Hi,
Sherief, thank you for our kind help.
I really did use globals.
I found a way to run DumpMemorLeaks after all globals and static
variables are deallocated, I used
_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
I made some malloc and new leaks around the code I'm interested in

I really don't see any way to use _CrtDumpMemoryLeaks(). It always
shows hundreds of blocks even if I'm sure that nothing was allocated
(no malloc or new). I know that this is not a place to learn how

SQLite also does some "interesting"
I figured up, that in my main app, when I don't make nested queries no
memory leaks. In simple app no matter id I use nested or strait
queries memory does not leak.
For example:
sprintf( lpbuf, "SELECT tagList FROM overlay WHERE modalityID=%d "
"AND
Hi,
I have written simple app that does the same query on the same
database and I have no memory leaks !?!
I build two apps with similar options (f.e. multithreaded debug dll)
but my main app is written in winapi and "simple" app as console app.
I have really no idea what can make these two act

Hi,
In my C++ application I'm writing/reading some blob data to the
database. This is sample of my code (in 99% taken from example i found
in the internet ):
/**
* This function reads one blob value asqued in zSql query into memory
pointed by pzBlob
* and returns size of allocated memory in
10 matches
