VC++ win32 API programming :how to change mouse cursor

I am trying to change the mouse cursor and write the code below but doesn't work. It seems IDC_CURSOR_WHITE should be put into a rc file. I tried and failed. At last I came here seeking your guidance. Help! Thanks.

IDC_CURSOR_WHITE IDC_CURSOR_BLACK not

hWhiteCursor = ::LoadCursor(hInstance, (LPCTSTR)IDC_CURSOR_WHITE);

hBlackCursor = ::LoadCursor(hInstance, (LPCTSTR)IDC_CURSOR_BLACK);



case WM_LBUTTONDOWN:
  if ((type = ++type % 2) == 0)
   SetCursor(hWhiteCursor);
  else 
   SetCursor(hBlackCursor);
  break;
 case WM_SETCURSOR
  return 0;

PS: The rc file code. And the error is mouse cousor not defined.

From the snippets you posted, in the code you are loading the cursors using IDC_CURSOR_WHITE and IRC_CURSOR_BLACK, but you are including them in the .rc file as IDC_CURSOR1 and IDC_CURSOR2.

This is what I do when I need to use resources. First I create a resource.h file and define the Resource Name with a unique integer. Include resource.h file in your .rc file and then define the actual resource. So in your case the files should be as follows

resource.h
#define IDC_BLACK_CURSOR   1001

resource.rc
#include "resource.h"
......
IDC_BLACK_CURSOR CURSOR "cursor1.cur"

Now to use the resource in a particular file, I just include the resource.h file and use the particular cursor. So again in your case, if you want to use the cursor in test.cpp file.

test.cpp
#include "resource.h"
....
hBlackCursor = LoadCursor(hInst, MAKEINTRESOURCE(IDC_BLACK_CURSOR));
.....

I hope this helps. For further information MSDN is always your friend.
