Extract string from CString

[Rajkumar R]

is this useful,

CString sTemp = _T("Tag-10,OnOff-19,Switch-5,Lbl-10,Signal-22,trip-1");
int pos = sTemp.Find(_T("Lbl")) + 3;
CString resToken;
resToken = sTemp.Tokenize(_T("- ,"),pos);
if (resToken != "")
{
int num = _ttoi(resToken);
};

That goes against OP title. :-D

may be more, but i think it covers what it needed:confused:

What? No solutions that use GetBuffer()?? I am shocked and appalled. :)

Only for you, to keep horror alive

strok(sTemp.GetBuffer(), "Lbl-");

:-D

Ahhh yes - the world is balanced again. And bonus points for using the little-known strok() function hehe

Use CString::Mid(), as NishantB++ already said to you.

CString str = _T("Tag-10,OnOff-19,Switch-5,Lbl-10,Signal-22,trip-1");
AfxMessageBox(str.Mid(str.Find(_T("Lbl-"))+4,2));//4 and 2 may vary! Depends on your string.

I agree with 4 as he knows and is going to search using that string but if he knows 2 that means he already has the string with him and question is to find that string.

Here i have to get the number of Lbl..I mean 10.

Apparently, you did not read the entire comment, did you? It's also mentioned "Depends on your string".

then the solution is if he want to find the number of Lbl, when it is 100, he want to build again :omg:

Depends on the string, lbl10.exe, lbl110.exe ...

[Rajesh R Subramanian]

My mentioning "Depends on your string" states that he'd have to modify the code accordingly if the parameters change, so that it works always without having to rebuild. I thought it was pretty clear and anyone who fails to understand is just plainly dumb.

that is 2 to 3 when lbl is 100 that means he knows the length of string without the string i got. lbl10.exe no rebuild , lbl-100.exe no rebuild ... thanks :-D recalling ur mentioning of "Depends on your string"

:omg: if he is such a person, i think he never post this, don't u even think, he is in need of this plain dumb solution of counting exercise, as he has NiShantB++ post already.
