When I am writing a puzzle game and its size can be made from 2 to 5:

e.g. the index number of h is (1, 1)

| H | G | E |
| F | h | C |
| D | B | A |

or the index number of h is (3, 3)

| D | A | K | F |
| G | I | N | J |
| B | E | H | O |
| M | L | C | h |

since the elements and the hole(h) are randomly generated, it means I dont know the exact location of the hole(h), how can I use the suggestion you gave me for swapping?

Yeah you are right this time. h is at (3,3)

You have to loop through and find out where h is?

Again, since I dont know the size of the puzzle, how do I know the index number of the target element for swapping, at this moment I know the index number of h is (hrow, hcol)?

Am I wrong if I think this way?

e.g.

C | B
A | h

Assume the location of h at the keyboard is always on 5, then I hit 4 to swap h with A, hit 8 to swap B with h, and hit 7 to swap C with h.

For swapping A
tar_row = hrow;
tar_col = --hcol;

For swapping B
tar_row = --hrow;
tar_col = hcol;

For swapping C
tar_row = --hrow;
tar_col = --hcol;

Am I wrong?

Check out SetWindowText[^] method. You'll probably need something like:

CWnd * pWnd = NULL;
pWnd = GetDlgItem( BUTTON_ID );
if( pWnd == NULL )
{ // Button not found
	_ASSERT( FALSE );
}
else
{
	pWnd->SetWindowText( TEXT( "Good" ) );
}

How can one disable the Drop in particular when using the IWebBrowser2 control. I am using it in places where it is inappropriate to able to drop a file on it.
Setting the Allowfiles to false seems not to work.

Any suggestions would be appreciated.

Happy programming!!

This library[^] contains a basic Base64 encoder / decoder, thats probably a good starting point to have a look at.

You might always want to have a look the original RFC[^] for reference aswell.
