Ok the zserial.cpp compiles fine but the joystick.cpp doesnt it has problems with the line
DialogBox( hInst, MAKEINTRESOURCE(IDD_JOYST_IMM), NULL, MainDlgProc );
with the error
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(41) : error C2664: 'DialogBoxParamA' : cannot convert parameter 4 from 'long (struct HWND__ *,unsigned int,unsigned int,long)' to 'int (__stdcall *)(struct HWND__ *,unsigned in
t,unsigned int,long)'
None of the functions with this name in scope match the target type
have i set up the project wrong or something??
also it comes up with errors
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(60) : error C2065: 'zSerialOpen' : undeclared identifier
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(97) : error C2065: 'zSerialClose' : undeclared identifier
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(303) : error C2065: 'zSerialWrite' : undeclared identifier
which doesnt make sense as these were declared in zserial.h
could anyone tell me where im going wrong?

Ok the zserial.cpp compiles fine but the joystick.cpp doesnt it has problems with the line
DialogBox( hInst, MAKEINTRESOURCE(IDD_JOYST_IMM), NULL, MainDlgProc );
with the error
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(41) : error C2664: 'DialogBoxParamA' : cannot convert parameter 4 from 'long (struct HWND__ *,unsigned int,unsigned int,long)' to 'int (__stdcall *)(struct HWND__ *,unsigned in
t,unsigned int,long)'
None of the functions with this name in scope match the target type
have i set up the project wrong or something??
also it comes up with errors
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(60) : error C2065: 'zSerialOpen' : undeclared identifier
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(97) : error C2065: 'zSerialClose' : undeclared identifier
c:\program files\microsoft visual studio\myprojects\bluecar\joystick.cpp(303) : error C2065: 'zSerialWrite' : undeclared identifier
which doesnt make sense as these were declared in zserial.h
could anyone tell me where im going wrong?
