I am trying to build a server sided HTML rendering based browser much like skyfire. I am evaluating the technologies that I would need to build this. When a user types in a www.yahoo.com on the client box, there is a session started on the server, then i grab the screenshots and send them in a RTP stream back to the client. To do the RTP...
I am trying to connect to a single USB device using the USB host port on an Atmel processor. I have an embedded system with limited memory and no OS. I want to implement a simple dedicated host to interface to a single USB slave device. Can anyone guide me to a simple USB host implementation? The processor is the Atmel AT91SAM9261S. ...
What I want is something similar to STL vector when it comes to access complexity, reallocation on resize, etc. I want it to support arbitrary index range, for example there could be elements indexed from -2 to +7 or from +5 to +10. I want to be able to push_front efficiently. Also I want two-way resize... I know I could write something...
I have a C++ code which I am compiling using VC7 and it is taking a lot of time to build it. Is there any way I could profile it and find why it is taking time to build ? ...
I heard you should never throw a string because there is a lack of information and you'll catch exceptions you dont expect to catch. What are good practice for throwing exceptions? do you inherit a base exception class? Do you have many exceptions or few? do you do MyExceptionClass& or const MyExceptionClass& ? etc. Also i know exceptio...
Can anyone suggest a way of stripping tab characters ( "\t"s ) from a string? CString or std::string. So that "1E10 " for example becomes "1E10". Thanks in anticipation. ...
Currently I have a set of SWIG wrappers for my classes and it all builds. I can create a lua virtual machine and load my wrappers, but at that point I'm flummoxed. Googling tells me how to shove put c++ in lua in swig, but not how to put lua in c++. Really all I want to do is manage to instantiate a lua object and pass it my main game e...
I need to create TCP/IP headers manually for my application. For that i used Raw socket. My system os is win xp (SP3). My code compiles fine :) but it throws a run time error: Initialising Winsock...Initialised successfully. Creating Raw TCP Socket...Raw TCP Socket Created successfully. Setting the socket in RAW mode...Successful. E...
As the topic says I'm very new to c++, but I have some experience with java. To start learning c++ I had the (not very original) idea of making a simple command line calculator. What I'm trying to do is store the numbers and operators in a binary tree. #include <iostream> using namespace std; class Node { bool leaf; double num; c...
Hi all, I have a case in which I have to read an input file in the C'tor, but sometimes this file doesn't exist. This object is usually held statically, so its C'tor is called while loading the dll. I can't catch the exception I throw if the file doesn't exist because it's too early, and my executable crashes in an ugly way. I know it's...
Hi All I have a customized exception class. say class CustomExcep{}; My Application is a middleware made of C++. It is a webservice which is used for the communication between Java based web Front-end and the DCE Backend. whenever the DCE Backend is not running or down due to some core dumps, the application throws the CustomExcep. I...
Hi I always asked myself if it would be possible to make a Java2C++ Converter. Maybe a Tool that converts the Java Syntax to the C++ Syntax.. i am aware that the languages differ .. but simple things like loops where the semantic matches 1 on 1 .. is there such a tool . or is it possible to make one ? ...
I want to do the following: Define a map between a string and any kind of object (may be a list, integer - anything). The keys to the map can be as follow (the values are, again, not important): "AAA/123" ==> 1 "AAA/" ==> 2 "BBB/" ==> 3 "CCC/*" ==> 4 "CCC/123" ==> 5 Now, the trick is I want to find the right values given the following st...
I have a problem, I have an application which has a toolbar icon to launch the system onscreen keyboard. This all works fine with the exception of Windows Vista and Windows 7 beta. The UAC appears to be getting in the way and preventing the osk.exe from running. I have read that because it is used on the logon screen it will not promp...
I need to be able to create guids on the fly. Is there a way to do that in MFC? I see how to do it in .net, but we haven't gone there yet. If not, do you have pointers to some code I can use? ...
I have a static library that may get linked into either a .exe or a .dll. At runtime I want ony of my library functions to get the HMODULE for whatever thing the static library code has been linked into. I currently use the following trick (inspired from this forum): const HMODULE GetCurrentModule() { MEMORY_BASIC_INFORMATION mbi ...
Dear all, The following string of mine tried to find difference between two strings. But it's horribly slow as it iterate the length of string: #include <string> #include <vector> #include <iostream> using namespace std; int hd(string s1, string s2) { // hd stands for "Hamming Distance" int dif = 0; for (unsigned i = 0;...
Probably a simple question but I only have Linux to test this code on where __declspec(dllexport) is not needed. In the current code __declspec(dllexport) is in front of all files in the .h file but just in front of like 50% of the functions in the cpp file so I am wondering if they are really needed in the cpp file at all ? ...
I am creating a program in c++, which I want to be able to have the option to have users let it auto start in windows. So when a user starts his computer, windows will auto start this program. I have read stuff about modifying the registry or putting it in the startup folder, but what would be the best "clean" way to do this? ...
I currently have the following lua code: g = engine.CGeometry() vertexes = {} vertexes[1] = 0 vertexes[2] = 0 vertexes[3] = 0 vertexes[4] = 0 vertexes[5] = -1 vertexes[6] = 0 vertexes[7] = -1 vertexes[8] = 0 vertexes[9] = 0 print "adding vertexes" g:SetVertexes(vertexes) where g...
