[求助] 建立单文档MFC的工程怎么调用DLL文件

// Then have windows load the library.

???????X?e?N?X????Instance = LoadLibrary("./refprop.dll");

// Then get pointers into the dll to the actual functions.

// Now use the functions.

// Refprop variables that need to be defined
//
// nc = Number of components in the mixture
// x[NumberOfComponentsInMixtures] = Mole fraction of each component
// ierr =An integer flag defining an error
// hf[] = a character array defining the fluids in a mixture
