MultiByteToWideChar WideCharToMultiByte

//-------------------------------------------------------------------------------------

//Description:

// This function maps a character string to a wide-character (Unicode) string

//

//Parameters:

// lpcszStr: [in] Pointer to the character string to be converted

// lpwszStr: [out] Pointer to a buffer that receives the translated string.

// dwSize: [in] Size of the buffer

//

//Return Values:

// TRUE: Succeed

// FALSE: Failed

//

//Example:

// MByteToWChar(szA,szW,sizeof(szW)/sizeof(szW[0]));

//---------------------------------------------------------------------------------------
