Load Cursor from Resource in Win 95

I am trying to load a cursor from a resource - it works in nt but not in 95. here is what I am doing

HCURSOR hCursor,hOldCursor

hCursor = ::LoadCursor(hInst,MAKEINTRESOURCE(IDC_HAND));
hOldCursor = SetCursor(hCursor);

I have also tried
hCursor = ::LoadCursor(hinst,(LPCTSTR)IDC_HAND);
hOldCursor = SetCursor(hCursor);

also tried -
hCursor = (HCURSOR)LoadImage(hInst,MAKEINTRESOURCE(IDC_HAND),IMAGE_CURSOR,0,0,NULL);
hOldCursor = SetCursor(hCursor);

Sorry I want to add - when the LoadCursor command returns it returns NULL which causes the SetCursor(NULL) statement to execute - so the cursor disappears.

First of all IDC_HAND is only available on NT.  2nd of all if you se these constants, the HINSTANCE parameter should be NULL.


Let me know if you have questons.

Actually, to be more precise, the IDC_HAND is available only on NT 5 and later.

Sorry - I mislead you.  I defined a resource called IDC_HAND - I didnt intend to use a system defined one.

Better rename that ID.  You will regret using it in the future!

Hi !
Did you check that you can edit the Cursor usign msvc++4.0 cursor editor ??
I suspect your cursor corrupted.
If not, did you tried create new workspace of project and add the c,resource, cursor into it and recompile again ??

BTW, I tried custom cursor on Win95 platform. It works fine.
Probably you can let me know your e-mail add so that I can mail you the example that I'd created.
Hope that it'll solve your problem.

Are we 100% certain that the hInst parameter to the call is correct? And what is the numerical value of IDC_HAND?

nietodCommented:
Since it is working under NT, it probably isn't a simple problem like that (or even a corrupted cursor.)

I know the cursor is not corrupt and I've checked the hInst variable - thats not the problem.... I can load a cursor from a file and it will work on both machines... It seems like win95 cannot or doesn't get the correct resource id ?? I have looked at the executable to make sure the cursor is a resource in the exe..

Did you check to se what GetLastError() was returning?

gpaigeAuthor Commented:
The last error says that the command succeeded...
What I did was call get GetLastError() if hCursor == NULL..

BigRatCommented:
Nietod's first answer is probably the correct one. If you have the include files the wrong way round you're going to get the wrong constant. That is why I asked what the value of the constant was. Secondly have you tried changing the name like Nietod suggested? If you change the name to say IDC_NIETOD or IDC_RAT in both the defining and referenced places AND ensure that the value of the constant is NOT the same value as that of the system constant, we might get somewhere.

OK I've about had it...
I've changed the resource name to IDC_CURSOR1 I now load it into HCURSOR hMyCursor but no matter what I do hMyCursor is NULL on a Windows 95 machine.  I didn't think changing cursors was so hard.  I also checked the constant value it is 135...
Ive tried calling it by number also with
hMyCursor = LoadCursor(hInst,MAKEINTRESOURCE(135));

Try using LoadResource just to see if the cursor resource is being found.

If so, the problem must be that windows can't load it as a cursor for some reason.  If no, the problem is that the resource is somehow being left out of the project or is being included wrong.

From the Help:

Windows 95: The width and height of the cursor must be the values returned by the GetSystemMetrics function for SM_CXCURSOR and SM_CYCURSOR. In addition, the cursor bit depth must match the bit depth of the display or the cursor must be monochrome.
