I am writing unit tests for some of my code and have run into a case where I have an object with a small exposed interface but complex internal structures as each exposed method runs through a large number of internal functions including dependancies on the object's state. This makes the methods on the external interface quite difficult...
Hi All, I have two windows services, the first one written in c# and the second written in unmanaged c++, I want to know how can I do two-way interprocess communication. Thanks All ...
I'm trying to extract some variables in my C++ code nested in blocks for example, if I have DEL_TYPE_NONE, DEL_TYPE_DONE, DEL_TYPE_WAIT, I'd like to match "DEL_TYPE_NONE" "DEL_TYPE_DONE" "DEL_TYPE_WAIT" I made my pattern like this, std::string pat("(?<=^[ \\t]?)[A-Z0-9_]+(?=,$)"); but I'm keep getting error message when compil...
I have the following use case , array of integers vector<int> containing elements 123 345 678 890 555 ... pos 0 1 2 3 4 Based on the bits representation I receive for e.g 101 then return 123 678 (Elements of the array with its position bits set) 0011 then return 678 890 00001 then retur...
In C++, what is the convention for including headers for class files in the "main" file. e.g. myclass.h class MyClass { doSomething(); } myclass.cpp doSomething() { cout << "doing something"; } run.cpp #include "myclass.h" #include "myclass.cpp" etc.. Is this relatively standard? ...
I mainly develop in native C++ on Windows using Visual Studio. A lot of times, I find myself creating a new function/class or whatever, and I just want to test that piece of logic I just wrote, quickly. A lot of times, I have to run the entire application, which sometimes could take a while since there are many connected parts. Is the...
Hi, I am not able to get out of these simple bugs, but would be great full if some one could answer to weed out from these errors. I included windows.h and some other necessary headers but couldn't able get out of it. Snippet of errors: error C2146: syntax error : missing ';' before identifier 'MMVERSION' error C4430: missing type sp...
I'm working on C++ framework and would like to apply automatic memory management to a number of core classes. So far, I have the standard approach which is class Foo { public: static shared_ptr<Foo> init() { return shared_ptr<Foo>(new Foo); } ~Foo() { } protected: Foo() { } }; // Example of use shared_...
I'm new to make and makefiles, so forgive me if this is very basic. I'm looking through some makefiles in my project and I'm seeing 2 types of targets -- targets that don't begin with a . character and targets that do. And from what I'm guessing, it seems like the ".target-name" targets are always executed, is my assumption true? I did...
I'd like to compile cpp file w/o turning off vi. I know the :!g++ file.cpp but I prefer :make so I added this line in .vimrc file au FileType C set makeprg=gcc\ % au FileType Cpp set makeprg=g++\ % but I keep getting "make: * No targets specified and no makefile found. Stop.** "message. can anyone tell me what is wrong with my ...
I have the following code: typedef void VOID; int f(void); int g(VOID); which compiles just fine in C (using gcc 4.3.2 on Fedora 10). The same code compiled as C++ gives me the following error: void.c:3: error: ‘<anonymous>’ has incomplete type void.c:3: error: invalid use of ‘VOID’ Now, this is something in external library and I ...
std::string sAttr(""); sAttr = sAttr+VAL_TAG_OPEN+sVal->c_str()+VAL_TAG_CLOSE; else where in the code I have defined const char VAL_TAG_OPEN[] = "<value>"; sVal is a variable that is retrieved off of a array of string pointers. This works fine in most of the system, windows and linux. However at a customer site, where to my belief...
Hi, I have a function which takes a triple pointer as an argument: int somefunction(tchar ***returnErrors); Does anyone know how to allocate the memory for the returnErrors parameter? Thanks! Niko ...
#define SAFE_DELETE(a) if( (a) != NULL ) delete (a); (a) = NULL; OR template<typename T> void safe_delete(T*& a) { delete a; a = NULL; } or any other better way ...
Why do I fail to extract an integer value into Num variable ? #include <sstream> #include <vector> #include <iostream> using namespace std; int main() { string Digits("1 2 3"); stringstream ss(Digits); string Temp; vector<string>Tokens; while(ss >> Temp) Tokens.push_back(Temp); ss.str(Tokens[0]); ...
I have a problem with the boost::asio::serial_port class reading from a GPS device (USB-Serial). Connecting the device and reading from it works fine, but when I disconnect and reconnect the device, read_some doesn't read any bytes from the port. As boost doesn't seam to detect that the serial port is gone ( is_open() returns true ), I ...
In my project we have a base exception. For handling showing error dialogs, log and such. Im looking for a way to handle all derived classes of that exception, I thought this would work: try { main_loop(); } catch (const MyExceptionBase* e) { handle_error(e); } As every child instance thrown could be represented by a pointer to it...
Like the title says, we’re looking for a way to catch all exceptions from a piece of C++ code, and wrap this in a dll. This way we can shield of the application that uses this dll, from any errors occurring in this dll. However, this does not seem possible with C++ under Windows. Example: void function() { try { ...
I've been evaluating profilers and memory checking tools for native C++ programs on Windows and all of them want to be installed and run with administrator privileges. I rarely log in as admin on my machine. If I need to install something or do something that requires administrative privileges, I use runas and it works pretty well. Is i...
Hello i been trying to get a tokenizer to work using the boost library tokenizer class. I found this tutorial on the boost documentation: http://www.boost.org/doc/libs/1 _36 _0/libs/tokenizer/escaped _list _separator.htm problem is i cant get the argument's to escaped _list _separator("","",""); but if i modify the boost/tokenizer.hpp...
