UInt to CString and back

How can I convert from UInt to CString and back and LPTSTR to CString and back?

nm i think i got it. Though I get an error when I try to use CString:

Code:

---

error C2065: 'CString' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'str'
error C2065: 'str' : undeclared identifier

I have windows.h and string.g included.

from UINT to CString:
CString str;
str.Format("%i", 123);

Is it even possible to use CString in straight win32 API or is it MFC specific?

nope, it's not in Win32 API, you can use it in MFC.

Is there an alternative I can use?

I could use <string> but how can I convert from UINT to string and back?

The STL has a the sstream header.

Code:

---


#include <iostream>
#include <sstream>

int main(void) {
  using namespace std;

  istringstream from;
  ostringstream to;
  int i;

  to << 15;

  cout << to.str() << endl;

  from = to.str();
  from >> i;

  cout << i << endl;

  return 0;
}

That doesn't have anything to so with MFC however this code should be useful.
