Since with this MACRO:

#define	MOUSE_CHILD_FUNCT(x, y, w, h, cursor, mouse_flags, function)	{MOUSE_RECT_CHILD, {x, y, w, h}, cursor, helpid, mouse_flags, 0, function, NULL},

(which mysteriously omits helpid in the formal parameters)and this code:

MOUSE_BEGIN( switch_strobe_mouse_rect, HELPID_GAUGE_LIGHT_SWITCH_STROBE, 0, 0 )	MOUSE_CHILD_FUNCT( 0, 0, 43, 73, CURSOR_UPARROW, MOUSE_LEFTSINGLE, switch_strobe_mcb)MOUSE_END

You get this error:

B206B3.Switch_Strobe.c(62) : error C2065: 'helpid' : undeclared identifier

I'm thinking this redefinition of the MACRO fixes it:

#define	MOUSE_CHILD_FUNCT(x, y, w, h, cursor, mouse_flags, function, helpid)	{MOUSE_RECT_CHILD, {x, y, w, h}, cursor, helpid, mouse_flags, 0, function, NULL},

by then using this code:

MOUSE_BEGIN( switch_strobe_mouse_rect, HELPID_GAUGE_LIGHT_SWITCH_STROBE, 0, 0 )	MOUSE_CHILD_FUNCT( 0, 0, 43, 73, CURSOR_UPARROW, MOUSE_LEFTSINGLE, switch_strobe_mcb, HELPID_GAUGE_LIGHT_SWITCH_STROBE)MOUSE_END

Comments?

The original version of that macro works for me without any problems.#define MOUSE_CHILD_FUNCT( x, y, w, h, cursor, mouse_flags, function ) {MOUSE_RECT_CHILD, {x, y, w, h}, cursor, HELP_NONE, mouse_flags, 0, function, NULL},

I use Visual Studio .NET 2003 btw. May be it's a compiler thing.

Try this:MOUSE_BEGIN(switch_strobe_mouse_rect,HELP_NONE, 0, 0 ) MOUSE_PARENT_BEGIN(0,0,43,73,HELPID_GAUGE_LIGHT_SWITCH_STROBE) MOUSE_CHILD_FUNCT(0,0,43,73,CURSOR_UPARROW, MOUSE_LEFTSINGLE, switch_strobe_mcb) MOUSE_PARENT_ENDMOUSE_END
