MSTcpIP.h errors in CVI 2012

[TheMann]

Hi 

I have been using LabWindos CVI 8.1 and I am now looking into upgrading to 2012, so i have downloaded the trial version from the NI website and installed it. 
When i open and go to compile my project which uses the Winsock2 library in CVI 2012 i get some stange errors inside mstcpip.h.

"MSTcpIP.h"(331,1) syntax error; found 'identifier' expecting ';'. 

#if (NTDDI_VERSION >= NTDDI_WIN2KSP1)
MSTCPIP_INLINE
BOOLEAN
IN4_ADDR_EQUAL(__in CONST IN_ADDR *a, __in CONST IN_ADDR *b)
{
    return (BOOLEAN)(a->s_addr == b->s_addr);
}

it is happening on the 3rd line which reads just BOOLEAN 

which has been defined by this code in WinNT.h

typedef BYTE BOOLEAN;
typedef BOOLEAN *PBOOLEAN;

where BYTE is defined in WinDef.h

typedef unsigned char       BYTE;   

I do have a typedef unsigned char Boolean; in my code but i don't think that should be a problem as C is case sensative. 

Any help would be greatly apreciated

Thanx

Hi TheMann,

Can you verify whether you are including the windows.h header file before the MSTcpIP.h header file is included?

If you are not calling #Include <windows.h> before this header, please rearrange your #Include calls so that #Include <windows.h> comes before #Include <mstcpip.h>.

Please let me know if this helps.

Hi Daniel,

Thanx for the reply 

I had my includes in the following order

#include <stdlib.h>
#include <stdio.h>
#include <winsock2.h>
#include <windows.h>
#include <MSTcpIP.h> 

#include <Iphlpapi.h>

//#include "C:\Program Files (x86)\National Instruments\CVI81\sdk\include\MSTcpIP.h"

If i directly link to the old CVI8.1 file it compiles fine without errors.  

I just rearanged the includes into this order 

#include <windows.h>
#include <MSTcpIP.h>

#include <stdlib.h>
#include <stdio.h>

#include <winsock2.h>

#include <Iphlpapi.h>

And now it compiles fine, not really sure why but as long as it works 🙂 

Thank you very much for your help,

-Jon
