Thread: Get current selection from combobox

I cannot get the value of the item selected in a combobox.....
whats wrong? is it the integer number? should it be a pointer, an array?
I tried it all but non seems to work

Code:

switch (Message)
    { 
       case WM_COMMAND:
         {
	switch(LOWORD(wParam))
	{
                                           
	  case IDC_CON:
	  { 
                     number = SendMessage(hCombo,CB_GETCURSEL, 0,0); //Global variable
                    
                  }break;
                } 
        }break;
     }
//

Note: it is the first time I am using comboboxes and I have referrenced from MSDN
