Changed Cursor not displaying

[richsb]

Hi,

I have a Dialog app that has WM_ONMOUSEMOVE message map function created from which I catch a certain area of the window. When the cursor is over this area I wish to change to default arrow cursor with one of my own.

The problem that I have is that the code below compiles and runs, but when over my chosen area the cursor dissapears. Within the WM_ONMOUSEMOVE function I have the following code :-

LPCTSTR myCursor = "IDC_CURSOR1" [COLOR=green]// my cursor created in the editor and listed in the resource.h file[/color]

HINSTANCE hInstance;
hInstance = AfxGetInstanceHandle(); [COLOR=green]// catch a handle to the window[/color]

HCURSOR hCursor;
hCursor = (HCURSOR) LoadImage
           (hInstance,
            myCursor,
            IMAGE_CURSOR,
            32,
            32,
            NULL
            );

::SetCursor(hCursor);

I have tried all permatations using this function and the now redundant LoadCursor(), CopyCursor(), ShowCursor()plus other functions.

Any help appreciated.

If it is not broke, don't fix it!!!

1) Does hCursor return a valid value?

2) Try SM_CXCURSOR and SM_CYCURSOR instead of 32, 32

3) Last parameter, try LR_DEFAULTCOLOR

4) If all else fails, does this work

HCURSOR hhand = LoadCursor (NULL, IDC_HAND);
::SetCursor (hhand);

It turns out that the hCursor is unused with the following messege in debug:-

hCursor : 0x00000000
unused
CXX0030 : Error : expression cannot be evaluated

I guess there is more handling of the resource handle to be done, such as using FindResource();

Any suggestions?

Got it sorted,

It was as simple as using the cursor ID number rather than the cursor name as follows, more importantly using the hash sign as well (#).

LPCTSTR myCursor = "#151"
