Hello friends!.
I created a dll made ​​in C + + to return values ​​that were surveyed in a database SQLITE3!
At first everything works correctly, BUT , when the database starts to earn enough database tables start getting bigger is that my real problem starts! The operation is totally unstable!
Suddenly I get an crash error.
These errors happen when I need to receive the data.
But not always. Sometimes it works fine and others it can generate a crash error, which I can not identify.
But I managed to identify these occasional errors always happen when I use search functions of data. When I need to get a large number data is then subject to severe receiving a crash error.
could you give me tips so I can STABILISE my function?
Sample my DLL and LiteC Script:
C++
//Receive data from rows and columns of the DataBase
...
DLLFUNC char* sqlite__select(int r, int c)
{
//return char value on rows [r] and Column [c]
return ((char*)result[r][c].c_str());
}
...
LiteC, Receive Many data.
void test_select()
{
int rows = sqlite_rows(); //Total de rows (sample 100 rows)
for(ping = 0; ping < rows; ping ++)
{
//ID
printf("%s",sqlite_select(ping,0)); //return 0..1..2..3..4..n
//test0
printf("%s",sqlite_select(ping,1)); //return 0..1..2..3..4..n
//test1
printf("%s",sqlite_select(ping,3)); //return 0..1..2..3..4..n
.... test100
}
Can happen or not returning a crash error. (T.T)
