Hello,
Please help me solve the following:
/*Now create the button.*/
hwndButton = CreateWindow (
"button", /*Builtin button class.*/
"Click Here",
WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
0,
0,
cx,
cy,
hwnd, /*Parent is this window.*/
(HMENU) 1, /*Control ID:1 */
((LPCREATESTRUCT) lParam)-> hInstance,
NULL
);
return 0;
break;
}
I get the error message: Macro 'Create WindowA' used with
only 10 args.
How do I resolve this?
Thank you,
Adock.
MSDN lists 11 params, but when I the autohelp lists the params as I type out the function it only lists 10 (int nHeight is missing). I normally use CreateWindowEx so I'm not too familiar with CreateWindow.
This is what's listed in the MSDN library:
HWND CreateWindow(
LPCTSTR lpClassName, // pointer to registered class name
LPCTSTR lpWindowName, // pointer to window name
DWORD dwStyle, // window style
int x, // horizontal position of window
int y, // vertical position of window
int nWidth, // window width
int nHeight, // window height
HWND hWndParent, // handle to parent or owner window
HMENU hMenu, // handle to menu or child-window identifier
HANDLE hInstance, // handle to application instance
LPVOID lpParam // pointer to window-creation data
);
I just check the msdn site and they list the same thing (as my msdn library). Weird?
(HMENU) 1, /*Control ID:1 */
Could be a confilict with some other ctrl.
I would use
#define IDD_MYDIALOG 10001
Check your resource.h for conflicts.
((LPCREATESTRUCT) lParam)-> hInstance,
AFAIK this struct is only passed on WM_CREATE. So this code is in response to a window being created? (or you are keeping a static to the pointer to the struct ie may not be valid pointer)
In my opinion you should keep the HINSTANCE as a global. Or at least a local to the winmain source file. I think this is the problem.
or look here for a couple of ways to get the HINSTANCE

Thanks to both of you.
I will take some time
to study your suggestions.
