vb.net - Unrecognised database format exception -


i have connect programs database.
edit database in access, , after when running program, error notice unrecognised database format.

then try make new database , connect vb.net failed again.
don't know fault because didn't change in code.
use provider microsoft.ace.oledb.12.0 , file extension in .accdb format.

first possibility: database might have been corrupted. try compact , repair.

second possibility: inadvertently database format changed, if case can "save as" lower version 2003 or 2010.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
