listbox count???

[computerwhiz]

I am trying to find the count of items in my listbox and then delete those items but when I retrieve the count I get half of what I should. I have tried both ways of getting the listbox count.

example:

my listbox has 10 entries, the count would come back as 5.
my listbox has 3 entries, the count would come back as 2.

case IDC_BUTTON3:
{
  //UINT cnt = SendMessage(hwndLB,(UINT) LB_GETCOUNT, 0, 0);
  DWORD cnt = GetListBoxInfo(hwndLB);
  for(int a = 0; a <= cnt-1; a++)
  {
    SendMessage(hwndLB, LB_DELETESTRING, a, 0);
  }
  break;
}

Don't foregt, when a is incrementing and deleting, the number of items changes, and when a is greater than a half, you already overun the number of items

So unsetad of
SendMessage(hwndLB, LB_DELETESTRING, a, 0);
use
SendMessage(hwndLB, LB_DELETESTRING, 0, 0);
