ostringstream Question 4 4 (4/30/2013 11:49:39 PM) comp.lang.c++ How can I clear/reset/initialize an ostringstream object? I've tried both clear() and flush() calls to reset an object I've used (so that I can reuse it), but neither works: subsequent uses only append ... mrc2323

stringstream Problems #2 6 6 (4/26/2013 10:52:10 PM) comp.lang.c++ I am trying to use stringstreams to parse some complex data. In the code below, myTest is a string that contains int (9), char ('M'), string ("45-49") and string (" Male Age Group 45-49") data fiel... mrc2323

STL Map Problem #2 3 10 (3/30/2013 10:24:27 PM) comp.lang.c++ I am developing a small (and seemingly simple) STL map application, yet I can't get a clean compile. Below is code that produces a compiler error on the "find" call, where the compiler doesn't accept th... mrc2323

Sorting Structure Data within Vector 2 15 (3/27/2013 7:20:41 PM) comp.lang.c++ I am trying to convert an array-based application to a vector-based implementation, mostly because I need to expand the data being processed beyond a fixed array I've declared (CTSMAX), but also to make ... mrc2323

Parsing (a Series of) Variables 22 15 (3/24/2013 12:38:42 AM) comp.lang.c++ How do I (or can I?) parse a variable number of numeric values from a line of text? Below is an example of a data line I need to parse (14 values, but there can be more or less): 1 37 36 4 7 5 ... mrc2323

A Better Way? 34 17 (3/8/2013 9:21:15 PM) comp.lang.c++ Is there a better way (less code, less convoluted, etc.) to access the last character of a string variable than this?: if(str2.at(str2.length()-1) != '/') str2 +="/"; ... mrc2323

Passing C++ string Results 16 25 (1/19/2013 10:41:34 PM) comp.lang.c++ I have the following function, but it fails after the first invocation whenever the length of the input variable is longer than the previous data. Specifically: strToUpper("5h"); // works s... mrc2323

Erase Last Character of basic::string Variable 6 48 (12/11/2012 12:11:35 AM) comp.lang.c++ How do I remove the last character of a basic::string? Specifically, I'm using fgets to read lines from a text file, and each ends with the characters '\10' and '\0'. When I assign the c-string variabl... mrc2323

2 Iterators/Iterator Math 2 44 (11/26/2012 3:42:55 AM) comp.lang.c++ I am trying to print/display a list of strings in 2 columns. My attempt to use 2 iterators (one for the first half of the list and another for the 2nd half) doesn't compile - and I can't establish the ... mrc2323

Parsing Numeric Data #2 3 31 (11/8/2012 3:42:35 PM) comp.lang.c++ The function below (parseNum) seems convoluted and possibly faulty...although it seems to work. In the code invocation (far below) the data is real-world, and I wish to parse only the first 6 numeric ... mrc2323

Preferred Style Question 13 42 (9/25/2012 4:39:22 PM) comp.lang.c++ What are some accepted ways to do the following calculation - and avoid the compiler warnings that expose conversion data loss? (I'm trying to compute the total time in seconds that a person has to co... mrc2323 (170)

Using Class Objects 9 36 (7/31/2012 8:38:41 PM) comp.lang.c++ I'm trying to learn and adopt some new programming techniques, and I've reached a roadblock. Specifically, although I have most of a class defined and declared, I don't know how to use it. In the c... mrc2323 (170)

Include Files Directory Structure 7 47 (6/10/2012 7:31:25 PM) comp.lang.c++ For years, I've been placing all my projects and all my various include files in a single directory (CPP). It's now quite large (and messy!), and I'm trying to convert my code to a newer compiler. This... mrc2323 (170)

Access Violation Problem #2 17 84 (6/2/2012 8:44:53 PM) comp.lang.c++ I have the following code that compiles but produces a "Access violation reading location..." runtime error when executed. I tried casting the first statement to (char*), but that produced the same fa... mrc2323 (170)

C-style Strings to LPCWSTR 12 92 (5/26/2012 2:48:56 AM) comp.lang.c++ How can I convert a C-style string variable to LPCWSTR? I have code that used to work on VC6.0 that didn't seem to care that a function call that accepts an LPCWSTR argument wasn't that type, but now th... mrc2323 (170)

fstream Buffers 33 42 (5/17/2012 8:34:40 PM) comp.lang.c++ I have the following routine that determines the time required to copy a large text file to another. I'm comparing this code to a class I wrote (too large to post here) that does text file I/o with explic... mrc2323 (170)

Some Basics - strings and Conversions 10 25 (4/16/2012 11:07:37 PM) comp.lang.c++ In the following code, even though the program executes, the 2nd prompt fails to process data. The 1st prompt requires 2 returns (why is that?), but the 2nd doesn't: it prompts, waits for data, and goes o... mrc2323 (170)
