problem with DAO in VC 5.0
Hello,
I've the following problem in Visual C++ 5.0:
My source file is:
"#include <dbdao.h>
#include <dbdaoerr.h>
CdbDBEngine dbeng;
CdbDatabase db;
CdbRecordset rstMio, rstTemp;
int nRS, nFld;
void main()
{
db = dbeng.OpenDatabase(_T("pippo.mdb"));
rstMio = db.OpenRecordset("Tabella1", dbOpenSnapshot);
...
db.Close();
Quote:
};
"
When I compile the sorce I haven't problem but when I make the executable
the linker give me these error messages:

Thanx for answer!

PS: I've installed the daosdk 3.5 and in directory section of the linker
I've specifed the right position of dao headers and libraries
