ever returned.
