vs和matlab混合编程

Question

在用vs和Matlab混合编程时遇到如下错误，请高人指点：
一、BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, void *pv)
{
    if (dwReason == DLL_PROCESS_ATTACH)
    {
        if (GetModuleFileName(hInstance, path_to_dll, _MAX_PATH) == 0)
            return FALSE;
    }
    else if (dwReason == DLL_PROCESS_DETACH)
    {
    }
    return TRUE;
}
错误 1 error C2664: “GetModuleFileNameW”: 不能将参数 2 从“char [260]”转换为“LPWSTR” C:\Program Files\MATLAB\R2011b\bin\libMyAdd.cpp
二、bool MW_CALL_CONV libMyAddInitializeWithHandlers(
    mclOutputHandlerFcn error_handler,
    mclOutputHandlerFcn print_handler)
{
    int bResult = 0;
  if (_mcr_inst != NULL)
    return true;
  if (!mclmcrInitialize())
    return false;
  if (!GetModuleFileName(GetModuleHandle("libMyAdd"), path_to_dll, _MAX_PATH))
    return false;
    bResult = mclInitializeComponentInstanceNonEmbeddedStandalone(  &_mcr_inst,
                                                                    path_to_dll,
                                                                    "libMyAdd",
                                                                    LibTarget,
                                                                    error_handler, 
                                                                    print_handler);
    if (!bResult)
    return false;
  return true;
}错误 2 error C2664: “GetModuleHandleW”: 不能将参数 1 从“const char [9]”转换为“LPCWSTR” C:\Program Files\MATLAB\R2011b\bin\libMyAdd.cpp 85vsmatlab
