I am trying to convert an int to string and get an error.
I have the following...
string str="1";
int val;
val=atoi(str.c_str());
val++;
itoa(val,str,10);
On doing this I get the following error. Were could I have gone wrong?
error C2664: 'itoa' : cannot convert parameter 2 from 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' to 'char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
</char></char,struct>
THANKS.

string str="1";
int val;
val=atoi(str.c_str());
val++;
itoa(val,(char*)str.c_str(),10);
The code would serve your purpose but not be the optimized way of doing this.
Somethings seem HARD to do, until we know how to do them.

This is a bad idea. The return type is const char * and casting away the const is wrong and the compiler is correct in complaining.

string s= "1";
strstream str;
int n;
str << s;
str >> n;
n++;
str.clear();
str << n << '\0';
s = str.str();

Hi,
I am working on an application in which I am using MSFlexGrid.
I have 100 rows and 8 cols.
I am initializing all cells with some strings.
So when the user edits and saves, again when he retrives from the file, iam populating all cells with the saved strings like,
for(int i=0;i<100;i++)
{
for(int j=0;j<8;j++)
m_Grid.SetTextMatrix(i,j,s); //S is string which is read from file
}
It works fine in debug mode, but in release mode its giving an error like
"Subscript out of range".
Please if u have any idea help me.
Sunil.
Regards,
Sunil Kumar

i used the flex grid in release mode also. but i didnt face this sort of problem.
try to debug your application and see where exactly, you are getting this error.
other wise, you mail me your code then i can help you.
good luck.

hello chandu,
Thanks for the reply.
I solved the problem.Its not the problem with flexgrid.
The string was going out of bound.
One more thing, the compilation is taking some time if I include FlexGrid.
Is there any option to reduce it.
Regards,
Sunil Kumar

how much time does it take?
i mean, is there any difference between debug mode and release mode?

Please prefix your main thread subject with [SOLVED] if it is solved.
thanks.

Yeah, the difference is about 1.5 to 2 mins.

in this regard, i donot have any other clue except the following.
1.write one more application without grid and then with grid and see the difference.
2.try to compile your application in another system.
3.only thing you have to do is to localise weather the problem is with the code or grid or the system.
BTW, what is the size of your RC file is it normal or abnormal. just verify!
good luck.

I used to do that, back in my college days. I also used to keep some snacks handy. But of course, only in boring classes.
