Split functionality for MFC Cstring Class
How to Split a CString
object by deli开发者_JS百科meter in vc++?
For example I have a string
value
"one+two+three+four"
into a CString
varable.
Similar to this question:
CString str = _T("one+two+three+four");
int nTokenPos = 0;
CString strToken = str.Tokenize(_T("+"), nTokenPos);
while (!strToken.IsEmpty())
{
// do something with strToken
// ....
strToken = str.Tokenize(_T("+"), nTokenPos);
}
CString sInput="one+two+three";
CString sToken=_T("");
int i = 0; // substring index to extract
while (AfxExtractSubString(sToken, sInput, i,'+'))
{
//..
//work with sToken
//..
i++;
}
AfxExtractSubString
on MSDN.
int i = 0;
CStringArray saItems;
for(CString sItem = sFrom.Tokenize(" ",i); i >= 0; sItem = sFrom.Tokenize(" ",i))
{
saItems.Add( sItem );
}
In VC6, where CString
does not have a Tokenize method, you can defer to the strtok
function and it's friends.
#include <tchar.h>
// ...
CString cstr = _T("one+two+three+four");
TCHAR * str = (LPCTSTR)cstr;
TCHAR * pch = _tcstok (str,_T("+"));
while (pch != NULL)
{
// do something with token in pch
//
pch = _tcstok (NULL, _T("+"));
}
// ...
