Convert CString to std::string and vice versa

// convert from std:string to CString

CString errorMsg'

std::string encodeError = "Error 01";

errorMsg = CString(encodeError.c_str());

// convert from CString to std:string

CString csData = "f1db14dfa5d54f0b";

std::string ssData((LPCTSTR)csData);

Convert CString to char array

Again, when use CString, remember to include afxwin.h

char csRoom [20];

BSTR sRoom = "102";

CString myString1(sRoom);

strcpy(csRoom,myString1);

now, value from CString copied to char array

Convert BSTR to CString

When use CString, remember to include afxwin.h in your header.

BSTR sComPortNumber = "COM1";

//declare CString csComPortNumber and convert BSTR cComPortNumber to CString

CString csComPortNumber(sComPortNumber);

DONE.
