//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])); 
//---------------------------------------------------------------------------------------
