use joystick with program?

[cyberpirate]

Hi I would like to somehow use a controller with my program. The code below is what I've tried to compile from this site

http://msdn.microsoft.com/en-us/library/ms713447.aspx

in Getting the Driver Capabilities

here is the code

#include<stdio.h>
#include<Windows.h>


int main()
{
	
	JOYINFO joyinfo; 
	UINT wNumDevs, wDeviceID; 
	BOOL bDev1Attached, bDev2Attached; 
	
	if((wNumDevs = joyGetNumDevs()) == 0) 
		return ERR_NODRIVER; 
	bDev1Attached = joyGetPos(JOYSTICKID1,&joyinfo) != JOYERR_UNPLUGGED; 
	bDev2Attached = wNumDevs == 2 && joyGetPos(JOYSTICKID2,&joyinfo) != JOYERR_UNPLUGGED; 
	if(bDev1Attached || bDev2Attached)   // decide which joystick to use 
		wDeviceID = bDev1Attached ? JOYSTICKID1 : JOYSTICKID2; 
	else
		return ERR_NODEVICE;
}

every time I build i get this

1>c:\users\cyberpirate\documents\visual studio 2010\projects\gamepad test\gamepad test\maincode.cpp(13): error C2065: 'ERR_NODRIVER' : undeclared identifier
1>c:\users\cyberpirate\documents\visual studio 2010\projects\gamepad test\gamepad test\maincode.cpp(19): error C2065: 'ERR_NODEVICE' : undeclared identifier

I think I'm missing an include, if so which one?

I think you are looking for mmsystem.h (make sure it's after windows.h)...

That's what it said on an MSDN site...

nope I put that in the #include and I got the same errors

[cran]

Well, since you are just returning main, then don't worry about it at all. Either make it up yourself, or return a 1 or something instead. I've found online people defining it, but don't really want to keep searching for this... define the values yourself in an enum or a #define or something...

well the only problem with that is I get these errors

1>MainCode.obj : error LNK2019: unresolved external symbol __imp__joyGetPos@8 referenced in function _main
1>MainCode.obj : error LNK2019: unresolved external symbol __imp__joyGetNumDevs@0 referenced in function _main

I didn't do this before because I have no idea what those are saying and I figured it would just be easier to find the include file

[cran]

that's a linker error...

you need to link Winmm.lib

Ok it compiled. Thanks!
