The CPL_NEWINQUIRE message is sent to a Control Panel dynamic-link library (DLL) to request information about an application that the DLL supports.
lParam1
Specifies the application number. This number must be in the range zero through one less than the value returned in response to the CPL_GETCOUNT message (CPL_GETCOUNT – 1).
lParam2
Specifies a far pointer to a NEWCPLINFO structure. The DLL should fill this structure with information about the application. The NEWCPLINFO structure has the following form:
#include <cpl.h>
typedef struct tagNEWCPLINFO { /* ncpli */
DWORD dwSize;
DWORD dwFlags;
DWORD dwHelpContext;
LONG lData;
HICON hIcon;
char szName[32];
char szInfo[64];
char szHelpFile[128];
} NEWCPLINFO;
The Control Panel DLL returns zero if it processes this message successfully.
This message is sent once for each application serviced by the DLL. It is sent immediately after the CPL_GETCOUNT message. A DLL can use the switch block for this message to do application-level initialization when it receives this message. Memory should be allocated in response to the CPL_INIT message.
