When you are creating a project or program, how do you number your versions?
Like when you release it, it becomes v1.0, am i right?
then every release or build after that might become v1.1 or v1.0001 or v1.0.1.2
Is there a certain global system for how you Number your versions or is it just up to the developer?
In my program I am supposed to call isEqualTo with a user defined class type, and print out if my two numbers being compared are equal or not. I had to write two versions of this, one with just a template which works fine, but when I implemented the class, all the sudden my program just spews out true no matter if actually equal or not. Here is what I have so far:
#include "stdafx.h"
#include <iostream>
#include "UserClass.h"
using namespace std;
template<typename T>
bool isEqualTo(T value1, T value2){
if (value1 == value2)

Say I have two projects A and B. A depends on B. If project A defines a macro to be 100 and project B defines the same macro to be 200. In project A, if I use this macro, what value would this macro be? Let's just forget macro is evil for the time being. Let's also forget that it is not good to define the same macro twice for the time being.

View 2 Replies View RelatedI am working on VS2008. I have two separate projects which have almost same functionality along with same file names but few are different. So I decided to use the same .cpp and .h files for both the projects. Both are Dialog based applications.
So what I did is I merged the source code changes to one by using #ifdef XXXX in all the common .cpp and header(.h) files.
I also moved the .rc file and .vcproj file to other project (As they were of different name).
The problem is with the resource.h file, as it is the file with the same name in both the project. By using #ifdef XXXX in .cpp files the compilation is working file but here in resource.h the resource is getting corrupted and the diglogs are not getting displayed.
how to merge two resource.h files to one.
Why certain projects always roll their own data structures/utililiy classes rather than using the C++ standard libraries? such as linked lists and queues? Is there a particular reason for this?

Is there any code I can use to determine my compiler version and which Standard It uses? I know the following code determine that my compiler followed ANSI But how about a version of that? ****My OS is now Ubuntu
Code:

I am/we developing in C and we have a number of different programs. We also have problem to keep track of different versions of a specific exe file.
Is there any way to add version number when build a file so the version is added in the properties.
I doing this in a MFC c++ project in a .rc file. Is there a way (or a similar way) of doing this in C? Here its stored in the details section with product version 6.0.8:
Just wondering if there was a standard way people add a version number to their c++ code? I can just define a variable or #define and write the version number to that, but wanted to know if there is a standard method people use?

I have been trying to compile a static version of the boost libraries, however when I try to launch the program it says fatal error LNK1104: cannot open file 'libboost_serialization-vc100-mt-s-1_53.lib'
I have checked in the boost/stage/lib folder and that file is not there. I compiled boost with b2 link=static yet the file still isn't there.

I have a set of projects. Each one builds either a static library or an executable. What I'd like to do, is at build time I want to embed a version string representing the version of the executable as well as the version of each library. These version strings will come from an external source (in my case it's based on a "git describe" call, but that's beside the point). Embedding such strings can be highly valuable for traceability. (Versions of 3rd-party libraries are not necessary.)
I'm using qmake as my build system, but this should work more or less similarly with any build tool. What I'd ideally like to do is define this process in such a self-contained way that a an absolutely minimal amount of additional code is required in order to leverage it. Preferably, nothing more than an include(version.pri) in each project's .pro file in order to collect the versions. (Retrieving them later, such as to respond to a --version command-line flag, can be done via traditional C++ methods.)
What I've done so far is to define a singleton VersionTracker class, and then tweak the build system so that "MODULE" and "VERSION" are preprocessor symbols defined at build time. I've also tweaked the build system so that a file in each project, version.cpp, is rebuilt (and regenerated if necessary) on every build regardless of changes. This source file can capture the information in the preprocessor symbols into each static library and the executable.
Now, here's the problem. How can I get the information from those version.cpp files into the VersionTracker class? I thought I could use a global object's constructor to do it, but it turns out the symbols are stripped out when the static libraries are linked so I only get the executable's version. I also found a page on stackoverflow detailing a very clever way to call a registration function at class definition time, but again the class definition appears to be stripped out if it's defined in the version.cpp file of a static library and not referenced elsewhere.
Everything I've read basically says you either need to use linker flags to prevent symbol stripping entirely, which is probably an adoption-killer for this hack, or you need to use an explicit registration function called from the executable. I'd prefer to avoid this since it is just another thing a programmer could forget to update when a library dependency is added or removed.
My last idea, which I haven't tried yet, would be to put each version.cpp into a separate static library from the one it is describing. This version-only library could be linked without symbol stripping. I don't love this concept but it might work.
I haven't yet figured out how shared libraries can be worked into this framework at all. I'll worry about that after I get static libraries working.
Is there a way I can extract Machine / Hardware ID and OS Version using VC++?

I have a mobile application for android coded in javascript and a windows form coded in c#. I want my mobile app to send some data to the c# program. It is fine if the transmission is not secure. I searched the net. I found a site called pastebin.com. Unfortunately it provides api for posting and reading data. However I want something, where I can store,read as well as EDIT the data.

Right now I am trying to set up a database so that my program, which currently just appends its results onto a text file, will instead store each result into a database, because this will make things much easier to access than trying to read specific results from an ever-larger, disorganized text file.
View 2 Replies View RelatedI tried to do this with _spawnl(), but first of all I'm not sure how to properly ask for the path to iexplore.exe, as I'm sure it will change every time MS gets a whim to move it. I know there's a GetWindowsDirectory() call, but that's not where IE resides (its in "C:Program FilesInternet Exploreriexplore.exe" in XP, Lord know where on win 7 or 8).
Also, even temporarily hard coding the path to make it launch with spawnl(), I can't seem to get my html document to display. I know the path to that is right (since I put it there ).
char * pFile = "someFile.htm";
char * pCmd = "C:Program FilesInternet Exploreriexplore.exe";
int res = _spawnl(_P_NOWAIT, pCmd,pCmd, pFile, NULL); // also tried without specifying pCmd 2x
if (res == -1) MessageBox("Can't Open File.");
So my second question would be, how to you PROPERLY pass the file to view as an argument.

View 3 Replies View RelatedI am just starting out learning C and I am using MinGW, Widnows 7, and cmd.exe.I am starting from scratch and learning very short and simple programs, like 20 lines long.After I use MinGW (gcc) to compile, the programs start up rather slowly, sometimes up to about 3-5 seconds. One with a big nested loop even took about 15 seconds to load. After they run once, the next time they run, it's instant.
Last time I learned from this book, I don't remember them starting so slowly. I use the command "gcc sample.c -o sample".It just concerns me that these tiny little programs are starting up so slowly. I'm scared it's a problem with my computer or MinGW installation. When I start making more advanced programs, I don't want them running slower than they ought to be.
I find type casting to be very hard to grasp, I am not sure why. I understand how it works I suppose, but I find it hard to grasp why it would be needed in programming. So my question is, how often is type casting used in general programs? Is there an easier way I could be trying to teach myself about it? I am just using the tutorials provided by this site.
