VS2010 & MFC Legacy support Compile error

[Kobi_K]

Hi all ,

I'm using VS2010 Ultimate with MS2010 And the C++ MFC Legacy R1.

I'm tring to compile a simple program ( first time with all the support)

I'v included the path library.

stdafx.ccp :

#include "NiUiComponent.h"

#include "NiDAQmxComponent.h"

using namespace NI;

I'm getting this builed error :

1>c:\program files (x86)\national instruments\measurementstudiovs2010\vcnet\include\niexception.h(466): error C2440: 'default argument' : cannot convert from 'const char [1]' to 'LPCTSTR'

1>          Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

1>c:\program files (x86)\national instruments\measurementstudiovs2010\vcnet\include\niexception.h(466): error C2548: 'NI::ThrowNiOleException' : missing default parameter for parameter 2

1>c:\program files (x86)\national instruments\measurementstudiovs2010\vcnet\include\nicommoncomponent.h(48): fatal error C1189: #error :  UNICODE not supported

any idea's ?

Hello -

When using NI MFC components, you must not use unicode libraries.  Measurement Studio MFC support does not support unicode, only multibyte.  You can fix this in one of two ways. 

• When creating a new MFC project, you can deselect the "Use Unicode libraries" checkbox.
  
  
  
  
• If you have an existing project, you can open the project properties and select "Use Multi-Byte Character Set" for the "Character Set" general configuration property.
  
  
  
  

One of these solutions should resolve the build errors for you.  Please let me know if it does not.
