Why do you need it (most of the times you really don't need)?

5 solutions

Solution 3

1. CString::GetBuffer
2. (char*)LPCTSTR(your CString var)

Solution 4

Some of the other solutions gave me some trouble sometimes truncateing some of the CString, but this one is simple & it works as intended!!

{Please notice the Capital %S in sprintf}

C#

CString z(_T("I love CString!\r\n"));
char sz[100];
sprintf(sz, "%S", z);

Solution 2

If you can change ar, an approch like this one would be a lot better...

C++

class ar
{ 
public:
    void set_value(const CString &data) { m_data = data; }
    CString &get_value() { return m_data; }
    const CString &get_value() const { return m_data; }

private:
    CString m_data;
};

function(const CString &data)
{
    ar.set_value(data);
}

Solution 1

Try it :) :

C++

void function(const CString& cszData)
{
  USES_CONVERSION;
  char* pchTmp(T2A(cszData));

  strcpy_s(ar.value, _countof(ar.value), pchTmp);
}

It does answer the question... but it is not recommanded to do that if not necessary (that is if you cannot change ar structure). See my solution.
