CString 2 integer and reverse

[macmac38]

Hello, i have a text file where i store a number. When i read the value in my szBuffer(CString) i like to cast this to an integer because i want to increment this value. After the incrementation i like to write the value back into the file. So cast from int to CString(szBuffer) Any ideas, code? Thanks, Mark

try this: iInteger=atoi(LPCTSTR(csCString)); iInteger++; csCString.Format("%d",iInteger); this should do it! greets, Jason

yeah, works great. And how is the function to cast int to CString??;) Thanks, Mark

C style: char buf[10]; int number = 5; sprintf(buf, "%d", number); CString bleh = buf; STL style: #include std::ostringstream str; int number = 5; str << number; CString bleh = str.str().c_str(); MFC style: CString bleh; int number = 5; bleh.Format("%d", number); Boost style (www.boost.org): #include int number = 5; std::string str = boost::lexical_cast(number); CString bleh = str.c_str();

Oh yes ok. I am still sleeping... Thanks, Mark

As i already wrote: if you are using the MFC CString class, simply use CString::Format(); else use sprintf(); examples: csCString.Format("%d",iInteger); or sprintf(cBuffer,"%d",iInteger); (where cBuffer is of type char*) greets, jason
