Could anyone tell me if i'm using this right please..



I get an access violation when it runs... i know its those lines because if i comment it out then everythings fine. I did have a go at loadlibrary and getprocaddress, i tried copying the example from msdn and changing it to suit my needs but i couldn't get it to work.. handles, pointers .etc can be a bit confusing for noobs

I'll keep at it tho.

Thanks but doesn't work... i get ;

Which is why i was using (LPCWSTR)...looks like it should work.. but like i said.. if i comment it out everything is ok.. and my program isn't that big at all, yet so i doubt its anything else thats causing this problem.

It said something about writeprivateprofilestring returning a bool value.. so i tried

bool a;

a=dbcalldll(blahblah .etc

but it didn't work.
