I'm trying to find a C library for automating mouse clicks and keystrokes, something like the Python package AutoPy would be ideal.
Might have heard of Auto-it [URL] ...., which automates GUIs in Windows. Something like that would also be good, but my main OS is Linux.
I'm not sure whether it would be possible to create a shared library from the C source code in autopy.
I've been reading about libraries; How to make them, how to use them, the different types of libraries, etc..
When using a shared library, does the program require that library to be installed on the computer after the program has been compiled into an .exe?
Ie.. if somebody downloaded a "Helloworld.exe" that I had compiled on my computer using a shared library (that wasn't part of a standard operating system), would they also need that shared library on their computer for the program to run without errors?
and for Static Libraries, when I compile a program using a static library, does it include in the final binary only the functions of the library that are actually used, or does the compiler add in the entire library?
A test program of mine loads a shared library (.so file). A function call in the shared library throws an exception that I am trying to catch in the main function of my test program. (I know that exception is being thrown for sure, I wrote the library to do that.)
However in the main program, the exception is not being caught. The flow of program goes past the catch block like no error has occurred. I am using g++ and I load the shared file using -l option. Only trying to load the program statically I got the following error:
/usr/bin/ld: cannot find -lmy-shared-library
collect2: ld returned 1 exit status
Why the exception is not getting caught.
I want to create a simple shared library that exports a simple C API, just like llvm-clang.
The library should be compilable with any compiler and be used by a variety of languages, again just like clang.
For visual studio that is:
Code:
extern "C" __declspec(dllexport) void __cdecl myfunc(int arg);
The __cdecl is the issue here: i cannot seem to find a compiler agnostic way of specifying the use of cdecl.
So i went to see how my favorite C API libraries (ie clang) handle it.
none of them specify a calling convention at all!
Code:
#define CINDEX_LINKAGE __declspec(dllexport)
CINDEX_LINKAGE void clang_disposeIndex(CXIndex index); //exported
how does that work? How does the compiler know to use __cdecl and how would i link to it dynamically without that knowledge?
I have created a shared object in Ubuntu (libMYLIB.so). I am now trying to compile a simple test program (testmylib.c) to see if the shared object is properly built. I am getting an error that the build cannot find the shared object. My build command is:
gcc -lm -l /dir/mylib -lMYLIB.so -o testmylib testmylib.c
where /dir/mylib is where my source and libMYLIB.so reside.
What am I doing wrong?
I have a class "Result" with a single template function Set(const std::string& arName, T& val) and a specialization of this function Set<Real>(const std::string& arName, Real& val) where Real is a typedef for double. The class is in a shared library and I use it in my main program. If I do result->Set<GLOBAL::Real>("U", 100.0); the wrong template function is called!
I check this by the output with std::cout.
Maybe it's a problem with the typedef.
If I link the object file of the Result class directly to my main program (no shared library), it works.
typedefs.hpp:
namespace GLOBAL {
typedef double Real;
} results.hpp
#include <iostream>
[Code] ....
I want to know:
1. Pros and cons of shared libraries
2. How to create them(any tutorial link or book will be good)
3. Compare static libraries to dynamic ones
Is there any open-source graph visualization library like GraphX or Graph#? I need a library which lets me easily draw graphs, vertices and edges and apply various layouts to them. The support for GraphX and Graph# is really bad and their forum doesn't work ...
I dont want to do any advanced thing, just to create graphs and applying layout to them for maximum of 20 nodes.
I have tried Yworks, which is a commercial tool, but that one is way too expansive ...
I am making a game and want to make an updater that grabs the source code from a page on the web. Can this use things that are available to all platforms? It could just be something that grabs the text from the page and executing it (maybe using something like Python's exec() command ?) BTW I'm using mac

I'm trying to write a program that prompts the user to enter a math expression (i.e 2*x + x*x) and a value of x. Then generate the value of y. My real question is: Is there a way to put the content of a string into the source code?
Example:
string math_function;
double x, y;
cout << "Enter the function: ";
getline(cin, math_function);

For example, if one researched how to deep copy a map container and paraphrased a solution from a website, what is the proper format? Are there standards for citing works in code?
I am currently only citing the link to the source in my personal code and explaining what algorithm the source contains.
I use a programming language called layout which nobody here has probably ever heard of. It was discontinued over 15 years years ago but it was a very visual & easy to use piece of software - no coding required. In fact once you name all the variables on cards (forms) from then on it's just mouse clicking & occassionaly typing a number if required. It used blackboxes in a flowchart arrangement which were pre-done code for doing just about anything. i.e opening windows, handling numbers & text, files etc. I have written many programs with it including database management, quoting software & currently use it in my business to track my jobs & do invoicing & ordering. It's a pity it wasn't updated & still around today.

Back to the problem. Being a 16 bit program it was written to run on Windows 3.1 but still works on Windows 7!! as long as it is the 32 bit version. I need to write a program that will run on 64 bit W7 without resorting to using a virtual PC solution. I have tried to find something similar that I might be able to use instead but so far nothing comes close to Layout. I just remembered today that layout can produce not only .exe programs but also various versions of C/C++ including visual c++. So I got this idea that if I could get those files I might be able to stick them into a C compiler program to re-make a "modern" exe file.
I could just do a simple sample program & send the source code to them to see if it works on a 64 bit version of Windows 7. how I can do this myself to produce a working exe file.
#include <stdio.h>
#include <stdlib.h>

View 1 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.

I am stress testing my webservers and I need to code or port a C++ HTTP GET flood onto this C++ bot sourcecode. I believe I will need GetTickCount so I can specify the duration of the flood as well. I already have the C++ HTTP Flood .cpp and .h files but have no clue how to put it together onto this source. This will be easier to do over Teamviewer as I'm already using C++ 6.0 and have been with no issues.

I am in try to use PlPlot library (for plotting) in C with code::blocks IDE (ver 10.05) on windows-7 plateform. I downloaded "plplot-5.9.9.tar" and unzipped it. In documentation it is not very clear to me (I am not expert in using third party lib.), how this library can be used with code::blocks i.e. where I have to save the lib, what should be added in compiler and debugger settings etc. It also seems from document that "makefile" (linux type!!) is necessary for Windows also? I am also unaware of MSYS makefile generator (given on Wiki page) on windows?
