I am getting the error HMODULE LoadLibraryW(LPCWSTR)': connot convert argument 1 from 'const char [10]' to LPCWSTR' and argument of type "const char *" is incompatible with parameter of type "LPCWSTR"
Can anyone help me?

typedef MMRESULT(__stdcall *timebeginperiod) (UINT Period);
timebeginperiod TimeBeginPeriod = (timebeginperiod)GetProcAddress(LoadLibrary("winmm.dll"), "timeBeginPeriod");

typedef MMRESULT(__stdcall *timebeginperiod) (UINT Period);

// timebeginperiod TimeBeginPeriod = (timebeginperiod)GetProcAddress(LoadLibrary("winmm.dll"), "timeBeginPeriod");

// use the narrow character versions  
timebeginperiod TimeBeginPeriod = (timebeginperiod) GetProcAddressA( LoadLibraryA( "winmm.dll" ), "timeBeginPeriod" );

Thanks, it worked.

Also can you help me with this?
I'm getting this error:
'TimeBeginPeriod': redefinition; multiple initialization

timebeginperiod TimeBeginPeriod = (timebeginperiod)GetProcAddress(LoadLibraryA("winmm.dll"), "timeBeginPeriod");

Missing closing parenthesis.

// timebeginperiod TimeBeginPeriod = (timebeginperiod)GetProcAddress(LoadLibraryA("winmm.dll"), "timeBeginPeriod");

   timebeginperiod TimeBeginPeriod = (timebeginperiod)GetProcAddressA(LoadLibraryA("winmm.dll"), "timeBeginPeriod") );

Prefer to do this in multiple steps, with validation:

const auto lib = LoadLibraryA( "winmm.dll" ) ;

if(lib) 
{
      // avoid two names that differ only in case
      const timebeginperiod pfn_time_begin_period = (timebeginperiod)GetProcAddressA( "timeBeginPeriod" ) ;

      if( pfn_time_begin_period )
      {
              // use pfn_time_begin_period 
      }
      else std::cerr << "could not find exported symbol\n" ;
}
else std::cerr << "failed to load library\n" ;
