"unresolved external symbol __sqlResults"
One thing it could be: If functions (sqlepilog, sqlResults, ...) were compiled with C compiler and you want them to use in C++, you need to declare them as extern "C"... Example: Instead of void sqlepilog( void* ); use extern "C" void sqlepilog( void* ); Or make changes in...- hcexi

How do I execute timer and another function at he same time

Can't alloc a two dimensional string array
Believe me, you should not EVER do that. (-: I will try to explain it a bit... Inside of scopes defined by your function you defined a variable. It was ok. OS ( operation system ) knew that there is a memory space for your variable. After your function ended, OS destroys variable and marks that... -
